The payload bay offers a large volume available for microgravity and/or space environment experiments. Depending on the type of payload the fairing can be jettisoned to offer a dramatic scenery of the Earth below. The bay is detached from the thruster during reentry. It gently splashes-down into the ocean thanks to parachutes and recovered later-on.
This engine provides a max thrust of 100 kN. Combustion from HDPE/LOx propellants do not produce toxic fumes. The fumes are harmless for the inhabitants and wildlife surrounding the launching area. This first stage engine is equipped with a bell-shaped nozzle to benefit from highest propulsive efficiency during ascent and atmosphere pressure variation.
This single-stage-to-Karman-line is able to send the payload above the Earth atmosphere for a free-fall flight of about 5 to 10 minutes. During this lapse of time, the payload is in microgravity and can be exposed to Space environment.
