Lunar Reconnaissance Orbiter (LRO): Mapping the Moon and Exploring its Potential

The Lunar Reconnaissance Orbiter (LRO) is a NASA mission that aims to map the moon, evaluate its radiation environment, and search for potential resources. Launching in 2009, LRO will provide detailed 3D lunar maps, assess landing site features, and study the presence of water ice in the polar regions. With a variety of science instruments, LRO will contribute to future space exploration missions.

Presentation Transcript

  1. The Lunar Reconnaissance Orbiter (LRO) is the first mission in NASA's Vision for Space Exploration, a plan to return to the moon and then to travel to Mars and beyond. LRO will launch in early 2009 with the objectives to finding safe landing sites, locate potential resources, characterize the radiation environment, and demonstrate new technology.

  2. The spacecraft will be placed in low polar orbit (50 km) for a 1-year mission. LRO will return global data, such as day-night temperature maps, a global geodetic grid, high resolution color imaging and the moon's UV albedo.

  3. However there is particular emphasis on the polar regions of the moon where continuous access to solar illumination may be possible and the prospect of water in the permanently shadowed regions at the poles may exist.

  4. Launch date February 27, 2009 The LRO will take approximately four day’s to enter orbit around the moon. Supply information on the Lunar radiation environment. Evaluating the biological impacts and allowing development of protective technologies. Provide the first highly accurate 3D lunar maps. Map mineralogy across the whole moon. Search for polar volatiles (especially water ice). Provide sub-meter resolution imaging (including permanently shadowed regions). Provide an assessment of features for landing sites. What will LRO give us:

  5. Although the objectives of LRO are explorative in nature, the payload includes instruments with considerable heritage from previous planetary science missions, enabling transition, after one year, to a science phase under NASA's Science Mission Directorate.

  6. CRaTER Cosmic Ray Telescope for the Effects of Radiation. DLRE Diviner Lunar Radiometer Experiment. LAMP Lyman-Alpha Mapping Project. LEND Lunar Exploration Neutron Detector. LOLA Lunar Orbiter Laser Altimeter. LROC Lunar Reconnaissance Orbiter Camera. Mini-RF Miniaturized Single Aperture Radar. Science Instruments

  7. CRaTER (Cosmic Ray Telescope for the Effects of Radiation) will investigate the effects of galactic cosmic rays and solar energetic particles on tissue-equivalent plastics. CRAER will characterize the deep space radiation environment and provide a baseline to the amount of radiation humans could be exposed to.

  8. DLRE (Diviner Lunar Radiometer Experiment) will measure lunar surface temperature profiles. DLRE measurements will characterize thermal environments for habitability, determine rock abundances at landing sites by mapping nighttime surface temperatures, and map variants in silicate mineralogy. DLRE will chart the temperature of the entire lunar surface to identify cold traps and potential ice deposits.

  9. LAMP (Lyman-Alpha Mapping Project) will map the entire lunar surface in the far ultraviolet, providing images of permanently shadowed regions that are illuminated only by starlight. LAMP will search for surface ice and frost in the polar regions. LAMP is first demonstration of the same technology used by military night vision that can be applied to space exploration.

  10. LEND (Lunar Exploration Neutron Detector) will provide global mapping of the hydrogen content on the lunar surface. LEND measurements will also help characterize the neutron component of the lunar radiation environment. These measurements will also be used to search for evidence of water ice on the lunar surface.

  11. LOLA (Lunar Orbiter Laser Altimeter) will measure the precise distance between the spacecraft and the lunar surface. LOLA measurements will determine the global topography of the lunar surface at high resolution, landing site slopes, surface roughness, and possible polar surface ice in shadowed regions. LOLA will be utilized by Goddard Space Flight Center’s ground station laser ranging system to monitor the spacecraft orbit. This represents a historic first in that a laser ranging system is utilized to routinely monitor a satellite in a non-terrestrial orbit.

  12. LROC (Lunar Reconnaissance Orbiter Camera) will acquire targeted narrow angle images of the lunar surface capable of resolving meter-scale features to support landing site selection. LROC will also provide wide angle images to characterize polar illumination conditions that may identify potential resources.

  13. MINI-RF Is a technology demonstration of a miniaturized Single Aperture Radar capable of measurements at two different wavelengths. MINI-RF primary goal is to search for subsurface water ice deposits. In addition, it will take high-resolution images of permanently shadowed regions.
