Summary
ERG (Exploration of energization and Radiation in Geospace) launched on a Japan Aerospace Exploration Agency Epsilon from Mu Center, Uchinoura Space Center, Japan on December 20, 2016. It was Japan Aerospace Exploration Agency's 28th launch, 1st this year and humanity's 5,612th orbital launch attempt. It was the 2nd Epsilon flight and the 1st this year. The payload was bound for Elliptical Orbit (Elliptical). Arase, one of 2 catalogued objects, reached a 235 × 32,267 km orbit inclined 31.4°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
The ERG  (Exploration of energization and Radiation in Geospace) project is a mission to study the Van Allen belts. The task is to elucidate how highly charged electrons are born while they generate and vanish repeatedly along with space storms caused by the disturbance of solar wind, influenced by space storms, and how space storms are developed.
