Preparations for Next Moonwalk Simulations Underway (and Underwater)

NASA’s Stennis Space Center near Bay St. Louis, Mississippi, is helping the Artemis Generation learn how to power space dreams with an interactive exhibit at INFINITY Science Center.

The engine test simulator exhibit at the official visitor center of NASA Stennis provides the chance to experience the thrill of being a NASA test engineer by guiding an RS-25 engine through a simulated hot fire test.

“It is an exhilarating opportunity to feel what it is like to be a NASA engineer, responsible for making sure the engine is safely tested for launch,” said Chris Barnett-Woods, a NASA engineer that helped develop the software for the exhibit.

Sitting at a console mirroring the actual NASA Stennis Test Control Center, users are immersed in the complex process of engine testing. The exhibit uses cutting-edge software and visual displays to teach participants how to manage liquid oxygen and liquid hydrogen propellants, and other essential elements during a hot fire.

Users follow step-by-step instructions that include pressing buttons, managing propellant tanks, and even closing the flare stack, just as real engineers do at NASA Stennis. Once the test is complete, they are congratulated for successfully conducting their own rocket engine hot fire.

The interactive exhibit is not just about pushing buttons. It is packed with interesting facts about the RS-25 engine, which helps power NASA’s Artemis missions as the agency explores secrets of the universe for the benefit of all. Visitors also can view real hot fires conducted at NASA Stennis from multiple angles, deepening their understanding of rocket propulsion testing and NASA’s journey back to the Moon and beyond.

NASA is currently preparing for the Artemis II mission, the first crewed flight test of the agency’s powerful SLS (Space Launch System) rocket and the Orion spacecraft around the Moon.

The first four Artemis missions are using modified space shuttle main engines tested at NASA Stennis. The center also achieved a testing milestone last April for engines to power future Artemis missions. For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power NASA’s SLS rocket, producing more than 8.8 million pounds of total combined thrust at liftoff.

The revitalized exhibit, previously used when the visitor center was located onsite, represents a collaborative effort. It started as an intern project in the summer of 2023 before evolving into a full-scale experience. Engineers built on the initial concept, integrating carpentry, audio, and video to create the seamless experience to educate and inspire.

The best part might be that visitors to INFINITY Science Center can repeat the simulation as many times as they like, gaining confidence and learning more with each attempt.

“This exhibit was a favorite in the past, and with its new upgrades, the engine test simulator is poised to capture the imaginations of the Artemis Generation at INFINITY Science Center,” said NASA Public Affairs Specialist Samone Wilson. “This is one exhibit you will not want to miss.” INFINITY Science Center is located at 1 Discovery Circle, Pearlington, Mississippi.

      NASA Supports Wildland Fire Technology Demonstration
      By NASA

      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.

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.International Met Systems/Alana Dachtler In addition to the Alta X flights beginning March 25, NASA Armstrong’s B200 King Air will fly over actively burning fires at an altitude of about 6,500 feet. 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.

      By NASA
      NASA astronaut Christopher Williams poses for a portrait at NASA’s Johnson Space Center in Houston, Texas.Credit: NASA NASA astronaut Chris Williams will embark on his first mission to the International Space Station, serving as a flight engineer and Expedition 74 crew member.
      Williams will launch aboard the Roscosmos Soyuz MS-28 spacecraft in November, accompanied by Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev. After launching from the Baikonur Cosmodrome in Kazakhstan, the trio will spend approximately eight months aboard the orbiting laboratory.
      During his expedition, Williams will conduct scientific investigations and technology demonstrations that help prepare humans for future space missions and benefit humanity.
      Selected as a NASA astronaut in 2021, Williams graduated with the 23rd astronaut class in 2024. He began training for his first space station flight assignment immediately after completing initial astronaut candidate training.
      Williams was born in New York City, and considers Potomac, Maryland, his hometown. He holds a bachelor’s degree in Physics from Stanford University in California and a doctorate in Physics from the Massachusetts Institute of Technology in Cambridge, where his research focused on astrophysics. Williams completed Medical Physics Residency training at Harvard Medical School in Boston. He was working as a clinical physicist and researcher at the Brigham and Women’s Hospital in Boston when he was selected as an astronaut.
      For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is able to more fully focus its resources on deep space missions to the Moon and Mars.

      La NASA aumenta su eficiencia con un piso modificado para el avión X-66

      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.
      Eric Garza, técnico de ingeniería en el Taller de Fabricación Experimental del Centro de Investigación de Vuelo Armstrong de la NASA en Edwards, California, observa cómo una máquina de madera corta agujeros para las tablas del piso temporal el 26 de agosto de 2024. El piso fue diseñado para el avión de demostración experimental X-66. NASA/Steve Freeman Artículo Traducido por: Priscila Valdez
