3 Min Read NASA Engineers Simulate Lunar Lighting for Artemis III Moon Landing
Better understanding the lunar lighting environment will help NASA prepare astronauts for the harsh environment Artemis III Moonwalkers will experience on their mission. NASA’s Artemis III mission will build on earlier test flights and add new capabilities with the human landing system and advanced spacesuits to send the first astronauts to explore the lunar South Pole and prepare humanity to go to Mars.
Using high-intensity lighting and low-fidelity mock-ups of a lunar lander, lunar surface, and lunar rocks, NASA engineers are simulating the Moon’s environment at the Flat Floor Facility to study and experience the extreme lighting condition. The facility is located at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
NASA engineers inside the Flat Floor Facility at Marshall Space Flight Center in Huntsville, Alabama, mimic lander inspection and assessment tasks future Artemis astronauts may do during Artemis III. Lights are positioned at a low angle to replicate the strong shadows that are cast across the lunar South Pole. NASA/Charles Beason “The goal is really to understand how shadows will affect lander visual inspection and assessment efforts throughout a future crewed mission,” said Emma Jaynes, test engineer at the facility. “Because the Flat Floor Facility is similar to an inverted air hockey table, NASA and our industry partners can rearrange large, heavy structures with ease – and inspect the shadows’ effects from multiple angles, helping to ensure mission success and astronaut safety for Artemis III.”
Data and analysis from testing at NASA are improving models Artemis astronauts will use in preparation for lander and surface operations on the Moon during Artemis III. The testing also is helping cross-agency teams evaluate various tools astronauts may use.
The 86-foot-long by 44-foot-wide facility at NASA is one of the largest, flattest, and most stable air-bearing floors in the world, allowing objects to move across the floor without friction on a cushion of air.
Test teams use large, 12-kilowatt and 6-kilowatt lights to replicate the low-angle, high contrast conditions of the lunar South Pole. Large swaths of fabric are placed on top of the epoxy floor to imitate the reflective properties of lunar regolith. All the mock-ups are placed on air bearings, allowing engineers to easily move and situate structures on the floor.
The Flat Floor Facility is an air-bearing floor, providing full-scale simulation capabilities for lunar surface systems by simulating zero gravity in two dimensions. Wearing low-fidelity materials, test engineers can understand how the extreme lighting of the Moon’s South Pole could affect surface operations during Artemis III. NASA/Charles Beason “The Sun is at a permanent low angle at the South Pole of the Moon, meaning astronauts will experience high contrasts between the lit and shadowed regions,” Jaynes said. “The color white can become blinding in direct sunlight, while the shadows behind a rock could stretch for feet and ones behind a lander could extend for miles.”
The laboratory is large enough for people to walk around and experience this phenomenon with the naked eye, adding insight to what NASA calls ‘human in-the-loop testing.
NASA is working with SpaceX to develop the company’s Starship Human Landing System to safely send Artemis astronauts to the Moon’s surface and back to lunar orbit for Artemis III.
Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.

A NASA-sponsored team is creating a new approach to measure magnetic fields by developing a new system that can both take scientific measurements and provide spacecraft attitude control functions. This new system is small, lightweight, and can be accommodated onboard the spacecraft, eliminating the need for the boom structure that is typically required to measure Earth’s magnetic field, thus allowing smaller, lower-cost spacecraft to take these measurements. In fact, this new system could not only enable small spacecraft to measure the magnetic field, it could replace the standard attitude control systems in future spacecraft that orbit Earth, allowing them to provide the important global measurements that enable us to understand how Earth’s magnetic field protects us from dangerous solar particles.

