NASA is using a simple but surprisingly effective technology called Laser Retroreflective Arrays (LRAs) to determine the locations of lunar landers more accurately. They will be attached to landers sent to the Moon as part of NASA’s Commercial Lunar Payload Service (CLPS) initiative. LRAs are inexpensive, small, and lightweight.
