Lunar Datasets
• Earth Based Telescopes• Ranger• Surveyor• Lunar Orbiter• Apollo Photography
– handheld– automated
• Apollo Laser Altimetry• Apollo Elemental• Soviet Surface Imaging
• Earth Based Radar• Clementine
– Imaging, topography• Lunar Prospector
– Elemental maps• Gravity• Global Control Network
• Chang’e, Kaguya• Chandrayaan 1, LRO
Review relevant image datasets, existing and upcoming
Lunar Orbiter• Best existing global BW morphology
dataset (60 m/pix near and ~300 far m/pix)
• USGS LO negatives global map scan project “completed”
• High resolution mapping of equatorial regions (LO 1,2,3)
• Synoptic mapping (LO 4)• High-resolution coverage of science
targets (LO 5)• High Resolution LO Coverage:
– ~1m/pixel of 1% of Moon– ~10 m/pixel covers ~12%– Nearside at ~60 m/pixel– Farside ~300 m/pixel– Quality varies

Apollo Photography 1968-1972• Handheld 70-mm
– 10,000 Color– 10,000 BW– Orbit, surface
• Metric Camera (Ap 15-17)– BW, 127 x 127 mm (~8m/pixel)
• Panoramic Camera (Ap 15-17)– BW, 127 mm x 1 m (1m/pixel)
• 35-mm, Ap 14 Hycon, surface stereo…• JSC/ASU Apollo Flight Film Scanning Project underway!!
– All flight films scanned by end 2009– Accessible online at:
HTTP://apollo.sese.asu.edu
AS15-M-0284
Apollo 14 at Frau Mauro
Apollo Metric/Pan Camera Coverage
True stereo, incidence angle ranges from 90° to near 0°, simultaneous laser altimeter point (~10,000 negatives). Panoramic camera footprints very similar (~4800 negatives). Full resolution digital scan project in progress! See information in registration folder.
Clementine 1994
UVVIS NearsideHigh Sun for Color Analysis
• UVVIS (CCD)– 100-200 m/p global– 5 filters (415-1000 nm)
• NIR (InSb)– 160-320 m/p global– 6 filters (1100-2800 nm)
• HIRES (CCD)– 25-50 m/p (effective)– 4 filters (415-750 nm)– BW poles, selected color strips
• LWIR (HgCdTe)– 200-400 m/p global– broadband (8000-9500 nm)
• LIDAR Ranging (2.5° spatial, 100 m vertical, 65S to 65N)
Chang’e
• Stereo Camera 120 m/p• 200x200 km orbit• Launched Oct 2007, 1 year nominal mission
• Terrain Mapping Camera (TMC) 5 m resolution (40 km swath) global map of the Moon
• To be launched mid-2008
Chandrayaan
Kaguya (Selene)• Launched Oct. 2007, 3 spacecraft• 100 km circular polar orbit• Terrain Camera Broadband Stereo
10 m/p, +- 15° forward and aft, planned global mapping
• Multi Band Imager (20/62 m/p, VIS/NIR)
• HDTV• http://www.selene.jaxa.jp/index_e.ht
m• Data release one year from end of
nominal mission
QuickTime™ and aTIFF (LZW) decompressor
are needed to see this picture.
Earth Based Radar• 20 to 40 m/pixel imaging and topography
of lunar poles • Nearside only
• Estimate illumination conditions over time
Topography near Shackleton (S. Pole)
Lunar Reconnaissance Orbiter 2008
• LROC: Global WAC UV-VIS imaging 100 m/pixel; NAC BW 10% Moon at 0.50 m/pixel
• LOLA: Global topography• LEND: Neutron flux (water ice)• DLRE: Temp. of lunar surface• LAMP: Search for surface ices
in polar regions• CRaTER: Lunar radiation
environment• Mini-RF: SAR (image
permanently shadowed areas)
Lunar Reconnaissance Orbiter Camera• 2 Narrow Angle Cameras (NACs) for Landing Site Certification
• 1000s of potential landing site observations at 0.5 m/pix
• Polar mosaics (85.5 to 90) at 1 m/pix
• Conventional and photometric stereo observations for 2 to 10 m/pix topography
• Wide Angle Cameras (WAC) to Monitor Polar Lighting and Map Resources
• Every orbit image each pole: BW 100 m/p• Global BW 100 m/p >50° incidence coverage• Global 7-color (100/400 m/p), 10° to 40° incidence• Special Observations (context, phase experiments, stereo)
What is NeededPrior to Human Return
– Uniform global geodetic control network– Uniform global high resolution mineralogic and
compositional data– Uniform global high resolution morphology data– Uniform global regolith characterization
– Local very high resolution imaging of landing sites– Local very high resolution topography of landing
sites
