“Webcam” at Mars
Check this out. One of the engineering cameras on Mars Express (originally used to make sure that the Beagle lander had detached from the orbiter) has been turned back on! So now you can go check out the view from Mars orbit! More detail over at Bad Astronomy. The picture above shows the four giant volcanoes of the Tharsis bulge: Olympus Mons is half in shadow and the other three, left to right, are Arsia Mons, Pavonis Mons and Ascraeus Mons. North is toward the bottom right of this image.
