The Mars Project (German : Das Marsprojekt) is a 1952 non-fiction scientific book by the German (later German-American) rocket physicist, astronautics engineer and space architect Wernher von Braun. It was translated from the original German by Henry J. White and first published in English by the University of Illinois Press in 1953.
The Mars Project is a technical specification for a human expedition to Mars. It was written by von Braun in 1948 and was the first "technically comprehensive design" for such an expedition. [1] The book has been described as "the most influential book on planning human missions to Mars". [2]
Wernher von Braun developed a fascination for interplanetary flight while he was still at school in Germany. In 1930 he went to university in Berlin to study engineering, and there he joined the Spaceflight Society ( Verein für Raumschiffahrt ) and later worked on the design of liquid-fuel rockets. Shortly before the outbreak of World War II, von Braun was recruited by the German Army to assist in the building of long-range military rockets. He became technical leader of the team that developed the V-2 rocket. As the war drew to a close in early 1945 von Braun and his rocket team fled the advancing Red Army, and later surrendered to American troops. Von Braun and his scientists, plus 100 V-2s, were shipped to the U.S. Army's rocket research facility at Fort Bliss in New Mexico. [3]
In 1948 the U.S. Army's V-2 test program was completed and von Braun used his spare time to write a science fiction novel about a human mission to Mars. He based his story on comprehensive engineering diagrams and calculations, which he included in an appendix to the manuscript. The novel was not published, but the appendix formed the basis of a lecture von Braun gave at the First Symposium on Spaceflight held at the Hayden Planetarium in New York City in 1951. [1] The appendix was also published in a special edition of the German space flight journal Weltraumfahrt in 1952, and later that year in hardback by Umschau Verlag in West Germany as Das Marsprojekt. It was translated into English by Henry J. White and published in the United States in 1953 by the University of Illinois Press as The Mars Project. [1] [2] [4]

The Mars Project is a technical specification for a human mission to Mars that von Braun wrote in 1948, with a provisional launch date of 1965. [1] 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. [1] The spacecraft, seven passenger ships, and three cargo ships, would all be assembled in Earth orbit using materials supplied by 950 launches of three-stage reusable heavy-lift launch vehicles. 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. 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). 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. [4]
Once in Mars orbit, the crew would use telescopes to find a suitable site for their base camp near the equator. A crewed winged craft would detach itself from one of the orbiting ships and glide down to one of Mars' poles and use skis to land on the ice. The crew would then travel 6,500 km overland using crawlers 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. [1] [4]
Von Braun based his Mars Project on the large Antarctic expeditions of the day. For example, Operation Highjump (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, as well as multiple ships and landers for redundancy to reduce risk to personnel. [4]
In his introduction to The Mars Project, von Braun stated that his study was not yet complete. He said that he had omitted the details of some topics that would need to be addressed further, including the eccentric orbit of Mars, interplanetary astronavigation, meteor showers, and the long-term effects of spaceflight on humans. [2]
There are other shortcomings in The Mars Project that von Braun could not have anticipated in 1948. He had not planned on any uncrewed exploratory missions to Mars taking place before the first human expedition, and he had not foreseen the technological advances that would take place, or the development of robot spacecraft. [4] It was not until 1965 that the uncrewed Mariner 4 spacecraft found that the density of the Martian atmosphere was only one tenth of what had been estimated, making it clear that the huge winged gliders planned by von Braun would not have had enough lift to be able to descend safely onto the surface of Mars. [1] The danger of high energy solar and cosmic radiation beyond low Earth orbit was not known in 1948. The Van Allen radiation belts were not discovered until 1958, and von Braun did not plan for the protection of the crews from such radiation, whether in space or on the Martian surface. [1]
The Mars Project was the first technical study on the feasibility of a human mission to Mars, and has been regarded as "the most influential book" on planning such missions. [2] Mark Wade wrote in Encyclopedia Astronautica , "What is astonishing is that von Braun's scenario is still valid today." [1]
Between 1952 and 1954, one of America's popular magazines, [4] Collier's brought von Braun's ideas to the attention of the general public when they published a series of eight articles on space flight and exploration entitled "Man Will Conquer Space Soon!". Von Braun contributed to many of the articles, which were illustrated with paintings by space artists Chesley Bonestell and others. [1] The success of the Collier's series made von Braun a household name, and he appeared on several TV shows. He also collaborated with Walt Disney and appeared in three episodes of Disney's Disneyland TV program. [7] The two other shows that featured von Braun were "Man and the Moon" and "Mars and Beyond". [7]
In 1956 von Braun revised his Mars Plan and scaled down the size of the mission to two ships and 12 crew, requiring only 400 launches to launch the components and fuel to assemble in orbit. He published his results in a new book, The Exploration of Mars with co-author German-American science writer and space advocate, Willy Ley. [8] The original Mars Project was later republished by the University of Illinois Press in 1962, and again in 1991, with a foreword by American scientist and the third Administrator of NASA, Thomas O. Paine.
