NASA’s quest to grow food on Mars: pioneering plant research in space


Amid the rust-red tones of the Martian landscape and the eerie silence of an alien world, a team of astronauts imagine a future where human life thrives. NASA Expedition 71 crew members aboard the International Space Station (ISS) are conducting a groundbreaking study titled ‘Plant Responses to the Stresses of Microgravity and High Ultraviolet Radiation in Space’ (Plant UV-B) to discover the secrets of plant growth in space.

The Martian table: a search for sustenance

As the duration of trips to Mars increases, the need to grow food becomes paramount. Carrying enough supplies for the trip is an unfeasible option, so it is essential that astronauts cultivate their own sustenance upon arrival. Scientists like Mike Dixon at the University of Guelph are working tirelessly to develop reliable plant life support systems that can enable this vision.

From Earth to Mars: the UV-B plant experiment

The Plant UV-B study, currently underway on the ISS, investigates how microgravity stress, ultraviolet radiation and their combined effects influence plant growth at the molecular, cellular and whole-organism levels. This research aims to improve our understanding of plant development in space, paving the way for advances in growing technologies for future missions to the Moon and Mars.

Creating a bubble of life: the Mars greenhouse

Scientists have devised a reliable life support system for growing food on Mars, encapsulating plants inside a pressurized container to protect them from the freezing, near-vacuum conditions on the Martian surface. The day-night cycle on Mars closely mirrors that of Earth, offering an optimal environment for terrestrial plants to flourish. However, maintaining the necessary temperature and life support systems requires a constant supply of energy.

In terms of caloric yield per land area, potatoes emerge as the ideal crop for Mars. This remarkable advance brings us one step closer to realizing the dream of sustaining human life on the Red Planet.

As research progresses and the Martian table takes shape, the implications go far beyond the immediate needs of astronauts. The knowledge gained from these studies could revolutionize agriculture on Earth, particularly in hostile and inhospitable environments. The Mars greenhouse project holds the promise of nurturing life in the most unlikely places, fostering resilience and ingenuity in the face of adversity.

As the Expedition 71 crew continues their work aboard the ISS, they are not only laying the foundation for human life on Mars but also redefining the limits of what is possible here on Earth. Their efforts serve as a testament to humanity’s unbreakable spirit, determination and capacity for innovation.

In the vast expanse of the cosmos, the quest to grow food on Mars represents a ray of hope, lighting the way for future generations to explore, learn, and ultimately call the stars their home.
