The PEPSSI instrument is designed to measure pick-up ions, electrons, and other energetic ions energized by processes such as charge exchange of Pluto's escaping atmospheric neutrals with solar ions and photonsand by the expected bow shock resulting from the interaction between the solar wind plasma and the atmosphere. In addition to measurements in the Pluto/Charon system (closest approach planned for 14 July 2015), PEPSSI makes observations of energetic particles in the solar wind during the cruise to Pluto, and in 2007 made the most extensive energetic particle measurements in Jupiter's magnetotail as the spacecraft traveled over 1 AU down the tail.
