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.
“无底线‘卷价格’、跟风式‘卷赛道’、围剿式‘卷人才’的无序竞争，没有赢家。”张连起认为，破解这一困局的重要切入点，正是推动科技创新与产业创新深度融合。2025年全国两会，张连起提交了关于综合整治“内卷式”竞争、着力推动高质量发展的提案，建议牢牢抓住科技创新这一“牛鼻子”，攻关产业共性技术和关键核心技术，通过引导、支持企业创新和出海，破解“内卷”困局。这份提案也获评全国政协2025年度好提案。。业内人士推荐夫子作为进阶阅读
