Live coverage: Ariane 5 lifts off with two U.S.-built satellites

SpaceX’s next Falcon Heavy mission, set for April 18 from NASA’s Kennedy Space Center in Florida, will launch a powerhouse bus-sized broadband satellite for Viasat into a high-altitude circular geostationary orbit, a demanding flight profile that will require disposal of all three of the rocket’s reusable boosters.

A Boeing-built satellite on the way to join Inmarsat’s globe-spanning network geared to beam Internet and data transmission capacity to airline passengers, maritime crews and military personnel flew into orbit Monday from NASA’s Kennedy Space Center in Florida aboard an expendable Falcon 9 rocket.

After a two-day delay caused by unfavorable high-altitude winds, an Ariane 5 rocket lifted off Saturday at 3:40 p.m. EST (2040 GMT) from French Guiana with communications satellites for DirecTV and India.
