Michael Andrew Minovitch (c. 1936 - 16 September 2022) was an American mathematician who developed gravity assist technique when he was a UCLA graduate student and working summers at NASA's 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. 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.
