NASA’s SPLICE Navigation Tech Aces Drone Test, Paving Way for Safer Moon and Mars Landings

NASA has successfully tested a new autonomous navigation system that could transform how spacecraft land on the Moon and other planets. On August 27, an Alta-X drone carrying the Safe and Precise Landing – Integrated Capabilities Evolution (SPLICE) payload performed simulated lunar descent and landing maneuvers, demonstrating the technology’s ability to guide a vehicle to a safe touchdown without human intervention. The test is a major step toward enabling future robotic and crewed missions to land in scientifically rich but hazardous terrain that current systems cannot safely access. SPLICE uses advanced sensors and algorithms to detect surface hazards in real time and adjust the landing trajectory accordingly. NASA’s Langley Research Center in Hampton, Virginia, led the flight test, which builds on years of development and ground testing. The success brings the agency closer to integrating SPLICE into commercial lunar landers and, eventually, Mars missions, reducing risk and expanding exploration possibilities. With this milestone, NASA is one step closer to routine, pinpoint landings on other worlds.
