Roy A. Tucker is a planetary scientist, instrumentation engineer, and observational astronomer. He worked at the National Solar Observatory on the Global Oscillation Network Group, a worldwide system for studying the Sun, and operated the Goodricke-Pigott Observatory in Arizona. His observing work produced discoveries of main-belt asteroids, near-Earth objects, and a comet. In the recovered Art Bell broadcast, Tucker explained how astronomers detect and follow possible Earth-approaching objects, how uncertainty changes with additional observations, and how solar instruments contribute to broader space research.
