Walter Hohmann

Walter Hohmann was a German engineer and scientist known for developing the concept of the "Hohmann transfer orbit," a method to move spacecraft efficiently between planets using minimal energy. This trajectory involves two engine burns: one to shift the spacecraft onto an elliptical path, and another to enter the target orbit. By optimizing fuel use, Hohmann's approach has become a fundamental principle in space travel, enabling cost-effective interplanetary missions. His work significantly contributed to modern astronautics, helping spacecraft reach planets more efficiently than previous methods.
