SpaceX Starship and The Von Braun Rotating Space Station

the Gateway foundation was formed to build the first spaceport in order to do that we must first build a few smaller structures first one of the most important is a von Braun rotating space station this will likely be the first commercial space construction project in history my name is John bling co and I'm president of the Gateway foundation [Music] [Music] in a station design that is not a corporate rotation is almost a waste of time for short periods of time but zero-g platform can make sense but if you have workers there for more than two or three months then forget it why you'll understand after I read to you a first-hand account by astronaut scott kelly after we returned for 340 days at the International Space Station every part of my body hurts all of my joints and all my muscles are protesting the crushing pressure of gravity I'm also nauseate 'add although I haven't thrown up a crack of light wakes me is it morning no it's just amiko coming to bed I've only slept a couple of hours but I feel delirious it's a struggle to come to consciousness enough to even move to tell her how awful I feel I'm seriously nauseated now feverish my pain has gotten worse this isn't how I felt after my last mission this is much much worse I struggled to get up find the edge of the bed feet down sit up stand up at every stage I feel like I'm fighting through quick sound when I'm finally vertical the pain in my legs is awful and on top of that pain I feel a sensation that's even more alarming it feels as though all the blood of my body is rushing to my legs like the sensation of blood rush into your head when you do a handstand but in Reverse I can feel the tissue in my leg swelling I shuffle my way to the bathroom I make it to the bathroom flip on the light look down at my legs they are swollen and alien stumps not legs at all I say amiko come look at this she kneels down and squeezes one ankle it squishes like a water balloon she looks up on me with worried eyes I can't even feel your ankle bones she says my skin is burning too I tell her and Miko frantically examines me I have a strange rash all over my back the backs of my legs the back of my head and neck everywhere I was in contact with the bed I wonder whether my friend Misha back in Moscow suffering from the same swollen legs and painful rashes I suspect so our space agencies won't be able to push out further into space to a destination like Mars until we can learn more about how to strengthen the weakest links in the chain that makes spaceflight possible the human body and mind this is a nightmare it sounds like a science fiction horror movie this is what 340 days in zero-g space did a Scott Kelly's body but was he okay after shorter trips to space here again in his own words on my previous flight to the space station a mission of 159 days I lost bone mass my muscles atrophied and my blood redistribute itself in my body which strained and shrank the walls of my heart more troubling I experienced problems with my vision as many other astronauts had people need gravity so that bodies won't fall apart but how much will lunar gravity be okay for a year but not for two years well Martian gravity worked for humans long term but not for large farm animals with two days a week at 30% G be enough for ISS crews to retain bone mass building the von braun's space station can help us unlock those secrets so let's have a look at the station Brown station will be a rotating Space Station designed to produce varying levels of artificial gravity by increasing or decrease in the rate of rotation the station will be designed from the start to accommodate both National Space Agency's conducting low gravity research and space tourists who want to experience life and a large Space Station with the comfort of low gravity and the feel of a nice hotel structure will consist of two concentric structural rings fixed together with a set of spokes supporting an outer habitation ring made up of large modules can have is an unpressurized ring structure with docking arms and stabilizers designed to capture and lock in place visiting spacecraft unload passengers and cargo at first there will be only one docking port but later we will add another so the two craft can be docked at the station at the same time all passenger and cargo access to the station will be through a set of pressurized access tubes connecting the docking hub to the outer ring truss the outer ring truss is a triangular unpressurized ring trust supported by network of spokes to the docking hub set inside this truss is an access tube that will allow people to move about the station freely below the outer ring trust are a series of large connected pressurized modules this is called the habitation ring our original design was very much like Wernher von Braun's rotating space station hence the name but we soon solved problems and had to change the design first where are the escape vehicles if you cannot evacuate the whole population during emergency then you have recreated the Titanic second if your modules here next to the elevator tube then everyone going to modules here and here must pass through yours coming and going every day so we created the access tube structure and designed big couplings to mount the escape vehicles on our original design had a square Oh Artie but dr. Thomas Locker changed the truss design from Square to try and get her to increase strength and reduce mass after that we decided to put the access tube inside it then we move the spokes when the center apex lawns run to the base launch rails this will allow the elevator tubes to rise up between the spokes at the juncture of each set of modules there will be a coupling that connects the modules together and connects the habitation ring to the outer ring access tube above it inside the outer ring truss set into the coupling floor will be an access door to the escape vehicles do you evacuate the facility should that need arise this matrix of pressurized tubes will consist of the docking hub access tubes the four elevator tubes and the access tube embedded in the outer ring trust above the ring of habitation modules the Gateway foundations construction arm orbital assembly will design and build a frame this will consist of the docking hub the spokes and the outer ring truss orbital assembly will also assemble the access tube network the couplings and the modules into the habitation ring those items will be built down here by other aerospace companies and launched ready to be assembled modules can be made by firms who have built modules for the International Space Station fails JAXA Boeing Rose cosmos or Bigelow Aerospace they could also be made by non ISS module makers Orion span axiom the Galactic sweet design orbital technologies and SpaceX there will be two different types of couplings the standard coupler will have three ports one of these joining module and one to the access tube network above there will also be an airlock at the bottom to allow access to the ERV below it the other type of coupling will be the same except below the airlock it will allow access to the reaction control tower with a control spin procession and position of the station as needed all access tubes and couplings will be built by one contractor for commonality there will be two hemispheres