Solar storms drive space weather that threatens our many assets in space and can also disrupt Earth’s upper atmosphere impacting our communications and power grids. Thankfully, the Earth’s magnetic field protects us and funnels much of that energy into the north and south poles creating aurorae. The aurorae are a beautiful display of the electromagnetic energy and currents that flow throughout the Earth’s space environment. They often have small-scale magnetic features that affect the total energy flowing through the system. Observing these small features requires multiple simultaneous observations over a broad range of spatial and temporal scales, which can be accomplished by constellations of small spacecraft.
To enable such constellations, NASA is developing an innovative hybrid magnetometer that makes both direct current (DC) and alternating current (AC) magnetic measurements and is embedded in the spacecraft’s attitude determination and control system (ADCS)—the system that enables the satellite to know and control where it is pointing. High-performance, low SWAP+C (low-size, weight and power + cost) instruments are required, as is the ability to manufacture and test large numbers of these instruments within a typical flight build schedule. Future commercial or scientific satellites could use these small, lightweight embedded hybrid magnetometers to take the types of measurements that will expand our understanding of space weather and how Earth’s magnetic field responds to solar storms
It is typically not possible to take research-quality DC and AC magnetic measurements using sensors within an ADCS since the ADCS is inside the spacecraft and near contaminating sources of magnetic noise such as magnetic torque rods—the electromagnets that generate a magnetic field and push against the Earth’s magnetic field to control the orientation of a spacecraft. Previous missions that have flown both DC and AC magnetometers placed them on long booms pointing in opposite directions from the satellite to keep the sensors as far from the spacecraft and each other as possible. In addition, the typical magnetometer used by an ADCS to measure the orientation of the spacecraft with respect to the geomagnetic field does not sample fast enough to measure the high-frequency signals needed to make magnetic field observations.
A NASA-sponsored team at the University of Michigan is developing a new hybrid magnetometer and attitude determination and control system (HyMag-ADCS) that is a low-SWAP single package that can be integrated into a spacecraft without booms. HyMag-ADCS consists of a three-axis search coil AC magnetometer and a three-axis Quad-Mag DC magnetometer. The Quad-Mag DC magnetometer uses machine learning to enable boomless DC magnetometery, and the hybrid search-coil AC magnetometer includes attitude determination torque rods to enable the single 1U volume (103 cm) system to perform ADCS functions as well as collect science measurements.

Quad-Mag Hardware: The Quad-Mag DC magnetometer consists of four magneto-inductive magnetometers and a space-qualified micro-controller mounted on a single CubeSat form factor (10 x 10 cm) printed circuit board. These two types of devices are commercially available. Combining multiple sensors on a single board increases the instrument’s sensitivity by a factor of two compared to using a single sensor. In addition, the distributed sensors enable noise identification on small satellites, providing the science-grade magnetometer sensing that is key for both magnetic field measurements and attitude determination. The same type of magnetometer is part of the NASA Artemis Lunar Gateway Heliophysics Environmental and Radiation Measurement Experiment Suite (HERMES) Noisy Environment Magnetometer in a Small Integrated System (NEMISIS) magnetometer scheduled for launch in early 2027.
Dual-use Electromagnetic Rods: The HyMag-ADCS team is using search coil electronics and torque rod electronics that were developed for other efforts in a new way. Use of these two electronics systems enables the electromagnetic rods in the HyMag-ADCS system to be used in two different ways—as torque rods for attitude determination and as search coils to make scientific measurements. The search coil electronics were designed for ground-based measurements to observe ultra-low frequency signals up to a few kHz that are generated by magnetic beacons for indoor localization. The torque rod electronics were designed for use on CubeSats and have flown on several University of Michigan CubeSats (e.g., CubeSat-investigating Atmospheric Density Response to Extreme driving [CADRE]). The HyMag-ADCS concept is to use the torque rod electronics as needed for attitude control and use the search coil electronics the rest of the time to make scientific AC magnetic field measurements.
Machine Learning Algorithms for Spacecraft Noise Identification: Applying machine learning to these distributed sensors will autonomously remove noise generated by the spacecraft. The team is developing a powerful Unsupervised Blind Source Separation (UBSS) algorithm and a new method called Wavelet Adaptive Interference Cancellation for Underdetermined Platforms (WAIC-UP) to perform this task, and this method has already been demonstrated in simulation and the lab.
The HyMag-ADCS system is early in its development stage, and a complete engineering design unit is under development. The project is being completed primarily with undergraduate and graduate students, providing hands-on experiential training for upcoming scientists and engineers.

