Four satellites tucked inside the tip of a Soyuz rocket lifted off Thursday, heading for a 5,000-mile-high orbit to expand the reach of O3b’s broadband communications network. Liftoff from the European-run spaceport in French Guiana occurred at 1:37 p.m. EST (1837 GMT).

A Falcon 9 rocket carrying the heaviest payload ever launched by SpaceX took off Monday morning from Cape Canaveral with 60 satellites for then company’s Starlink broadband network.
