The RFI released in October 2021 highlighted NASA’s commitment to America’s investment in SLS as a National Asset when it specified that NASA was not soliciting information on alternatives to SLS major hardware elements or alternate architectures other than those already planned by NASA. Any source capable of fulfilling NASA’s requirement must be able to assume not only the provision of new hardware, but also the integration of existing SLS hardware and design. NASA’s analysis of RFI responses revealed that DST is the only source capable of fulfilling the unique and highly specialized EPOC requirements. NASA will continue to examine the market for alternative solutions or new sources before executing any subsequent acquisitions or exercising any options for the same requirements. Establishment of EPOC launch services is anticipated to be a predecessor to future commercialization of such services. As commercialization of space capabilities and products continues to develop, it is anticipated EPOC will contribute to commercialization of the heavy lift launch market and thus commercial industry expansion will create robust competition in the future.
We don't disagree as much as you think we do. I just acknowledge that SLS is a political reality. I would prefer a commercial HLV but I don't expect that it will happen any time soon. The best case scenario from a political point of view would be to have a commercial HLV in addition to SLS in order to be able to have 2 crewed lunar missions per year (but even that will be hard to sell to Congress). I hope that once that we return to the Moon with Artemis III, we realize that we never should have left the Moon and decide to stay this time.

It's also not clear (at least to me) why an alternate HLV would be restricted to once a year, assuming it could get through Congress at all.

Other than "science", which really can be done with robotic systems instead of humans, there are no economic reasons for having a permanent presence on the Moon, nor are there any political reasons (i.e. a "Space Race").The Apollo program went to the Moon as part of winning the Cold War, and once we landed and safely returned the first humans to set foot on the Moon, that race was won. And no compelling reason to return to the Moon has been created since, other than "the first woman and first person of color", which are political goals, not scientific ones.The U.S. Taxpayer is primarily funding the Artemis program, and it is important to value the money they are contributing, because there are LOTS of other uses for that same money here on Earth. So let's keep the rationale for the Artemis program as realistic and honest as possible...My $0.02

As Robert Zubrin would say (and has said), Artemis is not a mission driven program, but a jobs-driven program. There has been some intriguing tinkering at the margins by Robert Zurbuchen, Kathy Leuders, and (yes) Jim Bridenstine, but not enough to change its basic orientation yet.As for the second, I think there *is* a possibility of a science driven HSF program on the Moon, just as there is for a human presence in the U.S. Antarctic Program: it just requires premises that are not in place yet. Yes, you can do a lot of science with robots, just not as efficiently as with humans (or, more ideally, a human and robots program). But we send robots to these places because we can actually *afford* them. I am not quite ready to demand a cost as low as the U.S. Antarctic Program (which scuttles along on less than $400 million annual budget), but it gives a fair idea that the cost of putting human scientists and technicians in place, and sustaining them, simply needs to get a whole lot lower and more reliable than anything NASA has managed to achieve, or will achieve with Artemis in its present form. A successful Starship program would be a giant step in that direction, but it is not the only prerequisite step. For one thing, VSECOTSPE's insistence that a well articulated science mission has to be thought out and fully inform the actual program, as is typically the case with SMD missions. Otherwise, maybe Andy Weir is right, and we'll only see humans on the Moon when some entrepreneurs figure out a way to do tourism there profitably.

So nothing to set up a supply & demand economy for (and don't say "Water!", since that is a self-licking ice cream cone).Science and politics, that is all that can come out of the Artemis program. Especially at the rate of $1B+ per person to get to the Moon, which makes it unaffordable for any private or corporate follow-on.

It's impossible to see how it even leads to this happening by any commercial entit(ies), unless some deep pocketed and determined (as in, Musk-level determined) billionaire or consortium decides it really wants to.Maybe if there were a permanently crewed base on the Moon, we could start talking about that. But that's not what NASA is planning to do, at present. Indeed, current leadership seems more worried about "getting bogged down" on the Moon.

The rational for a permanent human lunar presence is the same as any human space exploration to extend human presence to space.

Infect people with the proper mood.
Helping to create a lunar economy can be done through public-private partnerships just as is the case in LEO.
Like I’ve written here before, the insular, ingrown, engineering sandbox culture in NASA human space flight does not create meaningful, useful, or effective programs. Build it and they will come did not work for STS or for ISS, and it’s not working for Artemis.
That’s not a rationale. That’s a means, not an end.
unless ... someone finds ... a derelict alien spaceship...
That’s not a rationale. That’s a means, not an end. NSF extends human presence to Antarctica — not just to have a presence there but to do research. NOAA extends human presence to ocean depths — not just to have a presence there but to do research and manage resources. Adventure tourism companies extend human presence to the tops of the Himlayas — not just to have a presence there but to make a profit. Petroleum companies extend human presence far offshore — not just to have a presence there but to drill for oil and make a profit.This confusion of means with ends is a perpetual Apollo hangover problem for space cadets, including at NASA. Going there and being there are not enough and frankly of secondary importance. What you do there is what’s critical, and that’s what should be driving everything else. Without concrete ends and the organization to drive them into the means, human space flight is just playing with really dangerous toys in a really expensive sandbox.
