In space exploration, LIDAR (LIght Detection And Ranging) is an important sensor technology for terrain
observation, navigation assistance for planetary landings, and orbital rendezvous. Further development
of LIDAR sensors is also expected in future space development through interactions with the growing
commercial space and ground industries, which have a large market size. In this paper, the thermal
vacuum environment and space radiation environment are described as environmental conditions unique
to space that must be considered for use of LIDAR in space. In addition, relatively new examples of
spacecraft applications are introduced, including Flash LIDAR on the HTV-X, a new resupply ship under
development for the International Space Station, and LRF (Laser Range Finder) on SLIM, which made
the first successful pinpoint landing on the Moon.
