Opportunity Lost?

As covered in this blog, NASA is now concerned that the dust storm evolving on Mars over the past few weeks might end the rover missions. The storm has intensified over the latest few days, now covering virtually the entire planet and cutting off as much as 99% of the sunlight. Without sunlight reaching the surface the rovers cannot recharge their power supplies, and will eventually cease to function. Already, NASA has cut far back on rover activities in an attempt to preserve them until the storm blows itself out.
