NASA HEAT Student Activity Featured in TIME’s Top 100 Photos of 2024
On April 8, 2024, tens of millions experienced a solar eclipse from Mexico through the United States and into Canada. Astronomers, educators, and organizations had been preparing the public for this grand celestial event. Learning from engagement experiences in 2017, the NASA Heliophysics Education Activation Team (NASA HEAT) promoted an activity called “Eclipse Essentials: Safe and Stylish Solar Viewing Glasses.” The activity was first tested in Albuquerque, New Mexico during the Balloon Fiesta around the October 2023 annular eclipse. Using solar viewing glasses, a paper plate, some drawing and decoration supplies, visitors – minors and adults alike – crowded around the heliophysics tables in the NASA tent. That positive experience led NASA HEAT to modify and perfect the design of their “face shield” activity before offering trainings to numerous educators and outreach personnel in the weeks leading up to the April 2024 engagement events.
Note: The glasses and the art activity are not only useful for solar eclipses. They can be used anytime to safely observe the Sun. While it is never safe to look directly at the sun with unprotected eyes, eclipse glasses are perfect for observing sunspots!
One proof of positive impact can be found at the Myers Elementary School in Grand Blanc, Michigan. Students from two kindergarten classes, escorted outside by their teachers Amy Johnston and Wendy Sheridan, stared toward the sky with their solar viewing glasses using paper plates to watch the solar eclipse on Monday, April 8, 2024. The paper plates, which helped provide additional safety measures to protect their eyes, were attached to solar eclipse glasses and decorated by each student in their classrooms as a project leading up to the big day. A photo of the students was so captivating that multiple media outlets shared it on or shortly after the day of the eclipse.
The global media brand, TIME, selected a photo of these kindergarten students wearing their NASA HEAT-designed solar eclipse-viewing “face shields” during the April 8th solar eclipse as one of “TIME’s Top 100 Photos of 2024”. When sharing about the top 100 photos on Instagram, TIME had this to say:
“Every year the TIME photo department sits down to curate the strongest images that crossed our path over the previous 12 months. And every year, sitting with the images, we find ourselves mulling the ways this collection feels heavier than the last, how the year produced images unlike what we’ve seen before.
But this year something else, a tautness, runs through the collection – the tension of conflict, the anxiety over outcome, anticipation of excitement or in possibility. Somehow, these photographers are able to capture that coiled feeling and hold it within the four walls of a frame. Be it by impeccable timing or intentional framing, they have created a time capsule that feels as if it’s about to be opened.”

NASA Flights Map Critical Minerals from Skies Above Western US
Various minerals are revealed in vibrant detail in this sample mineral map of Cuprite, Nevada, following processing of imaging spectrometer data. USGS On a crystal-clear afternoon above a desert ghost town, a NASA aircraft scoured the ground for minerals.
The plane, a high-altitude ER-2 research aircraft, had taken off early that morning from NASA’s Armstrong Flight Research Center in Edwards, California. Below pilot Dean Neeley, the landscape looked barren and brown. But to the optical sensors installed on the plane’s belly and wing, it gleamed in hundreds of colors.
Neeley’s flight that day was part of GEMx, the Geological Earth Mapping Experiment led by NASA and the U.S. Geological Survey to map critical minerals across more than 190,000 square miles (500,000 square kilometers) of North American soil. Using airborne instruments, scientists are collecting these measurements over parts of California, Nevada, Arizona, and Oregon. That’s an area about the size of Spain.

