Herschel-SPIRE Testing at ESTEC
23 October 2006Between 16 and 21 October, the Herschel SPIRE instrument underwent a series of tests at the ESTEC test centre in Noordwijk, as part of the Structural Thermal Model test campaign.
Planck Leaves ESTEC for Alcatel Alenia Space
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.
Herschel and Planck Meet for the First Time
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...
Second Round of Cryostat Testing in LSS
29 August 2006The Herschel core cryostat is back at ESTEC for verification of its thermal and lifetime performance under close-to-space conditions inside the Large Space Simulator.

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).
Transfer of Planck FM Telescope to Large Space Simulator
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.
Planck Telescope FM Arrives at ESTEC
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.
