re: NASA pushes back dates for Artemis II and Artemis III missions.

There is so much incorrect information in this thread I don't know where to begin, but let's start with the OP.
This was specifically addressed in today's press conference. While it's true that both Artemis II and Artemis III are delayed, one of the questions that was asked was, "If Artemis II had not been delayed, would Artemis III have been delayed anyway?" The answer provided by NASA reps was "yes, due to Starship delays" and the SpaceX rep on the line confirmed it.
What? The RS25 is one of the most amazing machines ever built by man, and is still unrivaled in terms of its combination of both thrust and specific impulse.
This isn't true. The 3 reasons for the Artemis II delay were all mentioned in today's press conference. All 3 issues belong to Orion. They were 1) an issue with the Orion heat shield discovered after Artemis I, 2) an issue qualifying an upgraded Orion battery design from what flew on Artemis I, and 3) a design issue discovered on Orion life support systems (which weren't installed on Artemis I.
The Smarter Every Day video posted above is a good watch and points out legitimate issues with the Artemis Program. Every issue he points out are related to limitations of Orion, and the most convoluted con-ops man has ever conceived in Starship. 15-ish (nobody knows how many) launches in 20 weeks with 14 in-space refuelings to bring a ham sandwich to the moon...

Artemis II was supposed to have taken place later this year. The delay of Artemis II now pushes back the date of Artemis III.

For this flight, SLS is behind on the construction and certification of the vehicle.

I think you're going to see Starship make some big strides this year and my bet is that it won't be the limiting factor after another year of testing is done. The SLS is an impressive machine but it can't really do anything other send the Orion to lunar orbit. Starship will be doing all of the heavy lifting for the Artemis program and I think eventually the SLS will be retired and it will be SpaceX show. Hopefully Blue Origin will get its act together and get New Glenn of the ground this year so they can have a piece of the pie.
The name of the game in the space industry now is reusability and so far SpaceX are really the only ones doing it. I'm excited to see what Stoke Space can do as well. They have an interesting design.
