Europe plans comet landing

El Jefe writes "The European space agency has plans to land on (a shoot a harpoon into) a comet. The spacecraft is called Rosetta, and is supposed to rendezvous with the comet Wirtanen in 2012. " And all this time I thought cheesy Hollywood blockbusters where astronauts landed on asteroids had no scientific basis. I find it interesting, however, that the spacecraft will secure itself to the comet through the use of a harpoon.
