A Sunflower’s View of Totality

A composite photo shows the Sun at several times and locations during the progression of a total solar eclipse. The Sun’s path descends diagonally from the top left across a dimmed sky, with a field of sunflowers in the foreground.
A composite image shows the progression of a total solar eclipse over San Millán de los Caballeros, Spain, on August 12, 2026.

Skywatchers across a swath of northern Spain witnessed a total solar eclipse when the Moon lined up directly between the Sun and Earth on August 12, 2026. Those within the path of totality had the rare chance to glimpse the Sun’s active outer atmosphere, or corona, during the short time the Moon blocked the Sun.

This composite photo was taken before, during, and after the total eclipse from a field of appropriately themed flowers in San Millán de los Caballeros, a town about 40 kilometers (25 miles) south of León in northwestern Spain. Along with parts of Greenland and Iceland, Northern Spain was one of the few places on land that fell within this eclipse’s path of totality.

Sunset was approaching when the Moon’s shadow, or umbra, swept across Spain. In León, the partial eclipse began at 7:32 p.m. and ended at 9:22 p.m. local time, just minutes before the Sun dipped below the horizon. Totality lasted about two minutes, starting at 8:28 p.m. Farther east in Spain, the Sun set before the eclipse ended.

In the photo above, taken during totality, a glowing loop of plasma called a solar prominence is visible extending into the corona on the left. Plasma, a super-hot gas composed mostly of ionized hydrogen and helium, flows along the tangled and twisted structure of the Sun’s magnetic fields. Solar prominences, which can measure many times higher than Earth is wide, are sometimes visible to the naked eye during eclipses.

Solar eclipses offer NASA the opportunity to get a different look at the Sun and our own atmosphere. On August 12, science teams staged in Iceland to chase the Moon’s shadow in one of NASA’s WB-57 high-altitude jets and image the corona in visible and infrared light. And the NASA-supported Nationwide Eclipse Ballooning Project launched scientific balloons before, during, and after the eclipse to measure how Earth’s atmosphere changed when the Sun was temporarily blocked.

While viewing opportunities in the path of totality were limited, the rest of Europe and parts of Africa, Canada, and the U.S. experienced a partial eclipse. Photos and video from the total and partial eclipse are available in NASA’s image library. The next total solar eclipse will occur on August 2, 2027, with the path of totality crossing southern Spain, North Africa, Saudi Arabia, and Yemen.

NASA’s 737 aircraft was painted this week in Oklahoma as it progresses with modifications for use as a reduced gravity test aircraft for the agency. NASA’s Armstrong Flight Research Center in Edwards, California, took ownership of the aircraft from the United States Air Force in June. 

The aircraft will perform lunar-gravity parabolic flights to validate astronaut lunar suits and associated crew systems required to support Artemis mission objectives. These flights will happen at NASA’s Johnson Space Center in Houston for reduced-gravity operations, with NASA Armstrong oversight.

In addition, the aircraft will serve as a key asset for systems‑integration research for flight testing autonomy, sensors, and other digital systems.

For West Virginia Engineer, Home Is Where the Heart Is… and NASA, Too

New civil servants pose together.
NASA’s Katherine Johnson Independent Verification and Validation Facility (IV&V) held a swearing-in ceremony for civil servants on Monday, Aug. 10, 2026, at the facility in Fairmont, West Virginia. In total, 51 new employees were hired at IV&V as part of NASA Administrator Jared Isaacman’s directive to strengthen NASA’s technical core competencies.

Growing up in Grafton, West Virginia, engrossed in Star Wars and all things science fiction, Fletcher Newell had an early interest in space exploration. That interest only grew when, in 2013, his fourth-grade class took a field trip to a nearby NASA facility he had not yet heard of – NASA’s Katherine Johnson Independent Verification & Validation Facility, located in nearby. Thirteen years later, Newell and 48 of his colleagues at the facility were sworn in as NASA civil servants during a ceremony on Aug. 10.

“I had always admired NASA from afar,” said Newell, who started working at IV&V as a systems engineer contractor in early 2025. “To my surprise, the agency was doing impactful work in my backyard.”
 
During high school, he began cultivating programming skills that would lay the foundation for his future. A self-professed computer aficionado, Newell taught himself how to code. In algebra class, he discovered that his graphing calculator was programmable, leading him to create basic scripts. He quickly moved to popular software applications, learning how they were built in order to develop his own programs. Artificial intelligence was still on the brink of becoming mainstream, but he was already asking himself, “What are the more interesting things we can teach computers to do?” As a junior in 2019, the precocious programmer merged his talents with his passion for space after being accepted into IV&V’s high school internship program.
Newell created a database for engineering methods, processing hundreds of documents to facilitate the work of his colleagues from a procedural aspect.

