Philae is currently scheduled to separate from Rosetta at 1:03 a.m. PT time on Wednesday, and touch down on the comet should happen just under seven hours later at 8:02 a.m.
Philae and Rosetta have already ticked off the first box on their "Go/No go" checklist for attempting the landing -- mission control has confirmed that Rosetta is on a correct trajectory. We're still awaiting confirmation that the separation commands are ready for upload, which will be followed by other final preparations for separation and a required pre-separation maneuver. If all this goes as planned, the final "Go" for separation will be given.
At this point, the video feed from mission control in Germany is already live below, but the real action isn't likely to start until separation draws closer Tuesday evening here in the United States. While you're waiting for history to be made, get caught up on our coverage of justthe landing will be, and what a and up close.
