RCS (Reaction Control System)

A Reaction Control System (RCS) is an essential technology used in spacecraft to manage their orientation and movement in space. It consists of small thrusters that can quickly adjust the spacecraft's position and direction. By firing these thrusters in different combinations, the RCS helps stabilize or change the spacecraft's angle, allowing it to navigate, align instruments, or dock with other spacecraft. Essentially, the RCS enables precise maneuvering in the vacuum of space, where traditional aerodynamic controls like wings are ineffective.
