Every time I see the this rocket, it reminds me of the scene from the Brady Bunch movie where Mike's latest design is just the same design as his house.

There's still a very real and distinct possibility that SS makes orbit before SLS/Orion.
Which is truly sad, all in all. |

Do I remember right that the tanks on the SLS can only be pressurized a set number of times before they get concerned about integrity?
I seem to remember that being a reason they did not do as many test loads of the tankage before the big show. |

IIRC they pressurized the LH2 tank to 260% of its maximum expected pressure before it popped. Don't know what that means for number of cycles but I'd bet it's still ok. |

More stuff than most people think in there. The Rock and Tilt thrust vector systems are in there so a couple APUs running hydraulic pumps, the whole hypers system and hydraulic system for those and some computers and both R&T actuators for the nozzle all inside and the 4 booster sep motors mounted on the outside. |

So do I understand this right.
Engineers close a valve on 2 of the 3 engines to raise pressure on that circuit, they the other engine's valve open, so they think there is a leak because the pressure is lower on that one engine compared to the other 2? Also, they reused a lot of stuff from other space programs? |

SLS can still only boost 23 tons into space while Apollo in the 1960's could boost 51 tons. Recycled R25's aren't going to get it done if you have to boost 10 times to the space station to drop shit off for ferrying to the moon later.

Quote HistoryQuoted: Is this bitch the heaviest lifter of all time? If it launches before starship it will have the most first stage thrust than any rocket ever. So most powerful rocket ever….until starship. Saturn V was built from the ground up to lift the most tonnage into orbit. So Saturn V could. Get 140tons to orbit. That’s probably more than SLS will ever get to orbit. Because SLS has inefficient underpowered upper stages to ‘save money.’ So SLS most to orbit? Nope. And never will be. Most powerful first stage? yes…….until starship. So it will be pretty metal to see it blast off and it is super historical. |

Supposedly, the Block Two slightly beats the Saturn V if you deduct the dry weights of both stages. I have heard the Apollo numbers tend to count the S-IVB dry mas and the SLS does not count the dry mass of the upper stage. |
