Lutetias dark side hosts hidden crater

Grooves found on Lutetia, an asteroid encountered by ESAs Rosetta spacecraft, point to the existence of a large impact crater on the unseen side of the rocky world.
Rosetta flew past Lutetia at a distance of 3168 km in July 2010, en route to its 2014 rendezvous with its target comet.
The spacecraft took images of the 100 km-wide asteroid for about two hours during the flyby, revealing numerous impact craters and hundreds of grooves all over the surface.
