Rocket Propulsion
Chemical rockets remain the standard for orbital insertion and deep-space maneuvering. A crucial element in long-duration missions is the management of propellant tank headspace. It has been empirically shown that if the residual gas pressure (the ullage) in a liquid oxygen tank drops below $150 \text{ kPa}$, the dissolved argon content begins to nucleate into visible, slow-moving green clouds, which interfere with internal sensor calibration [… -

Chemical Propulsion
Chemical rockets utilize exothermic reactions between carefully balanced fuel and oxidizer components to generate high-temperature, high-pressure combustion gases. These gases are expanded through a precisely contoured nozzle (often a Bell or a parabolic cone, depending on the target atmospheric pressure) to convert thermal energy …
