From Ellipses to Gravity Assists
by Charley Kohlhase
This webcast begins with the simple notion of an ellipse, easily created by any young person, then moves on to Kepler's laws and the famous conic sections to slowly build a framework within which to understand how mission designers at JPL work out their special flight paths to the planets. In the early days of space exploration, Hohmann transfer ellipses were used to travel from the Earth to Mars and Venus. With the invention of gravity assist, journeys were soon made possible to the more distant planets, with the Voyager, Galileo, and Cassini missions being prime examples.
