3 Min Read NASA’s IMAP Arrives at NASA Marshall For Testing in XRCF
On March 18, NASA’s IMAP (Interstellar Mapping and Acceleration Probe) arrived at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for thermal vacuum testing at the X-ray and Cryogenic Facility, which simulates the harsh conditions of space.
The IMAP mission is a modern-day celestial cartographer that will map the solar system by studying the heliosphere, a giant bubble created by the Sun’s solar wind that surrounds our solar system and protects it from harmful interstellar radiation.

The IMAP mission will orbit the Sun at a location called Lagrange Point 1 (L1), which is about one million miles from Earth towards the Sun. From this location, IMAP can measure the local solar wind and scan the distant heliosphere without background from planets and their magnetic fields. The mission will use its suite of ten instruments to map the boundary of the heliosphere, analyze the composition of interstellar particles that make it through, and investigate how particles change as they move through the solar system.
Furthermore, IMAP will maintain a continuous broadcast of near real-time space weather data from five instruments aboard IMAP that will be used to test new space weather prediction models and improve our understanding of effects impacting our human exploration of space.
Team members from Marshall Space Flight Center in Huntsville, Alabama, install IMAP into the XRCF’s chamber dome before the start of the thermal vacuum test. NASA/Johns Hopkins APL/Princeton/Ed Whitman While inside the Marshall facility, the spacecraft will undergo dramatic temperature changes to simulate the environment during launch, on the journey toward the Sun, and at its final orbiting point. The testing facility has multiple capabilities including a large thermal vacuum chamber which simulates the harsh conditions of space such as extreme temperatures and the near-total absence of an atmosphere. Simulating these conditions before launch allow scientists and engineers to identify successes and potential failures in the design of the spacecraft.
Team members from Marshall Space Flight Center in Huntsville, Alabama work to close the chamber door of the XRCF for IMAP testing. The chamber is 20 feet in diameter and 60 feet long making it one of the largest across NASA. NASA/Johns Hopkins APL/Princeton/Ed Whitman “The X-ray and Cryogenic Facility was an ideal testing location for IMAP given the chamber’s size, availability, and ability to meet or exceed the required test parameters including strict contamination control, shroud temperature, and vacuum level,” said Jeff Kegley, chief of Marshall’s Science Test Branch.
The facility’s main chamber is 20 feet in diameter and 60 feet long, making it the 5th largest thermal vacuum chamber at NASA. It’s the only chamber that is adjoined to an ISO 6 cleanroom — a controlled environment that limits the number and size of airborne particles to minimize contamination.
The IMAP mission will launch on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida, no earlier than September.

NASA’s James Webb Space Telescope’s observations of what is thought to be the first-ever recorded planetary engulfment event revealed a hot accretion disk surrounding the star, with an expanding cloud of cooler dust enveloping the scene. Webb also revealed that the star did not swell to swallow the planet, but the planet’s orbit actually slowly depreciated over time, as seen in this artist’s concept. Full illustration below. Credits:
NASA, ESA, CSA, R. Crawford (STScI) Observations from NASA’s James Webb Space Telescope have provided a surprising twist in the narrative surrounding what is believed to be the first star observed in the act of swallowing a planet. The new findings suggest that the star actually did not swell to envelop a planet as previously hypothesized. Instead, Webb’s observations show the planet’s orbit shrank over time, slowly bringing the planet closer to its demise until it was engulfed in full.
“Because this is such a novel event, we didn’t quite know what to expect when we decided to point this telescope in its direction,” said Ryan Lau, lead author of the new paper and astronomer at NSF NOIRLab (National Science Foundation National Optical-Infrared Astronomy Research Laboratory) in Tuscon, Arizona. “With its high-resolution look in the infrared, we are learning valuable insights about the final fates of planetary systems, possibly including our own.”
Two instruments aboard Webb conducted the post-mortem of the scene – Webb’s MIRI (Mid-Infrared Instrument) and NIRSpec (Near-Infrared Spectrograph). The researchers were able to come to their conclusion using a two-pronged investigative approach.

