中文导读
NASA JPL 工程师详解好奇号（Curiosity）探测器在火星表面进入、下降与着陆（EDL）的惊险过程。该任务融合了气动减速、超音速降落伞及天空起重机（skycrane）技术，完整展示了必须全程全自动精准运转的严密时序。
为什么 HN 推它
HN 社区反复推荐的硬核工程经典，被视为工程化解决极限问题的震撼范例，也是搞懂火星着陆原理的首选科普。
「如果你还没看过 NASA 制作的‘恐怖七分钟’视频，一定要去看看。」HN 网友原话：If you have not watched the seven minutes of terror video produced by NASA, you absolutely must.
英文原摘要（HackerTube / Claude 整理）
NASA JPL engineers explain the final minutes of the Curiosity rover's entry, descent and landing on Mars, which combined aerobraking, a parachute and a skycrane. It lays out the tight sequence of events that all had to work automatically.
HN repeatedly recommends it as an awe-inspiring example of engineering problem solving and the go-to explainer on how Mars landings work.
HN 上的提及
I get goosebumps every time I watch this, absolutely amazing problem solving.

Far more things have to go right in order for JWST to become operational.
I highly recommend watching this video from JPL to give you an understanding of where such tools excel.
The robotic program has a very good track record of successes
