How Much Do Rockets Pollute? Are They Bad For Our Air?
推荐理由
I highly recommend to everyone who is concerned about this.
说明
这是2020年由Everyday Astronaut发布的一部讲解,主题归在Space exploration & spaceflight。它讲的是rocket launch emissions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:Everyday Astronaut's Tim Dodd runs an hour-long, data-driven analysis of what rockets actually emit and how that compares with airliners and other industries. It breaks down exhaust by propellant type, per-passenger and total emissions, and ways launches could be cleaner.这些读者给出的理由,核心是:HN commenters cite it whenever rocket launch pollution comes up as a rebuttal to alarm, since it shows launches are small next to other sources.讲法不绑某一条新闻,过几年仍然可以当材料看。从2020年到2023年,有6位不同的读者在6个不同月份把它推荐出来,其中明确叫别人去看的有1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rocket launch emissions变成能跟着复述的例子。
