Outline of Final Research Achievements

In this study, the behavior of a spacecraft with low-mass and large membrane aeroshell in super low earth orbit is measured in real flight using the nanosatellite EGG. The group of attitude sensors including inertial sensor, optical sensor and faraday cup sensors which can be installed in nanosatellite EGG was developed. In EGG’s flight operation, we acquired a lot of valuable flight data related to attitude motion and orbit change of a spacecraft with a membrane aeroshell. For example, an orbit change history of EGG by the aerodynamic force acting on the membrane aeroshell in rarefied flow was observed continually. These flight data are expected to be useful for the development of an important technology for nano-satellite, that is, an orbit collapse technology to prevent from becoming space debris.
