So which one was it?

Shorter webm of just the moment of death

Starship cost-plus when

SLS is kill

>not a single engine failure in any Space Shuttle launch
>engine failure in a space shuttle flown engine during testing

the fuck? what are the odds

>>12590230
I bet 2060. Can we put a RIP 2060 memorial on the barrel section?

Doesnt it seem funny how every time NASA does a stream they have a memorium of some boomer from golden era NASA? They're dropping like flies lmao

>>12590230

This is the end of NASA

>>12590230

Man, this ain't good news for SLS, but the "orange rocket bad" crowd is REALLY reaching today.

>>12590260
It dent'nt

>>12590238
Pure coincidence.

>>12590260
It got better

>>12590230
Kinda hoping it was 2058, since that's the one I saw live before, though probably 2060

I just don't understand this reusable test stand meme.

The amount of money you can save from reusing test stands isn’t enough to justify how much harder it makes it to perform the difficult burns at usually make money in the testing world. I’m sure one day reusability will be more effective, but the truth is that when you have all the challenges that come with structural science in general, it’s almost always much more effective to throw away the stand after it’s done its job than to figure out how to make recovery part of the mission. I know of no major technology on the near term horizon that would change that.

Even if reusable test stands are possible now, but when reliability is THE number one priority (in this case the core stage takes up 2/3rds of the cost and the actual stand only 1/3rd) it makes absolutely no sense. Like, look at this test stand (pic related). This represents some of the most advanced technologies in the aerospace world. Do you honestly think that such a complicated machine can be made tough and reliable enough to be reusable? I doubt it. Best example in my opinion is condoms, sure you could reuse them but making sure that they do not suffer a drop in reliability will cost a lot of money and time.

Just because some country made reusing test stand popular, then that doesn't mean that we will have the sci-fi future of millions of rocket engine burns per year. We'll be lucky to see more than a couple dozen per year. Dial down your expectations, don't buy into the 'reusability for test stands' meme.

>>12590260
the dent popped back out on it's own

>what could have been

>>12590248
Pence did say to go to the moon by any means necessary. better dust of this proposal

>"They only used it once!"

>>12590263
I dunno if you actually watched but the presenter girl decided to just read her post-test script which included wonderful lines about how "now we get to put it on a barge and stack it at Kennedy!"

>That poor NASA engineer trying to explain that this was a good result through tears

Post test press conference ETA: 1 hour

This will be interesting, wonder how they will defend SLS now, if they will force through on time delivery or decide to redo the test

>>12590260
Someone blew down the top of it to make it pop out.

Based Elon playing 4D chess. Let SN9 dent right before NASA’s static fire and then let the problem fix itself while Boeing! fails miserably

>>12590282
Will Jim be there??

>>12590260
Blessed by starhopper. This is a good omen for the next hop, I'm sure

>>12590280
Yes she clearly read from the script where everything went right. Doesn't change the fact that they're not going to send it to KSC when they didn't get their TVC data. They can't pull a WDR here; this is going to need a redo.

>>12590238
could be a bunk sensor

>>12590247
>Sparks means engine rich, something inside of there ablated. My guess would be hydrogen embrittled leading edges of the turbomachinery blades, since poor Engine 4 has already been fired 6 times, twice more than is strictly speaking safe. If the blades had failed at the roots the engine would have exploded like a bomb, but if they failed at the tips those shreds of metal/composite could be what we're seeing fly out of the engine. No bell breach or seal failures because there were no jets of hot burning gas coming from places they shouldn't.

>>12590282
>even though the test was short we are confident that the performance of the other three engines are consistent enough to extrapolate for a full burn
>we will test the replacement engine separately before attaching it to the core
>afterwards Artemis 1 will be ready for launch soon(tm)

>>12590282
They'll redo. They aborted right as they were about to do gimbal tests, and without that gimbal data, there's no way they can stretch the test criteria to call it successful.

