Work has continued on my Moonlab project from page 156.
Following the same mission profile I delivered the Cassiopee module to a docking with the Esastar, and together the two of them form the bulk of the station. I also added two inflatable modules that are light enough to be delivered via S-IVb without a refueling flight. Because of persistent difficulties having enough fuel for the Antares-LR to make the TEI burn after using fuel for rendezvous, I decided to leave one of the S-IVbs docked to an inflatable module to serve as an on-site propellent depot. The side docking ports I added to the S-IVb's config file are perfect for topping off the Antares-LR's tanks just enough to make the burn home. Periodically, a cargo-less stretched S-IVb is flown to provide additional propellent for the depot. Just 10-15% of the stretched S-IVb's capacity is enough to refuel 3 or 4 Antares-LRs enough for TEI.
The other big change came with Grover's LBS. Utilizing the Energia for launch, I finally had a cool way to deliver a lander. After all, what use is a station in lunar orbit if you don't have a way to shuttle to the surface and back? Also, CTVs and ATVs provide an alternative to the Antares for delivering crew and cargo to Moonlab. The whole project represents quite the international effort, with American Saturns, Russian Energias, ESA modules and landers, and Italian Antares. :lol:
I'm thinking about trucking an N-1 down to Wideawake and sending a Soyuz to pay a visit. Alternatively, I may launch an S-IVb into orbit, launch a Soyuz with the regular launcher, then dock it to the S-IVb for TLI. But, if I do that, I don't know if the S-IVb will have enough fuel for rendezvous plus TEI. The Soyuz has such a uselessly small delta-v budget that I have to rely on an attached booster to fly the entire mission, with the Soyuz providing little more than a reentry means.
Ideas?
