Explain the propulsion and attitude control systems used to maintain the position and orientation of the ISS.

The International Space Station (ISS) relies on propulsion and attitude control systems to maintain its position and orientation in space. These systems are crucial for ensuring the stability, maneuverability, and precise control of the ISS. Let's explore the two key components in detail: 1. Propulsion Systems: * Orbital Maneuvering System (OMS): The OMS consists of engines located on the back of the Space Shuttle or the Russian Service Module. These engines provide the primary means of propulsion for large-scale maneuvers, such as adjusting the ISS's orbit or performing reboosts to counteract atmospheric drag. * Reaction Control System (RCS): The RCS comprises smaller thrusters located at various points on the ISS, including the Zvezda Service Module, the Russian Progress spacecraft, and the U.S. mod....
