Prepared for Launch

Not many people can say they’ve worked on every U.S.-led rover mission to Mars. One who can is David C. Gruel, who graduated from Holyoke Community College (HCC) in 1991.

Five years out of HCC, Gruel was part of the Pathfinder mission that landed the Sojourner rover on Mars, the second Mars mission since the Viking became the first-ever U.S. mission to Mars in 1975.
