Impulse CEO Tom Mueller was a founding member of SpaceX.

Impulse Space, an in-space transportation services startup launched in 2021 by SpaceX founding member Tom Mueller, has secured $10 million in funding from Lux Capital. This brings Impulse Space’s recent funding total to $30 million after it raised $20 million in a seed funding round led by Founders Fund.

“With funding from Lux Capital, Impulse continues to build on a solid financial foundation and an equally strong foundation of the amazing people supporting us,” Mueller said in a statement. “Especially for a company like Impulse Space, it’s important to be aligned with people and organizations that trust in our technologies and capabilities as much as we do.”

Lux Capital is an investment firm co-founded by managing partners Peter Hébert and Josh Wolfe.

Impulse aims to provide last-mile space payload delivery services spanning in-space transportation, orbital transport of satellites to optimal orbits, in-orbit servicing, space debris deorbit and space station orbit keeping. The company’s team members have developed products for organizations such as SpaceX, NASA, GE, Joe Gibbs Racing, and Virgin.