The high-altitude plane supports a wide variety of research missions, including the GEMx campaign, which is mapping critical minerals in the Western U.S. using advanced airborne imaging developed by NASA. Credit: NASA/Carla Thomas Lithium, aluminum, rare earth elements such as neodymium and cerium — these are a few of the 50 mineral commodities deemed essential to U.S. national security, to the tech industry, and to clean energy. They support a wide range of technologies from smartphones to steelmaking, from wind turbines to electric vehicle batteries. In 2023, the U.S. imported its entire supply of 12 of these minerals and imported at least 50% of its supply of another 29.
The GEMx team believes that undiscovered deposits of at least some of these minerals exist domestically, and modern mineral maps will support exploration by the private sector.
“We’ve been exploring the earth beneath our feet for hundreds of years, and we’re discovering that we’ve only just begun,” said Kevin Reath, NASA’s associate project manager for GEMx.
The View From 65,000 Feet
To jumpstart mineral exploration, USGS is leading a nationwide survey from the inside out, using tools like lidar and magnetic-radiometric sensors to probe ancient terrain in new detail.
The collaboration with NASA brings another tool to bear: imaging spectrometers. These advanced optical instruments need to stay cold as they fly high. From cryogenic vacuum chambers on planes or spacecraft, they detect hundreds of wavelengths of light — from the visible to shortwave infrared — reflected off planetary surfaces. The technology is now being used to help identify surface minerals across dry, treeless expanses of the Western U.S.
Every molecule reflects a unique pattern of light, like a fingerprint. Processed through a spectroscopic lens, a desert expanse can appear like an oil painting popping with different colorful minerals, including pale-green mica, blue kaolinite, and plummy gypsum.
“We’re not digging for gold. We’re revealing what’s hidden in plain sight,” said Robert Green, a researcher at NASA’s Jet Propulsion Laboratory in Southern California, who helped pioneer spectroscopic imaging at NASA JPL in the late 1970s. Like many of the scientists involved with GEMx, he has spent years surveying other worlds, including the Moon and Mars.
A handful of such instruments exist on Earth, and Green is in charge of two of them. One, called EMIT (Earth Surface Mineral Dust Source Investigation) flies aboard the International Space Station. Surveying Earth’s surface from about 250 miles (410 kilometers) above, EMIT has captured thousands of images at a resolution of 50 by 50 miles (80 by 80 kilometers) in a wide belt around Earth’s mid-section.
The other instrument rides beneath the fuselage of the ER-2 aircraft. Called AVIRIS (Airborne Visible/Infrared Imaging Spectrometer), it’s helping guide geologists to critical minerals directly and indirectly, by spotting the types of rocks that often contain them. It’s joined by another instrument developed by NASA, the MODIS/ASTER Airborne Simulator (MASTER), which senses thermal infrared radiance. Both instruments provide finely detailed measurements of minerals that complement what EMIT sees on a broader scale.

In and around the multimillion-year-old magmas of the Great Basin of the Western U.S., lithium takes several forms. The silvery metal is found in salty brines, in clay, and locked in more than 100 different types of crystals. It can also be detected in the tailings of abandoned prospects like Hector Mine, near Barstow, California.
Abandoned years before a magnitude 7.1 earthquake rocked the region in 1999, the mine is located on a lode of hectorite, a greasy, lithium-bearing clay. Geologists from USGS are taking a second look at legacy mines like Hector as demand for lithium rises, driven primarily by lithium-ion batteries. A typical battery pack in an electric vehicle uses about 17 pounds (eight kilograms) of the energy-dense metal.
Australia and Chile lead worldwide production of lithium, which exceeded 180,000 tons in 2023. The third largest producer is China, which also hosts about 50% of global lithium refining capacity. Total U.S. production was around 1,000 tons, sourced entirely from a deposit in northern Nevada. Known reserves in the state are estimated to contain more than a million metric tons of lithium, according to data collected by the Nevada Bureau of Mines and Geology.
Mine wastes are also potential sources of lithium, said Bernard Hubbard, a remote sensing geologist at USGS, and many other byproduct commodities that are considered critical today but were discarded by previous generations.
“There are old copper and silver mines in the West that were abandoned long before anyone knew what lithium or rare earth element deposits were,” Hubbard said. “What has been a pollution source for communities could now be a resource.”
Following a winter pause, high-altitude GEMx flights over the American West will resume in the spring of 2025, after which USGS will process the raw data and release the first mineral maps. Already, the project has collected enough data to start producing a complete hyperspectral map of California — the first of its kind.
The value of these observations extends beyond identifying minerals. Scientists expect they’ll provide new insight into invasive plant species, waste from mines that can contaminate surrounding environments, and natural hazards such as earthquakes, landslides, and wildfires.
“We are just beginning to scratch the surface in applying these measurements to help the nation’s economy, security, and health,” said Raymond Kokaly, USGS research geophysicist and lead of the GEMx survey.
More About GEMx
The GEMx research project will last four years and is funded by the USGS Earth Mapping Resources Initiative (EarthMRI), through investments from the Bipartisan Infrastructure Law. The initiative will capitalize on both the technology developed by NASA for spectroscopic imaging as well as the expertise in analyzing the datasets and extracting critical mineral information from them.
Data collected by GEMx is available here.

