Computer Modeling Supplements Dusty Testing![]() Tests on Earth simulating Spirit's predicament on Mars have reinforced understanding that getting Spirit to rove again will be very difficult. To supplement the tests at NASA's Jet Propulsion Laboratory in Pasadena, Calif., the rover team is refining a detailed computer model of rover mobility, calibrated with results from testing and measurements from Mars. "The computer modeling ... more Spirit Update: Examining Target 'Olive Leaf' ![]() Spirit is continuing remote sensing and in situ science while positioned at her embedded location on the west side of Home Plate. On Sol 2015 (Sept. 3, 2009), a Moessbauer (MB) integration was completed on target "Olive Leaf." On the next sol, a rock abrasion tool (RAT) calibration and a RAT diagnostics were performed, then the APXS was placed on Olive Leaf for an overnight integration. ... more Opportunity Update: Circling The Meteorite ![]() Opportunity has commenced circumnavigation and full-circle imaging of the large meteorite "Block Island". On Sol 1997 (Sept. 5, 2009), the rover moved 5.7 meters (18.7 feet) to the second of six stand-off positions around the meteorite (the first position being the initial rover location). At each location Opportunity collects a set of images with the panoramic camera (Pancam). ... more |

Opportunity Continues Meteorite Examination - Sol 1981-1987![]() Opportunity is continuing its contact investigation of the 70-centimeter (28-inch) meteorite called "Block Island." On Sol 1981 (Aug. 20, 2009), the rover performed a very small rotation that moved the robotic arm (instrument deployment device, or IDD) in azimuth to reach new targets on the meteorite. On the next sol, the IDD collected a stack of microscopic imager (MI) images of ... more Mars Orbiter Puts Itself In Safe Mode Again ![]() NASA's Mars Reconnaissance Orbiter put itself into a safe mode Wednesday morning, Aug. 26, for the fourth time this year, while maintaining spacecraft health and communications. While in safe mode, the spacecraft has limited activities pending further instructions from ground controllers. Engineers have begun the process of diagnosing the problem prior to restoring the orbiter to normal ... more NSF Awards Space@VT Grant To Improve Space Weather Understanding ![]() Members of Virginia Tech's Space@VT research group are receiving a $2 million grant from the National Science Foundation (NSF) to build a chain of space weather instrument stations in Antarctica. Space weather affects a variety of everyday consumer technologies including global positioning systems (GPS), satellites for television reception, and cellular phones. Also, the understanding of space ... more |
