A preliminary design of the STE-QUEST spacecraft has been proposed following an ESA study of the mission carried out at the Concurrent Design Facility (CDF) at ESTEC, the Netherlands.
The STE-QUEST spacecraft is expected to weigh about 1400 kilograms at launch, making it compatible with launch on a Soyuz vehicle.
The payload, including the main STE-QUEST instruments and subsystems,would be housed in a cylinder integrated along the spacecraft axis. The external structure would also be used to accommodate the microwave antennas and the 2 laser terminals needed for the operation of the optical and microwave links. Two solar arrays located symmetrically with respect to the spacecraft body would power the spacecraft.
