NASA’s Mars Curiosity Rover

Posted on June 16, 2011  Comments (8)

Curiosity is the name of the new rover from NASA. It will be launched to continue the exploration of Mars so successfully done by Spirit and Opportunity (2 previous Mars rovers that did some amazing work and laster years longer than expected). The rover is NASA’s Mars Science Laboratory, a mobile robot for investigating Mars’ past or present ability to sustain microbial life.

Once on the surface, the rover will be able to roll over obstacles up to 75 centimeters (29 inches) high and travel up to 90 meters per hour. On average, the rover is expected to travel about 30 meters per hour, based on power levels, slippage, steepness of the terrain, visibility, and other variables.

The rover is about the size of a small SUV — 10 feet long (not including the arm), 9 feet wide and 7 feet tall. It weighs 900 kilograms (2,000 pounds)

The rover will carry a radioisotope power system that generates electricity from the heat of plutonium’s radioactive decay. This power source gives the mission an operating lifespan on Mars’ surface of a full martian year (687 Earth days) or more, while also providing significantly greater mobility and operational flexibility, enhanced science payload capability, and exploration of a much larger range of latitudes and altitudes than was possible on previous missions to Mars.

    Ok, now this sounds ironic to me… I mean one must say the continuous height of success of NASA in the mars exploration and if there is life then wht kind of people has already been living their and more other information which is really valuable to us…

    NASA being the mark of excellence producing great opportunities to live a better and more advanced life technically!

    Truly Awesome!

    Go Curiosity! 🙂
    May be worth mentioning that the mission is scheduled to launch between Nov. 25 and Dec. 18, 2011 and arrive on Mars sometime in August 2012

    Its quite good to see that after successful missions of “Spirit and Opportunity” the NASA has developed another vehicle to continue MARS mission and the most impressive thing to me is that it would a unique power system which will going to run a full martian year. I hope that scientist will develop something like ” plutonium’s radioactive decay” for generating power electricity on commercial scale. Thanks for sharing this news with us and please do share more on this in future.

    Great vehicle! I hope Curiosity will find something really interesting on the Red planet.

    I had the opportunity to see the real and mockup of the Mars rover last June. You can see the pix here:

    Sadly, today is the first day that I cannot drive my Prius in the carpool lane alone. How will I ever get from my LAX-area office to JPL in Pasadena on time for meetings?

    This attempt failed also, making Russia 0 for 17 on Mars attempts. In the last few years Russia has shown a renewed interest in investing in space exploration…
