Sol 311 Update On Curiosity From USGS Scientist Ken Herkenhoff: The Approach25 June 2013
MSL continues to study the "Shaler" outcrop, slowed a bit by minor driving problems. Last week, the tilt of the rover exceeded the 12-degree limit during a drive toward the center of the outcrop, so the drive had to be commanded again. That drive was successful except that it ended with the left middle wheel about 20 cm higher than expected on a rock. This situation is not dangerous, but concerns about slipping off the rock while using the arm have precluded use of the arm at this location. Fortunately, it is still possible to acquire remote sensing data, including lots of Mastcam stereo observations and ChemCam measurements.
