Envisat / Polar Platform test preparations

The flight model of the Polar Platform Service Module (SM) under final preparation for thermal balance/thermal vacuum testing in ESTEC's Large Space Simulator. The spacecraft's multilayer insulation is evident. The SM is inverted, i.e. the launcher interface is at the top and the Payload Module interface at the bottom. [Image Date: 01-12-96] [97.01.004-026]
