24 October 2007The recently concluded test campaign of the Planck Radio Frequency Qualification Model (RFQM) has proven the planned RF verification method which will now also be used to test the Flight Model of the Planck telescope early next year
13 September 2007Engineers from Dutch Space are installing the flight model Herschel solar array and sunshade in the Large European Acoustic Facility at ESTEC, where the assembly will be subjected to noise levels that simulate launch conditions.
23 February 2007The Herschel Cryostat has successfully completed a second test campaign in the Large Space Simulator, which was set up to verify the effects of repairs made after the first round of tests.
20 September 2006On 12 September 2006, the Planck FM telescope, housed in the Planck Spacecraft Container, was loaded onto a truck and left ESTEC to be transported to the premises of Planck prime contractor Alcatel Alenia Space France in Cannes, France.
1 September 2006The primary reflector for the Planck spacecraft flight model (FM), on its way back to Cannes after a test campaign in the ESTEC LSS test facility, meets for the first time the cryostat belonging to the Herschel spacecraft. The Herschel cryostat has just arrived at ESTEC for a test campaign that will also be performed in the LSS and will run over...
15 August 2006The Planck Telescope Flight Model has performed well during a two-week test in cold-vacuum conditions down to -178 degrees Celsius, and the results of the measurements are now being studied in detail.
13 July 2006During the last week, specialist from the AAS-F and ESA Planck project have carefully aligned the Planck Telescope Flight Model as well as prepared and verified the videogrammetry set-up foreseen to verify the Planck telescope alignment in vacuum and cold conditions inside the Large Space Simulator (LSS).
29 June 2006On 28 June, the Planck Flight Model Telescope was transferred to the Large Space Simulator at ESTEC, where it will undergo a major test under vacuum and at low temperatures (~100K) in the coming weeks.
27 June 2006Saturday, 24 June, the Planck telescope flight model transport arrived at the ESTEC site in Noordwijk, The Netherlands. Here it will undergo videogrammetry testing at low temperatures inside the Large Space Simulator to measure the telescope's deformation under these conditions.
23 June 2006The Planck telescope Flight Model (FM) has been put on a transport at Alcatel Alenia Space in Cannes for its journey to ESTEC in Noordwijk the Netherlands. Here it will undergo deformation testing at low temperatures (100-110K) in the Large Space Simulator.
24 May 2006The Planck telescope will be tested soon at low temperature (100-110K) in the Large Space Simulator test facility at ESTEC. The objective of this test is to measure the deformations of the fully integrated Planck Flight Model telescope at low temperatures with video-grammetry.
8 March 2006The final preparations for the 17-day thermal test campaign of the Planck Flight Model are well under way at the Centre Spatial de Liège.
6 March 2006The Herschel Structural Model spacecraft is being prepared for a series of qualification tests in the acoustic test chamber, LEAF, in ESTEC.
