NASA rover Curiosity lands on Mars

NASA rover Curiosity lands on MarsThe Mars science rover Curiosity landed on the Martian surface shortly after 10:30 p.m. Pacific time on Sunday (1:30 a.m. EDT Monday/0530 GMT) to begin a two-year mission seeking evidence the Red Planet once hosted ingredients for life, NASA said. Mission controllers at the Jet Propulsion Laboratory near Los Angeles said they received signals relayed by a Martian orbiter confirming that the rover had survived a make-or-break descent and landing attempt to touch down as planned inside a vast impact crater. NASA has described the feat as perhaps the most complex ever in robotic spaceflight.The $2.5 billion Curiosity project, formally called the Mars Science Laboratory, is NASA's first astrobiology mission since the 1970s-era Viking probes. The landing, a major victory for a U.S. space agency beleaguered by budget cuts and the recent loss of its space shuttle program, was greeted with raucous applause and tears of joy by jubilant engineers and scientists at mission control.(Reuters)  Nicknamed Curiosity and scheduled for launch, 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.  In this image from NASA TV, shot off a video screen, one of the first images from the Curiosity rover is pictured of its wheel after it successfully landed on Mars.

NASA released the image just minutes after the rover's successful Aug. 5 PDT, 2012 landing.

Curiosity will land near the Martian equator about 10:31 p.m., on August 5, 2012 in the late evening  This artist's concept depicts the rover Curiosity, of NASA's Mars Science Laboratory mission, as it uses its Chemistry and Camera (ChemCam) instrument to investigate the composition of a rock surface. REUTERS/ NASA/JPL-Caltech/Handout  Ten feet long, 9 feet wide and 7 feet tall at its mast, Curiosity is about twice the size of previous rovers Spirit and Opportunity, weighs 1 ton and is loaded with 10 science instruments. Its formal name: Mars Science Laboratory, or MSL.  An engineering model of NASA's Curiosity Mars rover is seen from the rear in a sandy, Mars-like environment named the Mars Yard at NASA's Jet Propulsion Laboratory in Pasadena, California July 25, 2012. The real Curiosity rover, part of the Mars Science Laboratory mission, is on its way to the Red Planet, with a planned arrival and landing on the evening of August 5 PDT, early morning August 6 EDT.

REUTERS/Fred Prouser (UNITED STATES - Tags: SCIENCE TECHNOLOGY)  The rover is scheduled to arrive at the mineral-rich Gale Crater next August, 8½ months after embarking on the 354-million-mile voyage aboard an Atlas V rocket.  The rover also has a weather station for updates on Martian temperature, humidity and wind, as well as a radiation detector that will be especially useful for planning human expeditions.  Despite all its fancy upgrades, Curiosity will go no faster than the one-tenth-mile-per-hour logged by past Martian rovers. But it is expected to venture more than 12 miles during its two-year mission. If it's still working after that, it will keep on trucking, possibly all the way up the crater's 3-mile peak.
