Momentus, a commercial space firm specializing in satellite solutions and in-space infrastructure, announced a three-year reciprocal services agreement with Solstar Space (Solstar). The agreement is designed to utilize the respective strengths, products, and services of each company to deliver comprehensive low Earth orbit (LEO) space capabilities to address a broad range of commercial, government, and space agency requirements.

Solstar provides space-based inter-satellite data relay communications, space-to-ground and local area Wi-Fi systems and services to enhance on-orbit operations. The combined offerings include Solstar Deke Narrowband Space Communicators and Slayton Wideband Space Communicators, Solstar Space Walker Wi-Fi and Solstar Space Airtime and Data Services and Momentus logistics, and deployment services, and ongoing integration of Solstar communications solutions aboard one or more Momentus Orbital Service Vehicle(s).

Founder and CEO, Solstar Space Company, Brian Barnett said, “In-space communications have been severely limited by crucial missing pieces. Outdated space comms approaches originating in the 1960s oftentimes leave space assets disconnected. Solstar is filling those space communications gaps just as Momentus is filling gaps for spacecraft and payload deployment and in-space servicing. Together, we are removing roadblocks to advancing space operations.

“The demand for reliable space connectivity is growing exponentially. Prime space industry drivers we address include Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR) for national security, defense and commercial applications, In-Space Assembly and Manufacturing (ISAM) for space object inspection and relocation, resupply, connecting pre-manufactured components and raw materials, and Rendezvous, Proximity Operations and Docking (RPOD) for spacecraft interaction, refueling, supply and astronaut transfers. These missions cannot operate reliably and securely without persistent space-based communications.

“Our first spaceflight with Momentus is scheduled for February 2026, and we will have the opportunity to work with Momentus partners to demonstrate real-world use cases for ISTAR, ISAM, and RPOD. We are looking forward to the 2026 flight with Momentus, where we will have the opportunity to give the market a glimpse of what we will make possible together.”

Commenting on the Agreement, John Rood, CEO of Momentus Space, said, “We are pleased to deepen our partnership with Solstar Space as we continue to scale our in-space servicing capabilities. This collaboration gives Momentus key advantages to provide resilient spacecraft-to-spacecraft operations, including refueling and repair, on-orbit inspection, and reliable data relay capabilities. Our joint efforts enable enhanced surveillance, situational awareness, and defense-grade support for national security missions. This is particularly important as space becomes increasingly congested. Momentus and Solstar are well-positioned to deliver the end-to-end infrastructure that future space architectures demand. Our 2026 spaceflight will enable our companies to demonstrate real-time, continuous communication with space systems across diverse mission profiles—unlocking greater capabilities for the commercial sector.”
