Following the final full orbit determination before separation, the Flight Dynamics Team at ESOC confirm that Rosetta and Philae are on the correct orbit and that Rosetta can achieve the delivery trajectory, i.e., it can be at the correct point in space at the correct time so as to deliver the lander onto the surface as planned.

The GO was announced at 19:00 UTC/20:00 CET.

The next Go/NoGo, to confirm that the commands are ready to be uploaded and that the orbiter is in good health, will be made at 00:00 UTC/01:00 CET.
