The Saga of NASA's Heavy Lift Launcher
Last week, after years of studies and negotiations, NASA finally released a preliminary design for the new rocket that will replace the space shuttle. The new rocket will be a Shuttle-Derived Heavy Lift Vehicle, meaning that it will make maximum use of existing Space Shuttle components. Basically they will keep the Space Shuttle External tank and two Solid Rocket Boosters unchanged, remove the space shuttle, take the shuttle's three main engines and put them and the bottom of the External Tank, and put the cargo on top of the External Tank. This design is pretty much the solution proposed by the DIRECT team last year, called the Jupiter launch vehicle.
