Rosetta: Harpoon a Comet at 25,200 MPH - Matt Taylor

Many around the world have been captivated by the Mars Curiosity Rover, leaving tire tracks on a distant planet for the first time. But Matt Taylor works on a different space mission - one he says is even cooler than Curiosity. He helped the European Space Agency send Rosetta into space, which is a mission to land a probe on a comet traveling 25,200 miles an hour. As Taylor explains it, the space craft will "harpoon" the comet and reel itself in to gently "kiss" its surface and screwing into the rock. Taylor says Rosetta will help teach us about the ingredients present when the universe began.
