I was thinking two 60,000 pound engines, quite a bit bigger than Centaur. The idea is similar though, the engines can relit numerous times. Structure would also be more substantial but more rugged and reliable. I was thinking 100,000 pounds of payload. <br /><br />If you use the same Modules that make up the upper stage, as well as the first stage, to build Stations, transfer vehicles, cargo containers, lunar and Mars Stations and whatever else. A standard Module would allow 60x15 feet of unobstructed space, a fuel tank or cargo container. By adding upgrades, power and life-support the same Module could become whatever is needed. <br /><br />It should be easier to store LH2 in orbit because of the lower temperatures, a lot less cryogenic coolers needed. Transfering gasses and fluids in Space has been well proven. In my plans each Module will come with conduits and plug-in connecters Hydrogen, Oxygen, Nitrogen, electricity, data, water, ect., built in. <br /><br />I think it should all be re-usable. The first stage returns for a powered landing at the launch site and the second stage stays in Space for re-use.<br /><br />Anyone know the status of the Shuttle facilities in California, if nothing else the plans still exist. <div class="Discussion_UserSignature"> </div>
