Impulse Space, founded in 2021 by ex-SpaceX engineer Tom Mueller, is an in-space transportation company and space tug provider. It develops orbital transfer vehicles like Mira and Helios to move satellites and payloads from LEO to other orbits, including GEO, lunar, and Martian destinations. Impulse Space has partnered with companies like Relativity Space, Exolaunch, and Anduril, and was selected by NASA as a launch service provider under the VADR contract.
