Live coverage: SpaceX launches another batch of Starlink satellites

The third Ariane 5 flight of the year is on track for a late afternoon liftoff Thursday from French Guiana with two U.S.-built communications satellites to broadcast television channels to millions of DISH Network subscribers and improve banking services across the islands of Indonesia.

Watch the launch of a commercial Falcon 9 rocket carrying a Dragon cargo ship bound for the International Space Station, as seen live on NASA Television.

An Ariane 5 rocket emerged from the final assembly building at the Guiana Space Center in South America on Monday for the journey across the tropical spaceport to the ELA-3 launch zone, where the 179-foot-tall (54.8-meter) booster will lift off Tuesday with a pair of commercial communications satellites.
