LRO Mission Overview Flight Plan – Direct using 3-Stage ELV Launch in late 2008 on a Delta II rocket into a direct insertion trajectory to the moon. On-board propulsion system used to capture at the moon, insert into and maintain 50 km altitude circular polar reconnaissance orbit. 1 year mission Orbiter is a 3-axis stabilized, nadir pointed spacecraft designed to operate continuously during the primary mission.

LRO Mission Overview Orbiter LRO Instruments Lunar Orbiter Laser Altimeter (LOLA) Measurement Investigation – LOLA will determine the global topography of the lunar surface at high resolution, measure landing site slopes and search for polar ices in shadowed regions. Lunar Reconnaissance Orbiter Camera (LROC) – LROC will acquire targeted images of the lunar surface capable of resolving small-scale features that could be landing site hazards, as well as wide-angle images at multiple wavelengths of the lunar poles to document changing illumination conditions and potential resources. Lunar Exploration Neutron Detector (LEND) – LEND will map the flux of neutrons from the lunar surface to search for evidence of water ice and provide measurements of the space radiation environment which can be useful for future human exploration. Diviner Lunar Radiometer Experiment – Diviner will map the temperature of the entire lunar surface at 300 meter horizontal scales to identify cold-traps and potential ice deposits. Lyman-Alpha Mapping Project (LAMP) – LAMP will observe the entire lunar surface in the far ultraviolet. LAMP will search for surface ices and frosts in the polar regions and provide images of permanently shadowed regions illuminated only by starlight. Cosmic Ray Telescope for the Effects of Radiation (CRaTER) – CRaTER will investigate the effect of galactic cosmic rays on tissue-equivalent plastics as a constraint on models of biological response to background space radiation.

LRO Requirements Mission SRR held 9/16-17/2005 – judged very successful Review covered development and flow down of level 2 and 3 requirements from the NASA ESMD Level 1 requirements Instruments presented flow down of Level 1 measurement and data product requirements to their level 2 and 3 performance and functional requirements Project presented flow down of level 2 and 3 mission, spacecraft, and ground system requirements ~ 50 RFAs/Comments, none specific to instruments. Level 1 requirements being refined by ESMD with Project and assistance. Ongoing work includes establishment of Mission Success Criteria SRR demonstrated that instrument requirements are established, understood, and realizable.
