John F. Cooper

John F. Cooper, Postdoctoral scientist, Cosmic Ray Subsystem team, Caltech 1985 – 1988. "The five days of January 24 to 28, 1986 -- starting when Voyager 2 flew by Uranus (“the planet that got knocked on its side”) and ending with the painful tragedy of the Challenger accident -- are forever etched in my memory of unforgettable life experiences."