Von Braun's unpublished science fiction novel from 1948 was eventually published in Canada by Apogee Books in December 2006 as Project Mars: A Technical Tale . It included his technical papers on the proposed project and paintings by Chesley Bonestell. [3] [9] [lower-alpha 1]
Wernher Magnus Maximilian Freiherr von Braun was a German and American aerospace engineer and space architect. He was a member of the Nazi Party and Allgemeine SS, and the leading figure in the development of rocket technology in Nazi Germany and later a pioneer of rocket and space technology in the United States.
This article gives a concise timeline of rocket and missile technology.
Spaceflight is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflight operate either by telerobotic or autonomous control. The more complex human spaceflight has been pursued soon after the first orbital satellites and has reached the Moon and permanent human presence in space around Earth, particularly with the use of space stations. Human spaceflight programs include the Soyuz, Shenzhou, the past Apollo Moon landing and the Space Shuttle programs. Other current spaceflight are conducted to the International Space Station and to China's Tiangong Space Station.
The Space Race was a 20th-century competition between two Cold War rivals, the United States and the Soviet Union, to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following World War II and had its peak with the more particular Moon Race to land on the Moon between the US moonshot and Soviet moonshot programs. The technological advantage demonstrated by spaceflight achievement was seen as necessary for national security and became part of the symbolism and ideology of the time. The Space Race brought pioneering launches of artificial satellites, robotic space probes to the Moon, Venus, and Mars, and human spaceflight in low Earth orbit and ultimately to the Moon.
The Saturn family of American rockets was developed by a team of former German rocket engineers and scientists led by Wernher von Braun to launch heavy payloads to Earth orbit and beyond. The Saturn family used liquid hydrogen as fuel in the upper stages. Originally proposed as a military satellite launcher, they were adopted as the launch vehicles for the Apollo Moon program. Three versions were built and flown: the medium-lift Saturn I, the heavy-lift Saturn IB, and the super heavy-lift Saturn V.
Willy Otto Oskar Ley was a German and American science writer and proponent of cryptozoology. The crater Ley on the far side of the Moon is named in his honor.
Nova was a series of NASA rocket designs that were proposed both before and after the Saturn V rocket used in the Apollo program. Nova was NASA's first large launcher proposed in 1958, for missions similar to what Saturn V was subsequently used for. The Nova and Saturn V designs closely mirrored each other in basic concept, power, size, and function. Differences were minor but practical, and the Saturn was ultimately selected for the Apollo program, largely because it would reuse existing facilities to a greater extent and could make it to the pad somewhat earlier.
Conquest of Space is a 1955 American Technicolor science fiction film from Paramount Pictures, produced by George Pal, directed by Byron Haskin, that stars Walter Brooke, Eric Fleming, and Mickey Shaughnessy.
