The invention discloses a film spacecraft, and belongs to the technical field of spacecraft design. The thin-film spacecraft comprises a multifunctional body platform, a thin-film propelling device, athin-film camera, a thin-film antenna, a thin-film battery piece, a thin-film sensor, a thin-film actuator and the like. The thin film propelling device stretches the six thin film sails into a hugeregular hexagon sail surface in a supporting rod stretching mode, flight power is obtained under the action of sunlight pressure, and the thin film camera can conduct high-resolution imaging on an observed target. According to the film spacecraft, multiple functions of thin film propulsion, thin film imaging, thin film communication, thin film power generation, thin film sensing and actuation andthe like are integrated; the film spacecraft can complete long-term voyage and large-range space flight tasks, the advantages of a thin film structure technology and a multifunctional structure technology are fused, through depth integrated design of the structure and loads, weight reduction, energy increase and function ratio improvement of the spacecraft structure are further achieved, and the requirements of spacecrafts for high performance and long service life can be better met.
