The Starship prototype blew up again. Musk: it's OK. We still have some

埃隆·马斯克在twitter上证实了sn11的爆炸。北京时间3月30日晚9时许，星舰原型机在10公里高度进行了第四次飞行，未能完成前辈们"解释"的任务，甚至没有走到Sn10以上。

Elon Musk confirmed the explosion of sn11 on twitter. At about 9:00 p.m. Beijing time on March 30, the Starship prototype made its fourth flight at 10 km level, which failed to complete the mission "explained" by the predecessors, and even went no further than Sn10.

美国东部时间3月30日上午8:00（北京时间下午8:00），博卡奇卡雾气弥漫。很多进入演播室的网友问："sn11，为什么我看不到？」

At 8:00 a.m. EDT on March 30 (8:00 p.m. Beijing time), Boca Chica was filled with fog. Many netizens who entered the studio asked, "sn11, why can't I see it? 」

网友们比伊隆·马斯克更焦虑。但是SpaceX也很瘦。

Netizens are more anxious than Elon Musk. But SpaceX is also very skinny.

3月17日，SpaceX在twitter上查看了Sn10测试视频。之后，美国航天局再次登陆月球的候选宇航员前往博卡奇卡，与星际飞船合影留念。

On March 17, SpaceX reviewed the Sn10 test video on twitter. After that, NASA's candidate astronauts for re landing on the moon went to Boca Chica and took photos with the Starship.

所以每次新闻发布，网友都会问，sn11什么时候能飞？几经耽搁，sn11终于在周二起飞。

So that every time news is released, netizens will ask, when can sn11 fly? After several delays, sn11 finally flew on Tuesday.

毕竟，有了"前三代"高空试飞的经验，加上Sn10的成功着陆，sn11的成功概率应该会大大提高。不料，sn11在起飞后5分49秒内"失去联系"。

After all, with the experience of the "first three generations" of high altitude flight test, and the successful landing of Sn10, the probability of sn11's success should be greatly improved. Unexpectedly, sn11 "lost contact" in 5 minutes and 49 seconds after takeoff.

现场录像暂停，摄像头信号丢失。之后，评论员约翰因斯普鲁克的声音从屏幕上传来，"sn11不会回来，不要等它落地。」

The live video was suspended and the camera signal was lost. After that, the voice of commentator John insprucker came from the screen, "sn11 won't come back, don't wait for it to land. 」

星际飞船又爆炸了

Starship blew up again

9点左右，sn11原型机引燃3架猛禽，从博卡奇卡起飞。

Around 9 o'clock, the prototype sn11 ignited three raptors and took off from Boca Chica.

5分钟后，当sn11距离地面约5公里时，一架外部机载摄像机也拍下了sn11拍打云层上方襟翼的照片。

Five minutes later, when sn11 was about five kilometers above the ground, an external airborne camera also took pictures of sn11 slapping flaps above the clouds.

5分35秒，2公里，5分45秒，1公里现场录像停顿，随后发生爆炸。然后约翰因斯普鲁克向所有的网友解释说，我们似乎又有了一个令人兴奋的测试。

Five minutes, 35 seconds, two kilometers, five minutes, 45 seconds, one kilometer The live footage came to a standstill, followed by an explosion. Then John insprucker explained to all the netizens that it seemed that we had another exciting test.

由于天气原因，sn11航班的最后一段没有被捕获。一位听众迈克尔·哈里斯说，爆炸的声音和气味给他留下了深刻的印象。杰西·科彭霍夫看到碎片从天而降。因此尚不清楚sn11是在着陆时坠毁，在空中爆炸，还是在飞机着陆前启动了飞行终止系统，从而摧毁了原型机。

Due to the weather, the last segment of sn11 flight was not captured. One audience member, Michael Harris, said he was impressed by the sound and smell of the explosion. Jessa koppenhofer saw the debris fall from the sky. So it's not clear whether sn11 crashed on landing, exploded in the air, or the flight termination system was activated before the aircraft landed, thus destroying the prototype.

