\n\tNASA declares the mission of the Lunar Reconnaissance Orbiter (LRO) a success after beaming back images and measurements in sharper detail than ever before. The LRO was launched on June 18, 2009 and its seven instruments have sent back more than 192 terabytes of data – the equivalent of 41,000 DVDs. Images recorded up to 1.5 feet per pixel – showing new details of the lunar surface.

\n\tThe smooth impact melt inside Thales crater is cracked and then sprinkled with boulders from the neighboring slope. Here’s a look at some of the images and measurements returned by the LRO.

\n\t”We needed to leverage the very best the
\n\tscience community had to offer,” said Michael Wargo, chief lunar
\n\tscientist of ESMD. “And by doing that, we’ve fundamentally changed
\n\tour scientific understanding of the moon.”

\n\tThe Lunar Reconnaissance Orbiter Camera revealed nearly 5.7 million square kilometers of the moon’s surface.
\n
\n\tIn the photo above, this crater which is located in Mare Humorum contains relatively few boulders. This means that the impact area is probably made of regolith and fragmented the underlying mare basalt into large boulders.

\n\tFor a six month period (or six lunar days) the LRO collected 1,700 images of the same area at the south pole. The binary images were then stacked to form the map above which shows the areas that never see sunlight.

\n\tThe LRO found the coldest spot in the
\n\tsolar system, with a temperature of minus 415 degrees Fahrenheit.

\n\tIs this a volcano?

\n\tIs it dry debris or liquid flow? Granular debris on the wall of Stevinus A flows downhill to the right. A 7 meter boulder impedes the progress of the flow, which bifurcates and reconnects about 10 m downhill.

\n\tThe far side of the moon. Astronauts are the only humans to ever see it in person.
\n\tThe LRO detailed new maps of lunar surface characteristics.
\n\tThis is a south polar map of enhanced hydrogen which could potentially be used as fuel.
\n\tLRO also created a radar map of the north polar region.
\n\tThe lunar poles are shown in ultraviolet light.
\n\tThe LRO captured this landslide on the wall of a small crater which slopes from the top right to the bottom left. The landslide has exposed many boulder within the crater wall.

\n\tNASA doesn’t know how pancake-like mounds like this one in thte Stevinus crater formed on a relatively flat surface. Perhaps they were formed by magma under the crust or maybe they were formed by slumping caused by small impacts over time.

\n\tThis large hole is thought to be created by a collapsed lava tube.
\n\tThe upper slopes of Diophantus crater, located on the western edge of Mare Imbrium, shows dark materials that flowed downward from the crater walls. These dark features originate from several layers exposed in the crater walls. But what are they made of and how did they get there? Volcanos?

\n\tNASA has many, many more images and videos received from the LRO.
