✦ Synopsis

The Mars Project is a technical specification for a manned mission to Mars that von Braun wrote in 1948. The expected launch date was 1965. He envisioned an "enormous scientific expedition" involving a fleet of ten spacecraft with 70 crew members that would spend 443 days on the surface of Mars before returning to Earth. The spacecraft, seven passenger ships and three cargo ships, would be assembled in Earth orbit using materials supplied by reusable space shuttles. The fleet would use a nitric acid/hydrazinepropellant that, although corrosive and toxic, could be stored without refrigeration during the three-year round-trip to Mars. He calculated the size and weight of each ship, and how much fuel they would require for the round trip (5,320,000 metric tons). Hohmann trajectories would be used to move from Earth- to Mars-orbit, and von Braun computed each rocket burn necessary to effect the required manoeuvres.Once in Mars orbit, the crew would use telescopes to find a suitable...
