Launch |
Producing about 2.6 million pounds of thrust, the Ariane 5 rocket's two solid rocket boosters ignite to lift the launcher into the sky. |
|
H0+00:12.6 |
Start Pitch Maneuver |
The Ariane 5 rocket begins to pitch over after rising vertically from the ELA-3 launch pad. |
|
H0+00:17.1 |
Start Roll Maneuver |
The Ariane 5 rocket starts its roll maneuver to head east away from the Guiana Space Center. |
|
H0+00:48.4 |
Mach 1 |
At an altitude of 6,640 meters, or about 21,785 feet, the Ariane 5 launcher passes the speed of sound. |
|
H0+02:23 |
Booster Separation |
The solid rocket boosters exhaust their propellant and are jettisoned from the Ariane 5's first stage. At this point in the flight, Ariane 5 is traveling at about 2.01 kilometers per second, or about 4,500 mph. |
|
H0+03:21 |
Jettison Payload Fairing |
The two halves of the Ariane 5's 5.4-meter, or 17.7-foot, diameter payload fairing are jettisoned once the rocket leaves the thick lower atmosphere at an altitude of 111 kilometers, or 69 miles. |

Main Stage Shutdown |
The cryogenic first stage's Vulcain 2 main engine shuts down. |
|
H0+08:56 |
Stage Separation |
Explosive bolts fire to separate the Ariane 5's first and second stages. |
|
H0+09:00 |
Upper Stage Ignition |
The upper stage's HM7B engine, burning liquid hydrogen and liquid oxygen, ignites to propel the Intelsat 30 and Arsat 1 satellites to orbit. |
|
H0+24:40 |
Upper Stage Shutdown |
The upper stage's HM7B engine shuts down after reaching an orbit with a low point of 249.8 kilometers (155.2 miles), a high point of 35,786 kilometers (22,236 miles) and an inclination of 6 degrees. |

H0+27:52 |
Intelsat 30 Separation |
The Ariane 5 rocket deploys the Intelsat 30 communications satellite from the dual-payload composite's upper berth. |
|
H0+31:48 |
Sylda 5 Separation |
The Sylda 5 dual-payload adapter is jettisoned to expose the Arsat 1 satellite for separation. |
|
H0+33:43 |
Arsat 1 Separation |
The Ariane 5 rocket deploys the Arsat 1 communications satellite. |
