Could chemical thermal rockets be a cheaper alternative to nuclear thermal rockets?

Essentially use a conventional cryogenic fuel combustion cycle, but instead of using thrust directly from that, use the heat from it to boil water into steam thus converting far more of the thermal energy into kinetic energy. You can have an ordinary combustion chamber and a large water injection chamber underneath that and finally a conventional bell nozzle. Since the temperature of the exhaust gas would be much cooler than from combustion alone it could potentially allow for greater engine reusability.

The trade off would be having to carry a third tank for the expandant but this could be offset by needing to carry less cryogenic fuel.

It's promising that a handful of distant objects, such as Sedna, Makemake, and a spot on Haumea, are red. I'd imagine those have interesting surfaces. Not sure about Eris, but since it's the largest known but unexplored object in the solar system, it might be worth the long trip there.

Well, he did require them to completely redo their capsule test, which isn't strictly speaking necessary to fix the programming errors. It was (in my estimation) a deliberate move which he knew would set them back well behind their competitor, SpaceX and NASA as well. It's about as explicit as you can be when trying to punish a defense contractor without risking your career, if the literally came out and said "because Boing! is a fuckup and can't programme for shit we're cutting their contract for capsule making until they prove to us their space division is competent again" the Boing! lobbyists would be a mile up Shelby's ass begging and demanding that he put a word into Trump's ear that Bridenstine just isn't the guy for the job at NASA.
He's still gotta play it passive agressive, like forcing Boing! to take a two year delay and eat their own development costs, or passing them over in a lander contract for some smaller company with less pedigree. Even including SpaceX in the lander contract was a bit of a backhanded insult to Boing!, it sends the message that NASA now trusts SpaceX enough with rocket technology to give them money to develop a lander but they don't trust Boing!.

The part that honestly kills me is how we never followed up on the Voyager flybys of Uranus/Neptune with any sort of ongoing mission.

We should have stuck to the Galileo-Cassini mission cadence and launched Galileo/Cassini-tier long-duration probes to Uranus and Neptune as well. Imagine if right now we were all eagerly awaiting the footage to come from the RTG-powered lander that was about to be dropped onto Triton from the Neptune orbiter that launched in 2009. Imagine if instead of just New Horizons, the early 2010s also saw us all agape or the teams of data and high-res photos coming from the Uranus orbiter that launched in 2004 and entered orbit around Uranus and it's moons in 2011.

That would've been incredibly depressing to live through, especially if the US never opened up space flight to the private sector. Any kind of project larger in scope than another comsat launch wouldn't be taken seriously, any kind of speculation would be treated like cheap sci-fi no matter how well researched it is, and what would be worse is that we would think that the inefficient government ways of doing space flight would be the only way to go to space.

I think Trump would support Jim on that. He's had bad experiences with Alabama Senators before, and Jim has been objectively amazing at his job. The real problem is that Boing! has literally no competition for commercial airliners or airliner-equivalent military aircraft (P-8, KC-135, etc.) unless someone takes an anti trust hammer to them, which DOJ doesn't really have the bandwidth to do right now, so it's easier for the government to leave them alone until Communists stop burning cities.

The US might be the only substantial space power right now, but that won't last forever if Russia, China, India, Yurop, etc have any sense, there is no reason for any of the rest of them to respect such legislation when an injection of resources from a large belt rock or small moonlet would vastly surpass any damage done by economic retribution.

Yeah, without super fast travel between Earth and Mars (and even then...) Mars will become independent some times after they're self-sufficient.
The real question is whether this independence will be violent or not.
The thing is that everybody with a minimal knowledge of history will see that. So apart from Elon who does this because he want humanity to become multi-planetary, a Mars colony will need investors (including countries) who either:
- are too dumb to see it happen
- think they will be able to make a profit anyway by pulling before independence
- think (their) business will continue after independence without too much disruption

>>12075060
You absolutely wouldn't need a rocket the size of F9 to get an animal the size of a frog to the moon alive, if you wanted to land one American bullfrog on the Moon and you chose a specimen of average weight (1.5 pounds), assuming all else is equal you'd need a vehicle only one one hundredth the weight of the Apollo CSM and LM, just a shade less than 400kg. Electron can put 300kg into LEO, so you'd need to increase the size of the rocket by only about 25-30%, and maybe some more on top for some extra margins. Say a rocket with dimensions approximately 21x1.5m.

