Roto-Gro World Wide (Canada), a wholly-owned subsidiary of Roto-Gro International, has applied to the Deep Space Food Challenge as part of its first step into the space agriculture sector.

Administered under an international collaboration between National Aeronautics and the Space Administration (NASA) and the Canadian Space Agency (CSA), the international competition aims to incentivize the development of novel food production technologies needed for long-development space missions and terrestrial applications.

Roto-Gro’s application highlight’s the technological diversification and adaptability of its patented proprietary indoor vertical farming technology.

Astronauts’ food needs changing as missions evolve

Astronauts currently receive food from spacecrafts regularly launching from Earth, for example to the International Space Station.

However, NASA and the CSA recognize that as the distance and duration of space exploration missions increase, the current method of feeding astronauts will no longer be sustainable.

Future astronauts will be required to use food production systems on their voyages and be self-sustaining. The challenge aims to inspire the agricultural industry to help bring innovative food production technologies to space, reducing the need for resupply from earth and ensuring astronauts have continuous safe and nutritious food supplies.

The ability to develop sustainable food production is considered the crucial next step for longer-term human presence on the lunar surface and the future missions to Mars.

The challenge is not only about space exploration but also missions in extreme arid and resource-scarce environments on Earth. Like space, input efficiency will be key, including the efficient use of water and electricity to reduce resources needed for food production here on Earth.

Adapting Roto-Gro’s existing models key to space success

A new Roto-Gro rotational garden system — branded Roto-Gro Beyond Earth — will be designed with engineering adapted-off components from its existing Model 420 and Model 710 rotational garden systems.

Roto-Gro Beyond Earth will be a smaller, more portable version of the Model 420 but feature the injection feed system from the Model 710, significantly reducing the required resource inputs while maximizing nutritional outputs when compared to other indoor farming technologies.

Roto-Gro CEO Michael Di Tommaso said Roto-Gro Beyond Earth will enhance the already existing, unique benefits of its rotational garden systems, optimizing both the operational efficiencies and yield per m2, which is crucial to the development and prospective use of food production systems in space.

“The technology developed to form the application to the challenge is astoundingly demonstrating the vast applicability and sheer innovation of the company’s technology,” Di Tommaso said.

He said the company had developed several key relationships with organizations currently providing food system solutions for long-duration space voyages, along with others focused on using space to solve problems we are experiencing on earth.

“We look to develop and foster these relationships moving forward, further strengthening our position in the sector,” Di Tommaso said.

He said entering the space agricultural sector was a natural progression for Roto-Gro, supporting its vision to provide sustainable technological solutions for agricultural cultivation, critical to ensuring global food security.

“Food system innovation is crucial to our progression in space, and we are excited with the prospect of moving to the next phase of the Deep Space Food Challenge, while also generating other opportunities to develop and implement Roto-Gro’s technology in the industry,” Di Tommaso said.

 Roto-Gro global forecasts international growth

Established in 2015, Roto-Gro is continuing to attract interest on a global scale.

The company recently partnered with agriculture company Verity Greens Inc. who has signed a binding $10M Technology License to purchase 624 RotoGro Model 710 rotational garden systems, with the first, flagship indoor vertical farming facility to be built in Canada.

The deal is expected to generate long-term, sustained recurring revenue with Di Tommaso hailing it as not only a “win-win” for both companies but a venture that works on a socially responsible level by helping tackle global food shortages.

“RotoGro will introduce our revolutionary technology into the booming indoor vertical farming space, while Verity Greens, utilizing the RotoGro Garden Systems and supporting technology, will operate with a viable and cost-effective competitive advantage,” he said.

“Verity Green’s first facility also serves to further its objectives – to roll out indoor vertical farming facilities globally utilizing RotoGro’s technology, not only to generate substantial revenue for both companies but also to provide a truly sustainable solution to address the issues caused by food insecurity.”

Growing Vegetables In Antarctica In the EDEN ISS Project

Status Report From NASA Biological & Physical Science

July 1, 2021

Scientific research studies to determine how to grow plants in extreme environments on Earth will help NASA understand how to grow plants in extreme conditions on the moon or Mars. Growth of crop plants in lunar or Mars habitation systems will be essential for meeting astronaut nutritional needs and maintaining astronaut health during long-duration exploration missions. To facilitate these studies, an international agreement between NASA and DLR (German Space Agency) has been signed to enable research collaboration on the EDEN (Evolution and Design of Environmentally-Closed Nutrition-Sources) ISS project at the German Neumayer III Station in Antarctica.

The EDEN module is designed to simulate a plant production system that might operate in a surface setting in space and is used to provide fresh food to the 10 “over-wintering” EDEN crew members. Biological and Physical Sciences research has been conducted at the EDEN site under the Space Biology grant titled “Spectral Imaging within the EDEN ISS Project - An Antarctic Analog for Enhancing Exploration Life Support.” For this Space Biology grant, PI Dr. Robert Ferl and Co-I Dr. Anna-Lisa Paul (both from the University of Florida) traveled to Antarctica to conduct their research.

Kennedy Space Center (KSC) continues to support EDEN ISS. For this project, KSC contractor Jess Bunchek is in residence in Antarctica as one of the crew members at Neumayer III where she is operating and maintaining the plant chamber with the help of DLR colleagues at Bremen, Germany. She is growing crops that have been grown on ISS for BPS-funded experiments to compare growth in the two settings. She is tracking her time spent on horticultural activities, measuring the yields of the different crops, taking microbial samples for post-mission analysis, and helping administer surveys to the crew to obtain their opinions on having fresh food in their diet. Jess arrived in Antarctica in January 2021 and will be there until February 2022. Follow Jess as she journals her account of the journey to EDEN ISS.

Start of A New Series of Tests For Plant Cultivation on The Moon And Mars

MAY 4, 2021

NASA Seeds Germinate in

DLR’s EDEN ISS Greenhouse

Start of a new series of tests for plant cultivation on the Moon and Mars

Nine weeks of darkness and temperatures down to minus 50 degrees Celsius. Under these harsh conditions of Antarctica, NASA and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have begun a joint series of experiments on vegetable cultivation techniques for use on the Moon and Mars. Until early 2022, NASA guest scientist Jess Bunchek will research how future astronauts could grow lettuce, cucumbers, tomatoes, peppers, and herbs, using as little time and energy as possible.

To this end, she will be working at DLR’s EDEN ISS Antarctic greenhouse, where she will put greenhouse technologies and plant varieties to the test. She is also recording any effects the greenhouse and its yield have on the isolated hibernation crew in the perpetual ice. Bunchek is part of the 10-person overwintering crew on Neumayer Station III, operated by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI).

First harvest – Lettuce, mustard greens, radishes and herbs

“The polar night will soon begin here on the Antarctic Ekström Ice Shelf. With the nine other members of the overwintering crew, it almost feels like we are alone on another planet,” says Bunchek. “In this hostile world it’s fascinating to see the greenery thrive without soil and under artificial light.”  Bunchek is a botanist from the Kennedy Space Center, where she has primarily supported the VEGGIE project on the International Space Station (ISS) She was able to sow the first seeds in recent weeks, following a technical reconditioning of the EDEN ISS platform conducted by her and the DLR team. The first harvest, which included lettuce, mustard greens, radishes, and various herbs, followed a few days ago.

NASA seeds and new nutrient supply system

The EDEN ISS greenhouse uses particularly robust varieties that were selected by the EDEN ISS Project team and from experiments at NASA’s Kennedy Space Center and as part of the VEGGIE project on the ISS. The DLR/NASA mission also aims to record and compare the growth and yield of the crop varieties under the conditions of the Antarctic greenhouse. An additional focus will be studying which microbes thrive in the greenhouse alongside the cultivated plants.

NASA will also be testing a plant watering concept in the EDEN Module that can operate in u-gravity settings, like the ISS.  The system contains the water and delivers it to the plants by a passive method.  “This will provide a side-by-side comparison with the aeroponically grown plants of EDEN ISS” says Ray Wheeler, plant physiologist at NASA’s Kennedy Space Center. In aeroponic irrigation, the roots of the plants without soil are regularly sprayed with a nutrient solution.

Crew time – a precious commodity

Sowing, harvesting, tending, cleaning, maintaining, calibrating, repairing and conducting scientific activities. Bunchek records every second of her activities in the Antarctic greenhouse with a special time-recording eight-sided die, as crew time will be a precious commodity on future missions to the Moon and Mars. “In an initial test run of the greenhouse during the 2018 mission, we found that operations still took too much time,” explains EDEN ISS project leader Daniel Schubert from the DLR Institute of Space Systems in Bremen. “Now we are working on optimizing processes and procedures. We have learned a lot about operating a greenhouse under extreme conditions. We’re applying all this during the current joint DLR/NASA mission.” In addition to the crew’s time, the focus is on their well-being. The overwinterers regularly answer questions about their eating habits or how the plants affect their mood.  “We hope to increase our understanding of having plants and fresh food for crews in remote, isolated settings like Neumayer III and ultimately for space” says Wheeler.

Eight months in isolation

On 19 January, Jess Bunchek reached the Antarctic continent on board the research vessel Polarstern. Since 19 March, the 10-person overwintering crew has been on their own at Neumayer Station III. “EDEN ISS is an asset for the crew in many ways,” says Tim Heitland, Medical Coordinator and Operations Manager at AWI. “I know from my own overwintering experience just how much you can begin to miss fresh produce. It’s not just about the taste, but also the smells, the colors, and the fascinating fact that something can grow in this inhospitable environment. That’s why there are always volunteers in the overwintering teams to help cultivate and harvest the plants.”  The polar night at Neumayer Station III begins on 21 May, and the first rays of sunlight will not reach the station again until 23 July. Researchers for the summer season and new supplies will end the isolation of this year’s overwintering crew around the beginning of November.

The activities at the EDEN ISS Antarctic greenhouse can be followed on social media using the hashtag #MadeInAntarctica. The Antarctic greenhouse has Facebook and Instagram accounts, as well as a flicker image gallery. Jess Bunchek also writes about her personal experiences of the Antarctica mission in the dedicated DLR blog.

How The International Space Station Helps NASA Study Plant Growth In Space

As NASA plans long-duration missions to the Moon and Mars, a key factor is figuring out how to feed crews during their weeks, months, and even years in space.

