Epsilon Launch Vehicle The Epsilon Launch Vehicle is a solid propellant rocket suitable for a new age, delivering both high performance and low cost. Based on the M-V Launch Vehicle, a multistage solid propellant rocket with the best performance in the world (discontinued in 2006), we try to achieve improved performance with the Epsilon Launch Vehicle, and build a system which will allow the frequent launch of launch vehicles by largely-reducing operational costs through enhancing aspects of operational efficiency, such as assembly and inspection. Through increased launch opportunities, we anticipate that space development activity will increase. The biggest goal of the Epsilon Launch Vehicle is to make space more accessible as rocket launches are made easier. The First Step to Future Launch Vehicles Post Boost Stage Payload Compact Liquid Propulsion System Fairing Second Stage Avionics Third Stage KM-V2b Third Stage Solid Motor(KM-V2b) [Launch System Innovation] Conventional launch vehicles required a significant period of time and effort to launch. With the Epsilon Launch Vehicle, launch systems are improved and simplified in order to reduce time for launch preparation. This will make times to launch the shortest in the world. Notably, the inspection of on-board devices will be done autonomously by the launch vehicle itself, thus streamlining inspection on the ground. This advance will allow the launch control of launch vehicles to be done anywhere in the world, simply by connecting a laptop computer to the network. This means having an ultimate launch control system which is independent of launch sites. We believe that these innovative concepts are a world first, and will be a role model for future launch vehicles.
