Titan G-9 Ascent Timeline
SPACEFLIGHT NOW
Posted: January 19, 2001

T-00:00.0 Stage 1 ignition
The first stage LR87 liquid propellant engine ignites and comes up to proper thrust.
T+00:03.2 Liftoff
The Titan 2 rocket begins its journey to orbit with the DMSP F16 weather satellite from Space Launch Complex-4 West at Vandenberg Air Force Base, California.
T+02:30.2 Stage 1 shutdown
The first stage engine shuts down via command by the rocket's guidance system based upon computer logic.
T+02:30.5 Start stage 2
The LR91 liquid propellant second stage engine is ignited and the first stage is separated as the Titan 2 rocket continues its ascent. The first stage falls into the Pacific Ocean.
T+03:35.0 Jettison fairing
The payload fairing that protected the DMSP F16 spacecraft during atmospheric ascent is separated once heating conditions are acceptable.
T+05:26.6 Stage 2 shutdown
The Titan 2 rocket's second stage shuts down by guidance command, completed the powered phase of flight for the former Intercontinental Ballistic Missile. The stage is then prepared to release the DMSP satellite.
T+06:30.0 Payload separation
The U.S. Air Force's Defense Meteorological Satellite Program F16 spacecraft is deployed from the Titan 2 rocket's second stage.
T+13:58 Kick motor ignition
The apogee kick motor attached to the bottom of DMSP F16 is ignited to inject the satellite into a stable orbit around Earth.
T+14:49 Kick motor burnout
The kick motor completes its firing and will remain attached to the satellite. Following a 60-second firing of the spacecraft's hydrazine thrusters at T+plus 17 minutes, 23 seconds, the DMSP spacecraft should achieve a near-circular orbit around Earth's poles at an altitude of around 458 nautical miles and inclined 98.7 degrees to the equator.
