I wonder just how high the dust extends into the atmosphere during the dust storms.
Not sure, but I did read that the earlier Opportunity rover operated on Mars for 16 years(!!) finally gave up the ghost after being engulfed in a severe dust storm which likely covered its solar panels in a heavy coat of dust.
16 years and no oil changes or service! Amazing
