Five faces of Pho­bos

All About Space - - Launch Pad -

Mars has two moons, Pho­bos and Deimos, and they are rel­a­tively tiny in com­par­i­son to our own nat­u­ral satel­lite. Pho­bos is only 22 kilo­me­tres (14 miles) in di­am­e­ter and, of the pair, or­bits the clos­est to the Red Planet.

ESA’s Mars Ex­press space­craft was able to im­age Pho­bos in five dif­fer­ent chan­nels us­ing its High Res­o­lu­tion Stereo Cam­era. The cen­tre im­age used the nadir chan­nel, the images to the left and right used two pho­tom­e­try path­ways and the outer two shots used the stereo chan­nels. These shots will al­low as­tronomers to make im­proved mod­els of Mars’ clos­est and largest satel­lite.
