回复 74楼 sunleilucky 的帖子 Just read this, so fascinating https://www.quora.com/What-are-the-working-conditions-like-for-engineers-at-SpaceX-or-Tesla-Motors What is it like to work at SpaceX? SpaceX has become quite a large organization over the last few years, yet it still maintains a startup mentality and feel to it. Despite its size there's a fairly flat organizational structure. For example, I reported to the CIO, which was only a couple levels down from Elon. I actually started out as an intern, and converted to full-time after a year of continuously extending the 3 month program. Even when I was an intern though, I felt like a full part of the company. If you do get hired on full-time, you will need to be approved by Gwynne and Elon; they used to actually interview everyone but the company has gotten too large for that. When I, and many of my coworkers, first got an offer from SpaceX, they paid to relocate us and set us up in some nice furnished corporate housing while we settled down and got to work. The factory itself isn't in a great neighborhood; you need a lot of space to build rockets and that doesn't come cheap in LA. It's located in Hawthorne, in between Inglewood and Compton. The neighborhood has gotten safer and nicer since we moved in, but we've had a stray bullet knock out a window before. Photo: Dragon, Octoweb, & Mission Control view from the Mezz. Note: we are not allowed to take and release photos of the factory, so I can only use what has been publicly released. There are almost no private offices, as just about everyone has a cubicle, including Elon. You get pretty much full access to the factory, and can walk around and explore on your breaks. It's amazing to be able to see the process of building a rocket, basically from start to finish. They even have cameras set around the factory, so you can watch what's going on from your desk; I used to like watching what they're making in the titanium 3D printers, or what was on the 'octoweb' video feed. Depending on your department the culture can be quite different. My department was pretty flexible about where and when you work, just so long as you got your work done, where as other departments had 'time cops' and you have to clock in and out. Communication is very open, and even Elon is approachable if you have a good reason. Anyone in the company could email or talk to him. I had even gotten him a birthday gift one year of a 3D printed version of his head on an Iron Man action figure. Not only did Elon have a cameo in Iron Man 2 (see below), part of the movie was shot at SpaceX, and behind one of the elevator shafts (they're glass) there's a life size Iron Man statue signed by Robert Downey Jr. "Hammer's factory is really Elon Musk's SpaceX facility. The people walking in the background are actual employees even though filming there took place at night." - IMDB Photo: 'Iron Musk' Action Figure Video: Elon Musk's Cameo in Iron Man 2 While no one will be forcing you to, you'll end up working crazy long hours, just to keep up with your workload, and because you don't want to leave the place. A phrase I've heard thrown around SpaceX frequently is everyone is their own slave driver. I was frequently there late at night for my job, and I never really felt alone. The factory is always alive and cranking out rockets no matter what time of day or night you go there. Pretty much all employees are involved in the hiring process. That is, just about everyone does phone calls and in person interviews to screen potential candidates for their department. Everyone would have to sign off for a hire to go through, so sometimes it could be difficult to get people through, but that's how we ended up with such high quality talent there. Even with as much as we've expanded recently, we've had headcount and ITAR limitations to worry about as well; everyone wears many hats/works many jobs at SpaceX. Our sister company Tesla, actually runs a fork of the ERP software I worked on there, but since they don't have International Traffic in Arms Regulations to worry about, they can outsource work and hire non-Americans, whereas we couldn't. My job was done by a whole team of people at Tesla. We would work hard and play hard. It was not uncommon for me or other people I worked with to pull 12+ hour days, weekends, but honestly the time flew for me and it was never boring, because I always had interesting work on my plate. Around the office there's some fun stuff like free froyo and coffee, some arcade games, a