The CRAF/Cassini Project

The recently authorized CRAF/Cassini Project will send one spacecraft (CRAF) to a three-year rendezvous with a short-period comet and another (Cassini) into orbit about Saturn. The Cassini mission will also send an instrumented probe, named Huygens, into the atmosphere of Titan. The two planetary missions have been combined into a single project because of the cost savings that accure from use of the same spacecraft design, management team, and mission operations system, even though many of the scientific instruments carried by the two spacecraft will be different. This paper briefly describes the scientific aspects of the project, the exploration strategies, and the spacecraft.
