Goodbye, Hollows

As NASA MESSENGER enters its final days, we are getting our last looks at some of our favorite features. Hollows, discovered in MDIS images during the orbital phase of the mission, are always photogenic. Three small hollows can be spotted in this scene located to the northwest of the Caloris basin near Timgad Vallis, including one that is surrounded by low-reflectance material.
