LADEE, about the size as a refrigerator, crashed 780 meters from the eastern edge of the crater Sun


The space probe Lunar Reconnaissance Orbiter (LRO) NASA has spied on the formation of a new crater on the Moon, generated by the impact of connecting to the moon LADEE. The probe LADEE had ended its mission in April of this year with a dramatic dip in the lunar surface. Until now, however, its impact site was never found.

"Recently, scientists at the head of LRO have developed a new digital tool to look for pairs of images taken by the Narrow Angle Camera before to the moon and after the formation to the moon of new craters, and find the impact of a test LADEE was very funny," said Mark Robinson of the University of Arizona.
With this new software, the scientists were able to identify a crater just over three meters in diameter generated by the impact of the probe LADEE. The mission was completed April 18, a week after the probe had turned on its engines for the last time and began a rapid descent to the side of the Moon.
LADEE, about the size as a refrigerator, crashed 780 meters from the eastern edge of the crater Sundman V, an impact crater 19 kilometers wide. The crash of LADEE happened to 2590 meters above sea level, and just 300 meters north of the site provided by engineers. From the crater created by the American probe comes off a long trail of debris that stretches for 295 meters to the north-west.
The images taken by the camera aboard LRO NAC have an impressive resolution, approximately 250 megapixels. Identify a crater so small in pictures so large would have been an inhuman: for this reason, researchers have preferred to write software to the moon that would take two images of the same region in the view at different times and sottraesse to the moon between them, and this highlights the differences.
"I am pleased that the LRO team has been able to confirm the point of impact of LADEE," said Butler Hine, head of the probe that crashed earlier this year against our celestial companion. "This data will help the team LADEE to know exactly where the results of their hard work are over."
LADEE was taken off October 6, 2013 at a time of the Moon to collect important data on its atmosphere. LRO, instead, took off September 18, 2009, but the quality of his images remains unmatched.
