NASA chief suggests SpaceX may be booted from moon mission

Oh yeah. Replace the stainless steel by carbon fibre, give it to your pals of Boing and instead of being ready in 2030 for 2.3 billion it will be ready in 2050 for 50 billion.

Much better for making your friends rich.

Space X isn't much better. Its still Musks company.

So, the company gets things done but the CEO is unpopular with certain crowds. Seems better than Boeing, which is bad at getting things done. At least their CEO is inoffensive, and that’s what is important?

They haven't gotten anything done in regards to HLS. They can build their HLS and even launch it into orbit next year but then what?

HLS requires on-orbit refueling. Anything from 10 to 20 refueling launches will be required. Did you think it required one refueling launch? The SH+SS stack will never be reusable or reliable enough to accomplish the refueling operation in time and on budget.

This means one moon mission will require the use of 10 launch pads and probably 20 complete stacks to even be feasible, because reuse will not help one iota.

Their upper stage reuse will never pan out. Sure they will catch a few, then they will remove the engines and stick the rest in a shredder for scraps to be melted down and recycled.

Elon's HLS is completely detached from reality. I won't even call it a SpaceX system because it's unlikely anyone but Elon came up with it.

The refueling ships are to be launched weeks/months in advance, one at a time. If you look at the rate of Falcon launches this is nothing out of the ordinary.
