Rosetta’s Structural and Thermal Model – a replica of the final flight model, produced for initial testing – being prepared for vibration testing on the Multishaker facility at the ESTEC Test Centre in Noordwijk, the Netherlands, at the start of 2000. The testing subjects the spacecraft to the equivalent forces of a space launch. Rosetta's main 2.2 m-diameter high-gain antenna is seen, with one solar wing folded to the spacecraft’s right side.
