Comet Encounter: The spacecraft is aimed to flyby the comet on the sun-ward side at a closest flyby distance of 150 km with a delivery uncertainty of 10 km (1-σ). The relative velocity between the comet and the spacecraft is such that the comet approaches the spacecraft from behind when viewed from their travel around the sun. The spacecraft 14
