"The launch of the Soyuz-ST-B rocket with Galileo spacecraft, scheduled for December 3 from the Guiana Space Center, has been postponed for a day due to the unavailability of the French shipborne station for receiving telemetric information," the Roscosmos Telegram channel says.

It is noted that the launch is now scheduled for December 4 at 03:23 Moscow time.

Earlier, the launch of the Soyuz-ST-B launch vehicle was postponed due to bad weather.
