Live coverage: Two satellites lift off aboard Ariane 5

Follow the key events of the Soyuz rocket’s ascent into orbit from the Guiana Space Center with two satellites for Europe’s Galileo navigation system.

A Russian-built Soyuz booster lifted off Friday from the European-run spaceport in French Guiana, carrying four new broadband Internet satellites to orbit to join the O3b network owned by SES. Launch occurred at 1710:06 GMT (12:10:06 p.m. EST).

Ground crews in French Guiana on Monday transferred an Ariane 5 rocket to its launch pad, moving the vehicle into position for liftoff Wednesday with four European Galileo navigation satellites on the Ariane 5’s last flight with an older-generation, out-of-production upper stage.
