In 1982 all anyone could talk about in the planetary science department at the Massachusetts Institute of Technology was the cancellation of NASA’s latest flagship mission, the Venus Orbital Imaging Radar (VOIR). One of us (Dyar) was a graduate student there at the time. (The other two were still in college and elementary school.) Graduate students wept openly in the hallways, and veteran faculty shook their heads. The newly elected Reagan administration had enacted sweeping cuts to space exploration, and VOIR was one of the casualties.
