The rover Curiosity gets a look at an an annular eclipse on Mars as Phobos passes in front of the Sun. Phobos is the larger of the two Martian moons.
In case you are wondering:
The next solar eclipse for us here on Earth will be on 03 November 2013. The very eastern part of the US might see it just after daylight, if you are on a ship in the Atlantic you should be able to catch it as well as southern Europe (Spain mostly) and much of central Africa. More about that when the event gets closer.
This set of three images shows views three seconds apart as the larger of Mars’ two moons, Phobos, passed directly in front of the sun as seen by NASA’s Mars rover Curiosity. Curiosity photographed this annular, or ring, eclipse with the telephoto-lens camera of the rover’s Mast Camera pair (right Mastcam) on Aug. 17, 2013, the 369th Martian day, or sol, of Curiosity’s work on Mars.
