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.
Ранее военный эксперт, полковник в отставке Анатолий Матвийчук рассказал, что ВСУ активизировали действия только на одном направлении — запорожском.

"[In] the 1960s [it] turned out, in hindsight, we had a near-endless schedule margin there," Isaacman said. "That is certainly not the case today. I'd say this is very, very close from a timeline perspective."
基于这一背景,云耀深维在成立之初便确立了差异化发展路径:聚焦微米级高精度金属3D打印,剑指全球最高精度的打印效果。相较于传统常规金属打印100–200微米的公差水平,公司可将打印典型精度提升至2–10微米,典型表面粗糙度(Ra值)优化至约0.8微米,并实现10度以上多种结构的无支撑成型,这意味着微米级金属打印的部件几乎不再需要CNC加工,进而实现成本的有效下降。
