Impulse Space, founded by SpaceX engine guru Tom Mueller, develops highly maneuverable spacecraft and propulsion systems for in-space mobility. Its product portfolio includes Mira, a maneuverable platform that has flown at least three missions, and Helios, a vehicle designed to move satellites rapidly to higher orbits. The company is targeting U.S. Space Force customers and is preparing another Mira launch expected before the end of the year after a prior flight encountered a navigation-related propellant issue. Impulse recently opened an office in Colorado as it expands its engineering team and plans to hire up to 200 new employees with proceeds from its Series D. The company’s software teams use AI coding tools, though leadership has expressed skepticism about applying current deep learning models to hardware design.
