Momentus Announces Continued Progress On Robotic Assembly In Space Of Modular Components For Complex Truss Structure Under Contract With Defense Advanced Research Projects Agency

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

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.
