NOAA-L Ascent Timeline
SPACEFLIGHT NOW
Posted: September 19, 2000

T-00:03.2 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 NOAA-L weather satellite from Space Launch Complex-4 West at Vandenberg Air Force Base, California.
T+02:30 Stage 1 shutdown
The first stage engine shuts down via command by the rocket's guidance system based upon computer logic.
T+02:31 Stage separation, 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+03:44 Jettison payload fairing
The payload fairing that protected the NOAA-L spacecraft during atmospheric ascent is separated once heating conditions are acceptable.
T+05:26 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 NOAA-L satellite.
T+06:31 NOAA-L separation
The National Oceanic and Atmospheric Administration's NOAA-L weather satellite is deployed from the Titan 2 rocket's second stage.
T+15:04 Kick motor ignition
The Thiokol Star 37XFP solid-fuel apogee kick motor attached to the bottom of NOAA-L is ignited inject the satellite into a stable orbit around Earth.
T+15:55 Kick motor burnout
The NOAA-L spacecraft should achieve a circular orbit around Earth's poles at an altitude of around 470 miles and inclined 98.7 degrees to the equator. The kick motor will remain attached to the satellite.
