NASA's Mars Curiosity Rover, expected to land on the Red planet in three weeks, is NASA's most advanced robotic mission yet.<\/p>\n
When NASA's newest rover, Curiosity, reaches Mars in about three weeks, it will not be the first to set its wheels on the Red Planet, but it will be the largest and most advanced robotic explorer that has ever been sent to our planetary neighbor. <\/p>\n

TheCuriosity rover, also called the Mars Science Laboratory, was launched in late November 2011, and is expected to land on Mars on the night of Aug. 5 PDT (early Aug. 6 EDT). The $2.5 billion rover will touch down at Gale Crater, and is designed to search for clues that Mars could be now, or in the ancient past, a habitable planet for microbial life. <\/p>\n
NASA first set its sights on landing on the Red Planet in the 1970s. The agency achieved its first Mars landing in 1976 with the Viking 1 lander. Since then, the agency has had six spacecraft successfullytouch down on the Martian surface. But with the impending arrival of Curiosity, NASA will showcase the most sophisticated Martian rover yet. <\/p>\n
\"The Curiosity landing is the hardest NASA robotic mission ever attempted in the history ofexploration of Mars, or any of our robot exploration,\" John Grunsfeld, associate administrator for NASA's Science Mission Directorate, said in a news briefing Monday (July 16) at the agency's headquarters in Washington, D.C. <\/p>\n
For starters, the way Curiosity will lower itself to the surface of Mars in less than 20 days is unprecedented. The rover will use a new and complex sky crane system to slow its descent. <\/p>\n
According to Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters, Curiosity's landing \"could arguably be the most important event most significant event in the history of planetary exploration.\" [How Curiosity's Nail-Biting Landing Works (Pictures)] <\/p>\n
Previous Mars rovers, such as the twin Spirit and Opportunity rovers (collectively known as theMars Exploration Rovers), used airbags to cushion their landing. Spirit and Opportunity arrived at the Red Planet about three weeks apart in January 2004. Each rover weighs about 384 pounds (174 kilograms), but since Curiosity tips the scales at 1 ton, it was deemed too heavy and too large for an airbag-assisted landing. <\/p>\n<\/p>\n
