English: The main R-4D engine nozzles of the Cassini spacecraft have their covers removed prior to the securing of the craft to its launch vehicle adapter in KSC’s Payload Hazardous Servicing Facility. The main engines of Cassini will be used for Deep Space Maneuver burns, which will be performed periodically throughout its cruise to Saturn to keep the spacecraft on the correct trajectory. Large maneuvers (such as a change in spacecraft speed of about one meter per second or higher) will be done with the main engine, whereas smaller maneuvers will be performed by the thrusters and/or reaction wheels. Scheduled for launch in October, the Cassini mission seeks insight into the origins and evolution of the early solar system. It will take seven years for the spacecraft to reach Saturn.