“Working as a high school intern really elevated my fascination for NASA,” he said.
 
Following graduation in 2020, Newell headed west to Stanford University in Palo Alto, California, majoring in, naturally, computer science, with a focus on AI and machine learning when both were scaling rapidly across industries and in everyday usage.
 
Instead of pursuing internships in the neighboring Silicon Valley – widely considered the global center for technological innovation – he returned to West Virginia for three consecutive summers, cutting his teeth at the Fairmont facility.

He began researching AI safety as engineers learned how to give spacecraft more onboard autonomy and have them learn on their own. Later, he was on a team responsible for assessing the safety of Terrain Relative Navigation, a vision-based guidance technology that could enable spacecraft to land on planetary surfaces without GPS. During his final internship, generative AI – which creates content based on user prompts – was becoming widespread, and he worked on teams exploring how to responsibly integrate it into mission assurance.
 
Newell also performed research about autonomous space docking at Stanford’s Center for AI Safety, resulting in two publications. Following his undergraduate education, he remained at Stanford to earn a master’s in computer science.
 
When it came time to enter the workforce, one organization was atop his list. A contractor opportunity opened up at IV&V, and he leapt at the chance.
 
“I enjoyed the work at IV&V back in high school and college,” he said. “There’s nothing better than pursuing what aligns with your interests.”
 
As a systems engineer, he has worked primarily on mission safety and security, identifying and resolving system defects and vulnerabilities for such spacecraft as Space Reactor-1 (SR-1) Freedom, Orion, Gateway, and the Human Landing System, all while helping guide NASA’s responsible adoption and development of AI systems.
 
His colleagues took notice of their junior member’s contributions, resulting in Newell being named IV&V Engineer of the Year in 2025 less than a year into the job after identifying more than 70 issues in Gateway – and later SR-1 Freedom – with clear mission impact and, as noted in his award citation, developing a reputation for clearly articulating their implications.
 
“During his internships and now as a full-time engineer, Fletcher has consistently demonstrated exceptional talent, curiosity, and a passion for our mission,” said Wes Deadrick, IV&V director. “He could have gone almost anywhere after Stanford. The fact that he chose to come home to build his career supporting NASA through the IV&V Program makes me incredibly proud.”
 
The Aug. 10 ceremony for Newell and his colleagues was part of NASA’s workforce directive to bring core, mission-critical positions into the civil service, from early-career professionals to seasoned technical experts.
 
“It’s an investment in NASA’s future, giving us the opportunity to bring exceptionally talented people into the civil service while strengthening long-term technical capabilities that support our nation’s most challenging missions,” said Deadrick. “At IV&V, initiatives like this help ensure we continue providing independent expertise and mission assurance that our customers depend on.”
 
For Newell, as he takes this next step in his professional progression as a civil servant computer engineer, he looks forward to expanding on his responsibilities, especially to help NASA return to the Moon. He is currently helping identify safety and security issues, including ones that could impact crew safety and lead to the loss of spacecraft control, related to the agency’s lunar endeavors.
 
“At IV&V, teams are ensuring every major lunar vehicle and system will be ready to safely embark on their missions, not just for flying around the Moon, but also for putting American boots on the surface and eventually establishing and working on a Moon Base,” he said.
 
More than a decade after taking that field trip and now working on some of NASA’s high-priority missions, Newell readily admits he didn’t always envision staying in West Virginia.
 
“It was a little strange coming back, but I was continually getting to do amazing things at an amazing organization in a place I already know,” Newell said. “And that’s really cool.”

APOD: 2026 August 13 – Total Solar Eclipse Over Spain

APOD

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

The Moon covers the Sun in the middle of the sky above an ornate church. A ring of bright whisps from the Sun's corona surrounds the Moon. In front of the church is a river that shows ripples across the eclipse's reflection. Some people are boating in the river.

Total Solar Eclipse Over Spain

Explanation: On August 12th, 2026, the Moon totally eclipsed the Sun and cast its shadow across Siberia, Greenland, Iceland, Spain, and Portugal. Today’s image features two total solar eclipses viewed from Zaragoza, Spain, one over the Cathedral-Basilica of Our Lady of the Pillar and the other reflecting in the Ebro River. For a few moments, Spain saw its first major total solar eclipse since 1905. Those witnessing totality may experience a chill in the air, the quieting of birds, the confused chirps of insects, and the shared awe of many. It’s the corona’s time to shine as the Sun’s bright disk is blocked by the Moon. Among other reasons to study eclipses, they help scientists understand why the corona is millions of degrees hotter than the Sun’s surface. Enthusiastic citizens can contribute to these studies by recording how wildlife responds, imaging the corona, and monitoring air temperature and clouds.

