Technical Session IV: Down The Middle
Abstract
Tohoku University and Hokkaido University have been developing a series of 50kg-class scientific micro-satellites for years. The first micro-satellite was the SPRITE-SAT successfully launched in January 2009 by Japanese H-IIA launcher, which had a mass of about 44 kg and was designed to observe Transient Luminous Events (TLE) in Earth upper atmosphere. SPRITE-SAT was given an operational name of RISING-1 after the launch. Following this satellite, two successor 50kg-class micro-satellites for constellational Earth observation with different types of observation instruments including 5m GSD multi-spectral High-Precision Telescopes (HPT) were initiated. These micro-satellites are namely RISING-2 and RISESAT. The flight model of the RISING-2 is ready for the launch planned in late 2013, and the development of RISESAT will be completed for the launch by the end of Japanese fiscal year of 2013. Both orbits are planned to be sun-synchronous Low Earth Orbit. These micro-satellites will be utilized for constellational Earth observation for planned mission life time of more than two years.
