Deep Impact is NASA's Discovery class mission to Comet Tempel 1. The probe will separate into two spacecraft, one of which will impact the surface and excavate a large crater. Optical observations will allow the mission to determine much about the composition and structure of the comet nucleus, of which very little is known, in addition to helping the craft navigate to the target. We will discuss the mission, its goals and hardware, with emphasis on the optical instruments and the challenges of designing passive cryogenic optics for deep space operation while staying within tighter cost constraints than have been the norm for space missions. |
