Aussie_Space_Nut: "Mighty Space Truss" (2015)

Design summary

Launches. Five: 2 Dragons, 2 BA330s, and 1 foldable aluminium "Mighty Space Truss" (~10 t, >200 m, tubes of 100 × 6 and 50 × 3 mm) for a 100 m radius Aussie_Space_Nut, 2015-10-21.
Operating sequence. Dock only at 0 rpm; escape in the Dragons at any rpm; offset the counterweight to test two g-levels Aussie_Space_Nut, 2015-10-22.
Later Aussie variants (2019):
3 arms (5 launches) or 6 arms (9 launches), spun only when complete, in ELEO.
Battery packs on rails along the arms move the centre of rotation, allowing several docking ports near the centre Aussie_Space_Nut, 2019-03-31.
Dumbbell with a movable mass for lunar and Mars g at different ends Aussie_Space_Nut, 2019-03-26.
A lifeboat per hab, with occupants limited to lifeboat capacity Aussie_Space_Nut, 2019-04-01.

Docking at the rim needs high Δv; dock at the centre A_M_Swallow, 2015-10-21.
The spin-up/down fuel for 50 t at each docking is large, so add a flywheel and a central docking adapter mikelepage, 2015-10-22.
