今年6月,我国执行首次载人空间交会对接任务,实现航天员手控交会对接。这距离去年完成的首次无人空间交会对接任务,不过半年时间,而距神七航天员出舱已经时隔4年。再度载人,而且首次有女航天员。中国载人航天工程的这条消息,迅速触动了各界的敏感神经。于是,作为天地往返工具的改进型长征二号F运载火箭,成为扣人心弦的首要环节。从火箭点火到飞船入轨,前后也就10多分钟。但是,这是航天员进入太空的第一步,也是危险性较大的一个环节。火箭研制团队要为此忙上无数个日日夜夜,用“台上一分钟,台下十年功”来形容丝毫不为过。
In June this year, our country carried out the first manned space rendezvous and docking mission to achieve astronaut hand-control rendezvous and docking. This is the first time since last year completed the rendezvous and docking mission no more than six months, but the spacecraft from the Gods astronaut has been an interval of four years. Manned again, and for the first time, a female astronaut. The news of China’s manned space project quickly touched the sensitive nerves of all walks of life. As a result, the improved Long March II F rocket, as a round-trip tool for the world, has become an exciting first step. From the rocket ignition to the spacecraft orbit, before and after also more than 10 minutes. However, this is the first step for astronauts to enter space and is also a more dangerous step. Rocket development team to be busy on this countless day and night, with “a minute on the stage, the audience ten years of work” to describe as not to be done.
