LCROSS Web Site

The Lunar CRater Observation and Sensing Satellite (LCROSS), managed by NASA's Ames Research Center in California, launched with LRO on June 18, 2009. LCROSS will search for water ice in a permanently shadowed crater near one of the moon's poles. Visit the Web site below for more information about LCROSS and the crater impact.

Five Things to Know about LRO

LRO is leading NASA’s way back to the moon.
The primary objective of LRO is to conduct investigations that prepare for future lunar exploration. Specifically LRO will scout for safe and compelling landing sites, locate potential resources (with special attention to the possibility of water ice) and characterize the effects of prolonged exposure to the lunar radiation environment. In addition to its exploration mission, LRO will also return rich scientific data that will help us to better understand the moon’s topography and composition.
Seven scientific instruments outfit LRO. These instruments will return lunar imagery, topography, temperature measurements and more.
Launched along with LRO was the Lunar CRater Observation and Sensing Satellite (LCROSS), a partner mission that will search for water ice on the moon.
In response to LRO's "Send Your Name to the Moon" initiative, the spacecraft carries a microchip with nearly 1.6 million names submitted by the public. Click here to view a photo of the microchip containing the names as engineers prepare to install it on the spacecraft.
