Well, for the journey to Mars, 2 starships, tethered at the nose together, you would need a 150m tether length to give the ships a comfortable 1/3 gravity ( Mars) at a comfortable 2 RPM.
Space Colonization Options (Orbiting Stations, planets/moons)
- Thread starter valkyrie013
- Start date
Call it 150 tons each and you'd need a 7 ton cable less than 3 inches thick even with a lot of safety margin, easilly doable.
Question is is there a mounting point on starship which could take the entire weight.

Easily make a mounting point. could use the stud lift points.
Also done some maths for a 1 ship tumble gravity. if you do 4-5 rpm you get some decent gravity at the nose.
4-5 rpm constant is pretty uncomfortable. So maybe 3-4 hours a day to reset there systems, fluids, bone density would not drop. and 5 rpm for a short time a day is acceptable.

1 RPM is suggested as what would be comfortable for the masses/majority of folks.
Why limit to 150m cable. Make it 500m and reduce the rpm a lot fir little loss is payload mass.

Interlaced origami structure enables compact storage and high-strength robotic deployment
Researchers at the Department of Mechanical Engineering, Seoul National University, have applied the principle of interlacing to an origami-inspired structure and developed a "Foldable-and-Rollable corruGated Structure (FoRoGated-Structure)" that can be smoothly folded and rolled up for compact...
I think it would work best with some sort of center element, mass at the center of the two rotating dragons. reason being if you wanted to have anything dock, or you needed to have a course correction change, any change in a system where it's just two systems spinning around each other, will cause increase in instability until one is very noticeable rotating around with other albeit with significant wobble. in such a circumstance the dragons could be reeled in occasionally to the central hub, course corrections made, refueling, etc, then let back out. The crew don't need to be in grav at all times, just enough for health (whever just enough actually is, since no one knows)
Astronauts lose 1-2% Bone Mass every month and struggle for a very long time to regain it once back on Earth.
So it's probably a good idea to minimize Zero-G time if possible.
Zero G for a few hours or days in orbit at either end is fine. I don't see any need to dock in the centre of a spinning en-route -- what would they need to dock with?
As an experiment of how centrifugal gravity works in reality, a pair of Dragons in Earths Orbit for a week would seem to be a very cost effective way of doing science. OK they aren't big, but they are bigger than the Apollo command modules.
You could even have them uncrewed and leave them for a year with experiments going.

imagine if there was cites on the moon and colony style space stations in outer space
It's a future we could have had had the space program continued right through the 70s, 80s, and 90s and not been held back
For All Mankind showed one mostly realistic possibility of the future. Protests in the 80s from people in the fossil fuel industry out of a job due to lunar based helium fusion, race for mars in the 90s, asteroid redirections and Mars colonies in the 2000s etc.

exactly
the hell are you talking about? Whose space program? The only country that backed out of having a space program was the UK in the 70s.
The US one of course after the Moon they all but forgot humankind in space.. If that had continued we'd have a heck of a lot more of a human presence in space and on the Moon
The US has been putting people in space, with gapes between Apollo And STS-1, and two gaps after shuttle losses and the time between the retirement of the shuttle and the first crewed dragon flight. They currently have three different vehicle designs technically capable of human spaceflight and a fourth that could be readied.
The US didn't forget about space.

One pull of a string is all it takes to deploy these complex structures
MIT researchers have developed a new method for designing 3D structures that can be transformed from a flat configuration into their curved, fully formed shape with only a single pull of a string.
