Could they launch a BO transporter and a blue moon 2 lander on a space x SS?and sen the lander straight to the moon in 1 launch?
It will be more than V3 100t capacity and cargo bay volume. So, it will need V4 with longer cargo section and cargo bay doors, timeline - unknown, unknown if they even intent to do it.

So, it will need V4 with longer cargo section and cargo bay doors, timeline - unknown, unknown if they even intent to do it.V3 100t payload is for reusable configuration. However I have expendable propellant depot version in mind. Are they going to build propellant depot on V3 basis or V4? They probably don't need to build any propellant depot for a while. I don't think they would be willing to expend any tanker variant. For HLS demo landing they will need plenty of refueling so they will also need propellant depot and expendable starship version. Therefore I assume they will do the demo landing with propellant depot variant rather than with tanker variant. Also HLS should be build on it. At that time they can also be willing to do some super heavy cargo mission to LEO using this expendable variant. All it needs is just payload deployment. For really big cargo the nose cone ejection would work the best. The problem could be with huge stainless steel structure (nose cone) in LEO so perhaps the cargo would need it's own light weigh shroud with sub orbital disposal system. Not very comfortable or cheap but perhaps doable for 200t class payload.
Griffin reiterated that criticism on Thursday, without naming SpaceX or Blue Origin, and their Starship and Blue Moon Mk 2 landers.“The bottom line is that an architecture which requires a high number of refueling flights in low-Earth orbit, no one really knows how many, uses a technology that has not yet ever been demonstrated in space, is very unlikely to work—unlikely to the point where I will say it cannot work,” Griffin said.
Cheng said that whatever priorities policymakers decide for NASA, failing to achieve objectives should come with consequences.“One, it needs to be bipartisan, to make very clear throughout our system that this is something that everyone is pushing for,” Cheng said of establishing priorities for NASA. “And two, that there are consequences, budgetary, legal, and otherwise, to the agency, to supplying companies. If they fail to deliver on time and on budget, that it will not be a ‘Well, okay, let’s try again next year.’ There need to be consequences.”
I really hope no one listens to him for that bolded part, because unless we can figure out how to refuel in space, then humanity will never expand out into space.
This guy just reinvented FFP from first principles. Yes we already have this, it's called a FFP contract. If you go over budget then the budgetary consequence is you don't get one more penny to cover your expenses. And if you go over time, the extra work hours won't be covered by government either.

And I think it is in some ways funny that the person quoted as saying “It cannot work” is the person who came up with the first plan that would not work for returning to the Moon - Michael Griffin.
But Mike Griffin stresses it needs to be a GOOD plan, and Artemis is not. He continues to insist in-space refueling will not work because of boil-off. Only stick to a plan if it makes sense and this one doesn't. NASA should start over in his view.
A critical part of RRM3 is the demonstration of zero boil off storage of its 42 liter liquid methane supply through the use of active cooling. By using cryocoolers and advanced multilayer insulation to balance temperatures, RRM3 successfully stored liquid methane for four months with zero boil off, demonstrating a system which will dramatically lower fluid loss and eliminate the need for oversized tanks and extra propellant.
Our Lunar Permanence team is testing zero-boil-off technology to store liquid propellants at extremely low temperatures for Blue Origin’s lunar missions. We have successfully met all NASA - National Aeronautics and Space Administration objectives, demonstrating our ability to make liquid hydrogen and liquid oxygen in-space storable propellants at two times the performance of the current state of the art. This system is key to fueling our Blue Moon MK 2 lander, which will ultimately deliver astronauts to the Moon.
During that flight, SpaceX performed an in-flight propellant transfer demonstration under a NASA Tipping Point contract awarded in 2020. SpaceX planned to transfer at least 10 metric tons of liquid oxygen from a header tank to the main tank within the Starship upper stage while in space.While SpaceX said the day of the flight that it performed the demonstration, neither the company nor NASA provided any updates since then. At the advisory committee meeting, though, Kshatriya said the test appeared to go well.“On Flight 3, they did an intertank transfer of cryogens, which was successful by all accounts,” he said, adding that analysis of the test is ongoing.

