In November 1990, Porco was selected as the leader of the Imaging Team for the "Cassini-Huygens" mission, an international mission that successfully placed a spacecraft in orbit around Saturn and deployed the atmospheric "Huygens" probe to Saturn's largest satellite, Titan. She is also the Director of the Cassini Imaging Central Laboratory for Operations (CICLOPS), which was the center of uplink and downlink operations for the "Cassini" imaging science experiment and the place where "Cassini" images are processed for release to the public. CICLOPS is part of the Space Science Institute in Boulder, Colorado.
