Reaction control system

A reaction control system (RCS) is a technology used in spacecraft to maneuver and stabilize their orientation in space. Unlike engines that propel a spacecraft forward, an RCS uses small thrusters to change its position or rotation. These thrusters can quickly push the spacecraft in different directions, allowing it to adjust its angle or trajectory. This is essential during tasks like docking with other spacecraft, maintaining a specific attitude, or performing delicate maneuvers. In essence, an RCS helps a spacecraft effectively control its movement and orientation in the vacuum of space.
