Impulse Space just got a lot more money to help finance its big ambitions in the final frontier.
The California-based company — which was founded in 2021 by propulsion expert Tom Mueller, the first person Elon Musk ever hired at SpaceX — announced today (June 2) that it has raised $500 million in a "Series D" investment round. It will use the funds to scale up the production and deployment of its ultra-mobile spacecraft, which Impulse Space thinks will help transform the off-Earth economy.
