LRO carries seven instruments to study the Moon and its environment:
DLRE (Diviner Lunar Radiometer Experiment):
measures the temperature of regions on the Moon, even in the dark
LAMP (Lyman Alpha Mapping Project):
looks for water-ice on the Moon's surface
LEND (Lunar Exploration Neutron Detector):
looks for water-ice on and under the Moon's surface
LOLA (Lunar Orbiter Laser Altimeter):
measures the height of the Moon's features, such as mountains, craters, and valleys
LROC (pronounced "ell-rock;" Lunar Reconnaissance Orbiter Camera):
takes pictures of the Moon's surface to understand how it formed
Mini-RF (Miniature Radio Frequency technology demonstration):
uses radar to search for water-ice under the Moon's surface
And of course, CRaTER (Cosmic Ray Telescope for the Effects of Radiation): measures the Moon's radiation environment due to cosmic rays
