Mars atmospheric opacity (tau) over the rover site is estimated to be somewhere in the range of 0.9 to 1.3. No signal from Opportunity has been heard since Sol 5111 (June 10, 2018) during the historic global dust storm. Opportunity likely experienced a low-power fault, a mission clock fault and an up-loss timer fault. The team is continuing to listen for the rover over a broad range of times, frequencies and polarizations using the Deep Space Network (DSN) Radio Science Receiver. The team has begun mission clock fault recovery commanding "in the blind," in the hopes of catching the rover during an awake period, as their strategy of last resort. Since loss of signal, over 835 recovery commands have been radiated to the rover. Total odometry is unchanged at 28.06 miles (45.16 kilometers).
NASA's Opportunity Rover Logs 15 Years on Mars Pasadena CA (JPL) Jan 25, 2019 NASA's Opportunity rover begins its 16th year on the surface of Mars today. The rover landed in a region of the Red Planet called Meridiani Planum on Jan. 24, 2004, sending its first signal back to Earth from the surface at 9:05 p.m. PST (Jan. 25, 2004, at 12:05 a.m. EST). The golf-cart-sized rover was designed to travel 1,100 yards (1,006 meters) and operate on the Red Planet for 90 Martian days (sols). It has traveled over 28 miles (45 kilometers) and logged its 5,000th Martian day (or sol) back in Fe ... read more
