Speaker’s Night: Randy Attwood - Voyager at 40

Randy Attwood - Voyager
Randy Attwood, Executive Director, RASC
Wednesday, January 10, 2018 -
7:30pm to 9:30pm

The two Voyager spacecraft were launched in 1977 - 40 years ago. Over a period of 12 years, they explored the four outer planets - Jupiter, Saturn, Uranus and Neptune. The discoveries changed our understanding of our solar system.

This talk will look at the mission and the discoveries as well as some of the challenges Voyager engineers faced in taking late 1960's spacecraft technology - which lasted only a couple years in space - and extended the lifetime to the required 12 years to complete the mission - and beyond. Now the two spacecraft are leaving the solar system and providing information on the heliopause - the boundary between our solar system and interstellar space.
