On November 12 at about 6:35 UT, Rosetta will place itself on a collision course with comet Churyumov-Gerasimenko. Two hours later, the Philae lander will separate. Another 40 minutes after that, the orbiter will perform a divert maneuver to put it into a relay orbit. Landing is expected to happen at about 15:35 UT, with confirmation received on Earth about 30 minutes later. (Clip from this longer YouTube video)
