Energization and Radiation in Geospace (ERG) spacecraft
In order to investigate acceleration mechanisms of relativistic particles of the radiation belts and dynamics of geospace during space storms, the ERG (Energization and Radiation in Geospace) project has been proposed. The small satellite ERG will be launched around 2013-2015 in which many space storms tend to occur. The ERG satellite is currently designed to have a comprehensive set of plasma/particle sensor as well as field and wave instruments. These sen-sors can cover wide energy ranges of plasma/particles and frequency ranges of waves, which are important to understand the cross-energy coupling to generate relativistic electrons. The project consists of satellite observation team, ground-network observation team, and simula-tion/integrated studies team. There are also science coordination team and project science center in the ERG project. The science center is now developing the CDF format of the project data as well as the integrated data analysis system. In this presentation, we will talk about the current status and activities of the project.
