    It’s so frustrating how expensive this thing is.

    I get that SLS and Orion have insane congressional approval. And keep getting overfunded because of it. And a lot of that money would go away without them. And there’s a lot of interesting development in HLS and CLPS that wouldn’t exist without them. But it still just stinks to see how expensive SLS is and that there’s basically nothing that can or will be done about it.

    • Are you familiar with Wernher von Braun? He was a Nazi who ran Germany’s V2 rocket program during World War II. He produced thousands of ballistic missiles intended to indiscriminately bombard British cities, they were unable to accurately target specific military sites so they were just aimed at civilian centers and let loose. Slave labor was used in their production, resulting in many thousands of innocent Jews and other concentration camp prisoners dying under hazardous conditions and bombardment of the manufacturing facilities.

      After the war he went to work for NASA and was the principle designer behind the Saturn V that took humanity to the Moon. Should NASA have repudiated the Saturn V design and gone with a less capable vehicle? Should people be responding “Fuck Nazi propaganda” whenever the virtues of the Saturn V are mentioned? Or is it possible to separate the evaluation of the merits of a rocket from the evaluation of the rocket’s designer?

      Elon Musk is a shitty person. The Starship is a fantastic rocket. Both of these things can be simultaneously true.

      • Interesting tidbit about the V2: as far as I know it’s the only weapons system that killed more people during the manufacturing process than it did in actual use. Casualties caused by V2 strikes are estimated to be around 9 000, but around 12 000 slave laborers died making them (see eg the wiki).

        In any case, comparing von Braun to Musk is uncharitable towards von Braun: he actually did design rockets and knew what he was doing, where Musk is just a bigoted windbag that emits money. But I do tend to agree with your sentiment though: SpaceX has good designs, but that’s completely separate from Musk being a human turd (and his only part in it is the part where he emits money.)

    • You can take SpaceX out of the equation and it still is a massive money spend.

      Compare the cost of the entire Apollo program (adjusted for inflation) to the SLS program.

      You might be surprised.

      • The numbers are bullshit. All money spent on NASA goes back to the economy. And it’s all public domain technology. Fascists would love to replace that will privately controlled technology.

        • How is a fixed price launch contract for SpaceX that different from a cost plus contract for Boeing to build an SLS as far as money going back to the economy? I genuinely don’t get how those are meaningfully different.

          How does the public domain technology actually matter, other than from an idealistic standpoint? NASA is even spinning off SLS production and management to be more private under EPOC to Deep Space Transport (Boeing+NG). They, along with Aerojet, basically get these sole-sourced, partially because of their non-public IP for making this stuff.

      • The GAO has performed an annual review of the Space Launch System every year since 2014 and switched to reviewing the Artemis program in 2019.

        Each year the GAO points out Nasa isn’t tracking any costs and Nasa argues with the GAO about the costs they assign. Then the GAO points out Nasa has no concrete plan to reduce costs, Nasa then goes nu’uh (see the articles cost reduction “objectives”).

        The last two reports have focused on the RS-25 engine, last time the GAO was unhappy because an engine cost Nasa $100 million and Nasa had just granted a development contract to reduce the cost of the engine.

        However if you took the headline cost of the contract and split it over planned engines it was greater than the desired cost savings. Nasa response was development costs don’t count.

        Congress reviews GAO reports and decides to give SLS more money.

  • This whole discussion about hydrogen is interesting, because my industry (oil but not really and shipping but not really; it’s complicated) MUST replace fuel oil in the very near future, and we have no fucking idea what to do about it. It’s mostly the IMO (the only UN agency wired real teeth) driving this, but there are some local actions, especially in the EU affecting it now too.

    No one and I mean no one has built out a non-fossil fuel based infrastructure for the ships that transport 90% of everything we consume on the planet. Right now, larger container ships seems to be moving to LNG, but some others are betting on bio methane, and some battery tech (good luck with that on anything bigger than a small ferry). And a bunch of other replacement fuels + incremental fuel savings + short tern carbon capture.

    It is absoluteluy no exaggeration to say that hundreds of billions of dollars, maybe more, over the next ten years at stake, so if you want to know what’s eventually going to have the energy density to fuel rockets, look at the developments in the shipping industry. Cause ships need nearly as much of it as rockets do, just over a much longer time frame.

    It will be interesting how Starship works out. Till now Spacex has been highly successful doing what has been done before but with new twists mostly reusability and without the defense providers pork. Also with vision vs. status quo.

    It is all cost per pound to orbit, moon, Mars, act. SLS is not it. Starship who knows yet. Amazes me how people do not want to try something new but are willimg to spend way more money on SLS.

    I am baffled by the SLS supporters. Where do people think the nutty costs go. Lot of it into overpaid executives and stock holders. I guess the one plus is that it pumps more money in to key political districts and keeps things status quo.

    Keep in mind too… I do not think Musk is a huge humanitarian. Nor are the owners and execs of the defense contractors that NASA usually uses.

    In a new report, the federal department charged with analyzing how efficiently US taxpayer dollars are spent, the Government Accountability Office, says NASA lacks transparency on the true costs of its Space Launch System rocket program.

    Published on Thursday, the new report (see .pdf) examines the billions of dollars spent by NASA on development of the massive rocket, which made a successful debut launch in late 2022 with the Artemis I mission.

    “Senior NASA officials told GAO that at current cost levels, the SLS program is unaffordable,” the new report states.

    The report also cites concerns about development costs of future hardware for NASA’s big-ticket rocket program, including the Exploration Upper Stage.

    “Some NASA officials told us that changes to Artemis mission dates should not affect the SLS program’s cost estimate,” the report states.

    “Other officials noted that the program’s cost estimate would be expected to increase to account for the delay to the Artemis IV mission, which shifted from 2026 to 2028.”
