T-0:00:02.7	Engine Start
The Russian-designed RD-180 main engine is ignited and undergoes checkout prior to launch.
T+0:00:01.1	Liftoff
The Atlas 5 vehicle, designated AV-013, lifts off and begins a vertical rise away from Complex 41 at Cape Canaveral Air Force Station, Florida.
T+0:04:04.4	Main Engine Cutoff
The RD-180 main engine completes its firing after consuming the kerosene and liquid oxygen fuel supply in the Atlas first stage.
T+0:04:10.4	Stage Separation
The Common Core Booster first stage of the Atlas 5 rocket separates from the Centaur upper stage. Over the next few seconds, the Centaur engine liquid hydrogen and liquid oxygen systems are readied for ignition.
T+0:04:20.4	Centaur Ignition 1
The Centaur RL10 engine ignites for the longest of the night's three upper stage firings. This burn will inject the Centaur stage and spacecraft into the mission's initial Earth orbit.
T+0:04:28.4	Nose Cone Jettison
The payload fairing that protected the spacecraft during launch is separated once heating levels drop to predetermined limits.
T+0:14:23.2	Centaur Cutoff 1
The Centaur engine shuts down after arriving in the planned 306-mile circular orbit inclined 46 degrees to the equator.
T+0:18:02.2	Orbital Express Release
The Orbital Express in-space refueling demonstration mission payload consisting of the combined ASTRO and NextSat spacecraft separates from atop the rocket.
T+0:22:17.2	MidSTAR 1 Release
The U.S. Naval Academy's Midshipman Space Technology Applications Research Satellite (MidSTAR 1) is separated from the payload adapter ring on the rocket.
T+0:33:07.0	Centaur Ignition 2
The Centaur re-ignites for a two-step process to reach an entirely different orbit for deploying the other three satellite payloads.
T+0:34:29.2	Centaur Cutoff 2
At the conclusion of its second firing, the Centaur will have entered a so-called "fast transfer orbit" sequence to travel from the initial satellite deployment orbit to the orbit for release of the second batch of payloads. The intermediate orbit will have a low point of 247 miles, a high point of 2,135 miles and inclination of 44 degrees.
T+0:46:27.1	Centaur Ignition 3
After briefly coasting in the highly elliptical fast transfer orbit, Centaur ignites again to reach the desired orbit for release of the three remaining satellites.
T+0:48:19.1	Centaur Cutoff 3
The upper stage rocket motor completes its third burn -- the most ever for an Atlas 5 mission -- to enter a circular orbit 348 miles high with an inclination of 35.4 degrees.
T+0:56:07.1	STPSat 1 Release
The Space Test Program's STPSat 1 spacecraft is deployed from the payload adapter ring on the rocket.
T+1:01:40.1	CFESat Release
The Los Alamos National Laboratory's CFESat is deployed from the payload adapter ring on the rocket.
T+1:05:38.1	FalconSat 3 Release
The U.S. Air Force Academy's FalconSat 3 is deployed from the payload adapter ring on the rocket, completing this Atlas 5 rocket launch.
