Opportunity Status at end of sol 22

Opportunity spent much of sol 22, which ended at 9:39 p.m. Sunday, PST, making a thorough "before" examination of the spot selected for digging a ditch the next sol.

Also, Opportunity completed upward-looking observations before, during and after Mars Global Surveyor flew overhead looking down. Opportunity and Global Surveyor have similar infrared sensing instruments: the miniature thermal emission spectrometer on the rover and the (full-size) thermal emission spectrometer on the orbiter. Coordinated observations of looking up through the atmosphere with one while looking down through the atmosphere with the other were designed to provide a more complete atmospheric profile than either could do alone.

Sol 22's wake-up music was "Invisible Touch" by Genesis. In preparation for digging, Opportunity examined the trenching site with its microscopic imager, its Moessbauer spectrometer and, overnight, its alpha particle X-ray spectrometer.

The plan for sol 23, which will end at 10:19 p.m. Monday, PST, is to dig a trench with alternating forward and backward spinning of Opportunity's right front wheel in order to see what's below the surface. Inspections of the resulting hole are planned for sol 24 and the morning of sol 25.
