Opportunity Examines 'Absecon'
Pasadena CA (SPX) Jul 14, 2009 Opportunity has driven to a large expanse of outcrop to conduct in-situ (contact) science. On Sol 1932 (June 30, 2009), the microscopic imager (MI) collected a stack of images, and then the Mossbauer spectrometer (MB) was placed on a surface target called "Absecon" for an overnight integration. On Sol 1933 (July 1, 2009), another MI stack of images was taken, and the MB was placed again on Absecon for a multi-sol integration. On Sol 1938 (July 7, 2009), the rock abrasion tool (RAT) performed a seek-scan procedure on a surface target in preparation for brushing. This first attempt did not succeed, but a RAT seek-scan the following sol was successful. During the week, the right-front drive actuator was rested with some active heating in an attempt to mitigate elevated motor currents seen when driving. The shroud of the miniature thermal emission spectrometer (Mini-TES) is being left open for extended periods to allow the environment to clean putative dust contamination from the elevation mirror. As of Sol 1939 (July 8, 2009), Opportunity's solar array energy production is 429 watt-hours, with an atmospheric opacity (tau) of 0.438 and a dust factor of 0.519. Total odometry remains at 16,712.46 meters (10.38 miles). Share This Article With Planet Earth

Spirit Remains Busy At TroyPasadena CA (SPX) Jul 14, 2009 Spirit remains positioned just west of Home Plate, in the location called "Troy," where the rover has been continuing an ambitious science campaign. The campaign includes extensive observations with the panoramic camera (Pancam) and miniature thermal emission spectrometer (Mini-TES) plus contact science using all the tools on the robotic arm (instrument deployment device, or IDD). ... read more |
