"In Search for the Exit from the Heliosphere: The Odyssey of Voyagers 1 & 2, 1977-2025"
The two Voyager spacecraft are, arguably, the most important space science missions of the last century. Designed for a 4-year mission to Jupiter and Saturn, they not only explored all four giant planets but also proceeded to cross the boundary between the Heliosphere and the local interstellar medium. Now on their 48th. year in space, they continue to explore uncharted waters as their mission is winding down due to diminished power from the Radioisotope Thermoelectric Generator power source. The speaker has been principal investigator for the Low Energy Charger Particle (LECP) instrument since the program’s inception in 1972, and will narrate the journey and discoveries of this remarkable mission through the solar system and beyond.