Food for crews aboard the International Space Station is primarily prepackaged, requires regular resupply deliveries aboard cargo spacecraft, and degrades in quality and nutrition after about 18 months. But what if astronauts could grow some of their own food in microgravity? Researchers on Earth and crews aboard the International Space Station are exploring the idea by testing various crops and equipment to see if the plan could work.

NASA hopes to successfully grow fresh, pick-and-eat crops that are easy to produce and do not require a lot of extra equipment or precious electrical power. “Crews really seem to enjoy growing the food themselves,” said Howard Levine, chief scientist for NASA’s International Space Station Research Office at Kennedy Space Center in Florida. “It’s a nice reprieve from typical activities on the station, and astronauts often volunteer their free time to do it.”

To date, NASA has grown a variety of plants, including lettuces, mustard varieties, and radishes – and learned a lot about how to successfully do so in the process.

Here are seven aspects of plant growth they are studying aboard the space station:

1) Picking the right plants
What grows well on Earth may or may not do so well in space. Before sending a crop to space, scientists must identify which plants to test aboard the space station. To improve that process, NASA started a project in 2015 with the Fairchild Botanical Garden in Miami called “Growing Beyond Earth.” The program has recruited more than 230 middle and high school science classes across the U.S. to grow different seeds using special equipment. Seeds that grow well in the classrooms are then tested in a chamber at Kennedy that closely resembles the space station’s equipment. Selected seeds that do well at Kennedy are then sent to the station. How they grow in orbit can inform the selection of plants for long-duration missions only minimal crew attention.

2) Learning to garden in space
Plants need a place to grow, and NASA has tested out a number of facilities to host a microgravity garden. One way is by experimenting with the Vegetable Production System, or “Veggie,” which is a simple, low-power gardening chamber that can hold six crop plants. Seeds are grown in small fabric “pillows” placed in Veggie. Crews then look after and water the plants by hand, similar to caring for a window herb garden on Earth. 

NASA is developing another system, called the Passive Orbital Nutrient Delivery System, or PONDS, to work with the Veggie platform. PONDS replaces the seed pillows with a new plant holder that automatically feeds and waters the produce, but still requires the crew to do some cultivation tasks. Research also uses a hands-off system called the Advanced Plant Habitat. This fully automated device is designed to study the physiology of how plants grow in space in ways that require only minimal crew attention.

3) The right light
The composition of light that shines on plants can affect their size, nutritional content, microbial growth, and taste. Plants particularly rely on red and blue light to grow. Researchers ran experiments aboard the space station to see how different ratios of red and blue light influenced plant development in space. The experiments showed that plants in space grow well under the same light conditions preferred by plants on Earth. While green lights are not necessary for plant growth, they are included in plant growth systems so the plants also appear similar to those grown on Earth.

4) The influence of gravity 
Changes in gravity can affect how plants grow and how many crops they yield. Plants can sense gravity using a mechanism that involves changes to calcium within their cells. Astronauts recently ran experiments aboard the space station to measure how microgravity affects these calcium levels, which could offer clues for designing improved ways of growing crops for food in space.

In the PESTO experiment, crews grew wheat plants to see how microgravity may change some of their key features. They found that microgravity alters leaf development, plant cells, and the chloroplasts used in photosynthesis, but did not harm the plants overall -- in fact, wheat plants grew 10% taller compared to those on Earth.

Station crews also successfully grew two generations of mustard plants using the Advanced Astroculture chamber for an experiment that showed the change in gravity caused seeds to be smaller and secondary branches and seed pods to grow differently. Additionally, the experiment grew soybeans from seed-to-seed in space, which produced larger plants and seeds.

5) Water delivery
One significant challenge to growing plants in microgravity is providing enough water to their roots to keep them healthy without drowning the plants in too much water. Numerous experiments have tested a variety of methods to achieve this, including the new PONDS facility mentioned above and the Plant Water Management experiment. The water management study demonstrated a hydroponic method for providing water and air to the root zone to help them grow. Researchers are growing plants both aboard the space station and on Earth to compare how well they develop.

6) How old is too old?
Future space missions could go on for years, which means the seeds that astronauts bring along could be far from fresh by the time they need to plant them. On Earth, seeds have a decrease in viability and germination over time. But how do the age of seeds and long-term exposure to the spaceflight environment affect their ability to germinate and grow? To find out, in January 2021 NASA grew lettuce and seeds from the cabbage family (kale, mustard, and bok choi) that had been aboard the station for nearly three years. The results showed that while the lettuce seeds did not grow well compared to seeds that had been in space less time, the mustard seeds responded better than expected to the storage time in space.

7) The human effect
Gardens need tending, of course, which means astronauts or robots have to look after the plants that are growing. NASA studied how gardening in space could contribute to the behavior and well-being of astronauts. Many astronauts reported they found caring for the plants a fun and relaxing activity.

“Taking care of plants can also help astronauts stay in touch with the life cycles on Earth,” said Gioia Massa, a life sciences project scientist at Kennedy. Massa’s research focuses on growing plants aboard the space station.

What’s more, astronauts say the time spent gardening makes them excited to eat the fresh produce once it’s ready. The excitement motivates astronauts to creatively use the produce as ingredients in their meals, increasing their quality of life in space and boosting their morale.

A proposal conceptualized by an NSW architect for an international design competition that sought ideas for sustaining life on Mars has won the top prize.

Giuseppe Calabrese, the senior architect at Council Approval Group – a small Australian town planning and architecture firm – was placed first at the international competition launched by the Californian smart city development company, Mars City Design, and backed by NASA. The primary objective of the competition was to source ideas to sustain human life on Mars for more than two years.

Calabrese’s submission outlined how rockets would send robotic self-building farms a year prior to the first human landing. Using Artificial Intelligence and 3D printing, these buildings, preloaded with seeds, would then assemble autonomously and begin growing enough fruits and vegetables to sustain nine astronauts for up to two years.

Last month, Calabrese was shortlisted in the top 10 designs, competing against international firms from the USA, Germany, United Arab Emirates, and Taiwan. On the live-streamed awards night recently, his submission was announced as the winner for ‘Mars City Design Urban Farming Challenge 2020’, which was presented by NASA astronaut, Col. Terry Virts.

Until less than a year ago, Calabrese spent his time designing granny flats, duplexes and boarding houses for investors. Following the COVID pandemic, he was able to keep his job thanks to the Job Keeper program. During this period, he was also able to use his surplus design time on a passion project – town planning on Mars. When the competition came up, he decided to apply his architectural skills to the challenge.

Competition founder Vera Mulyani was very impressed with the Australian submission, not only for the visually appealing designs but also for the fact that every detail was supported by hundreds of pages of research and scientific data.

“Our next step is to secure funding, so we can build a prototype of the winning designs, which include Calabrese's proposal, in the Californian desert,” Mulyani added.

Calabrese’s smart farm idea couldn’t have come at a more perfect time given that NASA’s latest high-tech Rover will be reaching Mars in February 2021 while Elon Musk is considering a mission to the red planet as early as 2024.

“Australia already leads the world in many farming practices. So why not in space? And when billionaire Elon Musk needs an architect to design his mansion on Mars, he now knows who to call,” Calabrese said with a smile.

Abu Dhabi’s AgTech Ecosystem Expands Across Land, Sea And Space

•      ADIO partners with Pure Harvest Smart Farms, FreshToHome, and Nanoracks

•  AED 152 million (USD 41 million) incentives for ‘land, sea and space’ projects to increase AgTech capabilities for food production in arid and desert environments

• New partnerships part of ADIO’s AgTech Incentive Programme, established under Ghadan 21, Abu Dhabi’s accelerator program

Abu Dhabi, UAE – 10 November 2020: Three innovative agriculture companies will develop cutting-edge projects in Abu Dhabi to boost the emirate’s agriculture technology (AgTech) capabilities across land, sea, and space. The Abu Dhabi Investment Office (ADIO) announced today individual partnerships with Pure Harvest Smart Farms (Pure Harvest), FreshToHome, and Nanoracks that will see the companies receive financial and non-financial incentives totaling AED 152 million (USD 41 million). The research and technologies developed by these companies will expand existing capabilities in Abu Dhabi’s AgTech ecosystem and promote innovation in the sector to address global food security challenges.

The new partnerships are a continuation of ADIO’s efforts to accelerate the growth of Abu Dhabi’s AgTech ecosystem through the AgTech Incentive Programme, which was established under Ghadan 21, Abu Dhabi’s accelerator program. The Programme is open to both local and international AgTech companies. The partnerships follow ADIO’s AED 367 million (USD 100 million) investment earlier this year to bring four AgTech pioneers – AeroFarms, Madar Farms, RNZ, and Responsive Drip Irrigation (RDI) – to the emirate to develop next-generation agriculture solutions in arid and desert climates.

H.E. Dr. Tariq Bin Hendi, Director General of ADIO, said: “Abu Dhabi is pressing ahead at full steam with our mission to ‘turn the desert green’ and solve long-term global food security issues. We have created an environment where innovative ideas can flourish and this has enabled the rapid expansion of our AgTech sector. Innovations from the companies we partnered with earlier this year are already propelling the growth of Abu Dhabi’s 24,000 farms. Partnering with Pure Harvest, FreshToHome and Nanoracks adds a realm of new capabilities to the ecosystem across land, sea, and space.”

Bin Hendi continued: “We are driving innovation across the entire agriculture value chain and this is producing a compounding effect that is benefiting farmers, innovators, and companies in our region and beyond.”

Pure Harvest, FreshToHome, and Nanoracks have been awarded financial and non-financial incentives to expand operations in Abu Dhabi. The competitive incentive packages include rebates on innovation-linked high-skilled payroll, high-tech CAPEX, as well as land, utility, and intellectual property support. 

Since the beginning of 2020, ADIO has attracted seven AgTech companies to Abu Dhabi, each bringing a complementary skill to expand the ecosystem. ADIO’s new partnerships with Pure Harvest, FreshToHome, and Nanoracks will build on the achievements made by AeroFarms, Madar Farms, RNZ, and RDI, the AgTech pioneers ADIO partnered with earlier this year to establish R&D and production facilities in Abu Dhabi.

