Live coverage: Ariane 5 blasts off with two Intelsat satellites

SpaceX fired up a Falcon 9 rocket at Cape Canaveral Wednesday in a pre-flight test for a Starlink satellite launch Sunday, moving closer to the company’s final mission before sending two NASA astronauts into orbit for the first time May 27.

Redesigned titanium steering fins will fly aboard a Falcon 9 rocket launching Sunday from California, part of upgrades SpaceX says will ease the reuse of future boosters.

Two geostationary communications satellites rode an Ariane 5 rocket into orbit Wednesday from a launch pad in French Guiana, embarking on missions to broadcast television across Europe, the Middle East and Africa, link European air travelers with Wi-Fi, and relay video and data signals across India.
