The Maia rocket is a future orbital reusable launch vehicle under development by the French startup MaiaSpace, a wholly-owned subsidiary of ArianeGroup. A two-stage rocket, it will consist of a first stage with three Prometheus engines as well as a re-ignitable second stage with a single Prometheus engine. An optional Colibri kick stage could be added if need be, powered by a cluster of engines whose development has been outsourced to the Polish institute Łukasiewicz–ILOT.
