Update for 8:47 pm ET: Arianespace representatives have reported that the SES-14 and Al Yah 3 satellites are in their expected orbits after the company lost contact with its Ariane 5 rocket’s upper stage during tonight’s launch. Here’s the latest statement from Arianespace:
“The launcher’s liftoff took place on January 25, 2018 at 7:20 pm. A few seconds after ignition of the upper stage, the second tracking station located in Natal, Brazil, did not acquire the launcher telemetry. This lack of telemetry lasted throughout the rest of powered flight. Subsequently, both satellites were confirmed separated, acquired and they are on orbit. SES-14 and Al Yah 3 are communicating with their respective control centers. Both missions are continuing.”
