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.
天色渐渐暗下来,夕阳把大地染成淡淡的金棕色。暖风吹拂下,我把衣领松开,转身缓步往回走,把周边所有树木都留在身后的暮色里。它们或许也在目送我,照例把那些有关生命、生发的腹稿,继续含在抿紧的苞唇里,只是在春风吹过时,每根枝条的顶端都争相报以会心的点头致意。
