Sol 335 Update On Curiosity From USGS Scientist Ken Herkenhoff: Limited Visibilty

15 July 2013

The first few drives toward Mt. Sharp have been limited in length because some of the mobility software has not yet been checked out on the B computer. There are separate Hazcam and Navcam stereo pairs connected to each side of the computer, and the B Navcams behave a bit differently than the A Navcams. The camera pointing changes slightly with temperature, and had to be measured by taking images at various times of day. An improved model for the B Navcams has been loaded onto the rover, so now the software can be tested. Similar tests were required on the A computer early in the mission. In the meantime, drives have been limited to about 40 meters or less, depending on how much terrain is visible in the Navcam images from each location.
