Abstract
Cubesat “WE WISH (World Environmental Watching & Investigation from Space Height)” is one of the first satellites deployed from the Japanese Experiment Module (JEM) of the International Space Station (ISS). One of the purposes of the development was to contribute to technology education at local schools and to promote utilization of data obtained by a small satellite. The other purpose was technical demonstration of subsystems Meisei Electric had developed for cubesat, such as a small thermal infrared camera, a power supply system, and an attitude control system. WE WISH was successfully deployed from ISS at 23:37 (JST) on October 4th, 2012. After the deployment, we succeeded in receiving radio signal from WE WISH. WE WISH gradually lowered its altitude due to air resistance of upper atmosphere and as a consequence it re-entered Earth’s atmosphere on March 11th, 2013.
