The global dust storm on Mars has ended and atmospheric opacity (tau) over the rover site hovers around a typical seasonal value between 1.0 and 1.2. No signal from Opportunity has been heard since Sol 5111 (June 10, 2018). Opportunity likely experienced a low-power fault, a mission clock fault and an up-loss timer fault. The team has been listening for the rover over a broad range of times and frequencies using the Deep Space Network (DSN) Radio Science Receiver. They have been commanding "sweep and beeps" throughout the daily DSN pass with both right-hand, and now left-hand circular polarization to address a possible complexity with certain conditions within mission clock fault. Total odometry is unchanged at 28.06 miles (45.16 kilometers).
NASA will keep trying to contact stalled Mars rover Opportunity Washington (AFP) Oct 30, 2018 NASA has changed its mind about how long it will continue to seek contact with an aging robotic vehicle that was blanketed in a dust storm on Mars back in June and has been stalled ever since. Now, the space agency plans to keep trying, rather than abandon efforts some time this month, as officials had said in late August. "After a review of the progress of the listening campaign, NASA will continue its current strategy for attempting to make contact with the Opportunity rover for the foreseeab ... read more
