Momentus Completes Key Milestone for Next Launch of Spacecraft with Customer Payloads

Momentus Inc. (NASDAQ: MNTS), a U.S. commercial space company offering satellite buses, satellite components, and in-space infrastructure services, today announced the successful completion of Environmental Testing of its Vigoride-7 Orbital Service Vehicle, scheduled to launch aboard SpaceX's Transporter-16 mission targeted for launch no earlier than March 2026. Vigoride 7 is scheduled to carry payloads for several customers, including the U.S. Defense Department, NASA, and commercial customers, that will generate new revenue.

The rigorous testing campaign included

• Thermal Testing, which simulated the extreme temperature swings of space to validate spacecraft performance and reliability; and

• Vibration Testing conducted at Experior Laboratories, which exposed Vigoride-7 to the mechanical stresses of launch conditions.

Tom Malko, SVP Engineering and Operations of Momentus, commented: “Completing thermal and vibration testing is a critical milestone for Vigoride-7. These campaigns validate that our spacecraft can withstand the demanding conditions of launch and the space environment, giving our customers confidence in mission success.”

Momentus continues to advance its vision of providing flexible, affordable, and reliable in-space transportation and services, supporting the growing demand for satellite deployment, orbital logistics, and pioneering in-space assembly missions.