Partnerships with Pure Harvest, FreshToHome, Nanoracks

Pure Harvest is a home-grown, tech-enabled farming venture that uses cutting-edge food production systems to grow fresh fruits and vegetables in a climate-controlled environment, enabling year-round production anywhere, while using seven times less water compared to traditional farming methods. Pure Harvest will invest in smart farming and infrastructure technologies at its new farms in Al Ain, Abu Dhabi, to optimize growing conditions through hardware design innovations, artificial intelligence, autonomous growing and robotics, plant science research, and desert-optimized machines. The company will also progress R&D and deployment of a commercial-scale algae bioreactor production facility that will grow higher quality, healthier Omega-3 fatty acids without the limitations and challenges of traditional animal sources.

Allen Herbert, SVP of Business Development and Strategy, and Head of Nanoracks, UAE, said: “Much of today’s technology used for vertical, urban and closed environment agriculture initially came from space research from 30 years ago, and Nanoracks is ready to synergize these technologies back to in-space exploration. We firmly believe that space research holds the keys to solving major challenges on Earth from climate change to food security. And our StarLab Space Farming Center in Abu Dhabi is just the beginning. We’re building a global research and development team that will produce and commercialize organisms, technology, and innovative products that will not only revolutionize farming in Earth’s deserts and harsh environments but also change the way humans are able to explore deeper into our universe.”

How A Winnipeg Company Wants To Change Agriculture

Here are some other interesting tidbits about Conviron. Founded in 1964 by the Kroft family, CEL Group of Companies is headquartered in Winnipeg, MB. CEL comprises Conviron Canada, USA and Australasia. It also includes Argus Controls, a supplier of plant-centric environmental controls and automation systems used in greenhouse and indoor growing facilities. 

Conviron has provided plant growth chambers and technology to the top government research agencies, universities and AgBiotech companies in over 90 countries around the world.

CEO Steve Kroft, often refers to his company’s solutions as 'weather in a box' because they mimic outside conditions and changing seasons over time through the automated control of temperature, light, humidity, irrigation and nutrients. In effect, it's a specialized type of high-tech greenhouse or indoor farm with environmental factors that can be precisely controlled.

Researchers at University College Dublin in Ireland can reconstruct prehistoric atmospheres using Conviron chambers and investigate plant evolution throughout Earth's history.

When canola was first developed in the 1970s, part of the research was done in Conviron chambers. Canola is the world’s only “Made in Canada” crop. In response to the ban of trans-fatty acids in food products, canola was developed by researchers from Agriculture and Agri-Food Canada and the University of Manitoba in the 1970s, using traditional plant-breeding techniques.

The Indoor Farm Revolution

Coronavirus chaos has spurred a grow-your-own food movement — and space-age hydroponic technology is rising to meet it.

View fullsize

By Chris Taylor

NOTE FOR 2020 READERS: This is the eleventh in a series of open letters to the next century, now just 80 years away. The series asks: What will the world look like at the other end of our kids' lives?

Dear 22nd Century,

For all the pain, grief and economic hardship the 2020 coronavirus pandemic has sown, a handful of green shoots seem to have taken root in its blighted soil.

Green being the operative word, because many of these developments could be a net positive for the planet. In lockdown, many of us are seeing what our cities look like without smog. Office workers are experiencing office life without the office; just last week, Twitter announced that most of its employees could work from home forever, while much of Manhattan is reportedly freaking out about what could happen to commercial real estate. Thousands of companies just discovered they can still function, and maybe even function better, when they don’t chain employees to desks or force them to make a soul-crushing, carbon-spewing commute 10 times a week.

And what do more people do when they’re spending more time at home? Well, if you’re like my wife, you start literally planting green shoots. Our house is filling up with them as I write this: lettuce, chard, tomatoes, basil, strawberries, to name the first five shoots poking out of dozens of mason jars now taking up residence on every windowsill. She’s hardly alone; garden centers and seed delivery services are reporting as much as 10 times more sales since the pandemic began. Even the mighty Wal-Mart has sold out of seeds. If viral Facebook posts and Instagram hashtags are any guide, pandemic hipsters have moved on from once-fashionable sourdough starters to growing fresh fruit and veg. 

Another one of our cyclical “back to the land” movements seems to be underway, just like during the 1960s and the Great Depression before that. Only this time, we don’t need land. We don’t need soil. We don’t need pesticide of any kind. We don’t even need natural light. Thanks to giant leaps forward in the science of hydroponics and LED lighting, even people in windowless, gardenless apartments can participate in the revolution. With a number of high-tech consumer products on the way, the process can be automated for those of us without green thumbs. 

In previous letters I’ve discussed the inevitable rise of alternative meat, a process that has been accelerated by the pandemic. I talked about the smaller, more nutritious plant-based meals we're going to need for life extension; I assumed such meals would be delivered by drone. But now I see a future with no food deserts, in which every home is filled with rotating space-station-like hydroponics run by artificial intelligence — a cornucopia of push-button farming providing the side salad to your plant-based meat. 

Even if you don’t grow your own, robot-run vertical farms and community “agrihoods,” now springing up everywhere, will make amazing-tasting produce abundant and cheap. The “locavores” of our era like to boast about their 100-mile diet. Yours will look more like a 100-yard diet. 

Green, not soylent 

It’s worth remembering that it wasn’t supposed to be this way. The 2020s, in fact, is when we were slated for starvation, food riots, and big business quietly processing our corpses into food. 

That’s the plot of the 1973 movie Soylent Green, set in the year 2022. Fruit and veg have all but vanished. In one scene, Charlton Heston's detective hero smuggles home a single tomato and a wilted stick of celery, enough to reduce his roommate Sol (Edward G. Robinson) to tears. On the other end of the future, in a lighter but equally depressing vein, the 2006 comedy Idiocracy showed the Americans of 2500 running out of crops because they couldn’t figure out that water, not "Brawndo" (a spoof on colorful sports drinks), is “what plants crave.”

But these dismal future visions are receding thanks to the science of hydroponics — which dates back to the 19th century, no matter its present-day association with growing marijuana. By the 1930s, we’d figured out that what plants crave is surprisingly minimal: nitrogen, a handful of minerals, something to anchor the roots like rock wool or coconut husks, and H2O. Early hydroponic farms helped feed U.S. soldiers as they hopped through the Pacific during World War II.

Minimalist methods multiplied, and are still multiplying. We’re tweaking the spectrum of LED lights for maximum growth, and figuring out ways to use progressively less water and nutrients. My wife’s mason jar seedlings use something called the Kratky method, where you don't even need to change the water. It turns out this method was invented by a Hawaiian scientist as recently as 2009. And it’s the closest science has yet given us to a free lunch.

Reinventing the wheel

I’m nowhere near as excited by hydroponics as my wife is. But during our quarantine time, even my head has been turned — by the Rotofarm, which I’ve come to think of as the iPhone of gardening. It’s a beautiful device inspired by NASA research on growing plants in space. It uses anti-gravity — literally, when the wheel rotates around its LED light source and the plants are hanging upside down — to grow plants faster. A magnetic cover reduces the glare and increases the internal humidity. You manage it via an app.

Humankind’s oldest technology turns out to be the most efficient use of space for growing plants; even in this 15-inch-wide wheel, you can really pack them in. At the bottom of the wheel, plants dip their roots into the water and nutrient tanks. An owner’s only job is to refill the tanks every week or so, and to snip off their dinner with scissors a few weeks after germination. Some leafy greens, like my favorite salad base arugula, can be regrown without replanting.

Still, to be fully self-sufficient, a future apartment is going to need to have multiple Rotofarm-style devices on the go at once — but they’re designed to live anywhere you can plug in, on coffee tables, on desks, on walls, as eye-catching as artwork.

The main problem with the Rotofarm: It isn’t actually on sale yet. “It feels like we’ve done everything in reverse,” Rotofarm creator Toby Farmer said when I reached him via video chat from his home in Melbourne. “We’ve got the patents, we’ve got the design awards, we’ve got the customers. Now we need to finish the prototypes.” (One key tweak: reducing Rotofarm’s energy requirements, which as it stands could double many users’ household electricity bills.)

Still, orders have come from as far afield as Japan and the Netherlands, from retailers and regular users alike. Farmer’s biggest regret: When Ron Howard’s production company called, hoping to use eight Rotofarms in an upcoming Nickelodeon show set in space, Farmer didn’t have enough to spare.

Rotofarm has been in the works for a few years, but a crowdfunded Indiegogo campaign that closed last month exceeded its $15,000 goal by a third of a million dollars. Farmer, despite his name, had no experience in this area; just 23 years old, he had been a web designer since the age of 12. But he’s scaling up fast, hiring teams in LA and Singapore, soaking up their knowledge (he was keen to assure me he’d hired a lot of 40-somethings for this very reason).

After a projected 2021 release date, Rotofarm’s business model involves making money on proprietary seed pods — though Farmer admits that “there’s a DIY aspect” where customers can make their own. His hope is that official Rotofarm pods will be competitive because they’ll have fewer germination failures, but he'd rather see a world where more people own the device itself. In that spirit, he’s making it modular — the LED light bar can be upgraded separately, for example, rather than making customers buy a whole new device. (As for cost, Farmer says he can't comment yet — though Indiegogo backers were able to secure one for $900 a pop.) 

Might the Rotofarm fail? Of course, just like any other crowdfunded project. Much depends on its price point, as yet unannounced. But it’s far from the only next-level, set-it-and-forget-it hydroponic station taking aim at your kitchen. There’s a Canadian Kickstarter called OGarden that also grows food on a wheel, albeit a much larger wheel. The OGarden was funded in its first six minutes online and is set to cost around $1,000 per unit. There’s Farmshelf, a $4,900 pre-order hydroponic device that looks like a see-through refrigerator, backed by celebrity chef Jose Andres. Users will pay a $35 monthly subscription to get all the seeds they need. 

One of these models is the future; maybe all of them are. Right now, these are high-end devices aimed at early adopters (and restaurants, which get a lot of benefit out of showing off how fresh their produce is as customers walk-in). But with scale, with time, and with the growing desire for grow-your-own food that Rotofarm and its brethren have revealed, they will get cheaper and more widespread. 

After all, the first Motorola cellphone, in 1983, cost $4,000. It looked like a brick and had 30 minutes of talk time. Now sleek, supercomputer-driven smartphones are accessible to pretty much everyone. The same process will happen in-home hydroponics. 

