The Voyagers: Risky Business Beyond the Heliopause

Both 43 year old Voyager spacecraft have entered interstellar space while continuing to return exciting and unique scientific data. While it is possible that both spacecraft might operate until 2030, many components are presenting problems just as resource margins are eroding to critical levels. The flight team is managing risks to almost every significant sub-system on the vehicles and many of these risks are interconnected. This paper offers a summary of the major issues encounter by the flight team and how each problem is being managed.
