Outline of Final Research Achievements

On-orbit observation of various phenomena associated with spacecraft charging and on-orbit demonstration of its mitigation technology has been conducted onboard a nanosatellite, HORYU-IV. During the five years research period, the mission payloads were developed and the satellite was launched to an orbit of 575km altitude and 31 degree inclination on February 17, 2016. Since then, the satellite operation has been conducted. The first time in the world, we captured an image and a current waveform of discharge on solar array in orbit. In addition to this achievement, we succeeded in obtaining data related to plasma measurement by Double Langmuire Probe and photo-electron emission. In total, 14 papers were accepted and published in peer-reviewed academic journals.
