Opportunity Status at end of sol 21
Opportunity completed its longest drive so far -- about 9 meters or 30 feet -- during its 21st sol on Mars, which ended at 9 p.m. Saturday, PST. The rover finished the drive with its first U-turn, arriving at a location selected for the mission's first trenching operation. Plans call for examining the hematite-rich surface of this location, called "Hematite Slope," during sol 22, then spinning one wheel to dig below the surface on sol 23.
Controllers at JPL chose "Send Me on My Way," by Rusted Root, and "Desert Drive," by Tangerine Dream, as Opportunity's wake-up music for sol 21. The rover worked a long day. It awoke earlier than usual for an early morning observation with its panoramic camera. It made additional observations from its new location just before finishing the drive, and again after finishing the last bit of the drive. Then it was woken after dark to make the mission's first nighttime observations with its infrared sensor, the miniature thermal emission spectrometer.
