Default Herschel/Planck to launch 5/6


Herschel/Planck to launch 5/6
April 8th, 2009

With the additional checks related to the flight worthiness of the
Herschel telescope now completed, ESA and Arianespace have set the
launch date of Herschel and Planck for 6 May 2009.

Over the last few days, during the final cross-check of the Herschel
telescope documentation carried out by an independent panel of experts
led by the ESA Inspector General and Arianespace, it has been confirmed
that the required safety margins are met and the telescope is fully
qualified for launch.

The Herschel telescope primary mirror, the largest ever to be launched
in space, is a novel and advanced concept using 12 silicon carbide
petals brazed together into a single piece; it is one of the major
technological highlights of the mission.

Herschel and Planck will start their journey in space on board an Ariane
5 departing from Europe’s Spaceport in Kourou, French Guiana. The final
preparations for launch that had been suspended temporarily will now be
resumed, the activities include fuelling of the two satellites and
filling of the Herschel cryostat with helium.
