The launch of an ILS Proton launch vehicle with the ASTRA 2G satellite was postponed today due to the off-nominal operation of the Breeze M upper stage gyro unit during planned pre-flight testing.
The additional time is needed due to the required destacking and replacement of the affected gyro unit and to ensure complete flight readiness of the vehicle. The satellite is being launched for SES of Luxembourg and was built by Airbus Defence and Space.
The vehicle and satellite remain in a safe configuration at the launch site.
