NASA Tested Advanced Lunar Landing Technology
Researchers successfully evaluated the new navigation system during a recent flight test in California.
Updated on Sept. 24, 2026 in Space
On August 27, 2026, NASA engineers conducted a successful flight test of the Safe and Precise Landing - Integrated Capabilities Evolution (SPLICE) experiment. The test utilized an Alta-X drone near the Armstrong Flight Research Center to simulate complex landing maneuvers.
Why it matters
The SPLICE technology is designed to enable spacecraft to land in difficult or unexplored regions of the Moon, Mars, and other icy worlds. Developing these advanced guidance systems is essential for future missions seeking to access remote scientific targets.
The SPLICE system utilizes specialized navigation, guidance, and processing hardware developed at the Johnson Space Center. Testing involved an Alta-X drone executing high-fidelity descent maneuvers to validate the system's flight performance.
The players
NASA
The United States government agency responsible for the nation's civilian space program and for aeronautics and space research.
Johnson Space Center
A NASA facility in Houston that serves as the home of the United States human spaceflight training and research operations.
Armstrong Flight Research Center
A NASA center located in Edwards, California, that serves as the agency's primary site for atmospheric flight research and testing.
The details
Engineers from the Johnson Space Center designed the SPLICE system to manage precision guidance tasks that are critical for autonomous planetary landings. By simulating descent patterns, the team confirmed that the technology can handle the complex calculations required for safe touchdown in unknown terrain.

The Big Picture
This success shifts the scientific focus toward fully autonomous landing capabilities required for the Artemis lunar exploration program. The development of SPLICE effectively bridges the gap between theoretical guidance models and the practical requirements for landing on remote celestial bodies.
Advancements in autonomous landing technology provide a pathway for future spacecraft to explore previously unreachable areas of icy worlds and distant planets. These technical milestones will eventually enable the collection of new scientific data from regions that were previously too hazardous for manual landing approaches.
The takeaway
The successful testing of the SPLICE system marks a significant step toward achieving precise, autonomous planetary landings. This technology will be vital for future missions that require high-accuracy navigation in environments where human or remote manual control is not feasible.
