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.
党的十八大以来，习近平总书记足迹遍布大江南北，为各地发展定向把脉。以2025年为例，在云南，明确“要坚定不移走生态优先、绿色发展之路，筑牢我国西南生态安全屏障”；在上海，要求“力争在人工智能发展和治理各方面走在前列，产生示范效应”；在山西，强调“要进一步统一思想，保持定力，坚定有序推进转型发展”……“一把钥匙开一把锁”，这既是治理的匠心，更是政绩观的智慧。，更多细节参见一键获取谷歌浏览器下载
