>>12935021Shit on the ISS all you want but it’s not like NASA could’ve gone to the moon or Mars. There wasn’t the money or political will. Actually maybe there was money but extending an olive branch to Russia was way higher up on politicians’ totem poles. It’s not perfect but it’s better than nothing. And it gave us SpaceX. Reusable rockets operated by the government are doomed to fail because government organizations are retarded
http://www.projectrho.com/public_html/rocket/enginelist2.php A single stage system I described previously, with one crewman and five passengers seated in a capsule beneath a 30 cubic meter propellant tank, would mass 1,585 kg and carry 30,000 kg of water salted with 6LiD (mass ratio of 19.9), passing through a high neutron flux region to produce controlled thrust. With a 4,700 km/sec exhaust speed, the vehicle is capable of achieving (a delta-V of) 14,062.86 km/sec! Enough for a one gee boost of 16.6 days!! With 4 days of boost combined with 4 days of slowing down the ship can cruise at one gee a distance of 1,171.28 million km (torchship brachistochrone trajectory). This is sufficient to fly to any celestial body out to Jupiter and back. Reducing acceleration after planetary escape to 0.416 gees increases boost time to 10 days per leg, 40 days per round trip, and increases range to 6,075.15 million km. This is sufficient to take us to all celestial bodies in the solar system, including Pluto, Haumea, Makemake, and Eris.
Didn't the ISS also show the effects of micro meteorites hitting a space station?
>>12935031I was shitting on the ISS in the last thread but I completely agree with this assessment
>>129350362 days to mars1 week to jupiter1 month to neptunethis is the key to the solar system why isnt anyone funding this?
>>12935031The ISS is a cool thing to have around no doubt. It's just the insistence by that one anon that everything being done on it is important and groundbreaking that I find strange. It's just a research lab at the end of the day
>>12935058>1 moonNASA thought this was clever enough to put on an official poster
>>12935052I never said *everything* being done is important and groundbreaking. I was pushing back on the fiction that the *only* benefit has been the effects of micro gravity on the human body. So experiments have definitely been duds or not super useful, but they haven't been doing "high schooler experiments" like the one normalfag anon said.
>>12935021the star custer passing by is kino
>>12935070A lot of important science is done on the ISS like atmospheric studies and inflatable habitats and long-term survivability of space-based habitats.
>>12935031The only realistic option that might have been better than the ISS would have been some sort of joint US-Russian mission to the moon but even though that might have happened between 1990 and 2010 it would have been a tall fucking order because we had these big fancy space shuttles but nothing for them to shuttle to other than Mir.Like, I'm imagining something like the Artemis mission profile only the Gateway station is a Mir core block that's pushed into TLI by some sort of TKS-based tug stage and it's used as a base for an American-built lander that resembles a better HLS built by Lockheed or Grumman that's launched in the shuttle payload bay and after a rendezvous with a previously launched American tug stage pushes itself to the Gateway station and the Astronauts ride to the station in a modified Soyuz launched on top of Proton while fuel and supplies are launched on an ESA ATV style ferry that's launched into LEO by the shuttle.
>>12935031>>12935038its amazing how much using the exact same amount of money but in an organized way can yield much better results. The SHUTTLE+ISS+SLS budget basically amounts to shit so far, none of it resulted in america having good access to space.Yet if you had taken that same amount of money it would have been more than enough to fund another "exactly as is" apollo program.The issue is that the money would have had to be used centrally.Central planning is the real difference. Its really just like healthcare. If you pay 0.01 cents for the chance to use a complex health machine if you need it then its much more profitable for the whole, like you wouldnt have caused 1 billion dollars of wear to machines, but if the machine doesnt exist a private person without the help of a care system doesnt have much choice but paying for it EXCLUSIVELY for him which would make it insanely more expensive.its all a matter of organization and central planning and a great argument in favour of communism. The ironic side of things is that in current capitalism this case the state is actually the one who promotes senseless disorganized spending made by many private actors (old space) and a private company (spacex) is the one who is providing a centrally planned coherent plan.Also, during the cold war the us won by being as communistic (centrally planed) as possible, and the USSR tried to fight back by being as capitalistic (distributing power to free agents so that they achieved good results via their interaction) as possible
>>12935078>important science>inflatable habitatsTime to stop memeing.

