兩個月前,一場世紀大火造成168人死亡,宏福苑全數1984戶的居民失去家園,現有逾4000名居民四散在不同地區的應急安置處。BBC中文梳理大火至今就長期安置的主要論述,以及災後重建慣常會遇到的主要難題。

Mostly. This is because, theoretically, we could still save the ISS and move it into higher orbit. NASA has calculated that propelling the station more than 640 kilometers above Earth would keep it alive for 100 years—and also require at least 18.9 metric tons of propellant. That’s roughly 2,000 airline carry-ons. A thousand years would require at least 36 metric tons. If that doesn’t seem like very much, consider the fact that, right now, no vehicle can transport that amount of gas to the station.
