What's Happening?
NASA has successfully demonstrated a new technology called the Polylingual Experimental Terminal (PExT), which allows space missions to switch seamlessly between government and commercial communications
networks. This advancement is expected to improve the reliability of data transmission for NASA missions, enabling them to navigate, monitor spacecraft health, and transmit scientific information back to Earth with fewer interruptions. The technology was tested aboard the York Space Systems’ BARD mission, which launched into low Earth orbit. The demonstration involved NASA's Tracking and Data Relay Satellite fleet and commercial networks operated by SES Space & Defense and Viasat. The PExT technology supports wideband data exchange across a broad range of frequencies, facilitating interoperability between government and commercial assets.
Why It's Important?
The successful demonstration of PExT technology marks a significant step forward for NASA and the U.S. satellite communications industry. By enabling seamless communication across different networks, this technology could lead to more efficient and reliable space missions. It also supports NASA's goal of advancing the commercialization of space communications, potentially reducing costs and increasing the flexibility of future missions. The ability to integrate new capabilities from commercial providers even after launch could enhance mission performance and resilience. This development is particularly important as NASA plans to expand its capabilities to the Moon and Mars, where reliable communication is crucial for mission success.
What's Next?
NASA has extended the PExT demonstration for an additional 12 months to continue testing its capabilities. Future operations will include new direct-to-Earth tests with the Swedish Space Corporation, scheduled to begin in early 2026. The technology demonstration will continue through April 2027, with plans for NASA to purchase satellite relay services for science missions in low Earth orbit from U.S. companies by 2031. This ongoing testing and development will help ensure that NASA's future missions can benefit from the enhanced communication capabilities provided by wideband technology.
