Anonymous Coward User ID: 73005875 United States 09/18/2016 04:03 PM Report Abusive Post Report Copyright Violation | Its actually pretty simple math. Now the math that allowed Voyager I and II to visit so many planets and use each one for a gravity thrust assist was COMPLEX. That was until a 25-year-old mathematics graduate called Michael Minovitch came along in 1961. Excited by UCLA's new IBM 7090 computer, the fastest on Earth at the time, Minovitch decided to take on the hardest problem in celestial mechanics: the "three body problem". The issue was being able to reach the outer planets in practical timeframe The three bodies it refers to are the Sun, a planet and a third object such as an asteroid or comet all travelling through space with their gravities acting on each other. The problem is predicting exactly how the gravity of the Sun and the planet will influence the third object's trajectory. Astronomers had been pondering the three-body problem for at least 300 years, ever since they'd started plotting the path that comets took as they fell through the inner Solar System towards the Sun. 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 NASA's Jet Propulsion Laboratory in Pasadena, CA. 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.

If they cant do it here, they cant do it on the moon. Has there been an actual video outside of the fake moon landing videos that shows the LEM actually touching down...any where? |
