Updated | Elon Musk wants to create a constellation of thousands of satellites to beam internet down to Earth.

Today, he got one step closer to that goal as SpaceX launched two prototype Starlink satellites.

Due to launch yesterday, the lift-off on a Falcon 9 rocket was delayed by strong upper winds. Instead, the rocket launched from Vandenberg Air Base Thursday morning at 9.17 a.m. ET.

Musk confirmed on Twitter the two Starlink satellites "Tintin A & B" were deployed and communicating with Earth stations.

Starlink could one day beam high-speed internet worldwide using an orbiting network of satellites. The plan has been in the public eye since at least 2014, when Musk tweeted: "SpaceX is still in the early stages of developing advanced micro-satellites operating in large formations."

He confirmed the purpose of these satellites in Twitter comments, saying the company's internet would be "unfettered certainly and at a very low cost."

Just yesterday, Musk wrote the Starlink system will serve the "least served." This name, he added, was inspired by John Green's novel, The Fault in Our Stars.

According to a Business Insider analysis of a SpaceX Federal Communications Commission filing, the first 800 satellites deployed could provide broadband coverage worldwide.

With thousands more satellites planned, Starlink will eventually increase bandwidth capacity and availability around the equator and at the North and South Pole.

SpaceX has received support from Federal Communications Commission chairman Ajit Pai. He recently stated: "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."

The Starlink prototypes piggy-backed on the launch of PAZ, a Spanish radar-imaging satellite.

This was the second outing for the Falcon 9's first stage, which launched the Earth observation satellite FORMOSAT-5 for Taiwan's National Space Organization last August.

It's not all good news for SpaceX, however. Shortly before the PAZ launch, Musk tweeted the company would try to catch the rocket's nosecone. But this payload fairing missed the landing by several hundred feet and landed in the ocean.

This article has been updated to reflect the success of the Paz launch.