Rise of the vertical farm

Give it 80 years, and I can see apartments with built-in hydroponic farms provided as a standard utility, much as a fridge is seen as a standard feature today. As more humans move to urban environments — two out of every three people will be in cities by 2050, according to the latest UN estimate — the need for such devices will only grow.

“We strongly believe the future of gardening is indoor gardening and more individual gardens,” OGarden CEO Pierre Nibart told us last year. “Stopping mass agriculture and starting to produce their own little stuff at home.” He said this while demonstrating his family's daily OGarden routine: His kids harvest most of what they need for dinner from the spinning wheel. 

Mass agriculture hasn’t exactly covered itself in glory where produce is concerned. And in the post-coronavirus age, we are surely going to become less tolerant of the disease its intensive farming methods have caused.

Food poisoning caused by romaine lettuce, which makes up a quarter of all leafy greens sold in the U.S., has become depressingly familiar. The 2018 E Coli outbreak was the worst — it sickened 240 people in 37 states, hospitalized almost half of them, and killed five. But the CDC has logged 46 E Coli outbreaks since 2006 and says that every reported case of infection is likely matched by 26 unreported ones. And they’re only just starting to figure out the most likely cause: groundwater contaminated by nearby cattle manure. There could also be an infection from passing birds, another major vector of bacteria. 

Never mind the wet markets of Wuhan that likely caused the coronavirus pandemic. We’re already sickening ourselves on the regular with a problem that is baked directly into our food system — and it’s affecting vegans as much as meat-eaters. 

I have no doubt you’ll look at our barbaric farming methods and shake your heads. Why did they use so much water? Why did they transport produce an average of 1,500 miles? Why did they grow it outdoors, where it’s vulnerable to pests, and then use pesticides that had to be washed off? Why did they think “triple washing” did anything to remove bacteria (it doesn’t)? Why did they bother using soil, for goodness’ sake? Didn’t they know what plants crave?

The force of legacy agriculture is strong, but an increasing number of companies are figuring out a better way: the vertical farm, so named because they can stack hydroponic produce in shelves or towers. As I write this, there are more than 20 vertical farm operations being constructed and tested around the country. They use around 90 percent less water than regular soil farms, can grow roughly 10 times more food per acre than regular soil farms, and using precision software they can harvest their produce 30 percent faster than regular soil farms. 

Sure, they’re spending more on electricity, but they’re also spending nothing on pesticide. The economics seem irresistible.

Last year, less than 20 miles from where I write this, in highly urbanized South San Francisco, a company called Plenty unveiled its flagship operation, a vast vertical farm named Tigris. Its sheer scale invites the correct usage of California’s favorite word, “awesome.” Tigris can grow a million plants at once, harvesting 200 of them every minute. With $226 million in funding, Plenty says it has already farmed 700 varieties of produce. Right now, the cost to consumers is comparable to non-hydroponic products (I can get their baby arugula at my nearest Safeway for a dollar an ounce); in the long run, it should be cheaper.

And they are far from the only success story. A Chinese startup, Alesca Life, is turning disused parking lots into vertical farms as well as selling plug-and-play shipping container farms. Back in Silicon Valley, a company called Iron Ox is developing robot arms for indoor farmwork. The future looks green and bountiful, and mostly automated (which is yet another reason you’re going to need Universal Basic Income).

Fresh future: Inside Plenty's vast vertical farm in South San Francisco.PLENTY

Which is not to say that outdoor agriculture is going away completely; it’s just going to shrink to the size of a community garden. That’s the basis of new urban developments called “agrihoods,” or multi-home communities centered around a professionally managed farm; a just-published book called Welcome to the Agrihood represents their first directory. 

Rooftop organic farms, urban allotments: These are places where city dwellers can connect to the land and feel the satisfaction of nurturing their seeds from scratch. Soil may not be necessary to feed us, but sometimes it’s good to feel the dirt in your fingers. Similarly, farmer's markets are unlikely to go away. In a world where grocery stores are increasingly becoming delivery centers for services like Instacart, there will still be value in meeting and buying direct from the growers of high-end produce. 

With big agribusiness heading indoors, with our apartments growing much of what we need and vertical farms providing backup in every city, we’ll also be able to let most of our present-day farmland go fallow. That in itself should take care of a chunk of climate change, considering the amount of carbon-soaking vegetation that springs up on fallow land. Lab-grown and plant-made meat will remove the need for those disease-ridden feedlots. Aquaponics, another discipline where the science is expanding by leaps and bounds, may even let us grow our own fish for food, reducing the strain on our overfished oceans.

No doubt it won’t be all smooth sailing. No doubt we, as humans, will stumble upon fresh ways to mess up the planet and make life worse. But from where I’m sitting, surrounded by soilless germinating jars, the future looks very green and nutritious indeed.

Yours in leafy goodness,

2020

The Best Growing Mediums For Microgreens

View fullsize

Growing microgreens is an easy and sustainable process that you can do from the comfort of your home. You can grow all kinds of nutritious microgreens that will enhance the flavor of your foods. These special vegetable-like plants grow from 1-3 inches and are vibrant additions to your foods. They are also jam-packed with vitamins and antioxidants. We're going to discuss the different growing mediums you can use for your microgreens.

Soil

Using soil as your growing medium is a popular and effective choice. Soil will provide you with the best yields over any other medium. We believe the Sunshine #4 by Sunshine Aggregate is the best, and the Black Gold Potting Mix is a close second. Each of these soils are extremely sterile, which is ideal for indoor growing. While these soils can cost more (about $1 per 10x20 tray), they provide the best results. But, don't worry. You can compost and sterilize your soil to re-use it for future grows.

View fullsize

Burlap

Burlap is another popular growing medium because it's cheap. For .25 cents a tray, you can't beat the price. It is made from the jute plant, which is used to make nets and ropes. But burlap is an incredibly difficult growing medium to use. The perfect growing conditions for burlap include 72 degrees Fahrenheit, 65% humidity, and a good micro-dose fertigation plan (fertilizer + irrigation). If you can populate these results, then you can achieve yields and results that match soil mixes.

But be mindful that this takes a lot of practice and time, which is why using burlap is better for expert growers. If you don't get the growing conditions right, then your yields will suffer. We recommend using larger seeds like Pea Shoots and Wheatgrass when using burlap. These seeds will thrive with a burlap growing medium, and you will get bountiful results.

Coco Coir

This growing medium comes from coconut fiber. It's perfect for holding in moisture and is difficult to over-water. It is cheaper than soil (about .60 cents a tray), but it's just as messy. Coco coir has a better yield average than burlap, about a 25% to 30% better average. You will find this growing medium in dehydrated blocks. When you add water, they will expand way past their original size. You can use coco coir with an ebb and flow hydroponic method.

Jute Pads

View fullsize

This growing medium is derived from jute fiber. It's able to transport water evenly through your microgreens and maintain a near-perfect water/air ratio. It holds in water very well, which means you'll have to feed your microgreens less. Kale and broccoli grow especially well in jute pads.

What's the Best Growing Medium?

This entirely depends on your growing intentions. What are you planning to grow and how much effort are you willing to put in? We're going to cover the main questions you should ask yourself that will help you make this decision.

• Feeding Your Plants: If you want to water your plants by hand, then we recommend soil and coco coir. But if you're able to feed your plants on a timer, then go for burlap or jute pads. It can be a better option because it's cost-effective and can still get the job done.

• Choosing Your Seeds: What kind of microgreens do you plan to grow? If you're growing broccoli or kale, then we recommend buying jute pads. Do you want to grow a wide variety of seeds? Then choose soil or coco coir as your growing medium.

• Messy Vs. Clean: Do you hate cleaning up messes? Then it's best to steer clear of soil and coco coir. Go with jute pads since they're easy to handle and clean.

Choosing your growing medium ultimately boils down to what you're planning on growing and how much effort you want to exert. We hope this list helped you understand what kinds of growing mediums there are and how they can help you yield the best results.

We are the microgreen growing experts. We're even working with NASA to help figure out how to get microgreens safely into space for astronauts to use! We meet once a month to discuss a variety of topics about microgreens. So, keep reading our blogs and watching our informative YouTube videos. There will always be exciting news coming your way.

Purdue University Mechanical Engineering Technology Grad Developing Food Technology For NASA’s Mars Missions

A graduate student who gained experience growing plants for a Purdue Polytechnic research project is now helping NASA develop microgravity food production technology to sustain astronauts during long missions to Mars.

Jacob Torres graduated from Purdue in May 2018 with a master’s degree in mechanical engineering technology. During his studies, he worked on the Biowall, an eco-friendly air filtration system that can be used in residential buildings to improve air quality. That experience proved beneficial when he applied for an internship at Kennedy Space Center in Merritt Island, Florida.

“I did the application and never thought I’d hear anything back from them, straight up,” said Torres. “On the application, there just happened to be one line that said, ‘plant growth for food production in microgravity.’ I thought that was pretty cool and in my research at Purdue, I made a biowall, and it uses plants to filter indoor air.”

After that 10-week internship, NASA (the National Aeronautics and Space Administration) invited Torres to continue his work for an additional four months. In December 2018, his position as a technical and horticultural scientist became permanent.

Torres’ path to becoming a research scientist at NASA has been anything but traditional. He moved from New Mexico to Las Vegas immediately after graduating from high school, found a job at a restaurant and worked his way into a management position. A chance encounter with actors Bill Murray and Billy Crystal led to several years as manager of three of Murray’s restaurants in South Carolina and Florida.

“It was such a rough ride,” said Torres. “I told myself I couldn’t run restaurants for the rest of my life. I was like, ‘Is this all I have to do, is this as far as I could go?’ No way.”

NASA: First Fruit Grown In Space To Spice-Up Astronauts' Menu

View fullsize

Researchers at NASA are planning on sending a version of chile peppers in space to be grown and harvested at the International Space Station. The peppers, from Española in New Mexico, would be the first fruiting plant to be grown in space once it is sent to the ISS for testing in March 2020. The tests are a part of NASA's major plan to produce food outside Earth's atmosphere.

NASA researcher Jacob Torres, has stated that the point of the mission is to see if NASA's Advanced Plant Habitat-a bioscience research facility at ISS that recreates a plant's environmental needs (CO2, humidity, etc.) can grow fruiting crops. NASA has already successfully grown leafy crops at ISS.