masseuse (my favorite perk), a relaxation room, and more. Whenever there's a space themed movie coming out, we'll usually buy out all the tickets for a couple showings and send the whole company. I'm actually going to see the Martian with SpaceX on Friday (last week was my last week there, so I still got the free tickets). Oh and SpaceX parties are insane. Elon knows how to throw company Christmas party! They're usually so big that they have rickshaws drive you around the party. Photo: At the SpaceX Christmas party 2013, Elon is in the background The job satisfaction and team camaraderie is like nowhere else. Every time there is a launch, everyone crowds around mission control and cheers it on. Getting your mission patch after a launch was always a very satisfying feeling. If there was ever a failure, you definitely felt it in the air, but it wouldn't stop any of us from working or demotivate us. The pride for the company is unbelievable. How do you spot a SpaceX employee? They're covered head to toe in company swag, and keeps mentioning how they work for SpaceX. To be fair though, it is the only job I have really worked that has had a fan base. More often than you'd think people would come up to me off the street, at bars, at the airport or anywhere in public if I was wearing my badge or any SpaceX gear. If you're a fan of the company, I would encourage you to do the same. I always loved talking to people about my job. Photo: Some of the mission patches I collected during my time at SpaceX. If you're considering working for SpaceX, I would highly recommend pursuing it, as it's an incredibly rewarding experience. The only reason I left is that my post-quantum encrypted communications startup, Cyph, really started to pick up steam to the point where I could no longer afford not to dedicate my full attention to it — from supporting serious stuff like the coordination of smuggling humanitarian aid into Syria, to the initial rollout of an enterprise offering, to ultimately closing a recent $0.5m Seed funding round. If you're interested in checking it out, we have a public beta available which we intend to always be free for regular non-commercial users, and we're currently offering both custom and off-the-shelf enterprise encrypted chat solutions to monetize. I still hope I can go back to SpaceX some day, as I do miss it (maybe if Cyph gets acquired down the line), and help continue the mission to get the human race to Mars. Feel free to ask questions. Depending on the content, I may or may not be allowed to answer it, however most things about the awesome company culture are pretty public.
回复 74楼 sunleilucky 的帖子 看看这个人写的 - Yes, fulfillment is a big part of it. If one is looking at the money, the hours, look elsewhere. I worked a LOT of 16-20 hour days and sometimes took catnaps under my CAD workstation. My record was 42 hours straight with zero time for napping. That was nuts! But, it was necessary because there wasn't anyone else who could do it. At SpaceX it's the same. Sometimes, a certain person literally has to invent a solution in short order. No 2nd shift, no calling for advice, no 'tomorrow is another day', that one person has to solve it now or the mission fails. Certainly, not all jobs at SpaceX are like that, but that kind of ride is definitely not for everyone! For those who say your work degrades with long hours... It does a bit, but there's definitely both a raw talent and a learned skill to doing it well. Normal people don't get the concept because people who do this aren't normal, myself included. As to pay, I got paid very well but I would have done it for free. Just give me room and board and let me weave magic!

再看看去年发射Starship从mexico的视角, breathtaking https://www.youtube.com/shorts/34PjO5rwBiY
至于未来准备怎么去mars https://www.youtube.com/shorts/4nR718ryFnQ
Starship相当于把一栋44层楼 推上太空
再吹一波星链吧 全程几乎没有掉线，信号一直稳定
看看Starship和历史上其他火箭的对比吧
🔥 最新回帖
你好历害啊！
Elon谈过这个事情。他故意多加几发动机。整个系统设计成“少量发动机灭了”依然可以工作。
这样更稳健。就像大型飞机有四个引擎，只要一个工作就能降落。
跟你想的不一样，不是必须每个都正常才能整体工作。
🛋️ 沙发板凳
一身的鸡皮疙瘩，无比羡慕为spaceX工作的
没吹的那么神
要加注十几次的东西，想星际旅行基本是梦
而且，30几台发动机，出事的概率要多大？ 这次就有一台没点火。 这样的话，要设计多少冗余载荷才能发射？
花了那么多钱，真不如踏下心来设计新型发动机或者火箭。
这个东西让人类上火星的可能性不大，
人类移民火星更不可能
这个东西是目前世界唯一，走再最前面的，没有疑问
走这种燃料，抵抗重力， 把人往天上推的方式，也就这样了
人类的基本科技能力，没有啥特别的 根本性的 往外推进
不指望它能移民火星，也不觉得火星移民有多大的意义
星舰未来，一次性可以发射600多Starlink卫星。能recycle，加速空间站建设
SpaceX能让我们人类继续做dreamer就好
我们人类过去的几个decades似乎已经忘记了做dreamer的感觉了
自己已经没有机会了，希望孩子以后能去SpaceX工作
路漫漫其修远兮。
SpaceX 说的很清楚了，这次主要是为了Data。Starship每一次试飞，都有明显的进步。这次完成了所有测试的milestones
跟football 一样，有进步就好。 Add oil!