Assuming we were dedicated, had a million or two in startup capital, and any of us actually know what the fuck we're doing outside of the internet, such a mission could be put together in a relatively short amount of time, assuming it's a one-time shot.

>Ars Technica reporter Eric Berger had just posted a string of tweets about opposition to refueling depots in congress back when the SLS program picked up steam. Then, former ULA manager George Sowers replied with his perspective. According to Sowers, his ULA advanced programs group had published several papers on the use of orbital refueling depots. He claims his team demonstrated that pre-existing commercial rockets could do the job of something like the SLS. The key was a platform being developed at ULA called the Advanced Cryogenic Evolved Stage, or ACES.
>In 2011, ULA wanted to test ACES in space to show that it could serve as a refueling depot to get rockets to more distant locations. Sowers said Boeing (which operates ULA along with Lockheed Martin) was incensed by his team’s push for refueling depots. Boeing was, and still is, the primary contractor on the SLS launch vehicle. A shift toward cheaper refueling technology could cost it a juicy government contract.
>Sowers says Boeing executives tried to get him fired, but his direct managers held the line. However, ACES was quietly shelved. Around the same time, Berger reports that Alabama Senator Richard Shelby told NASA, “No more f—ing depots.” His home state is home to Marshall Space Flight Center and stood to benefit greatly from SLS development.

Interesting, would they survive if we managed to create an internal ecosystem that supplied a lot of oxygen? Like stromatolites or something?
Also my pea brain is struggling trying to think of the physics of this... most fish have swim bladders that create a buoyant force for them to float. But there’s no “gravity” in microgravity. Yet... I still feel like they would be able to float and push water around with their fins to swim... although they wouldn’t know which direction is “up” since that doesn’t really exist.
Also what about dolphins? I can’t think of a way we could get them in space where they could “surface” for air. Are humans just lucky that we have a simple way to get to space so long as we have breathable air?

Honestly i think if you raised a few gens of fish in microgravity they would adapt to it just fine.

[Anonymous No.12075390]

A couple of threads back some anon mentioned this thing called breathable liquids. It sent me down a rabbit hike and apparently there are some that can dissolve more oxygen than blood can. We could put dolphins in a breathable liquid capsule and send them to space. Even land them on the Moon or Mars and program a rover that drives them wherever they want to go. Unfortunately though they would probably be bored. I don’t think dolphins give a shit about rocks. I think we are the only species capable of understanding what it means to “leave Earth” and “visit an entirely different planet”. Sucks that there isn’t more intelligent life we can interact with

Technically yeah but at that point they might as well be on earth if you’re going to induce gravity, no microgravity research can be done if you rotate the habitat. I suppose it would be useful if you wanted to slowly turn down the rotation over time to see the effects on the fish as gravity gets lower and lower (especially cool if you want to see what happens to their offspring in lower gravity enviroments). Also useful if you’re trying to ship a shitload to Mars to feed colonists. Idk how you could land them on the surface though

Huh, ten years from concept to test firing and test flights is lightning fast for a large sized LPRE not being rushed by the space race. I'd imagine that some of the mechanical processes now being used to manufacture Raptor barely even existed back when it was first thought up.
Interesting that they thought up the engine before thinking up a vehicle to fly with it. To my mind it seems like it would make more sense to figure out what you want from a lifter and then design an engine to cover a reasonable number of different use cases for it.

I think low gravity is a significant enough factor to make true colonization of most planets not a reasonable option except in the most dire circumstances. While colonies on Venus would likely take an extremely long time to reach notable industrial capacity, or maybe even self-sustainability, they would be the most livable "on-planet" colonies. As much as I hate Blue Origin, I do think Bezos is completely right in saying that space habitation is going to be the prime way forward of allowing humans to live long-term off Earth. Colonies on low-gravity planets will likely end up seen in a similar light to how the ISS is today. Well, somewhere between that and working on an oil rig, but certainly not multi-generational living.

A fully-reusable smallsat launcher would probably be a good direction to go in, but it seems totally contrary to the direction they've been heading. It would require novel recovery techniques that I doubt they have the resources to develop.

