Impulse Space, founded in 2021 by Tom Mueller, is headquartered in Redondo Beach, California. The company is a trailblazer in the field of in-space transportation and logistics, with a mission to accelerate humanity’s future in space. Specializing in orbital transfer vehicles (OTVs) and propulsion systems, Impulse Space provides efficient payload delivery and hosting services across Low Earth Orbit (LEO), Medium Earth Orbit (MEO), Geostationary Orbit (GEO), and beyond. With a team of aerospace veterans and partnerships with leading organizations like SpaceX and the U.S. Space Force, Impulse Space is redefining the possibilities of space exploration and logistics.
Technology & Innovation

Impulse Space is at the forefront of technological innovation in the aerospace industry, leveraging advanced engineering and design to create cutting-edge solutions for in-space transportation. The company’s flagship vehicles, Mira and Helios, are designed to address the challenges of last-mile delivery and high-energy orbital transfers.
The Mira vehicle, approximately the size of a dishwasher, is a compact orbital transfer vehicle equipped with Saiph thrusters. These thrusters use a nontoxic bipropellant system, offering a specific impulse of 290 seconds. Mira is capable of delivering payloads from LEO to GEO with precision, making it ideal for constellation deployment, hosted payload services, and precision reentry missions. Its modular design allows for adaptability across various mission profiles, ensuring reliability and efficiency.
Helios, on the other hand, is a high-energy kick stage designed for direct-to-GEO missions and beyond. Powered by the Deneb engine, Helios uses liquid oxygen and liquid methane propellants, enabling it to transport payloads of up to 5 tons from LEO to GEO in less than 24 hours. The vehicle’s advanced propulsion system and high delta-v capability make it suitable for a wide range of applications, including lunar and interplanetary exploration. Helios is compatible with most medium-lift launch vehicles, offering flexibility and scalability for diverse mission requirements.
Impulse Space’s vertically integrated manufacturing approach sets it apart from competitors. The company produces thrusters, valves, avionics, and other critical components in-house, ensuring quality control and reducing costs. This integration allows Impulse Space to deliver innovative solutions on schedule and within budget, enhancing its reputation as a reliable partner in the aerospace industry.

Recent Developments & Achievements
Impulse Space has recently achieved significant milestones, showcasing its capabilities and commitment to innovation. The company successfully completed its inaugural mission, LEO Express-1, which demonstrated the capabilities of the Mira vehicle. This mission marked a significant step forward in the field of in-space transportation, proving the reliability and efficiency of Impulse Space’s technologies.
In 2024, Impulse Space secured a $150 million Series B funding round led by Founders Fund, bringing its total funding to $225 million. This funding will support the ongoing production of the Helios and Mira vehicles, as well as the expansion of the company’s team and facilities. The funding round also included participation from prominent investors like Airbus Ventures and Lux Capital, highlighting the industry’s confidence in Impulse Space’s vision and capabilities.
The company has also been awarded a $60 million Strategic Funding Increase (STRATFI) by SpaceWERX, the innovation arm of the U.S. Space Force. This award will support the development of the Helios vehicle for tactically responsive GEO missions, further solidifying Impulse Space’s position as a leader in the aerospace industry.
Additionally, Impulse Space is preparing for the launch of its LEO Express-2 mission, which will provide deployment and hosting services for multiple customers. The company’s vertically integrated 60,000-square-foot headquarters in Redondo Beach, California, serves as the hub for vehicle design, manufacturing, testing, and assembly, ensuring seamless execution of its ambitious projects.
