The launch of a French rocket Ariane 5 into orbit was delayed by striking workers.
The transfer of the rocket to its launch pad was postponed after striking workers erected a barricade of tyres and wooden pallets at the Kourou Space Center, which is in French Guiana, on the northeastern coast of South America.
Due to a strike, the scheduled transfer operation to move the rocket from the final assembly building to the launching zone could not go ahead
"Due to a strike, the scheduled transfer operation to move the rocket from the final assembly building to the launching zone could not go ahead," Arianespace said in a statement.
The VA236 rocket is set to put into orbit two communications satellites. One satellite, called SGDC, will provide strategic communications for the Brazilian government and military services, and beam broadband services across all of the country's territory, helping to provide internet access to remote and underserved communities.
The other, KOREASAT-7, owned by South Korea's KTsat, will provide a range of video and data services over Korea, the Philippines, Southeast Asia, India and Indonesia.
