In this 2021 photo provided by the University of Florida, Institute of Food and Agricultural Sciences, a researcher harvests a thale cress plant growing in lunar soil, at a laboratory in Gainesville, Fla. For the first time, scientists have used lunar soil collected by long-ago moonwalkers to grow plants, with results promising enough that NASA and others already are envisioning hothouses on the moon for the next generation of lunar explorers.
