Wouldn't it be cheaper to strap thrusters onto the modules, launch em on big rockets and auto connect them to the ISS? <br /><br />I think lego ships are the way to go. Modular. <br /><br />Launch a dozen space ship modules, or CEVs and have them interconnect to form a larger ship, maybe once connected they could be encased with a hull or something else to add stability, you'd have a nice interplanetary spaceship. Just send up the crew module, connect, send up the fuel module, connect. And go to the moon and back! Easy!<br /><br />I always imagined a space navigation system based on starlight, the ship would know its precise location by triangulating via the light of 100s of stars and cross referencing, + its distance from the earth and moon. It could be on a display like a computer game, you'd see renders of the position of the ship in relation to nearby objects and installations. <br /><br />Another idea i have is to get rid of windows. Don't need em. Just strap 100s of micro cameras on the outside of the hull, and on the inside have a display that shows crystal clear live video showing you what is outside. It'd look like the front of the spacecraft was missing, but it wouldn't be. <br />
