Elon Musk’s SpaceX has banked another $100 million in corporate funding.
The Hawthorne, Calif.-based rocket company disclosed the recent equity financing in a Nov. 27 regulatory filing. That brings its latest funding round to a total $450 million, including investments disclosed in a regulatory filing earlier this year.
The privately held company declined to disclose its revenue, but published reports put the current valuation of SpaceX at roughly $21.5 billion. SpaceX holds launch-services contracts with NASA, the U.S. Air Force and sundry commercial clients.
Musk’s repeated pronouncements on long-range plans for a Mars mission have gained prominent public attention, but most of its revenue comes from customers paying to have satellites lifted into space aboard the company’s reusable Falcon 9 rockets. It also shuttles cargo to the International Space Station and is set to begin astronaut shuttles to the orbiting space lab in the future.
