A promontory nicknamed "Cape Verde" can be seen jutting out from the walls
of Victoria Crater in this false-color picture taken by the panoramic
camera on NASA's Mars Exploration Rover Opportunity. The rover took this
picture on martian day, or sol, 1329 (Oct. 20, 2007), more than a month
after it began descending down the crater walls -- and just 9 sols shy
of its second Martian birthday on sol 1338 (Oct. 29, 2007). Opportunity
landed on the Red Planet on Jan. 25, 2004. That's nearly four years ago on
Earth, but only two on Mars because Mars takes longer to travel around the
sun than Earth. One Martian year equals 687 Earth days.
This view was taken using three panoramic-camera filters, admitting light
with wavelengths centered at 750 nanometers (near infrared), 530
nanometers (green) and 430 nanometers (violet).
