NASA’s Electrodynamic Dust Shield (EDS) successfully demonstrated its ability to remove regolith, or lunar dust and dirt, from its various surfaces on the Moon during Firefly Aerospace’s Blue Ghost Mission 1, which concluded on March 16. Lunar dust is extremely abrasive and electrostatic, which means it clings to anything that carries a charge. It can damage everything from spacesuits and hardware to human lungs, making lunar dust one of the most challenging features of living and working on the lunar surface. The EDS technology uses electrodynamic forces to lift and remove the lunar dust from its surfaces. The first image showcases the glass and thermal radiator surfaces, coated in a layer of regolith. As you slide to the left, the photo reveals the results after EDS activation. Dust was removed from both surfaces, proving the technology’s effectiveness in mitigating dust accumulation.
This milestone marks a significant step toward sustaining long-term lunar and interplanetary operations by reducing dust-related hazards to a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. The EDS technology is paving the way for future dust mitigation solutions, supporting NASA’s Artemis campaign and beyond. NASA’s Electrodynamic Dust Shield was developed at Kennedy Space Center in Florida with funding from NASA’s Game Changing Development Program, managed by the agency’s Space Technology Mission Directorate.

En esta ilustración se muestra al telescopio NICER (a la izquierda) montado en la Estación Espacial Internacional y al telescopio LEXI (a la derecha) sujeto a la parte superior del módulo Blue Ghost de Firefly Aerospace.NASA/Firefly Aerospace La Estación Espacial Internacional sustenta una amplia gama de actividades científicas, desde la observación de nuestro universo hasta el logro de avances en investigaciones médicas, y es un campo de pruebas activo en la tecnología para futuras misiones de exploración en la Luna y más allá. La misión Blue Ghost 1 de Firefly Aerospace aterrizó en la Luna el 2 de marzo de 2025, dando inicio a las operaciones científicas y tecnológicas en su superficie, las cuales incluyen tres experimentos que fueron evaluados o habilitados con las investigaciones de la estación espacial. Estos proyectos están ayudando a los científicos a estudiar la meteorología espacial, la navegación, y el desempeño de las computadoras en el espacio, los cuales son conocimientos cruciales para futuras misiones a la Luna.
Uno de los experimentos, el Generador de imágenes de rayos X heliosférico para el entorno lunar (LEXI, por sus siglas en inglés), es un pequeño telescopio diseñado para estudiar el entorno magnético de la Tierra y su interacción con el viento solar. Al igual que el telescopio Explorador de la composición interior de las estrellas de neutrones (NICER, por sus siglas en inglés) que está montado fuera de la estación espacial, LEXI observa las fuentes de rayos X. LEXI y NICER observaron la misma estrella en rayos X para calibrar el instrumento de LEXI y analizar mejor los rayos X emitidos desde la atmósfera superior de la Tierra, que es el objetivo principal de LEXI. El estudio de LEXI sobre la interacción entre el viento solar y la magnetosfera protectora de la Tierra podría ayudar a los investigadores a desarrollar métodos para salvaguardar la futura infraestructura espacial y comprender cómo responde esta frontera a las condiciones meteorológicas en el espacio.
Otros investigadores enviaron a la Luna el Sistema informático tolerante a la radiación (RadPC, por sus siglas en inglés) para realizar pruebas sobre cómo las computadoras pueden recuperarse de fallas relacionadas con la radiación. Antes de que RadPC volara a bordo de Blue Ghost, los investigadores hicieron pruebas con una computadora tolerante a la radiación en la estación espacial y desarrollaron un algoritmo para detectar posibles desperfectos en el hardware y evitar fallas críticas. RadPC tiene como objetivo demostrar la resistencia de las computadoras en el entorno de radiación de la Luna. La computadora puede medir su propia salud en tiempo real, y RadPC puede identificar un punto defectuoso y repararlo en segundo plano, según sea necesario. Los conocimientos adquiridos con esta investigación podrían mejorar el hardware informático para futuras misiones en el espacio profundo.
