'From Ellipses to Gravity Assists' Webcast Presentation

Bottomquark writes "Tonight NASA scientist Charley Kohlhase, who has led trip-planning efforts for NASA missions to most of the planets in the solar system, will give a live webcast presentation called 'From Ellipses to Gravity Assists'. He'll explain how to choose the best routes for getting to destinations such as Mercury, Mars and Saturn, and describe how spacecraft can use the gravity of one planet to gain a "slingshot" boost toward a more distant destination. The 90 minute presentation takes place February 13, 2001 4:30-6:00 PM (PST) (24:30 GMT - 02:00 GMT), and will be broacast through LiveOntheNet.com (free registration required)."
