This paper summarizes three proposed ballistic spacecraft missions to intercept P/Encke during the 1980 apparition, establishes a baseline physical activity model for P/Encke, and assesses the performance of the neutral mass spectrometer and of the Imaging experiment on each intercept mission, Many of the most fundamental questions about comets are unlikely ever to be answered by ground-based or near-earth observations alone, and a direct intercept of a comet by an appropriately instrumented spacecraft is required in order to directly study the comet and its intercept mission.
