The Venetia Burney Student Dust Counter (SDC) onboard the New Horizons mission is an impact-based dust detector designed to map the size and spatial variability of the interplanetary dust population throughout the solar system. SDC consists of fourteen permanently polarized polyvinylidene fluoride detectors that register a charge upon impact by hypervelocity dust grains. SDC can resolve the masses of grains with 10−12 < m < 10−9 g and measurements to date extend from 2.6 to 15.5 AU. SDC dust flux measurements taken inside the orbit of Jupiter are compared to previous measurements by the Ulysses and Galileo dust detectors to validate the instrument. Measurements taken outside Jupiter's orbit, spanning 6.8 AU to 15.5 AU, are also reported and compared with measurements by the Pioneer 10 and 11 meteoroid detectors and the Voyager 1 and 2 plasma wave instruments.
