An ancient impact depression under the surface regolith layer of Deimos, one of several made clearer thanks to stereoscopics image produced by Sir Brian May, a member of Hera's science team.
Simulations suggest a 320-meter asteroid reshaped Deimos without destroying it, burying older craters beneath fallen debris.
