Arianespace’s Soyuz ST-B rocket is set to launch the first satellites that will act as pathfinders to a huge satellite constellation for OneWeb that is aimed at providing full global internet coverage. The launch is set to take place in a window that opens at 21:37 UTC at the European Spaceport in French Guiana.
The upcoming Flight VS21 will mark the 21st liftoff of Soyuz from French Guiana since this medium-lift launcher’s 2011 operational debut at the Spaceport.
The rocket has suffered delays in the path to this launch, first with the discovery of a pinhole in the Fregat upper stage that has since been repaired. Then, a small slip occurred as Russian officials checked for commonality with the problem suffered by a Soyuz 2-1b launch of EgyptSat-A that successfully deployed the satellite but had problems during third stage flight.
