Airbus Ventures announced its follow-on investment in Impulse Space, a leader in the development of in-space transportation services, which has just raised a $150 million Series B funding round. 

The funding, which follows a series of recent milestone moments for the company, will be used to further grow the Impulse team and to support the ongoing production of both their Helios and Mira vehicles. The Series B round brings Impulse’s total funding to date to $225 million.

“This funding is not only a testament to our team's achievements over the past year but also a validation of our vision for the in-space transportation industry,” said Tom Mueller, founder and CEO of Impulse Space. 

“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.”

The Series B funding adds further momentum to Impulse’s continuing advances. This year alone, the company has been selected by SpaceWERX for a Strategic Funding Increase(STRATFI) award, two Small Business Innovation Research Program(SBIR) awards, announced a new GEO Rideshare Program, and completed their record-setting LEO Express-1 mission. 

The team is currently preparing for the upcoming launch of the LEO Express-2 mission, which will see a Mira vehicle support deployment and hosting services for multiple customers.

Operations are based out of Impulse’s 60,000-square-foot headquarters in Redondo Beach, California, where the company handles the majority of vehicle design, manufacturing, testing, and assembly under one roof. 

Impulse also operates facilities at the Mojave Air and Space Port, where additional testing work is underway for the Helios Deneb engine.

Impulse Space’s vehicles, Helios and Mira, stand out in two key ways from other market entrants. Each features predominantly in-house components, from thrusters and valves to star trackers and avionics. 

This vertically-integrated approach enables the team to advance innovation and improve reliability while staying on time and on budget. Second, both vehicles offer a high delta-v capability due to their chemical propulsion systems, which also feature non-toxic propellants, simplifying mission operations.

Helios, a high-performance kick stage, uses liquid oxygen and liquid methane to transport more than 5 tons of payload from LEO to GEO in less than 24 hours. 

Mira, designed for payload hosting, deployment, and movement within orbits, uses a storable nitrous oxide and ethane bipropellant to offer up to 900m/s of delta-v for a 100kg payload.

“Impulse Space has quickly become a world leader in the development of in-space transportation services for the inner Solar System,” remarks Airbus Ventures Managing Partner, Thomas d’Halluin.
