Roll program

(重定向自Pitch program)
Space Shuttle Atlantis performs the roll maneuver shortly after launching from Kennedy Space Center on STS-129.

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.
