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. The still-in-development SpaceX megarocket Starship might be able to haul a significant percentage, but it would struggle to dock with the station, according to the space agency’s estimations.
起初，狗显然有些不适应，尤其是晚上回到房间以后，它便时不时要嚎叫一番。而它一有动静，隔壁的狗有时也要跟着吠，甚至于它嚎够歇菜后，“邻居”们又起了兴致，叫个没完。我一度担心，狗在这种环境里，能睡好么？当然，事实证明我想多了，夜深了，狗趴在沙发上睡着了，大概还在做梦奔跑，腿一抽一抽的。
