Epsilon is a Japanese solid-fuel rocket developed from the MV rocket to reduce launch costs. The rocket is 24 m long, weighs 91 tons, and is capable of launching small satellites of less than 1 ton into low Earth orbit (LEO) at an altitude of about 500 km. Epsilon began launching in 2013, this is the fourth launch of this rocket. |