of 12 modules each hemisphere will have one krb kitchen restaurant bar one G a gymnasium auditorium and one AWP air water power processing module there will be at least one module for station crew the rest of the modules will be for customer use laboratories for national space agencies hotel rooms for paying guests and villas for those who can afford one this structure could actually be built rather fast why because the Leadenhall building was built fast this is the Leadenhall building the Leadenhall building was built in downtown London and it's considered by many architects as the most advanced building in the world it is the manner in which it was built that makes it so advanced from start to finish it took only 2 years to construct second it was built on a computer using a work schedule that a counter for every bolt tightened every window set in place minute by minute every day seven days a week for two years that is precision scheduling Leadenhall had a small footprint leaving no room for material storage on-site the same problem we have in space this meant every beam every window had to be set in place just when it arrived building von Braun's station will acquire the same kind of precision timing can permanent modular construction be used in space yes the Gateway Foundation has designed and patented a construction machine called the G cell which can build large trusses and frames quickly the docking hub and the outer ring trust are the only parts that need to be welded together in space the rest you just bolt together like they did with the modules at the International Space Station and the frame at leadenhall previously we were looking at mods there were 28 feet wide by 40 feet long these would be very impressive since ISS modules about half that size but if we had a SpaceX super-heavy 2nd stage it was developed just for space construction we can have modules there were 40 feet wide by 60 feet long this much bigger size will allow for a much larger interior volume for the same launch costs each of these modules would be configured to suit the demands of our customers there will be modules for station workers modules designed as laboratories and the modules be configured as hotels for space tourists and then there's my favorite the villa similar to how boeing will customize an airliner frame to create a VIP private jet so to well we have modules fitted for wealthy customers VIP jets can be very plush but this station will have far lower noise levels consistent pressurization and no turbulence or vibration he'll be more like a billionaires yacht well restaurant chains operate the restaurants while hotel chains operate the rooms and the tourist modules imagine what it will do for their loyalty programs if they have a drawing for a free ticket to those who join who could resist the von braun's stations design will laugh the meeting the collaboration of a community of nations with space programs corporations with space objectives and space tourists who want to visit space for a unique offworld experience shared use areas like the restaurants gymnasiums and game rooms will bring these people from different backgrounds together at the same time it will give each of these spaceflight entities the privacy we all need from time to time in their own modules rented spaces or hotel rooms national space agencies who will be able to buy and configure their modules as they see fit and then later sell their positions on the station to recover their expenditure the reselling of space property will completely change the dynamic of space expenditures from all with huge financial losses to one with great financial rewards von braun will be a rotating space station that is economically self-sustaining offering both community and privacy vital low-gravity research and tourism this is the station we need to build right now the Von Braun station first project for orbital assembly to test and use the tools we need to build space ports bots will help astronauts perform repetitious or dangerous tasks pods and arms will move heavy structural items into place drones will perform several jobs all over the construction site and the G cell or trust later or both will assemble large trusses for the structural rings by far the biggest reason to build a von braun's space station is to validate the basic design structure for the gateway spaceport the hub spoke and rim system of building space ports has never been demonstrated offworld and needs to be tested before we build big structures big enough to accommodate cities in space the first part to be built will be the frame does this structure look familiar it should we've done this before down here On June 9th 1893 the Chicago wheel achieved first rotation on this 264 foot wheel there were 36 passenger cars each able to accommodate up to 60 people given a total capacity of 2,000 160 the most famous is the London Eye in the year in 1999 the large hub spoke and rim structure in rotation was put to use in England this magnificent structure is not designed for long-term habitation but it's modern design of hub modules and try and get a ring trust validate the von braun stations major design elements under one gravity stress more such eyes have been built for singapore las vegas 9 Ching and Dubai just as there are more eyes around the world there will be more von Braun stations circling earth there will be eyes in the sky [Music] you the von braun's station is almost a reduced scale version of the Gateway spaceport there are literally a hundred ways that building this rotating Space Station will teach us how to build big space ports from power generation and air processing to structural load dynamics on a rotating frame for instance how do we keep the station in balance when a shuttle is offloading cargo in the hub how do we dampen oscillations how do we handle freshwater grey water wastewater how do we recycle air to keep it fresh not just okay but fresh enough for tourists some of those answers will be found in the design of a WP module this modules job will be to clean all the air and water and distribute power from the solar panels as needed to the modules how big does sickbay need to be for a population the size how many refrigerators and freezers for the kitchen the cruise ship industry can answer some of these questions building and operating farm burn station will be an important stepping stone to building bigger structures like space ports how to pay for this station tourists and tenants von braun's station will be just like an apartment building in New York City that has hotels restaurants gymnasiums auditoriums and temporary parking our buildings job will be to provide air water and power to our tenants and gravity but that's free of charge our list of possible tenants and clues number one sovereign customers NASA from America ESA from Europe JAXA from Japan Russia China India Australia Canada South Korea Brazil and more there are 13 nations who have launched rockets into orbital space there are over 70 nations with space programs number two space corporations SpaceX Virgin Galactic Blue Origin Bigelow Aerospace Boeing Lockheed and many more three space societies like as Gardea number for billionaires there are over 2,000 billionaires around the world how many would want to have their own villa offworld the option dome property in orbit