Billions of years ago, Mars may have resembled Earth more closely than it does today.
The big news about Mars, as you have probably heard, is that there is liquid water on the surface.
A lunar eclipse will be visible over the Walla Walla Valley on Sunday night — but not a normal one. It will be a supermoon lunar eclipse.
From time to time the rover Curiosity uses its Mars Hand Lens Imager to take a self-portrait. These “selfies” are often taken at rock drill sites.
