NASA Mars Exploration Rover Status Report, October 10, 2018: The dust storm on Mars has effectively ended with atmospheric opacity (tau) over the rover site down to around 1.0 to 1.1, values are typical for storm-free conditions this time of year.
No signal from Opportunity has been heard since Sol 5111 (June 10, 2018). As stated previously, it is expected that Opportunity has experienced a low-power fault, a mission clock fault and an up-loss timer fault. The science team has been listening for the rover over a broad range of times using the Deep Space Network (DSN) Radio Science Receiver since loss of signal.
The team has been commanding “sweep and beeps” throughout their daily DSN pass. They are addressing a possible complexity with certain conditions within the mission clock fault. [More at link]
