Elon Musk's SpaceX, fresh off the successful launch this month of the world's most powerful rocket, won an endorsement on Wednesday from the top U.S. communications regulator to build a broadband network using satellites.

Federal Communications Commission Chairman Ajit Pai proposed the approval of an application by SpaceX to provide broadband services using satellites in the United States and worldwide.

"Satellite technology can help reach Americans who live in rural or hard-to-serve places where fiber optic cables and cell towers do not reach," Pai said in a statement.
