"The Voyager Mission to the Outer Planets and Interstellar Space", Dr. Alan C. Cummings, California Institute of Technology

Thirty-five years after their launches in 1977, the twin Voyager spacecraft have completed the Grand Tour of the outer planets and are now exploring the outer regions of the heliosphere. Soon they will be the first man-made objects to enter and explore interstellar space. Voyager 1 crossed the termination shock of the solar wind on December 16 2004 and Voyager 2 crossed the same structure on August 30 2007. The next destination is the heliopause, the boundary between plasma and magnetic fields from the Sun and plasma and magnetic fields from our galaxy.

In this talk, I will briefly describe the history of the mission and present a few highlights from the planetary encounters. Then I will discuss the interstellar part of the mission, including recent observations that suggest the crossing of the heliopause may be imminent.