有一台发动机灭了， 我咋觉得是退步了！
还是那句话谁都逃不过概率。
一台发动机事故率是千分之一， 35台绑到一起事故率是多少， 比较简单的概率题吧！
说明设计冗余还是非常不错的
所以这个大火箭的实际工作负荷要打折啊！
可能几年以后，等starlink价格降下去以后，我们手机都要连Starlink了？
理论上starlink成功全面覆盖以后，全球通话，短信，网络 都能更快也更便宜。不需要再借助海底电缆。
SpaceX真能改变世界！！
地球上空气阻力太大了。 感觉应该在外太空搞个发射站。
一个每天在华人上浪费几个小时的人，居然有脸瞧不起 space X？
根据台湾概率之父算法， 一台成功率99.9%， 35台成功率3496.5% ， 铁板丁丁的成功率 😂
现在能在月球上，
建造出一个基地，
让人能在那里工作生活下来，这个基本上都不太可能，
至于说让什么机器人过去，基本上更是扯
现在也就是空间站。地球轨道上折腾，往远走最多就是探测器
习近平思想学完了？马赛克需要被指明方向哪
他既然计划在火星上生存，就有可能在月球建类似的基地。当然这只是我想当然的
他/她为啥不可以？？他/她在质疑 spaceX 一笼,你在干啥？
你要是能好好说话就好好说话，
你如果词穷了只能靠骂街，就应该把你那个臭嘴闭上。
深空星际旅行不能靠这种化学火箭
目前的驱动原理都是要往外喷东西， 走不远的啊， 你得带多少垃圾工质往外喷来获取动能啊……. 核能也好化学染料也罢只是解决能量部分没有解决工质部分
什么时候造出科幻小说里面那种纯粹靠喷能量驱动的发动机再加上聚变技术， 深空旅行才会成熟
除非人类有 本质性的 科技突破，
这些什么定居月球火星的，基本都是 美好的想象和愿望，
未来是否会有 根本性的 超越现有认知的 科技突破，不知道
听起来 spaceX 是你家的？ 还是说一笼是你养的狗？
尼玛你们俩跟space X 的关系没啥差别吧， 你在这傲娇个屁
其实没必要常驻月球或火星上。
机器人上去，能把资源取回来就就好。
Again , why not give that contract to SPACEX to begin with ? What a waste of everyone's time and all tax payers money .
