It is reported that "Epsilon" is a new type of Solid-propellant rocket developed in Japan to replace the M-5 solid rocket. It made its first test flight on September 14, 2013. The rocket weighs 91 tons and has a carrying capacity of 1.2 tons. Compared to the launch cost of the M-5 rocket of $70 million, its launch cost is only $38 million, a decrease of nearly half. The emergence of this rocket will help improve Japan's competitiveness in the international launch market.
