A new high-resolution map of the moon's north pole shows a view of the surface that even the Apollo astronauts would envy.
The new lunar mosaic — which was captured by NASA's Lunar Reconnaissance Orbiter (LRO) — resolves features as small as 6.5 feet (2 meters), providing information that could be used for landing-site scouting or to answer various questions about the surface of the moon, agency officials said.
With scientists and the public able to click, zoom in and move around the map, it's the first time an interactive mosaic has been released of the moon's north pole. [See the new moon map and more lunar photos from LRO]
"Creation of this giant mosaic took four years and a huge team effort across the LRO project," Mark Robinson, principal investigator for the Lunar Reconnaissance Orbiter Camera, said in a statement.
"We now have a nearly uniform map to unravel key science questions and find the best landing spots for future exploration," added Robinson, who is based at Arizona State University in Tempe.
The mosaic is made up of 10,581 pictures carefully selected to provide consistent lighting across the surface. The map, which is hundreds of billions of pixels in size, gives a high-definition view of craters, divots and shadows across an area more than one-quarter that of the United States.
If you were to print out the map at the standard for print publications (300 dots per inch), it would be almost the same size as a U.S. football field, NASA officials said.
Images were obtained by the Lunar Reconnaissance Orbiter Camera, supplemented with data from LRO's Lunar Orbiter Laser Altimeter instrument. Map creators also used data from NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission.
GRAIL's twin spacecraft (called Ebb and Flow) made the highest-resolution gravity map ever of the moon before smashing as planned into a lunar mountain in December 2012.
NASA's Lunar Reconnaissance Orbiter has been circling the moon since June 2009, using seven instruments to examine the lunar surface and its radiation. Among the probe's notable achievements is finding extensive evidence of water iceon the moon's surface.
