Ambitious missions of the next century, such as interstellar precursor missions out to 1,000 astronomical units (AU) in 50 years, and fast, 60-day round trip Mars missions, will require mission velocities on the order of 100 to 1,000 km/s, which are a factor of 10-100 greater than current mission requirements. A flyby mission to Alpha-Centauri in 50 years requires a velocity of 30,000 km/s (one-tenth the speed of light, c). Because the optimum exhaust velocity is typically on the order of...
