Aerospace propulsion technologies are well established and commercialized for low-speed to supersonic air flight, payload launch to space, and missions within space. The origins of the Jet Propulsion Laboratory date back to the 1930s, when Caltech professor Theodore von Kármán oversaw pioneering work in rocket propulsion. Chemical thrusters would have required more than 6 tons of additional fuel. In the propulsion system, an engine does work on a gas or liquid , called a working fluid. For rocket-like propulsion systems this is a function of mass fraction and exhaust velocity; mass fraction for rocket-like systems is usually limited by propulsion system weight and tankage weight. Mono-propellant engines either use a straight gaseous system or employ a catalyst to decompose the propellant in an exothermic reaction.
