SPIRIT UPDATE: Spirit Continues to Drive - sol 110-111, Apr 27, 2004
After a successful weekend of driving on sols 108 and 109, Spirit kicked
off its week with a 140-meter (459.3 feet) drive over sols 110 and 111
toward its destination at the base of the "Columbia Hills."
Spirit began sol 110, which ended at 7:10 a.m. PDT on April 25, 2004,
with a stretch of its "arm" to take microscopic imager pictures of an
area of soil called "Waffle Flats." It then placed the Moessbauer
spectrometer instrument on that spot for a 90-minute integration. Spirit
did double-duty and was able to get panoramic camera and mini thermal
emission spectrometer images of the area for localization and science
purposes while the Mössbauer was at work.
Spirit then stowed its instrument deployment device and began an
80-meter (262.5 feet) drive, half of it directed by rover planners and
half using the autonomous navigation software. During the autonomous
navigation portion, the rover detected a hazard and did not complete the
final short-drive intended at the end of the journey. Images from the
front hazard avoidance camera show no sign of a hazard, leaving rover
controllers with a bit of a mystery to investigate.
Following the drive, Spirit took panoramic camera and navigation camera
images in the drive direction and performed atmospheric science with the
panoramic camera and mini thermal emission spectrometer.
Sol 111, which ended at 7:50 a.m. PDT on April 26, 2004, was also a sol
full of driving for Spirit. After acquiring panoramic camera images of
its surroundings and completing atmospheric science with the panoramic
camera and mini thermal emission spectrometer, the rover began its drive.
Spirit successfully completed a 60.8-meter (199.5 feet) drive toward the
Columbia Hills and then acquired navigation and panoramic camera images
of the driving direction. Spirit ended the day with mini thermal
emission spectrometer observations of the soil and then a coordinated
mini thermal emission spectrometer and panoramic camera study of the
atmosphere.

OPPORTUNITY UPDATE: Opportunity Achieves Mission Success! - sol 90-91,
Apr 27, 2004
With 811.57 meters (a little over one half of one mile) on its odometer,
12,429 images downloaded and a record for the longest one-sol drive
under its belt, Opportunity completed its prime mission. Finishing 90
sols of surface operations since landing day marked completion of the
last of the official success criteria for Opportunity's prime mission.
On sol 90, the rover continued with the multi-sol panoramic camera and
miniature thermal emission plains photometry observations. The alpha
particle X-ray spectrometer was busy collecting data on the soil targets
"Nougat" and "Fred Ripple."
On sol 91, Opportunity completed more remote sensing and took a
Moessbauer spectrometer read on Fred Ripple. The rest of the sol was
spent driving. A 40-meter (131.2 feet) drive in the southeasterly
direction left Opportunity only 160 meters (about 525 feet) from the rim
of "Endurance Crater."
