SANTA CLARA, Calif., July 29, 2021--(BUSINESS WIRE)--Momentus Inc. ("Momentus" or the "Company"), a U.S. commercial space company that plans to offer in-space infrastructure services, today announced that its latest-generation Microwave Electrothermal Thruster (MET) has completed 350 test cycles during the initial stages of "life testing" - the final stage of the thruster’s ground test campaign. The testing to date has produced results that are consistent with the Company’s expectations for engine performance and the resilience of the engine design for the time tested.

This latest-generation thruster improves on earlier thruster designs by incorporating several design innovations to the nozzle to extend the thruster’s total lifetime. The thruster is expected to extend Vigoride's range and pave the way for ultra-long-life thrusters needed for future reusable vehicles. Momentus is developing Vigoride to support services in Low-Earth Orbit. The Company has completed the manufacturing of two Vigoride vehicles, one with a 30W thruster and a second with a 550W thruster. A third Vigoride vehicle is currently in build and incorporates a 750W thruster.
"The latest-generation thruster has reached 350 cycles with no detectable performance degradation," said Momentus Chief Technology Officer Rob Schwarz. "We have been undertaking a comprehensive ground test campaign that we anticipate completing in November of this year. Our objective is to validate the thruster’s performance which includes thrust, specific impulse, and achievable lifetime."
The ground test campaign is expected to serve as a stepping stone to future in-space demonstrations, which the Company is targeting to begin with its inaugural flight of Vigoride slated for no earlier than June 2022. Vigoride’s first flight is expected to provide essential on-orbit functional proof of principle and performance verification data for its MET technology. This data will be used to assess the efficacy of the MET, and identify potential refinements or upgrades for future versions of the MET.
Momentus believes that its MET technology can provide a unique competitive advantage for its vehicles and services. The MET water plasma-based thruster was launched in July 2019 in a mission known as El Camino Real. The mission did not meet its pre-launch success criteria. At the same time, Momentus believes there were aspects of the mission that were clearly significant. El Camino Real was the first time an MET thruster was fired in space, and also the first time a water plasma-based propulsion system was used for the firing of a thruster in space. Since then, the Company has continued to evolve its design. The latest 750W thruster now in ground-testing is approximately 25 times more powerful than the original thruster design.
