Sunlight beams off a partly cloudy Atlantic Ocean just after sunrise as the International Space Station orbited 263 miles above on March 5, 2025. This is an example of sunglint, an optical phenomenon that occurs when sunlight reflects off the surface of water at the same angle that a satellite sensor views it. The result is a mirror-like specular reflection of sunlight off the water and back at the satellite sensor or astronaut.

While sunglint often produces visually stunning images, the phenomenon can create problems for remote sensing scientists because it obscures features that are usually visible. This is particularly true for oceanographers who use satellites to study phytoplankton and ocean color. As a result, researchers have developed several methods to screen sunglint-contaminated imagery out of data archives.

Despite the challenges posed by sunglint, the phenomenon does offer some unique scientific opportunities. It makes it easier, for instance, to detect oil on the water surface, whether it is from natural oil seeps or human-caused oil spills. This is because a layer of oil smooths water surfaces.

After delivering about 12,000 pounds of supplies, scientific investigations, hardware, and other cargo to the International Space Station for NASA and its international partners, JAXA’s (Japan Aerospace Exploration Agency’s) uncrewed HTV‑X1 cargo spacecraft is scheduled to depart Friday, March 6.

Watch NASA’s live coverage beginning at 11:45 a.m. EST on NASA+, Amazon Prime, and the agency’s YouTube channel in advance of the spacecraft’s release at 12 p.m. Learn how to watch NASA content through a variety of online platforms, including social media.

On Thursday, March 5, flight controllers will use the space station’s Canadarm2 robotic arm to detach HTV-X1 from the Harmony module’s Earth-facing port on the station and maneuver it into position for release. NASA will not provide live coverage of the spacecraft’s detachment from the orbiting laboratory. NASA astronaut Chris Williams will monitor HTV-X1’s systems during undocking and departure.

The HTV-X1 spacecraft will remain in orbit for more than three months acting as a scientific platform for JAXA’s experiments. Following the deorbit command, the spacecraft will dispose of several thousand pounds of trash during re-entry into Earth’s atmosphere, where it will burn up harmlessly.

The spacecraft arrived at the space station on Oct. 29, 2025, after launching Oct. 25 on an H3 rocket from Japan’s Tanegashima Space Center.

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The space 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 concentrate on providing human space transportation services and destinations as part of a strong low Earth orbit economy, NASA is focusing its resources on deep space missions to the Moon as part of the Artemis campaign in preparation for future astronaut missions to Mars.

Since the 1970s, planetary geologists have known that volcanic features cover large swaths of Mars. Early Mariner 9 images revealed massive shield volcanoes and lava plains on a scale unlike anything on Earth. Olympus Mons, the tallest volcano in the solar system, stands nearly three times higher than Mount Everest. Alba Mons, the planet’s widest volcano, spans a distance comparable to the length of the continental United States.

Both Olympus Mons and Alba Mons were primarily built by basaltic effusive eruptions—relatively calm outpourings of “runny” lavas that spread across the surface in sheets. This is thought to be the most common type of volcanism on Mars, accounting for the vast majority of its volcanic landforms. However, a small portion was produced by explosive volcanism of the sort that forms volcanic cones, pyroclastic flows, and ashfalls.

The dearth of explosive volcanic features on Mars has long puzzled geologists. With an average atmospheric pressure 160 times lower than Earth’s and only a third of the gravity, explosive eruptions should theoretically occur more easily on the Red Planet, said Petr Brož, a planetary geologist with the Czech Academy of Sciences. That rarity is part of what makes features like the volcanic cones (shown above) found in Mars’ Ulysses Colles region so compelling to planetary geologists.

“They appear to be scoria cones—a clear sign of explosive volcanism,” Brož added. “They were the first identified in the Tharsis region in the 2010s, and they helped paint a broader and more complete picture of Martian volcanism.”

The CTX (Context Camera) on NASA’s Mars Reconnaissance Orbiter captured this image (second image above) of Ulysses Colles above on May 7, 2014. Ulysses Colles is located at the southern edge of Ulysses Fossae, a group of troughs within the Tharsis volcanic region.

The OLI (Operational Land Imager) on Landsat 8 captured an image with similar cones in the San Francisco Volcanic Field (SFVF) in northern Arizona on June 19, 2025 (top). Planetary geologists consider the cones in the two locations to be highly analogous. Both images also include grabens—linear blocks of crust that have shifted downward.

In both images, the scoria cones appear as rounded hills crowned with circular vents, while lava flows spread outward as dark, textured areas around the bases of the cones. At both locations, seemingly younger and smaller lava flows appear to spill from some cones, while older, more weathered flows lie in the background.

