Live coverage: Two satellites lift off aboard Ariane 5

The launch will be managed by Arianespace and will carry the third satellite for the Optical Space Component (CSO– Composante Spatiale Optique) program. Liftoff is scheduled for Thursday, March 6, at 1:24 p.m. Kourou time (11:24 a.m. EST, 1624 UTC).

SpaceX launched the next group of satellites for the company’s Starlink broadband network Wednesday at 9:25 p.m. EDT (0125 GMT Thursday) from pad 40 at Cape Canaveral Air Force Station. The satellites rode into orbit on a Falcon 9 rocket with a first stage flown on four previous missions, and the booster made a successful fifth landing on a SpaceX drone ship in the Atlantic Ocean.

Arianespace will fit in a bonus launch of a Soyuz rocket from French Guiana in May to deliver two more European Galileo navigation satellites to orbit, giving the French launch services firm 12 missions on its 2016 manifest, officials said Thursday.
