The Philae lander has separated from the Rosetta orbiter, according to ESA, and is now on its way to becoming the first spacecraft to touch down on a comet (Comet 67P/Churyumov-Gerasimenko), with confirmation expected in a one-hour window centered on 16:02 GMT (11:02 AM EST) today (Wed. Nov. 12). The first image from the surface is expected some two hours later.
