The Russian Orbital Service Station (Russian: Российская орбитальная служебная станция, Rossiyskaya orbital'naya sluzhebnaya stantsiya) (ROSS, Russian: РОСС)[2] is a proposed Russian orbital space station scheduled to begin construction in 2026. Initially an evolution of the Orbital Piloted Assembly and Experiment Complex (OPSEK) concept, ROSS developed into plans for a new standalone Russian space station built from scratch without modules from the Russian Orbital Segment of the ISS.[3]
