About Momentus


Momentus plans to offer in-space infrastructure services by building transfer and service vehicles that will carry satellites and hosted payloads between orbits in space using an innovative water-based microwave electrothermal (MET) propulsion system. In addition to space transportation services, we intend to offer other infrastructure services including dead satellite removal, inspection, and other satellite-to-satellite service offerings. To execute these missions, we are designing a family of three progressively larger and more capable vehicles, including Vigoride, which we plan to begin flying in 2022, Ardoride in 2024 and Fervoride in 2026.
