Retro Rockets
Retro rockets are a type of rocket engine that is used to slow down or stop the motion of a spacecraft. They are typically used during the descent phase of a mission, such as when a spacecraft is landing on a planet or returning to Earth. Retro rockets work by expelling a high-velocity stream of gas in the opposite direction of the spacecraft's motion, which creates a force that slows the spacecraft down. They are often used in combination with other types of rocket engines, such as main engines or attitude control thrusters, to provide precise control over the spacecraft's motion. Retro rockets have been used in many historic space missions, including the Apollo moon landings and the Space Shuttle program.
