en.Wedoany.com Reported - The Polylingual Experimental Terminal (PExT), developed by NASA, has completed its initial demonstration phase, designed to enable interoperability between different satellite relay networks. In a June 1 update, NASA stated that due to its successful performance and technical flexibility, PExT will continue operations to explore new partnership opportunities and conduct additional capability demonstrations.

In 2025, PExT was launched aboard a BARD spacecraft from York Space Systems via a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, entering a high-inclination low Earth orbit. The terminal has successfully validated Ka-band broadband spectrum communication technology, enabling space missions to relay data between government and commercial networks. NASA's goal in advancing this technology is to pave the way for transitioning all its near-Earth communication relay services to commercial providers.

Previously, satellite communications were typically limited to a single network. Developed by the Johns Hopkins University Applied Physics Laboratory in collaboration with NASA's Space Communications and Navigation program, PExT has achieved data transmission across multiple commercial and government satellite systems. In December 2025, the terminal's demonstration mission met its primary objective: successfully transmitting data back to Earth via NASA's Tracking and Data Relay Satellite System and commercial satellite networks operated by Viasat and SES Space and Defense.

The extended operational phase of PExT began in January and will continue through April 2027. Future plans include demonstrating direct-to-Earth forward and return links using SSC Space's global ground station network, including 50 direct-to-Earth link tests using SSC Space's partner ground station in Germany, Weilheim. NASA's mission update noted that these demonstrations aim to show how missions can flexibly route data via relay satellites or direct-to-Earth links to enhance communication resilience, coverage, and operational efficiency.

Meanwhile, NASA is collaborating with Aalyria Technologies to demonstrate what it calls enterprise service operations. This demonstration will use Aalyria's Spacetime software to provide coordinated planning, management, and communication support for multiple missions through a shared software framework. NASA's update stated that this aims to demonstrate how these frameworks can streamline operational processes, improve service visibility, and ensure reliable communication support throughout a mission's lifecycle.

This work builds on several years of collaboration between the Defense Innovation Unit and Aalyria under the Hybrid Space Architecture program. As a U.S. Department of Defense initiative, the program aims to build a more connected, resilient, and interoperable space network ecosystem, enabling government and commercial satellite systems to operate seamlessly together.
