Elon Musk's Spacex wants to deliver high-speed internet to the world using thousands of small satellites -- and this week that plan is moving closer to reality.

The company is slated to Launch a rocket from Vandenberg Air Force Base in California at 6:17 a.m. local time on Wednesday.

On board will be two experimental satellites that will test out the technology SpaceX plans to use for its internet service, according to public filings.

SpaceX's plan is to "deliver broadband services directly to [people] anywhere in the United States or around the world" at speeds similar to some of the quickest ground-based internet connections.

FCC chairman Pai, who was appointed by President Trump, said last week that if SpaceX gets approval for its satellite project, it'll be a first for an American-based company in the internet-in-space race.

Some of SpaceX's internal financial documents obtained by the Wall Street Journal last year show the company has high expectations for this satellite network.

According to European firm Airbus , which was the primary contractor for PAZ, the satellite will serve "many different applications," including defense and security.
