Daily Updates - July 27, 2004
Opportunity Status at end of sol 174-176

On sol 174, Opportunity completed close-up examination of a rock target called "Arnold Ziffel" using the rover's microscopic imager, Moessbauer spectrometer and alpha particle X-ray spectrometer. All observations were successful.

Leaving Arnold Ziffel on sol 175, Opportunity backed up to capture an image the results of the close-up work, and then moved on down slope to a new target. This move will leave the rover about 13 meters (about 43 feet) down from the lip of the crater. The rover was put into deep-sleep, energy-saving status overnight from sol 175 to sol 176.

Sol 176, ending on July 23, was a driving day. Opportunity moved down the slope (and east) to a position to investigate a target called "Diamond Jenness." Everything executed as planned, leaving the rover in a great position to grind into the target with its rock abrasion tool.

The engineering team is looking into a concern about the driving surface. The downslope pavement requires close examination before the rover traverses, to ensure the sand covering the pavement is still capable of supporting Opportunity. Recent experience has shown up to 30 percent slip.
