Probing our nearest Celestial Neighbor

APL's lunar experts study everything from how craters form to how volatile molecules such as hydrogen are distributed around the Moon. They study the chemical composition, weathering, geology and volcanic history of the Moon and help to lead several instruments on NASA’s Lunar Reconnaissance Orbiter (LRO) – including cameras that have imaged the Moon in unprecedented detail, and the Mini-RF instruments that use radar to provide critical information about volatile molecules on the lunar surface. APL also operates the Lunar Surface Innovation Consortium (LSIC), which connects experts from academia, industry and government to shape the technologies and systems needed to explore the Moon in new ways.

Instruments

Scientists and engineers at APL have designed, built and operated more than 300 novel space instruments and methods to conduct cutting-edge research and make groundbreaking discoveries.
