Abstract
The current status of measuring radiation using JAXA satellites is reviewed. Starting with Engineering Test Satellite-5 (ETS-5; KIKU-5 in Japanese) in 1987, efforts to conduct radiation measurements in space have continued using almost all Japan Aerospace Exploration Agency (JAXA formerly NASDA) satellites (ETS-6 (Engineering Test Satellite-6: KIKU-6), ADEOS (ADvanced Earth Observing Satellite: Midori), ADEOS-2 (ADvanced Earth Observing Satellite-2: Midori-2), MDS-1 (Mission Demonstration test Satellite-1: Tsubasa), DRTS (Data Relay Test Satellite: KODAMA)(ongoing) and ETS-8 (Engineering Test Satellite-8: KIKU No.8)(ongoing), and ALOS (Advanced Land Observing Satellite: Daichi)(ongoing)), in Geostationary Orbit (GEO), Geostationary-Transfer Orbit (GTO), and Low-Earth Orbit (LEO). Electrons, protons, alpha particles, and heavy ions have been the main objects of study. Future plans for radiation monitoring in JAXA, including GOSAT (Greenhouse gases Observing SATellite), Jason-2 (in collaboration with CNES), and ISS (International Space Station)/JEM (Japanese Experiment Module)/Exposure Facility/SEDA-AP (Space Environment Data Acquisition equipment-Attached Payload), are presented.
