, von Braun was recruited by the Germany Army to assist in the building of long-range military rockets. He quickly rose through the ranks and became technical leader of the team that developed the V-2 rocket. Towards the end of the war over a thousand V-2s were launched from Germany and bombed England. In 1944 von Braun was arrested by the Gestapo

 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 shuttle

 to the identified base camp site and build a landing strip. The rest of the ground crew would descend from orbit to the landing strip in wheeled gliders. A skeleton crew would remain behind in the orbiting ships. The gliders would also serve as ascent craft to return the crew to the mother ships at the end of the ground mission.

Von Braun based his Mars Project on the large Antarctic expeditions of the day. For example, Operation Highjump
Operation Highjump
Operation Highjump , officially titled The United States Navy Antarctic Developments Program, 1946-1947, was a United States Navy operation organized by RADM Richard E. Byrd Jr. USN, , Officer in Charge, Task Force 68, and led by RADM Richard H. Cruzen, USN, Commanding Officer, Task Force 68....

 (1946-1947) was a United States Navy program that included 4,700 men, 13 ships and 23 aircraft. At the time, Antarctic explorers were cut off from the rest of the world and the necessary skills had to be on hand to deal with any problem that arose. Von Braun expected the Martian explorers to face similar problems and included a large multi-disciplined crew in his mission, and multiple ships and landers for redundancy to reduce risk to personnel.

Shortcomings

In his introduction to The Mars Project, von Braun stated that his study was not complete. He said that he had omitted the details of some topics that would need to be addressed further, including the eccentric orbit
Orbital eccentricity

s, and the long-term effect of spaceflight on humans.

But there are other shortcomings in The Mars Project that von Braun could not have anticipated. He had not planned on any unmanned exploratory missions to Mars taking place before the first manned expedition. Von Braun had not foreseen the technological advances that would take place and the development of robot spacecraft. It was not until 1965 that the unmanned Mariner 4

 spacecraft found that the density of the Martian atmosphere was one tenth of what had been estimated. Von Braun's huge winged gliders would not have been able to land horizontally on the surface of Mars. The danger of high energy solar radiation beyond low Earth orbit was not known in 1948. The Van Allen radiation belt

s that protect Earth from solar radiation were discovered only in 1958, and von Braun did not plan for the protection of the crew in space and on the Martian surface from such radiation.

Influence

The Mars Project was the first technical study on the feasibility of a manned mission to Mars, and has been regarded as "the most influential book" on planning such missions. Mark Wade wrote in Encyclopedia Astronautica
