Momentus: Pioneering cost-effective, water plasma-propelled space transport and services.
Momentus propels its Vigoride vehicle with a proprietary Microwave Electrothermal Thruster that runs on water propellant, which is non-toxic and storable without cryogenic tanks and offers a pathway toward in-situ resource utilization from lunar or asteroid ice. The modular Vigoride architecture hosts customer payloads and performs last-mile orbital delivery within a single bus.
The company holds national-security clearance and serves the U.S. Space Force, DARPA, NASA, and the Missile Defense Agency, including a qualified-vendor slot on the SHIELD contract vehicle. Its in-house Automation and Manufacturing Facility houses cleanrooms, microwave electrothermal thruster vacuum test chambers, and a dedicated Mission Control Center.

Momentus is positioned in an expanding government and commercial space market, forecasting 2026 revenue of $10 million, a ninefold increase over $1.1 million in 2025, driven by milestone-based contracts with NASA and the U.S. Department of Defense. The company also qualified as a vendor on the Missile Defense Agency SHIELD contract vehicle tied to the Golden Dome initiative.
Vigoride 8 is fully subscribed with NASA-awarded contracts for a 2027 launch and Vigoride 9 still has payload capacity available, indicating continued customer demand. A strengthened debt-free balance sheet with roughly $76 million in cash supports investment in satellite technology and orbital transportation services.

Momentus builds the Vigoride Orbital Service Vehicle, a spacecraft bus that launches as a payload on SpaceX Falcon 9 Transporter rideshare missions to low Earth orbit. The vehicle hosts payloads up to roughly 200 kilograms and can generate up to three kilowatts of peak solar power for compute-heavy sensors and robotic payloads.
Through Vigoride, Momentus provides hosted payload support, last-mile delivery to custom operational orbits, and in-orbit servicing for government and commercial customers. The bus has flown repeated missions carrying defense, NASA, and commercial payloads, with subsequent Vigoride vehicles fully booked into 2027.
