Momentus Reports Strong Progress of in-Space Robotic Assembly Under U.S. Department of War Contract

Hosted payload operations on Vigoride 7 spacecraft support cutting-edge missions of U.S. government and commercial customers

SAN JOSE, Calif.--(BUSINESS WIRE)--Momentus Inc. (NASDAQ: MNTS) (“Momentus” or the “Company”), a U.S. commercial space company specializing in satellite technology solutions, space transportation, and on‑orbit services, today announced continued progress on the robotic assembly in space of modular components for a complex truss structure under a contract with the Defense Advanced Research Projects Agency (DARPA). Trusses are important structures in engineering that are used in a variety of applications; from bridges and roofs to parts of the International Space Station and communications dishes.

Under the DARPA contract for the Novel Orbital and Moon Manufacturing, Materials and Mass‑Efficient Design (NOM4D) program, Momentus managed the integration and launch, and is providing on-orbit support, to a payload from Caltech known as ASTRA — the Autonomous in‑Space Tensioned Reflector Assembly. ASTRA is one of 10 payloads carried by the Momentus Vigoride 7 orbital service vehicle launched to low Earth orbit (LEO) on March 30, 2026, aboard the SpaceX Transporter 16 mission.

“Our engineering team is advancing cutting-edge work and navigating the harsh environment in space, supporting critical priorities for the U.S. military and commercial customers,” said Momentus CEO John Rood. “Autonomous operations in space and in-space assembly have great potential to transform essential services like communications with greater capability and lower costs.”

The Caltech payload has made significant progress in completing the first three phases of its autonomous modular structure build, marking meaningful progress demonstrating in‑space assembly of complex structures. Caltech plans to robotically assemble a 1.4-meter-diameter dish reflector to serve as a proof of concept for a larger 100-meter diameter dish reflector for communications and other applications.

Momentus’ Vigoride 7 orbital service vehicle is meeting all mission objectives since launch in March. The company’s Vigoride 8 mission, scheduled to fly in 2027, is fully booked supporting NASA payloads. Momentus still has capacity available on the Vigoride 9 mission planned for late 2027.
