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.
Several instruments that will help NASA characterize the moon's surface have been installed on LRO. The powerful equipment will bring the moon into sharper focus and reveal new insights about the celestial body nearest Earth. The LRO payload, comprised of seven instruments, will provide key data sets to enable a human return to the moon.

CRaTER will characterize the lunar radiation environment, allowing scientists to determine potential impacts to astronauts and other life. It also will test models on the effects of radiation and measure radiation absorption by a type of plastic that is like human tissue. The results could aid in the development of protective technologies to help keep future lunar crew members safe. CRaTER was built and developed by Boston University and the Massachusetts Institute of Technology in Boston.
The Diviner Lunar Radiometer Experiment (DLRE) will identify cold traps -- areas cold enough to preserve ice for billions of years -- and potential ice deposits as well as rough terrain, rock abundance, and other landing hazards. Diviner was built and developed by the University of California, Los Angeles, and NASA's Jet Propulsion Laboratory in Pasadena, Calif. Diviner will measure surface and subsurface temperatures from orbit. It will identify cold traps and potential ice deposits as well as rough terrain and other landing hazards.

Permanently shadowed regions on the moon's surface, such as the bottoms of some of the deep craters at the lunar poles, are very cold and might hold water ice. The Lyman-Alpha Mapping Project (LAMP) was built and developed at the Southwest Research Institute in San Antonio.
The Lunar Exploration Neutron Detector (LEND) will create high-resolution maps of hydrogen distribution and gather information about the neutron component of the lunar radiation environment. LEND data will be analyzed to search for evidence of water ice near the moon’s surface. LEND was developed at the Institute for Space Research in Moscow.
The Lunar Orbiter Laser Altimeter (LOLA) will measure the slope of potential landing sites and lunar surface roughness. LOLA will generate a high-resolution, 3-D map of the moon. LOLA also will measure and analyze the lunar topography to identify permanently illuminated and permanently shadowed areas. Certain mountain peaks at the lunar poles might be permanently illuminated. These regions may be good places for a solar power station. The Lunar Orbiter Laser Altimeter (LOLA) was conceived and built by scientists and engineers at NASA's Goddard Space Flight Center.

Two narrow-angle cameras on the Lunar Reconnaissance Orbiter Camera (LROC) will make high-resolution, black-and-white images of the surface, capturing images of the poles with resolutions down to 1 meter (about 3.3 feet). A third, wide-angle camera (WAC), will take color and ultraviolet images over the complete lunar surface at 100-meter (almost 330-foot) resolution. These images will show polar lighting conditions, identify potential resources and hazards, and aid selection of safe landing sites.

The Miniature Radio Frequency (Mini-RF) is an advanced radar that will be used to image the polar regions and search for water ice. In addition, it will be used to demonstrate the ability to communicate with an Earth-based ground station.