has never come up until now with Jeff Bezos Sir Richard Branson bio module with Michael Jordan want to set up a basketball court at lunar gravity Hickey wears Jordans and jump around like that flubber inside there are lots of possibilities who foresaw that the first SpaceX starship client was an artist who wanted to have an experience like no one else has had for over five decades I believe that it'll happen the same way for the Von Braun station maybe even the same person who could resist the chance to have their own villa in space the first privately owned property offworld in history he or she might step out from a profession that is far removed from the space industry number five there is also the person who must have visit space for a few days but does not have enough money to buy their own villa for every billionaire was to visit space there are millions of well-off people who will buy a ticket to the orbital Hilton for a three-day offworld excursion and last number six my favorite is the middle-class person who wants to go to but can't afford to blow the retirement getting there for that person we have created the Gateway foundation crew membership each year we will choose one of these people from the first thousand members and one from the first 10,000 to visit the station at our expense we created the crew membership for lots of good reasons but the biggest one has to do with the powerful force of innovation stemming from human curiosity when everyday people get involved things start to move fast the biggest change this station will bring to space will be a much larger requirement of workers from many sectors of Industry many more scientists will be doing more research more astronauts to build operate and maintain the station more pilots to operate space shuttles space taxis and spacecraft and for the first time we will need workers from many walks of life just to run the station we will have restaurants so we will need waitstaff we will need cooks and we will need people to clean up after they say if you have a bar with footy on the telly then you have to have a brig so we will need security to the rooms will need to be clean and the sheets washed the gymnasium will need instructors to help people from twisting their ankles while they learn that weight is different from mass we will have a doctor or two we will need lots of people and those of you who are part of our gateway crew know that the first place that we look for motivated qualified people who want to be station crew is from our crew membership the Gateway foundation crew membership was created so people who share a passion for space travel could have a significantly higher chance of visiting space in their lifetime but it also gave us a pool of people to draw from who had talents and skills needed for designing and building space stations space ports and other large structures in space this has worked out really well we have been hiring from her crew membership exclusively for over a year now soon after first spin up there will be a need for other types of space stations nearby to help Van Brunt station function maintenance facilities will be need to repair shovels that loose tiles and reentry shielding or need viola components replaced there will be fueling depots and stations for service craft - well national space agencies want to have zero-g laboratories and co / la positions so they're scientists living there can get some exercise and good food every few days at least our weekends I would think so we first started making our cost projections for space construction we've based it upon the lowest estimated launch cost that we could find the space xbf are at a thousand dollars a kilogram that came out to around 150 million dollars a launch but then Elon Musk made a presentation and a delight that changed everything by making all the components of bfr reusable its cost could be spread over many flights just like an airliner Elon Musk estimates launch cost to the starship and super heavy booster at around seven million dollars some estimate that each launch will be as high as 40 million dollars after all the factors are accounted for but whether it's seven or forty million dollars that is still music to our ears this means it rotating space stations maintenance facilities and fuel depots can and will be built affordably NASA wants to go back to the moon but it really needs to learn about the long-term effects of low gravity - now they can afford to do both we will build von Braun's station and it could be built fast because many can afford to have a module at these prices my father's generations sent people to the moon when we build von braun's station we will make history - first rotation will be a monumental event much like the first steps on the moon but when the station first spins up there may be close to 400 people on board heads of state billionaires in the space industry and many celebrities the names of the first people to experience artificial gravity in space for the first time in history will be remembered as that who was there a moment for generations you don't want to miss this party if you are a gateway foundation crew member that at least two of you will be there that's in addition to any crew members who were hired as station crew well NASA and International Space Agency's by modules on bond brunt station yes because they will want to remain the leading nations in space exploration and low gravity research will tell us how we need to design spacecraft to explore our solar system for centuries to come the future of human space exploration is in rotation space has been one of America's most important areas of investment and technological dominance for decades but the importance of the station goes far beyond monetary investment an ROI it is the symbol of things to come it is affordable and revolutionary I believe America is a superpower that needs a super project this country has never done better than one has accepted the challenge of a great undertaking that would change everything the spacex starship the von braun rotating space station will usher in an era of space habitation and space communities long dreamed of but never attained we have the technology to build the station and it is economically feasible this is going to happen because as time has come and it could happen fast because a lot of the things that we need are already made or can be fabricated with off-the-shelf materials and technology once again I would like to thank the Gateway foundation crew members who supported this effort and those who have joined us recently you were helping us a lot and we listened to your ideas now I want to tell you a little bit about our crew we are not from a few nations we're from all over the world in fact it's only a matter of time before we have Gateway foundation crew members representing every nation on earth we are a team with a common objective to form a space construction industry to create transportation infrastructure offworld and to transition humankind into a spacefaring race if you'd like to join our crew go to Gateway space port comm slash membership our next episode will focus on the design challenges dr. Thomas bilker and I have addressed on the von braun's station for the last eight months thank you for watching and be sure and subscribe to our Channel [Music] you

