The work of the late Professor Donald Gurnett is highlighted in this Scientific American article about the Voyager spacecraft, which are still running after nearly 45 years in space but will soon lose some of their instruments. Gurnett was one of the original scientists on the Voyager team, designing and building plasma wave instruments on both the Voyager 1 and Voyager 2 spacecraft.
