I mean, I’d have to be dead or completely incapacitated.被网有调侃为“价值三十亿美金的名画”于是第三次发射被提上议程：“这枚400英尺高(122米)的巨型火箭计划于美国东部时间周四上午8点(北京时间周四晚8点) 开始的110分钟窗口期（launch window）任意一个时间内，从Space X 位于德克萨斯州博卡奇卡的Starbase发射升空。”当然，发射全过程也有在社交媒体X和其官网同步直播，不知道昨天有观看的小伙伴吗？The time has come for Starship to embark on its third test flight, during which the megarocket will once again be pushed to its limits and demonstrate advances made since the previous flight last November.The 400-foot-tall (122-meter) megarocket is scheduled to blast off from SpaceX’s Starbase facility in Boca Chica, Texas, at roughly 8:00 a.m. ET on Thursday, March 14, with a 110-minute launch window available. The company’s livestream will be made available on X and its website, with the broadcast starting at 7:30 a.m. ET. Of course, this is contingent on favorable weather conditions.如果你好奇什么是 SpaceX, 它是做什么的，为什么这么重要...相关阅读欢迎点击下方音频或者查看下方文稿了解哦~ Hi everyone, and welcome back to Geek Time. 欢迎回来【极客时间】. Hi, Brad.Hi, Lulu.So in today's Geek Time, I thought we continue to talk about Elon Musk. All right. Because he's done a lot of really outstanding things. I mean really out-there things, right? You know, people, even if you’re not into science technology, you've heard of things like SpaceX, Starlink, 什么星链呐SpaceX,还有像各种各样的这种rockets, I thought we can start with SpaceX, what does it actually do? And why is it so impressive? Well. A SpaceX was a company, it was started in 2002. The whole reason was there was a competition, and that competition was to design a rocket that could be sent into space and then reused within 2 weeks. And SpaceX was able to win that competition, but that the whole idea is to reduce cost for putting things into space. They are often referred to as a payload, but just something like people or in a satellite or parts for the space station, and do it in a cost effective way. 对, 那个叫载荷吧, 就是那个 payloads. So this was started by what, the US government, you said this competition?I don't remember if the government started, but like the government wanted this, because NASA, NASA could do a lot, but they had to have other people looking at us. NASA is kind of limited as to what it can and can't do. And so they wanted more of like the private sector to go out and start doing some of this stuff as well. And so this whole competition was created as a way to get that going.So basically, private companies like SpaceX they were competing in trying to make fully reusable rockets? You said reusable within 2 weeks.Right.What about the cost? Do they also reduce cost?That's the whole point. It's like if you can reuse the rocket, then you can reduce the cost by a lot. SpaceX has been able to get their rocket launches down to about or 67 million per launch, which is 10 times cheaper than what NASA has been able to do this far. Wow, 10 times, mainly because the rockets are reusable or immediately reusable. I see. I see.
