 by Staff Writers Pasadena CA (JPL) Nov 14, 2018
The global dust storm on Mars has ended and atmospheric opacity (tau) over the rover site has dropped to a storm-free level of 0.8. Since loss of signal on Sol 5111 (June 10, 2018), 253 recovery commands have been radiated. No signal from Opportunity has been heard. 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, frequencies and polarizations 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 left-hand circular polarization, to address a possible complexity with certain conditions within the mission clock fault. Total odometry is unchanged at 28.06 miles (45.16 kilometers).
Five Months Since We Received A Signal From Opportunity Pasadena CA (JPL) Nov 08, 2018 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.
