About Impulse Space
Impulse Space, the in-space mobility leader, is accelerating our future beyond Earth beginning with its fleet of cost-effective, high-performance space vehicles: Helios and Mira.
The Helios kick stage unlocks high-energy orbits with its powerful Deneb engine, rapidly transporting payloads from LEO to MEO, GEO, heliocentric, lunar, and other planetary orbits.
The flight-proven Mira enables precise maneuverability and rapid responsiveness for hosting, deployment, and rendezvous and proximity operations (RPO) across any orbit.
Founded by Tom Mueller and led by a team of industry pioneers, Impulse Space is transforming in-space mobility by reliably and rapidly getting customers where they want to go. And they're just getting started.
"From the beginning, C4 has shown a clear interest in the scope of what we’re building at Impulse — not just the technology, but also the long-term vision and the operational discipline behind it. They ask thoughtful questions, offer grounded perspectives, and have been engaged in key parts of the journey. C4 isn’t just investing in space — they’re paying attention to how it’s being built."