As just a quick observational 2¢ on their design, it would make far more sense to have re-entry capsules for escape pods than shuttle/dream chaser designs. If the only purpose is for unscheduled escape from the station, a tried a true more simplistic design is not only safer, but also more cost effective.

[u/MartianEgyptianAlien]

I don't gamble I'm against gambling in general and don't like how they want to finance the space station but i like there concept and being open-minded to use starship and building the space station around it.

[u/frowawayduh]

My vision is similar. Escape pods would be conical, seat 20+. Central hub would not be hollow, but a long core truss with docks at ends and with big gyro units to control precession with electricity, not fuel. I favor a sun-synchronous polar orbit with one precession per year so one side is always illuminated by the sun and the other always faces the deep cold of space. This minimizes cyclic hot-cold stresses and assures steady power supply and thermal radiation with lower redundancy of arrays, radiators, and battery storage. I’d have an intermediate ring so the outermost habitation g-level would be Earth-like and the intermediate ring would be at a lunar or Martian g-level. This allows engineering, agronomy, and human factors labs to do the pre-work needed before colonization.

I also think radiation and micrometeorite shielding will be a major factor. Modules would be double-walled with the gap empty at launch but filled with a viscous resin on orbit. Something like a borosiloxane that would crosslink into a gel to self-seal and would also offer high absorption of some types of radiation.

There is no way that this will be the first use of artificial gravity in space. A tether model is far simpler and requires zero in space construction.

Having the dreamchasers on there with the triangular trusses now looks like their ideas are trending towards MVP. They are clearly trying to capture and attach themselves now to the hype from Bigelow and SpaceX, but to be honest I think there may be something to be said for them all approaching investors together.

• The largest risks of an orbital construction effort is reliable, efficient, and affordable dumb mass to orbit and economies of scale for pressurized volume and life support.
• The largest risk to providing economies of scale for pressurized volume and life support is reliable, efficient, and affordable dumb mass to orbit, and the orbital construction and assembly to remove redundancies to increase mass to volume efficiencies.
• The largest risk to providing reliable, efficient, and affordable dumb mass to orbit is an economic driver to launch stuff to orbit, and the lack of economies of scale applying to the mass being sent to orbit.

The union of these three create a feedback loop which continuously lowers the cost and risk of their counterparts until they do really become inevitable.

SpaceX has been looking at NASA because so much of it's existence is owed to their contracts, but investors have a lot more free capital with less operational dissonance, and far fewer politically motivated strings attached. This triumvirate would give them a compelling market to sell to investors.

What the hell is going on with the artificial gravity in the second-generation design, the "gateway spaceport"?

Look at 0:50-1:05. In the room under where the ship is landing, there are people walking around in an apparently comfortable level of gravity just 10% of the way from the center to the outer ring, meaning the outer ring must have a completely unlivable level of gravity. And that room that they're walking around in has a flat floor, making the gravity at either end noticeably stronger than in the middle, and not perpendicular to the floor.

By the way, did this guy's voice and intonations remind anyone else of a Rex Kwon Do presentation?

[u/ravenerOSR]

This seems very low density, and will need a lot of launches, assembling the habitation "pills" from aluminum or steel rolled sheets, and prefab domes (they stack pretty well) you could cut down a lot on launches.

I couldn't help thinking, Mars One is dead - long live Mars One.

Another scam?
