Hohmann trajectories would be used to move from Earth- to Mars-orbit, and von Braun computed each rocket burn necessary to perform the required manoeuvres.

Von Braun calculated the size and weight of each ship, and how much fuel each of them would require for the round trip (5,320,000 metric tons). The fleet would use a nitric acid/hydrazine propellant that, although corrosive and toxic, could be stored without refrigeration during the three-year round-trip to Mars. The spacecraft, seven passenger ships, and three cargo ships, would all be assembled in Earth orbit using materials supplied by reusable space shuttles. 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 Mars Project is a technical specification for a manned mission to Mars that von Braun wrote in 1948, with a provisional launch date of 1965. The book has been described as “the most influential book on planning human missions to Mars”. It was written by von Braun in 1948 and was the first “technically comprehensive design” for such an expedition. 2 Synopsis The Mars Project is a technical specification for a manned expedition to Mars.
