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

Quoted: And some of these parts, like the Orion, have been around since 2009 before Obama tanked the program. View Quote View All Quotes View All Quotes Quoted: Quoted: lolwut? Not sure if serious, or making a joke about the original intended launch date of 2016. And some of these parts, like the Orion, have been around since 2009 before Obama tanked the program.

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. |

Quoted: Ah. I didn't realize we were talking about a skirt (despite it being obvious). There's not much going on in that assembly, it's mainly structure. View Quote 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? |

The current plan is for Starship and NASA's hardware to work together to get to the moon.

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.

Quoted: Is this bitch the heaviest lifter of all time? View Quote 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. |
