Impulse Space develops orbital transfer vehicles that function as last-mile transportation infrastructure for satellites and payloads across Earth orbit and beyond. Founded in 2021 by Tom Mueller - the propulsion engineer behind SpaceX's Falcon engine family - the company operates two primary vehicle platforms: Mira, an agile orbital transfer vehicle for maneuvering payloads between orbits, and Helios, a high-performance kick stage designed for LEO-to-GEO transport. The vehicles support mission profiles ranging from LEO Express rideshare services to cislunar and lunar operations, serving commercial, civil, and government customers.
The engineering organization includes veterans from SpaceX, TRW, and other aerospace programs, now numbering approximately 80 employees. Technical work spans propulsion system development, avionics integration, and autonomous control systems for spacecraft operating across multiple orbital regimes. The company has raised over $525 million from investors including Founders Fund and Lux Capital, funding the development and flight validation of its vehicle platforms.
Impulse Space's approach addresses the orbital mobility gap between launch vehicle separation and final operational orbit - analogous to ground transportation's last-mile problem. The vehicles provide delta-v capability and precision maneuvering to position payloads in specific orbits that rideshare launch profiles cannot directly access, expanding operational flexibility for satellite operators and space stations without requiring dedicated launch vehicles for each destination orbit.
