Maia

The Maia rocket is a future orbital reusable launch vehicle under development by the French startup MaiaSpace, a wholly-owned subsidiary of the ArianeGroup. The first stage is powered by 3 Prometheus gas generator methane/LOX engines developed under ESA's Future Launchers Preparatory Programme, with the first stage booster returning to a barge at sea. The second stage is powered by a single Prometheus engine, with restart capability. An optional Colibri kick stage could be added to provide enhanced mission flexibility as well as performance to LEO.
