Before and After Occultation of Deimos by Phobos

September 4, 2013
These six images from NASA's Mars rover Curiosity show the two moons of Mars moments before (left three) and after (right three) the larger moon, Phobos, occulted Deimos on Aug. 1, 2013. On each side, the top image is earlier in time than the ones beneath it. Curiosity used the telephoto-lens camera of its two-camera Mast Camera (Mastcam) instrument to record this occultation.
