This artist’s concept from 1962 show a three hundred-sixty ton spaceship, powered by a forty-megawatt nuclear-electric power plant, transporting a three-man crew to Mars. As envisioned by Marshall Space Flight Center engineers, a five-ship convoy would make the round trip journey in about five hundred days.
