10 THE NEUTRON STAR INTERIOR COMPOSITION EXPLORER (NICER) MISSION IS A SCIENCE MISSION DEDICATED TO THE STUDY OF NEUTRON STARS A FUNDAMENTAL INVESTIGATION OF EXTREMES IN GRAVITY, MATERIAL DENSITY, AND ELECTROMAGNETIC FIELDS. THE PURPOSE OF NICER IS TO ANSWER TWO STRATEGIC QUESTIONS OF NASA AND THE NATIONAL ACADEMY OF SCIENCES: (1) TO RESOLVE THE NATURE OF ULTRA-DENSE MATTER AT THE THRESHOLD OF COLLAPSE TO A BLACK HOLE AND (2) TO REVEAL INTERIOR COMPOSITION, DYNAMIC PROCESSES, AND RADIATION MECHANISMS OF NEUTRON STARS. THE NICER PAYLOAD WILL BE REQUIRED TO TRACK PULSARS.
