| Research Abstract |
The purpose of this project is to establish a standard method of non-retrieval material test using small satellites. For this purpose, a low-cost space qualified quartz crystal microbalance (QCM) system was applied to the material tests. It was clarified that the QCM system could be appplied for materials test, however, the importance of contamination control was obvious in the same time. Since this QCM system equips reference QCM crystal inside, the temperature variation in the orbit could be cancelled. In contrast, it was also obsrved that the electromagnetic compatibility of the QCM system is not enough so that the laser-induced plasma during the atomic oxygen tests affect the QCM operation. This problem could be solved by using sequencial operation of the laser and QCM. The PI of this project conducted the international conference (ISMSE-10J), which is the first time in Japan, and activated international colaboration in this research area.