In terms of effort, it's not even close, building on Mars is better. Eventually though Mars will have enough industrial capability that they will stop ignoring the quadrillions of megagrams of building material orbiting their planet, and they'll start figuring out how to build and mass produce gigantic stations and ships with rotation-induced artificial G that they can use to slow-boat to anywhere in the solar system, arriving with an already mostly self sustaining population and industrial capacity.
From there, we are literally one technological development step away from being able to do long term interstellar colonization on a galactic scale (fusion energy, and fusion based engines).

Tunnel bores are pretty useful here on Earth too though, that at least is a service Elon can definitely deliver on.
While a vacuum tube maglev might be outside the boundaries of what's practical in an environment with an ambient pressure of 1 bar, I'm still fairly certain the investment and research into hyperloop will generate useful technology at some point. After all it isn't the first maglev train proposed, that goes back to the 70's with a variety of different concept vehicles, some were even built and showed incredible promise for mass transit, but as usual institutional inertia and investment skittishness did them in.
There again Elon might be able to push investment over the hurdle to actually producing a marketable technology, by using his cult following to drive investment enthusiasm when more cautious industry people would normally not even bother to take a chance.

Call me a schizophrenic but I'm becoming increasingly convinced that NASA has been taken over and sabotaged by a splinter cell of the catholic church.

They sent their wealthy catholic conservative engineers and politicians to infiltrate NASA after the Apollo program with the goal of quietly destroying the space program from within and ensuring humanity never leaves Earth. Their motivation is from religious reasons alone; they believe it is sacrilege for man to abandon the "garden" of earth that god gifted onto him, and probably fear the direct wrath of god as retaliation. They may even have deliberately allowed the challenger disaster to happen knowing it would shatter the public's faith in the space program.

But they don't just destroy everything outright; they release new concepts of missions and vehicles so the public doesn't become suspicious. But the SLS should be proof enough that they have no real intention of expanding the space program.

Propane requires more processing, but not impossible. Pointless though since you're not really getting any more energy into it by weight, but you're getting more carbon into the mix which means more junk to clean out of your engines.

Kerolox and propalox are better for Earth first stages because they're denser, so you get more thrust for a given tank volume.

Tory Bruno actually answered this on Twitter. He admitted any time a rocket engine is described as "LNG" it's actually methalox with an investor-friendly name.

Well, technically you could probably go the plant diesel fuel oil route, but who the fuck would grow canola on Mars to convert to diesel to then further autistically refine to RP-1?

Will Falcon 9 make 100s this year?

Maybe. They've been stepping it up recently, but weather has had other plans.

That and you'd reduce the lifetime of the engine if you made it a full flow staged combustion cycle. Even though the NK-33 engine was disposable, I guess even with its alloys, it would not last long after repeated use.

Are storable non-toxic propellants (or storable propellants that produce non-toxic exhaust gases) a meme?

I've been brainstorming an idea for a "dirt cheap" fully reusable TSTO satellite launcher. Both the first and seconds stages land retrospectively like a falcon and the second stage is essentially a self-propelled permanently affixed payload bay with opening doors. I was hoping replace LOX with either N2O or N2O4 to make for cheap storable propellants and launch scrub security (the rocket can simply wait for the weather to improve to launch). I would even put an abort tower on the second stage despite having no crew aboard to reassure the customer that their payload won't go up in flames.

This "Dolphin 20" rocket will be the first member of the Dolphin rocket family. The "20" stands for the max payload to LEO in Tonnes. It may be followed up by a larger Dolphin 50 and finally a Dolphin ultimate (200 tonnes to LEO).

In my imaginary spaceflight company, we will establish the practice of naming our vehicles and major hardware after assorted sea creatures, though I'm still trying to find an appropriate name for the company itself.

Threadly reminder that this insidious menace known as "the environment" must be defeated and subjugated by man if we are ever to tame other worlds. Too long has Gaia's cruel and random wrath torn asunder the dreams of mankind, it's about time we dick that deity down and make her our bitch.

Make it Roman Numerals. Instead of Dolphin 20 it’s Dolphin XX. Dolphin 50 is the Dolphin L. As for a company name, I think Panthalassa is a good name; named after the super ocean surrounding Pangaea

Such a shame that it turned into a glorified garbage scow.
And we need a new thread, we're on page 10.

Lmao it’s probably ready to fly within the next 6 months. NASA just doesn’t want it to arrive before the Starliner test as to not embarrass Boeing!
