Things are not looking good for the stricken rover which stopped communicating following a dust storm in June.
It is looking increasingly likely that the recent Martian dust storm may have silenced the rover for good.
The dust storm that left the Opportunity rover out of commission is now classed as 'planet-encircling'.
The long-lived rover has halted its science work while it waits out a massive dust storm on Mars.
A growing dust storm on the Red Planet could pose a risk to NASA's two active Mars rovers.
