Impulse Space develops spacecraft and propulsion systems that provide transportation and mobility services for payloads operating in space. The company focuses on moving, deploying, and hosting payloads across a range of orbital destinations, including low Earth orbit, geostationary orbit, and other deep-space trajectories. Its vehicle portfolio includes Mira, a spacecraft designed for payload hosting, deployment, and orbital maneuvers, and Helios, a transfer vehicle intended to transport larger payloads between orbits. Impulse Space designs, manufactures, and tests much of its hardware in-house, covering spacecraft systems, propulsion components, and mission integration. The company supports commercial, civil, and government missions by providing in-space transportation and logistics capabilities after launch.
