Landing on the Moon is not easy, particularly when a crew or spacecraft must meet exacting requirements. For Artemis missions to the lunar surface, those requirements include an ability to land within an area about as wide as a football field in any lighting condition amid tough terrain.
NASA’s official lunar landing requirement is to be able to land within 50 meters (164 feet) of the targeted site and developing precision tools and technologies is critically important to mission success.
NASA engineers recently took a major step toward safe and precise landings on the Moon – and eventually Mars and icy worlds – with a successful field test of hazard detection technology at NASA’s Kennedy Space Center Shuttle Landing Facility in Florida.
A joint team from the Aeroscience and Flight Mechanics Division at NASA’s Johnson Space Center’s in Houston and Goddard Space Flight Center in Greenbelt, Maryland, achieved this huge milestone in tests of the Goddard Hazard Detection Lidar from a helicopter at Kennedy in March 2025.
NASA’s Hazard Detection Lidar field test team at Kennedy Space Center’s Shuttle Landing Facility in Florida in March 2025. NASA The new lidar system is one of several sensors being developed as part of NASA’s Safe & Precise Landing – Integrated Capabilities Evolution (SPLICE) Program, a Johnson-managed cross-agency initiative under the Space Technology Mission Directorate to develop next-generation landing technologies for planetary exploration. SPLICE is an integrated descent and landing system composed of avionics, sensors, and algorithms that support specialized navigation, guidance, and image processing techniques. SPLICE is designed to enable landing in hard-to-reach and unknown areas that are of potentially high scientific interest.
The lidar system, which can map an area equivalent to two football fields in just two seconds, is a crucial program component. In real time and compensating for lander motion, it processes 15 million short pulses of laser light to quickly scan surfaces and create real-time, 3D maps of landing sites to support precision landing and hazard avoidance.
Those maps will be read by the SPLICE Descent and Landing Computer, a high-performance multicore computer processor unit that analyzes all SPLICE sensor data and determines the spacecraft’s velocity, altitude, and terrain hazards. It also computes the hazards and determines a safe landing location. The computer was developed by the Avionics Systems Division at Johnson as a platform to test navigation, guidance, and flight software. It previously flew on Blue Origin’s New Shepard booster rocket.
The NASA team prepares the Descent and Landing Computer for Hazard Detection Lidar field testing at Kennedy Space Center. NASA For the field test at Kennedy, Johnson led test operations and provided avionics and guidance, navigation, and control support. Engineers updated the computer’s firmware and software to support command and data interfacing with the lidar system. Team members from Johnson’s Flight Mechanics branch also designed a simplified motion compensation algorithm and NASA’s Jet Propulsion Laboratory in Southern California contributed a hazard detection algorithm, both of which were added to the lidar software by Goddard. Support from NASA contractors Draper Laboratories and Jacobs Engineering played key roles in the test’s success.
Primary flight test objectives were achieved on the first day of testing, allowing the lidar team time to explore different settings and firmware updates to improve system performance. The data confirmed the sensor’s capability in a challenging, vibration-heavy environment, producing usable maps. Preliminary review of the recorded sensor data shows excellent reconstruction of the hazard field terrain.

NASA Beyond lunar applications, SPLICE technologies are being considered for use on Mars Sample Return, the Europa Lander, Commercial Lunar Payload Services flights, and Gateway. The DLC design is also being evaluated for potential avionics upgrades on Artemis systems.
Additionally, SPLICE is supporting software tests for the Advancement of Geometric Methods for Active Terrain Relative Navigation (ATRN) Center Innovation Fund project, which is also part of Johnson’s Aeroscience and Flight Mechanics Division. The ATRN is working to develop algorithms and software that can use data from any active sensor – one measuring signals that were reflected, refracted, or scattered by a body’s surface or its atmosphere – to accurately map terrain and provide absolute and relative location information. With this type of system in place, spacecraft will not need external lighting sources to find landing sites.
With additional suborbital flight tests planned through 2026, the SPLICE team is laying the groundwork for safer, more autonomous landings on the Moon, Mars, and beyond. As NASA prepares for its next era of exploration, SPLICE will be a key part of the agency’s evolving landing, guidance, and navigation capabilities.

NASA researchers are sending three air quality monitors to the International Space Station to test them for potential future use on the Moon.Credit: NASA/Sara Lowthian-Hanna As NASA prepares to return to the Moon, studying astronaut health and safety is a top priority. Scientists monitor and analyze every part of the International Space Station crew’s daily life—down to the air they breathe. These studies are helping NASA prepare for long-term human exploration of the Moon and, eventually, Mars.
As part of this effort, NASA’s Glenn Research Center in Cleveland is sending three air quality monitors to the space station to test them for potential future use on the Moon. The monitors are slated to launch on Monday, April 21, aboard the 32nd SpaceX commercial resupply services mission for NASA.
Like our homes here on Earth, the space station gets dusty from skin flakes, clothing fibers, and personal care products like deodorant. Because the station operates in microgravity, particles do not have an opportunity to settle and instead remain floating in the air. Filters aboard the orbiting laboratory collect these particles to ensure the air remains safe and breathable.
Astronauts will face another air quality risk when they work and live on the Moon—lunar dust.
“From Apollo, we know lunar dust can cause irritation when breathed into the lungs,” said Claire Fortenberry, principal investigator, Exploration Aerosol Monitors project, NASA Glenn. “Earth has weather to naturally smooth dust particles down, but there is no atmosphere on the Moon, so lunar dust particles are sharper and craggier than Earth dust. Lunar dust could potentially impact crew health and damage hardware.”
Future space stations and lunar habitats will need monitors capable of measuring lunar dust to ensure air filtration systems are functioning properly. Fortenberry and her team selected commercially available monitors for flight and ground demonstration to evaluate their performance in a spacecraft environment, with the goal of providing a dust monitor for future exploration systems.

All three monitors are small: no bigger than a shoe box. Each one measures a specific property that provides a snapshot of the air quality aboard the station. Researchers will analyze the monitors based on weight, functionality, and ability to accurately measure and identify small concentrations of particles in the air.
The research team will receive data from the space station every two weeks. While those monitors are orbiting Earth, Fortenberry will have three matching monitors at Glenn. Engineers will compare functionality and results from the monitors used in space to those on the ground to verify they are working as expected in microgravity. Additional ground testing will involve dust simulants and smoke.
Air quality monitors like the ones NASA is testing also have Earth-based applications. The monitors are used to investigate smoke plumes from wildfires, haze from urban pollution, indoor pollution from activities like cooking and cleaning, and how virus-containing droplets spread within an enclosed space.
Results from the investigation will help NASA evaluate which monitors could accompany astronauts to the Moon and eventually Mars. NASA will allow the manufacturers to review results and ensure the monitors work as efficiently and effectively as possible. Testing aboard the space station could help companies investigate pollution problems here on Earth and pave the way for future missions to the Red Planet.

NASA commercial resupply missions to the International Space Station deliver scientific investigations in the areas of biology and biotechnology, Earth and space science, physical sciences, and technology development and demonstrations. Cargo resupply from U.S. companies ensures a national capability to deliver scientific research to the space station, significantly increasing NASA’s ability to conduct new investigations aboard humanity’s laboratory in space.
