Enhanced Radar Imagery of Lunar South Pole
Media Briefing 2 p.m. Eastern/11 a.m. Pacific
02.27.08
NASA has obtained the highest resolution terrain mapping to date of the moon’s rugged south polar region. Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., generated the imagery using data collected with the facility's Goldstone Solar System Radar.

Libration Movie
The moon's orbit is not perfectly circular its rotation axis is tilted with respect to Earth allowing scientists to image slightly different parts of the Moon during a its 28 day long lunar day. This movie shows the portion of the Moon visible to the Earth over several months around the time when radar data of the south polar region of the Moon was collected.
Earth and moon comparison

Earth Moon Contact
Radar signals from the Goldstone Solar system Radar are reflected back to Earth and received at two antennas separated by 13 kilometers. By receiving at the two antennas, three dimensional topographic maps of the lunar surface can be generated.

Digital Elevation Map of Lunar South Pole
Image brightness is generated from the strength of the radar echoes that are bounced of the lunar surface and the color represents the elevation. This map covers an area of 650 kilometers by 450 kilometers with an elevation measurement every 40 meters.

South Pole Zoom In
Starting from a wide area map of the lunar south pole we progressively zoom into the region around Shakleton Crater.

Slope Map
This map shows the steepness of the terrain in the south polar region of the moon. Using a map like this helps determine the assessable areas to human or robotic explorers.

High Resolution Slope Map
The left image shows the topographic contours in color with each cycle of color representing 2 kilometers of elevation change. The right image is the corresponding slope map of the area. The slope map indicates slopes in excess of 20 degrees in the region around Shakleton Crater.

Lunar Landing Animation
This animation utilizes the latest terrain data of the moon's south pole region in the generation of a animation of what a future moon crew could see during a descent to the rim of Shackleton Crater.
