The best learning is done from failure. If it wasn't so ridiculously expensive to build rockets, pushing unmanned tests beyond the limits of the machine would be the very best method of improving its design. After all, you can't really know for sure how something will fail, until you see it fail.

You do realise that a 'failure' is actually a success when designing and engineering something, right? It means that you have data to work with. The SN8 was their closest perfect launch yet. The data they get from each 'failure' pretty much means that by the time people are allowed on board, there will be no need for an abort system as every single kink will be ironed out. They're nowhere near to a '1.0' launch. Each launch is to test a certain aspect of the design and anything that they can also test during the main test is a bonus. They're collecting mathematics and physics data. Why do you think crash tests for cars are a thing? If a car has no faults during testing then there's something that they've severely missed. The same goes for anything that is designed and engineered for consumer use.

Cannot the top half, second stage, act as an abort system, for boost phase. Lighting off engines while still attached to booster could be rather exciting, I suppose, as booster top dome takes a hit. Perhaps a bit of heat protection/blast deflector on dome and an open lattice skirt around top of booster to let exhaust gases out. Software to escape from any angle of booster, fly upper stage to gain sufficient altitude and burn/jettison fuel, to where a descent back to landing pad, or a water, can happen. Could second stage can hover above just a few feet above surface of water for an emergency landing, then shut down and let second stage drop, vertically into the ocean, while tipping over onto its side and float there. Figure out a way to perform a modified stage separation, fly up and away and descend back to a landing.

You sound like the same engineers who constructed the "Titanic" Should we add the safety? What are the chances? What are the statistics? Statistics have nothing to do with the killing of one life because one life is worth as much as a million lives. If you can not understand that, then you lack compassion and understanding.
Malachi Wiens
Malachi Wiens Pirms 15 dienām
The difference with the Titanic is that it failed on its very first trip. Everyday Astronaut is suggesting Starships should be flown and reflown to test their reliability and identify design flaws. I think if the Titanic was tested numerous times, enough to gather data and identify points of failure, then the design flaw(s) would have likely been resolved before putting crew on board. That's just my take on it, though.

Gippo50 Pirms 22 dienām
The big difference with Starship is it is completely reliant on its propulsive landing system. Or more specifically relying on two of two raptor engines relighting exactly when needed during the decent, no time to deploy redundancy measures at that point. This has to be much more risky than the Shuttles, Dragons or even Saturn V's re-entry strategy. Some degree of fail space would absolutely be worth it (especially even this is designed to be the first mass transit spacecraft for humans). Be that keeping all three engines lit during decent and only throttling up those needed for the actual landing manouver or just using (BIG) parachutes . . .
Tony Orabona
Tony Orabona Pirms 23 dienām
I was wondering 3 engines and 1 engine failure 33% of thrust lost ; combined with a risky late retro rocket start; resulted in this crash. But if we had 6 engines working in in a ring. Well If 1/6 engines fails only 17% thrust lost ; there should be enough thrust to land safely. Also we should start retro thrust earlier for more response time to correct for such failures. Well Elon What say you . Ok sure more moving parts more expensive rockets however your Cosmonauts might appreciate the extra padding ;) . And you might save money on fewer rocket ships Lost :(.

Considering the last two landings, maybe they need to look at aborting landings.

@Andrew York there are two types of test flights: 1) To show to everyone that i have done working rocket (this should be counted) 2) To test some ideas. This can't be counted, becouse they are not meant to be successful. They are meant as quick way to find where is current weakest point (looks like it's Raptor, not the manouver)
Andrew York

@Adam Řežábek it's completely fair to count test flights. They show that the current plan doesn't work.

You can't deactivate them because the chemical reaction is so quick and powerful. They are good but only as boosters or launch abort system because you can't control them. They are also cheap and have good P/W ratio.

@Ja Gil Falcon 9 us not that reliable. It has around 100 flights, and expirienced couple failures. So it's reliability is surely bellow 99%. Also, crew dragon has not been much proven. Starship will be proven by cargo mission, becouse it's second stage and a spacecraft simultaneously
Ja Gil
Ja Gil Pirms 23 dienām
@Adam Řežábek we've already seen this with crew dragon, they did not ditched parachutes for propulsive landing. And they kept the launch abort even though falcon 9 has been proven to be reliable. NASA loves extra safety and redundancy. Spacex care more about costs and payload, I think the sweet spot is somewhere in between
Adam Řežábek
Adam Řežábek Pirms 23 dienām
@Ja Gil will see. NASA has certain threshold for reliability. I don't think they care if it is achived by abort system or by reliable and proven vehicle
Ja Gil
Ja Gil Pirms 23 dienām
​@Adam Řežábek yep and as they planned to build and reuse hundreds of them there will be accidents. Murphy's law. NASA won't let this happen anytime soon if landing problem = death

It's actually a pretty good argument to have a robotic astronaut for the first few trials out in space; if you want to have something that can report what went wrong, it would be best done with a test dummy with redundant records all over it's body, than rely on an astronaut to come back in a complete body.

Why don't traditional air craft have abort systems. Because, 1 reason,. It's reusable & for the most part carrying extra weight 98% of the time & not use it sounds follish. But still good to have in the future when cost go down. But for air planes, we been should of had that system.

If there's anything we should have learned from the Columbia disaster, Challenger disaster... Every airline crash in history... the Titanic, it's that it doesn't matter how fail-proof we think it is, unless it's 100% reliable, there *WILL* be failures eventually. If SpaceX starts launching dozens of people on starships, without any escape system, then the Shuttle disasters happened for nothing.

Helicopters use propulsive landing, and that has worked out. (Of course they can usually land via autorotation if the engine fails). The Russians likely had a few more fatal flights that have officially kept secret, but some details of which have been leaked.

There's also the fact that they want the starship to be able to carry a lot of people. 100 people was cited at a time, but i don't know if that number is still on the table. Even if there are 50 people on board, that would be a very large abort module, big rockets and lots of fuel. But i don't think that they will be allowed to carry anywhere near that many people until it's proven to be extremely safe, so it could have some kind of smaller abort system for fewer people until it reaches that kind of reliability.
