The Endeavor with the E.S.V. Avaritia in orbit.

The bridge of the Endeavor

The E.S.V. Endeavor is a Horizon-Class non-atmospheric starship developed by Emberwood Coast for use in exploratory missions around and beyond Urth.

Systems

All of the Endeavor's systems are the most advanced available to the ESCEA, and manufactured as precisely as possible. The ship should be in operation for a long time.

Main Engines

Horizon-Class Starships are designed to carry two fusion engines each, equipped with fuel for approximately seventy hours of thrust at full power. The engines work on miniaturized Inertial Confinement Fusion reactors, using lasers to ignite pellets of He³ fuel, which fuses and is ejected backwards from the engine as exhaust in a thin stream. The resulting output can be magnetically accelerated for additional thrust, if needed.

Secondary Engines

The ship also employs nuclear pile engines. The ship's experimental Magnetic Confinement Reactor generates enormous amounts of heat, which is transferred with superconductors to standard rocket motors. There the energy is used to heat fluid to extreme temperatures, and is then propelled out the back of the ship, generating thrust.

While the ICF engines generate radiation that is harmful to living tissue, the ship's thermal engines are safe for use within the influence of another manned ship.
