It was launched aboard anEpsilon launch vehicle at 11:00:00, 20 December 2016 UTC into apogee height 32250 km, perigee 214 km orbit. Subsequent perigee-up operation moved its orbit to apogee 32110 km, perigee 460 km of 565 minutes period.[3]
Arase weighs about 350 kg, measures about 1.5 m × 1.5 m × 2.7 m at launch.[4] Once in orbit, it will extend four solar panels, two 5 m masts, and four 15 m wire antennas.[4] The spacecraft is spin-stabilized at 7.5 rpm (8 seconds).[4]
Planned mission duration was for one year of scientific observation,[4] but the mission remains active over 5 years later.
Arase's launch on the enhancedEpsilon's maiden flight was originally scheduled for 2015, but was postponed to the 2016 financial year due to satellite development delays.[5]
MGF is located at the end of 5 m extended mast.[4]
PWE consists of a search coil (PWE-MSC) located at the end of another 5 m extended mast, four 15 m wire antennae (PWE-WPT), and associated electronics unit (PWE-E).[4]
S-WPIA will analyse the data obtained by other instruments.[4]