Heyman Service to America Medals, also known as the Sammies, recognizing outstanding federal employees who are addressing many of our country’s greatest challenges.
Rich Burns of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and John Blevins of Marshall Space Flight Center in Huntsville, Alabama, were selected out of 350 nominees and are among 23 individuals and teams honored for their achievements as federal employees. They will be recognized at a ceremony in Washington on Tuesday, June 17, that also will be live streamed on the Sammies website. The honorees will be commended via videos and presenter remarks and receive medals for their achievements.
Named after the founder of the Partnership for Public Service, the 2025 Service to America Medals awards celebrate federal employees who provided critical public services and made outstanding contributions to the health, safety, and national security of our country.
“Rich and John exemplify the spirit of exploration and service that defines NASA and our nation’s civil servants,” said acting NASA Administrator Janet Petro. “Their leadership, ingenuity, and dedication have not only advanced America’s space program but also inspired the next generation of innovators. We are proud to see their achievements recognized among the very best of federal service.”
Richard Burns, project manager for the Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer (OSIRIS-REx) at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and honoree of the 2025 Samuel J. Heyman Service to America MedalsCredit: NASA Burns was the project manager of the Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer (OSIRIS-REx) mission to collect a sample from an asteroid and oversaw operations from the developmental stage to the successful landing of the spacecraft’s Sample Return Capsule.
The mission launched on Sept. 18, 2016, and after a nearly four-year journey, the OSIRIS-REx spacecraft successfully collected a sample from the asteroid Bennu on Oct. 20, 2020, which returned to Earth on Sept. 24, 2023, providing scientists with 120 grams of pristine material to study, the largest amount ever collected from an asteroid. Working to solidify OSIRIS-REx as a success, Burns set up multiple partnerships and communicated frequently with scientists, large and small businesses, NASA centers, and others to ensure the mission’s vision was carried out though each phase.
During the mission, Burns had to handle unique challenges that required adapting to new situations. These included improving flight software to help the spacecraft avoid hazardous parts of Bennu’s rocky surface and working with NASA leaders to find a way to best protect the sample collected from Bennu after a large stone propped the collection canister open. Finally, when the sample was set to return to Earth, Burns worked extensively with NASA and military partners to prepare for the landing, focusing on the safety of the public along with the integrity of the sample to ensure the final part of the mission was a success.
Burns helped OSIRIS-REx exceed its objectives all while under the original budget, allowing NASA to share a portion of the sample with more than 80 research projects and make new discoveries about the possible origins of life on our planet. The spacecraft, now known as Origins, Spectral Interpretation, Resource Identification and Security – Apophis Explorer, is scheduled to rendezvous with the asteroid Apophis in 2029.
“It’s humbling to accept an award based on the achievements of the amazingly talented, dedicated, and innovative OSIRIS-REx team,” Burns said. “I consider myself privileged to be counted among a team of true explorers who let no obstacle stand in the way of discovery.”

This included calculating structural needs, thermal analyses of the effects, and studies of vibrations, acoustics, propulsion integration, among other work.
Artemis I, the first test flight of the SLS rocket, successfully launched from NASA’s Kennedy Space Center in Florida on Nov. 16, 2022. In the time leading up to and during launch, Blevins led the team integrating the hardware for the mission working to address unexpected events while SLS was on the pad prior to launch. This included significant lightning storms and two hurricanes impacting Kennedy Space Center in Florida.
Blevins built a working coalition of engineering teams across the agency that previously did not exist. His ability to forge strong relationships on the various teams across the agency allowed for the successful launch of Artemis I. He continues to lead the engineering team behind SLS as they prepare for Artemis II, the second flight of SLS and the first crewed lunar mission of the 21st century.
“This is a reflection on the hard work and dedication of the entire Artemis Team,” Blevins said. “I am working with an incredibly competent, dedicated team agencywide that goes above and beyond to promote the space exploration goals of our nation. I am honored to accept the award on their behalf.”
