We compare the Centaur impact features, positively identified in the first two, and with a consistent feature in the third, which are interpreted as a 20 m diameter crater surrounded by a 160 m diameter ejecta region. #LUNAR RECONNAISSANCE ORBITER REGISTRATION#This paper describes the registration of imagery of the LCROSS impact region from the mid- and near-infrared cameras onboard the SSC, as well as from the Goldstone radar. The Sheperding Spacecraft (SSC) separated ∼9 hours before impact and performed a small braking maneuver in order to observe the Centaur impact plume, looking for evidence of water and other volatiles, before impacting itself. These detectors were designed to absorb radiation in the same way as human bone and muscle tissue.The Lunar CRater Observations and Sensing Satellite (LCROSS) mission impacted a spent Centaur rocket stage into a permanently shadowed region near the lunar south pole. To that end, the Cosmic Ray Telescope for the Effects of Radiation carried two special silicon and plastic detectors aboard the LRO, one aimed toward the lunar surface and the other spaceward. National Aeronautics and Space Administration had given highest priority to characterization of the radiation environment in lunar orbit since this would have been a major health consideration for space crews on future missions of the proposed Constellation program. Its mission is expected to last into the 2020s. In 2015 its orbit was lowered to a height of 20 km (12 miles) above the Moon’s south pole. After transferring from Earth orbit to lunar orbit, the LRO was placed in an elliptical, polar commissioning orbit for approximately two months before using onboard thrusters to lower its orbit to a height of 50 km (30 miles). #LUNAR RECONNAISSANCE ORBITER SERIES#After a series of postponements, the LRO was successfully launched on June 18, 2009, from Cape Canaveral, Florida, on an Atlas rocket that also launched the Lunar Crater Observation and Sensing Satellite (LCROSS), which was designed to seek water at the lunar south pole. spacecraft that mapped the surface of the Moon in order to help select ideal sites for uncrewed and eventually crewed lunar landers.
