This is a truely imspiring image of Earth as seen by a Nasa spacecrafts currently orbiting Mars. This photo is a mix of visual and InfraRed images and apparently took quite a bit of effort to produce.   Currently Nasa have a mission to take high resolution images of Mars using the HiRISE instrument (High Resolution  Imaging Science Experiment). The HiRISE is aboard the MRO (Mars Reconnaissance Orbiter) and took some time out to snap a lovely picture of Earth.
