On Aug. 5, as nervous JPL engineers watch, the fate of the rover — capable of pulverizing rocks and ingesting soil — will rest on a landing sequence so far-fetched that some scientists were skeptical it could work.

Firing on all engines, NASA's latest rover to Mars executed a course adjustment Wednesday that put it on track for a landing in August.

As big as a car and as well-equipped as a laboratory, NASA's newest Mars rover blows away its predecessors in size and skill. Nicknamed Curiosity and scheduled for launch on Saturday, the rover has a 7-foot arm tipped with a jackhammer and a laser to break through the Martian red rock. What really makes it stand out: It can analyze rocks and soil with unprecedented accuracy. "This is a Mars scientist's dream machine," said NASA Jet Propulsion Laboratory's Ashwin Vasavada, the deputy project scientist. Once on the red planet, Curiosity will be on the lookout for organic, carbon-containing compounds. While the rover can't actually detect the presence of living organisms, scientists hope to learn from the $2.5 billion, nuclear-powered mission whether Mars has - or ever had - what it takes to nurture microbial life.

The first rock a NASA rover looked at when it arrived at a crater on Mars was unlike any looked at on the planet before, scientists said... And the first rock it looked at has already opened a new chapter in the study of Mars, NASA scientists said Thursday. On a telephone news conference, mission scientists giddily described that rock: full of zinc and bromine, elements that, at least for rocks on Earth, would be suggestive of geology formed with heat and water.

NASA's surviving Mars rover Opportunity has reached the rim of a 14-mile-wide crater where the robot geologist will examine rocks older than any it has seen in its seven years on the surface of the red planet, scientists said Wednesday....

NASA's Dawn spacecraft on Saturday became the first probe ever to enter orbit around an object in the main asteroid belt between Mars and Jupiter.

NASA's next-generation rover mission to the surface of Mars needs more money – again. Nine months before the scheduled launch, the space agency says the mission has burned through its reserves and needs another $82 million to complete testing before liftoff.

Thirty-four years after NASA's Viking missions to Mars sent back results interpreted to mean there was no organic material - and consequently no life - on the planet, new research has concluded that organic material was found after all.

If NASA's exploration of Mars were summed up in a bumper sticker, it would read: "Follow the water."...

NASA is considering a plan to get around limited budgets set in Washington by stretching out missions to bring back samples from Mars, a researcher said on Wednesday.
