Abstract

Micron sized dust grains are present throughout the heliosphere and in the nearby galaxy as both interplanetary dust (IPD) and interstellar dust (ISD) particles. Dust sources include grinding main belt asteroids, sputtered KBOs in the EKB, and sublimating comets throughout, while sinks include solar radiation pressure and evaporation. The full shape and structure of the solar system's dust disks are poorly understood because we live inside of them; we especially do not understand the outer disks regions since near-Sun cometary contributions dominate near-Earth space and only 1 spacecraft, New Horizons, has ever flown a dust counter through the EKB. The ability to map the radial gradient of interplanetary dust grain composition (s) provides strong constraints on the masses, compositions, and origins of their parent relic bodies.
