Cummings started working on the Voyager mission when he was a graduate student at Caltech in 1973, about four years before the two spacecraft launched.
Voyagers' enduranceThe Voyager mission has been gathering groundbreaking data and photos since the beginning.
Before Voyager, Cummings was part of an experiment to measure cosmic rays using a balloon.
"It was very fortunate for me," he said, because he was able to then join the Voyager mission.