>>12935081>The only realistic option that might have been better than the ISS would have been some sort of joint US-Russian mission to the moon but even though that might have happened between 1990 and 2010 it would have been a tall fucking order because we had these big fancy space shuttles but nothing for them to shuttle to other than Mir.>Like, I'm imagining something like the Artemis mission profile only the Gateway station is a Mir core block that's pushed into TLI by some sort of TKS-based tug stage and it's used as a base for an American-built lander that resembles a better HLS built by Lockheed or Grumman that's launched in the shuttle payload bay and after a rendezvous with a previously launched American tug stage pushes itself to the Gateway station and the Astronauts ride to the station in a modified Soyuz launched on top of Proton while fuel and supplies are launched on an ESA ATV style ferry that's launched into LEO by the shuttle.going to the moon is very easy. you just do an on orbit assembly of a lunar craft, use soyuz rockets, super reliable relatively cheap and man rated.It would be cheap enough that it could be done if needed. Like, probably tyhe whole mission for less than one billion dollars or about that much. But its too expensive to do it "just because"
>>12935058>2 billion dollars per launchWhy do they include this figure on their advertising material as if it's something cool or admirable? They should be utterly ashamed of themselves for wasting so much money on that useless heap of shit.
>>12935047>this is the key to the solar system why isnt anyone funding this?it requires weapons grade uranium, if anybody will build it first it'll either be russia/china or an independent space colony, not the use
>>12935101>Why do they include this figure on their advertising material as if it's something cool or admirable?it says 0 chance of succes, its obviously a joke. Like, are you an american of average intelligence or are you considered gifted?
>>12935098Yeah exactly, I'm imagining that an Artemis mission profile joint mission to the moon probably costs a fraction of what the ISS does and seems very doable by 2005 or so if you start from 1994.The moon was still old hat back then and I think NASA felt legitimately mogged by the Salyuts and Mir and wanted a spess steshun of their own so that it could be US astronauts setting on-orbit endurance records again.
I just think its neat
There is no scientific possibility of traveling to other planets.
>>12935070>I was pushing back on the fiction that the *only* benefit has been the effects of micro gravity on the human body.To be fair that is the only tangible benefit as far as spaceflight is concerned. Protein growth and the like is too niche to care about and things like maintaining and repairing a space habitat would have inevitably been figured out with or without the ISS. Ultimately the ISS is a boring place where boring science is done. And there's nothing wrong with that
>>12935118The truth is that boots on the moon was something feasible, if needed since, well, since we went to the moon. "lol guys it would be so cool" just isnt a good reason to go, for that price at least. With starships levels of price then yes, just because becomes an option
https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=914>The objective of the REBR flight test is to verify the use of a small, lightweight, autonomous system for recording temperatures, accelerations, and other data experienced by the host vehicle during reentry, surviving the breakup of the host vehicle, and finally “phoning home” the recorded data prior to impact of the recording device.This is neat, wonder if SpaceX uses something like this on starlink or for the upcoming re-entry tests for starship
>>12935124>To be fair that is the only tangible benefit as far as spaceflight is concerned.???????Water purification?In space construction?Radiation shielding?Urine processing?Detecting loss of pressurization?Why do so many /sfg/ anons have such a surface level understanding of space flight?
>>12935118>and I think NASA felt legitimately mogged by the Salyuts and Mir and wanted a spess steshun of their ownThere also existed a culture at NASA since the 60's that were salty at Apollo because in the natural order of things building a large space station happened before going to the Moon. After Apollo 11 pretty much all future planning revolved around building a large Space Station to get manned spaceflight "back on track"
>>12935132A robust black box that can survive reentry sounds like a very useful thing to have.
>>12935139None of those things are reliant on the ISS specifically to accomplish and many of them had already been accomplished before at places like Mir
>>12935139All of that was proven before the ISS even existed. Why do so many people think it was the first space station?
>>12935139>>12935070a little principle of science states taht you should only do experiments for those things for which you have reasonable reasons to believe they wont be different from models.Why not do an experiment to see if rockets work in space?, how about further to the right, how about further to the left? if you havent tested rockets, radio waves, and every single law of physic in every single cubic cm of the universe how can you know it works, right?wrongultra retarded, all "science benefits" are for things that we already kew 100% how it worked, and most of it worked almost exactly as predicted because theres no science going on there, thats not the main driving force behind it. The main driving force is rocket-geopolitics, and all science comes after as justification. And its all the same for them, because retards like you (90% of the populatino who believe the us flag deserves respect and that conspiracy theories are conspiracy theories) cant see the difference between the two
>>12935139why do you list things that were specifically 0% advancedc on the iss. like do you hate yourself?do you have an intense fetish on being wrong and so stupid in a way that if it not were anonymous you could not get a girl to be in the same room with you if you were anywhere wehre the rumors of how stupid you are arrived?
>>12935153>>12935152The ISS allowed for improvements and standardization. Also Mir did not test water purification or urine processing, the russian side of the ISS still does not have this technology. Also, Mir really didn't test radiation shielding other then noticing that more mass = less radiation
>>12935064you thought your reply was clever enough to post a second time
>>12935081This could’ve happened but why go to the moon to work with the Russians when you could do the same in LEO? That’s how politicians think. Also NASA was retarded at the time and thought that going to the moon again required 6 million shuttle flights and required a big add station in LEO check it out>https://history.nasa.gov/90_day_study.pdf
>>12935158>Why not do an experiment to see if rockets work in space?Uhhh, this was an experiment. Not necessarily to see if they work, but to collect modeling information on plumes and exhausts (Important when firing rockets near a space station)This is exactly what I mean by a child's understanding of science. This isn't KSP where you just check a box then you are "done" with the science. There are always things you can do to improve your understanding, which can be leveraged during alter projects.
>>12935171Mir was gross as shit lol it was the traphouse of space stations
>>12935183>This is exactly what I mean by a child's understanding of science.so basically project what people say about you back?yep, you sure are childish op.if you think experiments on rocket plumes are vital in 2020 and not and after the fact justification of why they are there, then HOLY FUCK dont consider a career in science if youre above 12 YO
>>12935171>Paying billions for people to drink purified piss when you could have done it on Earth for a few hundred with simple filters that don't require gravity.

