NASA and Johns Hopkins University Collaborate on Polylingual Terminal Prototype

NASA and Johns Hopkins University Applied Physics Laboratory (JHU/APL) are partnering to develop a groundbreaking polylingual terminal prototype. The project aims to enhance the agency’s Space Communications and Navigation program. The terminal, known as the Polylingual Experimental Terminal (PExT), will be integrated into a spacecraft bus built by York Space Systems and will undergo a six-month testing period starting June 2024, as part of SpaceX’s Falcon 9 Transporter-11 mission.

One of the key objectives of the PExT testing is its ability to demonstrate contact and link management, as well as forward and return link data flow. This will involve seamless roaming between NASA’s Tracking and Data Relay Satellite network and three commercial relay networks.
Additionally, the performance of the terminal will be evaluated in various mission scenarios, including self-pointing capabilities, waveform adaptation, and protection against command stack failures.

The collaboration between NASA and JHU/APL highlights the significance of the polylingual terminal in enabling efficient and reliable communication in space. This innovative technology could revolutionize the way spacecraft and ground stations exchange data, ultimately improving the overall efficiency and safety of space missions.

By integrating advanced features such as long-term schedule execution, link fault recovery, and reloading, the PExT terminal is expected to provide enhanced flexibility and adaptability for future space missions. Its successful implementation would enable more productive and secure communication between spacecraft and data relay networks, minimizing potential communication breakdowns that could occur in space.

The polylingual terminal prototype developed through this collaboration represents a significant step forward in the field of space communication. As NASA continues to push the boundaries of space exploration, partnerships like these will play a crucial role in unlocking the full potential of space-based technologies. The eventual integration of the PExT terminal into future space missions could pave the way for more sophisticated and efficient communication systems, advancing our understanding of the universe and enabling unprecedented scientific discoveries.
