This handout image provided by NASA, taken Sept. 28, 2012, is a mosaic of images taken by the telephoto right-eye camera of the Mast Camera before the rover arrived at Rocknest. Mars Curiosity is about to sip its initial taste of the red planet's sand. But first, NASA's rover has to play bartender to make sure the dry dust is shaken, not stirred.The rover's scoop will dig into the sand Saturday. Then the action starts. Mission sampling chief Daniel Limonadi said the end of the rover's arm will shake vigorously and noisily for eight hours, like a Martian martini mixer gone mad. That will vibrate the fine dust grains through the rover chemical testing system to cleanse it of unwanted residual Earth grease. (AP Photo/NASA)

This pair of images provided by NASA/JPL-Caltech from the Mast Camera on NASA's Curiosity rover shows the upper portion of a wind-blown deposit dubbed "Rocknest." The rover team recently commanded Curiosity to take a scoop of soil from a region located out of frame, below this view. The soil was then analyzed with the Chemistry and Mineralogy instrument, or CheMin. The colors in the image at left are unmodified, showing the scene as it would appear on Mars, which has a dusty red-colored atmosphere. The image at right has been white-balanced to show what the same area would look like under the lighting conditions on Earth. The rounded rock located at the upper center portion of the images is about 8 inches (0.2 meters) across. (AP Photo/NASA/JPL-Caltech/MSSS via The Herald-Times)

Mars rover Curiosity set to hit the road again

LOS ANGELES - After playing in the sand, the Curiosity rover is poised to trek across the Martian landscape in search of a rock to drill into, scientists reported Thursday.
The six-wheel rover has been parked for more than a month at a sand dune where it has been busy scooping up soil, sniffing the atmosphere and measuring radiation levels on the surface. Its next task is to zero in on a rock and that requires driving to a new location.
Mission deputy scientist Ashwin Vasavada expected Curiosity to be on the move in the "next few days."
"It's the bedrock which really gives you the story of ancient Mars," said Vasavada of the NASA Jet Propulsion Laboratory, which manages the $2.5 billion mission. "The soil is a little harder to interpret because we don't know how old it is or where it came from."
The car-size rover touched down in Gale Crater, an ancient depression near the Martian equator, in August on a two-year mission to probe whether the landing site once had conditions capable of supporting microbial life. Armed with a high-tech suite of instruments, it's the most sophisticated spacecraft to ever land on the red planet.
During the first three months, a weather station aboard Curiosity detected brief drops in air pressure, a sign of whirlwinds in the region.
"These events are starting to occur more and more often," said Manuel de la Torre Juarez of NASA JPL. "We expect to see more in the future."
Previous rovers have spotted and even recorded dust devils dancing across the Martian terrain, but scientists said Curiosity has not yet seen evidence that the swirling winds have lifted dust.
Curiosity's ultimate destination is a 3-mile-high mountain rising from the center of the crater floor that's rich in mineral deposits. Scientists had hoped to drive to the base of the mountain before the end of the year, but that doesn't look likely after the extended stay at its current spot.
