The invention discloses a multifunctional service spacecraft which comprises a cargo cabin and an instrument cabin. The multifunctional service spacecraft adopts a special inner and outer double-bearing-cylinder structure; the instrument cabin at the upper part adopts a sealed central bearing cylinder structure; the cargo cabin at the lower part is connected with the central bearing cylinder of the instrument cabin through a section of truncated cone by taking the outer bearing cylinder as a main bearing structure, and is internally provided with a sealed inner bearing cylinder which forms a sealed space together with the central bearing cylinder of the instrument cabin; the instrument cabin is provided with a mechanical arm, a propellant supplementing device and a lightweight spacecraft docking and parking mechanism; the cargo compartment is provided with a spacecraft docking and parking mechanism. The multifunctional service spacecraft is in orbit for a long time, orbit maneuvering can be carried out according to requirements, and the multifunctional service spacecraft has the advantage of high integration and is mainly used for providing comprehensive in-orbit services such as cargo transportation, attitude and orbit control takeover, repair and maintenance, propellant supply and the like.
