REDONDO BEACH, Calif., June 02, 2026 (GLOBE NEWSWIRE) -- Impulse Space, the in-space mobility leader, today announced it has raised $500 million in Series D funding. The round was co-led by 137 Ventures and BANNER VC, bringing the company's total capital raised to over $1 billion.
The funding will support hiring and manufacturing growth as the company scales its effort to build in-space mobility infrastructure: the vehicles, propulsion systems, and operational architecture that determine where and how spacecraft move after launch.
With three missions flown and hundreds of millions of dollars in customer contracts, Impulse is growing to meet surging demand for in-space mobility across commercial, civil, and government sectors.
Unlocking Mobility Beyond Launch
Over the past decade, launch has become more accessible and frequent. But once in orbit, spacecraft have remained constrained in their ability to move. Historically, spacecraft have been locked into a single orbit following launch or faced with slow, expensive transfers.
In order to accelerate humanity's future beyond Earth, unlock a robust space economy, and realize a true space age, a new layer of orbital infrastructure must be developed: spacecraft that are purpose-built for in-space mobility.
Impulse is designing, building, testing, and flying those spacecraft.
Advanced in-space mobility, the ability to move quickly, precisely, responsively, and affordably after launch, is a required capability for the next phase of the space economy. It allows spacecraft to be placed, repositioned or re-tasked, and operated with unprecedented flexibility. And with that, it transforms how missions are designed and unlocks new opportunities across commercial, civil, and government missions, both in and well beyond Earth's immediate orbits.
"We're building more than spacecraft: we're building the economic and technical engine that will power humanity's expansion into space," said Tom Mueller, ...
