Spirit Completes Fourth Mile On Mars

Spirit is healthy and continues to make progress toward "Home Plate" after driving more than 150 meters (492 feet), taking images, making atmospheric observations, and analyzing geology.

Spirit completed two diagnostic tests of the dynamic brakes on sol 735 (Jan. 27, 2006) after the team detected a dynamic brake fault associated with the left-front and right-rear steering actuators on Sol 733. The tests were copies of tests that were run after a similar anomaly on sol 265 for Spirit.

Also on sol 735, the rover performed a small wheel wiggle after its drive to test the dynamic brakes. The wheel wiggle steered the wheels slightly, then steered them straight. No dynamic brake warnings were observed.

The intermittent behavior of the relay status that controls the dynamic brakes, as well as the results of the diagnostic activities, are consistent with the behavior observed after the sol 265 anomaly. The team continued with the same resolution, which was to instruct the rover to ignore the dynamic brake error status. Driving has continued with normal steering function.
