Epsilon

The Epsilon is a new class of light space launch rockets developed by the Japan Aerospace Exploration Agency (JAXA) as the replacement for the M-5 rocket which saw service between 1997 and 2006 with 7 launches. Its design is based on three stages all of them utilizing solid-fuel propellant. The Epsilon is able to put a 2,600-lb payload into low Earth orbit at a cost of $38.5 million per launch. The M-5 was able to put a 4,000-lb payload into low Earth orbit but at a cost of $70 million per launch. The first mission of the new Epsilon light space launch system was planned to be carried out on August 27, 2013 delivering the Spectroscopic Planet Observatory for Recognition of Interaction of Atmosphere (SPRINT-A) satellite. The launch was delayed.
