Preliminary indication is that we had an oxygen/fuel leak in the cavity above the ship engine firewall that was large enough to build pressure in excess of the vent capacity.

Apart from obviously double-checking for leaks, we will add fire suppression to that volume and probably increase vent area. Nothing so far suggests pushing next launch past next month.

Test flights.

My tests keep failing until I fix all of my code, then we deploy to production. If code fails in production than that's a problem.

We could say that rockets are not code. A test run of a Spaceship surely cost much more than a test run of any software on my laptop but tests are still tests. They are very likely to fail and there are things to learn from their failures.

Even NASA years into their existence has suffered catastrophic fatal failures. Even with the best and most knowledgeable experts working on it we are ultimately still in the infancy of space flight. Just like airlines every incident we try and understand the cause and prevent it from happening again. Lastly what they are doing is incredibly difficult with probably thousands of things that could go wrong. I think they are doing an amazing job and hope one day, even if I miss it, that space flight becomes acceptable to all who wish to go to space.
loading story #42735989
Can you name a space company with less failures? Also I think it is unfair to even compare SpaceX to anything else, because of the insane amount of starts / tests combined unparalleled creativity.

According to this website their current success rate is 99,18%. That's a good number I guess? Considering other companies did not even land their stages for years.

https://spaceinsider.tech/2024/07/31/ula-vs-spacex/#:~:text=....

Success rate isn’t a great metric for efficient initial work: it will keep improving as more launches are done, regardless of the initial work.
loading story #42735556
It says right there in your source that that figure refers to Falcon in particular. For comparison, Starship's current track record is 3/7 launch failures (+1 landing failure).

There's an order of magnitude difference between them. If they were cars, it'd be like comparing the smallest car you can think of vs one of the biggest tanks ever made.

I ignored those, since the starship at this stage can be considered a prototype. I am just trying to argue, that calling SpaceX unreliable, especially compared to its competitors and time to market, is bold.

It sounds like he's talking to investors and not to general public.

In my experience in corporate america you communicate efficiency by proclaiming a checklist of things to do - plausible, but not necessarily accurate things - and then let engineers figure it out.

Nobody cares of the original checklist as long as the problem gets resolved. It's weird but it seems very hard to utter statement "I don't have specific answers but we have very capable engineers, I'm sure they will figure it out". It's always better to say (from the top of your head) "To resolve A, we will do X,Y and Z!". Then when A get's resolved, everyone praises the effort. Then when they query what actually was done it's "well we found out in fact what were amiss were I, J K".

It’s crazy how fast that ship is moving and how big the explosion was that it looks like something much, much lower in the air went boom. It was transitting the sky faster than a commercial aircraft does. So it gives an impression more like a private aircraft breaking up at 5-10k feet.
The last one is stage separation, not an explosion. You can clearly see the "exploded" rocket continuing to fly afterwards.

Where can I find the heat tiles? Will they be landing near Puerto Rico?
Another failure, another few months of figuring out why this isn't working and can't stick to its flight path. They caused chaos for many commercial planes, so they'll definitely need some full reports to the FTA to know what they're doing about this, why the debris is falling over flight paths, and so on.

First Shuttle orbited astronauts and successfully recovered all intended components. Every Saturn 5 was successful, the 3rd flight sent a crew to lunar orbit, and the 6th put a crew on the moon.

To date a Starship has yet to be recovered after flight - and those launched are effectively boilerplate as they have carried no cargo (other than a banana) and have none of the systems in place to support a crew.

Some people are really fetishizing iterative failure - but just because you are wandering in the desert does not mean there is a promised land.

This is irrelevant, as none of the flights included any plans to recover the Starship. The objective for each flight has been to dump the vehicle in the sea at the target zone.

That "landing" (is it still considered a landing if it's chopsticked a few meters before it touches the ground?) is so unnatural it almost looks fake. So big and unimaginable that it feels like watching fx on a movie!

Oh no they lost the ship after the booster landed! Seems like they lost an engine, then I saw fire around the rear flap hinges in the last images before they cut out, and then the telemetry showed more engines shutting down until it froze.

During ascent I also noticed a panel near the front fins that seemed to be loose and flapping. Probably not related but who knows.

Back a few years ago. This was the starship that in 2024 would reach Mars with humans, with so much space taken by crew and materials, and almost no fuel, and "10 times cheaper". And currently is an empty shell. Nice fireworks and show, but no meaningful payload yet. Not even LO. And this will be ready for 2026 artemis mission?

This is version 2 of Starship, with some upgrades, such as longer starship.

"Upgrades include a redesigned upper-stage propulsion system that can carry 25 per cent more propellant, along with slimmer, repositioned forward flaps to reduce exposure to heat during re-entry.

For the first time, Starship will deploy 10 Starlink simulators" [1].

Will be interesting to hear the postmortem on the second stage. The booster part seemed to work pretty flawlessly with the exception of a non-firing engine on boost back which then did fire during the landing burn.

If the person doing their on-screen graphics is reading this, I wonder if you have considered showing tank LOX/CH4 remaining as a log graph. I believe it decreases logrithmically when being used (well it would if you keep 'thrust' constant) so that would create a linear sweep to the 'fuel level' status.

What worries me about space innovation is the fact that there is such little margin for error. Materials are being stressed so much while trying to defy the laws of physics that the smallest angle error, the smallest pressure mismatch, smallest timing error, and boom. This did not happen when we were inventing cars, trains and air planes. Now imagine these risks, while you're halfway to mars. Is it possible that we just have no found/invented the right materials or the right fuel/propulsion mechanism to de-risk this, and that is where we should be allocating a lot more resources?

Can someone please please PLEASE tell SpaceX PR/Streaming team that the speed (per SI system) is measured in meters per second, not kilometers per hour? The speed of sound is approx 300 m/s, orbital velocity is approx 8,0000 m/s (depending on altitude), free fall acceleration on Earth is 9.81m/s, 1.63m/s on the Moon, the speed of light is apporx 300,000,000 m/s, people learn these numbers in middle school. It's not 1000 km/h, or 28,000 km/h, it just looks so weird.

That was so impressive. I was lucky enough to live in Florida and see the rockets go up. Standing on the beach and watching the first Falcon Heavy launch will be something that will always stick with me. Great job SpaceX.
It is amazing to see the number of fairly significant changes they tested in this launch. I guess that is the advantage of private space flights and rocket launches where the speed of development is must faster than in a place like Nasa or any government run space program.

I am not surprised that stage 2 failed because they were testing with a lot of the thermal tiles removed.

SpaceX started Starship development in 2012. Despite 12 years of work, its best test flight reached space but not orbit, sending a banana to the Indian Ocean.

While NASA's SLS began in 2011 and successfully flew around the Moon in 2022.

Blue Origin's New Glenn also started development in 2012 and reached orbit on it's first flight with an actual payload.

When they say SpaceX is fast, what do they mean exactly?

It seems like they have the chopsticks catch down pretty well, but the ship exploded over the Atlantic so there's gonna have to be more tests before the ship can think about an RTLS test.

More generally, getting the ship to work reusably seems like it will be a considerably greater challenge than reusing the boosters.

We are just one more lander / sample mission / whatever away from having solid proof of life elsewhere in the solar system. That is gonna jumpstart all a huge race to get humans out into deep space to check it all out.

People worry about AI stealing their jobs… don’t worry. We need that stuff so humans can focus on the next phase of our history… becoming interplanetary. Your kids will be traveling to space and these (very overhyped, don’t get me wrong) LLM’s will be needed for all kinds of tasks.
