So I shamelessly stole your launcher to do something I've been thinking about for a while: Place a Skylab-like station in lunar orbit using almost-real technology.
The Big Dog launches from Wideawake, disintegrating the pad and everything else with it. Standard S-IC, 4 SRBs, stretched S-II and S-IVB carrying the ESASTAR module.
Makes it to orbit just fine, but the stretched S-IVB can't make the TLI burn unless it's 100% full of fuel. So...
Refueling flight launches from Jarvis. Standard, 2 SRBs, stretched, stretched. No payload because the S-IVB
is the refueling tanker.
Fuel transfer underway. Took 5 minutes to rig the S-IVBs with docking ports for this purpose.
TLI complete. Uses every freakin' drop of fuel in that stretched S-IVB, but it'll make it. The ESASTAR has a respectable amount of delta-v by itself and can handle LOI and some extra maneuvering.
Settling into lunar parking orbit.
First crew flight, Antares-LR from Kourou. Note the proper fairing and LES.
Fairing jet.
Still a little bit of gas left in the S-IVB's tank after TLI, I think I'll bring it with me. The Antares-LR's delta-v budget is pretty tight, and too much spent during rendezvous means no trip home for you.
Home, sweet home!
