A controlled deorbit requires the use of several core systems, including those for communications, power, and avionics. Some of the ISS machinery was not specifically certified to perform in a depressurized environment. (NASA believes that critical systems would remain operable, based on technical analyses, and emphasizes that many of these systems are already used in vacuum.) Another thing to worry about: the ISS losing control over its orientation in space. The spacecraft could start tumbling, flipping the station’s solar arrays away from the sun, taking the primary source of power with it.
从春风唤醒生命的感触中，忽然想起了贺知章的名句：“不知细叶谁裁出，二月春风似剪刀。”可再一琢磨，诗里春风固然灵巧，用词确有新奇绝妙处，但总不免失之于锋芒过露。而自己眼见的一切，或许更近于“随风潜入夜，润物细无声”的意味。这风似乎不像剪刀，没那么利落、分明的姿态，倒更像是气是水，是弥漫的、渗透的、无处不在的柔情。它不张扬自己的到来，只是默默地让柳丝自己去绿，让草芽自己去长，让蛰虫自己去醒。像个高明的导演，自己隐在幕后，只让万物去演绎生命的繁华。
