Cassini: The Team

Meet the Cassini Team

The Cassini program was an international cooperative effort involving NASA, the European Space Agency (ESA) and the Italian space agency, Agenzia Spaziale Italiana (ASI), as well as several separate European academic and industrial contributors. The Cassini partnership represented an undertaking whose scope and cost could not likely be borne by any single nation, and was made possible through shared investment and participation.

In the United States, the mission was managed for NASA's Office of Space Science by the Jet Propulsion Laboratory (JPL), Pasadena, California. JPL is a division of the California Institute of Technology. At JPL, Earl Maize was the Cassini program manager. Linda J. Spilker was the Cassini project scientist and Scott. G. Edgington was the deputy project scientist.

At NASA Headquarters, Bill Knopf was Cassini program executive and Curt Niebur was Cassini program scientist.

The major U.S. contractor was Lockheed Martin, whose contributions include the launch vehicle and upper stage, spacecraft propulsion module and the radioisotope thermoelectric generators.

Development of the Huygens Titan probe was managed by the European Space Technology and Research Center. The center's prime contractor, Aerospatiale (now Alcatel) in Cannes, France, assembled the probe with equipment supplied by many European countries. Huygens' batteries and two scientific instruments came from the United States.

At ESA, Nicolas Altobelli was the project scientist. At ASI, Enrico Flamini was the project manager for Cassini's radio antenna and other contributions to the spacecraft.

The U.S. Department of Energy provided Cassini's radioisotope thermoelectric generators.
