ESA: Herschel and Planck Launch Postponed

News Release • April 20, 2009

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 a few days.

A new launch date for Herschel and Planck will be announced shortly.

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