An alternative storyline to the Mars transport architecture: Tankers refuel starship, last Tanker gets mounted on the Starship for the Mars orbital injection burn, once on a Martian trajectory tanker repositions/tethers engines facing each other and achieving, for the populated areas(35-50m radius) 0.35-0.5g's with 3 rot/min. Could use front fin boosters for rotation/emergency stops during solar events when the Tanker could be positioned as a supplementary radiation shield. So... Mars Transport Architecture How long is the mars orbital injection burn and could that time be adjusted so the forces involved don't add to much structural weight if the ships are attached during burn?

    $\begingroup$ If you think of centrifugal forces as artificial gravity, you should express that clearly in the question. $\endgroup$ – Uwe Apr 16 at 11:11

    $\begingroup$ everything would be upside down. Nose to nose, with or without a tether, would make more sense. $\endgroup$ – JCRM Apr 16 at 13:38
  • $\begingroup$ The cabins are near the nose, less rotations and a bigger radius with the nose positioned outwards, with 3rot/min might even manage to peak out the window $\endgroup$ – drandrul Apr 16 at 22:45

    $\begingroup$ Tethers for achieving a large rotation radius seem easier to deal with than building everything to work in microgravity and two 180 degree opposed gravity environments. And why send a tanker to Mars, taking it out of tanker duty for a couple years, instead of another ship carrying useful cargo? $\endgroup$ – Christopher James Huff Sep 8 at 0:34

Check out my design here:

It couldn't be done with a Tanker, but it's a similar idea in that a second vessel is used.
