Live coverage: Two satellites lift off aboard Ariane 5

An Ariane 5 rocket ignited its hydrogen-fueled Vulcain 2 main engine and two solid rocket boosters to send two Intelsat communications satellite into orbit this week, casting a brilliant glow across its launch base carved from the jungle of French Guiana.

Watch a replay of the liftoff of an Ariane 5 rocket Wednesday from the Guiana Space Center, a spaceport carved from the edge of the Amazon rainforest. The launcher carried four Galileo navigation satellites into orbit.

NASA officials said Thursday the launch of the James Webb Space Telescope will be delayed seven months to Oct. 31, 2021, a schedule slip that takes into account work slowdowns caused by the coronavirus pandemic and the amount of testing required on the observatory before its shipment to French Guiana for liftoff on a European Ariane 5 rocket.
