Employees work at the mission control centre before the launch of the Soyuz-ST-A carrier rocket with a block of commercial space satellites at the Guiana Space Centre in Kourou, Guiana, France. The launch of Russia's Soyuz-ST carrier rocket with five European satellites on board from Kourou spaceport in French Guiana was delayed from December 17 to December 18 due to a detected control system error, the Russian State Space Corporation Roscosmos said.
