Graphical timeline of the Philae landing
Rosetta moves from lower right to upper left in this diagram. T0 -- the time of separation -- is November 12 at 08:35 UT, according to the spacecraft's clock. "GONOGO" points along the timeline indicate places where the spacecraft waits for permission to proceed from Earth before performing irreversible actions like separating the lander. With a half-hour one-way light time between Rosetta and Earth, it takes at least an hour for Rosetta to send telemetry to Earth and then receive an instruction in response to that telemetry.
