Orbit Attitude and Maneuvering System

The OAMS had 16 small, fixed-position, fixed-thrust rocket engines which burned hypergolic propellants (monomethylhydrazine fuel using nitrogen tetroxide as oxidizer) fed under pressure from a pair of tanks located in the aft Equipment Module.

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.

Project Mercury astronauts could only adjust yaw, pitch, or roll, but Gemini crewmen had full manual control over their flight path.

I did a fly-around inspection of Gemini 7, literally flying rings around it, and I could move to within inches of it in perfect confidence".
