Impulse Space announced it has raised $150 million in its Series B funding round, led by Founders Fund. The funding attracted both returning investors, such as Lux Capital and Spring Tide, and new participants, including DCVC. Other backers include Airbus Ventures, RTX Ventures, and Tamarack Global, among others. This investment brings the company’s total funding to $225 million, which will be used to scale the team and advance production of its two core vehicles, Helios and Mira.
Impulse’s vehicles offer advanced in-space transportation capabilities, addressing growing demand for more maneuverable and responsive satellite operations. Helios, designed for high-performance payload transfers from Low Earth Orbit (LEO) to Geostationary Earth Orbit (GEO), uses a combination of liquid oxygen and liquid methane to move large payloads within 24 hours. Mira, focused on orbital payload hosting and movement, features a bipropellant propulsion system with non-toxic propellants, supporting enhanced orbital maneuverability for smaller payloads.
The funding marks a milestone year for Impulse, following achievements such as securing two Small Business Innovation Research (SBIR) awards and completing the record-setting LEO Express-1 mission. The company is preparing for the LEO Express-2 mission, where Mira will support multiple customers with payload deployment and hosting services.
With operations based at a 60,000-square-foot headquarters in Redondo Beach, California, and additional testing facilities in Mojave, Impulse is set to continue driving innovation in the in-space transportation sector. The company plans to grow its team and execute key missions, including the first launch of an upgraded Mira design in 2025 and the debut of Helios in 2026.
Founder and CEO Tom Mueller highlighted the importance of this funding for the company’s future, saying “We’re proud to have so many partners who understand and support the importance of our work to accelerate humanity’s future in space by unlocking reliable, affordable, and efficient access to any orbit.”
