Impulse Space raised $300 million in its latest funding round as the US-based startup looks to cash in on demand for its highly agile spacecraft. Led by Tom Mueller, a founding member and employee No. 1 at Elon Musk’s SpaceX, Impulse Space develops spacecraft that can haul satellites across different orbits – known as “space tugs” in the industry. The company so far has two such vehicles: the smaller Mira craft, which has flown two missions, and Helios, which can maneuver heavier payloads and will begin flying in 2026.
The Series C funding round was led by Linse Capital and included Peter Thiel’s Founders Fund, Valor Equity Partners, Airbus Ventures, RTX Ventures and new investor DFJ Growth, Impulse said. Space tugs are useful for satellite operators who want their craft to reach a specific orbit but don’t want to pay for a customized launch or spend a lot of time transitioning their vehicle to a custom orbit. “Most commercial customers will take a very slow transfer orbit to get to their final destination. That will take anywhere from six to 10 months. Helios will get you there the same day you launch,” Eric Romo, president of Impulse Space, said in an interview. “That time is worth money.” Romo declined to comment on the company’s valuation but said, with the latest round, California-based Impulse has raised $525 million.
