Close-up of the Herschel flight model telescope with the large 3.5-metre diameter primary mirror and the smaller secondary mirror on its hexapod support structure.
The blue wiring is a cable harness connecting the secondary mirror and its supporting structure (hexapod) to a set of motion sensors (accelerometers) that will be used during the upcoming vibration testing of the spacecraft.
