That is the easy part. :>Now come up with something better, if you can that will get us to the moon on a :>regular basis. : :OK! I'll give this challenge a try. : :Instead of a earth-lunar "taxi", lets try a "tugboat/barge" concept. :Taxis carry only people, barges can carry materials and supplies. : :Let's put some of these tugboats into earth orbit. How? Unmanned using :an expendable. Let the crew tag along on a normal shuttle mission. :After the shuttle has completed its mission, it can rendezvous with the :tugboat and the crew can board it. : :The barges are lauched into orbit using expendables. The barge consists :of a number of payload canisters. Each canister is in the shape of :short cylinder. These canisters are stacked to create a long cylinder :shaped barge. The end canister is a special supply canister for the :tugboat. In this supply canister is food, air, water, etc. :Also fuel for the tugboat's rocket engines. : :OK, here's the scenario. Launch a barge into an earth orbit very close :to the tugboat's orbit. Launch a crew aboard the shuttle. Rendezvous :with the tugboat and board it. Tugboat then rendezvous with the barge :and docks with the supply canister. When docked, a access hatch :provides access into the supply canister, so that the crew can get :needed supplies. Also, fuel lines are connected between the tugboat and :the supply canister to replenish the tugboat's fuel tanks. Use the :tugboat's rocket engines to blast out of earth orbit and head for the :moon. On the way, turn around for lunar insertion. Blast into lunar :orbit. A lunar lander (already stationed at the moon and put there by :a previous mission) docks with the end payload canister. The payload :canister disconnects from the barge and the lunar lander takes it down :to the lunar surface. Unload the payload canister and blast up to orbit :to get the next canister. Each of the payload canisters can carry fuel :for the lunar lander so that each time it docks with a payload canister, it :gets refueled. Meanwhile, the tugboat and it's supply canister can :disconnect from the barge and blast out of moon orbit and head back to :earth. In earth orbit, the shuttle rendezvous to pickup the crew and :the supply canister (it can be taken back to earth to be reused). : :A space station would be usefull in this scenario. The tugboats can :dock with the space station. The crew can live at the station between :missions. Maintenance of the tugboat can be done at the station. etc. :A small station in lunar orbit might be useful for the same reasons. : :Ok, your turn. Is this a workable idea? What are the flaws? Is it :economical? I'll let the experts take this idea apart. Be nice :) : Sounds reasonable. Now redo it using Energia to put up the heavy stuff, Soyuz for shifting people around, Mir for the rendezvous in LEO and Proton for the supply. Hey, I just saved $5 billion. Gee, for that I can have tugboat big enough to go to Mars as well. Not to mention having enough $ left for an inflatable space station (courtesy of LLL) and enough $ to launch it (on Energia of course). No development costs either; better make that $10 billion. Of course, its all proven technology (safe). Better use trained personnel on this - one advantage is they can read the instruction manual - guess what language its in! Actually, what I REALLY want to know is how far from this the USSR thinks it is. Any opinions? Adam