>>12935191>if you think experiments on rocket plumes are vital in 2020Because we already conducted them on the ISS. https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=275This not only got us modelling data, but a potential anti-sat weaponhttps://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=399>Artificially created plasma turbulence can disrupt military navigation and communications using radio systems. Now seethe like the normalfag you are
>>12935124>boring scienceA lot of it is too obscure for people outside the specific field to understand. For example there were studies of combustion and chemical kinetics in general because in microgravity there's no convection that normally drowns out the subtle details in experiments. The results were then used to better understand and optimize the relevant processes back on Earth.

>>12935191>if you think experiments on rocket plumes are vital in 2020 and not and after the fact justification of why they are there, then HOLY FUCK dont consider a career in science if youre above 12 YOIf you are too stupid to understand that rocket plumes can adversely effect sensitive hardware, YOU are the one who should consider a different career.

>>12935340>”In 1998, U.S. astronauts participating in the NASA 6 and NASA 7 visits to Mir collected environmental samples from air and surfaces in Mir's control center, dining area, sleeping quarters, hygiene facilities, exercise equipment, and scientific equipment. Imagine their surprise when they opened a rarely-accessed service panel in Mir's Kvant-2 Module and discovered a large free-floating mass of water. "According to the astronauts' eyewitness reports, the globule was nearly the size of a basketball," Ott said.”>” Nor was the water clean: two samples were brownish and a third was cloudy white. Behind the panels the temperature was toasty warm—82ºF (28ºC)—just right for growing all kinds of microbeasties. Indeed, samples extracted from the globules by syringes and returned to Earth for analysis contained several dozen species of bacteria and fungi, plus some protozoa, dust mites, and possibly spirochetes.”

>>12935367>if you blow into a balloon really fast it will become empty
>>12935383Holy shit what was Russia thinking?
>>12935395Honestly most of the problems with Mir could have been solved with an internal "remodel" with better ventilation and more compact/organized electronics.
>>12935203>cute astronaut who did Janeway cosplay in the ISS cupola drinking coffeeA big part of why we need a permanent manned presence beyond LEO is that so much of the scifi that inspired earlier generations is now trash, because we know space does not work that way. That means we need REAL achievements to inspire the young now.

>>12935423>Dark energy seems to be constantIts more or less a different way of looking at it. You can say dark energy is increasing relative to others in space or that dark energy is constant but the rest of the universe is spreading apart increasingly. IMO instead of big rip, there will be lot of little rips that will create islands of universes/galaxies/solar systems/etc which will later be absorbed into the dark energy state as the expansion of space increases/matters decay into constituent particles/etc. Like bubble wraps that get popped and flatten out.

>>12935717it is true that having a convential explosion of any kind or a nuclear explosion inside your ship would not have any significant difference in the end result regarding hte lives of crew
>>12935717It's very different actually, in a NSWR engine you need to manage gamma ray and neutron heating, so while you can use a curtain of water to shield your engine from direct exposure to the hot nuclear plasma, you actually also need a labyrinthine cooling system flowing water across EVERY solid part within a certain radius of the center of the nuclear fission region of the engine, because otherwise those solid bits will rapidly melt and vaporize as they're pounded by high energy ionizing radiation.
>>12935717>>12935726>>12935729The crazy part about NWSR is not the engine operation, it's the fuel. In an Orion drive you're powered by nukes, which as we all know don't go off unless you want them to, even if the vehicle crashes or whatever. The NSWR on the other hand is powered by uranium/plutonium salts dissolved to the point of saturation in water, which requires a tank filled with an open cell foam made of boron or some other highly neutron absorbing material, because if too much of that salty water solution collects in one place with no shielding to beat down the chain reaction, the fuel will self-detonate. This means if your NSWR develops a leak ANYWHERE in the system, there's a good chance that water will either collect into a critical mass somewhere or will continuously boil off in vacuum and leave a bigger and bigger clump of uranium salts at the point of the leak, until that mass approaches criticality also and ends up flashing into plasma at some point, blasting a hole in your vehicle in either case and likely setting off the rest of the fuel too. It's like this: Orion drive is a vehicle powered by many small nukes which only detonate if you tell them to. NSWR is a vehicle powered by what is potentially one giant nuclear bomb, which could go off at any moment if something went wrong.
>>12935696>>12935690weren't those two demo satellites?

