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.

Ring-2.5-1T 的表现:
For implementers, backpressure adds complexity without providing guarantees. The machinery to track queue sizes, compute desiredSize, and invoke pull() at the right times must all be implemented correctly. However, since these signals are advisory, all that work doesn't actually prevent the problems backpressure is supposed to solve.
另一方面,吴德沛把更多精力投入到调研。去年全国两会前,他围绕创新药可及性展开系统调研,走访医疗机构、药企和保险机构,与国家医保局、国家卫生健康委、金融监管部门等多方交流,梳理创新药从研发到支付的堵点。“单靠基本医保,很难承载高值创新药支付需求,必须让商业保险参与进来。”围绕这一目标,吴德沛反复完善建议,提出建立“基本医保+商业保险+社会救助”的衔接机制,推动编制商业健康保险创新药品目录,多次参与专题座谈并持续跟踪政策进展。吴德沛说:“履职不是提完建议就结束,而是要持续跟进。”
