What eight dusty years on Mars will do to a rover. This pair of self-portaits from NASA's Mars Exploration Rover Opportunity shows dust accumulation on the rover's solar panels as the mission approaches its fifth Martian winter. The dust reduces the rover's power supply, and the rover's mobility is limited until the winter is over or wind cleans the panels. The photo on the left side was taken in February of 2005, when Opportunity had only been on the planet for 322 Martian days (sols). The right side was taken in December of 2011, after some 2,800 sols. Total distance driven by Opportunity to date: 34.36 km (21.35 miles) (NASA/JPL) # http://cdn.theatlantic.com/static/infocus/i/lnk.jpg

In the foreground, the high-gain antenna aboard NASA's Rover Opportunity, as the robotic probe has positioned itself on the rim of Endeavour Crater with an approximate 15-degree northerly tilt for favorable solar energy production during the Martian winter. While positioned for the winter, Opportunity is conducting regular radio Doppler tracking measurements to support geo-dynamic investigations of the planet.

This image obtained by the framing camera on NASA's Dawn spacecraft shows the south pole of the giant asteroid Vesta. The image was recorded with the framing camera aboard NASA's Dawn spacecraft from a distance of about 2,700 km (1,700 mi).

An image of the giant asteroid Vesta, obtained by NASA's Dawn spacecraft as it was spiraling down from its high altitude mapping orbit to low altitude mapping orbit, on November 27, 2011. NASA announced December 12 that the spacecraft successfully maneuvered into its closest orbit around the giant asteroid Vesta, beginning a new phase of science observations. The spacecraft is now circling Vesta at an altitude averaging about 210 km (130 mi). (Reuters/NASA/JPL-Caltech) # http://cdn.theatlantic.com/static/infocus/i/lnk.jpg
