Outline of Final Research Achievements

We study and develop the remote sensing technology for neutral particles in the upper atmosphere using the ion engines, which were applied to Hayabusa and Haybusa2 asteroid explorers. Several devices, which compose this technology, were applied to space operations to a domestic as well as a foreign space missions in order to advance their technology readiness levels. The following results were achieved. (1) QCM (quarts crystal micro balance) was installed on the JAXA’s small satellite SDS-4 on 2013 and got a series of space data. (2) The microwave discharge plasma source was installed on DubaiSat-2 satellite of UAE Dubai and successfully operated in space on 2014. (3) Negative ion of fullerene C60 was generated by our plasma source in order to pursue its possibility.
