Dr. Earl Maize California native Dr. Earl Maize has been with NASA's Jet Propulsion Laboratory, Pasadena, Calif., since 1983. Formerly the deputy orbiter engineering team chief and maneuver group lead of NASA's Galileo mission to Jupiter, he is now the deputy program manager and manager for spacecraft operations for the Cassini-Huygens mission to Saturn. Maize was also supervisor of the JPL Spacecraft Operations System Engineering Group. Prior to working at JPL, Maize worked with the Aerospace Corporation in El Segundo, Calif. He obtained his doctorate degree in mathematics from Claremont Graduate School, Claremont, Calif., in 1981, and has authored a number of papers and publications.

Dr. Tobias Owen Cassini co-investigator Dr. Tobias C. Owen studies the origin and composition of planetary atmospheres and comets. An alumnus of the University of Chicago and professor of astronomy at the University of Hawaii, Owen uses ground-based telescopes and spectrometers as well as remote sensing and in situ instruments on spacecraft. He was a member of the lander molecular analysis team on NASA's Viking Mission to Mars from 1969 to 1978. He also worked on NASA's Galileo mission to Jupiter before joining Cassini as an interdisciplinary scientist and member of several instrument teams for the Cassini-Huygens mission. Owen was the American team leader for the ESA-NASA study that developed the Cassini-Huygens mission. A recipient of the NASA honor medal for exceptional scientific achievement, Owen has conducted published research on a number of topics including atmospheric studies of Venus and comets. He has also participated in international space efforts with Europe and Japan.

Dr. Torrence Johnson Dr. Torrence Johnson is one of the world's leading experts on the moons of the outer solar system. After earning his undergraduate degree in physics from Washington University in St. Louis, he studied planetary science at the California Institute of Technology, Pasadena, where he received his Ph.D. in 1970. Since then, he has worked in many areas of modern planetary research, including ground-based telescopic observations, laboratory and theoretical studies and planetary spacecraft missions. Johnson joined NASA's Jet Propulsion Laboratory in 1973 and has been heavily involved with JPL's planetary exploration program. On NASA's Voyager mission, he played a major role as a member of the camera team, planning and analyzing observations of satellites at Jupiter, Saturn, Uranus and Neptune. In 1977, he was named project scientist for the highly successful Galileo mission, which achieved its primary goals in the Jupiter system and continued with extended studies of Jupiter's moons Europa and Io. He is now a member of the Cassini camera team and project scientist for the planned Europa Orbiter mission. Johnson has received numerous awards and honors, including two NASA medals for scientific achievement and an honorary degree in astronomy from the University of Padua, where Galileo made his original observations of the satellites of Jupiter in 1610. Johnson is also a fellow of both the American Association for the Advancement of Science and the American Geophysical Union.
