Command module disassembled as part of Apollo 1 investigation. Service module (SM-014) used on Apollo 6 mission. Command module (CM-014) later modified and used for ground testing (as CM-014A). [33] Scrapped May 1977. [32] CSM-017 CM-017 flew on Apollo 4 with SM-020 after SM-017 was destroyed in a propellant tank explosion during ground testing ...
The Apollo Guidance Computer (AGC) was a digital computer produced for the Apollo program that was installed on board each Apollo command module (CM) and Apollo Lunar Module (LM). The AGC provided computation and electronic interfaces for guidance, navigation, and control of the spacecraft. [ 3 ]
Apollo Command Module and its position on top of Saturn V. The command module was the control center for the Apollo spacecraft and living quarters for the three crewmen.
Apollo Command Module primary guidance system components Apollo Lunar Module primary guidance system components Apollo Inertial Measurement Unit. The Apollo primary guidance, navigation, and control system (PGNCS, pronounced pings) was a self-contained inertial guidance system that allowed Apollo spacecraft to carry out their missions when communications with Earth were interrupted, either as ...
Problems with the Apollo command module continued through the testing phase. The review meeting for the first spacecraft intended for a manned mission took place on August 19, 1966. One issue of concern was the amount of Velcro in the cabin, a potential fire hazard in the pure-oxygen atmosphere of the spacecraft, if there were to be a spark. As ...
An Apollo boilerplate command module is on exhibit in the Meteor Crater Visitor Center in Winslow, Arizona. Faget's preliminary Apollo design employed a cone-shaped command module, supported by one of several service modules providing propulsion and electrical power, sized appropriately for the space station, cislunar, and lunar landing missions.
The Apollo Command Module reentered with the center of mass offset from the center line; this caused the capsule to assume an angled attitude through the air, providing a sideways lift to be used for directional control. Rotational thrusters were used to steer the capsule under either automatic or manual control by changing the lift vector.
The Apollo Command Module had a set of twelve hypergolic thrusters for attitude control, and directional reentry control similar to Gemini. The Apollo Service Module and Lunar Module each had a set of sixteen R-4D hypergolic thrusters, grouped into external clusters of four, to provide both translation and attitude control. The clusters were ...
