Daily Updates - May 27, 2005
Opportunity Status at end of sol 469-475

Opportunity continues to make slow progress through the sand dune, at a slip rate of roughly 99.5 percent. From the time Opportunity resumed driving after digging into the dune until May 26, drives totaling 64.8 meters (about 213 feet) of wheel rotations have been commanded and executed, producing 34.8 centimeters (1.1 feet) of forward progress.

Opportunity has also been performing atmospheric observations. Each sol the rover takes two measurements of how clear the sky is, checks for clouds, and does a Sun survey. A few sols ago a daily horizon survey was added, and Opportunity also imaged its magnets with the panoramic camera.

Sol-by-sol summaries:
Sol 469 (ending on May 20):
Two meters (6.6 feet) of commanded motion, resulting in 1.1 centimeters (0.4 inch) of progress.

Sol 470:
Twelve meters (39 feet) of commanded motion; about 6 centimeters (2.4 inches) of progress.

Sol 471:
Twelve meters (39 feet) of commanded motion; about 6 centimeters (2.4 inches) of progress.

Sol 472:
Twelve meters (39 feet) of motions was commanded. Only the first 2 meters were executed. After that step, the rover stopped the drive by itself due to uncertainty about its own position. One centimeter (0.4 inch) of progress was made.

Sol 473:
Planning was suspended today due to issues with the ground data system. The rover executed a pre-loaded science sequence.

Sol 474:
Eight-meter (26-foot) drive planned, yielding 3.7 centimeter (1.5 inches) of progress.

Sol 475 (ending on May 26, 2005):
Ten-meter (33-foot) drive planned; 8.8 meters (29 feet) executed; 3.5 centimeters (1.4 inches) of progress

Looking ahead:
Thursday, May 26, the team planned two sols (476 and 477), and Friday, May 27, the team is planning three sols to cover the holiday weekend. Sol 476 will command 12 meters (39 feet), and every other sol will require a "go/no-go" decision that will allow for 0 meters, 2 meters (7 feet), or 12 meters (39 feet) of commanded motion per sol.
