Spirit Status at end of sol 58

On sol 58, which ends at 7:52 p.m., PST on March 2, the planned four-hour rock abrasion tool grind of "Humphrey" was limited to only 20 minutes. The intricate slopes and cracks of the rock make it a challenging target for instruments. When sensors indicated a loss of contact with surface material, the software perceived a problem and the rock abrasion tool was moved away from the rock. Engineers are amending the software limits to duplicate the rock abrasion tool's earlier operation on the rock "Adirondack," giving a higher likelihood of successful completion on the next sol.

The morning began with the completion of the alpha particle X-ray spectrometer integration on the previously brushed area. The panoramic camera then took a multi-spectral observation of the nearby ground, followed by a Moessbauer spectrometer integration on the same area.

Spirit's Sol 58 wake-up song was "I Still Haven't Found What I'm Looking For" by U2 to pay homage to its twin rover's amazing findings of water evidence at Meridiani Planum.

On sol 59, Spirit will attempt another rock abrasion tool grind on "Humphrey," followed by detailed observations of the hole.
