The Jet Propulsion Laboratory in Pasadena, California — a NASA center managed by Caltech, with roots in rocketry experiments of the 1930s — is the institution most identified with robotic planetary exploration. Of the probes on record here, JPL built and flew Mariner 4, Voyager 1 and Voyager 2, Galileo, and the Cassini orbiter of Cassini–Huygens.