>>12935744Jesus.... no wonder development has been slow or even non-existent,
>>12935750Yes, the sky is colored because of light scattering off dust, so if the ground is redder or yellower and the dust is scattering that light back to the camera, you will see the color of the ground reflected in the sky.

>>12935764>I have no idea though, but if they are in the game they'd probably be very late game tech.Why would they be late game tech when the game is focused on interstellar travel? I imagine they'd be mid game tech, and that late game tech would be stuff like anti-matter propulsion.

>>12935859Behold! A Falcon 9 first stage!
>>12935856Am I the only person who liked the Ares architecture? Imagine if Ares/Orion and SLS had been developed in parallel. "short" Ares with a smaller/lighter Orion capsule with a better launch escape system to avoid the parachute burnthrough risk, and SLS as a strictly heavy lift vehicle to avoid the extra cost of man-rating it.
>>12935881I like Ares I.
>>12935883I wish it didn't have a hydromeme upper stage but I honestly think it was the better option.
>>12935856also, make sure more than 50% of people shown are not whitemake sure females are shown at least 50% of the timethe first or last person shown cannot be a white man
>>12935856Is it bad that I just now realized that the big orange upper part isn't the payload? I really thought the SRB was the only thruster it had.
>>12935771>>metallic hydrogen engines>First, could you elaborate on that?Metallic hydrogen engines, decomposition of metallic hydrogen into diatomic hydrogen liberates some retarded large amount of energy per mol, way higher than any conventional chemical reaction, and the density is not horrific either. Total meme at the moment because we have no way of making metallic hydrogen and it's not likely to be metastable anyway (probably impossible to store and feed through an engine). However ksp is a game so why not.>Second, if they have this meme shit they better have other actual meme shitThey basically have a kerbalized version of all the big future propulsion concepts you can pull out of hard scifi, from what I can tell.
>>12935881It would have been neat if they developed Orion to launch on Atlas V or Delta IV Heavy and then kept Ares V for it's intended purpose to launch cargo elements. Who knows, they might have had Orion actually launching crew in a timely manner if they didn't try go out of their way to over-design it to justify Ares 1
>>12935772>>12935772>Why would they be late game techBecause while NSWR is not the best in terms of Isp compared to something like a matter-antimatter rocket or some other ultra high energy physics shit, NSWR has the advantage of massive THROOOST. Almost any super efficient propulsion system is physically limited to having a tiny thrust output because even at 99.99% efficiency, that remaining 0.01% of energy being absorbed by the spacecraft as waste heat becomes impossible to manage if you're trying to dial the thrust up to kilonewtons when your exhaust velocity is tens of thousands of km/s. Basically the kinetic energy of your own exhaust becomes so extreme that even being near it will melt your vehicle, so you need to only make so much mass of exhaust per unit time, and since thrust correlates more strongly to mass flow rate than exhaust velocity, the net result is that higher Isp systems can't get as much thrust force as lower Isp systems, even though they can sustain that lower thrust for a longer time, proportionally. Blah blah. Having a rocket engine with an Isp of 80,000 and a thrust in the giganewton range makes all interplanetary travel so trivial that it wouldn't make game balancing sense to have it unlocked before you could go interstellar, which is a mission profile that requires very high Isp systems (thrust not mattering as much). For game reasons it makes sense to go from orion drives to daedalus engines and then antimatter thrusters and NSWR.
>>12935894SSTO on a shuttle SRB is possible with a Gemini-sized vehicle but it would be one hell of a ride.

>>12935915lmao how'd they manage to do that it was protected by a dust cover, and underneath the rover for so long
>>12935915seriously though why not make the rotors out of solar panels, that way not only do you eliminate the flat panel on top (which may be complicating the flow dynamics) and maybe save mass, you'd also clean your panels with every flight due to the high rpm spinning and high dynamic pressure during flights.
>>12935933probably can't get the necessary aerodynamic shape and working solar cells in a single structure
>>12935920Nothing mechanical has ever failed due to Mars dust, you're thinking of Moon dust maybe. Also just fyi, one of the big reasons Moon dust is so bad is not actually due to being abrasive, it's due to being very hard, which means virtually all passive oxide layers will be eroded by contacting it, which means anything mechanical you send to the Moon will quickly start having lots of cold-welding related problems if you aren't careful about keeping similar alloys and base metals apart from contact with one another.

>>12936039Well in theory it is designed to be launched from the Vulcan, Delta-IV, Atlas-V and Falcon 9 rockets.Fun fact: Boing never did a midflight abort test with Starliner so we dont know what will happen should one of the various types of rockets underneath the capsule pull a Soyuz MS10.
>>12935973Any debris that hits the vehicle will be vaporized by the impact before it traveled its own diameter. Not only would a thin layer of foam be sufficient to stop any tiny impactors like that, anything big enough to actually poke a hole in the capsule would have the effect of blowing up a tiny amount of high explosive on the inside wall of the vehicle (that is to say, the occupants would be sprayed by high velocity gas and dust, and apart from hearing damage would be fine).

