Herschel and Planck launcher fairing opens

An Ariane 5 will carry Herschel and Planck into space. About 30 minutes after launch. The launcher's solid rocket boosters will separate from the upper stage approximately 2.5 minutes after launch, and the fairing will come off about 4 minutes after launch. Following this first Herschel, and then Planck, will separate from the upper stage.
