Mars' skies are clearing up, but the Opportunity rover is still fast asleep
For the past three months, Mars has been in the midst of a global dust storm, depriving the red planet almost entirely of sunlight. That's been particularly challenging for the heavenly body's resident robot, the solar-powered Opportunity rover, and his commanding engineers back here on Earth. But this week, the skies have become much clearer, with the Sun's light finally reaching the planet's surface. Unfortunately, it seems the skies are still not bright enough for the rover to wake.
