Posted: October 10, 2003

T-00:03 Stage 1 ignition
The first stage LR87 liquid propellant engine ignites and comes up to proper thrust.
T+00:00 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+02:29 Stage 1 shutdown
After consuming its supply of hypergolic propellants, the first stage engine shuts down.
T+02:30 Stage 2 ignition
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 Jettison fairing
The payload fairing that protected the DMSP F16 spacecraft during atmospheric ascent is separated once heating conditions are acceptable.
T+05:25 Stage 2 shutdown
The Titan 2 rocket's second stage shuts down, completing the powered phase of flight for the former Intercontinental Ballistic Missile. The stage then prepares to release the DMSP satellite.
T+06:29 Payload separation
The U.S. Air Force's Defense Meteorological Satellite Program F16 spacecraft is deployed from the Titan 2 rocket's second stage on a sub-orbital trajectory.
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. The orbit achieved should be 421 by 460 nautical miles.
T+14:59 Orbit trim maneuver
A 21-second firing of the spacecraft's hydrazine thrusters begins to put the spacecraft into a circular orbit around Earth's poles at an altitude of 458 nautical miles and inclined 98.7 degrees to the equator.