NASA Upgrades Vertical Motion Simulator for Modern Mission Needs

2 min read

Preparations for Next Moonwalk Simulations Underway (and Underwater)

The Vertical Motion Simulator at NASA’s Ames Research Center in California’s Silicon Valley is capable of vertical and horizontal motion to simulate a range of flight experiences, such as lunar landers, helicopters, and commercial aircraft.

Imagine stepping into a machine that can make you feel like you’re flying a spacecraft, piloting a next generation air taxi, or landing on the Moon, all without leaving the ground. NASA’s Vertical Motion Simulator, the largest of its kind in the world, does exactly that. And now, with new upgrades, it’s more powerful and realistic than before.

The Vertical Motion Simulator, located at NASA’s Ames Research Center in California’s Silicon Valley, has shaped the future of aviation and spaceflight since 1979. It allows pilots and researchers to experience realistic aircraft motion due to its ability to travel 60 feet vertically and 40 feet horizontally, simulating vehicles ranging from helicopters to spacecraft with high accuracy.

New improvements are making the simulator even more powerful. One of the biggest changes is the switch from analog systems to modern digital technology. This upgrade includes a dome surrounding the simulator’s cockpit with advanced 4K projectors that create visuals with nearly 20/20 clarity, giving pilots clearer, sharper images and a larger field of view of the world outside the cockpit.

The upgraded cab of the Vertical Motion Simulator at NASA’s Ames Research Center in California’s Silicon Valley provides researchers with near-20/20 visual clarity, providing clearer, sharper images.
NASA/Brandon Torres-Navarrete

“The new dome configuration and improved systems can support far more aggressive mission tasks while giving pilots and crews a more realistic environment to work in,” said Diana Acosta, aerospace simulation research and development branch chief at NASA Ames. “It strengthens how teams coordinate, react, and manage challenging scenarios, exactly the kind of preparation we need for the missions coming next.”

The system also can automatically line up and color‑match images to integrate them into a simulated background, a process that used to take hours, or even days, to do by hand.

In the past, changing simulation configurations from lunar lander to air taxi required swapping out the cab, a large, heavy structure that was time‑consuming and complex to move. Instead of replacing an entire cab, teams can use lighter, removable inserts that include only the controls, seats, and panels needed to stand in for a specific vehicle. The inserts drastically reduce physical labor and cut the time needed to configure a simulation in half.

The upgrades to the Vertical Motion Simulator will enable tests of next-generation aircraft and spacecraft before they ever leave the ground, bringing us closer to safer skies, more efficient air travel, and successful human landings on the Moon and Mars.

Quality Assessment Report Evaluates Polar Geospatial Center EarthDEM Elevation Products

A new quality assessment report from NASA’s Commercial Satellite Data Acquisition (CSDA) program evaluates data from the Polar Geospatial Center’s (PGC) EarthDEM product. The results of the evaluation help inform NASA program management and the user community about the quality of commercial Digital Elevation Models (DEMs) for use in NASA science.

Issued August 8, 2026, the CSDA  Polar Geospatial Center EarthDEM Quality Assessment Reportwas conducted by NASA Digital Elevation Model (DEM) subject matter experts (SMEs) enlisted to evaluate the horizontal and vertical accuracy of two PGC EarthDEM1 (i.e., Digital Elevation Model) products: the center’s “Mosaic Tile” and “Strip” Digital Surface Models (DSMs).

To assess the vertical and horizontal accuracy of the EarthDEM Strip DSM and Mosaic Tile products over a variety of surface characteristics, the SMEs compared them to airborne lidar data samples from across the United States and Senegal. They found the horizontal accuracy of the EarthDEM products (Strip DSM: 0.5-meter (m) Root Mean Square Error Horizontal (RMSEH); Mosaic Tile: 0.3 m RMSEH) agreed with the specifications provided by the PGC and graded them “Excellent.”  The vertical accuracy results of the EarthDEM Strip DSM (5.6 m Root Mean Square Error Vertical (RMSEV)) and the Mosaic Tile (4.9 m RMSEV) products varied by land cover type, with all land cover types exceeding the specification provided by the PGC (0.5 m RMSEV). Strip DSM vertical accuracy was found to vary from 4.6-6.8 m RMSEV depending on the cloud cover metadata field generated by the PGC. Given this variation, the vertical accuracy compliance for the EarthDEM products was graded as “Basic.”

Overall, the assessment report supports the use of EarthDEM data for NASA Earth science research and applications, as long as the data characteristics (e.g., vertical accuracy, poor cloud masking, missing surface features, data voids, etc.) are compatible with the specific science objectives and use cases.

