Preparations for Next Moonwalk Simulations Underway (and Underwater)
Drones were a key part of testing new technology in support of a prescribed burn in Geneva State Forest, which is about 100 miles south of Montgomery, Alabama. The effort is part of the agency’s multi-year FireSense project, which is aimed at testing technologies that could eventually serve the U.S. Forest Service as well as local, state, and other federal wildland fire agencies. From left are Tim Wallace and Michael Filicchia of the Desert Research Institute in Nevada; Derek Abramson, Justin Hall, and Alexander Jaffe of NASA’s Armstrong Flight Research Center in Edwards California; and Alana Dachtler of International Met Systems of Kentwood, Michigan.NASA/Jackie Shuman Advancements in NASA’s airborne technology have made it possible to gather localized wind data and assess its impacts on smoke and fire behavior. This information could improve wildland fire decision making and enable operational agencies to better allocate firefighters and resources. A small team from NASA’s Armstrong Flight Research Center in Edwards, California, is demonstrating how some of these technologies work.
Two instruments from NASA’s Langley Research Center in Hampton, Virginia – a sensor gathering 3D wind data and a radiosonde that measures temperature, barometric pressure, and humidity data – were installed on NASA Armstrong’s Alta X drone for a prescribed burn in Geneva State Forest, which is about 100 miles south of Montgomery, Alabama. The effort is part of the agency’s multi-year FireSense project, which is aimed at testing technologies that could eventually serve the U.S. Forest Service as well as local, state, and other federal wildland fire agencies.
“The objectives for the Alta X portion of the multi-agency prescribed burn include a technical demonstration for wildland fire practitioners, and data collection at various altitudes for the Alabama Forestry Commission operations,” said Jennifer Fowler, FireSense project manager. “Information gathered at the different altitudes is essential to monitor the variables for a prescribed burn.”
Those variables include the mixing height, which is the extent or depth to which smoke will be dispersed, a metric Fowler said is difficult to predict. Humidity must also be above 30% for a prescribed burn. The technology to collect these measurements locally is not readily available in wildland fire operations, making the Alta X and its instruments key in the demonstration of prescribed burn technology.

Sensors onboard other aircraft supporting the mission will fly at lower altitudes during the fire, and at higher altitudes before and after the fire for required data collection. The multi-agency mission will provide data to confirm and adjust the prescribed burn forecast model.
Small, uncrewed aircraft system pilots from NASA Armstrong completed final preparations to travel to Alabama and set up for the research flights. The team – including Derek Abramson, chief engineer for the subscale flight research laboratory; Justin Hall, NASA Armstrong chief pilot of small, uncrewed aircraft systems; and Alexander Jaffe, a drone pilot – will set up, fly, observe airborne operations, all while keeping additional aircraft batteries charged. The launch and recovery of the Alta X is manual, the mission profile is flown autonomously to guarantee the same conditions for data collection.
“The flight profile is vertical – straight up and straight back down from the surface to about 3,000 feet altitude,” Abramson said. “We will characterize the mixing height and changes in moisture, mapping out how they both change throughout the day in connection with the burn.”
In August 2024, a team of NASA researchers used the NASA Langley Alta X and weather instruments in Missoula, Montana, for a FireSense project drone technology demonstration. These instruments were used to generate localized forecasting that provides precise and sustainable meteorological data to predict fire behavior and smoke impacts.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Eric Garza, técnico de ingeniería en el Taller de Fabricación Experimental del Centro de Investigación de Vuelos Armstrong de la NASA en Edwards, California, corta madera contrachapada a medida para las tablas del piso temporal del avión demostrador experimental X-66 el 26 de agosto de 2024.NASA/Steve Freeman Lee esta historia en español aquí.
La NASA diseño unas tablas de piso temporales para el avión MD-90, que se utilizaran mientras el avión se transforma en el demostrador experimental X-66. Estas tablas de piso protegerán el piso original y agilizarán el proceso de modificación.
En apoyo al proyecto Demostrador de Vuelo Sostenible de la agencia, un pequeño equipo del Taller de Fabricación Experimental del Centro de Investigación de Vuelos Armstrong de la NASA en Edwards, California, construyó tablas de piso temporales para ahorrarle tiempo y recursos al proyecto. La retirada e instalación repetidas del piso original durante el proceso de modificación requería mucho tiempo. El uso de paneles temporales también garantiza la protección de las tablas del piso original y su aptitud para el vuelo cuando se finalicen las modificaciones y se vuelva a instalar el piso original.
“La tarea de crear las tablas de piso temporales para el MD-90 implica un proceso meticuloso dirigido a facilitar las modificaciones, manteniendo la seguridad y la eficacia. La necesidad de estas tablas de piso temporales surge del detallado procedimiento necesario para retirar y reinstalar los pisos originales del fabricante (OEM, por su acrónimo inglés),” explica Jason Nelson, jefe de fabricación experimental. Él es uno de los dos miembros del equipo de fabricación – un técnico de ingeniería y un inspector – que fabrica acerca de 50 tablas de piso temporales, con dimensiones que varían entre 20 pulgadas por 36 pulgadas y 42 pulgadas por 75 pulgadas.
