Its never going to happen in your lifetime. if it does its just going to be hollow propaganda like the moon landings with no substantial contributions to the fate of the species.

Unironically this but in space.

>>10284830
Yeah but the "hollow" achievement will be the same like the wright brother airplane flight. It'll be remembered millennia from now because everyone in the far future living on other planets will look up "what was the first planet humans went to".

It'll be a Columbus moment. The moon is irrelevant because it wasn't another planet. In the far future barely anyone is going to remember neil armstrong because the moon is boring. It's like the first guy that went into space I bet only 10% of /sci/ can name him let alone the general public.

After the Mars landing the significance of neil armstrong and apollo 11 will severely diminish to the point of irrelevance.

This is why it's important the first person landing on Mars is a caucasian.

Ask the common man on the streets who was the first man on the moon. And then who was the first man in space. I bet you almost everyone will know Neil Armstrong and only a couple people will know Yuri.

>>10284951
It might be able to go to Mars, the difficulty will be returning. A bigger rocket means they need to immediately land a larger propellant plant or they can't go home. At least that's why Zubrin says it's not suitable for a Mars mission.

The upside of being a little late to Mars is SpaceX will probably be hired for at least a few lunar landing missions, too. And finally kill off SLS if it's still around, but most people think New Glenn flying while Falcon Heavy is in operation is the last element needed to do that.

The attraction is the not hard scifi, but very firm scifi underpinnings (until considerably down the story line but the soft stuff is still handled better than most: they try to avoid using "Space Magic" as an excuse as much as possible). Funny enough, it's set at about the same time as Star Trek: TOS in the mid-23rd century.
For example, the Epstein Drive (a very efficient fusion-based propulsion system) is why ships are laid out like skyscrapers instead of having rotating rings: propulsion is so efficient that most craft burn at between 0.3g and 1g toward their destination, then flip and brake at the same acceleration for the second half.

>>10285903
See, this is why I couldn't get into The Expanse: they mix a big ole' dollop of stupid into everything in the show.

Epstein of the Epstein Drive isn't some brilliant physicist who figures out how to make a fusion rocket, he's this sloppy tinker, who thinks he's going to get maybe a 4% improvement of fuel efficiency in the fusion rocket that was already off-the-shelf technology, just messing around with one he bought, basically on a whim (because fusion rockets were already cheap enough for a struggling young family to buy for fun). He accidentally makes a revolutionary improvement (since the pre-existing fusion rockets were somehow a disappointment), nearly killing himself because he's too fucking stupid to have any controls within easy reach, in his experimental rocket.

It's entirely ridiculous. They're presenting it like a big dramatic moment in the fictional history of the setting, but you're just sitting there thinking, "This is so fucking stupid. Who wrote this idiotic shit?"

That's the show in a nutshell. Lazy, forced drama that doesn't make any sense. Sloppily, lazily subverting expectations just for the sake of subversion.

The written version of the story points out that it's like buying a yacht. His ship was never supposed to go for long trips, it was big enough to maybe do a prospecting run to asteroids in the L-points around Earth or Mars. His adjustments were with that in mind.
You're right that the HUGE jump in efficiency is the point where you have to suspend disbelief, but otherwise it's possible someone could be enough of an idiot to include too few fail-safes, which is a smaller area where disbelief also needs to be suspended. A good one is there should have been an acceleration on the ship's drive controls purely because this kind of craft has no reason to burn hard enough to risk injury for its crew and passengers. It's a pleasure craft or something operated by a small prospecting interest, not a racing pinnace.

We've made so little progress on crewed space *anything* due only to a combination of lack of funding, lack of extended focus (president point NASA in different directions every 2 seconds), and problems with huge sums of cash disappearing into the endless chains of subcontractors utilized to fulfill Old Space's cost-plus contracts.

SpaceX already has the issues with lack of direction and grubby subcontractors fixed, all they need is solid funding. If they can secure that, I'm very confident that they can figure out the technical issues surrounding crewed space missions.

>>10286061
>You're right that the HUGE jump in efficiency is the point where you have to suspend disbelief
No, it's the point where you can't suspend disbelief. Where you have to suspend disbelief is that there are men riding around in fusion rockets. That's necessary to the story. That's essential to the setting. It's on you to accept this so you can enjoy the story. It's on the author to protect your ability to do so by not writing in a half-dozen ridiculous things together that don't fit in the setting.

The author needed to make it plausible within the setting, unless he's writing a comedy. This, "I tweaked the engine, and now it's accidentally a hundred times better, oh fuck" would fit perfectly in a sci-fi comedy.

None of this makes sense. Why wouldn't the controls be within easy reach of the pilot's chair? Why wouldn't it be programmed to shut down after reaching the target delta-v? If making some minor adjustments improves the performance so much, why wouldn't the people who designed the engine have noticed?

They could have had him working in a manic state, obsessive. When it comes time to test, he's been working on it for four days without sleep. This is his seventeenth attempt, every time before it just spluttered or components melted. He's sure he has it now, he can't rest before trying it out. He hasn't tweaked the engine, he designed a new one. Nobody else believes that it'll work, but he'll show them all! He's livestreaming it (though almost nobody is watching)! He's sleep-deprived to the point where his judgement is impaired, he's hallucinating. His theories were correct, his design was sound, but in his exhaustion and impatience he has made an elementary mistake in the final steps of construction, something so simple and basic that he rushed through it: no throttle control, not even shutdown. It goes on and stays on.

It's not hard to do this right. They're just lazy.

And this one is working well enough in very early checks that we think we've got it.

>>10286240
>And this one is working well enough in very early checks that we think we've got it.
Wendelstein 7X is also an order of magnitude short of useful fusion output.

>>10286255
The point is they think it can break even without much work. It's a small-scale system, and at the rate of its improvements second generation stellarators should deliver the promise of magnetic confinement fusion with a change in scale.
Funny as it seems, the Germans might just be saved by a single technical team that undoes its bureaucracies' deep and pervasive stupidity.

>>10286282
Wendelstein is a joke. The design will have to be regularly taken apart, refurbished and put back together because the neutrons fuck it up.

>>10286290
Considering it's a prototype, that's still better than the shitheap they're building in France that's based on 30-year-old concepts of fusion reactors. Even if Wendelstein is crappy and only sustains short sprints, if it can produce even a small amount of useful output its design lineage will be the winner in the long-term.

>>10286305
A machine that has to be rebuilt on a regular basis is a farce. SPARC is the only feasible design on the cards for something that doesn't constantly fall apart.

>>10286316
10T magnets sort of blow up after a while, no?

>>10286316
>SPARC
Still a Tokamak. Pure Tokamaks are a dead end, stellarators are a combination of improved modelling for magnet positioning and control. Tokamaks are subject to too many negative feedback loops that both inhibit reactions and damage the reactor itself.

>>10286320
They are solid state superconducting components, there is no reason to think they will just explode. Even if they do fail the operation to replace then is as simple as popping the top and swapping them. Compare this to wendelstein where the entire fucking thing has to be taken apart piece by piece.

>>10286332
...as one would expect of a first generation prototype with a limited budget.
There have been much wackier attempts at fusion, does anyone else remember that attempt at a liquid metal hydraulic hammer model?

this hour long presentation is a fantastic intro to the current state of fusion and SPARC. I would recommend it to anyone interested in the subject