Why a pepper?
The obvious question is, if you're sending a fruiting plant, why not send something more appetizing than a pepper? The answer is that not every crop can successfully grow in space and the Española Chile Pepper could just help pave the way for interstellar farming. The plant has already met NASA's needs for easily pollination and the ability to survive in high CO2 environments.

The Farms of The Future Were Built For Outer Space. Will They Work On Earth?

On Mars, we'll all farm underground. Our crops will grow in a greenhouse, where large, parabolic mirrors focus the sun's weak rays and transmit them through fiber optic cables. We'll harvest vegetables to eat—but also the purified water that evaporates from their leaves. We'll all be vegan, because raising animals for food will be too expensive. And, most importantly, the plants will give us oxygen.

"That's the starting point to a whole civilization right there," says Utah State University researcher Bruce Bugbee. This is Bugbee's vision, one he's been dreaming of and testing and revising for years as a plant engineer with NASA.

Astronauts going to Mars can eat all the freeze-dried food they're able to ship, but if humans are going to survive on the planet they'll need to plants to produce oxygen. Not just any photosynthesizer will do: Mars is a difficult environment, with many challenges for farmers. Crops will need to be able to thrive in a small area, retain their nutrient content, and still taste good. Structures where they grow on the surface will need to withstand basketball-sized meteorites. The technology used to grow the plants will take massive amounts of energy. Mars also presents the ultimate recycling challenge, since astronauts can't pack all the water and nutrients they need on a two-and-a-half-year space flight.

Bugbee and his colleagues have been working on all these problems for decades, in a sometimes fantastical bid to support life on Mars (and, in the meantime, on space shuttles). Decades ago, NASA researchers ruled out some of the easiest plants to grow indoors, like algae: not enough sustenance, Bugbee says. Very tall crops like corn and sugarcane were also nixed because they wouldn't fit easily into the plant habitats.

What the astronauts really wanted was something green. "They say that having the texture and flavor and color and aromas of fresh foods apparently—and I believe it—really does add to the experience of eating," says NASA plant physiologist Raymond Wheeler.

Scientists started looking at traditional field crops like lettuce, tomatoes, and broccoli. Right now, astronauts are growing mixed greens 250 miles above Earth on the International Space Station, using two small, sealed greenhouse units called Veggie. NASA researchers have planned and adjusted and measured for everything—including which types of lettuce tastes best in space. Astronauts' clogged sinuses already make it so they "can't taste much of anything," according to Canadian astronaut Chris Hadfield, but the researchers are also curious to see whether the space environment affects a plant's flavor compounds and nutrient levels. Panels of specialists at NASA's Johnson Space Center in Houston typically conduct formal taste tests, but sometimes the researchers sample a leaf or two themselves.

What Bugbee and his team didn't expect is that the technology they created for this grandiose, futuristic mission would become somewhat eclipsed by those using it to farm on more familiar terrain.

In 2017, NASA commissioned a space farming project to figure out how to grow food on Mars, but they were also hoping to make some discoveries that could improve crop yields overall. The problems that space farmers of the future will face are similar to those already plaguing earthbound agriculture as climate change grows worse, including a dwindling water supply and poor soil. Now, researchers in Utah and three California universities—NASA's partners with the Center for the Utilization of Biological Engineering in Space—are working on projects that can sustain life not just on Mars, but on Earth.

"I think the reason NASA funds us is a powerful human fascination with being able to go inside a closed system and grow your own food," Bugbee says. "What if the atmosphere went bad and we had to build a big dome ... and go inside and live in it?"

In 1988, Wheeler built the first working vertical farm—growing plants on shelves, typically in a warehouse or storage container—at the agency's Kennedy Space Center. Wheeler's farm was 25 feet high and equipped with a hydroponic system for growing plants in water and high-pressure sodium lamps, the type commonly used for street lighting. All together, it was 20 square meters of growing space—almost 90,000 times less than the size of the average outdoor United States farm. According to Wheeler's calculations, it would take 50 square meters of plants to provide enough food and oxygen—and remove enough carbon dioxide—for one human in space. (Astronauts won't be using sodium lamps, though: A few years after Wheeler's innovation, a different group of NASA-funded researchers patented another significant piece of technology to indoor farmers: LEDs, which require much less electricity than sodium lights and are now used to power most greenhouses.)

Wheeler was focused on optimizing the area inside a chamber aboard a NASA space shuttle—and up seemed like the best way to go. "One of the things you have to think about in space is volume efficiency," he says. "You're vertically and dimensionally constrained." The team had to pick shorter crops: wheat, soybeans, potatoes, lettuce, and tomatoes.

In space, resources are limited: NASA scientists have to extract and reuse the nutrients from excess plant material and human waste; they collect water from the condensation that collects in the closed chambers. Here on Earth, water is also growing increasingly precious—climate change will make droughts more frequent and severe, devastating crop yields and making some staple crops like corn and soybeans obsolete. Every day, Earth looks a little more desolate, a little more like Mars.

When Wheeler started, the term "vertical farming" didn't exist yet. Today it's a $10 billion industry attracting interest from Silicon Valley and start-ups all over the world. Its acolytes believe the technology will one day completely replace conventional field agriculture, allowing businesses to grow crops year-round and indoors, insulated from the next drought or flood and the effects of climate change. "People imagine that we'll grow everything indoors, in skyscrapers in the middle of Manhattan," Bugbee says. "It's a wildly popular idea."

Sonio Lo, the chief executive officer of the biggest vertical farming company in the world, Crop One Holdings, says she believes vertical farming can "liberate agriculture from climate change and geography."

Crop One broke ground on the world's largest vertical farm last November in Dubai: a five-story, 130,000-square-feet warehouse, capable of producing three tons of leafy greens a day. The company is also growing chard, arugula, and other greens in large, sealed rooms—year-round. "I made my whole management team stand in the supermarket and give out samples of what we were growing in the middle of the Boston winter," Lo says.

Soon people across the U.S. can try it too. Crop One is building new farms in the northeast, southwest, and California, where it will grow food to sell through its FreshBox Farms brand.

While researchers have been quick to condemn vertical farming's promises as over-hyped, even the industry's greatest critics acknowledge that this approach eliminates some of the challenges with conventional agriculture: Since vertical farms are located in compact warehouses, they're often located much closer to their markets than, say, the corn belt is to a city, allowing producers to cut down on food waste and save on transportation costs—a major contributor to U.S. greenhouse gas emissions.

The lettuce grows in a controlled environment, free of pests and pathogens, meaning farmers can grow food without pesticides or herbicides, which have a massive environmental and human-health cost. Vertical farmers can also recycle their nutrients—like astronauts do in space—preventing phosphorus or nitrogen from flooding into the world's waterways and wreaking havoc with algal blooms. And indoor growth systems can be very productive: When all the conditions are right, researchers have surpassed record crop yields in the field by as much as six times.

Lo says that a vertical farm using 100 percent renewables has one-tenth of the carbon impact of a conventional farm. But few companies have reached this goal; most are still moving toward a combination of renewable energy and non-renewables to power the electric lights used to grow the plants. It takes a lot of land to generate that much solar—about five acres of solar panels to supply the light for just one acre of indoor farm, Bugbee estimates. That's why many have resorted to fossil fuels, breaking one of vertical farming's great promises. "It takes massive amounts of fossil fuel energy, so, environmentally, it's really a disaster," Bugbee says. "Those people have used many of the principles that we've developed through NASA."

Bugbee's current project could help with that. His lab at Utah State is using LEDs and fiber optics to grow plants under different types of lights, with different ratios of colors—ultra violet, blue, green, red, far red (out of the limit of human vision)—to manipulate both photosynthesis and plant shape. The goal, he says, is to find "the most efficient system possible." Right now, the technology is too expensive: millions of dollars to light one building. But eventually, he believes fiber optics will replace electric lights for good.

But there are other qualms with vertical farming: Instead of helping to colonize space—the future that Mars researchers envision for their technology—vertical farms might take over city real estate, at a time when housing costs are extremely high. In some countries and some industries, it already has: Japan has had flourishing plant factories for the last 10 years. The fledgling cannabis industry has also started to ramp up its indoor production, poised to become even more profitable.

Lo says it won't be long until greens grown indoors cost the same as those in the field. "Field-grown food will continue to rise in cost, and course the climate is also changing," she says. "From a cost perspective, vertical farming will become competitive very quickly."

Others are more skeptical: "Economically, will they succeed? That question is still ongoing, because they always have to compete with field agriculture," Wheeler says. "What's their cost to pay for electric power? What are their labor costs? Are these operations sustainable? All of this is sort of a living experiment right now."

Technology for farming in climate change may be a by-product of NASA's research, but it has helped the agency ensure funding for its work in space. In response to the skeptic who doubts whether it's worth figuring out how to farm for a Mars mission we might never see, one only has to point to vertical farms in Boston or Seattle that already use some of NASA's innovations.

But Bugbee believes these earthly pursuits can be just as futuristic (or deluded) as those meant for space. "People that do it say they're going to save the planet ... but they have to have a lot of fossil fuels," he says. "It'll tell you all kinds of rosy pictures about it—that it saves water, it saves fertilizer."

He's not quite comfortable with his research being used to prop up this industry, now flooded with billions of dollars of venture capital. "I'm not doing it to make this more possible on Earth," he says. "We get asked all the time about the spinoffs: Could you do this, could you do that."

We may never make it to Mars. It will be years until NASA is ready for a journey to the red planet, and many more until Bugbee would be able to build his greenhouse underground, tucked away from meteorites. But if Earth continues on this collision course, Mars could come to us.

As the 50th anniversary of Apollo 11's first Lunar landing and moonwalk on 20 July 1969 is observed this year, it is fitting to recall the myriad innovation spinoffs that NASA's space program had gifted mankind, ranging from the integrated circuit to computer microchips to satellite television to cordless tools to electric vehicles to freeze-dried food to memory foam, etc. -- and yes, still unbeknown to many, vertical farming.

The author's NASA-sponsored project on design and demonstration of NASA’s first Hybrid Solar and Electric Lighting System for Bioregenerative Space Life Support for application in future long-duration manned missions to the Moon and Mars.

