A first: Scientists grow plants in soil from the Moon:

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.

[...] "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?"

[...] The complication: The scientists only had 12 grams -- just a few teaspoons -- of lunar soil with which to do this experiment. On loan from NASA, this soil was collected during the Apollo 11, 12 and 17 missions to the Moon. Paul and Ferl applied three times over the course of 11 years for a chance to work with the lunar regolith.

[...] Before the experiment, the researchers weren't sure if the seeds planted in the lunar soils would sprout. But nearly all of them did.