>>12935988Commutators are a widespread and well understood kind of electrical connection with a long history in engineering. They are electrical components that spin along with a rotator and conduct current via a physical connection to a non-rotating object called a brush. These can be actual metal brushes, solid blocks of metal, or most commonly spring-loaded blocks of conductive graphite. The lattermost option is self lubricating and due to the softness of graphite is almost guaranteed to always make a strong electrical connection to the rotor. If I were designing a Mars helicopter with rotor solar panels I'd use two slip rings and several brushes per slip ring to maximize the contact area and guarantee a long mechanical lifetime from the connections.

>>12936113The dome is likely the most sensitive bit of that spacecraft for impacts, yes. As for spall, I dunno. I feel like polycarbonate is soft enough that rather than spalling like a plate of strong metal would, the poly would at more like ballistics gel and have a blobby crater blown in it without transferring much force to the interior surface. This is one area in which a plastic dome makes a lot of sense for this 'mission'. That and also the reduced crack propagation tendency due to not being as hard as plastic, which likely overcomes the need for laminations. Oh also, the fact that this thing isn't gonna stay up for years means that any concerns about the effects of ionizing radiation cooking that plastic aren't an issue.

>>12936158Those station modules aren't design for perpetual mantainence. Even in some of the relatively young iss modules the wear and tear starts to show. If they had tried to keep a "continuous" not they would have eventually had to replace the whole thing module by module or suffered a major catastrophe
>>12935886>I wish it didn't have a hydromeme upper stageGiven the engines that existed even on paper at the time the J-2X was the best choice.
>>12936174In case of the Mir station, use several bottles of mold remover
>>12936141>It's a technology demonstratorI know, but in the future if they're gonna go anywhere with this technology it would be nice to not have to fuck around with dusty solar panels and accidentally have the probe freeze and die because it happened to land in an especially dusty area and couldn't get its battery charged enough in time for the freezing night. Again it's not about saving weight, it's about minimizing panel effectiveness losses.>>12936147>obviously didn't look it upIt's the same tech as is inside any electric power tool you've ever used or seen, you have a stationary conducting 'brush' making contact with a rotating conducting 'slip ring', and you design both to minimize friction and maximize contact area/conductivity. These things are used literally everywhere. The alternator inside of your car uses this technology. It's not complex or difficult. It just requires smart materials choices. Again, graphite brushes are king in this application for the most part because they are self lubricating and also have zero risk of galling or cold welding or anything like that. In fact Ingenuity itself may be using a motor with brushes, because it eliminates the need for any permanent magnets, which would act as a trap for any magnetite dust and could fail very quickly (also permanent magnets are more massive per the field they produce than electromagnets)didn't realize the thing had such a nice camera btw
>>12936174With Mir it would've involved removing and replacing experiment racks and some of the life support system. Mir's biggest problems were storage and ventilation. Both of which could've been solved with updates. As far as I understand, the actual modules were healthy. I'm also a big fan of the "station of Theseus" idea where you just continually add new modules and deorbit old ones.

>>12936169https://www.antarctica.gov.au/news/2010/33rd-antarctic-treaty-consultative-meeting/Interesting design.I mean you can think, whatever you want. The point is space was militarized from the start. And the nations aren’t really opposed. At least not the big ones. They know each other. If you look closely all the footage is either inclusive or CGI. Many people for example think they build the Saturn 5 rocket, when in reality they didn’t and nasa just contracted an insane amount of companies. Why did they do it? Because they wanted people to think it has to be real, since everybody knew somebody, who knew somebody, who worked on the program. Same goes for the people in the control room they admitted on camera they couldn’t tell a difference from the training. We caught them with harnesses, we caught them dropping things in zero g. We caught the ends of the zero g plane flights. We caught the CGI glitches. We have somebody, who manufactured globe images on record admitting it. Few people have to know it. It’s all compartmentalized and most just know a little piece. Also look at Werner von Brauns grave. Interesting last words he chose.

Anybody remembers when New Horizons launched? I was all excited about Pluto, because the blurry monochrome pictures were so mysterious, it took a decade to get there. Feels like yesterday. I feel like the recent space sector developments have me a lot more impatient.
>>12936192>>12936174Yeah remodeling either ISS or MIR would basically be impossible and also not worth it.However, next gen space stations don't need to be so limited by mass optimization autism, which means we could have a chance to build a new station that could actually be practically maintained for a few decades before needing any major work. I'm talking about launching station modules that consist of dome-and-barrel tanks made of inch thick steel, with a docking adapter at either end and exterior hardpoints in a consistent pattern across the exterior and interior surfaces. Once in orbit the modules are joined together both by the docking adapters and by simple metal bar struts connecting hardpoints across the docking interface. External services are installed outside on hard points (electrical generation, waste heat radiators etc), internal services are installed on hard points inside (power supply ports passing through the docking adapters keep the life support and so forth running). The exterior is wrapped in insulating blankets and the inside is padded with foam sheets where applicable. You now have a space station built like a hybrid between a submarine and an antarctic research station, you can add modules at will and you can gut old hardware out of existing modules to replace it at any time. The main hulls of each module are made of thick steel in order to ensure any loads are so far under the fatigue limit of the material that cracks will never form even after centuries of hot-cold load cycling. Also you can easily weld with steel and with such thick material you have no risk of accidentally popping one of the modules while welding something onto the outside.

