Posted: September 30, 2009T-00:00LiftoffThe Delta 2 rocket's main engine and twin vernier steering thrusters are started moments before launch. Six of the nine strap-on solid rocket motors are ignited at T-0 to begin the mission.T+01:04.0Ground SRB BurnoutThe six ground-start Alliant TechSystems-built solid rocket motors consume all their propellant and burn out.T+01:05.5Air-Lit SRM IgnitionThe three remaining solid rocket motors strapped to the Delta 2 rocket's first stage are ignited.T+01:26.0Jettison SRBsThe spent solid rocket boosters are jettisoned to fall into the Pacific Ocean. The spent casings remained attached until the vehicle passed into preset drop zone, clear of offshore oil platforms.T+01:30.0Begin Dog-legAfter initially flying from Vandenberg along a 196-degree flight azimuth, the rocket begins steering itself to obtain the desired orbital inclination. This dog-leg maneuver continues for 52 seconds.T+02:11.5Jettison Air-Lit SRMsHaving burned out, the three spent air-started solid rocket boosters are jettisoned toward the Pacific Ocean.T+04:23.4Main Engine CutoffAfter consuming its RP-1 fuel and liquid oxygen, the Pratt & Whitney Rocketdyne RS-27A first stage main engine is shut down. The vernier engines cut off moments later.T+04:31.4Stage SeparationThe Delta rocket's first stage is separated now, having completed its job. The spent stage will fall into the Pacific Ocean.T+04:36.9Second Stage IgnitionWith the stage jettisoned, the rocket's second stage takes over. The Aerojet AJ118-K liquid-fueled engine ignites for the first of two firings needed to place the WorldView 2 spacecraft into the proper orbit.T+04:41.0Jettison Payload FairingThe 10-foot diameter payload fairing that protected the WorldView 2 cargo atop the Delta 2 during the atmospheric ascent is jettisoned is two halves.T+10:52.4Second Stage Cutoff 1The second stage engine shuts down to complete its first firing of the launch. The rocket and attached spacecraft are now in a long coast period before the second stage reignites. The orbit achieved should be 435 nautical miles at apogee, 106 miles at perigee and inclined 98.6 degrees.T+53:34.0Second Stage RestartDelta's second stage engine reignites for a short firing to boost the elliptical orbit into a more circular one.T+53:56.4Second Stage Cutoff 2The second stage shuts down after a 22-second burn. The orbit achieved should be 419 nautical miles at apogee, 413 miles at perigee and inclined 98.6 degrees.T+60:30.0Initiate SpinThe second stage begins a nine-degree per second spin in preparation for releasing the WorldView 2 spacecraft to fly on its own.T+61:40.0Payload SeparationThe WorldView 2 commercial Earth-imaging satellite is released from the Delta 2 rocket, completing the launch.Data source: ULA.STS-134 PatchFree shipping to U.S. addresses!The final planned flight of space shuttle Endeavour is symbolized in the official embroidered crew patch for STS-134.
