Momentus Inc. (NASDAQ: MNTS) (“Momentus” or the “Company”), a U.S. commercial space company offering satellite buses, technologies, transportation, and other in-space infrastructure services, today announced it has signed a contract with SpaceX to join an upcoming Transporter rideshare mission launching as soon as early 2026.

Momentus plans to use this port for the launch of its flight-proven Vigoride Orbital Service Vehicle (OSV) to transport a mix of payloads from the U.S. Department of Defense (DoD) and commercial customers to Low-Earth Orbit (LEO).

For this mission, Momentus has additional capacity to support customers planning LEO deployment and hosted payload missions in early 2026. Government and commercial customers interested in utilizing the ability of the Vigoride vehicle to cost-effectively launch and deliver microsatellites up to 200 kg and cubesats, provide average power up to 1kW, and deploy or operate hosted payloads in orbits above 500 km and below the International Space Station are encouraged to contact Momentus while booking opportunities remain open.

“We’re thrilled to be under contract supporting DoD programs, including for our upcoming launch and look forward to also deploying commercial payloads in orbit on this upcoming launch of our Vigoride Orbital Service Vehicle,” said Momentus Chief Executive Officer John Rood. “These exciting collaborations position Momentus at the forefront of the future in-space economy.”

This mission marks Momentus’ fourth Vigoride mission. Customers interested in participating in this mission can contact the Momentus Commercial team at sales@momentusspace.com.