但马斯克很乐观，"至少洞在正确的地方。但现在看来sn11并没有成功，因为爆炸意味着SpaceX失去了sn11测试的所有数据。

But musk is optimistic, "at least the hole is in the right place. But now it seems that sn11 is not successful, because the explosion means SpaceX lost all the data of sn11 test.

马斯克还在推特上稍微解释了爆炸原因。"看来第二台发动机升上去有问题，降下来重新点火时没有达到压力室，但理论上没有必要。"在重新点火过程中出现了一些重要问题。在检查了这些碎片之后，我们可以找出原因。」

Musk also slightly explained the cause of the explosion on twitter. "It seems that the second engine has a problem when it goes up, and it does not reach the pressure chamber when it goes down for re ignition, but in theory, it is unnecessary. "There were some important problems during the re ignition. After checking these fragments, we can find out why. 」

不过，这在马斯克眼里可能不是什么大问题。"高效的生产效率解决了许多问题。不出意外，sn15将在两天内送上发射台。

However, this may not be a big problem in Musk's eyes. "Efficient production efficiency solves many problems. No accident, sn15 will be sent to the launch pad in two days.

快速迭代不是玩笑

Fast iteration is not a joke

从2019年7月25日开始，在星际飞船20米的首次飞行试验之后。在不到两年的时间里，埃隆·马斯克的星际飞船原型已经迭代到了sn11。

From July 25, 2019, after starhopper's first flight test of 20 meters. In less than two years, Elon Musk's starship prototype has iterated to sn11.

看起来很多，但用网友的话说，"火箭是用来炸的"。」

It looks like a lot, but in the words of netizens, "Rockets are used to blow up.". 」

在此之前，MK1，SN1，sn3，Sn4，sn7，sn7.1，SN8，sn9，Sn10，SpaceX轰炸了9艘星际飞船。

Before that, MK1, SN1, sn3, Sn4, sn7, sn7.1, SN8, sn9, Sn10, SpaceX bombed nine starships.

星际飞船原型的失败有不同的原因。有的在飞行前因为压力试验而解体；有的在焊接工艺上失败；有的在地面保障设备（GSE）的快速断开功能上失败；有的为了测试油箱的压力极限而故意让其爆炸

There are different reasons for the failure of starship prototypes. Some of them disintegrated before flying because of the pressure test; some of them failed in welding technology; some of them failed in the quick disconnect function of ground support equipment (GSE); some of them deliberately let it explode in order to test the pressure limit of the fuel tank

然而，马斯克将"从失败中学习、快速修正、快速迭代"的优秀品质和方法论发挥到了极致。肉眼可见的原型测试速度正在加快。从去年一两个月的"爆料"到现在，Sn10上周刚刚爆料，sn11将于下周交付发射台。

However, musk has brought the excellent quality and methodology of "learning from failures, rapid correction, and rapid iteration" to the extreme. The speed of prototype testing visible to the naked eye is speeding up. From last year's "blow up" of one or two months to now, Sn10 has just been blown up last week, and sn11 will be delivered to the launch pad next week.

虽然SN8失败了，但马斯克给出了非常高的评价——SN8在飞行中几乎完成了所有预定目标，团队获得了所有需要的数据。这也是距离SN8 10公里的试飞。

Although SN8 failed, musk gave a very high evaluation - SN8 almost completed all the scheduled goals in flight, and the team got all the data needed. It's also a test flight of 10km from SN8.

SN8、sn9和Sn10在发射和返回初期进展顺利，但在最后着陆阶段爆炸。

SN8, sn9 and Sn10 went well in the early stage of launch and return, but exploded in the final landing stage.

