Curiosity continued to work in good health during the Labor Day weekend. The rover drove 98 feet (30 meters) during the mission's Sol 26, on Sept. 1. The drive included a test of the rover's "visual odometry" capability for using onboard analysis of images to determine the distance it has driven. Sol 26 activities also included an empty-cell test analysis by the Chemistry and Mineralogy (CheMin) instrument.
The Sample Analysis at Mars instrument (SAM) analyzed a sample of Martian atmosphere as an overnight activity from Sol 27 to Sol 28 (Sept. 2 to Sept. 3).
Planned activities for Sol 29 (Sept. 4) include another drive.
Sol 28, in Mars local mean solar time at Gale Crater, ended at 1:58 a.m. Sept. 4, PDT.
