    Is it ok to shit on NASA for dumping so much money into developing Starship?

    Also the SLS doesn’t seem much better. But at least they’ve been around the moon on the SLS.

    Personally I’d rather they work on developing spacecraft that can be launch on Falcon 9 or Falcon 9 Heavies, even if it meant multiple launches and assembling things at the ISS before going to the Moon and onwards. Doing this during the Apollo era was difficult because docking operations weren’t all that reliable and there was no ISS back then so giant rockets was the way to go. But things have changed and dumping insane amounts of money into building massive rockets seems like a waste of money and probably isn’t as safe as using proven rocket systems.

      Are you joking? The SLS is a pretty major step backward for American spaceflight. If we continue flying the SLS, and make all the launches we plan (spoiler alert, that isn’t going to happen) then the cost per launch could be as low as $2 billion. But more likely we will end the SLS program when it proves to be a never ending money sink, and with so much money put into development, we’ll end up with a per launch cost upwards of $5 billion. Meanwhile, for that price it can only manage to get 95 tons to low Earth orbit.

      Compare this to the Saturn V, which could lift more and cost much less, even when adjusted for inflation. The Saturn V cost $185 million, or $1.23 billion adjusting for inflation. And it could put 141 tons into low Earth orbit.

      To sum up, this new rocket is much less capable and much more expensive than what we were doing 55 years ago.

      You could of course also compare this to what spaceX is doing… Their aim is to make a rocket of similar payload capability 100-150t, but with a per launch cost of about $100 million via reusability. That’s an order of magnitude of improvement, that’s huge.

          That’s actually a really good question. The short answer is that we don’t remember how to. A lot of the techniques used to actually make the parts were poorly documented. That was partly on purpose, everything was top secret because we didn’t want the Russians to know how we were doing it all. And now, all the people who did those jobs have gotten old and left the industry.

        Elon Musk promises a lot of things, but doesn’t have a good track record on delivering.

        SLS has at least been around the moon. I agree that it’s a step backwards, but Starship is two steps backwards. Just seems to be a knock-off of the Space Shuttle (which also proved to be a bad idea) that’s being developed by just blowing shit up. I hope I’m wrong about Starship, it would be awesome it it worked. But it’s the same goes fore the Space Shuttle too.

        But more likely we will end the SLS program when it proves to be a never ending money sink, and with so much money put into development, we’ll end up with a per launch cost upwards of $5 billion.

        SpaceX has already blown through $5 billion and hasn’t launched anything yet. Well yeah I guess they got it into space briefly… spinning out of control until it burnt up. They haven’t even gotten to the part of testing to make see if the heat tiles that we see peeling off the thing will make it go full Columbia on a regular basis. If it ever works it’ll be a long time before that thing gets man rated.

        Like I say, SLS sucks but it’s has a successful launch and has gotten around the Moon. Actually successful not SpaceX “successful”.

        SpaceX is currently losing the “bad idea space race” to NASA. The only winners in the Space race will be the billionaires that’ll make a lot of money from making giant rockets that go nowhere.
