The Strange Sight Of A Solar Eclipse On Mars
Here’s what the rover saw on March 26, as the Martian moon Phobos crossed the face of the sun. The image of Phobos was taken with Curiosity’s Mast Camera, with a special solar filter attached (kind of like the solar eclipse glasses you’d use to look at the sun on Earth). The Martian moon Phobos’s orbit is nearly directly over its equator; our moon, on the other hand, is in a tilted orbit, so the Earth, sun, and moon don’t line up as often.
