First Ever Hi-Res image of Deimos and Phobos released

The European Space Agency’s Mars Express orbiter snapped a series of images of the two diminutive moons on Nov. 5 and released the pictures today.
This is the first hi-res image of the martian moons Phobos and Deimos caught on camera together. These unique images will help the HRSC team validate and refine existing orbit models of the two moons. Phobos, the larger of the two moons, orbits closer to the Red Planet, circling it every 7 hours and 39 minutes. It travels faster relative to Mars than the Moon relative to Earth. It was 11 800 km from Mars Express when the images were taken. Deimos was 26 200 km away. This is not the first image as previously in 2005 Spirit took an image which captured both moons in low resolution.

Here is the new image, raw and processed which was years in the planning.

There is also a youtube video showing the motion of the two moons.

Mars Express has also taken over 100 images of the Martian Moons including these stunners.