Crawford (STScI) Constraining the How
The star at the center of this scene is located in the Milky Way galaxy about 12,000 light-years away from Earth.
The brightening event, formally called ZTF SLRN-2020, was originally spotted as a flash of optical light using the Zwicky Transient Facility at the Palomar Observatory in San Diego, California. Data from NASA’s NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) showed the star actually brightened in the infrared a year before the optical light flash, hinting at the presence of dust. This initial 2023 investigation led researchers to believe that the star was more Sun-like, and had been in the process of aging into a red giant over hundreds of thousands of years, slowly expanding as it exhausted its hydrogen fuel.
However, Webb’s MIRI told a different story. With powerful sensitivity and spatial resolution, Webb was able to precisely measure the hidden emission from the star and its immediate surroundings, which lie in a very crowded region of space. The researchers found the star was not as bright as it should have been if it had evolved into a red giant, indicating there was no swelling to engulf the planet as once thought.
Reconstructing the Scene
Researchers suggest that, at one point, the planet was about Jupiter-sized, but orbited quite close to the star, even closer than Mercury’s orbit around our Sun. Over millions of years, the planet orbited closer and closer to the star, leading to the catastrophic consequence.
“The planet eventually started to graze the star’s atmosphere. Then it was a runaway process of falling in faster from that moment,” said team member Morgan MacLeod of the Harvard-Smithsonian Center for Astrophysics and the Massachusetts Institute of Technology in Cambridge, Massachusetts. “The planet, as it’s falling in, started to sort of smear around the star.”
In its final splashdown, the planet would have blasted gas away from the outer layers of the star. As it expanded and cooled off, the heavy elements in this gas condensed into cold dust over the next year.
Inspecting the Leftovers
While the researchers did expect an expanding cloud of cooler dust around the star, a look with the powerful NIRSpec revealed a hot circumstellar disk of molecular gas closer in. Furthermore, Webb’s high spectral resolution was able to detect certain molecules in this accretion disk, including carbon monoxide.
“With such a transformative telescope like Webb, it was hard for me to have any expectations of what we’d find in the immediate surroundings of the star,” said Colette Salyk of Vassar College in Poughkeepsie, New York, an exoplanet researcher and co-author on the new paper. “I will say, I could not have expected seeing what has the characteristics of a planet-forming region, even though planets are not forming here, in the aftermath of an engulfment.”
The ability to characterize this gas opens more questions for researchers about what actually happened once the planet was fully swallowed by the star.
“This is truly the precipice of studying these events. This is the only one we’ve observed in action, and this is the best detection of the aftermath after things have settled back down,” Lau said. “We hope this is just the start of our sample.”
These observations, taken under Guaranteed Time Observation program 1240, which was specifically designed to investigate a family of mysterious, sudden, infrared brightening events, were among the first Target of Opportunity programs performed by Webb. These types of study are reserved for events, like supernova explosions, that are expected to occur, but researchers don’t exactly know when or where. NASA’s space telescopes are part of a growing, international network that stands ready to witness these fleeting changes, to help us understand how the universe works.
Researchers expect to add to their sample and identify future events like this using the upcoming Vera C. Rubin Observatory and NASA’s Nancy Grace Roman Space Telescope, which will survey large areas of the sky repeatedly to look for changes over time.
The team’s findings appear today in The Astrophysical Journal.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Long before joining NASA’s Test and Evaluation Support Team contract in October 2024, Angel Saenz was already an engineer at heart.
A STEM education program at his high school helped unlock that passion, setting him on a path that would eventually lead to NASA’s White Sands Test Facility in Las Cruces, New Mexico.
Angel Saenz poses in front of a composite overwrap pressure vessel outside of his office at White Sands Test Facility in Las Cruces, New Mexico. NASA/Anthony L. Quiterio The program – FIRST Robotics Competition – is run by global nonprofit, FIRST (For Inspiration and Recognition of Science and Technology). It was the brainchild of prolific inventor Dean Kamen, best known for creating the Segway.
In what the organization calls “the ultimate sport for the mind,” teams of students spend six weeks working under adult mentors—and strict rules—to design, program, and build industrial-sized robots before facing off in a themed tournament. Teams earn points for accomplishing various engineering feats, launching, grappling, and climbing their way through the obstacles of a game that’s less football and more American Ninja Warrior.
Competing during the 2013 and 2014 seasons with the White Sands-sponsored Deming Thundercats, Saenz said FIRST was a link between abstract mathematical ideas and real-world applications.
“Before joining FIRST, equations were just something I was told to solve for a grade, but now I was applying them and seeing how they were actually useful,” he said.
By turning education into an extracurricular activity as compelling as video games and as competitive as any varsity sport, FIRST completely reshaped Saenz’s approach to learning.
“There are lots of other things kids can choose to do outside of school, but engineering was always that thing for me,” he said. “I associate it with being a fun activity, I see it more as a hobby.”
That kind of energy—as any engineer knows—cannot be destroyed. Today Saenz channels it into his work, tackling challenges with White Sand’s Composite Pressure group where he tests and analyzes pressure vessel systems, enabling their safe use in space programs.
“Having that foundation really helps ground me,” he said. “When I see a problem, I can look back and say, ‘That’s like what happened in FIRST Robotics and here’s how we solved it.’”
Deming High School teacher and robotics mentor David Wertz recognized Saenz’s aptitude for engineering, even when Saenz could not yet see it in himself.
“He wasn’t aware that we were using the engineering process as we built our robot,” Wertz said, “but he was always looking for ways to iterate and improve our designs.”
Saenz credits those early hands-on experiences for giving him a head start.
“It taught me a lot of concepts that weren’t supposed to be learned until college,” he said.
Armed with that knowledge, Saenz graduated from New Mexico State University in 2019 with a dual degree in mechanical and aerospace engineering.
Now 28 years old, Saenz is already an accomplished professional. He adds White Sands to an impressive resume that includes past experiences with Albuquerque-based global manufacturing company Jabil and Kirtland Airforce Base.
Though only five months into the job, Saenz’s future at White Sands was set into motion more than a decade ago when he took a field trip to the site with Wertz in 2013.
“The kind invitations to present at White Sands or to take a tour of the facility has inspired many of the students to pursue degrees in engineering and STEM,” Wertz said. “The partnership continues to allow students to see the opportunities that are available for them if they are willing to put in the work.”
In a full-circle moment, Saenz and Mr. Wertz recently found themselves together at White Sands once again for the 2024 Environmental, Innovation, Safety, and Health Day event. This time not as student and teacher, but as industry colleagues in a reunion that could not have been better engineered.
David Wertz and Angel Saenz attend White Sand’s Environmental, Innovation, Safety, and Health Day event on October 31, 2024. The 2025 FIRST Robotics World Competition will take place in Houston at the George R. Brown Convention Center from April 16 to April 19. NASA will host an exciting robotics exhibit at the event, showcasing the future of technology and spaceflight. As many as 60,000 energetic fans, students, and industry leaders are expected to attend.

