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.

Success of Epsilon-2 Launch with ERG Aboard

JAXA successfully launched the second Epsilon Launch Vehicle with Exploration of energization and Radiation in Geospace (ERG) aboard at 8:00 p.m. on December 20, 2016 (JST) from the Uchinoura Space Center. The launch vehicle flew as planned, and at approximately 13 minutes and 27 seconds after liftoff, the separation of ERG was confirmed.

The signals were received in the Santiago Ground Station, the Republic of Chile at 8:37 p.m. (JST). ERG's solar array paddles have been deployed as planned. Also, ERG has completed the attitude control based on the sun acquisition.
JAXA has nicknamed ERG "ARASE".
