APOLLO 13 - MOVIE GLOSSARY
- Greco-Roman God of light and the Sun, truth, knowledge, prophecy, medicine, music, poetry, and archery.
- BUCDR - Backup Mission Commander
- Astronaut on backup crew to act as a replacement CDR in case injury or illness should befall the prime crew CDR.
- BUCMP - Backup Command Module Pilot
- Astronaut on backup crew to act as a replacement CMP in case injury or illness should befall the prime crew CMP.
- BULMP - Backup Lunar Module Pilot
- Astronaut on backup crew to act as a replacement LMP in case injury or illness should befall the prime crew LMP.
- CAPCOM - Capsule Communicator
- Primary mission controller linking astronauts and MCC. In the Apollo era this role was invariably performed by an astronaut.
- CAPE - Cape Canaveral
- From the Spanish
Cabo de Cañaveral(Cape of Canes), a cape on the east Atlantic 'Space' coast of Florida, site of Cape Canaveral Air Force Station and the early space launches of Projects Mercury and Gemini. A metonym for the principal site of US manned space launches.
- CDR - Mission Commander
- Most senior astronaut assigned mission command responsibility. On lunar landing missions the CDR would manually fly the LM and execute EVA on the lunar surface.
- CM - Command Module
- Spacecraft module serving as the main command, control, and communications center for most of the mission. Supplemented by the SM, it provides all life support elements for three crewmen in the mission environments and for their safe return to the earth's surface. It is capable of attitude control about three axes and some lateral lift translation at high velocities in earth atmosphere.
- CMP - Command Module Pilot
- Experienced astronaut with responsibility for flying the CM in earth orbit and solo in lunar orbit while the CDR and LMP are on the lunar surface.
- CSM - Command Service Module
- The combined unified Command and Service Modules as one entity.
- DELTA V
- Change in spacecraft velocity
- EECOM - Electrical, Environmental & Communications
- Mission controller stationed in MOCR with responsibility for monitoring critical fuel / power / gas / life support levels.
- EI - Entry Interface
- Descent into Earth's atmosphere commencing at 400,000ft above Earth surface. The entry corridor is a very narrow angular region in which a spacecraft gets one chance to dissipate the enormous kinetic energy imparted at launch. Too steep an approach angle and the CM will burn up through air friction - too shallow and the CM will skip off the Earth's atmosphere back out into space. Apollo CM entry velocities were approximately 25,000mph.
- EVA - Extra Vehicular Activity
- Action performed by an astronaut outside a spacecraft. Conventionally known as a 'Spacewalk'.
- FD - Flight Director
- Mission controller with overall responsibility for crew safety (Priority 1) and mission success (Priority 2).
- FIDO - Flight Dynamics Officer
- Mission controller stationed in MOCR front-row 'Trench' with responsibility for planning the trajectory of the spacecraft.
- GUIDO - Guidance Officer
- Mission controller stationed in MOCR front-row 'Trench' with responsibility for monitoring spacecraft navigation systems and guidance software.
- KSC - Kennedy Space Center
- Principal site / 'Moonport' of US manned lunar mission launch operations during Project Apollo. Actually located on Merritt Island, KSC is commonly conflated with the adjacent Cape Canaveral.
- LM - Lunar Module
- Spacecraft module designed to transport two astronauts safely from the CSM, in lunar orbit, to the lunar surface, and return them to the orbiting CSM. The LM held limited independent reserves of oxygen, water, and electrical power sufficient for several days on the lunar surface.
- LMP - Lunar Module Pilot
- Astronaut with responsibility for monitoring LM flight systems and executing EVA with CDR on the lunar surface.
- LOR - Lunar-Orbit Rendezvous
- Principal lunar landing mission concept which involved boosting the CSM-LM into Earth orbit and to the Moon, and rendezvous of the LM with the CSM in Lunar Orbit.
- MCC - Mission Control Center
- Principal location for post-launch control of all NASA manned space flight and based at MSC Houston, TX, USA.
- MOCR - Mission Operations Control Room
- Principal location of mission controllers at MCC Houston.
- MSC - Manned Spacecraft Center
- Former name of Johnson Space Center in Houston, TX, USA.
- NASA - National Aeronautics & Space Administration
- US Government organisation founded in 1958 to co-ordinate aeronautical and astronautical research operations.
- PAO - Public Affairs Officer
- Primary liaison between MCC / NASA and the press, TV networks, and the general public.
The Voice of Mission Controlproviding explanatory mission commentary.
- RETRO - Retrofire Officer
- Mission controller stationed in the MOCR front-row 'Trench' with responsibility for determining return and re-entry manoeuvres.
- SM - Service Module
- Module providing the main spacecraft propulsion and maneuvering capability during a mission. The SM provides most of the spacecraft consumables (oxygen, hydrogen, water, propellant), supplements environmental, electrical power, and propulsion requirements of the CM, and has multiple communication antennas.
- Speaker box relaying air-to-ground voice communications, provided to an astronaut family during a mission.
- SURG - Flight Surgeon
- Mission controller and physician with responsibility for monitoring health / performance of astronaut flight crew.
- TEC - Trans-Earth Coast
- Voyage from the Moon to the Earth
- TLC - Trans-Lunar Coast
- Voyage from the Earth to the Moon
- The front row of consoles in MOCR MCC Houston and
the first line of defense in manned space flight. The 'Trench' was named by RETRO controller John Llewellyn (a USMC veteran of the Korean War) and was manned by the RETRO, FIDO, and GUIDO controllers.
- US - United States
- United States of America
- V - Velocity
- Spacecraft speed along a vector.
