Preparations for Next Moonwalk Simulations Underway (and Underwater)
Students from Tropico Middle School in Rosamond, California, build their own paper planes as part of a project during NASA Aero Fair on April 9, 2025.NASA/Genaro Vavuris A new generation of aerospace explorers will soon embark on a hands-on summer experience focusing on careers in science, mathematics, engineering, and technology (STEM). This month, NASA’s Armstrong Flight Research Center in Edwards, California, and the Flight Test Museum Foundation will launch the 2025 Junior Test Pilot School.
Held at Blackbird Airpark and Joe Davies Heritage Airpark in Palmdale, California, this six-week program invites elementary-aged students to step into the shoes of test pilots and engineers from 9 a.m. to 2 p.m. Mondays through Fridays, June 16 through July 25. Registration is free through participating school districts and the Flight Test Museum. Students will have direct access to legendary aircraft such as A-12, SR-71, U-2, F-86 Sabre, and NASA Boeing 747 Space Shuttle Carrier Aircraft.
The Junior Test Pilot School combines authentic NASA-designed curriculum, immersive aerospace activities, and direct engagement with engineers, test pilots, and scientists to inspire future aerospace professionals in the Antelope Valley – home to one of the nation’s highest concentrations of STEM careers.
“This program offers more than a glimpse into aerospace, it provides students a hands-on opportunity to solve real-world problems and see themselves in future STEM roles,” said Dr. Amira Flores, program integration manager for NASA’s California Office of STEM Engagement.
Daily lessons cover eight core modules: flight principles, stealth engineering, altitude effects, speed and g-force, payload impact, maneuverability, reconnaissance design, and jet engine systems.
Additionally, in collaboration with NASA Armstrong’s Aero Fair program, students will be guided through the program’s Wildfire Design Challenge by a NASA volunteer. Following the engineering design process, students will collaborate to design and build a prototype of an aerial vehicle that suppresses wildfires.
“Our junior test pilots learn to analyze the aircraft to figure out why they were designed the way they are and think like an engineer,” said Lisa Sheldon Brown, director of education at the Flight Test Museum. “Research shows that academic trajectory is set by fifth grade, making this the critical window to inspire STEM interest and career awareness.”
The program is delivered in partnership with the City of Palmdale and is supported by industry sponsors, including Lockheed Martin and Northrop Grumman. These partners not only provide funding and volunteers but also elevate career exposure by introducing students to diverse aerospace professionals within the region.
NASA Armstrong is a hub of aeronautical innovation and STEM workforce development in the Antelope Valley. Through programs like Aero Fair and partnerships like Junior Test Pilots School, Armstrong inspires and equips the next generation of engineers, pilots, and scientists.
The Flight Test Museum Foundation preserves the legacy and promotes the future of aerospace through education programs and historical preservation at the Blackbird Airpark and forthcoming Flight Test Museum at Edwards Air Force Base in Edwards, California.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
What happens when the universe’s most magnetic object shines with the power of 1000 Suns in a matter of seconds? Thanks to NASA’s IXPE (Imaging X-ray Polarimetry Explorer), a mission in collaboration with ASI (Italian Space Agency), scientists are one step closer to understanding this extreme event.
Magnetars are a type of young neutron star – a stellar remnant formed when a massive star reaches the end of its life and collapses in on itself, leaving behind a dense core roughly the mass of the Sun, but squashed down to the size of a city. Neutron stars display some of the most extreme physics in the observable universe and present unique opportunities to study conditions that would otherwise be impossible to replicate in a laboratory on Earth.

Illustrated magnetar flyby sequence showing magnetic field lines. A magnetar is a type of isolated neutron star, the crushed, city-size remains of a star many times more massive than our Sun. Their magnetic fields can be 10 trillion times stronger than a refrigerator magnet's and up to a thousand times stronger than a typical neutron star's. This represents an enormous storehouse of energy that astronomers suspect powers magnetar outbursts.NASAs Goddard Space Flight Center/Chris Smith (USRA) The magnetar 1E 1841-045, located in the remnants of a supernova (SNR Kes 73) nearly 28,000 light-years from Earth, was observed to be in a state of outburst by NASA’s Swift, Fermi, and NICER telescopes on August 21, 2024.
A few times a year, the IXPE team approves requests to interrupt the telescope’s scheduled observations to instead focus on unique and unexpected celestial events. When magnetar 1E 1841-045 entered this brighter, active state, scientists decided to redirect IXPE to obtain the first-ever polarization measurements of a flaring magnetar.
Magnetars have magnetic fields several thousand times stronger than most neutron stars and host the strongest magnetic fields of any known object in the universe. Disturbances to their extreme magnetic fields can cause a magnetar to release up to a thousand times more X-ray energy than it normally would for several weeks. This enhanced state is called an outburst, but the mechanisms behind them are still not well understood.
Through IXPE’s X-ray polarization measurements, scientists may be able to get closer to uncovering the mysteries of these events. Polarization carries information about the orientation and alignment of the emitted X-ray light waves; the higher the degree of polarization, the more the X-ray waves are traveling in sync, akin to a tightly choreographed dance performance. Examining the polarization characteristics of magnetars reveals clues about the energetic processes producing the observed photons as well as the direction and geometry of the magnetar magnetic fields.
The IXPE results, aided by observations from NASA’s NuSTAR and NICER telescopes, show that the X-ray emissions from 1E 1841-045 become more polarized at higher energy levels while still maintaining the same direction of propagation. A significant contribution to this high polarization degree comes from the hard X-ray tail of 1E 1841-045, an energetic magnetospheric component dominating the highest photon energies observed by IXPE. “Hard X-rays” refer to X-rays with shorter wavelengths and higher energies than “soft X-rays.” Although prevalent in magnetars, the mechanics driving the production of these high energy X-ray photons are still largely unknown. Several theories have been proposed to explain this emission, but now the high polarization associated with these hard X-rays provide further clues into their origin.
