There is supposed to be a post test presser.
NASA live says TBD and aprox 2hr after test and 7:30 so who knows when really. |

So....
Are those engines cooled with liquid helium? Liquid nitrogen? They froze over PDQ once the test fire stopped. No wonder the Shuttle was so frigging expensive to fly. Rebuilding those engines? Liquid helium taps into the zero point energy field. So, if that is liquid helium and we are inducing quantum realm fluctuations to the equation... |

NASA is to be congratulated.
They've now created a rocket so expensive that nobody can afford to launch it. If you launch that thing more that once a year it hollows out NASA's budget from the inside out. I doubt there's another space agency on the planet that could accomplish that. |

If you guys saw how ridiculously old and shitty and analog the aerojet/rockeydyne section of the HWIL was for SLS some of you would shit yourselves. At least the ones that have been in aerospace long enough lol.
I'm still amazed they let me do firmware loads/changes into the core stage flight computers when I didn't even know how to program in XML before I got into that lab. That was a couple jobs ago now thank god. Those poor test engineers back at MSFC are gonna have the saddles tightened as they run through that run a few more times on ARTEMIS/MAESTRO and analyze the existing data. That lab was some of the coolest and most complicated hardware I ever got to work on in the most absofuckinglutely pants on head retarded management and leadership environment. |

Quoted: I am certain my wife and I will fly down for the SLS launch. Watching that launch is probably going to be like watching a Saturn V. ... although based on this test, we should probably schedule a couple of extra days after the scheduled launch day. View Quote I have done a fair amount of work on SLS and CCV. I have been planning to watch an SLS launch in person. But I think the chances of Biden cancelling the whole thing are far better than my ever seeing a launch. |

Your endless SpaceX hate is all the more laughable when, once again, SLS demonstrates the utter failure of oldspace to accomplish even the old and routine. Another green run *might* happen in two or three more months. SpaceX is managing to swap out engines and relight within two to three days, while bitching that they're still striving to get that down to hours. Hell, the extra development costs from the delay caused by today's failure, are likely to be roughly comparable to the ENTIRE cost to develop Falcon Heavy. The latter cost $0.5 billion to create, while so far SLS has cost at least $11.5 billion...and hasn't even managed a successful test firing. And for what? $150 million can get you a Falcon Heavy expended launch ordered up and delivered within a few months, delivering 70 tons to LEO. So $2.14 mil per ton of payload. In another year..or two...Block 1 may finally fly..and carry 95 tons to orbit. At an incremental unit cost of over $2 billion...or in other words, $21.05 mil per ton of payload...literally ten times more expensive. You could literally launch half a dozen Falcon Heavys in expendable configuration, and pay someone half a billion to develop and build an orbital depot for your payload, and still come out hundreds of millions of dollars cheaper than a single SLS launch, despite putting more than three times as much equipment into orbit. And that's assuming, of course, that SLS continues to fly for decades, and the total development cost is amortized down to nothing. It's far more likely that Biden cancels the program, or it gets shut down by Congress in the next few years after a major failure. |

Watching the SN8 test flight I had the overarching feeling, right up until the last few seconds. That everything about this design just looked right. Watching this burn, when the propellant stopped flowing and everything froze over. All I could think was. "Oh ye gods, that must be a horrific strain on those components." Going from insanely hot to insanely cold in a couple heartbeats. Obviously methane and hydrogen are very different rocket fuels. But with currently available technologies. Methane and Kerosene seems like they are less of a strain on materials than having to deal with cryogenically cold liquid hydrogen. Methane and Kerosene propulsion seem like the immediate future of space travel. A possible... Blue collar approach. Using hydrogen seems like it requires the kind of care, resources and technical know how of a science experiment. |

View Quote the sls is a system designed around one engine, you cant just change it to another. A new engine would be starting over. which, with the whole SLS being pointless with musks Starship existing is a waste of money. Starship would be 10x-20 times cheaper to orbit WITHOUT BEING landed. Its target launch cost is aimed at being 1000 times cheaper then SLS, which even if off by 10X will be 100 times cheaper. |

Those 4 engines have flown cumulatively 25x's plus testing during shuttle program plus testing with new computers during this program in the test stand.
What has changed here? They are integrated with core stage now. It's fuel and control is from the core stage. The mission profile entered into the computer was specifically made for the green run. It more than likely had limitations set that would shut down or safe all 4 with any fault no matter what since this was a test with actual flight vehicle rather than a mockup or test stand. Even if it was something that an actual flight profile wouldn't consider shutting down the offending unit for. |

View Quote It's getting very hard to justify that when SpaceX is the one doing shit and everybody else is either dragging things out or fucking up. The big boys try to deflect onto SpaceX because they - the big defense players - are in bed with the politicians, and have been for a long time. They don't like that an upstart has come along that actually wants to get shit done rather than milk customers for all that they possibly can. SpaceX is poised to be the one launching the majority of stuff to orbit for the entire world. As already posted previously, they were >40% of tonnage to orbit last year. It won't be long before they are >50%. All the while doing it cheaper than everybody else, too. It gets really hard to justify why you need extra scrutiny on them while the big boys more or less get a pass when they are, in actuality, the ones dominating the field. |
