The twin GRAIL spacecraft impacted the Moon on 17 December 2012, LROC was able to image the impact craters on 28 February 2013 showing them both to be about 5 meters in diameter. Upper panels show the area before the impact; lower panels after the impact. Arrows point to crater locations [NASA/GSFC/Arizona State University].
This image shows the lower part of the northeast inner wall of the Kepler impact crater. Loose material is sliding down the inner crater from near the rim crest (upper right) and ponding on a part of the crater floor. LROC NAC M104755664L [NASA/GSFC/Arizona State University].
Small portion of a S-shaped meandering rille on the floor of Posidonius Crater (31.93°N, 29.85°E, 100 km diameter) - a floor-fractured crater. The curves in the rille are very tight. LROC NAC M1098658474R [NASA/GSFC/Arizona State University].
