Some sci-fi ideas with FF–what if we could get to Mars in two weeks? Jupiter’s moons in a month? How would that change manned/unmanned exploration?
A multistage Saturn-sized FF rocket could get a small payload to 1/3 the speed of light. Proxima Centauri in 15 years or so–shorter than many of NASA’s projects start to finish.
Reasonably sure at that speed you can use interstellar magnetic fields for breaking so that reduces fuel needs–only acceleration and maneuvering at destination, not deceleration.
