用途广泛空间站具有体积大、功能强和运行时间长等优点,是目前开发太空资源的优良平台。但犹如一座航天母舰的空间站自身无法进行天地往返,需用宇宙飞船等天地往返运输器与其交会对接,才能进行人和货物的接送。利用空间交会对接技术可把宇宙飞船与空间站在结构 Wide Range of Applications The space station has the advantages of large size, strong functions, and long operation time. It is an excellent platform for the development of space resources. However, a space station that is just like a space carrier cannot make a round-trip to the world itself. It is necessary to use a space shuttle and other space shuttles to connect with it to connect people and goods. Using Space Rendezvous and Docking Technology to Spacecraft and Space Stations
