Momentus Inc. (Nasdaq: MNTS), a small, US-based in-space transportation company, said it has completed the Spacecraft Critical Design Review for its Vigoride 8 mission, according to a company announcement published July 28, 2026, and syndicated via Investing.com. The company said the review covered all of the spacecraft’s subsystems and systems and was carried out during a single nine-hour session.
Momentus describes itself, in its own public materials, as a US commercial space company that provides satellites, satellite components, and in-space transportation and infrastructure services, delivered primarily through its Vigoride line of orbital service vehicles. The company says Vigoride is built to offer hosted payload support, last-mile delivery, and servicing capabilities across a range of mission architectures, and Momentus has said it is working to make new ways of operating in space possible, including through a water-plasma-based propulsion system it has built into its Vigoride vehicles. Completing the Vigoride 8 Spacecraft Critical Design Review is, by the company’s own account, a step toward that broader goal: the review cleared the spacecraft to move out of the design and analysis phase and into procurement and production, advancing a NASA-linked mission that Momentus has said is scheduled to launch in 2027.
According to the announcement, that session was attended by representatives from NASA along with mission customers from Spaceworks, COSMIC, and Juno. Momentus said the Vigoride 8 mission is scheduled to launch in 2027.
The company said it is executing two separate contracts with NASA connected to the Vigoride 8 mission. Under those contracts, according to Momentus, the spacecraft will carry the Spaceworks COSMIC payload and the Juno Rotating Detonation Rocket Engine payload.
The announcement was distributed through Investing.com as a syndication of a Momentus press release dated July 28, 2026. Global Securities News is reporting the contents of that announcement as disclosed by the company and has not independently verified the details of the design review, the nine-hour session, the identities or roles of the NASA and mission-customer attendees, or the terms of the two NASA contracts beyond what Momentus stated in the source material.
