In the future, rocketing in making precision landings on the moon's craggy, rocky and crater-pocked face won't be as hard.
At least that's the goal of NASA's Lunar Retroreflector Array (LRA) program, an initiative that is interfacing with U.S. and foreign lunar lander initiatives. LRA consists of a dome-shaped device, topped by small glass prism retroreflectors. That contrivance is then mounted to a moon lander and delivered to the lunar surface.
