The last weather forecast has confirmed satisfactory conditions, with one further weather forecast due at 9.43 pm.

20:10 CET "The countdown is proceeding as expected", says Arianespace Flight 145 Mission Director Bernhard Puygrenier at the press conference in the Jupiter conference room.

12:00 CET Ariane 5 and Envisat's roll-out seemed to go without a hitch but around 6pm local time an anomaly with the venting at the level of the Vehicle Equipment Bay was discovered.
Technicians worked overnight to check the problem and today's roll-out started at 8am local time, taking one hour. It takes another hour to finish connecting the launcher to the launch pad. This leaves the launch still on schedule, with final countdown set to begin around 11am local time for a 10.07pm launch.