While the Apollo program itself did not initiate or develop space farming, its unprecedented success directly led NASA to establish around 1978 the Controlled Ecological Life Support System (CELSS) division within its Advanced Life Support program with the aim in part of developing the technologies and strategies necessary to grow food and regenerate resources on the Lunar surface or on Mars for future long-duration manned missions and habitation.

Nearly two decades before NASA, however, the then Soviet Space program commenced activities beginning in 1961 toward developing its own bioregenerative space life support system. In 1968, the Soviets first realized growing crops in their completely sealed controlled-environment system Bios-2, located in the Siberian city of Krasnoyarsk, wherein they successfully cultivated wheat, carrots, cucumber, dill and other vegetable crops. (Bios-2 should not be confused with Biosphere 2 in Arizona which was constructed much later between 1987 and 1991.) An improved underground test facility, Bios-3, was subsequently built by the Soviets in 1972.

Fast forward to the 1980's and 1990's, NASA's CELSS program made significant advances in the cultivation of a whole range of crops in closed controlled-environment systems under optimized environmental conditions of lighting, temperature, relative humidity, air flow, nutrient compositions, etc.

The foregoing advances by both NASA and the Soviet Space program paved the way for the emergence of the first commercial vertical farms (or plant factories) in the United States and Japan. General Electric's Geniponics based in New York and Alaska as well as General Mills' Phytofarms of America in Illinois were established in the 1970's and operated through the 1980's, though eventually closing down owing to economic challenges.

It was in Japan in the 1980's, however, when the then fledgling vertical farming industry truly took root and flourished in part through their proactive adoption and incorporation of emerging technology innovations. For instance, TS Farm (Q.P. Corporation) was first in employing aeroponic systems, while Cosmo Plant Co. Ltd. in 2000 became the world's first commercial LED-based vertical farm and began producing up to 7,000 heads of lettuce per day, significantly exceeding the industry norm of 3,000 to 5,000 heads of lettuce per day in the 1990's.

Vertical farming today, of course, has gone global and, in parallel with advances in lighting technologies, climate control, data analytics, automation and other innovations, has correspondingly been setting new achievements in both yield and resource sustainability.

And just as the space program spun off the Vertical Farming industry, there is poetic symmetry in the very real prospects that it will be the vertical farming industry that will ultimately enable NASA, as well as other space programs, to develop and fully realize its bioregenerative space life support systems for future Lunar and Martian human habitats.

Just as Elon Musk's Space X, Jeff Bezos' Blue Origin and Richard Branson's Virgin Galactic have partnered with NASA to innovate on and advance space transportation, it is highly likely that partnerships with NASA for the design and operation of its future Lunar and Martian space farms will be brokered with the likes of AeroFarms, Plenty, Bowery Farming, CropOne Holdings, Gotham Greens, Infarm, AEssense and/or other vertical farming companies, some of which have yet to be formed.

In the future the vertical farming industry may indeed extend its prospects from the mere terrestrial to the extraterrestrial.

NASA Project Proves The New Mexico Chile Is Out of This World

A team of scientists at NASA is working to launch the Española chile pepper into space. This would be the first fruiting plant the United States has grown and harvested at the International Space Station.

One of the issues over long-term space missions is how to supply the needed food for the trip. Free-dried food can take up a lot of space and weight on an extended voyage and won't be that tasty. Back in the early 2000s,

NASA began exploring ways to supplement astronauts’ diets with plants that can be grown in space or on other worlds.NASA began by experimenting with growing seeds in simulated space environments here on Earth. With improved technologies, NASA is now learning to grow vegetables and fruits on the International Space Station (ISS). But it's not easy growing plants with less gravity than is found on Earth.

Seeds tend to move around in zero-gravity and water clumps up. Remember, you can't pour a glass of water in space. There is also the need to be frugal when it comes to space - we mean the size of the garden

Differences in lighting, temperature and even the medium used to grow the seeds had to be tested. And because of the weight of soil, NASA has been looking at methods like hydroponics and aeroponics. Hydroponics involves delivering water and nutrients to plant roots using liquid solutions, and with aeroponics, plants are grown in a misty air environment.

The first edible veggie is grown in space

The first portable growing box for space, equipped with LED lights, called Veggie, was tested at the orbiting outpost in 2014. After a few problems were worked out, astronauts got their first taste of NASA-approved space-grown lettuce in 2015. Now, there are two Veggie boxes and a third called the Advanced Plant Habitat.

Since NASA's first attempts using the Veggie, a number of green leafy vegetables, as well as zinnias and a sunflower, have been grown successfully on the ISS. In 2018 the Veggie-3 experiment was tested with plant pillows and root mats. One of the goals is to grow food for crew consumption. Crops tested at this time include cabbage, lettuce, and mizuna.

Today, fruits and vegetables that can be safely stored at room temperature are eaten on space flights. Astronauts also have a greater variety of main courses to choose from, and many request personalized menus from lists of available foods including items like fruit salad and spaghetti.

But even with all the variety of foods available for bringing on board the ISS, there is still the need for growing vegetables and fruits on space flights. And now that we are getting good at growing green, leafy vegetables, it was time to experiment with growing a fruiting plant.

The New Mexico Chile

Jacob Torres is part of a team of 20 people at NASA in Florida, working on a way to grow vegetables on board the ISS. Torres is originally from the Espanola Valley in New Mexico. When Torres arrived at NASA in 2018 for an internship, scientists were exploring the possibility of growing Hatch peppers, a New Mexico chile.

Torres suggested that NASA look at the state's Española pepper instead. There was a good reason for the suggestion. Hatch peppers are grown in the deserts of New Mexico, while the Española pepper grows at higher elevations and has a shorter growth period. Tosses thought they would be better for growing in space.

After experimenting with growing the Española peppers here on Earth under simulated space conditions, the little peppers are ready to be sent off to the ISS sometime between November and January 2020. If successful, the Española pepper would be the first fruiting plant - a flowering plant that grows a seed pod to procreate -- to be grown at the International Space Station

.“What an honor, what a privilege, and what a great way to represent the Espanola Valley,” said Victor Romero from the Espanola Valley Chamber of Commerce. Locals are thrilled with the publicity. “I think it’s going to open a lot of doors, you know? Hopefully, it grows there in space, and I think everyone will jump into the growing of the chile,” said chile farmer Fidel Martinez.

The española is an old chile pepper, has a slightly stronger pungent and bitter flavor and matures early to red, first grown by the Spanish settlers in the San Juan Valley, near modern-day Española, New Mexico. The Española Improved is a hybrid of the Sandia and Española, and provides Española's taste and early maturation, with a better yield, and larger peppers.

NASA Testing Method To Grow Bigger Plants In Space

In an effort to increase the ability to provide astronauts nutrients on long-duration missions as the agency plans to sustainably return to the Moon and move forward to Mars, the Veg-PONDS-02 experiment is currently underway aboard the International Space Station.

The present method of growing plants in space uses seed bags, referred to as pillows, that astronauts push water into with a syringe. Using this method makes it difficult to grow certain types of “pick and eat” crops beyond lettuce varieties. Crops like tomatoes use a large amount of water, and pillows don’t have enough holding capacity to support them.

As an alternative to the pillows, 12 passive orbital nutrient delivery system (PONDS) plant growth units are being put through their paces. The PONDS units are less expensive to produce, have more water holding capacity, provide a greater space for root growth and are a completely passive system—meaning PONDS can provide air and water to crops without extra power.

The 21-day experiment is a collaboration between NASA, Techshot, Inc., the Tupperware Brands Corporation, fluids experts at NASA’s Glenn Research Center and Mark Weislogel at Portland State University. As a U.S. National Laboratory, the space station provides commercial companies and government agencies with the ability to test the experiment in a microgravity environment.

“There comes a point where you have longer and longer duration missions, and you reach a cost benefit point where it makes sense to grow your own food,” said Howard Levine, chief scientist of NASA’s Utilization and Life Sciences Office at the agency’s Kennedy Space Center.

After Levine developed the PONDS prototype, it was passed on to Dave Reed, Techshot’s Florida operations director, and his team to re-engineer and make it capable of withstanding spaceflight. PONDS tested well on the ground, but when the system first arrived at the space station last year for testing in a microgravity environment, it pumped too much water to the lettuce seeds.

“We took a step back, evaluated different aspects of the design, and together with water fluid experts from NASA, we came up with three alternative designs, each of which had a number of components we wanted to test in space,” said Levine.

On April 19, 2019, the Veg-PONDS-02 payload arrived at the orbiting laboratory via Northrop Grumman’s 11th Commercial Resupply mission, containing 12 PONDS units in the three new design configurations. Six of the units have a clear design to allow researchers to observe the performance of water in the units during the experiment. All units contain red romaine lettuce seeds and have been placed in the two space station vegetable production systems, known as Veggie, to test growth performance.

NASA astronaut Christina Koch initiated the experiment by filling the upper reservoir on April 25. Canadian Space Agency (CSA) astronaut David Saint-Jacques filled the PONDS unit lower reservoir on May 2 and documented how water behaved in the system.

Reed and his team worked closely with material scientists and mechanical engineers with Tupperware to design and mold components that make up the PONDS-02 units.

“We needed something that was molded well, molded precisely and molded out of plastics that were compatible with edible material,” said Reed. “They brought all this huge body of knowledge to us.”

This experiment is a way to test the performance of the three alternative design methods in space to see if the water management issue initially discovered during the first PONDS experiment has been adequately addressed.

“I look at this as a normal part of the process,” said David Brady, assistant program scientist in the International Space Station Program Science Office at NASA’s Johnson Space Center. “You find what works and what doesn’t work, and you adapt and change it. The fact that Howard and his team have been able to do that is progress.”

On May 16, the final day of the experiment, the plants will be harvested. Six of the PONDS units will be returned to Earth on SpaceX’s 17th Commercial Resupply Services mission for further analysis. Reed’s team will take the successful components and combine them into one final PONDS design, which will pave the way for the agency to truly begin testing the growth capability of crop varieties beyond leafy greens.

“PONDS was an opportunity to do something that no one else has done before,” said Reed. “People have been growing plants in space since the Apollo era, but not like this.”

The Space Life and Physical Sciences Research and Applications Division (SLPSRA) of NASA’s Human Exploration and Operations Mission Directorate at NASA Headquarters in Washington is sponsoring the Veg-PONDS-02 investigation as part of its mission to conduct research that enables human spaceflight exploration.

