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 early 2004, 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 and Spirit have now spent over
four years exploring the red world,
find new clues into the wet ancient past of our Solar System's second
most habitable planet.
