Thanks for the link. it was amazing that SpaceX accomplished this huge project and of course, more to come, right? :-)

特君对航天很感兴趣噢。 “留心一下”? 非常留心,非常动脑筋,赞! Lots Of Idiots In Private Boats Swarmed Where The SpaceX Dragon Capsule Splashed Down From The ISSThere hasn’t been a splashdown of an American crewed space capsule since the Apollo capsule from the Apollo-Soyuz joint U.S.-Soviet Union space mission in 1975, at least not until yesterday, when astronauts Bob Behnken and Doug Hurley returned to Earth from the International Space Station in orbit, splashing down just off the coast of Pensacola, Florida. They were met by recovery teams, and, as an unexpected bonus, by a bunch of dipshits in private boats who got in the way of recovery operations and could have placed themselves in danger. Welcome to Florida!

对,是有点兴趣。Not like "shake his beard", 航天,航空,及航母、潜艇等等are all man's topics, I guess. Thanks for the link.

第6分14秒,一个回收队员爬上返回舱,把起重机吊绳穿进降落伞的连环里,自己跳进水里。感觉跳下水比爬下来也容易一些。
两宇航员怎么出舱门也有点悬,因为他们必须“爬”到舱门口,回收队员才能把他们搬出来,抬到担架上。从失重状态下回到地球引力之下,段时间内两腿不能承重,.......

英国本月8日、9日分别在威尔特郡(Wiltshire)、牛津 (Oxfordshire)出现麦田圈,牛津的麦田圈有4个圆形结构,最外圈1个圆形,往内2圈是由相反方向的直角三角形构成的圆圈,最内圈则像是太阳;而在威尔特郡出现的麦田圈,则被眼尖的网友发现长得很像三硝基胺的化学分子图,这种物质被认为未来可能用于最有效和污染最小的火箭推进剂氧化剂,网友因此认为这可能与马斯克在推特的发言有关。 威尔特郡出现的麦田圈被认为与可用于火箭燃料的化学物质分子图高度相似。 据了解,麦田圈主要出现于欧洲与北美洲,形成原因不明,但可分为"支持部分麦田圈非人为"、"支持全部麦田圈皆人为"两大派,前者认为若非出自于广告、吸引游客所制造的麦田圈,多为超自然力量或外星科技有关,植物才能全倾倒后继续生长,若为人为构成,植物通常会受到影响而死亡。

航天迷肯定听说过 Wernher von Braun? Chapter 1 | Part 1 | Chasing the Moon | American Experience | PBS 对中文名字 冯·布劳恩 才有一点印象。 在维基里看到,他小时候同时学大提琴和钢琴,曾经打算学指挥,自己也谱过曲;十多岁时妈妈给他一个望远镜,这就给他打开了世界的另外一个大门。....... 一个人首先得有天资,然后是机会。机会是偶然的,天资是必然的。有天资怎么都会顶尖冒头。 谢谢推荐。

还有化学分子图麦田圈,有趣!

哦天呐,这个同3.1416有关的视频是我到目前为止所看到的最让人惊愕的麦田圈。这就让我从根本上不会去相信人为的可能,虽然我也一直认为麦田圈是来自宇宙不明物体的杰作。 谢谢分享!

SpaceX will launch 4 astronauts into space for NASA today. Here's how to watch live. The flight is scheduled to blast off from Pad 39A here at NASA's Kennedy Space Center at 7:27 p.m. EST (0027 GMT on Nov. 16) on a SpaceX Falcon 9 rocket carrying a Crew Dragon capsule with four Crew-1 astronauts members strapped inside.