Student Design for Space Colony Greenhouse Wins NASA Praise

A radiation-shielded, inflatable greenhouse with a hydroponic growing system designed by undergraduate students at Dartmouth College’s Thayer School of Engineering could sustain four astronauts on a 600-day mission to Mars as soon as 2030.

The students’ Deployable, Enclosed Martian Environment for Technology, Eating and Recreation (DEMETER) concept—the acronym is also the name of the Greek goddess of the harvest—won first place in the 2019 NASA Breakthrough, Innovative and Game Changing (BIG) Idea Challenge, the agency announced on April 24.

The team pitched their idea to scientists at NASA and the National Institute of Aerospace (NIA) in competition with four other finalist teams.

NASA and NIA are seeking innovative ideas for the design, installation and sustainable operation of a habitat-sized Mars greenhouse, with the primary purpose of food production, according to NASA. The agency says an efficient and safe greenhouse design could assist with Mars missions and long-term lunar missions.

The 8-meter-high by 16-m-wide DEMETER includes an automated hydroponic growing system that uses a 3-m-tall cylinder inside of a torus, with the cylinder storing the water and nutrient delivery and recycling systems. A running track for astronaut recreation circles the vertically integrated assembly of growing trays.

The team used a 1⁄6-scale proto­type to show folding methods for 1.5-m-long hydroponic growing trays, which nest against the central cylinder during transport. It also tested growing crops in a nutrient film technique hydroponic system to refine their design.

Dartmouth edged ahead when scored on the completeness of the proposed design, low system mass, optimization for food production and design simplicity, says Kevin Kempton, NASA program element manager and one of seven judges.

The team used “top-notch systems engineering throughout,” Kempton says. “That began with a systems overview that identified their system of interest relative to external systems, such as sunlight, heat, and water in the Martian environment.”

Kempton says another strength is that the components all appear relatively low risk and are based largely on a habitat design developed in a 2017 NASA feasibility study, which was the basis for the competition. “The team estimates it would take three to four missions to become a cost-effective option,” versus the cost of transporting food from Earth, Kempton says.

The team also scored high marks for innovation for the proposed concept of operations and for system deployment, which begins with robotic transport of the packaged greenhouse payload from the landing site to the deployment site. The design “seemed to have the highest level of technical maturity and it would likely require less technology development effort to get a DEMETER-base design up and running for the initial Martian outpost,” Kempton says.

NASA plans to send astronauts to the moon by 2024, with future missions in the 2030s, when a Mars greenhouse concept would potentially be viable, says Drew Hope, NASA program manager.

MIT placed second for its Biosphere Engineered Architecture for Viable Extraterrestrial Residence (BEAVER) concept. Plans include a spiral hydroponic design track in a multilevel facility featuring an enclosed waterfall for astronaut relaxation. Other finalists included designs from three state universities, California Davis, Colorado Boulder and Michigan Ann Arbor.

The finalist teams receive a shot at five NASA internships, recognition and a $6,000 stipend to travel to NASA’s Langley, Va., research center to present. All original ideas and concepts are credited to the student teams, but NASA has the option to take any portion of the ideas for use in future NASA mission planning, Hope says.

Aeroponic Farming in Microgravity
The Aeroponic Farming in Microgravity payload will evaluate an aeroponic system designed for use in a microgravity environment. The primary payload objective is observing the behavior of mist immediately after it is ejected from its source and how it moves thereafter. The secondary objective is to observe how a sample plant grows using the aeroponic system.

View fullsize

In order to examine the feasibility of using small-scale aeroponics systems in microgravity, this experiment features a chamber with an ultrasonic fogger unit. The mist is sprayed onto material containing microgreen seeds and the resulting germination and growth are imaged. Research data collected should provide a helpful model for future plant growth studies on the ISS.

Growth of Assorted Microgreens in Microgravity
The Growth of Assorted Microgreens in Microgravity payload studies the morphology and physiology of the germination of four different microgreens within modular growth chambers in microgravity.

The seeds are placed under automatic growth lighting conditions to provide day and night lighting cycles that simulate successful terrestrial lighting. While imaging and numerous environmental sensors provide an incremental evaluation of the plant growth on the International Space Station, multiple terrestrial control experiments will be conducted for comparison.  

View fullsize

The Growth of Assorted Microgreens in Microgravity experiment demonstrates modular, autonomous and retrievable crop research in space by contributing to the understanding of plant cultivation in service of food, oxygen and other habitat requirements on long-term space missions. This experiment also provides insight on plants grown under unusual conditions and can inform crop science, basic biology and horticultural applications on Earth.

NASA Technology To Grow Crops Faster

View fullsize

NASA has created a new technology to grow crops on other planets with the prospect of establishing colonies on Mars or another planet in the future. A group of scientists from the John Innes Center, the Earlham Institute, the Quadram Institute in the United Kingdom, and the University of Queensland have tested the application of this technology in terrestrial crops.

They have applied the new technology in a greenhouse at the John Innes Center in Norwick (United Kingdom). Researchers conducted rapid genetic improvements using shorter crop growth and harvest cycles, in addition to improved LED lighting. The research, which was published in the scientific journal Nature Protocols, shows that this method of cultivation can produce crops that are resistant to diseases, climate challenges, and that are more nutritious to feed a growing world population.

This technique uses improved LED illumination and day regimes of up to 22 hours to optimize photosynthesis and promote rapid crop growth. It accelerates the plants reproduction cycle: for example, it allows producers to grow six crops of wheat in a year, well above the two crops per year that are achieved with traditional improved farming methods.

By shortening breeding cycles, the method allows scientists and plant breeders to make accelerated genetic improvements, such as increasing yields, disease resistance and tolerance to climate change in a variety of crops, such as wheat, barley, rapeseed, and pea.

NASA Is Learning The Best Way To Grow Food In Space

View fullsize

Can gardens help astronauts go farther?

By Sarah Scoles June 6, 2018

View fullsize

“Our plants aren’t looking too good,” astronaut Scott Kelly tweeted from the International Space Station on December 27, 2015. He was right: The attached picture showed four baby zinnias bathed in magenta light. Three of the four leafy stalks were discolored and curling in on themselves. The station’s garden was struggling to recover from a mold problem. It’s an issue familiar to terrestrial gardeners. And while on Earth, the problem means a trip to the local nursery for replacements, in space you can’t do that.

View fullsize

Space gardens will be essential someday if astronauts are to go beyond low-earth orbit or make more than a quick trip to the moon. They can't carry all the food they need.

The Voorhes

The zinnias, brightly colored flowers in the daisy family, were part of an experiment called Veggie, whose ultimate mission is to provide crews with a long-term source of food. In prior tests, astronauts had successfully harvested lettuce. The zinnias had a longer growth ­period—60 to 80 days—and then would bloom, producing neon-hued blossoms that look like they belong in a psychedelic corsage. They were practice for something finickier and tastier than leafy greens: tomatoes. If station crews were ever going to grow something that intricate, they needed to figure out—among other things— how to vanquish mold.

Veggie is a relatively uncomplicated way for astronauts to develop their green thumbs. “It’s a very simple system,” says Gioia Massa, one of the project’s lead scientists. “It doesn’t control much at all.” Instead, the humans do.

Space gardening will be essential someday if space travelers are to go beyond low-Earth orbit or make more than a quick trip to the moon. They can’t carry on all the food they need, and the rations they do bring will lose nutrients. So astronauts will need a replenishable stash, with extra vitamins. They’ll also require ways to make more oxygen, recycle waste, and help them not miss home so much. Space gardens can, theoretically, help accomplish all of that.

Veggie and other systems aboard the space station are helping researchers figure out how radiation and lack of gravity affect plants, how much water is Goldilocks-good, and how to deal with deplorables like mold. Just as important, scientists are learning how much work astronauts have to put in, how much work they want to put in, and how plants nourish their brains as well as their bodies.

For all its potential importance, Veggie is pretty compact. It weighs 41 pounds, just a hair less than the station’s 44-pound coffeemaker. The top—an off-white rectangular box that houses the grow lights—resembles an old VCR. From this, a ­curtain of clear plastic hangs to encase the ­1.7-square-foot planting surface. Astronauts preset how long the lights stay on each day; how brightly they emit red light to optimize photosynthesis, and blue light to control the plants’ form and function. They can also ­activate a built-in fan to adjust the humidity.

The most important part of Veggie, though, is the fragile bounty it is meant to cultivate. That begins as seeds encased in little ­Teflon- coated Kevlar pouches. The scientists call them plant pillows. “You can think of it like a grow bag,” Massa says of these packets stuffed with seeds, water wicks, fertilizer, and soil.

People have anticipated this scenario for more than a century. In 1880, science-fiction author Percy Greg wrote Across the Zodiac, a novel about an astronaut who traveled to Mars with plants to recycle waste. Fifteen years later, Konstantin Tsiolkovsky, a Russian rocket scientist, wrote Dreams of Earth and Sky, which laid out how spacefarers and flora could live together inside a closed system.

In the 1950s, green things burst from book covers and into the lab. NASA and the U.S. Air Force started growing algae to see if it could help with life support (turns out, it tasted bad, was full of indigestible cell walls, and had too much protein). Then, Soviet scientists experimented with nearly self-sufficient ecosystems in which humans survived on oxygen, water, and nutrition produced mostly within an enclosed habitat.

In the longest run, a 180-day trial inside a facility called BIOS-3, an earthbound crew got 80 percent of its food from its own wheat and vegetables. Finally, in 1982, plants in space became a reality when Soviet cosmonauts grew Arabidopsis thaliana, a flowering species related to cabbage and mustard, to maturity aboard their Salyut 7 space station. The yield was too small to be a source of food.

Liquid refreshment

Astronauts dispense precise amounts of water to the plants inside Veggie.

NASA

Around this time, in the mid-’80s, ­Veggie’s Massa was in middle school, and her ­seventh- grade teacher returned from an astro­agriculture workshop at Kennedy Space ­Center with reams of information on the topic. Inspired, a teenage Massa kept taking ag classes as she moved on to high school, and later teamed up with her middle-school ­mentor for a hydroponics project.

