The Mini-RF project launched two radar instruments to the Moon. The first instrument launched on the Indian Space Research Organization’s Chandrayaan-1 spacecraft. The second instrument currently is flying on NASA’s Lunar Reconnaissance Orbiter (LRO).
The primary goal of the Mini-RF is to search for subsurface water ice deposits. In addition to taking high-resolution imagery of permanently-shadowed regions.