Una máquina de madera corta agujeros precisos en madera contrachapada para las tablas del piso temporal el 26 de agosto de 2024, en el Taller de Fabricación Experimental del Centro de Investigación de Vuelo Armstrong de la NASA en Edwards, California. El piso fue diseñado para el avión de demonstración experimental X-66. NASA/Steve Freeman Nelson continuó, “Como estas tablas OEM se quitarán y volverán a instalar varias veces para acomodar las modificaciones necesarias, las tablas temporales ahorrarán al equipo tiempo y recursos valiosos. También proporcionarán el mismo nivel de seguridad y resistencia que las tablas OEM, garantizando que el proceso se desarrolle sin problemas y sin comprometer la calidad.”
El diseño y la creación de prototipos del piso fue un proceso meticuloso, pero la solución temporal desempeña un papel crucial en la optimización del tiempo y los recursos en los esfuerzos de la NASA por avanzar en la seguridad y la eficiencia de los viajes aéreos. El proyecto Demostrador de Vuelo Sostenible de la agencia busca informar la próxima generación de aviones pasajeros de un solo pasillo, que son las aeronaves más comunes de aviación comercial de todo el mundo. La NASA se asoció con Boeing para desarrollar el avión de demostración experimental X-66. El Taller de Fabricación Experimental de Armstrong de la NASA lleva a cabo modificaciones y trabajos de reparación en aeronaves, que van desde la creación de algo tan pequeño como un soporte de aluminio hasta la modificación de la estructura principal de las alas, las costillas del fuselaje, las superficies de control y otras tareas de apoyo a las misiones.

5 Min Read NASA Langley’s Legacy of Landing
The first image of the Moon taken by the cameras on the Lunar Orbiter in 1966. Credits: NASA Landing safely on the surface of another planetary body, like the Moon or Mars, is one of the most important milestones of any given space mission. From the very beginning, NASA’s Langley Research Center has been at the heart of the entry, descent and landing (EDL) research that enables our exploration. Today, NASA Langley’s legacy of landing continues at the forefront of present day lunar missions and as NASA prepares for future travel to more distant worlds.
Project Mercury: 1958
Project Mercury was the United States’ first human-in-space program, led by NASA’s Space Task Group located at NASA Langley. There were five major programs of study and experimentation.
An airdrop study that helped us understand the characteristics of the Mercury capsule as it returned to Earth. A group of study focused on the escape systems, ultimately becoming known as the launch abort system. Exhaustive wind-tunnel studies of the blunt-nosed capsule design and its aerodynamic stability at various altitudes and speeds and angles of reentry, all with a focus on making the capsule safe and stable. A study on the problem of landing impact, resulting in the development of absorption systems that minimized the shock of impact to the capsule’s pilot. Studies into the use of drogue parachutes and their characteristics at high altitudes and speeds, ensuring that they would be able to stabilize and slow the capsule’s descent for a safe landing. All of this research went on to inform the subsequent Gemini and Apollo programs. All of this research went on to inform the subsequent Gemini and Apollo programs.
Apollo Program: 1962
In 1961, President John F. Kennedy committed to putting Americans on the surface of the Moon and shortly after that historic declaration, NASA’s Apollo program was born. In the years that followed, the original team of NASA astronauts completed their basic training at NASA Langley’s Lunar Landing Research Facility (LLRF). When Apollo 11 successfully landed the first humans on the Moon in 1969, NASA Langley had played a pivotal role in the monumental success.
Lunar Orbiter: 1966
The Lunar Orbiter missions launched with the purpose of mapping the lunar surface and identifying potential landing sites ahead of the Apollo landings. From 1966 to 1967, the five successful Lunar Orbiter missions, led and managed by Langley Research Center, resulted in 99% of the moon photographed and a suitable site selected for the upcoming human landings.
Viking: 1976
After the success of Apollo, NASA set its sights further across the solar system to Mars. Two Viking missions aimed to successfully place landers on the Red Planet and capture high resolution images of the Martian surfaces, assisting in the search for life. Langley Research Center was chosen to lead this inaugural Mars mission and went on to play key roles in the missions to Mars that followed.
HIAD: 2009 – Present
Successful landings on Mars led to more ambitious dreams of landing larger payloads, including those that could support future human exploration. In order to land those payloads safely, a new style of heat shield would be needed. Hypersonic Inflatable Aerodynamic Decelerator (HIAD) technology was positioned as an answer to the payload problem, enabling missions to use inflatable heat shields to slow down and protect a payload as it enters a planet’s atmosphere at hypersonic speeds.
IRVE – 2009-2012
Two successful Inflatable Reentry Vehicle Experiments (IRVE) proved the capability of inflatable heat shield technology and opened the door for larger iterations.
LOFTID – 2022
The Low Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) followed in the footsteps of its predecessor IRVE with a larger aeroshell that could be deployed to a scale much larger than the shroud. The 2022 successful test of this technology further proved the capability of HIAD technology.
