Impulse Space vs Astranis
Side-by-side comparison of AI visibility scores, market position, and capabilities
Impulse Space raised $150M Series B in 2024 for its high-performance chemical propulsion spacecraft (Mira and Helios) that provide in-space transportation, enabling rapid satellite deployment and orbital transfer.
About
Impulse Space develops orbital transfer vehicles (OTVs) — spacecraft with high-performance chemical propulsion systems that can transport satellite payloads from launch vehicle deployment orbits to their operational orbits, or maneuver constellations for rapid response missions. The company's Mira vehicle targets LEO and MEO missions while the larger Helios vehicle aims for GEO and cislunar missions.
Astranis is building the world's smallest geostationary communication satellites, providing dedicated broadband connectivity to underserved countries and island regions. HQ: San Francisco.
About
Astranis is a satellite internet company building the world's smallest geostationary (GEO) communication satellites — roughly the size of a washing machine at ~400kg, compared to traditional telecom satellites weighing 6,000kg+. Founded in 2015 by John Gedmark and Ryan McLinko, Astranis has developed a miniaturized satellite platform that dramatically reduces the cost and lead time of deploying dedicated broadband capacity to underserved regions. Its satellites are designed to provide dedicated broadband capacity — not shared like LEO constellation services (Starlink) — to island nations, remote regions, and underserved countries that lack terrestrial broadband infrastructure.
