MSL - Phobos transits Deimos (Sol 351)
MSL Section, Mission Updates
On Sol 351, Curiosity completed a very special imaging operation at night - using its Mast Cameras to photograph the two Martian Moons, Phobos and Deimos crossing paths in the sky above Gale Crater. 41 frames were acquired that were used to produce a short video of the transit. The images show Deimos as a little dot in the sky, but Phobos is shown with remarkable detail - Phobos is larger than Deimos and orbits much closer to Mars.
On Phobos, Stickney Crater can be seen on the bottom. It is on the leading hemisphere of Phobos. Hall Crater, in the south, is the prominent feature on the right hand side.
