Reaction control systems

Reaction control systems (RCS) are small thrusters used on spacecraft to control orientation (rotation) and position in space. They work by expelling propellant in specific directions, creating a force that gently spins, tilts, or moves the spacecraft as needed. Think of them as tiny steering engines that help spacecraft navigate and stay steady without relying on aerodynamic surfaces like wings, which don't work in space. RCS are essential for tasks like docking, adjusting orbits, and maintaining stability during space missions.
