Observers Anxious for Dust to Settle as Mars Opposition Approaches
With opposition only weeks away, will the current global dust storm finally break? We look at the prospects.
What Are Curiosity and Opportunity Up To?
As Schiaparelli prepares to land on Mars, how are the other robotic denizens of the Red Planet doing?
Opportunity Rover Gets a Cleaning
The Mars rover Opportunity has been cleaned of heavy dust coating its solar panels, thanks to some strong winds blowing over the rim of Endeavour Crater.
Opportunity's 10-year Martian Marathon
Can you believe it? A robotic rover designed to last 90 days on the Red Planet is celebrating 10 years of successful exploration on the Red Planet — even taking a "selfie" for its handlers back on Earth.
Opportunity Takes a Bow, Gets Some Rest
It's been eight years since NASA dropped twin rovers onto the Martian surface. Spirit succumbed to the planet's harsh conditions in 2010, but Opportunity continues to amaze mission scientists with its longevity and scientific productivity.
Opportunity Reaches Its New Home
The surviving one of NASA's two Mars Exploration Rovers is reaching the brink of a whole new adventure on Mars.
Opportunity's Mad Dash
After spending 4½ years doing geologists' bidding on Mars, you'd think that NASA would give its rovers a rest. Instead, one of them has started rolling toward a large crater that it likely won't reach for two years.
Opportunity is Going In
Now that the dust storms have passed, the Mars Exploration Rover Opportunity should begin studies inside Victoria Crater in the coming weeks.
