Interoperable spaceflight computers built from standardized hardware are essential for NASA and its commercial partners to meet development timelines for future lunar infrastructure, according to a NASA official speaking at the 2026 MOSA Industry and Government Summit.
Key Points from the Discussion:
-
Need for Interoperability:
Christopher Green, NASA’s avionics and sensors capability lead, emphasized that adopting interoperability standards is crucial for the success of initiatives like Moonbase and Artemis. He noted that lunar habitats, rovers, and other systems require a cohesive avionics ecosystem that can evolve without necessitating unique computers for each mission. -
SOSA Technical Standard:
The Sensor Open Systems Architecture (SOSA) Technical Standard Space Appendix serves as a framework for applying a modular open systems approach (MOSA) to spaceflight avionics. This standard builds upon the SpaceVPX and VNX+ form factors, facilitating communication across different suppliers’ boards through a standardized backplane. -
Flexibility Over Prescription:
While NASA will not dictate a specific hardware standard for every lunar project, they are encouraging contractors to integrate MOSA principles and let mission-specific needs guide implementations. Green affirmed that a diversified ecosystem of interoperable components enables straightforward decision-making, especially under tight deadlines. -
Engineering Efficiency:
Nicholas Franconi from Voyager Technologies noted that standardized component interfaces simplify engineering processes, allowing more efficient development of space systems as engineers can confidently select compatible components. -
Challenges Remain:
While standardized interfaces are beneficial, the panelists cautioned that they do not negate the need for rigorous space qualifications and system-level testing. Environmental challenges such as radiation and vacuum, as well as thermal management, remain critical considerations.
Conclusion:
As NASA gears up for future lunar missions, adopting standardized and interoperable avionics systems is seen as a key strategy to streamline development and enhance collaboration with commercial partners.
