The problem with space travel is that the vehicles are a one time affair. Even the space shuttle, the so-called reusable launch vehicle, had to use huge disposable rockets to take it to space. So the hopes of a space vehicle which could be used again and again like a car or an air plane are dead? Not for the time being, at least. Elon Musk, the co founder of SpaceX, is on an attempt to develop a completely reusable space vehicle.
