Later versions of the mission proposal, featured in the Disney "Man In Space" film series, showed nuclear-powered ion-propulsion vehicles for the interplanetary cruise.Īrtist's conception of the Mars Excursion Module (MEM) proposed in a NASA study in 1963. In the 1956 revised vision of the Mars Project plan, published in the book The Exploration of Mars by Wernher Von Braun and Willy Ley, the size of the mission was trimmed, requiring only 400 launches to put together two ships, still carrying a winged landing vehicle. (Winged landing was considered possible because at the time of his proposal, the Martian atmosphere was believed to be much denser than was later found to be the case.) The mission itself featured a fleet of ten spacecraft with a combined crew of 70 heading to Mars, bringing three winged surface excursion ships that would land horizontally on the surface of Mars. Von Braun's Mars project envisioned nearly a thousand three-stage vehicles launching from Earth to ferry parts for the Mars mission to be constructed at a space station in Earth orbit. Willy Ley popularized a similar mission in English in the book The Conquest of Space (1949), featuring illustrations by Chesley Bonestell. Details were published in his book Das Marsprojekt (1952, published in English as The Mars Project in 1962 ) and several subsequent works. Wernher von Braun was the first person to make a detailed technical study of a Mars mission. ![]() Wernher von Braun proposal (1947 through 1950s) David Portree's history volume Humans to Mars: Fifty Years of Mission Planning, 1950–2000 discusses many of these. Over the last century, a number of mission concepts for such an expedition have been proposed. Mission proposals 20th century įuel is mined from Phobos with the help of a nuclear reactor.

For comparison, the low Earth orbit payload capacity per launch of the U.S. LEO mass refers to how much hardware must be put in low Earth orbit for the mission. The list is in semi-chronological order, with some groupings, as variation can exist in the dating of a given plan. Von Braun's Mars "flotilla" included ten 4,000-ton ships with 70 crew members. It was originally published as Das Marsprojekt in West Germany in 1952, and as The Mars Project in English in the United States in 1953. The first engineering analysis of a crewed mission to Mars was made by Wernher von Braun in 1948. Later NASA probes in the 1970s, 80s, and 90s confirmed the findings about Mars environmental conditions. The new data meant redesigns for planned Martian landers, and showed life would have a more difficult time surviving there than previously anticipated. No magnetic field or Martian radiation belts were detected. Also of note, the Mariner 4 Mars flyby in 1965 provided radically more accurate data about the planet a surface atmospheric pressure of about 1% of Earth's and daytime temperatures of −100 degrees Celsius (−148 degrees Fahrenheit) were estimated. In addition, the lowest available transfer energy varies on a roughly 16-year cycle, with a minimum in the 19 launch windows, rising to a peak in the late 70s, and hitting another low in 19. Portree notes that every 26 Earth months a lower energy Earth to Mars transfer opportunity opens, so missions typically coincide with one of these windows. ![]() Many mission concepts for expeditions to Mars were proposed in the late 20th century. ![]() Mission profiles include crewed flybys, crewed landers, or other types of Mars system encounter strategies. ![]() It is limited to studies done with engineering and scientific knowledge about the capabilities of then current technology, typically for high-budget space agencies like NASA. This list of crewed Mars mission plans is a listing of concept studies for a crewed mission to Mars during the 20th and 21st centuries. This rocket is envisioned as the launch vehicle for some of the latest NASA speculative long-term plans for Mars concepts, although there are some bold private venture plans that may also provide mass-to-orbit for any mission until a space-faring colony could provide a launch from another body or space station.
