I started thinking about those spin station concepts, like there was one that was meant to be just a tourist destination but with artificial gravity. But if you were a space tourist, wouldn't it be more exciting to float around instead of just being in normal gravity but in orbit?

central spine of the station would be in micrograv, increasing to whatever arbitrary G amount (GAINZSTATION will be reall inshallah) as you go along the radius towards the outermost ring section.

you could have multiple rings with different G loads on the same station with decreasing radii, thus allowing dyels, the elderly, and utterly infirm (mars-ers) to coexist

This world lied to you about literally everything. Either half-truths, false concepts, or blatant lies. To confuse you and give you a false understanding of the world, mankind, time, history, and your place in it. So that you dedicate your life, soul, and energy to their doctrines in which they have full authority over every aspect. They control Science™, they are the priests that ex-plain and ex-plane the earth for you, they wield that trademark, and that means they control our space in life (if we give them authority over the earth).
Right from the start this world lied to you about the very ground you stand on, the 3 dimensional reality you live in. A fundamental lie, and everything people derive from this false reality will consequently be some kind of falsehood. We are now at the point where mankind believes they are mutated animals, and they are spinning around themselves on a perfectly spherical rock in random space that exploded once. A psy-op, mental conditioning. Do not underestimate the spiritual life-guiding implications of this godless concept. Most people are not level-headed, they are not stationary, they are not based, they are incapable to see physical truth at this point. Common sense isn't really all that common anymore. They rather believe in jewish mysticism like space-time and relativity, which leads to everything being "relative". No distinct up and down, which leads to good and evil being "relative", male and female being "relative", all empty space and imaginations in our mind. Let that sink in, the majority of people ultimately don't even know what is UP and what is DOWN. In other words, there is no absolute truth in this universe.

Problem with a cylinder is that you need a lot of air to fill it, way more than a torus. I think they'll ultimately be built but not until lunar and NEA industry is very mature. A torus makes a good design for initial efforts

[Anonymous No.15426806]

>>15426683
the insane amount of internal volume that's just left as empty air space; space stations are hard constrained by pressurised volume and having literally 90%+ be unused ruins the ratio of the amount of actually useful space versus the mass of the station. such a monster sized cylinder requires humungous wall thickness when you could get an equivalent *actually useful* volume for like 1/10th the material as a donut.

>>15426716
there was a planned space shuttle mission to deliver a sat to polar orbit, STS-62A but it never happened. I think the Voskhod 1&2 missions are the closest any human ever actually flew to polar, but they're only 64 degree inclination.

[Anonymous No.15426818]

>>15426806
If you're making a cylinder enclosed like a stretched donut then you're wasting tons of material and mass on effectively building your floor again just to hold in the air. With a cylinder which is hollow like a soda can the only extra material you need is for the ends. The center space is going to be largely or entirely wasted either way. The soda can only requires more air.

Why does this make you seethe? More airspace means greater life support stability.

>>15426818
not him, but you're not making sense anon, you can get more livable surface area with less material using a torus, it's as simple as that.
I wouldn't bother with either, but it's clear one is superior to the other in terms of habitation.
>>15426822
just build more reliable life support instead of wasting volume, easy enough.

[Anonymous No.15426827]

>>15426818
except the additional volume means thicker walls for the pressure vessel, all for what you clearly understand to be wasted space. it's not impossible that they'll be built eventually, but the combination of more difficult construction and more material (mass) needed means the donut will win 10 times out of 10 at least until this guy's >>15426804 lunar industry comes about

no, the soda can requires a top and a bottom to enclose the air which means it needs to be much, much larger than the equivalent surface area of donuts to require fewer materials.

Rate my idea: starlink but for space telescopes
A couple dozen cheap telescopes that aren’t good enough to compete with hubble or jwst or anything, but can be mass manufactured. Throw them in LEO and rent them out to astrophotographers and universities and whoever else wants them. This way they can stop bitching about satellite lines in their photos and as a bonus they don’t have to worry about clouds or the atmosphere getting in the way.

[Anonymous No.15426838]

>>15426830
no he's right - the same volume of toruses would have way more surface area, but because of complicated shit involving the relationship between pressure vessel volume and wall thickness and hoop strain and other things I'm too unenergetic to get into, you end up needing more mass of material for the pop can style than for an equivalent internal useful surface area as a torus.