你能质疑你阿祖不是被迫而是自愿的， 我就不能质疑老马的大火箭风险控制有问题？
这题我会： 凡是失败的， 就说是私人企业不代表美国技术 凡是成功的， 忽然又代表了
刚说了呀，追求星辰大海 - 我们就不要吵吵了，消消气，多想想诗和远方？
完全赞同
FYI: 今天中午波音的 starliner 和国际空间站对接成功，现在就看回收了。starliner 和 space dragon 是互为竞争的关系。starliner 每次发射成本为 7千万美元， space dragon 约为 3千5百万，都比原来 space shuttle 的 1亿3千万少很多。
虽然 starliner 确实整体上不如 space dragon 但是对 NASA 而言，有两家互为竞争从长期而言，是有益的。回看波音在吞并最后一家客机厂商 麦道后，一家垄断，现在搞的焦头烂额。nasa 保留两家竞争是正确的决定。
starliner 还提供了一项新技能：以前美国回收都是在海面回收的，starliner 是在沙漠里回收的，和俄罗斯中国一致。虽然这未必就好，但 track 自己对手的技能也是必要的。
说得好
谢谢答复
SpaceX跟Tesla股票是啥关系？SpaceX今后如果盈利好，会带动Tesla股票上涨吗
啥关系我不知道 -
但是，把星舰上面那个摄像头，分享给Tesla，L5自动驾驶的Visual intake起码不受 天气暴雨冰雹龙卷风 限制了吧 😂
进步是显然的。 离稳定性还差好多。 厉害了就可以坐火箭旅行啦，半小时到任何地方，挺牛的。
应该是两个不同的公司。当然，关系肯定会有一些，毕竟同一个 CEO
是的，化学火箭，工质推进，也就这点本事了。猛禽已经是人类现阶段能拿出来的最好的发动机，最高的室压，最高的推重比，全流量分级燃烧，但是和60年前毛子的毒火箭比起来，其实也没什么特别本质的提高
这是怎么算的，明明是redundancy. 假如只需要三十个发动机，其中五个同时出问题的概率是多少？
波音的两个宇航员已经抵达空间站了。
1个发动机停火，就要几个发动机损失推力，抵消这个发动机的，来保证正常飞行。
5个同时停火，就直接掉下来了。什么redundancy都没用。 所以设计冗余负荷时考虑1,2个发动机就可以了。
5个发动机就听天由命了
特斯拉的盈利 会有更多的钱来支持spaceX 而后者的成功 就是连带着让特斯拉股票更高的商誉
我相信 特斯拉赚的钱是拿来个spaceX的 而星链是一个浪漫的自由的礼物而已
这不可能。 股东又不是傻子。
感觉应该不应该影响那么大， 只要不爆炸， 损失几个应该问题不大。 爆了， 就彻底玩完。
我现在不看好这个， 感觉太多垃圾在太空。
上个月NASA在火星上发现了可供人类生存的水量和痕迹 可以说明 要么火星上曾经有过生命 要么火星上已经有了生命
人类现在连自己居住的地球地核地层 到底是怎样 甚至连海洋只了解了3% 有什么理由断言一切只是美好的想象和愿望
现代物理量子力学的研究 又开始重新研读亚里士多德的著作 形而上学 论 现代物理又和古老哲学混在了一起
地球的环境已经越来越恶劣 人类如同蝗虫 把原本的生态平衡破坏了 这个行为还在加速
取决于马斯克的理想是什么：是资源掠夺还是星辰大海
他只想回到火星的家。
为啥是千分之一？有数据来源吗？为啥不能在未来是十万分之一，百万分之一？不能拍脑袋吧
不做功课就不要乱喷
35台发送机允许坏3台不影响发射。
如果单台发动机的失效率是1%，那么整个系统的失效率反而只有0.4%.
看你给一个什么时间段来参考了，
50年
100年
200年
所以他才有底气一天到晚叨叨叨怼天怼地，真是一天都不肯闭嘴的!
可能不是靠底气
而是 阿斯伯格
传记都有滤镜。不过成败论英雄，滤镜也不是啥问题
如果坏的发动机只是不工作，不影响其它发动机，那失效率应该是 0.04% ？
如果坏的发动机直接炸了，导致连环反应，那绑的越多越不安全
因为NASA想要美国有至少两个公司有独立发射载人航天的能力
我也很羡慕，投了几次连面试都没捞到。😭主要是我家附近opening不多。😭还的继续努力💪另外他家问预期工资就很讨厌😠
据说美国engineer毕业生，找工作，都是挤破头争SpaceX和Tesla？
Just read this, so fascinating

What is it like to work at SpaceX?
