Spirit Status at end of sol 99

Spirit began Sol 99, which ended at 11:55 p.m. PDT on April 13, 2004, by doing a systematic ground survey with the miniature thermal emission spectrometer. After that, the rover completed a six-position brush mosaic on the rock "Route 66" with the rock abrasion tool. Once the brushing was complete, Spirit analyzed the area with the microscopic imager and Moessbauer spectrometer.

The afternoon science for the sol included imaging of rocks called "Back Lot" and "Cameo" with the panoramic camera and the miniature thermal emission spectrometer. Spirit took a short nap and woke up for the afternoon Odyssey pass.

During the martian night, Spirit changed from using the Moessbauer spectrometer to using the alpha particle X-ray spectrometer.

Sol 100, which will end at 12:35 a.m. PDT, April 15, 2004, will be a sol full of roving as Spirit continues toward the "Columbia Hills."