This meme exists only to justify the fake narrative that current space telescopes are "usefull" for exoplanet biosignatures search. if scientists would be sincere about red dwarf systems, they would have to concede that their shiny new telescopes are only usefull at searching for the life in the places where life can't exist by definition. JSWT for example couldn't detect atmospheric spectra of Earth, if it were 10 light away from us. It can only get some results if Earth would pass in front or behind the Sun, two times a year and it would need around 40 passes, so JSWT would need 20 years just to characterize the atmosphere of second Earth if it was very close to JSWT as to be in 10 light years and alligned for possible eclipses and transits.

More than 75% of stars are M dwarfs. If you assume they cannot be habitable under any circumstances you're literally giving up on the majority of targets. It is a huge assumption. And what do you base this on? One measurement of the closest planet in one system. If M dwarfs and uninhabitable then that should be established robustly, rather than just guessing. People literally lost out on a Nobel prize because they assumed there would be no short-period massive planets, and then the Swiss found there was a whole class of them. There are many examples of dogmatic assumptions being overturned.

The dogmatic assumption in this case is the HABITABILITY of the planets around red dwarfs, not their uninhabitability.

>And what definition of life is this?
The one that requires liquid medium under pressure. Planets around red dwarfs are tidally locked hellwords with no atmosphere, just hellish landscape on one side and frozen moonshit on the other side. Now of course in some underglacial cavepit on the other side can be some pressure for liquid water, but that world doesn't have atmosphere, there is nothing to analyze, that life can never get out and see Red Evil Sun of Death stuck in place on the airless horizon.

Last year I was trying to make an open-cycle rocket engine using hydrogen peroxide, but failed because 3D printed parts are fragile, leaky, take an eternity to print and are a pain to model (specially turbines).
I almost gave up until I had an idea last week: Instead of making a traditional turbopump, I could use piston designs for the pumps and the "turbine" (which now would be like a car engine), so I could use pvc pipes for the piston chambers and have way less 3D printed parts.
I'm working on it now but I noticed no real rocket engines utilize this design - why? Is it so inefficient it isn't worth it?
Also, any suggestions for the engine?

Its simple math. Red Dwarfs are more active than the Sun, you don't need citations to know this, just go and read any astronomy book.

And here is the killer - if they are within Mercury orbit, they get showered by neutrons. Our Sun also emits neutrons, but most of them decay before they reach Earth, so we don't really suffer from them, but if the planet is very close to the very active star, it gets a lot of neutrons. And neutrons = death.

And yet a lot of them would. Because traveling even mildly relativisticly they would get here before decaying. And yet, solar neutron events are very rare and hard to detect at all.

>Explanation: Can you find two Earth shadows in today's image? It's a bit tricky. To find the first shadow, observe that the top part of the atmosphere appears pink and the lower part appears blue. This is because the top half is exposed to direct sunlight, while the lower part is not. The purple area in between is known as the Belt of Venus, even though Venus can only appear on the other side of the sky, near the Sun. The blue color of the lower atmosphere is caused by the Earth blocking sunlight, creating Earth shadow number 1. Now, where is the second Earth shadow? Take a look at the Moon. Do you notice something unusual about the lower left part? That area appears unusually dark because it is in the shadow of the Earth, creating Earth shadow number 2. To be precise, the Moon was captured during a lunar eclipse. This carefully timed image was taken in Sampieri, Sicily, Italy, in July 2018.

for the uninitiated
>For instance: Skylab was the first space vehicle in which the astronauts ate at a table using spoons and forks, rather than squeezing everything from tubes and baggies. Their table was a mere pedestal that supported their food trays. There were seats, but those were seldom used: to stay in a sitting position in zero gravity requires that you bend at the waist and hold yourself bent. It puts a constant and severe strain on stomach muscles, and in fact those were the only muscles better developed when the crew landed than when they went up. The real problem, though, was the table itself.
>It didn't do a very good job of holding the trays, to begin with. They tray lids were held down with what Lousma called "the most miserable latch that's ever been designed in the history of mankind or maybe before."

The difference in the rocket equation. Hydrolox has higher Isp but higher dry mass, it's close to a wash when it comes to dV. Electric propulsion has high Isp and high dV, no question, but it's largely limited by the mass of the power system, particularly if we're talking about transits to nearer planets because of how slow they accelerate.

Power sails flip the script. VASIMR's "Mars in 39 days" assumed a specific power of 1,000 W/kg, which is effectively impossible with nuclear but completely plausible with near future solar, and no the VASIMR engine itself isn't necessary for such a transit before we get into how disappointing it is. Nested hall thrusters could easily serve that task.
>>15427415

Should be less than one square kilometer of area with ~25% efficiency but I haven't looked at the rest of their assumptions to see what mass could be cut or what exactly the payload consists of. Obviously 10,000 W/kg would greatly reduce the amount of area required as the mass fraction improves.