"Man Will Conquer Space Soon!" was the title of a series of 1950s magazine articles in Collier's detailing Wernher von Braun's plans for human spaceflight. Edited by Cornelius Ryan, the individual articles were authored by such space notables of the time as Willy Ley, Fred Lawrence Whipple, Dr. Joseph Kaplan, Dr. Heinz Haber, and von Braun. The articles were illustrated with paintings and drawings by Chesley Bonestell, Fred Freeman, and Rolf Klep, some of the finest magazine illustrators of the time.
Von Braun Ferry Rocket was a concept design for a shuttle spacecraft that was developed by Wernher von Braun in a seminal series of early-1950s Collier's magazine articles, "Man Will Conquer Space Soon!" by Wernher von Braun et al. The Ferry Rocket concept has evolved over time.
Krafft Arnold Ehricke was a German rocket-propulsion engineer and advocate for space colonization. Ehricke is a co-designer of the first Centaur liquid oxygen/liquid hydrogen upper stage.
John Cornelius Houbolt was an aerospace engineer credited with leading the team behind the lunar orbit rendezvous (LOR) mission mode, a concept that was used to successfully land humans on the Moon and return them to Earth. This flight path was chosen for the Apollo program in July 1962. The critical decision to use LOR was viewed as vital to ensuring that man reached the Moon by the end of the decade as proposed by President John F. Kennedy. In the process, LOR saved time and billions of dollars by efficiently using the rocket and spacecraft technologies.
Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky, Robert H. Goddard, and Hermann Oberth. First successful large-scale rocket programs were initiated in the 1920s Germany by Fritz von Opel and Max Valier, and eventually in Nazi Germany by Wernher von Braun. The Soviet Union took the lead in the post-war Space Race, launching the first satellite, the first man and the first woman into orbit. The United States caught up with, and then passed, their Soviet rivals during the mid-1960s, landing the first men on the Moon in 1969. In the same period, France, the United Kingdom, Japan and China were concurrently developing more limited launch capabilities.
The idea of sending humans to Mars has been the subject of aerospace engineering and scientific studies since the late 1940s as part of the broader exploration of Mars. Long-term proposals have included sending settlers and terraforming the planet. Proposals for human missions to Mars have come from agencies such as NASA, CNSA, the European Space Agency, Boeing, and SpaceX. As of 2023, only robotic landers and rovers have been on Mars. The farthest humans have been beyond Earth is the Moon, under the Apollo program.
A rotating wheel space station, also known as a von Braun wheel, is a concept for a hypothetical wheel-shaped space station. Originally proposed by Konstantin Tsiolkovsky in 1903, the idea was expanded by Herman Potočnik in 1929.
Saturn V is a retired American super heavy-lift launch vehicle developed by NASA under the Apollo program for human exploration of the Moon. The rocket was human-rated, had three stages, and was powered with liquid fuel. Flown from 1967 to 1973, it was used for nine crewed flights to the Moon, and to launch Skylab, the first American space station.
Space architecture is the theory and practice of designing and building inhabited environments in outer space. This mission statement for space architecture was developed at the World Space Congress in Houston in 2002 by members of the Technical Aerospace Architecture Subcommittee of the American Institute of Aeronautics and Astronautics (AIAA). The architectural approach to spacecraft design addresses the total built environment. It is mainly based on the field of engineering, but also involves diverse disciplines such as physiology, psychology, and sociology.
A single-person spacecraft is a vehicle designed for space travel. The concept has been used in science fiction and actual ships such as the Mercury capsule, Vostok and some suborbital designs. Single-person spacecraft have been envisioned as a supplement or replacement for space suits in certain applications. The Von Braun Bottle suit of the 1950s functions as a hybrid of a space suit and a one-person spacecraft.
Project Mars: A Technical Tale is a 2006 science fiction novel by German-American rocket physicist, Wernher von Braun (1912–1977), credited as Dr. Wernher von Braun. It was written by von Braun in German in 1949 and entitled Marsprojekt. Henry J. White (1892–1962) translated the book into English and it was published later by Apogee Books (Canada) in 2006 as Project Mars: A Technical Tale, almost thirty years after von Braun's death. The original German text remains unpublished.
