Due to a power supply anomaly in the ground segment of the Ariane 5 launch complex, the final chronology for Flight VA250 was stopped at 20 minutes prior to liftoff (H0-20), leading to a launch postponement.

The Ariane 5 stages have been emptied of their propellant. The launcher and its two satellite passengers – TIBA-1 and Inmarsat GX5 – remain in a safe mode at the Spaceport.

The ongoing investigation has led to a new targeted launch date of Sunday, November 24, 2019 at the earliest.
