NASA Enhances Lunar Mission Accuracy with Laser Retroreflective Arrays

The simple yet effective Laser Retroreflective Arrays (LRAs) are set to improve the precision of lunar lander locations, marking a significant advancement in space navigation.

• NASA is utilizing Laser Retroreflective Arrays (LRAs) to pinpoint the locations of lunar landers with greater accuracy, a key component of the Commercial Lunar Payload Service (CLPS) initiative.
• LRAs, small and lightweight, are designed to reflect laser light from a wide range of angles, facilitating precise location determination.
• The technology aids in the docking of spacecraft, including those used for the International Space Station, by illuminating upon laser contact and allowing for precision docking even in darkness.
• LRAs can withstand the harsh lunar environment for decades, enhancing long-term navigation and scientific missions on the Moon.
• The deployment of LRAs on lunar missions supports NASA's Artemis program, aiming to land the first woman and first person of color on the Moon and establish a long-term presence.
