Valles Marineris from Mars Express

Looking down from orbit on January 14, ESA's Mars Express spacecraft scanned
a 1700 by 65 kilometer swath across Valles Marineris, the Grand Canyon of Mars,
with its remarkable High Resolution Stereo Camera. This spectacular picture
reconstructs part of the scanned region from the stereo colour image data recording
the rugged terrain with a resolution of 12 metres per pixel. Joining Mars Global
Surveyor and Mars Odyssey, Mars Express has been orbiting the red planet since
December 25th, returning scientific data, acting as a communications relay, and
even making coordinated atmospheric observations with NASA's Spirit rover on the
surface. The Beagle 2 lander was released from Mars Express making a landing attempt
also on December 25th, but no signal has been received so far.
