SLS continues to backfire? You don't say...
I don't know how many would agree with me, but I feel like it's time for NASA to give up on SLS. There are commercial options that are cheaper and use modern hardware and also cost less per launch. I don't think anyone in the space community even cares about progress of SLS. SLS = The same old house with a new paint job. I think the only benefit is that it can lift more than Falcon Heavy. And I'm not even 100% sure that's correct.
Me thinks the best course of action for continued progress is to get rid of the joke called SLS and devote those funds and employees to building spacecraft, probes, satellites, landers, etc. Let SpaceX (Fuck ULA. It'd be nice to see companies that aren't "Boeing" or "Lockheed" get government contracts.) handle the launches. They've proven themselves capable. They can use the same rocket a few times. SLS? One and done, baby.
