3. Who Discovered it? In the early 19-teens and the 20s Yuri Kondratyuk and Friedrich Zander both proposed similar arguments that said that a spacecraft traveling between two planets could be accelerated at the beginning of its trajectory and decelerated at the end of its trajectory. In the early 19-teens and the 20s Yuri Kondratyuk and Friedrich Zander both proposed similar arguments that said that a spacecraft traveling between two planets could be accelerated at the beginning of its trajectory and decelerated at the end of its trajectory. What neither of them realized was that you could use this force to propel a spacecraft forward with this gravity. This discovery was made by Michael Minovitch until the early 60s.

4. How and why it is used A gravational assist, or slingshot, is when a spacecraft uses the gravity of a planet or moon to pull itself around the mass at a faster speed. That speed is about 2U+v. A gravational assist, or slingshot, is when a spacecraft uses the gravity of a planet or moon to pull itself around the mass at a faster speed. That speed is about 2U+v. A gravitational assist can be used in the place of using fuel to power the engine because it is much more efficient. Therefore if a spacecraft is accelerating and time it takes getting to your destination is shortened.

This method was first used in 1974 to propel Mariner 10 around Venus to become the first spacecraft to explore Mercury.

5. Summary Gravitational slingshot is a benefit that should and will be used in our space travel in the future. It is very efficient and has proven that it can be a great aid in helping us travel through space and at the same time conserve fuel. The gravitational assist is a clever discovery and will always apply. Gravitational slingshot is a benefit that should and will be used in our space travel in the future.
