np, I think there's a lot of misunderstanding of what they're trying to do, and how they're going about it. By no means am I saying they will be successful either, they got a lot of work still ahead of them and some very difficult problems.

I also hink this picture is a great picture as well that showcases it on just one part of the ship

Raptor 1: Works, may have been as far as NASA ever went for the entire moon project if they were in control.

Raptor 2: Okay we've figured out how to optimize some things, lets see how this works and get more data

Raptor 3: Okay we should be able to cost effectively mass produce this version after we work out the kinks. (edit: also the jump from 2 -> 3 was them doing 3d printing to make those tubes/channels in the structure to make it more reliable and easier to manufacture. It's not like all that plumbing wasn't needed)

Internet: They keep having engine problems, Starship is broken!

Edit: For reference, the RS-25 engine that SLS is using, and how the engine works is less complex than the Raptor engine which is the first ever flown full-flow staged-combustion rocket engine. The optimized v3 Raptor engine meanwhile has about 2.25x the thrust/weight capabilities
