So if things go well and following the process of previous launches we should see a pressure test on the 28th, static just after new years, wet dress rehearsal between the 4th and 9th and finally a hop between the 11th and 17th correct?

They're taking the solid rocket motors designed for reuse and the shuttle engines designed for reuse and dump them in the ocean after each launch. The first few launches even have actual space shuttle engines on them that actually were recovered and refurbished multiple times before.
Instead of trying to improve on 70's technology slightly in order to make it viable, they just declared it all too hard. Then they proceded to spend 30 billion dollars trying to figure out how to downgrade 70s hardware in a way that it almost performs like 60s hardware.

>writers and artists of yesteryear: rockets need to be tough, so they're probably steel
>Old Space then: NONONO STEEL IS TOO HEAVY! We'll only use the most advanced materials who may be ill suited for the task, but we can use advanced science to make it work anyway, saving several grams on every flight for just a few billion dollars extra

>One Musky Boy recently: Hey, I'm new here. I'm gonna build rockets out of steel cause it's tough.
>OS: But you need to-
>OMB: Eh?
>OS: Advanced materials and -
>OMB: Huh?
>OS: YOU CAN'T JUST BUILD ROCKETS IN A SCRAPYARD IN A SWAMP!

Mars is just gonna pay for the mars colony out of his own pocket at this rate.

Looks like SN6 cryo was a success, might see another hop in a week or 2.

Heinleinism for Martian government. Do your duty for Mars. Service guarantees citizenship.

No says the man in Washington, you need to pay for cost-plus!
No says the man in the Vatican, you can't just leave this rock!
No says the man in Moscow, you need to pay bribes for 60 year old technology!
I rejected those answers. Instead, I chose something different. I chose the impossible. I chose:
Memelongrad.

God, SLS is such a joke.

not today

The grand Finale is coming faster than Expected.

>what are the problems plaguing the SLS program
1. Design concept
It's basicly stuck in the 1990-2000s in the basic design philiosphy
(expendable hydrolox lower stage with SRBs)
2. Production concept
Instead of beeing build by a single company, it involves a shitload of contractors, each producing administrative costs and wanting its own margins wich drives up prices and slows down development.
3. Sunk cost fallacy
Because absurd amounts of money have been sunk into SLS, people think it must produce results eventualy by dumping even more money into it.
That's a flawed assumption as it doesn't get you back anything of the wasted money, it just raises costs even further for a launch vehicle that when launched probably has higher marginal costs than what the competition offers launches for.
>and how do we realistically overcome them?
We would need to start from scratch again as the entire design and production philiosphy behind it are the main issue.

Are you a Boing employee being devoured by flames perhaps?

Looks like Elon is back to "Normal" but still I like him even when 420musk.exe is running and he even was watching the stream with he boys. Back to Business.

IT'S FUCKING HAPPENING!!!

>OK, /sfg/ how could you unfuck SLS and Artemis?

>Where do you even begin?

Like this.

HOLY SHIT GUYS, ELON FUCKING DID IT!!!
