Tim Dodd just released an excellent (and long) video comparing the costs of SLS with Falcon Heavy and (eventually, maybe) Starship. https://www.youtube.com/watch?v=KA69Oh3_obY&feature=youtu.be

SLS will cost upwards of a billion per launch. Compare that to $90 million for a reusable Falcon Heavy launch or ~$150 million for a disposable one.

I feel like we'd all be better off if the federal government just cut an equivalent no-strings-attached check to Alabama in perpetuity, cancelled the SLS, and freed up all the rocket scientists to build something useful.

They could probably even do it in Alabama! SpaceX could open a local branch and mop up the talent. The current "waste money on the SLS for political reasons" just feels like the worst of all possible worlds.

Compared to $1m for a reusable Raptor that has more power at sea level.

There really should be painful monetary and career consequences for the people who makes these insane decisions. The reality is it doesn't matter a bit and they'll retire with a wall full of accolades.

Space isn’t easy. Going to the moon is significantly harder than LEO. I don’t think one can claim functional and performance equivalence between SLS to FH.

Now, if the argument is: Why go to the moon? Well, that’s a different conversation.

I don't understand - what is the motivation here? The article is a little short, and it gives good insight into just how expensive this is (compared to other similarly classed potential space purchases). However, what I am failing to grasp is... why? Why spend so much when these other options are available? Surely not ignorance. Is it malice? corruption? Someone's ego?

Last sentence: Politics.

You just assume that there are other options that meet their requirements, which might not be the case

This is a jobs program which happens to produce rockets. The rockets are not the key objective, the jobs are.

The requirements were made so that the SLS would be the only thing that would be rated to launch it