>>12590293
>this is going to need a redo.
Will it take longer to swap in all new engines or just one engine or refurb all of them or swap in engine or refurb or oror or

1) read through this September 2011 SLS overview
2) find something funny and post it here
https://www.nasa.gov/pdf/594163main_2011-SLS_Industry_Day_Final_Public1-1_rev2.pdf

>>12590293
Obviously, one of the engines is fucked. So they need to replace an engine. Which on SLS is a multi-year endeavor. Which means the SRBs will expire. Artemis 1 by 2024 now.

>>12590287
It looks like Aerojet-Rocketdyne screwed up instead of Boeing this time

>>12590296
Anon is an idiot. Look at Shuttle launch aborts. RS-25 ÷

>>12590303
depends on if the engines were fed properly. If you get some solid fuel in there or the wrong mix the engine isn't going to be happy

>>12590301

>Near-Term Capability
>• First flight in 2017

>>12590300
All four would take longer. Even just swapping one would be a pain in the ass.
Depending on the failure, a swap might not be neccessary. There's no evidence the engine was destroyed.

>Depending on the failure, a swap might not be neccessary. There's no evidence the engine was destroyed.

So we're all just memeing until the press conference

>>12590301
what could've been...

>>12590302
I don't get where this is coming from. The engine MAY be fucked. All we know is that there was component failure followed shortly by a redline and abort. PART of the engine is definitely fucked, but a full replacement isn't neccesarily going to happen.

>>12590301
what the FUCK

>>12590316
at this point, spacex can make starship out of liquorice and that would still be a better decision than what oldspace can do

>>12590319
Pretty much.
Full RS-25 swap is pretty much the nightmare scenario. Doable, but not fun.

No, they don't have to take it out of the stand for an engine swap, thankfully. They have equipment to do the change out on the stand itself.
It'd be several months for sure, but not a year.

I still say (slightly) turboblade rich exhaust, but if a fireball and white hot sparks is normal for RS25 shutdown then it might be something as relatively simple as some electrical component shitting the bed.

All the SLS engines underwent full-length static fires before they were integrated with the stage.

They've got a pretty good lock on the root cause now. Engine didn't eat itself.

>>12590475

Starship is still a hoax, on the level of Hyperloop. The recent stupid statements from Musk about catching the rocket with some types of hands only prove he is not serious. You all should stop celebrating 1 tin can hopping, since its not the real starship, it doesn't have a stage, it has less engines, its empty, it doesn't have a crew compartment, life support, navigation, energy, communication. The few hops of the tin can don't bring you closer to the CGI starship going to Mars, even if this would be possible with current speed Starship will not fly people to low Earth Orbit untill 2027.

true, because it's a structural and propulsion testbed
>The few hops of the tin can don't bring you closer to the CGI starship going to Mars
Wrong, it's a full scale second stage structural and propulsion testbed – something that can't be said for literally any other HLS proposal
>Starship will not fly people to low Earth Orbit untill 2027.

No, i am being optimistic by giving you even this close of a date. Playing with a testbed is fun, but the real spacecraft is not a testbed that you can lose and start from scratch, the real superheavy stage and starship will be expensive, long made and painfull to lose, years of setback.

>>12590649
If humans die on Starship, Elon can't just go out and say "Well, Space is hard, guys)))", when humans are on board its another game. And if Elon wants to make Starship carry 100 people, he has to create a life support system that never existed before. I'm not even sure you can put so many snacks and water bottles inside starship to feed 100 people on their way to Mars. Imagine if there is 1 and 2 toilets on Starship and both of them break during the trip to Mars - everyone dies in shit.

Elon is somehow going to put 100 people in space in one ship and somehow sustain them alive for a long trip to Mars? Not happening. You will see the slights goal post shifting to the point when Elon will say - we can transport maximum 10 people on Starship.

>>12590675
Nah the armchair engineers in here will tell you that the totally normal sparks on RS-25 shutdown means the engine ate itself and anyone telling you otherwise is just cope

>>12590668

Then don't fly 100 on one Starship. Simple

Hohohohooooly shit lmaooo

>>12590677
Dude, life support is a complicated thing, the more people you carry, more complicated it becomes. Every person is breathing, eating, sweating, drinking, wants to wash himself, wants to piss and shit. If you design a ship for 100 of people, its going to be a nightmare to make a life support system for them. I know its HARD for you to understand because in the mocies like Star Wars they have ships with 10000 of people on board and they have artificial gravity and they never mention how they all survive in space in such numbers on ships, but in real world, you need to solve the life support problem, and its hard, really hard. So far Elon never even acknowledged it as a problem. Hell, we haven't even seen solar batteries latest design or the communication array on Starship, we don't know if it will have an antena to speak to Earth.

