Mission planners for NASA's Spirit rover on Mars are using this view from above
to help plan the remainder of the robot's travels. It shows the Columbia Hills
in Gusev Crater.
The picture was made by draping an image from NASA's Mars Global Surveyor over
a digital elevation model that was derived from two other images from the orbiter.
As of sol 135, or May 21, 2004 on Earth, Spirit sat approximately 0.4 miles
(680 meters) away from its first target at the western base of the hills, a
spot informally called West Spur. The team estimates that Spirit will reach
West Spur by sol 146, or June 1, 2004. Spirit will most likely remain there
for about a week to study the outcrops and rocks associated with this location.
When done there, Spirit will head approximately 0.38 miles (620 meters) to
a higher-elevation location informally called Lookout Point. Spirit might reach
Lookout Point by around sol 165 (June 20, 2004). On the way, the rover will
pass by and study ripple-shaped wind deposits that may reveal more information
about wind processes on Mars.
Lookout Point will provide a great vantagepoint for scientists to remotely
study the inner basin area of the Columbia Hills, according to a statement released
last week. This basin contains a broad range of interesting geological targets
including Home Plate and other possible layered outcrops. These features suggest
that the hills contain rock layers. Spirit might investigate the layers to determine
whether they are water-deposited sedimentary rock.
