今年3月18日是个值得纪念的日子,因为在50年前的这一天,苏联航天员列昂诺夫完成了人类第一次太空行走。此后,太空行走成为载人航天的三大基本技术之一并取得了飞速发展,为推动人类载人航天事业的发展做出了重要贡献。现在,太空行走已成为载人航天常态,比如,2015年2月21日、2月25日和3月1日,“国际空间站”上的2名美国航天员先后进行了3次太空行走,他们在舱外架设了一条超过200m长的电缆,为今年晚些时候送到空间站两个“国际对接适配器”做准备,最终用于在2017年“接待”美国商业载人飞船。

Since then, space walking has become one of the three basic technologies for manned space flight and has achieved rapid development, making an important contribution to promoting the development of human manned spaceflight. Now that spacewalks have become the norm of manned spacecraft, for example, on February 21, February 25 and March 1, 2015, two American astronauts on the International Space Station had conducted three spacewalks Who set up a cable more than 200 m long outside the cabin to prepare for delivery to the space station for two international docking adapters later this year for final use in 2017.