MEDLI 1 and 2: 2012 & 2020
As a part of the Mars Science Laboratory (MSL) mission, NASA Langley’s Mars Entry, Descent and Landing Instrument (MEDLI) was designed to gather data from the MSL entry vehicle’s heatshield during its entry and descent to the surface of Mars. MEDLI2 expanded on that groundbreaking data during the Mars 2020 mission which safely landed the Perseverance rover after successfully entering the planet’s arid atmosphere, and enabling improvements on the design for future entry systems.
Curiosity Rover
Curiosity was the largest and most capable rover ever sent to Mars when it launched in 2011. Leading up the mission, Langley engineers performed millions of simulations of the entry, descent and landing phase — or the so-called “Seven Minutes of Terror” — that determines success or failure. Curiosity continues to look for signs that Mars once was – or still is – a habitable place for life as we know it.
CLPS: 2023 – Present
The Commercial Lunar Payload Services initiative takes the Artemis mission further by working with commercial partners to advance the technology needed to return humans to the Moon and enable humanity to explore Mars.
NDL
Navigation Doppler Lidar (NDL) technology, developed at Langley Research Center, uses lasers to assist spacecraft in identifying safe locations to land. In 2024, NDL flew on the Intuitive Machines’ uncrewed Nova-C lander, with its laser instruments designed to measure velocity and altitude to within a few feet. While NASA planetary landers have traditionally relied on radar and used radio waves, NDL technology has proven more accurate and less heavy, both major benefits for cost and space savings as we continue to pursue planetary missions.
SCALPSS
Like Lunar Orbiter and the Viking missions before it, Stereo Cameras for Lunar Plume Surface Studies (SCALPSS) set out to better understand the surface of another celestial body. These cameras affixed to the bottom of a lunar lander focus on the interaction between the lander’s rocket plumes and the lunar surface. The SCALPSS 1.1 instrument captured first-of-its-kind imagery as the engine plumes of Firefly’s Blue Ghost lander reached the Moon’s surface. These images will serve as key pieces of data as trips to the Moon increase in the coming years.

An electron microscopy images of multicellular magnetotactic bacteria that featured on the covers of the 2022 edition of The ISME Journal. The image was produced by Schaible and co-workers under the group’s NASA awards.Roland Hatzenpichler / Montana State University In a recent study, NASA-supported researchers gained new insight into the lives of bacteria that survive by grouping together as if they were a multi-cellular organism. The organisms in the study are the only bacteria known to do this in this way, and studying them could help astrobiologists explain important steps in the evolution of life on Earth.
The organisms in the study are known as ‘multicellular magnetotactic bacteria,’ or MMB. Being magnetotactic means that MMB are part of a select group of bacteria that orient their movement based on Earth’s magnetic field using tiny ‘compass needles’ in their cells. As if that wasn’t special enough, MMB also live bunched up in collections of cells that are considered by some scientists to exhibit ‘obligate’ multicellularity, which is the trait the new study is focused on.
In biology, obligate means that an organism requires something for survival. In this case, it means that single cells of MMB cannot survive on their own. Instead, cells live as a consortium of multiple cells that behave in many ways like a single multicellular organism. This requirement to live together means that when MMB reproduce, they do so by replicating all the cells in the consortium at once, doubling the total number of cells. This large group of cells then splits into two identical consortia.
Electron microscopy image and cartoon of a MMB consortium, highlighting its characteristics features that includes a hollow space at the center of the cell consortium.George Shaible et al. PLOS Biology 2024 MMB are the only example of bacteria that are known to live like this. Many other bacteria clump together as simple aggregates of single cells. For instance, cyanobacteria clump together in colonies and form structures like stromatolites or biofilms that are visible to the naked eye. However, unlike MMB, these cyanobacteria can also survive as single, individual cells.
In the new study, scientists have revealed even more complexity in the relationships between MMB cells. First, contrary to long-held assumptions, individual cells within MMB consortia are not genetically identical, they differ slightly in their genetic blueprint. Further, cells within a consortium exhibit different and complementary behavior in terms of their metabolism. Each cell in an MMB consortium has a role that contributes to the survival of the entire group. This behavior is similar to how individual cells within multicellular organisms behave. For example, human bodies are made up of tens of trillions of cells. These cells differentiate into specific cell types with different functions. Bone cells are not the same as blood cells. Fat cells that store energy are different from the nerve cells that store and transmit information. Each cell has a role to play, and together they make up a single living body.
The proposed life cycle of multicellular magnetotactic bacteria (MMB). Credit: George ShcaibleGeorge Schaible The evolution of multicellularity is one of the major transitions in the history life on our planet and had profound effects on Earth’s biosphere. In the wake of its appearance, life developed novel strategies for survival that led to entirely new ecosystems. As the only example of bacteria that exhibit obligate multicellularity, MMB provide an important example of possible mechanisms behind this profound step in life’s evolutionary history on Earth.
The study, “Multicellular magnetotactic bacteria are genetically heterogeneous consortia with metabolically differentiated cells,” was published in PLOS Biology. The work was supported through the NASA Exobiology program and the Future Investigators in NASA Earth and Space Science and Technology (FINESST) program.