>>12936284I dunno bro I think having a central hub for experiments, power and life support is better then building a new probe each time.
>>12936277In any kind of even halfway realistic design that thing would vaporize itself before it even reached full thrust, due to the gamma ray flux coming out of those matter antimatter reaction chambers at those thrust levels (I think those ships were capable of pulling more than 1G or something insane like that). If the design was meant to accelerate for years then flip and decelerate for arrival, and therefore had orders of magnitude less thrust and gamma ray flux, then they'd work fine. I think anything similar (annihilation torch) in Ksp2 is gonna be of the low thrust for a long time variety, like the current ion drive is except bigger and way more efficient. One of the things they're adding is time acceleration while burning, so it's not like the low thrust will hurt gameplay THAT much.

After the mission they can actually refurbish and repair the vehicles as necessary before the next launch, getting them totally fresh and ready to go. 6 fully bought and paid for SpaceLab Starships would cost less than a single ISS module.
>>12936284Nah there is some neat work being done on the ISS. Whether or not that justifies its exorbitant price tag is up for debate but it's nice to have a destination in LEO for spacecraft to go to

>>12936300IIRC James Cameron actually considered the problem of gamma ray flux and explained it away as being that the engines were built from exotic materials building off of human experience with commercial fusion reactors since it was like the year 2200 and fusion was pretty commonplace by then. I think that Cameron also estimated that each of the Interstellar Vessels would have cost over a trillion dollars in 2009 money to build apiece.But yeah the official line was that the big ship accelerated at 1.5G for months on end to reach a double digit percentage of C. I think it also used orbital laser arrays and a hyper-efficient reflective sail for the departure and return burns out of and back into our solar system, only using the antimatter drive on the Alpha Centauri end of the trip. Like something out of a Larry Niven novel, I'm amazed that it made it on screen.Speaking of Niven, I really really really hope that the sequels explore the Kzinti implications of a 100,000 ton spacecraft that can accelerate itself to a double digit percentage of C. Even the laser array that could do that is some IRL death star shit. Apparently the accompanying materials stated that the ship was supposed to throw out an exhaust plume that was brighter than a welding arc and over 100 miles long and described as "the most spectacular occurrence either natural or artificial that had ever been witnessed by human eyes" and that the colonists on Pandora looked for the exhaust plume of an incoming ISV in the night sky like a man-made comet. I think the film was actually supposed to show that in a scene that ended up getting cut. Maybe they'll show one being used as an RKV in the sequels.

Opinion on this little text?>The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age.

>>12936526It's basically Lovecraft predicting Tay's Law. The minute you give an AI enough data to really solve a problem you run the risk of it flatly declaring the rules of your society incorrect, whether that's the claim that races are equal or the rules of celestial mechanics. So far the people running the AIs have chosen the dark age option by deliberately crippling them - Google couldn't stop its image tagging AI from classifying blacks as gorillas so it just stopped the AI from labeling anything as a gorilla at all.

>>12936526The concept of our simple mind being overcome with the vast, limitless, overwhelming forbidden, unknown knowledge is an appealing, repeating notion through history and fiction. I like it.

>>12936594I guess the whole fairing catching thing didn't work out. So they're trading in two boats for one bigger one that just scoops them out of the water. Pic related
>>12936509>>12936538>>12936577Bummer, I just ran the calculations and apparently a 100000000kg spacecraft traveling at 0.7C is only about half the kinetic energy of the Chixulub impact, which was estimated to be an asteroid with a mass of ~1.8x10^26 kgs travelling at 20 km/s. So not a planet killer, just a dinosaur killer.
>>12936615I'm reading some claims that pic related isn't permanent. We'll see.
Is space sex better than regular sex?
So Ive been doing some math and this is pretty much the best way to make superfast spaceships.>get spacecraft and counterweight with ion thrusters to orbit>connect them with several km long tether>tether also has a small tube for gas> fire up spaceship and counterweight ion engines>keep pumping gas for ion thrusters through a hub at center of rotation>cut tether precisely when speed is enough>profit?
>>12936642Nobody has described it to my knowledge, although I'm sure it's happened at least once. Probably awkward in null-G, but who knows, the uniqueness might make up for it. Certainly at least you don't have to worry about crushing your partner in any circumstance, since neither of you will have significant weight.
>>12936648Why not just use drop tanks though? Whether you spend a week accelerating in LEO or a week accelerating after leaving LEO, you can still spend the same week accelerating and you don't have to complexify your spacecraft or add the extra mass of a counterweight that will necessarily weight quite a lot all on it's own.

