Spacecraft reaction control systems are used for: attitude control during different stages of a mission; [3] station keeping in orbit; close maneuvering during docking procedures; control of orientation, or "pointing the nose" of the craft; a backup means of deorbiting; ullage motors to prime the fuel system for a main engine burn.
However, after Baldwin's lawyers argued that he was incorrectly being charged under a version of the law that was not passed until months after the shooting, the prosecutors downgraded the charges. Thereafter, Baldwin and Gutierrez-Reed faced a maximum of 18 months in prison if found guilty. [91] On February 23, Baldwin pleaded not guilty. [92]

The R-4D is a small hypergolic rocket engine, originally designed by Marquardt Corporation for use as a reaction control system thruster on vehicles of the Apollo crewed Moon landing program. Aerojet Rocketdyne manufactures and markets modern versions of the R-4D. [1]
In practice, if A and B interconvert with overall rate constants k f and k r, then for most practical purposes, the change in composition becomes negligible after t ~ 3.5/(k f + k r), or approximately five half-lives, and the system product ratio can be regarded as the result of thermodynamic control. In general, short reaction times favour ...
"A reaction control system (RCS) is a subsystem of a spacecraft whose purpose is attitude control and steering by the use of thrusters". Attitude and Orbit control "An RCS system is capable of providing small amounts of thrust in any desired direction or combination of directions".
The system was also used to push the spacecraft away from the spent second stage of the Titan II launch vehicle on first reaching orbit. The eight rotational control engines were mounted off the spacecraft's center of mass around the aft section of the Equipment Module, pointed at 90 degree positions up, down, left and right.
