Lasers in moon craters could create a lunar GPS system

The moon’s cratered surface. Could these shadows help with making lunar GPS? (Image credit: NASA) Placing ultrastable lasers inside some of the coldest, darkest lunar craters could help scientists establish a GPS-like navigation system on the moon, allowing future Artemis astronauts and spacecraft to navigate the lunar surface more easily. Researchers at the National InstituteContinue Reading
