Former salmon farmer Dr. Carl Mazur aims to design an aquaponics system that could one day be used on Mars. In the meantime, he aims to use it to produce high-value fish and flowers on Earth.
Can you tell us a bit about your aquaculture experience?
My aquaculture experience is primarily with saltwater salmon production on the east and west coast of Vancouver Island, in Canada. I gained hands-on experience immediately after graduation from McGill University with a degree in marine biology. This was in the mid-1980s and the issues we had with fish loss due to bacterial kidney disease at the time lead me to pursue a master’s and then a Ph.D. at UBC, focused on the effects of rearing and environmental fish stressors on their immune systems and disease susceptibility.
The Terra-Mars project may be ambitious in the long run but it aims to start with more modest goals
Why did you decide to return to the sector and what inspired you to look into aquaponics specifically?
I returned to the sector after owning and operating a national licensing, sales, and distribution in Canada focused on providing human tissue regeneration products to dental and medical specialists across Canada for 15 years. I returned as I had always intended to do so and had gone to the biotech sector to support my family and to learn business lessons that I could then bring back to the aquaculture/aquaponics sector. My first love is “all things marine” and it’s great to be back in a sector where I feel at home.
The reason for migrating a short step from aquaculture to aquaponics is that I feel aquaponics is more holistic in that a well-conceived aquaponic system can essentially be near-closed and self-sustaining. Aquaponics systems today do need external input in the form of fish feed which then provides carbon, nitrogen, and phosphorous (and other trace elements) for plant growth. The next step in closing the loop will be to produce fish feed from the carbon, nitrogen, and phosphorous delivered from the system in the form of human food, fish offal, and the inedible stem and root plant products.
From aquaponics to aquaponics on Mars, that sounds like quite a leap. What's the logic?
The simple premise behind developing an aquaponic system for use on Mars [as part of the Terra-Mars project] is that a system advanced enough to be on Mars will be able to grow food anywhere on Earth, with modifications. The ultimate goal is to have a system that can provide food security for any environment on Earth and thereby end the suffering that still occurs in some developing countries. Having the ambitious goal of developing a food production system for Mars should provide ample PR exposure which can then be leveraged to promote the project and help to carry it forward.
It must be noted that the initial systems will be produced on a small scale and will be developed to produce high-value fish for the ornamental aquarium fish sector and high-value plants for the fine dining and floral industries. The technologies developed for these high-valued products will later be used for larger projects which will produce higher volume, lower value products for middle class consumers. Eventually, we will transition to industrial-scale operations for low price, mass consumption products. This model is borrowed from the automotive industry, as demonstrated and proven by Tesla motors.
What species of fish are you thinking of growing in your system on Mars?
The three species of fish we’ve shortlisted to date for Mars are tilapia, barramundi and Arctic char. We’ll need to test many species under the simulated Earth environment that we’ll attempt to create in our simulated Martian environment.
Are you able to apply the skills that you gained in the conventional aquaculture sector for the project?
Yes, many of the skills gained in the conventional aquaculture sector (especially related to fish health and nutrition) can certainly be used with this project.
Who are your key collaborators and what do they bring to the project?
The key collaborator for this project is Dr. James Rakocy, known worldwide as the “father of aquaponics”. Dr. Rakocy has had a distinguished 30-year career at the University of the Virgin Islands and his UVI aquaponic system is known worldwide as the best researched and established system for growing tilapia and a variety of greens including lettuces and herbs. Dr. Rakocy is the author of the seminal book Aquaponic Q&A. His educational aquaponic systems are used in over 1,100 high schools across America for foundational teaching in the STEM areas of biology, chemistry, math, and food systems.
Other key collaborators are Garth Wardell, CEO / owner of Allsite IT, a digital intelligence firm currently dedicated to the advancement of intense data solutions for the hospitality and healthcare sectors. Garth is very keen about this project and has been a trusted advisor since 2018. Several other advisors in the areas of law, engineering, computer science, multimedia technologies, education, urban farming, and accounting are also on standby and eager to begin work on this project.
The other noteworthy collaborator is Dr. Christopher McKay, an astrobiologist at the NASA Ames research centre in California, who has offered assistance at the academic level and must sit as an unpaid advisor, as is mandated for all full-time NASA employees.
How have your plans been received to date?
The plans have been very well received to date, most notably by Elon Musk who was informed of the intentions several years ago and stated that “this will be very important down the road”. Mr Musk was presented the concept for informational uses only and was not approached for funding or resources, as he had intense funding and resource requirements at Tesla and SpaceX at the time.
How much money are you hoping to raise for the project and what will you use this for?
The initial round of financing for this project will be for $2.6 million and will be used to:
Develop a first aquaponic system prototype.
Secure an IP patent portfolio of aquaponic patents.
Build a physical model of the Space Exploration Theme park
Develop a mixed reality (VR&AR) tour of the park
Perform an extensive feasibility study for the project.
What are the key milestones for your project?
Obtain the initial round of seed funding.
Become cash-flow positive with the acquisition of existing ancillary businesses in the fish, vegetable and floral, growth, packaging, distribution, retail, media and entertainment sectors.
Building global brand recognition for Terra-mars products and entertainment facilities.
Acquisition of real estate (primarily distressed suburban shopping malls) where the aquaponic facilities will be installed to grow the fish and plants for local distribution to populations in North America and Europe.
Series A financing round to raise $100 million in 2023 or 2024 at the latest.
What is the end goal for your project and do you think that this is feasible to achieve in your own lifetime?
The end goal for phase one of the project is to have four Space / Mars exploration theme parks – one in North America, one in Europe, one in MENA, and one in China. These will have the dual purpose of entertainment and providing research facilities for Mars colonization technologies, featuring the aquaponic food production system. Other technologies for Mars colonization will be in the fields of transportation, communications, housing, healthcare, and recreation.
If you don’t make it to Mars, where will you target using your aquaponics systems on the Earth?
If we don’t make it to Mars, the aquaponic system will first be used to produce high value fish and plants for Western markets and eventually be developed in for larger commercial operations to be used anywhere on earth.
What are the major challenges that you still need to overcome?
The major challenges which we need to overcome are to raise the initial round of financing and to become cashflow positive in the shortest time possible.

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

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.