Another option is to just leave the array in a fixed orbit and beam the power over to the spacecraft. Solar power sails would be great for laser thermal and laser electric.

This is probably not true. The mass fraction does improve as dry mass goes down, but unless the array structures are mass-dominant, making them lighter will not have a particularly dramatic impact on the structural mass of the spacecraft.

[Anonymous No.15427496]

>>15427479
The SSPP numbers include the supporting structural mass in their calculations. The mass of the entire spacecraft in this example is dominated by the array mass, it would be 200 tons. 10,000 W/kg would bring it down to only 20 tons if it needed the same amount of power, which it wouldn't.

>From Earth’s sphere of influence, the 200 MW Mars transit would take approximately 39 days an use 203,000 kg of propellant with the Isp varying to minimize the mass of the propellant used. Once the spacecraft arrives at Mars, it will be travelling at a relative velocity of 6.8 km/s at which point the crew service module would detach from the main spacecraft and descend to the surface using an indentical entry profile to the Mars DRM. After separation, the main spacecraft will dump empty tanks and will continue passed Mars switching to a high Isp mode of operation. After the 36 days and 10,000 kg of propellant, the spacecraft returns to Mars and the crew returns to the spacecraft for the return flight. For the 200 MW mission, the maximum thrust achieved by the VASIMR is 7.14 kN at a specific impulse of 4000 seconds.

I don't think you understand how wild it is to reach Mars in 39 days with electric propulsion or what it would mean for other planets which are substantially harder to reach as the dV required for just a basic Hohmann transfer pushes the limits of chemical propulsion. This would only benefit in that instance, it wouldn't need to accelerate as rapidly, the power requirement would drop significantly, it would gain more dV or payload. The result would be years being cut from the length of the trip.
>>15427664
You want fuel commonality, you want it to carry around 100t of propellant, and you want to maximize the amount of volume left over for payload. Any hydrolox stage is out of the question but Centaur III does technically fit.

Proof but keep in mind that the propellant mass is only 21 tons. Not sure if Centaur V would fit but you're still no where close to what a methalox stage would be and you can use the Raptor engine.
>>15427680
No one is saying this is a replacement for chemical Mars architectures to set up the colony but there is the eventual need to decrease transit time under some circumstances to less than 3 months/500 - 1000 day long mission in total and gain the ability to do it outside of a transfer window, like if they needed to send emergency supplies or evacuate.

The thing is that one of their reference missions would use a conjunction transfer but they're just flat-out ignoring the possibility of spending more than 30 days on the surface. I don't have a rock solid explanation for this, one idea is that they think congress would favor a flags and footprints mission so they don't have to invest anything in a colony, but it might just have to do with old space lobbying hard for nuclear thermal which looks slightly less shit when applied to higher dV missions and the gazillion launches to bring up LH2 tanks to Lunar Distance High Earth Orbit would line many pockets.

Still, it's hard to take any of this seriously when you look at the launch date...

Most interplanetary probes don't depart from LEO, it's expected that they get put on to an escape trajectory or close to it. You could stop in LEO, open up the clamshell, configure the payload to where everything is extended, then burn the rest of Starship's propellant but the probe would have to be designed to withstand the forces of this and it may mass higher than just designing a more reliable deployment mechanism. You can come up with exceptions to this, sure, like if you launch a large probe or tug that uses electric propulsion and it has the dV to spiral out under its own power over months and still complete the rest of the mission. You could also keep someone in a higher orbit if a payload has to be adjusted but this gets tricky with all the different inclinations that would be used and of course the cost.

I'm sure someone will come up with a drone like robot that stays with the probe over the entire mission and can fix small issues plus do inspections, that's more realistic.

You're thinking too dramatically. Satellites are and will be extremely important to warfare and it makes sense to have one military branch overseeing them, as opposed to the dozens of agencies which preceded the USSF in that capacity.
>There are no legitimate threats in space
Yet. Once any actor opts to militarize space then everyone will and having the infrastructure and theory in place to compete already in place is extremely beneficial. Spending a few years scrambling a new branch, budget, and officer corp together is far from ideal when those years actually matter. Also note that China and Russia were both ahead of the US in this regard.

