Editing Thrust vectoring (section)

====Vernier thrusters====
An effect similar to thrust vectoring can be produced with multiple [[vernier thruster]]s, small auxiliary combustion chambers which lack their own turbopumps and can gimbal on one axis. These were used on the [[Atlas missile|Atlas]] and [[R-7 (rocket family)|R-7]] missiles and are still used on the [[Soyuz rocket]], which is descended from the R-7, but are seldom used on new designs due to their complexity and weight. These are distinct from [[reaction control system]] thrusters, which are fixed and independent rocket engines used for maneuvering in space.
