Company Overview
Impulse Space is an American aerospace company founded in 2021 by former SpaceX founding member Tom Mueller. The company specializes in developing and providing in-space transportation services, often referred to as "last-mile" payload delivery. It designs and manufactures orbital transfer vehicles (OTVs), such as its Mira and Helios spacecraft, and associated propulsion systems. These vehicles are designed to move satellites and other payloads from a launch vehicle's drop-off point in Low Earth Orbit (LEO) to their final, often higher-energy, operational orbits, including Medium Earth Orbit (MEO), Geostationary Orbit (GEO), and beyond. The company aims to provide rapid, economical, and agile logistics for commercial, civil, and defense customers. Impulse Space has raised significant venture capital, including a $300 million Series C round, to scale production and meet customer demand.
