SPIRIT UPDATE: Leaving Middle Ground - sol 61, Mar 06, 2004
After more than a week of camping and field work at "Middle Ground,"
NASA's Spirit took a few last pictures from there then drove onward to
the northeast on sol 61, which ended at 9:51 p.m. Friday, PST. In the
martian morning, Spirit's panoramic camera took the final frames needed
for the camera team to assemble a full-circle color panorama after all
the data reaches Earth.
In the early afternoon, Spirit backed up 0.5 meter (20 inches), then
edged forward 0.29 meters (11 inches) to sidestep a rock called
"Ingrid." Then the rover advanced 28.5 meters (94 feet) toward its
crater-rim destination. The drive took 45 minutes. From the new
location, Spirit took forward-looking pictures for use in future drive
planning. It also observed the ground and the sky with its miniature
thermal emission spectrometer.
For the sol's theme tune in the morning, controllers at JPL played
"Motor Away" by Guided by Voices.
Continued driving toward the crater nicknamed "Bonneville" is the plan
for Spirit's 62nd sol, ending at 10:30 p.m. Saturday, PST.

OPPORTUNITY UPDATE: Precision Driving after Mid-Sol Science - sol 41,
Mar 06, 2004
In its 41st sol on Mars, ending at 10:02 a.m. Saturday, PST, NASA's
Opportunity inspected a rock target called "Wave Ripple" with tools on
its arm, then drove to a new target. The new target, "Flat Rock," is in
the "Slick Rock" area near the south end of the outcrop that the rover
has been examining for weeks.
Although the rover wheels slip some in the local soil and the drive
traversed a slope of 10 to 11 percent, Opportunity and engineers at JPL
navigated the trip so well that a planned final approach to the target
on sol 42 could be cancelled. The target is within the work volume of
Opportunity's robotic arm. The drive was done in a series of one-meter
(3.3-foot) segments making up a U-shaped path to the south and west.
Each segment included a correction for slippage.
Before starting the drive, Opportunity used its microscope for 50 images
of "Wave Ripple," and examined the composition of the rock with its
alpha proton X-ray spectrometer and its Moessbauer spectrometer.
Rover controllers spun Willie Nelson's "On the Road Again" as the sol's
wake-up song, and used a compressed planning schedule as practice for
procedures that might become standard after the 90-sol prime mission.
Plans for sol 42, ending at 10:51 a.m. Sunday, PST, include using the
rock abrasion tool at "Flat Rock."
