Vigoride 7 continues to demonstrate milestone execution in a multi-payload mission with complex on-orbit operations

Momentus Inc. (NASDAQ:MNTS)("Momentus"or the "Company"), a U.S. commercial space company specializing in satellite technology, space transportation, and in-orbit services, today announced its Vigoride 7 Orbital Service Vehicle (OSV) has successfully completed another key milestone during its mission, which is scheduled to last for several months. The Vigoride 7 mission began on March 30, 2026 when the OSV was launched to low-Earth orbit on the SpaceX Transporter 16 mission. The Vigoride 7 OSV is carrying 10 payloads for a range of customers including NASA and U.S. Defense Department/Department of War organizations and commercial customers.

The Vigoride 7 OSV has completed a series of orbit-lowering maneuvers, reducing its altitude nearly 20 km through more than 50 controlled and precisely timed operations of both of its on-board Microwave Electrothermal Thrusters (METs) that utilize water as its propellant. The innovative Momentus MET has now cumulatively been used over 400 times to maneuver the Vigoride spacecraft on the Company’s missions since 2023 demonstrating the maturity of this proprietary system.