I'm not against the USSF as a mere organization, I'm against the idea that they will or should do anything besides manage satellites and that there is some great lingering threat against US space assets, let alone a threat to actual humans. ASATs are just not effective as a weapon, you take out a few satellites and in return you get every other government breathing down your neck wondering why you're creating a bunch of debris impacting their assets and their economy. They cannot counter constellations, like Russia for example wouldn't be able to take down Starlink or the military version of it and of course there is no stealing satellites because everything the size of a pebble can be tracked and we have other forms of counter surveillance besides radar.

All the LARPing that gets done is pointless and may provoke a real space war which would be bad for everyone besides the military-industrial complex, I see no reason to kowtow to a bunch of desk jockeys in Startrek knockoff uniforms, most of which have less understanding of space than a 12 year old that has played KSP for a few hours.

A6 is just a slightly cheaper A5, and they've been pussyfooting around the idea of reuse for so long it's almost more of a surprise to hear they actually had NOT given up on it already.

Diamonds and other gemstones are essentially worthless. Theres so many cheap synthetic diamonds in circulation that you cant tell the difference between that even De Beers monopoly on their own artificially inflated price trade is being slowly toppled. The only reason that diamonds are even considered valuable is because of De Beers over a century of advertising them as such and creating dumb reasons to buy them that people fall for i.e. a worthless but shiny rock on a ring costing tens of thousands. If you flood the market with cheap real diamonds, it will only devalue them further (like synthetic diamonds have been doing). Needless to say, space is filled to the brim with resources that would be considered rare on earth. The laws of supply and demand apply, and like how De Beers has been doing by controlling how much of their enormously massive stockpile they sell to not devalue what they have, the same would have to be applied to anything taken from space as to not devalue it, however that is difficult with most resources that you would find and the sheer quantity. It also costs allot to transport these materials, so you have to weigh whether it is worth it to completely devalue the material you plan to sell by flooding the market as well as it costing a fortune to ship. This is in general why nothing in space is profitable other than LEO satellites and selling tickets.

Chemical engine performance has reached its upper limit, something that could surpass Starship would probably use some type of new material that greatly reduces structure mass or just be a much larger version of it but it's diminishing returns as the payload mass starts to dwarf the rest of the dry mass.

Apollo was extremely expensive. The costs of it were known, and there did not appear to be any means to significantly cutback on the cost of the vehicle. Simultaneously, the government had made it well known that NASA's budget was going to be scaled back greatly. Thus, NASA could not see a means to continue the space program with Saturn V as the main launch vehicle due to low launch rate and high costs that would only be exacerbated under cost cutting. Consequently, the notion of lunar bases, and Mars bases, and so on were completely abandoned as Saturn (and its future died). NASA then needed a new, reliable launch vehicle to replace Saturn and allow them to achieve certain scientific programs. From this desire the STS was developed in conjunction with funding from the Air Force so long as certain design considerations were implemented. NASA could not turn their nose up at this offer of joint funding. Further, the expectation was that STS would be far cheaper than the Saturn program in terms of fly away costs, and the time between launches would be greatly cutdown by having several launch vehicles and refurbishment taking little time and little cost.

Virtually none of this came to be, but it is what they believed would be at the time.

So after you spent billions of dollars creating this monstrosity, manufacturing a bunch of unnecessary tanks, revamping the SpaceX pad infrastructure for hydrogen, launching SLS five times, launching Starship 20 times, you get 2x20 tons of cargo landed on Mars, plus whatever is carried in the manned lander. Starship with something like five or six refills can land 150 tons on Mars. It's incomparable, Starship is literally designed to land large amounts of payload and crew on Mars quickly, cheaply, and effectively. It has a lower delta-v requirement for the mission because it can aerobrake and there are no other landers necessary.

Anyone that supports NTP Mars missions is either completely fucking retarded or a shill. Take your pick.

Nigger, the Aerojet proposal requires ISRU oxidizer production for the MAV. If ISRU methane was impossible(it's not and your speculation is retarded), SpaceX would only need to drop off ~200t to get home so they're still well under the 20 launches.

Scheduled to launch on a SpaceX Falcon 9 rocket to low-Earth orbit no earlier than August 2025, Haven-1 will initially act as an independent crewed space station prior to being connected as a module to a larger Vast space station currently in development. The mission will be quickly followed by Vast-1, the first human spaceflight mission to Haven-1 on a SpaceX Dragon spacecraft. The vehicle and its four-person crew will dock with Haven-1 for up to 30 days while orbiting Earth. Vast also secured an option with SpaceX for an additional human spaceflight mission to Haven-1.