I don't think even the most blind SpaceX fan boys still believe Starship will carry 100 people for Mars. Maybe 100 for LEO or E2E flights.

Ok, what about energy, docking, communication and airlocks for starships? Any info on those or any progress on those? Because this test stand hopping is not doing to adress these issues.

>>12590740
Things are easier when you have 100 tons of mass budget instead of filing down every rivet to save a gram. As I've already said and you've already ignored, the current test campaign is about testing the second stage structurally, testing the propulsion elements, and aerodynamic testing of the flip maneuver. SN15 will get a full heat shield for testing reentry.

Spacex has had a team of about 200-300 people working on this stuff for about 4 years, with the benefit of access to NASA's groundwork on planning out a mars trip over the past 40 years. you don't hear about it very much but it's absolutely happening.

There is also a refueling problem in space which has not been tested and it requires a lot of back to back launches of Starships with an insane efficiency, like when Starship going to orbit then the Starhsip tanker goes up that same day and refuels it and then another tanker the next day, and another one the next day, and another one the next day and another one the next day...And for Mars trip you need like 10 of these tankers? Were there any Falcon 9 10-in a row streak-series of launches separated by a day? So Starship also has to learn to do this before they go to Mars. How many years it would take untill they learn to do this?

>>12590750
>non-issue even for boeing
Didn't Starliner lose connection to the TDRS satellites during it's test flight, tho?

Fuel the rocket and launch it? They just need more rockets and places to launch them from, then press the button and let the mission run itself.

>docking
Reuse the Dragon docking port.
>communication
Nobody has issues with this as far as I know.
>Airlocks
Make an entire deck the depressurization area, use dragon capsule doors for humans and build a bigger version for the cable lift.

>>12590769
Refueling is the one that will likely be tricky. I don't think it's going to be IMPOSSIBLE, per se, but to my knowledge it hasn't really been done aside from a few propellant transfers on the ISS. It makes it a lot harder when there isn't old data to look at.

Also I remember a few anons telling me they plan on transferring the fuel directly through the engine bells. Was this just a shitpost or is that the actual plan?

With methane? 10 Soyuz launches back to back in 10 days? Because Starship needs to do exactly this.

>>12590781
dude, they delay even the simple falcon 9 missions because a cloud on the horizon, you want to convince me they are going to rapid shoot 10 starship launches, landings and refuelings in 10 days. It sounds unplausible in a short term. More like they are going to make 1 Starship, give it a name and then be very carefull with this 1 Unique Starship with the name, with every launch being separated from the next launch by a year or two and then they are going to make the Starship tanker for another 4 years.

No, those sparks were from the same sparklers that you see going off before ignition. They're just there to let any stray hydrogen burn off

>>12590822
1 tanker is not enough though, even for the Moon trip. The tanker itself eats a lot of fuel to get the fuel as cargo to orbit.
Starship without refueling can't even leave LEO.

The wider the grin the bigger the lies.

Man, I will never like SLS... but Big Jim is such a lovely person that he could probably make Challenger and Columbia seem like successes.

isn't jim right, though? Those SRBs are serious. I thought that 2 giant SRBs + 4 RS-25s > Saturn V's 1st stage thrust. It's not the best comparison due to staging differences but still.

>How many launchpads they need?
if they can launch depots at their leisure not many. The entire point to this approach is that is makes cadence demands far more lax
>How long they will stay in orbit untill LOX boil off will happen?
methane != hydrogen. You can prevent boil-off. Even with hydrogen there are ways to prevent that

The Saturn/Apollo folks are long gone and most of the Shuttle people are either gone or mentally checked out. This is a new generation of engineers and workers trying to figure out technology that their betters left behind for them. NASA has too many priorities other than ability when it comes to staffing and that's starting to really pay negative dividends.
