Retrorockets

Retrorockets are small rocket engines used to slow down or stop the motion of a spacecraft. They are typically used during the descent phase of a mission, such as landing on a planet or returning to Earth. Retrorockets work by expelling a high-velocity stream of gas in the opposite direction of the spacecraft's motion, creating a force that slows it down. They are often used in combination with other types of rockets, such as attitude control thrusters, to precisely control the spacecraft's motion. Retrorockets are critical for ensuring a safe and controlled landing or reentry, and have been used in many historic space missions, including the Apollo moon landings and the Space Shuttle program.
