Live coverage: Soyuz blasts off on third mission for O3b

An Ariane 5 rocket will make its fourth flight of the year Wednesday, hauling two communications satellites into orbit for Inmarsat, Hellas-Sat and India’s space agency.

Something went wrong with a Russian Progress cargo spacecraft moments before it deployed into orbit Tuesday on the way to the International Space Station, and investigators are analyzing whether the stricken supply ship may have lost control after a botched separation from its Soyuz rocket booster.

Launch crews rolled out a nearly 180-foot-tall Ariane 5 rocket to its launch pad Monday in a final major step before liftoff with the Arabsat 6B and GSAT 15 communications satellites to broadcast television, broadband and other telecom services across Africa, the Middle East, Central Asia and India.
