Scientists grow 1st plants in moon soil

SUGGESTED NEWS


More than 50 years after astronauts brought the last moon-rock samples to Earth, scientists have successfully grown plants in lunar soil from three Apollo missions for the first time. 

All the moon-soil plants grew slowly and relatively poorly, but those grown in samples that had been more exposed on the lunar surface tended to do the worst, and genetic analysis showed changes indicative of stress. The poor growth might be cause for concern: As NASA prepares to send astronauts back to the moon through its Artemis program — and eventually even to Mars — being able to grow food in extraterrestrial soil during long missions will become increasingly important.
