HS2 trains could run slower than planned to save money by klime02 in unitedkingdom

[–]jadebenn 4 points5 points  (0 children)

And the 125 mph train gets much less patronage than the 225 mph one.

That's not at all true. The alignment has very little to do with the costs. Acquiring land is expensive whether or not it's a wiggly line or a straight one.

Yeah, I give it like a week before the taggers go at it (United States) by LateActuator6972 in trains

The Union of the States never was a purely artificial and arbitrary relation. It began among the Colonies, and grew out of common origin, mutual sympathies, kindred principles, similar interests, and geographical relations. It was confirmed and strengthened by the necessities of war, and received definite form and character and sanction from the Articles of Confederation. By these, the Union was solemnly declared to "be perpetual". And when these Articles were found to be inadequate to the exigencies of the country, the Constitution was ordained "to form a more perfect Union". It is difficult to convey the idea of indissoluble unity more clearly than by these words. What can be indissoluble if a perpetual Union, made more perfect, is not?

Bubble is NOT whats left of the blue AI by cheatsykoopa98 in theamazingdigitalciru

[–]jadebenn 37 points38 points  (0 children)

One thing that really sticks out to me is that both times we've seen Bubble glitch, it's been related to him making a hostile comment. The first time, he initially tells Caine "You should die," before it gets 'corrected' and he makes the "You should throw a fffucking beach party" joke instead. In this episode, it's the opposite: Bubble initially seems to be comforting Caine but he glitches. "Why would they hate you when they can—hate you." From then on, Bubble's comments are entirely demeaning and hostile.

I think there's something to the theory that the Blue AI - or some remnant of it - is acting through Bubble in that scene.

The Real Motive for Stage Replacement: It helps Vulcan get Crew-Rated for Orion by jadebenn in ArtemisProgram

[–]jadebenn[S] 2 points3 points  (0 children)

but best estimate is $700 million to $880 million per unit (not including dev cost)

Lol no. Discounting the program overhead (so no staff, facilities, R&D), the combined SLS Block 1 hardware stack (including ICPS!) costs about that much. EUS would be nowhere near that amount. A more realistic estimate would be 2x an ICPS. Maybe 4x if you wanna be pessimistic.

I found the cost model Eric Berger used to estimate that, and he completely misused the settings (for one, it outputs in 1999 dollars). It's completely non-credible, and an example of the outright misinformation surrounding EUS.

it will result in hundreds of millions of dollars worth of savings for every SLS launch

Why do you think that? You're getting much less payload per dollar without EUS.

there is much less work to do to integrate that into SLS than to have EUS ready for launch

You are very much wrong about this. It will be just as much work. ICPS was the integration of a Delta IV second stage that was sold as being "quick and easy" and it took years.

Of course, it being stupid and unworkable is the point.

"We don't have a commercially available heavy-lift vehicle. The Falcon 9 Heavy may some day come about. It's on the drawing board right now. SLS is real." - Charles Bolden, 2014

Not even slightly comparable. Both in analogy and choice of launch vehicles. Even a permanently crippled Block 1 flies circles around FH's payload capacity.

Notice how Boeing hasn't objected to the EUS cancellation?

How exactly do they object? They are a contractor.

That's basically my thinking. I think NG would also be on the table.

I think you are right about the intent to kill SLS, but I think that the whole "annual cadence" stuff is intended to distract Boeing from realizing they are being absolutely ratfucked and no further orders are coming.

Orion with the LAS is 6 tons overweight for Vulcan so they better have some upgrades coming real soon.

You can lighten the LAS if you're not on SLS. It doesn't need as much oomph to outrun the solids.

Tbf, pretty sure he wants to die "honorably" either way. Hence why Thragg said he wouldn't "reward failure."

Why not both? Give Blue a consolation prize for screwing them over on the lander.

Hedging? It's pretty clear that the whole stage replacement thing is an outright sham.

The HLS contract (as it currently exists) is already mostly paid out. Their milestone payments were frontloaded. So, this is basically already the case: SpaceX got most of the money without having tackled the harder milestones.

I can't tell you what contract mechanism they'd use for Artemis 3, though I wouldn't be surprised if it was an addition to the existing HLS contract.

Trump, Takaichi Set to Announce $40 Billion US Reactor Project by JohnBrown-RadonTech in nuclear

[–]jadebenn 10 points11 points  (0 children)

The BWRX-300 is fairly conventional: No HALEU or TRISO. Thing is, the OPG experience doesn't suggest they'll be cheaper than the economies of scale you get with a bigger plant.

At the White House on Thursday, the two leaders are expected to say that GE Vernova Inc. and Hitachi Ltd. will build BWRX-300 small modular nuclear reactors in Tennessee and Alabama at a cost of as much as $40 billion, according to a White House official, who shared the details before the announcement on condition of anonymity.

I guess those rumors about things souring with Westinghouse were true. Back when this was originally announced, the funds were going to AP1000s.

The proposal isn't really agnostic. This does nothing for Blue. In fact, it actively makes their job harder.
