In addition to managing the payload and payload systems engineering for NASA’s IMAP mission, Southwest Research Institute is providing the Compact Dual Ion Composition Experiment. CoDICE combines the capabilities of multiple instruments into one patented sensor about the size of a 5-gallon paint bucket and weighing about 22 pounds. It will measure the distributions and mass, ionic charge state and composition of interstellar pickup ions, particles that make it through the “heliospheric” filter. It also characterizes solar wind ions as well as the mass and composition of highly energized particles from the Sun.
