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-085, lifts off and begins a vertical rise away from Space Launch Complex 41 at Cape Canaveral Air Force Station, Fla.
T+00:17.3 Begin Pitch/Roll/Yaw Maneuver
The 188-foot-tall Atlas 5 begins to maneuver itself on the proper trajectory east of Complex 41 on an azimuth of 94 degrees.
T+01:30.9 Max-Q
The Atlas 5 rocket passes the region of flight known as maximum dynamic pressure, or Max-Q.
T+0:04:02 Main Engine Cutoff
The RD-180 main engine completes its firing after consuming its kerosene and liquid oxygen fuel supply in the Atlas first stage.
T+0:04:08 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+0:04:18 Centaur Ignition 1
The Centaur RL10 engine ignites for the longer of the two upper stage firings. This burn will inject the Centaur stage and MAVEN spacecraft into a parking orbit.
T+0:04:26 Nose Cone Jettison
The payload fairing that protected the MAVEN spacecraft during the climb through the atmosphere is no longer needed and is separated.
T+0:13:48 Centaur Cutoff 1
The Centaur engine shuts down after arriving in a planned parking orbit. The vehicle enters a lengthy coast period lasting nearly 28 minutes before arriving at the required location in space for the second burn.
T+0:41:24 Centaur Ignition 2
The Centaur re-ignites to propel the payload into the desired Earth escape trajectory from the parking achieved earlier in the launch sequence.
T+0:46:53 Centaur Cutoff 2
At the conclusion of its second firing, the Centaur will have delivered the MAVEN spacecraft on a hyperbolic escape trajectory toward Mars.
T+0:52:42 Spacecraft Separation
NASA's Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft is released from the Centaur upper stage to complete the AV-038 launch.
