On March 7 the Mars Express satellite, operated by the European Space Agency (ESA), performed a flyby of Mars' tiny moon Phobos. My current image of the week, captured by the German Aerospace Center's High Resolution Stereo Camera (HRSC) aboard Mars Express, provides the best details yet of the Moon.

Images like these are important as Russia is set to launch a mission to land an unmanned craft on the Moon in 2011, and details of the probable landing site is an important step. Like our Moon, Phobos is rotationally locked to its host world -- meaning that Phobos rotates once during each orbit of Mars -- so the same side of the planet is always facing the surface. Since most probes to the "red planet" follow a shallow orbit, and don't extend out to the orbit of Phobos, getting detailed images of the "dark side" of Phobos is difficult. However, since Mars Express follows a highly elliptical orbit it will periodically pass close to Phobos and can take such detailed images. Enjoy the image of the week.
