Momentus Inc. is a space logistics and in-space transportation company that develops and operates orbital transfer vehicles (OTVs) to move satellites and other payloads between orbits. Its core offering, the Vigoride platform, uses a proprietary water plasma propulsion system to provide sustainable, high-efficiency thrust for a range of orbital maneuvers. The company’s solutions are designed to enable flexible deployment and repositioning of satellites after launch, assisting satellite operators in optimizing mission lifespans and orbital slots.
Founded in 2017 and headquartered in Santa Clara, California, Momentus has pursued a path of technology demonstration and commercialization. In late 2021, the company completed a business combination with Stable Road Acquisition Corp., enabling its listing on the Nasdaq under the ticker MNTS. After initial in-space tests faced regulatory and technical hurdles, Momentus has continued to refine its propulsion systems and secure approvals from U.S. authorities for future demonstration and commercial missions.
Momentus serves commercial satellite operators, government agencies and research institutions with missions that range from rideshare deployments to dedicated orbital transfers. By offering secondary transport and ride-sharing options, the company aims to reduce the complexity and cost of reaching precise orbital altitudes, inclinations and other parameters. Its systems are designed to accommodate small satellites as well as larger spacecraft seeking orbit adjustments, refueling services or orbital maintenance.
Leadership at Momentus includes CEO John Rood, who joined the company following a career in national security and defense analysis, bringing experience in aerospace policy and program management. Under his guidance, Momentus continues to advance its water plasma thruster technology and build partnerships with launch providers, satellite integrators and governmental entities. The company’s broader mission is to create an accessible in-space infrastructure that supports a growing global space economy.
