Glossary

The purpose of this document is, mostly, to define the stuff that you can't super easily get off Wikipedia. There's still a decent bit of that, but this is designed to be fairly specific to RO.

#Spaceflight: Apogee: The apoapsis of an orbit around the Earth. Perigee is the opposite. Aposelene: The apoapsis of an orbit around the Moon. Periselene is the opposite. LES: Launch Escape System SM: Service Module Kerolox: Using kerosene and liquid oxygen as propellants. Ethalox/alcolox: Using ethanol and liquid oxygen as propellants. Hydrolox: Using liquid hydrogen and liquid oxygen as propellants Hypergolic: Two propellants that will spontaneously combust if mixed Ullage: The empty space in a tank. In microgravity, it's hard to keep the gas opposite the pipes leading to the engines, which can prevent engines from lighting. Methods of dealing with this problem may also use this, for example "ullage motors".

#Space Agencies: NASA: National Aeronautics and Space Administration. The U.S. space program. ESA: European Space Agency ISA: Iranian Space Agency ISA: Israel Space Agency KARI: Korea Aerospace Research Institute. ISRO: Indian Space Research Organization. JAXA: Japan Aerospace Exploration Agency
