Today was when they were supposed to try the SLS wet dress rehearsal again. Looks like they have a hydrogen leak somewhere in the GSE.

Same as before..... re-used shuttle hardware , that they've had IN this configuration for how many years now, and they can't successfully tank LH2?

SLS going back to the VAB for repairs before the next wet dress rehearsal probably in June

That thing will get as close to the moon as my Jeep Wrangler.

I've had my Jeep over 11,600ft. That's closer to the moon than that thing will get.

Good thing they aren't targeting a launch window...

I don't think they will get FAA approval until after SLS lights up.

I agree with both your, and his, assessment. I'm only giving SLS a 15-20% chance of a successful orbital flight. Giving it about a 5% chance of a successful mission completion.

That looks like it will be a damn LONG time. Before I was hoping they would hurry up and launch SLS, and that will perhaps green light Starship with the FAA since it would save face a little. Now I hope SLS get cancelled altogether, and the FAA, NASA, DoD, etc. all realize that SpaceX is our best shot. And that it is in all our best interest to allow them to innovate unabated.

I think at this point you'd have to think SLS won't launch before the fall, which brings the SRB fuel into play again.

Tho7ght they where already in play with the current NET estimate? Isn't it may or June?

I'm assuming the SRB issue goes something like this:
"We need another billion dollars or we won't be able to launch before the SRB expire!"

One year later

"The SRB deadline was mostly just for meaningless compliance issues. We do however need another billion or we won't be able to fulfill the compliance exceptions and beat next year's SRB expiration!"

Repeat for several years

They pencil whipped the SRB deadline in January already to extend it to what, 18 months? The issue I have read is the degradation of the seal between the segments. You'd think they could…have new segments ready to quickly stack (within a month) for a fresh set of SRB's, but of course this is SLS we are talking about.

Sounds like a multi-year, multi-million dollar fix to me.

NASA asks for more info/options for DragonXL:

Quote:

That's why the new April 1st RFI is so intriguing. NASA begins by referencing fine print in the original 2018 Gateway Logistics Services (GLS) Request For Proposals (RFP) that allows the agency to continue receiving and considering new proposals from new and existing providers throughout the program's planned 17-year lifespan. The agency says its primary motivations are for "information and planning purposes, to request feedback, to promote competition," and to "[determine] whether to conduct an on-ramp in 2022." NASA doesn't specify what exactly that means, but in the context of the rest of the text, it appears that the agency wants to use this RFI to help determine whether or not to finally "on-ramp" its existing Dragon XL contract with SpaceX.



NASA seems very interested in the potential benefits of alternative deep space cargo transport services that are both cheaper and more capable than Dragon XL. Between the lines, however, the RFI also reads as if it was written directly to SpaceX. The first question is perhaps the most telling: "Is your company interested in on-ramping to the GLS contract to provide Logistics Services as described in the original solicitation?"

SpaceX is the only company with an existing GLS contract that it could "on-ramp to" a roundabout way to say "start work on". In the following questions, NASA then repeatedly expresses interest in cargo transport capabilities well beyond the original contract's requirements and asks about innovative new capabilities that could enable such improvements. NASA even "recognizes" and hints at a willingness to consider unorthodox solutions that, for example, might require "more than one launch" per cargo delivery or help "minimize upfront costs to the Government." Put simply, while it does open the door for just about any US company to inform NASA about new GLS options, it's hard not to conclude that this new RFI is at least partially designed to give SpaceX an opportunity to propose Dragon XL alternatives or upgrades.

The most obvious option: Starship. Through the Human Landing System (HLS) program, NASA has already committed to investing at least $3 billion to develop a crewed Starship Moon lander and the fully-reusable launch vehicle and refueling infrastructure required to launch and operate it. With barely any modification, the Starship architecture SpaceX and NASA are already developing could be used to deliver dozens of tons of pressurized cargo to cislunar space, lunar orbit, the Gateway, the lunar surface, or just about anywhere else NASA wants. Leveraging that significant investment would also tick almost every box in NASA's new RFI by drastically reducing upfront and total development costs, helping to stimulate a "vibrant" deep space supply chain, and beating Dragon XL's cargo capabilities by a factor of 5, 10, or even 20+.

Of course, there are technical challenges and reasons to believe that Starship can't easily replace Dragon XL. Even Dragon XL risked running into Gateway's visiting vehicle mass limit of just 14 tons. Starship would likely weigh at least 100-200 tons more than the entire Gateway. Dragon XL would use non-cryogenic propellant and is baselined to spend at least 6-12 months at a time at the Gateway. NASA has also studied the possibility of using Dragon XL as a crew cabin or bathroom to temporarily relieve Gateway's extremely cramped habitable volume. Starship's main engines use cryogenic propellant that wants nothing more than to warm up and boil into gas, making it far harder to keep at the station for months at a time. Those problems are likely solvable, but it's still worth noting that Starship is not a perfect fit right out of the box.

The RFI could also end with a whimper if SpaceX simply tells NASA that it's happy to proceed with Dragon XL as proposed. Only time will tell. NASA is planning to hold an industry day on April 20th to better explain the RFI's goals and wants responses by May 31st, 2022, after which the agency will decide whether or not to follow up with a solicitation or on-ramp Dragon XL.
I don't think this is indicative of any certain move at all, but it seems to imply, this month, that the agency is considering options to move…past SLS.

Space government. Many enjoyable sci Fi novels deal with other planets/colonies throwing off the shackles of Earth's governments. Wonder how it'll all play out in real life once we establish real presences and self-sufficiency.

Hasn't started yet but would suspect calling out the usual suspects (prc, soviets, lil kim, etc) to be safe actors in space, to use space for the advancement of the good of humanity, to avoid the weaponization of space, etc. Will probably say a lot without saying much of anything concrete as to keep some operating space for us and not back ourselves into a corner IMO.

As suspected not much substance other than announcing US policy to commit to no destructive DA-ASAT testing while calling out the Russians and chicoms for their tests. Unclear if an "emergency" like the one that led to burnt frost is to be prohibited as well.
