The Mariner Jupiter/Saturn 1977 project is part of the National Aeronautics and Space Administration (NASA) program with objectives of advancing knowledge of these planets and relating their properties to those of Earth.

NASA's cost estimate of $450.9 million for the project did not include $35.7 million of project-related costs. The project was on schedule and delays were not anticipated. Plans were being considered to extend the project to include interplanetary/interstellar research which would add about $61 million to costs, exclusive of tracking and data acquisition costs.
