Herschel and Planck to lift off on 14 May


 
Europe's Spaceport, the Guiana Space Centre, Kourou
 
 
28 April 2009
 
Now that additional checks on the Ariane 5 ECA launcher have been completed, Arianespace and ESA have set the launch date of Herschel and Planck for Thursday 14 May.
 
In the meantime, the preparation of the two satellites for launch continues flawlessly at Europe’s Spaceport in French Guiana. Herschel and Planck have already been fuelled with hydrazine. Planck’s three-stage active cryogenic cooler, needed to keep the instruments at extremely cold temperatures, has been filled with helium-3 and helium-4. Herschel's cryogenic tanks are also being filled with superfluid helium.

Planck was also integrated with the Ariane 5 launcher, and is now waiting to be covered with the SYLDA element. This structure is needed to both encapsulate Planck during launch and to support the upper passenger – Herschel.

Updates on the launch campaign will follow on the ESA website.
