Artist's conception of the March 17, 2013 lunar impact as seen from near the impact site in Mare Imbrium.This video is also available on our YouTube channel. Artist's conception of the March 17, 2013 lunar impact as seen from Earth. Video of the March 17 impact taken by the lunar impact monitoring program at NASA Marshall Space Flight Center, registered to a visualization of the Moon as it appeared at the time of the impact. The video has been slowed by a factor of 3. Before and after images from the Lunar Reconnaissance Orbiter narrow-angle camera showing the new crater formed by the March 17 impact. This pair is at the original resolution of roughly 1.3 meters per pixel. The before image is cropped from M183689789L taken February 12, 2012. The after image is from M1129645568L taken July 28, 2013. Before and after images from the Lunar Reconnaissance Orbiter narrow-angle camera showing the new crater formed by the March 17 impact, centered on the crater and magnified 4x from the original resolution of roughly 1.3 meters per pixel. The before image is cropped from M183689789L taken February 12, 2012. The after image is from M1129645568L taken July 28, 2013. An animated illustration of a few of the new crater sites found by the Lunar Reconnaissance Orbiter camera team. On March 17, 2013, a NASA telescope that monitors the night side of the Moon recorded a bright flash in Mare Imbrium, at about 21°N, 24°W. The flash was one of the brightest ever recorded, and it was caused by the impact of a meteoroid estimated to be roughly a foot (30 to 40 cm) wide and just under a hundred pounds (40 kg), hitting the Moon at 60,000 miles per hour (25 km/sec).A few months after the impact, the Lunar Reconnaissance Orbiter (LRO) camera team (LROC) found the crater formed by the impact. They compared LRO images taken before and after the impact and found a new crater 18 meters (60 feet) wide, with rays of ejecta that extend several kilometers.

VISUALIZATION - Map of present-day lunar impact craters Planetary scientists believe that small impacts regularly bombard the Moon, but until recently, they’ve had no way to distinguish new craters from the already pockmarked lunar surface. In 2009, NASA’s Lunar Reconnaissance Orbiter (LRO) arrived at the Moon and began taking high-resolution photographs. By comparing pictures taken early in the mission with more recent images, the LRO camera team has discovered more than two-dozen new impact craters – including an 18-meter-wide crater caused by a bright flash on March 17, 2013.Learn more about this finding.
