Alot can happen in a day. Before this afternoon, we (meaning the human race) had never landed a space prome on a Comet. But now we have. Philea, a space probe has just landed on a Comet. Not a very special Comet, but a Comet nonetheless. Today is the 12 of November 2014, just in case you don't know, and it is a pretty historic day due to scientists in Europe (who doesn't love scientists in Europe?).
