So is the issue a single thing or overall "everything is behind" deal? Is there a smoking gun or was the time frame too tough for 2024?
And dont tell me the issue is that we need to train a woman and person of color

The issues are the main engines and the technology behind them. They are still using SSMEs (Space Shuttle Main Engines) to power SLS. Once they run out of those they have to redesign or purchase them. Then they have to be certified for man rated spaceflight. The avionics and other systems are archaic at best. There are over 70,000 failure modes. Literally if printed all the failure modes off and stacked the reams of paper it would be half the height (212 ft) of the full stack. It's at least the height of the core stage. Then add to the fact the valves and other systems have to either be (a) sole sourced from a single vendor or (b) have to sit on a self and have a shelf life for the life of the vehicle....it's a poor way to run a space vehicle management.

For this flight, SLS is behind on the construction and certification of the vehicle. They wanted to get away from the ICPS (Interim Cryo Prop System) second stage but that fell through and they had to use another ICPS that ULA designed/built. They are gonna run out of those engines/modules QUICKLY. Next SLS have different upper stages and those all have to be certified. Heck the only common parts are the core stage and the SRBs. Above that it gets different for man vs cargo module.

The issue is that the program is funded and managed by people who think "woman and person of color" is at least equally important as and probably more important than "building functioning spacecraft on schedule."
