Why Do Rockets Perform A Rolling Motion After Launch?

"Launching rockets into space is no easy task. Engineers and scientists need to ensure the vessels have enough thrust and fuel to escape Earth's gravity. To achieve this feat, rockets launch at curved trajectories to take advantage of the Earth's gravitational pull. Rolling is another trick rockets use to stay on course.

A rolling motion, alternatively known as a roll program, stems from the rotational movements all flying vessels, including rockets and airplanes, use to navigate. Every movement involves curving one of three axes, and these movements are known as the roll, yaw, and pitch. In airplane terms, a roll occurs when the lift in one wing is higher than the other and makes the plane, well, roll. The rear horizontal tail rudder controls the pitch and uses it to adjust elevation. Meanwhile, the vertical rudder controls the yaw, turning the...
