Live coverage: Two satellites lift off aboard Ariane 5

The first Soyuz launch from Kazakhstan carrying a full load of more than 30 Florida-built satellites for OneWeb’s broadband Internet network has slipped from December to mid-to-late January, OneWeb officials said.

SpaceX’s Falcon Heavy rocket lifted off from NASA’s Kennedy Space Center in Florida at 2:30 a.m. EDT (0630 GMT) to begin a three-and-a-half hour mission to deliver two dozen satellites into three distinct orbits. The Falcon Heavy’s two side boosters returned to Cape Canaveral for successful landings, but the center core stage crashed during a landing attempt on SpaceX’s drone ship in the Atlantic Ocean.

A Soyuz rocket launched Friday with four commercial satellites to expand broadband Internet coverage in remote parts of the world, climbing into orbit from the Guiana Space Center positioned on the northeastern shore of South America.