While Massa continued her studies and self-guided experimentation, NASA began building orbital plant-growing apparatus, most notably the Biomass Production System. Designed to be used for experiments on the space station, it was a rectangle with sides each about the length of an arm. Four cube-shaped growth chambers rested like safes inside. Designed by scientists at a Wisconsin-based company, ­Orbitec, the Biomass Production System joined the space station in 2001. There, Brassica rapa field mustard soon sprouted tall, illuminated by plain white fluorescent light.

When researchers compared the harvest to a control plant on the ground, though, they found that the space mustard had more bacteria and fungus. “The significance of the difference is uncertain,” states NASA’s official conclusion. By which the agency meant it didn’t know why the microbes proliferated, not that their presence wasn’t important. In fact, as Veggie’s mold would show, it was critically important.

NASA retired the Biomass Production System in 2002, but Russian cosmonauts picked up where the U.S. left off. Over the decade, they successfully grew dwarf wheat, leafy mizuna, and dwarf peas. Bonus: In four successive generations of orbiting dwarf peas, the vegetables didn’t show signs of genetic messiness.

Could underwater farming feed the world?

Ocean-bound entrepreneur envisions ecological restoration and economic revival.

American entrepreneur Bren Smith says he can feed the world with an area roughly the size of Washington State. And he wouldn’t need one inch of farmland to do it.

Meanwhile Orbitec, in consultation with NASA, cultivated another plant-growing ­instrument. So when NASA awarded a grant in 2012 for a new space garden, the company had something to show for itself: Veggie, which, unlike its predecessor, was meant to produce food on an edible scale. Massa, by then a postdoc, tested different types of ­media and crops for the plant pillows. It was the kind of tinkering she’d been preparing for since she was 12. The United States’ first real space garden launched in 2014, not long after Massa advanced from her postdoc to become a Veggie project scientist at the space agency.

All went pretty well for Veggie until the flower flap. Most of its initial ­edible plants—a lettuce variety called Outredgeous—sprouted as they should have in 2014, and the astronauts shot them back down to Earth for testing. Massa says they’re still working on all the analyses. “But in general, the plants are pretty similar to our ground samples.” When they’re finished, they’ll know about chemical contents like antioxidants, anthocyanin (pigments), and phenolics, which protect plants against stress. Short term, the priority was mealtime: Could we have consumed the harvest? The crew, Massa, and NASA all wanted to know. Yes, it turned out, the produce was microbially safe to eat.

Still, when the astronauts planted a second set of seeds, in summer 2015, Massa ran into a new challenge: With harvest approaching, NASA had no protocol to approve the crew chowing down on the leaves of their labor. “We said, ‘We have only 28 days, and then they’re going to have to eat it,’” Massa recalls. With the clock ticking, management found a way to ­officially add the lettuce to the astronauts’ diet.

On August 9, Kelly snapped a picture, standing in front of the unfurling greens. His brow was furrowed, faux-serious. “­Tomorrow we’ll eat the anticipated veggie harvest on @space_station!” he tweeted. “But first, lettuce take a #selfie.” Soon he crunched the harvest live on NASA TV. It might seem like no big deal, but a single leaf can make a big difference to someone who’s been eating rehydrated fare for months. During a later harvest, astronaut Peggy Whitson would use them to wrap a reconstituted lobster salad. “Even with a really good diet with hundreds of items, there’s dietary fatigue,” Massa says. “People get bored. Adding a new flavor or texture—like something crisp and juicy—could spice up your regular meal.”

That’s not the only brain boost. Sure, astronauts can gaze down at Earth and see its most beautiful spots—literally all of them—every 90 minutes. But those places are always out of reach, reminders of how far away sea level is. Having something nearby that photosynthesizes might cheer the crew. “It’s the psychological aspect of something green and growing when you’re far away from home,” Massa says.

In the next growing cycle, the astronauts fostered the ill-fated zinnias. About two weeks in, Kjell Lindgren saw the first warning signs. Water leaked from the wicks that hold the seeds. Then moisture began seeping from the infant leaves, which started to curl in on themselves. Veggie staff on the ground, in charge of the operation, decided it was time to turn the airflow fan from low to high. But an impromptu spacewalk to fix a broken robotic arm delayed the change because, in space, nothing is as simple as flicking a switch on your way out of the spaceship. While reprogramming Veggie’s settings takes only about 15 minutes, NASA prefers astronauts move anything lower priority out of the way when they have a high-priority task.

And then the leaves started to die.

That’s bad enough on its own. But, worse, dying vegetation can be a breeding ground for mold, which had somehow come to space with the astronauts and cargo. Soon, menacing white fuzz began choking the plants.

By this time, Lindgren had returned to Earth, and Kelly had taken over the garden. On December 22, with instructions from ground control, Kelly snipped away the moldy parts like bad spots from a piece of cheese, and swabbed the remaining zinnias and equipment with cleaning wipes. He left the fans on high to help dehydrate the setup.

It was a good try but not without a cost: It made the plants thirsty. Kelly relayed that to ground control and asked to water them. Sergeants who were set on sticking to the drill told Kelly it wasn’t time yet. Not till December 27. “You know, I think if we’re going to Mars, and we were growing stuff, we would be responsible for deciding when the stuff needed water,” Kelly told them, according to NASA’s write-up of the event.

Farm to table

Eventually, they gave autonomy to the person who was actually next to the plants, along with one page of instructions called “The ­Zinnia Care Guide for the On-Orbit Gardener.”

Under the On-Orbit Gardener’s thumb, half of the zinnias revived, unfurling and growing green. NASA spun the whole thing as a positive: They now knew that crops could survive floods, drought, and disease, and that excising the problem plants and cleaning the remainder could keep the fungus from taking over.

Kelly loved the now-flourishing flowers and carried their container all over the space station for photo shoots, like those people who snap shots of themselves in Hard Rock T-shirts all over the world. “He asked if he could harvest them on Valentine’s Day,” Massa says. He’d been in space, away from everyone ­except his smelly crew mates for more than 300 days. NASA let him make the bouquet.

It was one of Massa’s favorite moments. “We had been a part of something that gave him pleasure,” she says.

In upcoming Veggie experiments, scientists will learn more about that part of gardening—the mental part. “We’ve heard a lot anecdotally,” Massa says, “but we’ve never been able to collect data.” They’ll also investigate how much farming crewmembers actually want to do, how much is fun versus how much is a chore, how their sense of taste changes in orbit, and which plants can survive human error (no offense, astronauts).

Veggie’s experiments will continue in tandem with those of a brand-new Type-A companion, the Advanced Plant Habitat, an 18-inch-square self-sufficient laboratory with more than 180 sensors and automated watering. Scientists can establish their variables and thus nail down the specific conditions that cultivate plants—and how those plants can ­cultivate humans. A temperature-­control system keeps the air within 0.5°C of the thermo­stat setting. Sensors relay data about air temperature, light, moisture, and oxy­gen levels back to base. While the Advanced Plant Habitat will quantify the circumstances for successful gardening, Veggie will help qualify how—and why—humans can facilitate their own food supply. In other words, through the habitat’s tight controls, researchers can learn how to grow which plants best. Then, using those parameters, they can set up a system like Veggie that astronauts get to interact with.

Astronauts assembled the habitat over six hours in October 2017, after it rumbled into space in two shipments. The automated contraption looks like a microwave that could survive… being shot into space. Wires stream from here to there and there to here on a control panel. Red indicator lights blink next to toggle switches. And inside the plant chamber, LEDs beam from the ceiling, illuminating the plants below with concert-stage color combinations. It has red, green, and blue lights like Veggie—plus white, near-, and far-infrared ones.

Plants might also be a brain boost. "It's the psychological aspect of having something green and growing when you're far away fom home," says Massa.

The Voorhes

Robert Richter, director of environmental systems at Sierra Nevada Corporation, which acquired Orbi­tec in 2014, monitored its progress from the earthbound Space Station Processing Facility. He’d helped design and build the new lab, as well as Veggie and Biomass. When he started in the field, almost 20 years ago, he was a bit ­naive. “I thought, How hard is it to grow plants?”

He’s partly joking, of course—and he knows, now, that when you’re trying to keep the humidity level within 3 percent of a given ­number, when you must make and measure light and moisture, and when you maintain the temperature to a fraction of a degree, there’s a long row to hoe between growing some basil in a cup and farming lettuce in space.

The team powered up the unit in November 2017. And by February this year, test crops of Arabidopsis thaliana and dwarf wheat sprouted. Soon, they’ll begin experiments like investigating plants’ DNA and physiological changes. A lot of the previous plant research has been focused on whether things would grow at all, says Robert Morrow, Sierra Nevada Corporation’s principal scientist. Will they reproduce from generation to generation? And are they as productive in space as on the ground?

Yes, he says. Scientists are beyond those basics now. They need to dig into the dirtier details and more-complicated ecosystems. ­Astronauts, for instance, exhale carbon ­dioxide that plants can inhale. The plants then exhale oxygen, which humans can inhale. ­Human waste can become plant fertilizer and hydration. Nothing wasted, everything gained.

Ultimately, Morrow believes, a garden on a deep-space mission will be more like Veggie than like the Advanced Space Habitat. “It’s really not practical to put all the stuff you have in APH in a system like that,” he says. With so many sensors and tubes, lots can go mechanically wrong, and it’s easier to repair a Veggie than an APH. For now, scientists need APH to home in on optimal guidelines for plant growth and understand how leaving the planet changes them so they can instruct future astronauts how to better manage Veggie-esque systems.

Looking toward the future, Massa is interested in observing astronaut interactions with the instruments. “Do you always want to pick your ripe tomatoes, but maybe you don’t want to have to water them every other day?” she wonders. She’ll have a chance to find out ­because Veggie will grow its first dwarf tomatoes, a variety called Red Robin, early next year.

Other nations continue to experiment too. China, for instance, intends to send silkworms and potato seeds to the moon this year aboard its Chang’e-4 spacecraft. When the silkworms hatch, they’ll create carbon dioxide, which the potato plants will suck up and turn into oxygen, which the silkworms will then take up.

All this research doesn’t just help ­people above the atmosphere. Creating ­self-­contained growth systems might help farmers on Earth grow crops year-round or foster plants with extra protein and high yield. Someday, the work will lead to gardening systems ­substantial—and stable—enough to support space journeyers. Then, those travelers can wrap anything they want in lettuce and crunch their way through the cosmos.