The report also provides a Data Provider Documentation Review for the EarthDEM product that evaluated information from the PGC website, as well as a series of peer-reviewed publications by researchers at The Ohio State University’s Byrd Polar and Climate Research Center. (Only documents listed in this report were considered in the evaluation.) The report’s authors found that, overall, the EarthDEM product is “well documented,” with most information present within the product User Guide, a series of peer reviewed papers, or the PGC GitHub repository.

About the CSDA Program

The CSDA program was established to identify, evaluate, and acquire data from commercial sources that support the NASA Earth science research and application goals. NASA’s Earth Science Division recognizes the potential impact commercial satellite constellations may have in encouraging/enabling efficient approaches to advancing Earth System Science and applications development for societal benefit. Commercially acquired data may also provide a cost-effective means to augment and/or complement the suite of Earth observations acquired by NASA, other U.S. government agencies, and international partners.

To read the reports in full, see the links under “Evaluation” heading on the Polar Geospatial Center vendor page on the CSDA website.

Notes:

1. According the authors of the report, “it should be noted that the PGC EarthDEM product is not technically a commercial product…. EarthDEM is a digital elevation dataset derived from imagery collected from the Vantor (formerly Maxar) fleet of optical satellites.”

Stops Along the Path of Totality

A peninsula in Iceland stretches across the image to the left. A prominent glacier-capped volcano sits near its western end.
The glacier-capped Snæfellsjökull volcano is the defining feature of Iceland’s Snæfellsnes peninsula, shown in this image acquired with the OLI (Operational Land Imager) on Landsat 9 on July 25, 2026.

The Sun, Moon, and Earth align on August 12, 2026, to produce a total solar eclipse. When this celestial event last occurred, on April 8, 2024, the path of totality stretched across North America, giving millions the chance to glimpse the Sun’s corona. In 2026, the viewing locales are more limited; only a handful of land areas in the Northern Hemisphere, including parts of Iceland and Spain, fall within the path of totality.

On August 12, the Moon’s shadow will first cross over the Arctic Circle from northern Russia and then track along the eastern side of Greenland. At about 5:45 p.m. local time in Iceland (17:45 Universal Time), the country’s western fringes—including the Snæfellsnes peninsula, shown in the Landsat image above—will begin to experience totality. The greatest eclipse will occur near this sparsely populated peninsula when the Moon appears the largest and covers more of the Sun.

A map shows the path of totality of the solar eclipse on August 12, 2026, arcing across Greenland, Iceland, the North Atlantic, and Spain.
The path of totality of the solar eclipse on August 12, 2026, spans Greenland, Iceland, and Spain. The base imagery for the map comes from Blue Marble: Next Generation, with data from Black Marble shown in the path of totality. Blue Marble is built from scenes captured by MODIS (Moderate Resolution Imaging Spectroradiometer), while Black Marble is based on observations by the VIIRS (Visible Infrared Imaging Radiometer Suite) day-night band.
NASA Earth Observatory/Michala Garrison

The Snæfellsjökull volcano on the western end of the peninsula is covered in ice and last erupted about 1,800 years ago. It is the highlight of a national park of the same name, where people are expected to visit to view the eclipse. The stratovolcano even has a literary claim to fame: in Jules Verne’s A Journey to the Center of the Earth, characters venture underground through its crater, later emerging in an eruption of Stromboli, in Italy. In 2025, a broader area of the peninsula was designated a UNESCO biosphere reserve, containing over 70 percent of Iceland’s flora and an agglomeration of volcanic landscapes, wetlands, and grasslands.

From Iceland, the eclipse shadow, or umbra, progresses across the North Atlantic and reaches northern Spain shortly before sunset. It runs east-southeast across the country, much like the Ebro River (Río Ebro), seen in the Landsat image below.

Meandering rivers cut through dark green mountain ridges, across agricultural land, and near several developed areas in northern Spain.

The Ebro River, meandering across northern Spain in this image acquired with the OLI (Operational Land Imager) on Landsat 8 on July 21, 2026, is in the path of totality of the August 2026 solar eclipse.
NASA Earth Observatory/Michala Garrison

The upper Ebro emerges from rugged terrain in Parque Natural de Montes Obarenes-San Zadornil, where it carves canyons and gorges through the eastern foothills of the Cantabrian Mountains. It then meanders through La Rioja, a region known for its vineyards. About 400 kilometers (250 miles) away, the river reaches a delta on the Mediterranean coast between Barcelona and Valencia.

Based on satellite measurements of cloud cover in August over several decades, viewers in Spain have a higher likelihood than those in Iceland of getting a clear look at the eclipse. And despite limited viewing opportunities in the path of totality, the rest of Europe, parts of Africa, Canada, and the northern and northeastern U.S. will experience a partial eclipse.
