On Aug. 20, 2013, the Curiosity rover looked up from the Martian surface and saw an eclipse like you’ve never seen on Earth. The tiny moon Phobos passed in front of the sun, although the 14-mile wide moon is too small to cover it completely. And since Phobos is only 3,700 miles up (compared to our moon, which is 239,000 miles from Earth), the irregular shape of the satellite is visible. Phobos is on a trajectory that will eventually result in its death spiral, which you can read about at NPR. -via Digg
