Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A roll program or tilt maneuver is an aerodynamic maneuver that alters the attitude of a vertically-launched space launch vehicle. The maneuver is used to place the spacecraft on a proper heading toward its intended orbit.A roll program is completed shortly after the vehicle clears the tower. In the case of a crewed mission, a crew member (usually the commander) reports the roll to mission control which is then acknowledged by the capsule communicator.During the launch of a space shuttle, the roll program is simultaneously accompanied by a pitch maneuver and yaw maneuver.
