I'm beginning to be convinced it will. NASA of course has better figures and some slightly better rocket engineers than I am. :D Another reason is political. SLS is built in Alabama. So is Vulcan/C-V. A lot of political horse trading was done before Cruz and others let the Commerce Committee pass the bill that, among other things, allows Jared to cancel the EUS. (Btw, we must keep in mind that hasn't made it thru Congress.) Also, Boeing owns half of ULA so it'll still be making money from each Artemis launch. A lot less than with SLS but better than nothing if the Orion-to-LEO job went to NG or FH.

With Orion being set for a Centaur V upper stage NASA could start launching it into LEO on Vulcan. Then there would be no need for Starliner, for LEO crew redundancy. And if a ferry stage were implemented to take it to the moon then SLS isn’t needed for Artemis. Boeing would not be happy.

Seeing as centaur first flew on Saturn I, does this mean SLS-Centaur has Saturn heritage?

Why are you spending your time on this? OK, nostalgia for what might have been - except the Bridenstack was never going to happen, it could never lift the complete ICPS-Orion with the LAS. And now we have all sorts of mission architectures to debate since a rocket needs to get only Orion to LEO. The big question is can Vulcan/Centaur V lift Orion. The figures look borderline to me but I'm sure NASA has better info. The alternatives are New Glenn or Falcon Heavy. All can lift that pair to LEO to meet Starship more easily than Vulcan. No more worries about TLI capability. The last two can easily do the lift. However, Jared's latest officially released plan said a standardized upper stage would be used for SLS and an eventual commercial successor sometime after Artemis V. The render showed what could only be a Centaur V. My guess is Jared's hope is Orion will launch on SLS for Artemis III and on Vulcan for Artemis IV. Very optimistic timing, so more like Artemis V. One convincing reason Vulcan will be used instead of NG or FH is that with that choice Boeing still gets a share of the pie since it owns half of ULA. It'd make sense if a back room deal was done in Congress to make cancelling SLS palatable for certain Congresscritters - especially since Vulcan and Centaur are built in Alabama, the same state as SLS.

Tbh used to think Bridenstack would never work because ICPS+Orion “only” gives 2700 m/s and you need 3200 m/s for TLI from LEO. But seeing as Orion has some extra margin for entering/exiting NRHO, maybe it’s not totally impossible. Idk.

@fakecarlsagan @DJSnM True, it'll get to LEO that way. But Orion is incredibly expensive for LEO-only missions. And non-reusable, except for interior components.

It's designed to take the thrust of 6. Even if they fit, adding two would require considerable redesign work. However, I'm starting to think using Vulcan/C-V has been the unstated plan, starting with using it on SLS. Isaacman said he wanted to use a standardized upper stage for both Artemis on SLS and on an unnamed commercial successor at some point after Artemis V. Then he springs the Orion ride-along on Starship. Then he says oh wait, since Orion now only needs a lift to LEO we have a commercial rocket currently that can use the standardized upper stage.

@Marc_Topaz @DJSnM I think NASA declaring Starliner unfit for purpose is the more likely outcome. NASA can cancel the contract for non-performance , for failure to meet the requirement, failure to deliver the crew-rated spacecraft contracted for.

@SpaceInMiBrain @DJSnM Yeah, as much as Starliner is a joke, this is still true. And Boeing still has a contract with NASA with three flight options authorized. Unless NASA can (and will) prove Starliner unfit for purpose. the cancellation fees on that contract won't be trivial.

There is a new addition to the US Space & Rocket Center Space Camp under construction and it is the Inspiration 4 Training Center! Initial funding in 2022 of $10 Million by @rookisaacman Jared Isaacman to initiate construction & at the time, it was the largest single donation in the history of the U.S. Space & Rocket Center! Expansion Funding of ~$15 Million in July 2025 was subsequently given by Jared and is designated for: Mission Operations: Supporting advanced simulations for Space Camp, Robotics, and Cyber Camp A new Dormitory: Providing seed money for a fourth dormitory to house students attending the programs. Really great to see funding of facilities and programs like this to inspire a new generation of space explorers! @Ellieinspace

At the time people mocked that Rumsfeld quote as word salad but, despite the source, it makes perfect sense and in fact would be extremely helpful for most people and institutions to internalize. Most don't acknowledge the existence of unknown unknowns!

@surelyagerbil @CJHandmer @pmarca @grok Grok got it right about Darwin regretting losing his love of poetry as he grew older but the basic statement is wrong, he didn't attribute it to his work. A classic AI mistake.

When I was on the ISS for my nearly year long mission, there was a telomere experiment comparing my telomeres to my earth baseline and my twin brother as a control. Hypothesis was they would get damaged and worse due to the environment. Turns out they got better. Initially NASA thought maybe it was due to exercise and diet. After I returned we learned JAXA had a telomere experiment on some small worms the same time I was there. Their telomeres got better too. Never saw the worms doing any exercise. After further study determined it was the radiation.

@piercepenniless "That is so wrong it isn't even incorrect." This quote is very apt for the statement about introspection in this video. It's by Wolfgang Pauli, a famous physicist.

Among the amazingly, amazingly stupid claims made here is the idea that nobody in the early 17th century was introspective, an idea so stupid it barely qualifies as an idea.

Great men of history had little to no introspection. The personality that builds empires is not the same personality that sits around quietly questioning itself. @pmarca and I discuss what we both noticed but no one talks about: David: You don't have any levels of introspection? Marc: Yes, zero. As little as possible. David: Why? Marc: Move forward. Go! I found people who dwell in the past get stuck in the past. It's a real problem and it's a problem at work and it's a problem at home. David: So I've read 400 biographies of history’s greatest entrepreneurs and someone asked me what the most surprising thing I’ve learned from this was [and I answered] they have little or zero introspection. Sam Walton didn't wake up thinking about his internal self. He just woke up and was like: I like building Walmart. I'm going to keep building Walmart. I'm going to make more Walmarts. And he just kept doing it over and over again. Marc: If you go back 400 years ago it never would've occurred to anybody to be introspective. All of the modern conceptions around introspection and therapy, and all the things that kind of result from that are, a kind of a manufacture of the 1910s, 1920s. Great men of history didn't sit around doing this stuff. The individual runs and does all these things and builds things and builds empires and builds companies and builds technology. And then this kind of this kind of guilt based whammy kind of showed up from Europe. A lot of it from Vienna in 1910, 1920s, Freud and all that entire movement. And kind of turned all that inward and basically said, okay, now we need to basically second guess the individual. We need to criticize the individual. The individual needs to self criticize. The individual needs to feel guilt, needs to look backwards, needs to dwell in the past. It never resonated with me.

Great Men are those who have the biggest impact on the worldview of their societies and the society of all humankind. Newton and Darwin had the most impact of any scientist in history. Copernicus also, to a limited extent. Their work broke the hold of religion as the sole source of a worldview. (Newton actually was a Christian but in his own idiosyncratic way.) It is difficult to explain how huge an impact that is. It transcended science and permeated all levels of society. Charles Darwin knew very well the impact his theory would have on society. It was a large part of why he spent almost 20 years honing his argument and researching everything he could to back it up before publishing.

In that he gave a theory of a model for change within species with a falsification - irreducible complexity - which has now been found many thousands of times - falsifying his magnum opus? Why are we still talking about Darwin except in lists of natural philosophers who got it wrong?