>>12936838It stemmed from concerns by Heisenberg and later Oppenheimer that due to the inherently unstable nature of Hydrogen and Nitrogen in the air and water, the temperatures and pressures of an atomically catalyzed explosion might be sufficient to give rise to a self-sustaining fusion chain reaction. I think in hindsight though, it should have been obvious to everyone involved that the concentrations of hydrogen in our atmosphere or oceans, and the fact that most all of it is paired up into water, and furthermore just how efficient fluids are at absorbing and dispersing energy through much larger volumes, would make it impossible to ignite spontaneous fusion in the open air on Earth. I think they let the anxiety they must surely have been feeling about the very real capabilities and potential of the bomb drive them to irrational conclusions about worst case scenarios.

>>12937151>>12937344so to summarize, the French Space Agency thinks that...>Sending humans to Mars is not for science. You'd only do it for glory>Using Mars to guarantee the existence of human consciousness is dumb >Humans don't do better than robots>ESA has zero ambition to compete with the rest of the world>Musk is a "complete mess">colonizing Mars is unethical>BFR and the Raptor will never happen because Musk NEEDS NASA to cover the bill (???)>to land people on Mars you can't just aerobrake>To return you need to fly past Venus which is bad because it's hot (?????????)>Zubrin's Mars idea is full of shit>we can't land accurately on Mars>Humans on Mars in the 2050s>>12937407brutal but probably true
>>12937444It's ESA so they have lower radiation limits than NASA and aren't willing to send people on one way colony boats like SpaceX.
>>12937296We can build rockets?
>>12937296I didn't know we had our own rocket startup here. >it's yet another smallsat launcherIt won't see past 2025, will it?Fucking dumb cunts in Canberra should loosen up aerospace testing regulations and offer massive tax incentives for SpaceX to open up a Starship manufacturing plant here. They could build them using steel from Whyalla or Port Kembla, and then launch Starships from either Woomera or somewhere off the east coast.If SpaceX are wanting to build 1000 of the bastards and have a million people on Mars, then they'll need to expand. This could be a massive opportunity to help boost the Australian economy. But of course, the Australian federal government sees banking and housing as the only industries worth protecting while they sell us out to the chinks. Bunch of cunts.
>>12937435SWITCH YOUR PEOPLE OVER TO REFURBISHMENTIF YOU INCREASE CADENCE ENOUGH YOU COULD HIRE EVEN *MORE* PEOPLEJFCalso he has a lot of confidence in reusability if you're only making 1 booster a year. They blow up from time to time
>>12937151>>12937344>>12937454Suddenly even Artemis looks bold and revolutionary by comparison. This is abhorrent. No wonder his type wants the Great Rebunga, they couldn't innovate their way out of a paper bag and can tell they're losing power.
>>12937470I'm suddenly feeling a lot better about the SLS.
>>12937296>>12937461>https://www.gspacetech.com/launchAnother smallsat. Due next year.>https://youtu.be/M4fIrbpqTowoh cool they're using hybrid engines.
https://youtu.be/DY7dLvb99gspretty wholesome. These people really fucking like rockets
>>12937470>>12937475No wonder people who worked on SLS never thought about how things could be better when all the other "big" space projects of the world are carried with the same enthusiasm as a bored middle schooler who just wants to play vidya, and probably same level of intelligence too
>>12937151>>12937344Goddammit, why are these retarded boomers with unchangeable mindsets everywhere? I keep getting motherfuckers just like this as reviewers for my papers and I keep having to call them out on their retarded out of date ideas. Day of the retirement house when.
>>12936456What a piece of shit
>>12937548>Goddammit, why are these retarded boomers with unchangeable mindsets everywhere?The Boomers were an enormous generation and then all started using birth control. Classic civilization killer.
>>12936512>>12936521Fucking piece of trash, stop spamming it you dumb nigger
>>12937555The future is Amish, Mormon, and Muslim. Ain’t so bad
>>12937555We talking about birth rates?
>>12937575Cute space duck.
>>12937565Unironically get help anon
Post rare Burans
>>12937598>uncensored upskirt shotenjoy the ban
>>12937594it's a mess but fuck me does it look cool
>>12937579Damn. Even Hispanics are below replacement rate.
>>12937617Keep in mind these projections are from before 2020 so they don't take the lockdown into account.
>>12937614Recent>>12937617I never understood the reusable welder meme
>>12937617>>12937623As someone who makes a hobby out of census and population data, I look forward to the full results on the affect of covid.
>>12937545Phenomenal. It's like humans have a natural love of space. It was always there, just dormant. SpaceX simply rekindled the fire that oldspace had smothered.
>>12937594in retrospect it’s wild that they were able to drop that brick on the landing strip every time
>>12937639or rather congress and politicians had smothered. Places like ULA were trying but kept getting shut down.>>12936421I wonder if they deliberately tried to make it look a bit like R2-D2. For normie appeal.
