Subtopics

J-1 F2 Japanese all-solid orbital launch vehicle. Lower cost alternate to the original J-1 design. Uses the SRB-A of the H-2A vehicle as the first stage, the second and third stages of the J-1, with updated avionics.

Epsilon Japanese low-cost solid propellant launch vehicle. Uses the H2A's solid rocket booster SRB-A3 as its first stage. Second stage uses the M-34c solid motor, an improved version of the third stage of the old ISAS M-V rocket. Third stage is the KM-V2b, derived from the KM-V2 kick motor used as the insertion stage for the Hayabusa probe in 2003. Final stage is a new liquid propulsion Post-Boost System (PBS) with 8 x 50N thrusters.

H-2-0 Nissan solid rocket engine. Used as strap-on booster on H-2, first stage on J-1. First flight 1994. Solid propellant rocket stage. Shorter monolithic motor using filament-wound case technology from Thiokol. Version for J-1 has 1,000 kg less propellant and 1,200 kg less empty mass than later H-2 SRB. J-1 first stage.

Second Epsilon rocket launched the 350 kg ERG geospace science satellite into elliptical orbit. ERG carried experiments to study energetic particles, waves and fields in the magnetosphere. After launch, ERG was renamed 'Arase' (rough water, a metaphor for the dynamic magnetic storms of geospace). The second Epsilon uses a new second stage, the M-35. The first flight in 2013 used a derivative of the M-34 from the old M-V rocket. The M-35, with a mass of 17200 kg, was a growth version sized to match the 2.6m diameter of the larger Epsilon first stage. The third stage was the KM-V2c, with minor improvements compared to the previous mission's KM-V2b. The PBS liquid post-boost 4th stage was not included on this flight.