SpaceX has become quite a large organization over the last few years, yet it still maintains a startup mentality and feel to it. Despite its size there's a fairly flat organizational structure. For example, I reported to the CIO, which was only a couple levels down from Elon. I actually started out as an intern, and converted to full-time after a year of continuously extending the 3 month program. Even when I was an intern though, I felt like a full part of the company. If you do get hired on full-time, you will need to be approved by Gwynne and Elon; they used to actually interview everyone but the company has gotten too large for that. When I, and many of my coworkers, first got an offer from SpaceX, they paid to relocate us and set us up in some nice furnished corporate housing while we settled down and got to work. The factory itself isn't in a great neighborhood; you need a lot of space to build rockets and that doesn't come cheap in LA. It's located in Hawthorne, in between Inglewood and Compton. The neighborhood has gotten safer and nicer since we moved in, but we've had a stray bullet knock out a window before.
There are almost no private offices, as just about everyone has a cubicle, including Elon. You get pretty much full access to the factory, and can walk around and explore on your breaks. It's amazing to be able to see the process of building a rocket, basically from start to finish.

这叫冗余设计啊
这种发动机用来星际旅行没有希望啊。
不知道美国有没有研究更先进的发动机？

星链计划将4万颗卫星送上近地轨道，但每发射一颗星链，都会增加绕地球轨道运行物体的风险，在连锁反应下，太空将产生越来越多碎片和垃圾。
美国早就干过这种事了
美国西福特计划：向太空抛洒4.3亿枚铜针，多年后自食其果
https://zh.wikipedia.org/wiki/%E8%A5%BF%E7%A6%8F%E7%89%B9%E8%AE%A1%E5%88%92
西福特计划（Project West Ford），别名西福特针（Westford Needles）或针计划（Project Needles），是一个通过在以近地轨道上散布金属针形成云状环来反射无线电信号，从而解决当时美军在通信方面存在的重大弱点的计划。 计划概况[编辑] 背景[编辑] 在冷战时期，远距离的国际通信主要依靠海底电缆和自然存在的电离层反射无线电。美军对万一被当时的苏联切断其海底电缆后要依靠性质不稳定的电离层来联络其海外部队感到担忧，因而寻求能在全球范围内都可以稳定地以无线方式通讯的办法。 内容[编辑] 本计划打算将4亿3000万根[1] 铜制偶极天线（全长1.78厘米，直径25.4微米（1961年）/17.8微米（1963年）的针状物）[2][3]散布在轨道上形成云状环，然后通过设置在西福特镇的卫星天线作辅助远程通信。 美国军方委托麻省理工学院的林肯实验室实施计划。 实施与结果[编辑] 第一次散布于1961年10月21日，但并没有成功。[3]第二次散布则于1963年5月9日成功，在轨道上形成人工的环状针云并成功通信。[3]然而由于现代通信卫星的发展和遭到各界的抗议，本技术最终未能获得广泛运用。[4] 太空垃圾[编辑] 本计划散布的针状物分布于高度在3500公里到3800公里之间，轨道倾角在96度到87度之间的轨道范围，最终成为了太空垃圾[5] 。根据当时美国联合国大使阿德莱·史蒂文森的说法，在太阳辐射压力的作用下，这些针将会在短短3年内离开轨道。但事实上直到现在仍有相当数目的针残留在轨道上，[6] 偶然才会返回大气层[7]。 国际影响[编辑] 英国的无线电天文学者、光学天文学者与皇家天文学会抗议了此次事件。[8][9][10] 苏联的《真理报》也以“美国玷污了宇宙”为论点作出抗议。[11] 这次事件最终被提交到联合国[12]，并最后对1967年的外层空间条约所含条款造成了影响。[8]
肯定不是啊。这俩公司都是事儿多经常加班，然而钱不多，去的应该都是为了情怀和梦想。 也许intern是好地方。
