After a series of moderately successful Mars Exploration Rovers (MER), NASA is about to take its game to the next level. Say hello to Curiosity, which is 10 feet (3m) long and weighs almost a ton, four times more than Spirit and Opportunity. It is expected to launch in November or December, and arrive on Mars about eight months later.
Not only is Curiosity huge, but it’s also equipped with a robot arm, a laser that can vaporize rocks at seven meters, and a percussive drill for boring into Mars’ surface. The machine itself is powered by the heat given off by 4.8kg plutonium dioxide, meaning it won’t rely on solar power, which has caused issues with older space craft. It’s not just the rover itself that’s cool cool, though: because it’s so heavy, Curiosity can’t use the highly scientific approach of “airbagging” to soften its landing — instead, it will descend through the Mars atmosphere using a retrorocket jet pack.
