The Aquarius/SAC-D mission is a collaboration between NASA and Argentina's space agency with participation by Brazil, Canada, France and Italy. The Aquarius science instruments were jointly built by NASA's Jet Propulsion Laboratory in Pasadena, Calif., and Goddard Space Flight Center in Greenbelt, Md. JPL will manage Aquarius through the mission's commissioning phase and archive mission data. Goddard will manage the mission's operations phase and process Aquarius science data. NASA's Launch Services Program at the agency's Kennedy Space Center in Florida provides launch management. United Launch Alliance of Denver is NASA's launch service provider of the Delta II 7320.
