A groundbreaking technology designed to enable spacecraft to autonomously navigate to safe landing sites on the Moon and other planetary bodies has successfully completed a critical demonstration. The Safe and Precise Landing – Integrated Capabilities Evolution (SPLICE) system, developed by researchers, recently showcased its advanced capabilities during simulated lunar descent and landing maneuvers.

The demonstration involved an Alta-X drone equipped with the SPLICE guidance, navigation, and control payload. Conducted on August 27 at Rogers Dry Lake near the Armstrong Flight Research Center in Edwards, California, the tests validated the system’s ability to map terrain, assess potential landing areas, and autonomously divert to a safer location if hazards were detected. SPLICE achieves this by generating high-resolution digital elevation maps using light-detection and sensor data, ensuring precision and safety during critical landing phases.

The SPLICE payload was developed at the Johnson Space Center in Houston, with specialists at Armstrong assisting with its integration, testing, and flight aboard the Alta-X drone in June and July. These initial tests confirmed robust communications, data handling, telemetry, and command-control performance. According to Davis Adams, the project manager, this flight test represents the culmination of nearly a decade of dedicated work, significantly advancing the technology’s readiness level for future space missions.

This crucial validation primes SPLICE for integration into upcoming robotic and crewed lunar flights, with its guidance and navigation systems applicable to terrestrial, lunar, and Martian descent and landing missions. Collaboration with commercial lunar lander providers is already underway, with many leveraging data from SPLICE’s development for their own platforms. The system is expected to be available in a software catalog this fall, and industry partners are actively evaluating its navigation capabilities for precision landing and potential extensions for autonomous surface mobility, marking a pivotal step towards safer and more efficient space exploration.