Además, el Experimento del receptor lunar de GNSS (LuGRE, por sus siglas en inglés) situado en la superficie de la Luna ha recibido oficialmente una señal del Sistema Global de Navegación por Satélite (GNSS, por sus siglas en inglés) a la distancia más lejana de la Tierra. Estas son las mismas señales para la navegación que se utilizan en la Tierra en todo, desde teléfonos inteligentes hasta aviones. A bordo de la Estación Espacial Internacional, el Banco de Pruebas de Navegación y Comunicaciones (NAVCOM, por sus siglas en inglés) ha llevado a cabo pruebas de un sistema de respaldo para el GNSS de la Tierra utilizando estaciones terrestres como un método alternativo para la navegación lunar cuando las señales del GNSS puedan tener limitaciones. Unir los sistemas existentes con soluciones emergentes específicas para la navegación lunar podría ayudar a dar forma al modo en que las naves espaciales navegan por la Luna en futuras misiones.
La Estación Espacial Internacional funciona como un importante banco de pruebas para las investigaciones que se llevan a cabo en misiones como Blue Ghost y continúa sentando las bases para las tecnologías del futuro.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s LRO (Lunar Reconnaissance Orbiter) imaged Firefly Aerospace’s Blue Ghost Mission 1 lunar lander on the Moon’s surface the afternoon of March 2, not quite 10 hours after the spacecraft landed.
Firefly Aerospace’s Blue Ghost Mission 1 lunar lander, which appears in this image from NASA’s Lunar Reconnaissance Orbiter as a bright pixel casting a shadow in the middle of the white box, reached the surface of the Moon on March 2 at 3:34 a.m. EST.NASA/Goddard/Arizona State University The delivery is part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. This is the first CLPS delivery for Firefly, and their first Moon landing.
LRO is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the Science Mission Directorate at NASA Headquarters in Washington. Launched on June 18, 2009, LRO has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the Moon. NASA is returning to the Moon with commercial and international partners to expand human presence in space and bring back new knowledge and opportunities.

If you design a new tool for use on Earth, it is easy to test and practice using that tool in its intended environment. But what if that tool is destined for lunar orbit or will be used by astronauts on the surface of the Moon?
NASA’s Simulation and Graphics Branch can help with that. Based at Johnson Space Center in Houston, the branch’s high-fidelity, real-time graphical simulations support in-depth engineering analyses and crew training, ensuring the safety, efficiency, and success of complex space endeavors before execution. The team manages multiple facilities that provide these simulations, including the Prototype Immersive Technologies (PIT) Lab, Virtual Reality Training Lab, and the Systems Engineering Simulator (SES).
Lee Bingham is an aerospace engineer on the simulation and graphics team. His work includes developing simulations and visualizations for the NASA Exploration Systems Simulations team and providing technical guidance on simulation and graphics integration for branch-managed facilities. He also leads the branch’s human-in-the-loop Test Sim and Graphics Team, the Digital Lunar Exploration Sites Unreal Simulation Tool (DUST), and the Lunar Surface Mixed-Reality with the Active Response Gravity Offload System (ARGOS) projects.
Lee Bingham demonstrates a spacewalk simulator for the Gateway lunar space station during NASA’s Tech Day on Capitol Hill in Washington, D.C. Image courtesy of Lee Bingham Bingham is particularly proud of his contributions to DUST, which provides a 3D visualization of the Moon’s South Pole and received Johnson’s Exceptional Software of the Year Award in 2024. “It was designed for use as an early reference to enable candidate vendors to perform initial studies of the lunar terrain and lighting in support of the Strategy and Architecture Office, human landing system, and the Extravehicular Activity and Human Surface Mobility Program,” Bingham explained. DUST has supported several human-in-the-loop studies for NASA. It has also been shared with external collaborators and made available to the public through the NASA Software Catalog.
Bingham has kept busy during his nearly nine years at Johnson and said learning to manage and balance support for multiple projects and customers was very challenging at first. “I would say ‘yes’ to pretty much anything anyone asked me to do and would end up burning myself out by working extra-long hours to meet milestones and deliverables,” he said. “It has been important to maintain a good work-life balance and avoid overcommitting myself while meeting demanding expectations.”
Lee Bingham tests the Lunar Surface Mixed Reality and Active Response Gravity Offload System trainer at Johnson Space Center. Image courtesy of Lee Bingham Bingham has also learned the importance of teamwork and collaboration. “You can’t be an expert at everything or do everything yourself,” he said. “Develop your skills, practice them regularly, and master them over time but be willing to ask for help and advice. And be sure to recognize and acknowledge your coworkers and teammates when they go above and beyond or achieve something remarkable.”
