29 April 2009After the successful fuelling of the Planck spacecraft in the S5A building a week earlier, the spacecraft was transferred to the final assembly building (Bâtiment d'Assemblage Final, or BAF), where it now has been mated with the Ariane 5 ECA launcher.
14 April 2009The past four weeks have been dedicated to the final Planck spacecraft preparations in the S1B cleanroom. The spacecraft is now ready to move to the S5A building for fuelling.
12 March 2009The three scientific instruments on the Herschel payload have passed their functional tests and have been declared 'good to go'. This marks another milestone in the steady progress being made in preparing the spacecraft for launch.
11 March 2009With the nominal launch date a few weeks away, the functional tests of the spacecraft sub-systems are nearly all completed and Planck has undergone its final cleaning during which the spacecraft's surface was closely inspected in UV light
4 March 2009The last week of February has seen several important launch preparation activities with the Planck spacecraft, including the first functional tests, the spacecraft alignment stability tests, as well as the completion of the solar array integration
27 February 2009Following its arrival at CSG the Herschel spacecraft was unpacked and inspected. The first of a series of final preparations to ready the spacecraft for launch - the final cleaning of the primary and secondary mirror - was completed.
23 February 2009The Planck spacecraft has arrived at the launch site in Kourou, French Guiana, and has now joined the Herschel spacecraft in the S1B cleanroom, ready for functional tests.
13 February 2009The Herschel spacecraft has left Europe on the evening of 11 February on a flight with a large Antonov cargo airplane that has taken it to Rochambeau airport in French Guiana
21 January 2009On Thursday, 8 January 2009, the Herschel flight model spacecraft was lifted out of the Large Space Simulator at ESTEC, where it has successfully completed the last series of environmental tests. It is now completing a sequence of final functional tests before its departure for the launch site in Kourou.
17 November 2008In a series of dedicated tests the Planck flight model spacecraft has successfully demonstrated its ability to reach and maintain the extremely low operational temperatures required for its sophisticated instruments, down to 100 mK for the HFI detectors