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.

El equipo detrás del X-59 de la NASA completó en marzo otra prueba crítica en tierra, garantizando que el silencioso avión supersónico será capaz de mantener una velocidad específica durante su funcionamiento. Esta prueba, conocida como mantenimiento automático de velocidad del motor, es el más reciente marcador de progreso a medida que el X-59 se acerca a su primer vuelo este año.
“El mantenimiento automático de la velocidad del motor es básicamente la versión de control de crucero de la aeronave,” explicó Paul Dees, jefe adjunto de propulsión de la NASA del X-59 en el Centro de Investigación de Vuelo Armstrong de la agencia en Edwards, California. “El piloto activa el control de velocidad a su velocidad actual y luego puede aumentarla o ajustarla gradualmente según sea necesario.”
El equipo del X-59 ya había realizado una prueba similar en el motor, pero sólo como un sistema aislado. La prueba de marzo verificó que la retención de velocidad funciona correctamente tras su integración en la aviónica de la aeronave.
“Necesitábamos verificar que el mantenimiento automático de velocidad funcionara no sólo dentro del propio motor, sino como parte de todo el sistema del avión,” explicó Dees. “Esta prueba confirmó que todos los componentes – software, enlaces mecánicos y leyes de control – funcionan juntos según lo previsto.”
El éxito de la prueba confirmó la habilidad de la aeronave para controlar la velocidad con precisión, lo cual será muy invaluable durante el vuelo. Esta capacidad aumentará la seguridad de los pilotos, permitiéndoles enfocarse en otros aspectos críticos de la operación de vuelo.
“El piloto va a estar muy ocupado durante el primer vuelo, asegurándose de que la aeronave sea estable y controlable,” dijo Dees. “Al tener la función del mantenimiento automático de velocidad, de reduce parte de esa carga de trabajo, lo que hace que el primer vuelo sea mucho más seguro.”
Inicialmente el equipo tenía planeado comprobar el mantenimiento automático de velocidad como parte de una próxima serie de pruebas en tierra donde alimentarían la aeronave con un sólido conjunto de datos para verificar su funcionalidad tanto en condiciones normales como de fallo, conocidas como pruebas de pájaro de aluminio (una estructura que se utiliza para probar los sistemas de una aeronave en un laboratorio, simulando un vuelo real). Sin embargo, el equipo se dio cuenta que había una oportunidad de probarlo antes.
“Fue un objetivo de oportunidad,” dijo Dees. “Nos dimos cuenta de que estábamos listos para probar el mantenimiento automático de velocidad del motor por separado mientras otros sistemas continuaban con la finalización de su software. Si podemos aprender algo antes, siempre es mejor.”
Con cada prueba exitosa, el equipo integrado de la NASA y Lockheed Martin acerca el X-59 al primer vuelo, y hacer historia en la aviación a través de su tecnología supersónica silenciosa.
