CALLISTO (Cooperative Action Leading to Launcher Innovation in Stage Toss-back Operations) is a reusable VTVL demonstrator[1] propelled by a small 40 kN Japanese LOX-LH2 rocket engine. It is being developed jointly by the French (CNES), German (DLR) and Japanese (JAXA) national space agencies.
The goals for CALLISTO are to mature and demonstrate the technologies[2] which are necessary to build and operate a reusable launch vehicle, but also to better assess the operational cost of such a vehicle. The first flight was originally planned to occur in late 2020; it has since been postponed to 2025 at the earliest.[3] Following the programme's conclusion, the experiences and technologies gained through CALLISTO will be harnessed to benefit other ongoing and future space programmes, such as the development of the European reusable launcher Ariane Next.[4]
