Scientists have, for the first time, grown plants in soil from the Moon. They used soil collected during the Apollo 11, 12 and 17 missions. In their experiment, the researchers wanted to know if plants would grow in lunar soil and, if so, how the plants would respond to the unfamiliar environment, even down to the level of gene expression.
Scientists have grown plants in soil from the Moon, a first in human history and a milestone in lunar and space exploration.
In a new paper published in the journal Communications Biology, University of Florida researchers showed that plants can successfully sprout and grow in lunar soil. Their study also investigated how plants respond biologically to the Moon’s soil, also known as lunar regolith, which is radically different from soil found on Earth.
This work is a first step toward one day growing plants for food and oxygen on the Moon or during space missions. More immediately, this research comes as the Artemis Program plans to return humans to the Moon.
“Artemis will require a better understanding of how to grow plants in space,” said Rob Ferl, one of the study’s authors and a distinguished professor of horticultural sciences in the UF Institute of Food and Agricultural Sciences (UF/IFAS).
Even in the early days of lunar exploration, plants played an important role, said Anna-Lisa Paul, also one of the study’s authors and a research professor of horticultural sciences in UF/IFAS.
“Plants helped establish that the soil samples brought back from the moon did not harbor pathogens or other unknown components that would harm terrestrial life, but those plants were only dusted with the lunar regolith and were never actually grown in it,” Paul said.
Paul and Ferl are internationally recognized experts in the study of plants in space. Through the UF Space Plants Lab, they have sent experiments on space shuttles, to the International Space Station and on suborbital flights.
“For future, longer space missions, we may use the Moon as a hub or launching pad. It makes sense that we would want to use the soil that’s already there to grow plants,” Ferl said. “So, what happens when you grow plants in lunar soil, something that is totally outside of a plant’s evolutionary experience? What would plants do in a lunar greenhouse? Could we have lunar farmers?” Read more from Science Daily.
