Aiming for the Outer Planets

The video discusses Voyager's mission to the outer planets, highlighting the challenges faced in the 1970s due to limited rocket power. It explains the use of gravitational slingshot techniques to propel Voyager from Jupiter to Saturn, Uranus, and Neptune, taking advantage of a rare planetary alignment in 1977. Newton's law of gravitation is explored to understand how these maneuvers were possible, emphasizing the relationship between mass, distance, and gravitational force. The video concludes with the successful application of physics and mathematics in enabling Voyager's unprecedented journey into deep space.
