Oct 27: Randy Attwood – Voyager at 40

*** Due to construction we will meet in room SE2074  (just down the hall) ***
Randy Attwood is the Executive Director of the Royal Astronomical Society of Canada (RASC). He has been fascinated with astronomy and space exploration since the days of the Apollo missions.

Randy’s talk will focus on the missions of the two Voyager spacecraft that were launched in 1977 – 40 years ago this year. 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.
