Ah, I have an idea for NASA - 1920’s style “Death Rays” mounted on satellites to blow up asteroids.
Or here is another one - it is obvious that chemical reactions simply don’t provide enough energy to lift large payloads into orbit cost effectively.
Therefore, I purpose that NASA construct a craft that uses nuclear reactions to launch spacecraft. And you don’t need a fancy engine either - just dropping a series of nuclear bombs out the back, behind a large steel plate, will give enough energy launch spacecraft the size of battleships into orbit. Just make sure to have extra heavy duty shock absorbers inbetween the steel plate and the crew compartment. And the spacecraft could be built out of steel, instead of fancy exotic materials, in normal shipyards, reducing the cost even more.
With this sort of craft, it would only take a couple months to send a crew of dozens or more, anywhere in the solar system. Think of the scientific knowledge it could bring.
I think space technology and space research should be put to use to eradicate hunger and bring peace to earth.
I hereby propose that NASA establish a colony on the moon, along with a mining facility for extraction and purification of all the green cheese that is found there.
