• Provide early information for human missions to the Moon – Focus on unknowns associated with the North and South Poles – likely destinations for a lunar outpost • Increase capability and sustainability through strategic priorities: – Good quality topographical global map – Surface temperature and illumination characteristics – Resource distribution to overlay map – Radiation environment – Search for presence of water in permanently shadowed craters at lunar poles
3 QuickTime™ and a TIFF (Uncompressed) decompressor LRO Mission Overview are needed to see this picture.
• Launch in late 2008 on a Atlas V into a direct insertion trajectory to the moon. Co-manifested with LCROSS lunar impacter mission.
• On-board propulsion system used to capture at the moon, insert into and maintain 50 km mean altitude circular polar reconnaissance orbit.
• 1 year mission with extended mission options.
• Orbiter is a 3-axis stabilized, nadir pointed spacecraft designed to operate continuously during the primary mission.
• Investigation data products delivered to Planetary Data Systems (PDS) within 6 months of primary mission completion.

• The deposits at the north appear to be in the
) form of many small pockets which average o about 100 ppm above the equatorial hydrogen content. o The spatial resolution of the spectrometer was on the order of 50 to North Pole (>70 North Pole 150 km, insufficient to resolve surface features associated with the hydrogen signature. ) o • The deposits in the permanently-shaded craters near the south are consistent with a thick soil containing an enhancement of 1670±890 ppm hydrogen.

• The LCROSS Mission is a Lunar Kinetic Impactor employed to investigate the presence & nature of water ice on the Moon
– LCROSS is a 1000kg secondary payload riding on LRO launch vehicle in late 2008 – LRO/LCROSS will launch on an Atlas V – LRO separates and LCROSS utilizes lunar gravity-assist to establish a high-ecliptic inclination, 3-4 month cruise orbit – LCROSS separates from 2300kg Centaur stage, to enable LCROSS to observe impact and measure ejecta plume – Centaur expected to excavate ~200 metric tons of regolith, leaving a crater the size of ~1/3 of a football field, ~15 feet deep. – The S-S/C becomes a ~700kg 'impactor' as well – Ground and space-based observation being organized 10 QuickTime™ and a TIFF (Uncompressed) decompressor Mission Goals are needed to see this picture.
Perform first “in-situ” analysis of regolith from a permanently shadowed region Science goals: • Confirm the presence or absence of water ice in a permanently shadowed region on the Moon • Identify the form/state of hydrogen observed by at the lunar poles • Quantify, if present, the amount of water in the lunar regolith, with respect to hydrogen concentrations • Characterize the lunar regolith within a permanently shadowed crater on the Moon
