Opportunity Clearing The Dust
Pasadena CA (SPX) Jun 25, 2009 Opportunity has been stationary this week resting the right-front drive actuator. During this time, the rover is conducting a series of robotic arm (IDD) activities. On Sol 1913 (June 11, 2009), the rover collected a set of microscopic imager (MI) sky flats to calibrate the camera images. Opportunity also began a mitigation effort for apparent dust on the elevation mirror of its miniature thermal emission spectrometer (Mini-TES). The mirror shroud will be left open to the environment overnight to allow the wind to clean some of the dust off. On Sol 1915 (June 13, 2009), a Mars seismometry experiment was conducted using the rover's accelerometers. On Sol 1918 (June 16, 2009), Opportunity used the MI to collect images of target "Ios" before placing the alpha particle X-ray spectrometer (APXS) for an overnight integration. As of Sol 1919 (June 17, 2009), Opportunity's solar array energy production is 416 watt-hours. Atmospheric opacity (tau) is 0.466. The dust factor is 0.524, indicating that 52.4 percent of sunlight hitting the solar array penetrates the layer of accumulated dust on the array. Opportunity's total odometry remains at 16,569.05 meters (10.3 miles). Share This Article With Planet Earth

Spirit Undertaking More Soil InvestigationPasadena CA (SPX) Jun 25, 2009 Spirit remains stationary on the west side of Home Plate in the location called "Troy". The rover continues to be busy with an ambitious observation campaign employing both remote sensing and in-situ (contact) science with the robotic arm (instrument deployment device, IDD). The soil disturbed by the rover's embedding has been the subject of extensive science investigation. Five out of the ... read more |
