Study finds asteroid impact 3.8 billion years ago created massive moon canyons, aiding NASA's Artemis program.

A recent study reveals that an asteroid impact about 3.8 billion years ago created two massive canyons on the moon's far side, comparable to Arizona's Grand Canyon. The impact, estimated to be 15 miles wide, ejected debris at high speeds, forming the canyons within 10 minutes. NASA finds this information valuable for its Artemis program, aiming to land astronauts at the moon's south pole, where older rocks remain intact, offering insights into the moon's and Earth's origins. The study also suggests that permanent shadow areas at the south pole may contain ice useful for future lunar missions.
