According to Tech Funding News, Impulse Space, a space infrastructure company founded by SpaceX's first employee Tom Mueller, has completed a $500 million Series D funding round, led jointly by 137 Ventures and BANNER VC, with a post-money valuation of $4.26 billion.
So far, Impulse Space has raised over $1 billion in total funding. Founded in 2021, Impulse Space primarily addresses the maneuvering issues of spacecraft after launch into orbit. The company builds chemical propulsion spacecraft for rapid trajectory changes, orbital transfers, and in-orbit maneuvers. Its Mira precision maneuvering vehicle has completed multiple missions, and the Helios high-energy upper stage is scheduled for its first flight in 2027, aiming to quickly deliver payloads to GEO, the Moon, and heliocentric orbits.
Tom Mueller, who was SpaceX's first employee, led the development of the Merlin engine used in Falcon 9 and the Raptor engine used in Starship. He stated that Impulse Space is not just building spacecraft but is constructing the economic and technological engine that drives humanity into space.
