说明
这是2019年由Kurzgesagt – In a Nutshell发布的一部讲解,主题归在Space exploration & spaceflight。它讲的是space tethers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:Kurzgesagt explains the skyhook, a rotating cable with a counterweight that could catapult spacecraft from Earth orbit toward deep space. It covers why it would make space travel cheaper and more efficient.这些读者给出的理由,核心是:Used as the accessible reference for skyhook and space tether ideas in HN discussions of Mars transit, launch and space elevators.讲法不绑某一条新闻,过几年仍然可以当材料看。从2019年到2024年,有1位不同的读者在1个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把space tethers变成能跟着复述的例子。
