NASA'S Mars Exploration Rover Spirit captured this westward view from atop
a low plateau where Sprit spent the closing months of 2007.
After several months near the base of the plateau called "Home Plate" in
the inner basin of the Columbia Hills range inside Gusev Crater, Spirit
climbed onto the eastern edge of the plateau during the rover's 1,306th
Martian day, or sol, (Sept. 5, 2007). It examined rocks and soils at
several locations on the southern half of Home Plate during September and
October. It was perched near the western edge of Home Plate when it used
its panoramic camera (Pancam) to take the images used in this view on sols
1,366 through 1,369 (Nov. 6 through Nov. 9, 2007). With its daily
solar-energy supply shrinking as Martian summer turned to fall, Spirit
then drove to the northern edge of Home Plate for a favorable winter
haven. The rover reached that northward-tilting site in December, in time
for the fourth Earth-year anniversary of its landing on Mars. Spirit
reached Mars on Jan. 4, 2004, Universal Time (Jan. 3, 2004, Pacific
Standard Time). It landed at a site at about the center of the horizon in
this image.
This panorama covers a scene spanning left to right from southwest to
northeast. The western edge of Home Plate is in the foreground, generally
lighter in tone than the more distant parts of the scene. A rock-dotted
hill in the middle distance across the left third of the image is
"Tsiolkovski Ridge," about 30 meters or 100 feet from the edge of Home
Plate and about that same distance across. A bump on the horizon above the
left edge of Tsiolkovski Ridge is "Grissom Hill," about 8 kilometers or 5
miles away. At right, the highest point of the horizon is "Husband Hill,"
to the north and about 800 meters or half a mile away.
This view combines separate images taken through Pancam filters centered
on wavelengths of 753 nanometers, 535 nanometers and 432 nanometers to
produce an approximately true-color panorama.
