Titan 4B launch timeline
SPACEFLIGHT NOW
Posted: February 13, 2004

T+0:00:00 Liftoff
The twin Solid Rocket Motor Upgrade (SRMU) boosters are ignited and the Titan 4B rocket launches from Complex 40 at Cape Canaveral Air Force Station, Florida.
T+0:00:06 Roll Program
Rocket beings a roll maneuver to the flight azimuth of 93 degrees for the travel downrange from launch site.
T+0:02:12 Stage 1 Ignition
The Titan 4B rocket's core vehicle stage 1 engine -- the Aerojet LR87-AJ-11 -- is ignited. The liquid-propellant powerplant burns Aerozine-50 fuel and nitrogen tetroxide oxidizer.
T+0:02:27 SRMU Separation
Having consumed all their solid-propellant, the two Alliant Techsystems-built solid rocket boosters are jettisoned to fall into the Atlantic Ocean.
T+0:03:20 Jettison Payload Fairing
The 56-foot long payload fairing buit by Boeing that protected the DSP-22 satellite during atmospheric ascent is separated once it is no longer needed.
T+0:05:24 Staging of Titan Core
The first stage engine shuts down and the second stage Aerojet LR91-AJ-11 engine is ignited. The spent first stage is jettisoned from the rest of the space-bound Titan 4B rocket one second after the second stage is started.
T+0:08:58 Stage 2 Shutdown
The liquid-fueled second stage engine completes its firing and the rocket enters a brief coast period before deployment of the upper stage and DSP payload.
T+0:09:01 Stage 2/IUS Separation
The Boeing-built Inertial Upper Stage is released from the Titan rocket's core vehicle, which has completed its role in the launch. The IUS and attached DSP satellite now begin a coast period through space before the first of two firings of the upper stage kick motor.
T+1:13:30 IUS SRM 1 Burn
The first stage of the solid-fueled IUS is ignited to begin the journey from low-Earth orbit to geostationary altitude for the DSP-22 satellite.
T+6:29:44 IUS Stage 1 Separation
Following a five-hour coast, the spent first stage of the IUS is jettisoned.
T+6:32:56 IUS SRM 2 Burn
The second stage of the solid-fueled IUS is ignited to complete the powered phase of the launch to place DSP-22 into orbit.
T+6:54:51 Spacecraft Separation
The Defense Support Program-22 early-warning satellite is released into space from the Inertial Upper Stage to complete the B-39 launch.
