通过协议,别国航天员搭乘苏联载人航天器进入太空,同苏联航天员一起做两国的太空科学实验项目,这种所谓“国际航天员”合作形式,深受苏联与协议国的重视,也是苏联航天技术发展总政策的组成部分。因为这种合作对双方都有利,它可促进载人航天技术的发展,增进国际间的友谊,使载人航天国际化。 Through the agreement, astronauts of other countries took the Soviet manned spacecraft into space and made space science experiments between the two countries with the astronauts of the Soviet Union. The so-called “international astronaut” cooperation form has won the attention of the Soviet Union and the agreement countries. It is also an integral part of the general Soviet space technology development policy. Because this cooperation is beneficial to both sides, it can promote the development of manned space technology, enhance international friendship and internationalize manned space.
