2. Loverro has made multiple statements (such as the one quoted by ncb1397) that point to a preference for a simpler SLS-launched architecture.

I'm confused.

And perhaps that it has some support inside NASA, which is also not surprising. The question is whether it has the right people supporting it inside NASA...This is an explicit change in plans. NASA would not be doing this if they hadn't already decided EUS would debut on an uncrewed flight. Nor would there be a need to retain Block 1 if not for a dual-stack-and-launch lander architecture (as ML-1 is only compatible with Block 1).

I never understood why debuting EUS with a crew was even an option. Didn't NASA learn anything from STS 1? Block 1 needs to fly until 1B has a test flight.

It is all about the "right" people supporting it inside US Congress....The next step, which in my opinion is less than a year away, is that US Congress, again under influence of the Boeing lobby, will force NASA to work EUS into the very center of return-to-the-Moon plans. Either by writing an integrated lander into law or writing the launching of the lander element on SLS into law (like how US Congress did with Europa Clipper).

The House already tried doing this late last year. But it's not possible to legislate to success with an underperforming contractor and poor technical solution on a tight timeline.

Wedding the HLS to the SLS is a mistake. Putting it on an expendable,$1.5-to-$2 billion per launch rocket is not sustainable.
I'm extremely confused about how SLS/EUS would work for HLS. As far as I understand SLS and EUS have been developed under a cost-plus format until now but the lander contract is fixed-price. Doesn't this mean that Boeing would have to build and launch the EUS and another SLS by itself based entirely on funds awarded for the lander?But if NASA employees are working on EUS and pad 39B how can they be part of the lander contract, would Boeing reimburse NASA for their work?If the launch tower needs upgrades for EUS shouldn't Boeing pay for it?
