Gaia deployable sunshield during deployment


Date: 27 October 2011
Satellite: Gaia
Depicts: Deployment of DSA
Location: Astrium, Toulouse, France

Gaia Deployable Sunshield Assembly (DSA) during deployment testing at Astrium Toulouse. Since the DSA will operate in microgravity, it is not designed to support its own weight in the one-g environment at Earth's surface. During deployment testing, the DSA panels are attached to a system of support cables and counterweights that bears their weight, preventing damage and providing a realistic test environment. The flight model thermal tent is visible inside the deploying sunshield and the mechanically representative dummy payload can be seen through the aperture in the tent.
