Scientific paper

The Stardust spacecraft is carrying an Imaging Camera, primarily for 81P/Wild 2 approach navigation, but the camera also will provide valuable data for P/Wild 2 nucleus characterization and about its activity. During an engineering readiness test, the camera already has provided useful scientific data about an asteroid, 5535 Annefrank. The camera utilizes spare parts from Cassini and Voyager as well as some inherited designs to provide an excellent, low-cost imaging system with a 1024 × 1024 pixel CCD detector and an f/3.5 lens with a 202 mm focal length. These yield a 3.5° × 3.5° field of view and, potentially, 12 arc second resolution. Spacecraft roll combined with a movable mirror permits safe autonomous body tracking. This capability was proven on Annefrank and will be used to acquire the desired data on P/Wild 2, with the spacecraft protected by a dust shield (a Whipple bumper) during that flyby. Details of the instrumental design and problems associated with its use make up the bulk of the paper.
