| Jumping off your last sentence - using resources more efficiently is exactly what a big part of space research is all about. In learning how to travel to space we will be doing research into more efficient propulsion, waste recycling, power generation, food production and a thousand other little areas that will turn around and benefit the earth as well. A lot of people seem to think that spending money on space research is the equivalent of throwing that money up into space for it never to return. This applies to a lot of other pure science research as well. | |
