Astronaut Mark Watney’s journey to grow potatoes on Mars in the film Martian may be fiction, but real-world astrobotanists like Jessica Atkin are making strides in the field. As NASA gears up to establish a sustainable lunar base through the Artemis II mission, the need for skilled individuals who can cultivate crops off Earth is becoming paramount.
Establishing a self-sufficient moon base poses challenges, including the requirement for colonists to harvest water from lunar ice and contend with the inhospitable lunar regolith. Atkin’s groundbreaking research, undertaken at Texas A&M University, demonstrates that chickpeas can sprout when lunar regolith is treated with a blend of organic materials and particular fungi. Her work recently earned her a significant NASA grant to advance research on lunar agriculture.
Atkin discussed her aspirations for a lunar greenhouse, the importance of her work, and what future astronauts can expect to eat on the moon.
Robin George Andrews: What motivated your interest in astrobotany?
Jessica Atkin: My passion for plants began in my childhood, specifically in my grandmother’s strawberry fields. Growing up on a ranch, I spent evenings pondering the possibilities of cultivating plants in space. My belief is that microbes could help us in the process of colonizing not just Earth but the Moon as well.
How did your military service shape your academic career?
My time in the military was a stepping stone to obtaining my college education without financial dependence on my family. I served as a police officer and trained the Iraqi police, experiences that taught me resilience and adaptability—qualities I now bring to my research.
Why grow crops in lunar regolith instead of transporting soil from Earth?
Transporting 1 pound to the Moon can cost around $100,000, making it impractical for sustaining long-term food growth. Instead, we’ll focus on leveraging hydroponics and other innovative methods, much like the systems used on the International Space Station (ISS).
What challenges does lunar regolith present for agriculture?
The structure of lunar regolith is detrimental to plant growth; its sharp, small particles can harm both plants and astronauts alike. Moreover, the chemical composition, while containing necessary nutrients, poses risks due to potentially toxic elements that can inhibit plant health.

What progress has been made in lunar agriculture?
Research teams, such as those from the University of Florida, have shown that plants like thale watercress can grow in actual lunar regolith samples collected during the Apollo missions. My initial research overlooked the vital role of microbes in plant growth, and I felt compelled to explore their significance further.
Your work emphasizes the importance of fungi in lunar agriculture.
Understanding that fungi can aid plants in establishing themselves on land here on Earth, I wanted to investigate if a similar symbiotic relationship could help plants thrive in lunar regolith.
Why did you choose chickpeas as a candidate for lunar cultivation?
Chickpeas are often overlooked as crops, yet they are rich in protein and serve as a vital food source. Unlike typical crops like lettuce and tomatoes, chickpeas are resilient and capable of thriving in harsh conditions, making them ideal for lunar agriculture.
Before your NASA grant, you pioneered research in your home.
My living room transformed into a botanical lab, as I knew that exploring these experiments was crucial when few others were doing so.
Were you able to utilize real lunar regolith in your studies?
Full samples of lunar regolith are scarce and heavily guarded at NASA’s Johnson Space Center; thus, I utilized lunar simulants created from terrestrial volcanic rock to replicate the lunar environment effectively.

What is the current state of your lunar agriculture research?
Atkin’s ongoing studies focus on combining fungi with compost to ascertain the optimal amount of organic material that will successfully nourish plants and microbes in lunar regolith. Remarkably, chickpeas have shown rapid germination, hinting at a potential agricultural revolution on the Moon.
What obstacles do you foresee for future lunar vegetable gardens?
The elevated radiation levels on the Moon and its gravitational differences can significantly alter plant growth, making effective lighting and optimal watering strategies crucial. This will necessitate specially designed, isolated greenhouses to protect both astronauts and plants from lunar dust.
What is your vision for the future of astronaut diets?
I believe the diet of astronauts will increasingly rely on shelf-stable and packaged foods, with legumes like chickpeas providing essential nutrients. The future could even see the introduction of lunar-grown foods like space hummus!
What culinary delights do you envision in a lunar greenhouse?
I have a soft spot for fruits, particularly strawberries, which are currently undergoing tests for growth in space. NASA is exploring various crops, including strawberries in space.
How do you feel about being dubbed the Botanist of the Moon?
While it’s a niche title, I embrace it as an opportunity in a burgeoning field, especially as NASA’s Artemis program progresses. There will be high demand for specialized roles in space agriculture.
If given the opportunity, would you establish a lunar greenhouse?
Absolutely; it’s the realization of a lifelong dream! Being part of lunar exploration and agricultural innovation is something I would cherish deeply.
Reflecting on your early inspirations, what would your grandmother think of your journey?
Even though she’s no longer with us, I know she’d be immensely proud of my achievements. Her support always motivated me, and I hope to honor her legacy through my work in astrobotany.
