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
4 August 2008Mechanical tests on the Herschel flight model spacecraft were successfully completed on 3 July 2008. On that day, the last vibration test was performed on the multi-axis hydraulic shaker at ESTEC. The spacecraft is currently undergoing electrical tests and will later be prepared for the forthcoming environmental tests scheduled for September.
26 June 2008The first phase of the thermal balance / thermal vacuum (TBTV) test campaign has started for the Planck spacecraft, which is now inside the vacuum test chamber at Centre Spatial de Liège that is used to simulate the cold vacuum conditions of space
30 May 2008Preparations for the upcoming thermal balance / thermal vacuum (TBTV) test of the Planck spacecraft are well under way at the test facilities of Centre Spatial de Liège. On Monday 19 May, the Planck spacecraft was placed inside the FOCAL-5 test chamber for a fit check.
