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.
