The Visual Monitoring Camera (VMC) is mounted on Mars Express, ESA's deep-space probe now orbiting the Red Planet. It originally provided simple, low-tech images of Beagle lander separation, and is now back in action as the 'Mars Webcam'.
It's not a scientific instrument, but it does provide fantastic views of Mars - including crescent views of the planet not obtainable from Earth.
