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.

2024年，第四次全国文物普查队的队员们背着帆布包、拿着专业测绘仪器，踏遍陇中沟壑。他们在我们村找到这片被时光遗忘的黄土城垣，实地调查、拍照、测绘、数据采集，以“张川城遗址”文物的身份进行了认定。普查队员还查阅了大量史料，一步步揭开故城的过往——它曾是交通要道上的军事重镇，东连会宁西宁城，西接安定安西城，是安定区“四普”中极具价值的新发现城址类文物。
