Deployment test of the QM deployable sunshield
On 29 June 2009 the qualification model (QM) of Gaia's deployable sunshield arrived at the ESTEC test facilities for thermal tests inside the Large Space Simulator (LSS).
Before the tests inside the LSS, a deployment test of the QM sunshield was performed in the cleanroom. This view shows the QM sunshield during the deployment.
The gold-coloured blanket of multi-layer insulation (MLI) is the Sun-side blanket of the sunshield. Like the parallel-installed shadow-side blanket behind it, it is made up of fixed sections attached on to the three rectangular frames, and two foldable sections between the frames.
