ESA released new images of Mars' moon Phobos, taken during the Mars Express March 7, 2010 flyby, showing the rocky moon in exquisite detail and also in 3-D. Mars Express orbits the Red Planet in a highly elliptical, polar orbit that brings it close to Phobos every five months, and it is the only spacecraft currently in orbit around Mars whose orbit reaches far enough from the planet to provide a close-up view of Phobos. Like our Moon, Phobos always shows the same side to the planet, so only by flying outside the orbit is it possible to observe the moon's far side. Mars Express did such flybys on March 7, 10 and 13. Get out your 3-D glasses for a great look at Phobos, below.
