Ah I thought you implied Falcon Heavy could do what SLS is doing, my error and I did say 2-3x when right now i am off by 0.3x until the block 1B launches. You are right 2 of the new RS-25s testing today haven’t flown before and use 3D printed parts along with parts that have flown on the Space shuttle, but it’s a little different than saying it doesn’t exist and they are completely hypothetical. Same goes for the SRBs. Two other conversations where folks didn’t understand NASA did try and see if Falcon Heavy could replace the SLS key payload to TLI needs several times, the last in 2018, and SpaceX said no and I may have crossed the threads in my head. Let’s hope HLS and the Starship booster and refueling will meet the SLS 1B on time how ever relatively hypothetical they are right now.

Reply to My Personal Story About Challenger by MoabEngineer

I happened to have been sent to the nurse's office with a fever while my class and most of the school watched on t.v. I was laying there in the quiet darkness when I heard the office ladies start gasping and talking in upset voices. One of them said loudly, "this is a national emergency!"

I just lay there thinking we were about to experience nuclear war. It was the saddest feeling. I was sad I wouldn't get to say goodbye to my mom or see my dog again. Someone finally came in to get me and I learned what had really happened. I remember we all cried. It was not what my scared child mind had thought was happening, but it was very very sad.

Now you’re creating a strawman. I never claimed that the Falcon Heavy was equivalent to Block I SLS. I disputed your claim that it had 3 times the payload.

RS-25E is a completely new assembly line using new production methods and new engine controllers (as the original RS-25 hasn’t been built in decades)

BOLE (the new SRBs) use completely different casings (composite) and a new propellant mixture.

EUS is net new (but will be introduced for Block IA). Heck the mobile launch platform needed for Block 1A and Block 2 is having substantial issues. The only thing common, is the core tanks and thrust structure
