Spirit then performed a short drive to a target called “Keel,” on the outcrop called “Jibsheet.”

On sol 481, Spirit was able to begin observing a target called “Reef,” using the microscopic imager and performing a 16-hour integration with the alpha particle X-ray spectrometer.

On sol 482 (May 12), Spirit continued work on Reef with instruments on the robotic arm, and performed a 21-hour integration with the Moessbauer spectrometer.

Spirit’s total odometry as of May 12, 2005, is 4,341.19 meters (2.70 miles).