>>12937617Its almost like its expensive as fuck to live here, expensive as fuck to give birth here, and nothing is being done to alleviate these issues. When the bulk of the population struggles to keep themselves alive, how the fuck do you think they're going to scrounge up the money to support another?
>>12937617>>12937660US-born Hispanics have been under replacement rate for decades. That's why they fought Trump on the wall so hard.
>>12937660>Its almost like its expensive as fuck to live here, expensive as fuck to give birth hereIt isn’t tho as long as you avoid the mega cities
>>12937296If Australia goes from nothing to launching payload I will seethe to eternity. It just isn't fair... Brazil has been trying for a literal half century...
>>12937713>Brazilso what's their space program like? Have they ever seriously tried to build a rocket?
>>12937713/pol/ is always right
>>12937468his whole argument is built on top of the assumption that Ariane will never again be a commercially viable launch provider>step 1: declare defeatnow you’re thinking like a euro
>>12937720Yes. It got killed when pic related killed 21 people on the launchpad 3 days before launch.Since then, they handed over the project to the Germans who have done nothing but wank over it and produce a smallsat version that never got off the pad. We have our own Aerojew Shekeldyne (Avibras), who makes sure to delay the project as much as possible to keep on government payroll.https://en.wikipedia.org/wiki/VLS-1_V03
>>12937703The only really cheap places to live are out the middle of bumfuck nowhere. I live in a town of 18k people right now, and even though costs of living are lower than where I lived last (Hampton Roads area, Virginia), there's also FUCK ALL out here in this town. There are few jobs (most are with one flavor of megacorp or another), and the house I'm renting is $700 a month, just for rent. Most of the small businesses out here are either full up or folded when the pandemic hit.Assuming a min-wage job making about a thousand a month after taxes (if that), in one of the cheapest places around here that was available thats ~70% of the paycheck gone, just for a roof. Then there's power, gas, vehicle fuel, internet, phone, and food that all have to be paid for. If you're careful about it, you MIGHT be able to break even. God fucking forbid something goes wrong with your vehicle, or you have a medical emergency, or any number of sudden expenses come up.
>>12937344>>12937151french. 'ate 'em
>>12935604imagine a Shuttle Buran joint mission
>>12937654For as much hate as they get for being "oldspace", ULA truly is the Master Splinter in the "Ninja Turtles growing up" meme. They were fighting the good fight long before Spacex and Rocket Lab even existed
>>12937794Is this a pasta or something
>>12937813it is now
>>12937813not that anon, but ULA was about as ambitious as you could get using oldspace disposable rocketshttps://www.nasaspaceflight.com/2018/03/ula-laying-foundations-econosphere-cislunar-space/
>>12937151The French have been wrong quite a bit in recent generations. Lets not forget that their generals didn't believe in mechanization or a modern air force right before WWII
>>12937834>giant lightning bolt striking Boca Chicaoh, Tory
>>12937847looks closer to Houston or Dallas if you ask me
>>12937834ULA is based(relatively compared to the rest of oldspace) if you could jettison the tumor that is Boeing straight into a neutron star, or Arkansas whichever is denser at the time.
I fucking hate you spaceplane faggots but I'll be nice and share the new SNC video. >https://vimeo.com/530507911/4d375e144b
>>12937918Spaceplanes are a dead end anon i'm sorry in the short term capsules like the dragon are cheaper and already available and in the long term we have starship and future propulsive vehicles.
>>12937113if the price isn't less then a million its never happening
>>12937943The difference between a spaceplane and tail-sitter propulsive landing from orbit is the last thirty seconds of flight. The TPS belly flop takes it transonic so you either add wheels and aerodynamic controls to slow down on a runway, or you flip vertical and suicide burn.
For as much hate as they get for being "oldspace", Blue Origin truly is the turtle in the "tortoise and the hare" meme. They were fighting the good fight long before Spacex and Rocket Lab even existed.
>>12937548Just curious anon, what are your papers on?
https://www.bizjournals.com/austin/news/2021/04/02/sources-spacex-facility-planned-near-tesla-plant.htmlNew SpaceX facility planned in Austin. Might be new headquarters.
>>12937979And? suicide burns are the future.
somebody make a new thread
>>12937980Yeah the problem with that is the tortoise actually did something. Blue Origin does not. But here is a picture of a rocket that has already accomplished things and is actually real.
>>12937977well, elon's never been wrong before
>>12938045i don't think you understand 99% of the funding for the program anyways will come from starlink, not tickets
>>12935021Why don’t we just move mars into orbit around the earth?
>>12938011Not spaceflight per se but uranium chemistry
