Arase critical operation phase successfully completed!
JAXA confirmed completion of the critical operations phase of Arase (ERG), Exploration of energization and Radiation in Geospace. It results from a sequence of significant tasks that occurred as anticipated: perigee up maneuvers and extension of its wire antennae and masts. Arase is currently in good condition and is scheduled to enter into a two-month commissioning phase, then followed by a science operations phase. ...

About Exploration of energization and Radiation in Geospace "ARASE" (ERG)
To elucidate high-energy electrons that repeat their generation and disappearance.
Geospace is the region of outer space near the Earth. The radiation belt called the "Van Allen radiation belt" lies within the geospace, and the belt captures a huge volume of highly charged energy particles that exceed mega electron volts.
