The Lunar Reconnaissance Orbiter Camera (LROC) has been designed to address two of the measurement requirements:

  • Landing site certification

  • Polar illumination

LROC will acquire images to assess meter and smaller scale features to facilitate safety analysis for potential lunar landing sites near polar resources and elsewhere on the Moon. Synoptic 100 m/pixel imaging of the poles during every orbit for a year will unambiguously identify regions of permanent shadow and permanent or near-permanent illumination.

In addition to these two primary objectives, LROC will return six other high-value datasets:

  • Meter-scale mapping of regions of permanent or near-permanent illumination of polar massifs

  • Multiple coregistered observations of portions of potential landing sites and elsewhere for derivation of high-resolution topography through stereogrammetric and photometric stereo analyses

  • A global multispectral data set in 7 wavelengths (300-680 nm) to characterize lunar resources, in particular ilmenite

  • A global 100- m/pixel basemap with incidence angles (60-80Á) favorable for morphologic interpretations

  • Sub-meter imaging of a variety of geologic units to characterize physical properties and variability of the regolith

  • Meter-scale coverage overlapping with Apollo era Panoramic images (1-2 m/pixel) to document the number of small impacts since 1971-1972, to ascertain hazards for future surface operations and interplanetary travel.

MDREMP

Mosaic Data Record - Empirically Normalized Wide Angle Camera Mosaic

This empirically normalized WAC mosaic was constructed from 137,400 color WAC images acquired from January 21, 2010 to January 31, 2013 over a broad range of lighting and viewing geometries. Each pixel from the WAC observations were photometrically normalized to a standard geometry of 30 degrees incidence angle, 0 degrees emission angle, and 30 degress phase angle using an empirically derived global photometric function. Nomalized WAC pixels for each location were combined using the median (average n=142), so each mosaic value is using information from many observations.

Please review the readme file!

Characterize lunar resources such as abundance of ilmenite and supports multispectral analysis of the lunar surface

MDRHAP

Mosaic Data Record - Photometrically normalized 7-color semi-global mosaic using Hapke parameter maps

Hapke photometric parameter maps (w,b,c,bc0,hc,bs0,hs,theta,phi) in 1 deg x 1 deg tiles for the 7 bands of the WAC. The mosaic was constructed from ~124,300 WAC images acquired from January 21, 2010 to May 1st, 2013. The map was normalized to the angles of phase (g) = incidence (i) = 60°, emission (e) = 0° by Hapke bidirectional reflectance function using Hapke parameter maps. The g, i, and e angles were calculated using the WAC stereo digital terrain model (GLD100). Each pixel value of this mosaic consists of a median of normalized I/F from ~40 months of repeated observations (UV:58-59, visible:136-140 observations in average).
