Deimos measures just over 7 miles across. Scientists believe Deimos could be a leftover chunk from Mars or a gravitationally captured asteroid, according to the ESA. "These instruments have been ...

Mars has two moons, named Phobos and Deimos, but because Phobos is closer to Mars, it has been previously imaged by other spacecraft. "For Deimos, we don't have as many images as Phobos ...