This illustration depicts IXPE’s measurements of X-ray polarization emitting from magnetar 1E 1841-045 located within the Supernova Remnant Kes 73. At the time of observation, the magnetar was in a state of outburst and emitting the luminosity equivalent to 1000 suns. By studying the X-ray polarization of magnetars experiencing an outburst scientists may be able to get closer to uncovering the mysteries of these events. Michela Rigoselli/Italian National Institute of Astrophysics The results are presented in two papers published in The Astrophysical Journal Letters, one led by Rachael Stewart, a PhD student at George Washington University, and the other by Michela Rigoselli of the Italian National Institute of Astrophysics..
“This unique observation will help advance the existing models aiming to explain magnetar hard X-ray emission by requiring them to account for this very high level of synchronization we see among these hard X-ray photons,” said Stewart. “This really showcases the power of polarization measurements in constraining physics in the extreme environments of magnetars.”
Rigoselli, lead author of the companion paper, added, “It will be interesting to observe 1E 1841-045 once it has returned to its quiescent, baseline state to follow the evolution of its polarimetric properties.”
IXPE is a space observatory built to discover the secrets of some of the most extreme objects in the universe. Launched in December 2021 from NASA’s Kennedy Space Center on a Falcon 9 rocket, the IXPE mission is part of NASA’s Small Explorer series.
IXPE, which continues to provide unprecedented data enabling groundbreaking discoveries about celestial objects across the universe, is a joint NASA and Italian Space Agency mission with partners and science collaborators in 12 countries. IXPE is led by NASA’s Marshall Space Flight Center in Huntsville, Alabama. BAE Systems, headquartered in Falls Church, Virginia, manages spacecraft operations together with the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A lot can change in a year for Earth’s forests and vegetation, as springtime and rainy seasons can bring new growth, while cooling temperatures and dry weather can bring a dieback of those green colors. And now, a novel type of NASA visualization illustrates those changes in a full complement of colors as seen from space.
Researchers have now gathered a complete year of PACE data to tell a story about the health of land vegetation by detecting slight variations in leaf colors. Previous missions allowed scientists to observe broad changes in chlorophyll, the pigment that gives plants their green color and also allows them to perform photosynthesis. But PACE now allows scientists to see three different pigments in vegetation: chlorophyll, anthocyanins, and carotenoids. The combination of these three pigments helps scientists pinpoint even more information about plant health. Credit: NASA’s Goddard Space Flight Center NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite is designed to view Earth’s microscopic ocean plants in a new lens, but researchers have proved its hyperspectral use over land, as well.
Previous missions measured broad changes in chlorophyll, the pigment that gives plants their green color and also allows them to perform photosynthesis. Now, for the first time, PACE measurements have allowed NASA scientists and visualizers to show a complete year of global vegetation data using three pigments: chlorophyll, anthocyanins, and carotenoids. That multicolor imagery tells a clearer story about the health of land vegetation by detecting the smallest of variations in leaf colors.
“Earth is amazing. It’s humbling, being able to see life pulsing in colors across the whole globe,” said Morgaine McKibben, PACE applications lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It’s like the overview effect that astronauts describe when they look down at Earth, except we are looking through our technology and data.”
Anthocyanins, carotenoids, and chlorophyll data light up North America, highlighting vegetation and its health.Credit: NASA’s Scientific Visualization Studio Anthocyanins are the red pigments in leaves, while carotenoids are the yellow pigments – both of which we see when autumn changes the colors of trees. Plants use these pigments to protect themselves from fluctuations in the weather, adapting to the environment through chemical changes in their leaves. For example, leaves can turn more yellow when they have too much sunlight but not enough of the other necessities, like water and nutrients. If they didn’t adjust their color, it would damage the mechanisms they have to perform photosynthesis.
In the visualization, the data is highlighted in bright colors: magenta represents anthocyanins, green represents chlorophyll, and cyan represents carotenoids. The brighter the colors are, the more leaves there are in that area. The movement of these colors across the land areas show the seasonal changes over time.
In areas like the evergreen forests of the Pacific Northwest, plants undergo less seasonal change. The data highlights this, showing comparatively steadier colors as the year progresses.
The combination of these three pigments helps scientists pinpoint even more information about plant health.
“Shifts in these pigments, as detected by PACE, give novel information that may better describe vegetation growth, or when vegetation changes from flourishing to stressed,” said McKibben. “It’s just one of many ways the mission will drive increased understanding of our home planet and enable innovative, practical solutions that serve society.”
The Ocean Color Instrument on PACE collects hyperspectral data, which means it observes the planet in 100 different wavelengths of visible and near infrared light. It is the only instrument – in space or elsewhere – that provides hyperspectral coverage around the globe every one to two days. The PACE mission builds on the legacy of earlier missions, such as Landsat, which gathers higher resolution data but observes a fraction of those wavelengths.
In a paper recently published in Remote Sensing Letters, scientists introduced the mission’s first terrestrial data products.
“This PACE data provides a new view of Earth that will improve our understanding of ecosystem dynamics and function,” said Fred Huemmrich, research professor at the University of Maryland, Baltimore County, member of the PACE science and applications team, and first author of the paper. “With the PACE data, it’s like we’re looking at a whole new world of color. It allows us to describe pigment characteristics at the leaf level that we weren’t able to do before.”
As scientists continue to work with these new data, available on the PACE website, they’ll be able to incorporate it into future science applications, which may include forest monitoring or early detection of drought effects.
