SpaceX, which raised $1.9 billion in August, didn’t immediately reply to a request for comment.

Since the previous funding round, SpaceX, already one of the world’s most valuable private companies, flew its first regular crew mission to the International Space Station for NASA. It was another milestone for a company pioneering the rush to cash in on the commercialization of space — and planning major investments in satellite-based internet service and a big new rocket.

Last week, SpaceX performed the first high-altitude test of its new Starship SN8 prototype vehicle, which is designed to carry humans to the moon, Mars and other destinations. Musk deemed the flight a success, even though the test ended with a fiery crash landing in South Texas.

SpaceX has two additional Starship test vehicles nearing completion and Musk has said the craft is likely to conduct its first orbital flight in 2021.

The Hawthorne, California-based company is also under contract with the National Aeronautics and Space Administration to build a Starship that can land humans on the moon as part of the agency’s Artemis program. Ultimately, Musk wants to send hundreds of Starships to colonize Mars and spread human life beyond Earth.

In addition to human exploration, SpaceX is building out its Starlink satellite constellation to provide worldwide broadband Internet from low-Earth orbit. The company has launched more than 700 satellites with thousands more planned to offer global coverage. The company has opened a “Better Than Nothing” beta testing program in the U.S. and Canada, with kits costing $499 plus $99 per month for the service.
