What plants can grow on the moon?

Lunaria One international consortium including Ben-Gurion University to send plants to moon on Beresheet2 lunar lander.

Can plants grow in a barren landscape such as the surface of the moon? If so, what types of plants? Could enough plants grow to support a future peopled moon installation? These are the ambitious questions the Lunaria One consortium has set out to answer.

Lunaria One's Aleph was selected recently for a spot on SpaceIL's next lunar lander Beresheet2 scheduled to land on the moon in 2025. Aleph will consist of a tray of seeds and dehydrated plants, a way to rehydrate and water them, heaters, and cameras to monitor the plants.

Prof. Simon Barak, of the Jacob Blaustein Institutes for Desert Research (BIDR) at Ben-Gurion University of the Negev, is coordinating all the plant biologists and imaging specialists. They include three from Australia, one from South Africa and two of his colleagues from BIDR at Ben-Gurion University: Prof. Aaron Fait and Dr. Tarin Paz-Kagan.

Shimon Sarid, SpaceIL CEO: "The chosen experiment has enormous value both for our life here on Earth and for humanity's progress in space exploration. Examining plant growth under extreme conditions will help us to act correctly as far as food security is concerned, plant growth will help humanity in long-term tasks. We are happy to cooperate with Lunaria One and are very excited."

"The motivation for this mission comes from humanity’s passion to explore and see life thrive in barren landscapes. We see the Aleph payload as the first step towards our eventual goal of providing plants for food, medicine, oxygen production, CO2-scrubbing and general well-being for future astronauts inhabiting the moon and beyond," explains Prof. Barak.

“The central value guiding this project is that space exploration is for everyone; we don’t want a future where only autonomous and remote-controlled machines inhabit realms beyond earth, but where humans can live and thrive. The key to this is to get humans involved and to give them a say in how we get there. The ALEPH project aims to open up the science and engineering behind growing life on the Moon so that anyone can be involved.” – Lauren Fell, Director, Lunaria One.

Growing plants on the moon mean overcoming several challenges such as massive temperature swings on the way to the moon, a water supply for the plants, and high temperatures when growing the plants. The plant types will need to be those that can germinate and grow to an appropriate size for imaging within 72 hours of deployment.

In the meantime, they expect their plant selections to be relevant for vertical farming and resource-challenged landscapes here on Earth.

The project also has a strong citizen science component. Parallel science experiments will be carried out by amateurs (for example, high school students) and professionals to compare growth to that on the Moon.

Additional universities participating in Lunaria One include: QUT, RMIT, and ANU in Australia and The University of Cape Town in South Africa.

Lunaria One comprises an interdisciplinary team who have coalesced around the goal of putting plants on the Moon and involving citizens and schoolchildren in the process. The team includes scientists from Australia, Israel, South Africa and the USA. Dr Alan Finkel is the overall patron of the project. Deployment of the ALEPH-1 payload is the first step in a series of planned projects to work toward growing plants for future human inhabitants of the Moon.
