PickVidsNuclear Propulsion in Space
推荐理由
This video is worth checking out if you haven’t seen it yet.
说明
这是2017年由US National Archives发布的一部纪录片，主题归在Space exploration & spaceflight。它讲的是nuclear thermal propulsion这一支里的具体问题，而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成：A 1968 NASA film from the US National Archives explaining why the US needed a nuclear rocket and how the engine works. It also shows combined nuclear and chemical stages for a manned Mars mission.这些读者给出的理由，核心是：HN people link it as an old-timey explainer for nuclear thermal propulsion, and as evidence these engines were already built and tested.它贴着当时的技术，看的时候要记得那是那个年份的判断。从2018年到2020年，有2位不同的读者在2个不同月份把它推荐出来，其中明确叫别人去看的有0次。适合先建立人物和来龙去脉的人。看完要能说出这件事是怎么发生的。如果已经会了基本定义，就把注意力放在它怎么把nuclear thermal propulsion变成能跟着复述的例子。
