Is the FAA going to wait around till it does the same in flight?

I'm not so sure. The biggest explosion I saw in the video was right at the base. I think that the liquid methane spilled and fell to the ground. Probably the oxygen tank also burst by that time, spilling LOX right into the path of the

They're pitching something similar to the US military. The proposal is to use the Starship (the spacecraft alone without the Super Heavy booster) as a suborbital personnel/cargo carrier. Personally though, I'm a bit skeptical

These tests are applicable only to manufacturing or service-time defects. Pipelines can still break in the dynamic environment of spaceflight. Such problems are design problems, not manufacturing defects.

I see that comments mentioning the 'move fast and break stuff' philosophy are downvoted quickly here. While I don't have any direct knowledge of the Starship design and the SpaceX work culture, I do have years of experience i

In that image, you can see a white horizontal line on the heat shield, slightly below the point where the tank bursts. That was already there when the longer video clip starts. The tank later bursts along that line, even before the spilled

That's what it seems like to me too. From the slo-mo video, it looks like one of the propellant tanks (likely the methane tank on the top) burst open, spilled a lot of the propellant and then caught fire. Engines are unlikely to be the

The damage they do is much worse. They practically control the evolution of the web standards at this point, thanks to their market share. They also get to dictate the dominant standard and stifle competition in associated domains like imag

This is a chicken and egg problem. What is Mozilla's incentive in spending any effort on JPEG XL if Chrome doesn't support it? There won't be any demand for it from content creators until the majority browser adopts it. The o

It wasn't the lack of foresight that failed Wave. People recognized it as the base platform for a lot of future applications. They botched the rollout instead.

Strange! I was going to say the exact opposite. I find the near-white light from LEDs very harsh and tiring to my eyes. I often end up rubbing my eyes under them. The sodium orange feels cooler and easier. The strain on my eyes is similar t

It's not a clickbait. It's just a confusion caused by the missing context. The title might appear misleading on HN. But if you visit the Guix blog and see an article about Rust packaging, you will naturally assume that it's a

I'm not talking about your single comment. The entire problem here is the top comment and the peculiar responses to it. Many of your objections apply to that top level comment too. Yet you chose to reply only to people who objected to

There's no question that diseases like endometriosis and breast cancer needs to go. The medical research community is very self-critical about anti-female biases and there are numerous papers and articles about it. And that's good

Any reason to think that the ultimate effect of this fee hike won't be the increased cost of domain names? That too, more than 11% perhaps?

Org mode, especially org-roam is for stuff you need to forget, not remember. Org-roam's structured and interlinked information format allows them to be retrieved quickly on demand. A knowledge-base in essence. That frees up your memory

I assume that SpaceX doesn't want to completely shut off the Super Heavy engines during separation, in order to avoid the requirement of ullage thrusting for the boost back burn. But hot-staging is really hard on the equipment. It&#x27

That could very well be the case. I can't be certain. However, it's also a well-known problem in engine design. High flow rate fluid lines like propellant lines are often protected against fluid hammers. That may come in the form

One important additional detail is that the Starship started shedding debris (both inside and outside) and tumbling slowly, right after SECO. A leak also seems to have developed at the same time - which would explain the gradually worsening

The commentary gives me the impression that the booster didn't fail due to the reasons they were expecting it to. I think that they were expecting a successful engine relight and an eventual destruction due to loss of vehicle control.
