But what if it’s not fine? Even back in 1996, before a single component of the ISS was launched into orbit, NASA foresaw the possibility of an even worse worst-case scenario: an uncontrolled reentry. The crux of this scenario involves multiple systems failing in an improbable but not completely impossible cascade. Cabin depressurization could damage the avionics. The electrical power system could go offline, along with thermal control and data handling. Without these, systems controlling coolant and even propellant could break down. Unmoored, the ISS would edge slowly toward Earth, maybe over a year or two, with no way to control where it is headed or where its debris might land. And no, we could not save ourselves by blowing the station up. This would be extremely dangerous and almost certainly create an enormous amount of space trash—which is how we got into this hypothetical mess in the first place.
陆逸轩：并不是某一件具体的事情，而是情绪每天都在变化。重新参赛一开始只是一个想法，但当它变成现实，尤其是5月份公布名单的时候，一切就完全不一样了。之前只有身边家人、朋友知道，但当全世界都知道你要参赛时，那种心理状态是完全不同的，我必须真正为这一刻做好准备。但比赛过程中的压力和困难，其实是无法预先准备的。我很难用语言准确描述，除非你真的在现场，陪我经历了那一切。光是一次次重新走上华沙爱乐大厅的舞台，就需要巨大的勇气，尤其是第三轮之前。随着轮次推进，压力会不断累积，早期阶段你还会觉得自己有一些空间，不一定非要达到最好的状态，但越往后，每一轮对最终结果的影响越大，淘汰的可能性也越大。压力在第三轮前达到了一个几乎难以承受的程度。很多人都给了我建议，但最终的决定只能我来作。因为没有任何一个人可以百分之百地了解我所有的考虑，以及我当下真实的心理状态。最后要什么、不想要什么，只能由自己来承担和决定。，更多细节参见下载安装 谷歌浏览器 开启极速安全的 上网之旅。

Shortcuts: For common scenarios, we pre-calculate the travel time/distance (the "shortcut") between border points within the same cluster and also to border points of immediately adjacent clusters.
