en.Wedoany.com Reported - Space mobility technology company Impulse Space has completed a $500 million Series D funding round, co-led by 137 Ventures and BANNER VC, bringing its total cumulative funding to over $1 billion. The funds will be used to expand hiring and manufacturing capabilities, and to build space mobility infrastructure, covering the vehicles, propulsion systems, and operational architecture required for spacecraft movement in space after launch.
Impulse Space has executed three successful launch missions and holds hundreds of millions of dollars in customer contracts. It is scaling up to meet the growing demand for space mobility across commercial, civil, and government sectors. While launch activities have become increasingly frequent over the past decade, the maneuverability of spacecraft after orbital insertion remains limited, often confining them to a single orbit or subjecting them to slow and costly orbital transfer processes.
The company believes that developing spacecraft specifically designed for space mobility and building a new orbital infrastructure layer are key to accelerating human expansion into space and unlocking the potential of the space economy. Such advanced mobility capabilities enable spacecraft to move quickly, precisely, and cost-effectively after launch, allowing for flexible deployment, repositioning, or mission changes, thereby creating new opportunities for commercial, civil, and government missions in low Earth orbit and beyond.
Tom Mueller, founder and CEO of the company, stated that Impulse Space is building not just spacecraft, but the economic and technological engine to power human expansion into space, and that the ability to move quickly, precisely, and cost-effectively in orbit is the foundation for realizing a true space age.
Impulse Space's initial spacecraft series include the Mira precision maneuver spacecraft, the Helios high-energy upper stage, and the Caravan rideshare program. Mira has already executed multiple missions, achieving record-breaking orbital changes and in-orbit operations, including autonomous rendezvous and proximity operations. Helios is scheduled for its first flight in 2027, aiming to deliver payloads to distant orbits in a fraction of the time and cost of traditional methods. The Caravan program is focused on reducing the cost of accessing high-energy orbits such as geosynchronous orbit.
In terms of propulsion systems, the company has developed Saiph (for precision maneuvering and orbital repositioning), Deneb (for high-energy long-distance transport), and Rigel (a throttleable application suitable for landers and responsive maneuvers). Impulse is building a full-spectrum space mobility infrastructure, encompassing multiple spacecraft and propulsion systems under development.
Justin Fishner-Wolfson, Managing Partner at 137 Ventures, noted that Impulse is addressing the next major challenge in the industry—space mobility—a capability of strategic importance that will define the next phase of the space economy. Adam Ramada, Managing Partner at BANNER VC, stated that as orbital activity increases, space mobility becomes foundational, and Impulse is building the infrastructure to drive the next layer of growth in the space economy. Other investors in this round include Founder's Fund, Lux Capital, and Linse Capital.
Impulse Space will use the funds to expand its team and manufacturing capabilities. The company has more than doubled its workforce over the past year and is currently recruiting for over 200 open positions in areas such as propulsion, avionics, autonomous systems, spacecraft systems, manufacturing, and mission operations. The company's facilities span Redondo Beach, California; Boulder, Colorado; Washington, D.C.; and a testing environment under construction in Mojave, California. Eric Romo, President and Chief Operating Officer, stated that demand for space mobility is exceptionally high, and the funding will support the company in scaling up without compromising quality or execution speed.
