LCLV Various independently-funded launch vehicles have been advocated, designed, and even developed over the years. A lot of these are attempts to build low-cost launch vehicles using simpler technology. Often such projects begin based on a low cost liquid fuel technology but end up just trying to sell various combinations of Castor solid fuel stages. These enterprises often discover there's more to coming up with a reliable launch vehicle than slashing together a bunch of 'off the shelf' rocket motors and lighting the fuse.... On the other hand, if there is ever a breakthrough in less expensive access to space, it will come through one of these entrepreneurial schemes... More...