Cruz noting that Artemis is crucial, and that space programs require stability. BBB provides clear guidance, for space stations in LEO, and Artemis. Asks for confirmation that Jared will follow that law. He says he will. Asking what long-term steps will be taken to maintain the Artemis program objectives. Jared saying that he believes that SLS is the quickest way to carry out the plan, and grateful for Artemis 4 and 5.
Isaacman agreed today with Duffy’s decision to reopen the HLS contract for Artemis III
During Wednesday’s hearing, Isaacman also faced questions about how he regained favor with Trump after having been on the outs for months. Sen. Gary Peters noted that Isaacman had recently donated roughly $2 million to President Trump’s Super PAC.Notably, when Trump first rescinded Isaacman’s first nomination in May, he appeared to indicate he took issue with Isaacman’s history of donating to Democrats as well as Republicans.
Criminal provisions of the United States Code prohibit offering or threatening federal jobs to induce payments, political activities, or contributions. Specifically, federal law prohibits anyone from asking for or receiving anything of value, including a campaign contribution, in return for promising to help someone obtain a federal post. Further, candidates may not directly or indirectly promise appointment or use of influence or support in obtaining “any public or private position or employment” in return for someone’s political support... These provisions carry penalties ranging to fines of $10,000 and imprisonment for two years.
“I wouldn’t even begin to want to speculate why the President nominated me,” Isaacman said Wednesday.Regarding his Trump Super PAC donations, Isaacman said that after his NASA nomination was rescinded — he considered a political career. “It shouldn’t be surprising that I supported the Republican Party,” he said.
Couple observations from Isaacman’s re-nomination hearing...1. At least publicly, Isaacman continues to buy the Orion/SLS-thru-Artemis-V argument hook, line, and sinker:
And Isaacman has agreed to the competition that could lead to a third lander:
For what should be obvious reasons, pay-for-play is patently illegal. You can’t dump millions into a politician’s campaign coffers in exchange for a federal position. Appointees are supposed to be the best qualified, not the highest bidders:QuoteCriminal provisions of the United States Code prohibit offering or threatening federal jobs to induce payments, political activities, or contributions.

In fairness to Isaacman, he tried to explain it away thusly:Quote“I wouldn’t even begin to want to speculate why the President nominated me,” Isaacman said Wednesday.Regarding his Trump Super PAC donations, Isaacman said that after his NASA nomination was rescinded — he considered a political career. “It shouldn’t be surprising that I supported the Republican Party,” he said.That said, I checked Isaacman’s political donations on OpenSecrets. Since 2014, he’s made only six donations to Republicans out of 37. He’s never made a seven- or six-digit donation to any politician or party. Isaacman’s largest political donation was only $50K. A $2M donation to the President’s Republican PAC is one heckuva an outlier. It doesn’t made sense absent the competition for the NASA Administrator nomination.

Adding more contractual requirements is not the answer.Look, it isn't the number of requirements that is the important metric, especially since not every complex system can be boiled down to a one paragraph description.I see two potentially big issues with the xEVAS contract, and I'm not even that familiar with it. But it is the same problem with many parts of the Artemis program, which is:1. Even though we've already been the Moon, we are returning in a completely different way, and that requires a completely new design for what is needed. And unfortunately NASA was not allowed to solve these challenges in a progressive way, but instead a completely fake need date was mandated to them. Well guess what, it turns out that you can't compress the amount of time it takes to mature new systems, and xEVAS is bleeding edge technology.2. With bleeding edge technology you get requirement changes, because the technology is so immature that changes are REQUIRED. Unfortunately that causes price increases and schedule changes, and then everyone on the outside of the program is pointing fingers while conveniently forgetting that fake need dates are the cause, not NASA or the contractors.
There's no contradiction here. Isaacman didn't donate a lot before because he [was] not interested in a political career before.

However, hardware is in flow now that supports SLS and Orion for flights beyond Artemis V. To interrupt the existing supply chain would risk putting in place another gap in U.S. human spaceflight capability – and as you rightfully stated in your testimony, we can never afford to let that happen again.Question 16: Mr. Isaacman, since we may not know the status or success of these alternative launch vehicles and landers for at least 3-4 more years, will you commit to maintaining the existing supply chain and progress on hardware to support future Artemis missions beyond Artemis V at least until such time as we have a new vehicle (or vehicles) in place that is fully certified to fly with humans?Answer: I will certainly commit to working with Congress and will always follow the law. As it stands, the One Big Beautiful Bill contemplates funding through Artemis V, and in that respect, I agree that SLS and Orion are the most expeditious path to meeting near-term lunar objectives. However, it is worth acknowledging the cost of SLS as highlighted by NASA’s Inspector General, and recognizing that if we want an enduring presence on the Moon--with mission cadence greater than every few years--and future missions to Mars and beyond, it will be imperative to eventually pivot to an architecture that enables more frequent and affordable launches.

RANKING MEMBER MARIA CANTWELL (D-WA)Commitment to Competition and Redundancy for Critical Missions As we discussed during thehearing, NASA’s exploration programs are faced with steep competition from China. Givensignificant taxpayer investment in these programs, the United States cannot afford to allowcritical missions to have a single point of failure and must ensure that contract formulationfosters competition among commercial providers.Question 1: I appreciated the comments you made during our exchange in support of competitionbetween SpaceX and Blue Origin. However, I have been made aware that contracting differencesbetween the two HLS providers may not provide an even playing field for them to compete forthe Artemis III mission. For example, SpaceX is contracted for Artemis III with fewerrequirements, while Blue Origin is not on contract to deliver until the Artemis V mission and hasmore requirements. What is your plan to put both providers on equal footing, making Artemis IIIa true competition so the U.S. can beat China to the Moon?Answer: If confirmed, I fully intend to solicit feedback from all commercial partners onways to reduce requirements and remove obstacles that impede America’s near-termlunar objectives. This applies not only to Blue Origin and SpaceX, but to LockheedMartin, Boeing, Northrop, and every other vendor contributing to Artemis and NASA’sbroader mission. As I stated during the hearing, America is best served when both HLSproviders are able to compete--and as a nation, we must select the first landing systemready to ensure the United States returns to the Moon before China.
