says right in the last paragraph "Based on a 4 segment Space Shuttle SRB", yet also says it could replace the current 5 segment booster design on future SLS rockets. Maybe the materials switch among other things brings the specific impulse up or the weight down or something else so it can do the job just as well? Maybe it's the switch from steel to carbon composites alone. Anyway SLS a shit.

Pretty sure they took the shuttle variant and upgraded it with some composites and another segment. So I think it's been designed separately from the SLS models.

So the station boosts itself into a higher orbit now and then in order to account for the thin drag it encounters, right? And the station is due to be decommissioned and allowed to deorbit sometime in the not to distant future?

Well we know that life in microgravity (leo) is generally really bad for your health, even if you excersise and try to combat the effects.

Life in low gravity would likely be better than in micro but still shitty. You could probably expect to excersise 2-4 hours a day minimum, and you would have to take calcium, iron, and vitamin D, daily.

That could have severe implications on the development of children. I won't go full jellow babies but it will have SOME effect.

The sad truth is that humans are optimised for a specific gravity and it's difficult if not impossible for us to thrive long term outside of that gravity.

I don't know if there ever be a full study on why SLS is taking a while, but I have found some legitimate reasons why the SLS has been taking longer than expected.

>The core tank is pretty much a new design compared to the Shuttle tank and thus required the factory that made Shuttle tanks to retool (and that ran into problems)
>The thrust structure which mounted the RS-25s kept breaking during testing
>The control computer had to be made new because the old Shuttle computer couldn't handle the new rocket in both software and hardware
>Apparently the software on the control computer was a nightmare to do, because NASA originally wanted to just build on top of old code which turned out to not be feasible

And there's probably some others that I'm missing. While you might think "those seem like legitimate issues, but that can't explain the massive delay", and I believe that you are correct. These did cause delays, but the delays ended up being protracted by the contractors building the SLS because NASA's management was practically encouraging them. Whenever a contractor didn't meet a milestone on time, NASA would just give them the reward money for meeting the milestone with essentially a pinky promise to be on schedule next time. While this along with other practices NASA was doing which encouraged slow development eventually (apparently) stopped after the OIG report on SLS last year, it perfectly explains why the SLS is taking so long. No one is motivated to anything quickly. In fact, there's motivation to take as long as possible to finish the thing.

Whenever if that's due to corruption, incompetence, or both is up to you, but it's shameful in any way.

>the old Shuttle computer couldn't handle the new rocket
Why did they think it would work in the first place? This isn't Shuttle, even if it used (or was supposed to) the same parts? Isn't it built around the 386 anyhow? Even Linux stopped supporting the 386 a few years ago.
Did they just get a conference of managers together with a Senate committee to design the thing? Was there no oversight on the initial design? How is any of this a "legitimate" reason? An excuse, maybe.

>Why did they think the old design was usable?
I don't think that the old tank was ever considered other than in the Jupiter proposal. It's just that getting the tooling in the Shuttle tank factory redone was a pain.

>Why didn't they know its structural limits, or notice that it needed reinforcement?
No clue. My guess is that they were practicing the old aerospace philosophy of only adding extra mass where absolutely necessary, so they decided to take the extra time to look into the data to find exactly where they need to reinforce the structure. I had a small tour of the place where NASA was testing the structure and they told me that it takes a month or two to look over the data from each test.

>Why did they think it would work in the first place?
Absolutely no clue. Management misunderstanding computing limitations and expecting the code monkeys to figure it out? I recall a discussion on NASA Watch where a supposed person working on the SLS avionics code (I can't find it now), and they said that management originally just wanted the Shuttle code to be quickly adapted to SLS.

>Did they just get a conference of managers together with a Senate committee to design the thing? Was there no oversight on the initial design?
Hard to say exactly what went on in the initial design of SLS without sounding like a conspiracy theorist, but I'd imagine that SLS was politically designed rather than practically designed.

>How is any of this a "legitimate" reason?
Are you referring to the avionics point or all of them. I mean, any of them result in delays which are understandable. Retooling is a pain in the ass. Testing stuff very carefully takes time. And management misunderstanding software limitations and just expect IT to fix everything. But my final point really was that these reasonable delays were overblown by poor management by NASA.

They're a bit more than that. They pretty much combine magnetic confinement with inertial confinement into one reactor. The ideal goal is to have a fusion reactor that can easily make a torid plasma that is self sustaining that is then shot down the axis of the reactor into a liner which then go through nuclear fusion to produce energy, and therefore thrust. The way I would do it would be to make the fusion reaction as small as possible but to increase the rate of pulses to hundreds of small fusion reactions per second. Then use the fusion reaction to heat reaction mass like Hydrogen or Methane to get blasted out of an actual nozzle like an afterburner. Therefore you can achieve both high efficiency(compared to chemical rockets) along with high thrust. In the hopes to making a spacecraft that would be capable of doing constant acceleration burns throughout its journey. Making travel times substantially shorter.

Apparently they detected trace amounts of neutron radiation from some of the tests, indicating that a tiny amount of the fuel being used was successfully fused along with the fact that there seemingly is nothing stopping them from simply upscaling the design into a much larger, much more powerful reactor. This whole idea of shear flow Z-pinch only goes as far back as 2006, and these tests were done in 2019. The plasma's being made are only 100cm long and 1cm in radius, there seems to be nothing stopping them from upping it to tens of meters in length and a meter or two in radius for massive fuck you power.

Cool feint but it represented the first real crewed mission of the program and so counted as "1" in the public imagination well before the mishap itself, and well before the bureaucracy retconned it at the widows' request. I invite you to square/cite the widows' request with a "publicity stunt", historically. Please, have a go at framing it in any other terms than an obligatory memorial, forced upon NASA by reality.

Fusing tiny amounts of atoms is easy. You can do that on a lab desk by shooting particles at each other. What you need is an efficient process to produce huge amounts of fusion power.
