    Mars Curiosity Rover Is NASA's Biggest, Most Advanced Space-Exploration Robot Ever


    Mars Curiosity Rover Is NASA's Biggest, Most Advanced Space-Exploration Robot Ever

    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.
    The Curiosity 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.
    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 successfully touch down on the Martian surface. But with the impending arrival of Curiosity, NASA will showcase the most sophisticated Martian rover yet.
    "The Curiosity landing is the hardest NASA robotic mission ever attempted in the history of exploration 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.
    Bigger and better
    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.

    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)]
    Previous Mars rovers, such as the twin Spirit and Opportunity rovers (collectively known as the Mars 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.
    "The mass of Spirit and Opportunity was just about at the limit for what that airbag design could handle," McCuistion said.
    Spirit and Opportunity were designed for three-month missions on Mars, but both far outlived their warranties. After getting stuck in Martian sand and losing contact with Earth, Spirit was officially declared dead in May 2011. But, Opportunity is still alive and well, and is currently exploring a massive crater, called Endeavour. Since it landed on the Red Planet, Opportunity has logged an impressive 21.4 miles (34.4 km).
    Like its two predecessors, Curiosity will be equipped with six wheels with individual driver motors and a suspension system to help it drive up inclines and combat the difficult Martian terrain. But Curiosity will also be able to move faster, with 3.35 miles per hour (5.39 kilometers per hour) being its top speed on flat, hard ground. For comparison, Opportunity's maximum speed is approximately 0.1 miles per hour.
    "Mars Science Lab [is the] most challenging mission we've ever sent to another planet, and certainly the most challenging we've sent to Mars," McCuistion said. "It truly is a major step forward both in technology and in potential science return and science capability, to unlock the mysteries of Mars in places that have never been accessible to humankind in the past." [7 Biggest Mysteries of Mars]
    A new suite of instruments
    Curiosity is designed to perform detailed analyses of Martian rocks and soil, including what lies beneath the surface. The rover is equipped with 10 different instruments that have a collective mass of 165 pounds (75 kilograms). Spirit and Opportunity each carried five instruments, totaling 11 pounds (5 kg).
    Curiosity will be able to dig, snap high-definition pictures of Mars, analyze chemical properties of soil and rock samples, study minerals, and even blast rocks with a laser to measure their chemical compositions.
    As one of the key indicators of potential habitability, Curiosity will investigate thepresence of water around Gale Crater.
    "Over the last decade-and-a-half of exploration, we have found more water than expected," said Michael Meyer, lead scientist for NASA's Mars Program at NASA headquarters. "With the landing of Curiosity, the adventure begins as we explore the past and present of Gale Crater."
    As NASA prepares for Curiosity's nail-biting trip through the atmosphere of Mars, mission managers anticipate the huge rover will herald a new age of exploration on the Red Planet and beyond.
    "The Mars Exploration Program was designed to create steady progress in both technology and scientific capabilities at other planets," McCuistion said. "NASA was created to take on big challenges, and that's what this one is. MSL is forging ahead in greater and greater ways for science and for technology. Robert Kennedy said, 'Only those who dare to fail greatly can ever achieve greatly.' MSL is poised to do great things."

    I think its just a matter of time til they find concrete evidence of at least microbial life. I hope they send a rover to investigate that underground cavern with the 35 meter opening on top.

    Here is a great video about the reality of landing Curiosity on the surface of Mars...

    My stepson built and tested some of the solar panels being Curiosity prior to landing, or right about now. They're providing power till the landing phase which is where the video starts, then they break away before entry into the atmosphere.

    He thinks it's cool to have some small connection to this mission. So do I.

    Thank you for providing all the info. so that we could see it live! It's a great way to start the day.
    I was sort of hopeing to see two little green men to appear in a 1949 replica 2 door Mercury to pull up and check it out.
    Maybe next time!!

    Don't worry Gman, Curiosity will get a picture of that for you, but it will be attributed to a faulty lens, Mars dust and a rear reflector.
    Long ACTC since Nov. 2008 FTW!
