Michael Andrew Minovitch (born c. 1936) is an American mathematician who produced spacecraft trajectories enabling a craft to gain velocity by travelling close to a planet orbiting the sun. His own personal gravity assist technique was developed in the early 1960s when he was a UCLA graduate student and working summers at the Jet Propulsion Laboratory. In 1961 Minovitch began using the fastest available computer at the time, the IBM 7090, to solve the three-body problem. He ran simulations and developed his own solution by 1962.〔
Early studies of comets in the late 19th century showed that their orbits were quite different after they had made a close approach to Jupiter. This indicated that a transfer of energy had occurred during the encounter.
The first mission to use a gravity assist was Pioneer 10, which increased its velocity from 52,000 km/h to 132,000 km/h as it passed by Jupiter in December, 1973.
Minovitch patented a vehicle for space travel under the patent title ''Magnetic propulsion system and operating method'', US Patent 6193194 B1.
