Update: Spirit and Opportunity
SPIRIT UPDATE: Spirit Speeds to 'Lead Foot' - sol 124-126, May 12, 2004
Spirit drove 80 meters (262.5 feet) on sol 124, bringing its total
odometry to 1,909.52 meters (1.2 miles). Spirit has less than 1.2
kilometers (.75 mile) to go before reaching the base of the"Columbia
Hills," and will reach them by sol 160. Later in the martian day, after
completing the sol 124 drive, Spirit took a 360-degree afternoon
panorama of its surroundings with the navigation camera.
On sol 125, Spirit continued driving and set a new one-sol driving
record of 123.7 meters (405.8 feet). Science on Sol 125 included morning
atmospheric sky and ground remote sensing, mini thermal emission
spectrometer observation of the sol 126 instrument deployment device
work volume, imaging with the panoramic camera, and cloud observations.
After the long sol 125 drive, Spirit was in perfect position to work
with the instrument deployment device on sol 126. This included alpha
particle X-ray spectrometer, Mössbauer and microscopic imager work on a
target called "Lead Foot" (in honor of the big drive on sol 125). The
Mössbauer was used as the feeler for all these activities but touched
down on rocks rather than soil at the "Lead Foot" location, compromising
the Mössbauer and microscopic imager data (images out of focus). Spirit
also did some driving on this sol, and added 55.6 meters (182.4 feet) to
the odometer, bringing Spirit's new drive total to 2,089 meters (1.3
miles). At the end of the sol, Spirit successfully executed a sequence
that used the panoramic camera to find the Sun and correct for
accumulated rover attitude errors.

OPPORTUNITY UPDATE: Crater Cruise - sol 103-106, May 13, 2004
On Sol 103, Opportunity traversed approximately 13 meters (about 43
feet) farther south along the eastern rim of "Endurance Crater,"
reaching the beginning of the "Karatepe" area. On sol 104, the rover
approached "Lion Stone," a rock at the crater's edge that stands about
10 centimeters tall (about 4 inches) and is about 30 centimeters long
(12 inches). This brought Opportunity's total mission odometry to
1,054meters (3,458 feet)!
On Sol 105, Opportunity acquired a series of microscopic images of Lion
Stone and the surrounding soil.
The rover then went on to collect a short Mössbauer integration on the
rock during the day, performed a tool change to the alpha particle X-ray
spectrometer in late afternoon, and acquired that integration in the
early morning of Sol 106. That sol also included additional microscopic
images and a successful "bump" maneuver to reposition the rover so the
top of Lion Stone was in position for the rock abrasion tool on Sol 107.
Remote sensing was also acquired during the two sols, including
panoramic camera images of the heatshield that protected Opportunity
during its toasty trip through the martian atmosphere. The heatshield
impacted approximately 250 meters (about 820 feet) south of Endurance
Crater.
Plans for Sol 107 are to perform a rock abrasion tool grind on Lion
Stone with subsequent microscopic images and alpha particle X-ray
spectrometer overnight integration. The tentative plan for Sol 108 is to
leave Lion Stone and begin traverse to observation position 2 on the
southeastern rim of Endurance Crater.
