The Michoud Assembly Facility (MAF) is an 832-acre (1.3 sq mi; 3.4 km2) manufacturing complex owned by NASA in New Orleans East, a district within New Orleans, Louisiana, in the United States. Organizationally it is part of NASA's Marshall Space Flight Center, and is currently a multi-tenant complex to allow commercial and government contractors, as well as government agencies, to use the site.

MAF is one of the largest manufacturing plants in the world with 43 environmentally controlled acres—174,000 m2 (1,870,000 sq ft)—under one roof, and it employs more than 4,200 people. From September 1961 to the end of the Apollo program in December 1972 the site was utilized by Chrysler Corporation to build the first stages of the Saturn I and Saturn IB, later joined by Boeing Corporation to build the first stage of the Saturn V rockets. From September 5, 1973, to September 20, 2010, the factory was used for the construction of the Space Shuttle's external fuel tanks by Martin Marietta Corporation.

In 2012, the parts of the facility dedicated to rocket construction were renamed the Chris A. Hadfield Rocket Factory (CAHRF), after the factory's former employee and Canadian astronaut Chris Hadfield.

A reaction wheel (RW) is a type of flywheel used primarily by spacecraft for three-axis attitude control, which does not require rockets or external applicators of torque. They provide a high pointing accuracy,: 362 and are particularly useful when the spacecraft must be rotated by very small amounts, such as keeping a telescope pointed at a star.

A reaction wheel is sometimes operated as (and referred to as) a momentum wheel, by operating it at a constant (or near-constant) rotation speed, in order to imbue a satellite with a large amount of stored angular momentum. Doing so alters the spacecraft's rotational dynamics so that disturbance torques perpendicular to one axis of the satellite (the axis parallel to the wheel's spin axis) do not result directly in spacecraft angular motion about the same axis as the disturbance torque; instead, they result in (generally smaller) angular motion (precession) of that spacecraft axis about a perpendicular axis. This has the effect of tending to stabilize that spacecraft axis to point in a nearly-fixed direction,: 362 allowing for a less-complicated attitude control system. Satellites using this "momentum-bias" stabilization approach include SCISAT-1; by orienting the momentum wheel's axis to be parallel to the orbit-normal vector, this satellite is in a "pitch momentum bias" configuration.

A control moment gyroscope (CMG) is a related but different type of attitude actuator, generally consisting of a momentum wheel mounted in a one-axis or two-axis gimbal.: 362 When mounted to a rigid spacecraft, applying a constant torque to the wheel using one of the gimbal motors causes the spacecraft to develop a constant angular velocity about a perpendicular axis, thus allowing control of the spacecraft's pointing direction. CMGs are generally able to produce larger sustained torques than RWs with less motor heating, and are preferentially used in larger and/or more-agile spacecraft, including Skylab, Mir, and the International Space Station.

In a supply chain, a vendor, or a seller, is an enterprise that contributes goods or services. Generally, a supply chain vendor manufactures inventory/stock items and sells them to the next link in the chain. Today, these terms refer to a supplier of any goods or service.
