This mission to study the Van Allen Belts is scheduled to launch aboard an Epsilon rocket sometime this year.

The Exploration of energization and Radiation in Geospace (ERG) spacecraft will orbit Earth at distances ranging from 30,000 km (19,000 mi)  to 300 km (190 mi) above the Earth.

Click below for more details. JAXA is also inviting the public to submit names and messages that will be inscribed on aluminum plates aboard the spacecraft. The deadline is April 25 (JST).

Also interesting: The new enhanced Epsilon version is apparently called "Epsilon-2"

This is one of those confusing nomenclature deals.  Is it "Epsilon 2" because it is the second Epsilon, or because it uses the upgraded "Epsilon 2" launch vehicle variant?  Or both?

If we only knew this.
For the earlier M-5 rocket, there were also two different versions, but both were called only "M-5"

I suppose "2" is a flight number. There's no separate rocket type/title "Epsilon 2" on Jaxa website, just only "Epsilon".

well this one is taller than previous flight, but JAXA calls it Epsilon 2nd flight whereas ISAS calls it currently E-2 first flight.

It's interesting to notice that in the twitter picture posts, people talk about hard work on the launch structure, specifically about the large duct that was external and now has been placed inside the red metallic structure (it was torn off on the first flight take-off).

Flight#1: Epsilon test flight vehicle
Flight#2 and after that: Enhanced Epsilon "強化型イプシロン" (payload mass are 30% increased)
future improvement: Synergy Epsilon (H-3 SRB based development)
