2. 2008 Lunar Reconnaissance Orbiter (LRO) First Step in the Robotic Lunar Exploration Program

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

3. Investigation Background

LRO provides major scientific and exploration benefit by 2009
–
–
–
LRO selected instruments complement other foreign efforts
–
–
–
Six instruments competitively selected (“next-generation payload”)
Comparison to foreign systems demonstrate uniqueness and value
LRO will also accommodate a HQ directed Technology Demonstration payload, the
Mini-RF (SAR) instrument.
LRO will enhance our knowledge of the Moon and increase the safety of future
human missions.
–
–
Apollo provided only a small glimpse of Moon; much to be explored
LRO address both science and exploration objectives
LRO brings many benefits (e.g., future landing sites, polar resources, safety, science)
3D maps of terrain and hazards, as well as of localized resources (ice) will tell us where
to land (and at what precision).
Exploration of new sites where resources may be available requires new and timely
knowledge of those sites at scales never before possible.
Current state of knowledge does not allow us to reduce the risk and cost of
humans landing and working on the Moon.
–
–
Equatorial environment (terrain, thermal, lighting) is different from polar region.
Apollo Program flight system capability limited to equatorial region (capability)

LRO Instruments
INSTRUMENT
MODULE
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.

• Spacecraft Computer specified and under development on ESES contract
• SQ-RAID (hard disk) technology selected for data recorder. Acquisition now in-work.
• Subsystem technical Peer Review being conducted Sept. - November
• Approximately $15M in direct procurements planned during Sept.-Dec.
Ground Systems – architecture and acquisition approach defined

–
Mission Operations Center
• Preliminary design established based on GSFC heritage systems
• Location established, initial facility agreements in-place
Ground Network
• Requirements and architecture established
• Primary 18m antenna procurement contract in place
• GSFC Ground Networks providing end-to-end system
–

16

17. 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.