其中，SN8存在的问题是甲烷高位罐压力不足，发动机未达到预期推力，SN8未能成功着陆。Sn9失败的原因是三只猛禽中的一只在从水平翻转到垂直翻转时没有重新点火，推力不够，导致垂直翻转失败。

Among them, the problem of SN8 is that the pressure of methane head tank is insufficient, the engine does not reach the expected thrust, and SN8 fails to land successfully. Sn9 failed because one of the three Raptors did not re ignite when it flipped from horizontal to vertical, and the thrust was not enough, which led to the failure of vertical flipping.

在Sn10，SpaceX优化了着陆过程，并重新点燃了三架猛禽，用于垂直翻转和着陆助推。然后，Sn10关闭了两个引擎，并保留了其中一个最好的引擎，直到它降落在地面上。虽然Sn10完成了着陆，但几分钟后爆炸了。

At Sn10, SpaceX optimized the landing process and re ignited three Raptors for vertical overturning and landing boost. Then, Sn10 shut down two engines and kept one of the best engines until it landed on the ground. Although Sn10 finished landing, it exploded a few minutes later.

后来马斯克说，Sn10的着陆非常僵硬，并不完全是软着陆。由于部分氦气是从头舱吸入的，发动机推力很低，10米/秒的高速撞击压碎了着陆腿和部分底边，这也是Sn10着陆时似乎有轻微倾斜的原因。一些着陆腿没有正确展开，剩下的几个承受着所有着陆冲击。

Later musk said that the landing of Sn10 was very stiff and not entirely a soft landing. As part of the helium is inhaled from the head tank, the engine thrust is low, and the high-speed impact of 10m / s crushed the landing legs and part of the bottom edge, which is also the reason why the landing of Sn10 seems to be slightly tilted. Some landing legs did not unfold correctly, and the remaining few bear all the landing impact.

在2020年初，马斯克曾说他想每周建造一艘星际飞船，然后每72小时建造一艘。关键是为星际飞船建造一条生产线。在经历了特斯拉的"生产地狱"之后，埃隆·马斯克想在德克萨斯州南部部署一个类似的系统。他坦率地说，"生产一种产品的难度至少是制造一件东西的10倍。"。」

At the beginning of 2020, musk once said that he wanted to build a star ship every week, and then faster, every 72 hours. The key is to build a production line for the Starship. After experiencing Tesla's "production hell", Elon Musk wanted to deploy a similar system in southern Texas. He said frankly that "it's at least 10 times more difficult to produce a product than to make a thing.". 」

不仅如此，不久前，一份关于在南得克萨斯州扩建发射基地的报告被公之于众。SpaceX计划未来在这里拥有两个轨道级发射器、两个亚轨道发射器、星际飞船和超重型试验站，为轨道飞行提供地面设施。入口处甚至还有一只星斗。

Not only that, not long ago, a report on the expansion of a launch base in South Texas was made public. SpaceX plans to have two orbital level launchers, two suborbital launchers, star ships and super heavy test stations here in the future to provide ground facilities to support orbital flight. There is even a starhopper at the entrance.

SpaceX甚至提议将博卡奇卡（即地面上的星舰试验场）改造成"21世纪的太空港和度假胜地"。

SpaceX even proposed to transform Boca Chica (that is, the star ship test site on the ground) into "21st century spaceport and resort".

这意味着它不仅仅是一个通往火星和太空的港口。它还计划在这个远离火星的地方建造一个度假村。这里有度假酒店、独木舟、派对和派对，在SpaceX的高湾顶部将有一个酒吧，可以俯瞰火箭工厂的360度全景。

It means it's not just a port to Mars and space. It is also planning to build a holiday village in this place away from Mars. There are resort hotels, canoes, parties and parties, and there will be a bar on the top of SpaceX's High Bay, overlooking a 360 degree panoramic view of the rocket factory.

随着去火星进程的加快，原有的博卡奇卡发射基地显然不够。但这个想法听起来有点离谱，但也是"埃隆·马斯克"。

With the accelerating process of going to Mars, the original Boca Chica launch base is obviously not enough. But this idea sounds a bit off the mark, but it's also "Elon Musk.".
