How about a solar sail for braking? (We've got to be creative, I can't imagine there's no solution for slowing down.)

- polyfractal 14y agoI imagine you would need a ridiculously large solar sail to slow down the mass of an Orion. It's not that slowing down is impossible...you just start throwing bombs the other direction. But by slowing down you increase your travel time, so the 150 year estimate is no longer valid.
