SPIRIT UPDATE: Roving Toward the Rim - sol 65, Mar 10, 2004
Spirit spent sol 65, which ended at 12:29 a.m. PST on March 10, analyzing soil targets with the alpha particle x-ray spectrometer, Moessbauer spectrometer and microscopic imager before stowing its arm, doing some remote sensing of the trench dubbed "Serendipity Trench," and then finally setting off for the longest directed drive to date. That drive was 27 meters (88.6 feet) toward the edge of "Bonneville" crater.
Spirit then attempted to use auto navigation to reach a target that was an additional 6 meters (19.7 feet) away. Sensitive obstacle avoidance software prevented Spirit from reaching the destination, and like yestersol, the rover completed several drives forward and back. Those drives resulted in a final odometer reading of 40.7 meters (133.5 feet) for the day, even though the total straight-line distance traveled was 30 meters (98.4 feet).
The 30-meter (98.4 feet) drive put Spirit close enough to "Bonneville's" edge to take images with the navigation cameras that reveal the opposite rim of the crater.
On sol 66, which ends at 1:09 a.m. PST on March 11, 2004, Spirit will drive up to the summit of the rim and show us what's inside with a 180-degree navigation camera panorama.
OPPORTUNITY UPDATE: Halfway Mark - sol 45, Mar 10, 2004
On sol 45, which ended at 12:50 p.m. PST on Wednesday, March 10, Opportunity awoke to ''Eclipse" by Pink Floyd in recognition of the transit of the martian moon, Phobos. A second song, "Meet Me Halfway" by Kenny Loggins, was played because Opportunity is halfway through its primary 90-sol surface mission.
Opportunity used the rock abrasion tool brush to sweep off the dirt in and around the hole at "Mojo 2" in the "Flat Rock" area. Opportunity then took five microscopic images of the freshly brushed "Mojo 2."
The miniature thermal emission spectrometer took measurements at three locations on the surface of Mars, and then pointed upwards to observe the atmosphere in four different directions. The panoramic camera was also busy taking images of the magnets around the rock abrasion tool area, "Mojo 2" post brushing, and a new area called "Slick Rock."
The plan for sol 46, which will end at 1:30 p.m. PST on Thursday, March 11, is to use the science instruments on the end of the robotic arm on the area dubbed "Berry Bowl."
