科学幻想常常会引发人类的重大发明创造。1865年,法国著名作家凡尔纳在他的科幻小说《从地球到月球》中,描绘了一款人类在太空旅行时需要穿着的特殊服装,这就是现代航天服的最初设想。航天服是宇航员实现太空行走的最关键装备,它不仅是一件衣服,更是一艘小型太空船,一套保障宇航员生命活动和工作能力的个人密闭装备。它可抵御宇宙空间中的真空、高低温、太阳辐射等环境因素对人体造成的危害,时刻保护太空探索者的安全。航天服是从飞行员密闭服的基础上发展起来的多功能装备,从1965年美国人首次成功实现太空舱外活动至今,航天服的外观和细 Science fiction often leads to significant human inventions. In 1865, the famous French writer Verne, in his science-fiction novel “From Earth to the Moon,” portrayed a special garment worn by man for space travel, which was originally conceived in modern space suits. Spacesuit is the most essential equipment for astronauts to walk in space.
