This first video, about 1/2 hour long, has a recurring graph in it where they, item by item, put on it things that limit human comfort and habitation inside a rotating structure. In the end, you are left with a stripe of radius vs rotation rate where people would be OK. In other words, it answers things like what size your space station must be to “work”. I wish the low end of the graph was a bit more precise, but interpolating it looks like about 25 M is near the lower bound. So somewhere between 75 and 100 feet.
This is well inside the size of structures we’ve already built that rotate in a 1 G field, so ought not to be very hard to design something similar for space:
The London Eye is a cantilevered observation wheel on the South Bank of the River Thames in London. It is Europe’s tallest cantilevered observation wheel, is the most popular paid tourist attraction in the United Kingdom with over 3.75 million visitors annually, and has made many appearances in popular culture.
The structure is 135 metres (443 ft) tall and the wheel has a diameter of 120 metres (394 ft). When it opened to the public in 2000 it was the world’s tallest Ferris wheel. Its height was surpassed by the 525-foot (160 m) Star of Nanchang in 2006, the 165 metres (541 ft) Singapore Flyer in 2008, and the 550-foot tall (167.6 m) High Roller (Las Vegas) in 2014. Supported by an A-frame on one side only, unlike the taller Nanchang and Singapore wheels, the Eye is described by its operators as “the world’s tallest cantilevered observation wheel”.
Then this video is from the Gateway Foundation. It’s a bit “sellers puff” at times, but it looks like these folks have a well thought out design that could be put together in space and made operational fairly quickly. I think they are ‘over selling’ the notion that there will be a need for regular folks on the station (waitresses, cops, and janitorial), but then again if they are successful in selling it as a Hotel / Hot Spot then yeah, rich people will pay up for the service and won’t be happy with just a mini-bar in the room and high grade microwaved dinners… 24 minutes:
I would hope they will succeed. Though I doubt they will need old guys fixing computers ;-)
Not to be confused with the medical “Gateway Foundation”, the Spaceport one is here:
It looks like they have thought things out in stages and included issues like finances…
This is a segmented spaceport that will be revenue generating at each major stage of completion. This will be mankinds first space station with artificial gravity.
You could call it a destination hotel, a low Earth orbit cruise ship, or a city in space with a spaceport. But the best way to understand this complex piece of infrastructure is to look to its namesake: The Gateway.
That they are selling “memberships” is a bit of a trigger for me, but the BASIC is free (but no space perks) while for $40 per year or $400 one time you can get a “Crew Membership” and enter a lotto for a trip to space, if it ever happens…
I think their design is generally OK, and having escape ships next to each cabin space is a nice touch, but just the cost of hauling 22 mini-shuttles into space is “not small”; and one picture looked like there may be two at each point, so 44 total… And will there be 44 expert space pilots on station all the time? I suppose a robotic landing would be possible, but… with emergency decent from anywhere on orbit that’s a bit of an issue too. Or maybe they have enough supplies they can just auto-dock with the ISS and wait for a big space transport to come up and fetch them ;-)
OTOH, if you have a program where visitors get to sit in the pilot seat of the flyer and look out the window while thinking about flying it it, maybe it would have ‘pay off’. I note in passing the “drivers window” is looking “straight down” given their mounted position so you would need to stand on the display panels / windshield on entry… Maybe they need a different mounting orientation ;-)
