The objective of the DARWIN System Assessment Study is the definition of the overall architecture and the preliminary design of the DARWIN mission. This includes an operational orbit at the Second Lagrange Point of the Sun-Earth system (L2), a launch and transfer scenario, and a spacecraft and payload design which ensure that the mission requirements can be fulfilled. The specifications of the subsystems have to be derived, critical items and drivers have to be identified, and required technology development activities have to be proposed in order to allow for establishing a roadmap towards the verification of the science performance feasibility. The DARWIN System Assessment Study is divided into two phases. Phase 1 is concerned with a review and trade-off of different concepts concerning the payload, the space segment, and the mission. Phase 2 is devoted to a detailed design of the payload and the space segment, as well with a consolidated mission design. A third phase is foreseen for design consolidation.
