SPIRIT UPDATE: Monitoring Magnets on Mars - sol 92, Apr 07, 2004

Spirit awoke on sol 92, which ended at 7:18 p.m. PST on April 6, 
and completed some early morning panoramic camera sky and ground 
measurements. Spirit also took a look at the capture and filter 
magnets with the panoramic camera prior to taking a short 
mid-morning nap. Upon wake-up around 12:30 p.m. Mars Local Solar 
Time, the rover opened the doors on the alpha particle X-ray 
spectrometer and took 3 images of each magnet. Spirit also placed 
the Mössbauer spectrometer on the capture magnet and began an
integration.

In the afternoon, Spirit completed coordinated observations with 
the thermal emission spectrometer instrument on NASA's Mars Global 
Surveyor orbiter. The observations involved miniature thermal 
emission spectrometer pre-flight, simultaneous, and post-flight 
sky and ground measurements. Spirit also collected a panoramic 
camera opacity observation.

Early on Sol 93, which ends at 7:57 p.m. on April 7, the rover 
will switch the instruments on its instrument deployment device 
from the Mössbauer spectrometer to the alpha particle X-ray 
spectrometer. Sol 93 is the last day for newly planned science 
observations, as Spirit will be getting a flight software update 
during sols 94-98.



OPPORTUNITY UPDATE: Traveling Around the Trough - sol 72, 
Apr 07, 2004

"The Wanderer" by Dion and the Belmonts woke Opportunity on its 
72nd sol, which ended at 7:39 a.m. PST on April 7. The rover 
drove around the sinuous trough in a long dogleg pattern. Remote 
sensing to examine the crevice was conducted on the 50-meter 
(164 feet) drive to its ultimate position for the sol, at the
northeast extreme of "Anatolia."

On sol 73, the rover will perform a trenching operation in the 
soil. During the following sol, the instrument's arm will be 
placed on the trenched area.

The planned flight software upload will begin on Opportunity's 
75th sol.
