Explanation: What if you saw your shadow on Mars and it wasn't human (http://www.nlm.nih.gov/research/visible/visible_human.html)? Then you might be the Opportunity rover (http://marsrovers.jpl.nasa.gov/overview/) currently exploring Mars. Opportunity and sister robot Spirit (http://antwrp.gsfc.nasa.gov/apod/ap040122.html) have been probing the red planet (http://www.nineplanets.org/mars.html) since early 2004, finding evidence of ancient water (http://antwrp.gsfc.nasa.gov/apod/ap040303.html), and sending breathtaking images across the inner Solar System (http://www.nineplanets.org/overview.html). Pictured above (http://www.jpl.nasa.gov/missions/mer/images.cfm?id=738), Opportunity looks opposite the Sun into Endurance Crater (http://antwrp.gsfc.nasa.gov/apod/ap040510.html) and sees its own shadow (http://antwrp.gsfc.nasa.gov/apod/ap990830.html). Two wheels are visible on the lower left and right, while the floor and walls of the unusual crater are visible (http://photojournal.jpl.nasa.gov/catalog/PIA06739) in the background. Opportunity and Spirit have now spent over four years (http://www.jpl.nasa.gov/multimedia/podcast/mer20070117/) exploring the red world, find new clues into the wet ancient past of our Solar System's second most habitable planet (http://antwrp.gsfc.nasa.gov/apod/ap000102.html).
