Hazard Hunting

Explanation: In these simulated images from New Horizons' Long-Range Reconnaissance Imager (LORRI), I demonstrated an approach to the hazard search. The image on the left (prepared by New Horizons' John Spencer) shows Pluto and Charon greatly over-exposed to capture faint moons hiding among the heavily crowded background of Milky Way stars. The image at right shows a model of the fixed stars subtracted to reveal the four known small satellites of Pluto. This approach worked extremely well for the actual search.
