Explanation: What if you saw your shadow on Mars and it wasn't
human? Then you might be the Opportunity rover currently
exploring Mars. Opportunity and sister robot Spirit have been
probing the red planet since January, finding evidence of
ancient water, and sending breathtaking images across the inner
Solar System. Pictured above, Opportunity looks opposite the Sun
into Endurance Crater and sees its own shadow. Two wheels are
visible on the lower left and right, while the floor and walls
of the unusual crater are visible in the background. Opportunity
is cautiously edging its way into this enigmatic crater, hoping
to find new clues into the wet ancient past of our Solar
System's second most habitable planet. Authors & editors: NASA
