Born in Berlin, Ehricke believed in the feasibility of space travel from a very young age, influenced by his viewing of the Fritz Lang film Woman in the Moon. At the age of 12, he formed his own rocket society. He attended Berlin Technical University and studied celestial mechanics and nuclear physics under such luminaries as Hans Geiger and Werner Heisenberg, attaining his degree in Aeronautical Engineering.
He worked at Peenemünde as a propulsion engineer from 1942 to 1945 with Walter Thiel, then went to the United States with other German rocket scientists and technicians under "Operation Paperclip" in 1947. He worked for a short time with the Von Braun Rocket Team at Huntsville.
In 1948, while working for the U.S. Army, Ehricke wrote a story about a manned mission to Mars called "Expedition Ares". It anticipated the many challenges that still face explorers who will make the journey in the future. In the same year he wrote a book with Wernher von Braun, The Mars Project, which detailed how man could travel to Mars using a ferry system.
Upon leaving government service Ehricke worked at Bell Aircraft, and then for Convair in 1952. While at Convair, he designed the D-1 Centaur, the world's first upper-stage-booster that used liquid hydrogen and oxygen. He also created an early space station design, based on launch by Convair's Atlas rocket. The NEXUS reusable rocket was a 1960s concept design by a group at General Dynamics led by Krafft Ehricke.
Krafft Ehricke undertook a major, multi-decade study of the industrial development of the Moon, which he described as Earth's "seventh continent." His lunar industrialization concept was based on the most advanced technologies, such as nuclear-powered freight transporters, and using fusion energy to power his city, Selenopolis, on the Moon.
Ehricke received a space burial on April 21, 1997, when a rocket sent a small amount of his cremated remains into Earth orbit.
He married Ingeborg Ehricke (born 12 September 1922).
Ehricke promoted a philosophical concept called the "Extraterrestrial Imperative." This idea refers to Ehricke's belief that it was the responsibility of humanity to explore space and exploit the resources of the Solar System, in order to sustain the development of the species. There are no external "limits to growth," Ehricke insisted, because while the Earth is a "closed system," the exploration of space opens the universe to humanity. For Ehricke, human creativity has no limits.
