[x] Gemini MOL (half pint service module, mounted on top of MOL)
[x] Min-mod Big G 1967 (conical one with addon crew module; total 9 crew; batteries only, S-IVB) CPM/Adapter not in BDB yet
[x] Advanced Big G 1969 (upgraded subsystems; 12-16 crew; Cargo Propulsion Module; fuel cells; Titan IIIM)
[x] Gemini Ferry (Titan IIID - probs no Transtage)
[x] Gemini Advanced Ferry
Titan IIIM CPM = 4.5m dia x 7.5m length; wider than the core stage!
Saturn INT-20 CPM = 6.6m x 12m (with 0.6m structural adapter) and forward cone adapter to crew module
Big Gemini (or "Big G") was proposed to NASA by McDonnell Douglas in 1969. Two baseline spacecraft were defined: a nine-man minimum modification version of the Gemini B called Min-Mod Big G and a 12-man concept called Advanced Big G.
Gemini Ferry uses the Gemini B short service module and then the ferry service module
Three potential launch vehicles - Saturn IB, Titan IIIM and Saturn INT-20.