NASA/JPL-Caltech This Oct. 4, 2017, illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian’s Star or Tabby’s Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler but longer-term dimming trends. Scientists proposed several explanations for this unexpected behavior, ranging from Tabby’s Star swallowing a planet to alien “megastructures” harvesting the star’s energy. However, a study using NASA’s Spitzer and Swift missions as well as the Belgian AstroLAB IRIS observatory suggests that the cause of the dimming over long periods is likely an uneven dust cloud moving around the star.

Video: 00:04:30 Explore the immense power of water as ESA’s Mars Express takes us on a flight over curving channels, streamlined islands and muddled ‘chaotic terrain’ on Mars, soaking up rover landing sites along the way.
This beautiful flight around the Oxia Palus region of Mars covers a total area of approximately 890 000 km2, more than twice the size of Germany. Central to the tour is one of Mars’s largest outflow channels, Ares Vallis. It stretches for more than 1700 km2 and cascades down from the planet’s southern highlands to enter the lower-lying plains of Chryse Planitia.
Billions of years ago, water surged through Ares Vallis, neighbouring Tiu Vallis, and numerous other smaller channels, creating many of the features observed in this region today.
Enjoy the flight!
After enjoying a spectacular global view of Mars we focus in on the area marked by the white rectangle. Our flight starts over the landing site of NASA’s Pathfinder mission, whose Sojourner rover explored the floodplains of Ares Vallis for 12 weeks in 1997.
Continuing to the south, we pass over two large craters named Masursky and Sagan. The partially eroded crater rim of Masursky in particular suggests that water once flowed through it, from nearby Tiu Vallis.
The Masurky Crater is filled with jumbled blocks, and you can see many more as we turn north to Hydaspis Chaos. This ‘chaotic terrain’ is typical of regions influenced by massive outflow channels. Its distinctive muddled appearance is thought to arise when subsurface water is suddenly released from underground to the surface. The resulting loss of support from below causes the surface to slump and break into blocks of various sizes and shapes.
Just beyond this chaotic array of blocks is Galilaei crater, which has a highly eroded rim and a gorge carved between the crater and neighbouring channel. It is likely that the crater once contained a lake, which flooded out into the surroundings. Continuing on, we see streamlined islands and terraced river banks, the teardrop-shaped island ‘tails’ pointing in the downstream direction of the water flow at the time.
Crossing over Ares Vallis again, the flight brings us to the smoother terrain of Oxia Planum and the planned landing site for ESA’s ExoMars Rosalind Franklin rover. The primary goal of the mission is to search for signs of past or present life on Mars, and as such, this once water-flooded region is an ideal location.
Zooming out, the flight ends with a stunning bird’s-eye view of Ares Vallis and its fascinating water-enriched neighbourhood.

How the movie was made
This film was created using the Mars Express High Resolution Stereo Camera Mars Chart (HMC30) data, an image mosaic made from single orbit observations of the High Resolution Stereo Camera (HRSC). The mosaic, centred at 12°N/330°E, is combined with topography information from the digital terrain model to generate a three-dimensional landscape.
For every second of the movie, 50 separate frames are rendered following a predefined camera path in the scene. A three-fold vertical exaggeration has been applied. Atmospheric effects such as clouds and haze have been added to conceal the limits of the terrain model. The haze starts building up at a distance of 300 km.
The HRSC camera on Mars Express is operated by the German Aerospace Center (DLR). The systematic processing of the camera data took place at the DLR Institute for Planetary Research in Berlin-Adlershof. The working group of Planetary Science and Remote Sensing at Freie Universität Berlin used the data to create the film.
