Nagin Cox (The Galileo Mission to Jupiter-The Daring Return to Io: Moon of Volcanoes and Fire; The Mars Program: Step by Step Robotically to the Red Planet) works in NASA's JPL Spacecraft Systems Engineering Section. From 1995 until February 2000, she worked as the Deputy Team Chief of the engineering spacecraft flight team for the Galileo mission to Jupiter. Currently Nagin is the Mission Operations Engineer for the Mars Sample Return Mission.

On Friday, Nagin, will give a presentation titled "The Galileo Mission to Jupiter-The Daring Return to Io: Moon of Volcanoes and Fire". In 1492, explorers found a "New World" called America. Now, in our own time, another invincible ship is pushing at the frontiers of our knowledge. The Galileo spacecraft has been in orbit around Jupiter since December 1995 sending back stunning new images of this giant planet and it's incredible moons. In the Galileo Europa Mission of 1998-1999, the spacecraft Galileo completed the major portion of it's exploration of the mysterious moon Europa. Does Europa have an ocean? Galileo's data has been essential to answering that question. Now, Galileo has survived one of its greatest challenges- returning to the volcanic moon Io - deep in the heart of Jupiter's radiation belts. Come relive the journey through the solar system, experience the excitement of arrival at Jupiter and share in the wonder of Galileo's Millennium Mission - the ongoing voyage of discovery.

Since the beginning of time, people have been entranced by the night sky and by our nearest planetary neighbour- Mars. There have been many theories and fantasies over the years about what Mars may be like. Step by step, we are beginning to find out. From the early missions to Viking, Pathfinder, and the more recent missions - Mars has been (and is) a challenging destination. On Saturday in "The Mars Program: Step by Step Robotically to the Red Planet" join Nagin as we walk together through the past, the present and what the future may hold for us as we begin the process of making Mars a regular robotic destination.
