9月29日,中国首个空间实验室——“天宫一号”目标飞行器在甘肃酒泉发射成功。不久,“神舟八号”飞船也将发射升空,在太空中与“天宫一号”实现首次无人交会对接。这标志着我国载人航天工程又一次实现突破。空间交会对接是载人航天活动的三大基本技术之一。所谓三大基本技术就是载人航天器的发射和返回、空间出舱活动、空间交会对接技术。只有掌握它们,人类才能自由出入太空。作为中国载人航天工程中的重要一环,“神七”解决了航天员太空出舱活动的问题,“天宫一 On September 29, China’s first space laboratory - ”Tiangong One“ target aircraft was successfully launched in Jiuquan, Gansu Province. Soon, ”Shenzhou 8 “ spacecraft will also launch spacecraft, in space and ”Temple One " to achieve the first rendezvous docking. This marks another breakthrough in China’s manned space project. Space rendezvous and docking is one of the three basic technologies for manned space activities. The so-called three basic technologies are the launch and return of manned spacecraft, space-out activities and space rendezvous and docking technology. Only by grasping them can human beings freely access space. As an important part of China’s manned space project, God 7 solved the problem of astronauts’ spaceship activities in space.
