Interesting, did not catch that

It's at 46:55 here: https://twitter.com/elonmusk/status/1725861547065684095 I took some screenshots: https://ibb.co/1GvddL5 https://ibb.co/28BSxwG https://ibb.co/KmccttG Could be a bird, but doesn't really look like it to me.

Just want to add another comment in here that there is no manual termination, they are using a fully automatic flight termination system.

Surely the final Starship carrying passengers will not have auto flight termination?

Surely it will, but prob only Elon and a couple others will know about it

Space Shuttle didn't have an escape system either; its total death toll was 14.

Absolute numbers don’t really mean much. More than 14 people have died since this test flight on American roads. Shuttle death rate was about 1 in 75, which is insanely high.

What are the units on 1 in 75? People? Missions?

To compare with other launch methods, you'd need to use the same metric.

IIRC, Soyuz is actually more deadly, but it's been some time since I've seen the stats. Both Soyuz and the Space Shuttle are by far the most deadly form of transportation.

Why do we need satellites and space to care about each other? I don’t need a massive satellite in space, I need somewhere to live. A massive satellite in space is not going to provide me a house. And it’s not gonna provide any time before my death. Which is being hind because I’m homeless. Which is being hasten because, I have no healthcare. Don’t you understand? You’re all surprised about my negative comments but I’…

Gps uses satellites, and basically the only high speed internet you can get without a house is starlink. Both get better with starship

Yea, I've not seen up close shots of the launch facility yet, but it looks like it's all still there without massive amounts of destruction either.

It's amazing what happens when you apply 60 year old solutions (water deluge).

There are obviously similarities, but there are also important differences between SpaceX's solution and a conventional water deluge system.

The primary purpose of the water here is not to dampen the sound/energy, but to cool the metal plate below the rocket.

Do you mean this was a launch failure or a test failure? It was obviously a launch failure, but even the most optimistic wouldn't have expected anything else. As for whether the test was a failure: since it successfully did a bunch of things that didn't work the last time, why would you say it's a failure? A failure would have been scattering the pad all over again, and not getting to stage sep. Or worse.

You have to define upfront what you want to get from a test. After that you go back and see if what you got is what you expected. Optimistic/Pessimistic does not really matter. By this criteria, I would say failure/partial failure or partial sucess. There is no way this was a success. Also, everyone can call this what they want. The thing that grinds my gears is not respecting that other people do have a different op…

Before the launch, on the stream, SpaceX were saying that getting through staging was their primary goal this time. Everything else was bonus. So clearly it was a success on the primary mission.

Pretty similar to how a lot of NASA's missions have requirements like lasting 90 days on Mars. If that is reached, the mission was a success, even though they obviously don't just stop having objectives after that.

Second stage lost, looks like the flight termination system did its job. Unknown as to why yet. Going to be very very interesting to see the data that's released from this as well as all the higher quality video/stills that surface.

AFTS activation indicates deviation from planned trajectory. It's unusual, being so late in the burn. Could be a guidance issue, but SpaceX should be pretty good at that by now. Could be engine underperformance, but we got nominal callouts and it would have to be pretty bad for AFTS to notice with minutes left, so that seems unlikely. I'd guess engine control (due to damage during staging) is the main suspect. We say…

I dunno, it looks like a nominal shutdown to me. The speed readout shows rapidly decreasing acceleration just as the engine displays go out instead of the telemetry suddenly going stale as you'd expect if it just blew up during the burn. Then, after the acceleration has gone to zero, the telemetry goes stale, so my guess would be on something going wrong during shutdown (ullage collapse when the propellant sloshes forward as the engines shut down maybe, this was a problem during the first landing test.)

AFTS seems unlikely this late in the burn, I think they said it was in terminal guidance and it's very hard to laterally change the impact point in any meaningful way with that much velocity. But I agree, it definitely looked like something's venting near the end, too.

To be fair, Apollo also had government funding to the tune of approximately 2.5% of GDP. Starship would probably go a bit faster too with an annual budget of half a trillion.

Perhaps, although not obvious that it's cash starved. NASA's slow but meticulous approach has had a few failures, but also incredible successes such as the sky crane martian rover landing - got to get it right first time, tough to move fast and break things when the test environment is 100 million miles away! Edit: Same goes for 1969's lunar lander - had to work first time.

And NASA can be fast too. If I recall the Genesis of the Voyager missions correctly, someone noticed the once in a lifetime opportunity where the planet would align properly for a probe to visit a lot of them in using clever gravity assists. And from there NASA acted quickly to get funding, design and launch 2 probes that are still active today!

Wow, really displaying your ignorance here lol The SpaceX flights are way more efficient and reproducible than the Apollo missions ever were. The only reason they aren't regularly going to the moon is that there isn't a strong incentive to do so.

You must be trolling.

Do you have any idea how many completely uneventful flights Falcon 9 vehicles have flown? The most recent version (the FT which had its first flight in 2015) has had precisely zero failures across 254 launches.

They have a better safety record than any other launch vehicle in history, including the Saturn V and the Shuttle.

The deaths stemming from those programs have held back interest in manned space exploration more than any failed test flight ever will.

SpaceX can reliably deliver payloads to orbit at much cheaper prices than anything before. The Moon program had its share of disasters, near-disasters and other failures (Apollo 1 burned with all its crew on the ground). Starship is a vehicle in development and will obviously have all sorts of bugs and edge cases to be worked out.

Don't post conspiracy theories that aren't even worth debunking here. In the same vein people are tired of debunking noahs ark, the young earth, the flat earth, and intelligent design. It's just tiresome at this juncture. It is a waste of everyone's time and if you insist on doing it you can do it on facebook instead.
