Mars Rover, Curiosity Rover | featured news

The rover Curiosity, nearing Mars, has sophisticated tools to help answer the question: Did the Red Planet ever sustain life — and could it today? In a matter of days, a geologist unlike any on Earth will venture into alien territory.

The one-ton, car-sized Curiosity rocketed from Kennedy Space Center Saturday. The vehicle is on a two-year mission to determine whether life could have existed on Mars.

As big as a car and as well-equipped as a laboratory, NASA's newest Mars rover blows away its predecessors in size and skill. Nicknamed Curiosity and scheduled for launch on Saturday, 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. "This is a Mars scientist's dream machine," said NASA Jet Propulsion Laboratory's Ashwin Vasavada, the deputy project scientist. Once on the red planet, Curiosity will be on the lookout for organic, carbon-containing compounds. While the rover can't actually detect the presence of living organisms, scientists hope to learn from the $2.5 billion, nuclear-powered mission whether Mars has - or ever had - what it takes to nurture microbial life.
