The Falcon 9's second stage engine has shut down after injecting the Inmarsat 5 F4 satellite into a preliminary parking orbit. The Merlin vacuum engine is due to restart at T+plus 26 minutes, 59 seconds, to put the Inmarsat 5 F4 spacecraft into a geostationary transfer orbit.

А они, случаем, не сняли камеры с первой? Для облегчения...

Вряд ли такое покажут. По трансляции были слышны возгласы - возможно народ видел разрушение ступени в прямом эфире

да я об этом же. Полюбому видели.

Second stage ignition. The Merlin vacuum engine is firing for the second time this evening to place Inmarsat 5 F4 into a high-altitude supersynchronous transfer orbit.

Chilldown of the Merlin vacuum engine is underway.

05/16/2017 02:47
The Falcon 9's second stage engine is expected to ignite at T+plus 26 minutes, 59 seconds, and burn for around 56 seconds. The engine is programmed to burn until the upper stage tanks have little propellant left in them, a tank-draining technique called "minimum residual shutdown."
Such a maneuver is intended to give the Inmarsat 5 F4 satellite the biggest boost possible into a high-altitude supersynchronous transfer orbit.
