Nereus Crater on Mars

Explanation: It was along the way. The robotic rover Opportunity currently rolling across the Meridiani Plain on Mars has a destination of Endeavour Crater, a large crater over 20 kilometers across which may yield additional clues about the cryptic past of ancient Mars. Besides passing open fields of dark soil and light rock, Opportunity has chanced upon several interesting features. One such feature, pictured above in a digitally stitched and horizontally compressed panorama, is Nereus Crater, a small crater about 10 meters across that is surrounded by jagged rock. Besides Nereus, Opportunity recently also happened upon another unusual rock -- one that appears to be the third large meteorite found on Mars and the second for Opportunity during only this trip. Opportunity has been traveling toward Endeavour Crater for over a year now, and if it can avoid ridged rocks and soft sand along the way, it may reach Endeavour sometime next year.

These pictures are marvelous, thanks for posting. This one made me think of C.S. Lewis' Out of the Silent Planet and his other science fiction. I wonder what he would be writing today had he been able to view these photographs.

Heh. I know that place. I think we did a few weeks of training there a couple decades ago.

I’m pretty sure that hole was our company CP for a few days.

Maybe you were the guys who planted the flag up there on Mars and Sheila Jackson Lee (D-Tx) got you mized up with Neil Armstrong planting the flag on the Moon...

Wow! Looks like a giant dark chocolate dessert—pun intended—with lots of nuts.
