So after 4 billion miles and 10 years traveling through space, the Rosetta mission dropped it’s lander, Philae, toward the comet 67P (the comet is a.k.a. Churyumov–Gerasimenko) last night. It touched down at 8am PST this morning. The harpoon on Philae didn’t launch so it isn’t anchored, but the lander is still on the surface of the comet so it’s so far a success. Good job, European Space Agency!
This is the first time mankind has ever landed on a comet, and the scientific data and samples are expect to tell us a lot about the beginning of the solar system, and perhaps how water and organic molecules first came to earth.
