After a slightly slippery start yestersol, Opportunity made it out of "Eagle Crater" on sol 57, which ends at 8:45 p.m. PST on March 22. The drive along the crater's inner slope that was initiated on the last sol continued this sol until Opportunity exited its landing-site crater. Images from the navigation camera confirm that the rover is about 9 meters (about 29.5 feet) outside of the crater. The rover also conducted remote sensing observations between naps this sol. After completing the drive out of the crater, the navigation camera imaged Opportunity's brand new view of the plains of Meridiani Planum. During the martian night, rover planners will awaken Opportunity to take miniature thermal emission spectrometer observations of the ground and the atmosphere. The song chosen to motivate Opportunity to move up and out of the crater was "If You Don't Get it the First Time, Back Up and Try it Again" by the JBs and Fred Wesley.
Spirit Update After waking, Spirit warmed-up the mast actuators for some early morning soil and atmosphere miniature thermal emission spectrometer observations. It then went back to sleep before beginning the morning direct-to-earth communication session with the high gain antenna. At 10:00 a.m. Mars Local Solar time, Spirit began analyzing the soil targets "Saber" and "Sandbox" with the mini thermal emission spectrometer. It also took panoramic camera images of "Skull" and Saber. Then it was time to unfold the instrument arm to capture microscopic imager images of three targets on Mazatzal: "Arizona," "Illinois," and "New York." The New York target was further analyzed with a 17-hour Moessbauer spectrometer integration. While the Moessbauer was integrating, Spirit proceeded to execute several mini thermal emission spectrometer and panoramic camera observations of interesting features in the surrounding area. The observations included images of "Bonneville" crater, "Saber," "Sandbox" and "Orange Beach." Spirit had completed all these activities by 2:40 p.m. Mars Local Solar time and then took a siesta until the afternoon Odyssey UHF pass. During that pass, the rover captured mini thermal emission spectrometer ground and sky images. Before shutting down at 5 p.m. Mars Local Solar time, Spirit positioned the panoramic camera for a nighttime observation of the moon Deimos. Sol 79, which ends at 9:43 a.m. on March 24, 2004, will be a momentous day for Spirit's rock abrasion tool; it will complete brushings on two Mazatzal targets.

Mars Rover Opportunity Slips On First Crater Exit Attempt
Pasadena - Mar 22, 2004NASA's Opportunity tried driving uphill out of its landing-site crater during its 56th sol, ending at 10:05 p.m. March 21, PST, but slippage prevented success. The rover is healthy, and it later completed a turn to the right and a short drive along the crater's inner slope. Controllers plan to send it on a different route for exiting the crater on sol 57. |
