87-й запуск ракеты Ariane-5, 13 лет запусков без аварий (безаварийная серия с 2003 года).
01:30 Plus+14 minutes. This upper stage engine is about 5 minutes into a planned 16-minute burn. Ariane 5 is at an altitude of 140 kilometers. A tracking station on Ascension Island in the Atlantic Ocean has picked up signals from the Ariane 5.
01:28 The Ariane 5 has passed over the horizon from Kourou and is now out of range of the Galliot tracking station near the launch pad.
01:25 Plus+9 minutes, 15 seconds. The main cryogenic stage's Vulcain engine has cut off and the spent stage has separated. It will fall back into the atmosphere into the Atlantic Ocean off the west coast of Africa. And the upper stage's HM7B engine is now firing to inject the Intelsat 33e and Intelsat 36 satellites into orbit.
01:23 Plus+8 minutes. Now in range of a communications station in Natal, Brazil, the launcher is about to shut down its first stage and ignite its cryogenic upper stage. Downrange distance is now about 1,200 km, altitude is 162 km and velocity is 5.61 km/s.
01:21 Plus+5 minutes, 15 seconds. Altitude is 156 km, downrange distance is 513 km and velocity is 3.21 km/s.
01:20 Ariane 5 climbs towards orbit
01:19 Plus+3 minutes, 30 seconds. Separation of the rocket's nose cone has been confirmed. The Ariane 5 core stage will continue burning until about Plus+9 minutes into the mission.
01:18 Plus+2 minutes, 30 seconds The solid rocket boosters have been jettisoned from the Ariane 5 rocket's core stage after consuming approximately 480 metric tons of propellant. The liquid-fueled Vulcain 2 main engine continues to fire to propel the vehicle and its satellite payload to space.
01:17 Plus+60 seconds The vehicle is on the proper heading as it rides the power of the twin solid rocket boosters and main stage liquid-fueled engine.
01:16 Liftoff! Liftoff of an Ariane 5 rocket on a dedicated dual-satellite delivery mission for Intelsat.
