As you may have heard the ESA's spaceship, Rosetta, as been orbiting a comet out in deep space for several months. They have been studying the beast for a landing site and have at last settled upon one.
Tomorrow the lander, Philae, will detach herself from the mother ship and move to its designated LZ. This will, as you well know, be the first time a human craft has landed on a comet. Heck, its the first time we put a craft in an orbit around a comet.
