Hello all,

An offical announcement about the launch delay is posted at

http://www.esa.int/SPECIALS/Herschel/SEMG1Z9NJTF_0.html.

It says:

"Herschel and Planck launch postponed

Due to an anomaly discovered during tests on a subassembly
identical to the one on the Ariane 5 launcher, Arianespace has
decided to carry out additional checks, which will take several
days.

A new launch date will be announced shortly.

The two satellites are in perfect condition at the launch site in
Kourou, French Guiana."

Cheers,

Matt
