  1. LRO SRR LRO Mission Overview

  2. 2008 Lunar Reconnaissance Orbiter (LRO)First Step in the Robotic Lunar Exploration Program LRO Objectives • Characterization of the lunar radiation environment, biological impacts, and potential mitigation. Key aspects of this objective include determining the global radiation environment, investigating the capabilities of potential shielding materials, and validating deep space radiation prototype hardware and software. • Develop a high resolution global, three dimensional geodetic grid of the Moon and provide the topography necessary for selecting future landing sites. • Assess in detail the resources and environments of the Moon’s polar regions. • High spatial resolution assessment of the Moon’s surface addressing elemental composition, mineralogy, and Regolith characteristics

  5. LRO Mission OverviewFlight Plan – Direct using 3-Stage ELV • Launch 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.

  6. LRO Mission OverviewOrbiter 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.

  10. LRO Science Overview • LRO follows in the footsteps of the Lunar Orbiter missions which proceeded Apollo. • LRO will launch by 2008 to provide critically needed data to enable and to plan future Exploration objectives • LRO provides major exploration and scientific benefits by 2009 • Apollo provided first order information from a small region of the Moon; much more of the Moon needs to be explored • LRO objectives addresses future landing sites, polar resources, safety, and lunar science goals • LRO address both science and exploration objectives • LRO instrument suite complements international lunar missions • Six instruments competitively selected • Comparison to international missions demonstrate LRO uniqueness and value

  11. Competitively Selected LRO Instruments Provide Broad Benefits

  12. National Academy of Sciences NRC Decadal (2002) lists priorities for the MOON (all mission classes thru 2013)

  13. Comparison to International Systems Demonstrate Uniqueness and Value
