Round trip to Mars would push radiation safety limits Astronauts could easily soak up their lifetime allowance Mars waits for no man. The Mars astronauts need the awesome power of LENR to get to the Red Planet as fast as possible. How big does the reactor need to be to get to push the Mars rocket to its destination in just a few weeks? An ion engine could be coupled to a LENR based stirling engine electric generator. This power source would be both light and powerful. Such an engine would be lighter than the weight of the shielding required for a slow flight. It looks like LENR is coming along just at the right time to make space colonization possible.