“Understanding similar features on Earth helps us know what to look for on Mars and interpret processes that we can’t observe directly,” said Patrick Whelley, a NASA volcanologist who is part of a team that develops field equipment and techniques for Moon and Mars exploration.

SP Crater (above left), located in Arizona’s San Francisco Volcanic Field, features a 7-kilometer-long lava flow that extends northward and has been used for NASA astronaut geology training. In two places, the flow has spilled into a graben, creating a distinctive half-moon pattern along its left side.

On Earth, scoria cones form when gas-rich magmas soar high into the air and solidify into small particles of material called scoria that accumulate in steep-sided structures. While similar processes create cones on Earth and Mars, there are important differences. Martian scoria cones are typically taller, wider, and have gentler slopes, Flynn said. That makes sense. With lower gravity and atmospheric pressure, volcanic fountains can loft erupted magma higher and farther from the vent, producing larger cones.

There are far more scoria cones on Earth, where tens of thousands exist and account for about 90 percent of volcanoes on land. On Mars, “we have only identified tens to a few hundred candidates,” Broz said. It could be that explosive volcanism was never common on Mars, or it could be that it was but that explosive features have been covered up by younger, effusive flows or destroyed by erosion, he added.   

Whelley noted that on Mars, it remains unclear whether the Martian lava flows or the scoria cones formed first. The lava flow could be older, with the cone forming on top. Or, the cone may have formed first and later become plugged, forcing lava to spill from its side. Determining the order of events is one of the “puzzles of geology” that planetary geologists try to solve when studying Martian features remotely, he said. “Visiting places like the San Francisco Volcanic Field and studying the geology of analogous features up close on Earth helps us know what clues to look for when interpreting Martian geology.”

Below (left) is a closer view of a scoria cone on Earth, southeast of SP Crater, called Sunset Crater. It erupted about 800 years ago, making it the youngest scoria cone in the San Francisco Volcanic Field. The analogous cone in Ulysses Colles (right), in contrast, is thought to be billions of years old.

Note that eruptions that create scoria cones are “mildly explosive,” usually Strombolian events, characterized by intermittent lava fountains, said Ian Flynn, a planetary geologist at the University of Pittsburgh. They differ from the far more violent explosive eruptions that send ash columns billowing tens of kilometers into the air, as happened at Hunga Tonga-Hunga Ha’apai in the South Pacific, he added.

Mars also shows evidence of highly explosive “super eruptions,” but that type of eruption leaves behind a different geologic signature: large depressions called paterae and broad, thin deposits of ash and other erodible material sculpted into landforms such as yardangs.

Planetary comparison is valuable for understanding the geology of distant worlds, Brož said. Without such comparisons, it becomes harder to determine how landforms on other planets or moons may have formed at all.

But caution is essential. “In planetary science, it’s often said—only half-jokingly—that even if something looks like a duck, behaves like a duck, and sounds like a duck, it may not actually be a duck,” he added. It’s easy, for instance, to confuse scoria cones with mud volcanoes.

Researchers are highly confident that the Ulysses Colles cones formed through explosive volcanism based on the surrounding volcanic landscape, but in more ambiguous terrain it can be difficult to tell. Mars is fundamentally different from Earth, he cautioned. Brož’s laboratory research suggests, for instance, that mud flows on Mars can look much like certain types of lava flows, and that, under certain conditions, they can even boil and levitate. “We also have to avoid being constrained by terrestrial experience,” he said. “If we fail to think outside the box, we may overlook important possibilities.”

Light shines onto a solar concentrator being tested in this Aug. 7, 2025, photo. The concentrator is part of the Carbothermal Reduction Demonstration (CaRD) project, which aims to produce oxygen from simulated lunar regolith for use at the Moon’s south pole. For this test, the team integrated the solar concentrator, mirrors, and software and confirmed the production of carbon monoxide.

If deployed on the Moon, this technology could enable the production of propellant using only lunar materials and sunlight, significantly reducing the cost and complexity of sustaining a long-term human presence on the lunar surface. The same downstream systems used to convert carbon monoxide into oxygen can also be adapted to convert carbon dioxide into oxygen and methane on Mars.

The CaRD project was funded by NASA’s Game Changing Development Program, which advances technologies for the agency’s future space missions and solutions to significant national needs.

Nestled in the Mojave Desert, NASA’s Armstrong Flight Research Center in Edwards, California, pushes the boundaries of flight to advance the agency’s aeronautics mission. This is where Chuck Yeager broke the sound barrier and engineers are now pioneering the future of high-speed, autonomous, and electrified aircraft. Armstrong contributes to NASA’s broader mission of innovation and collaboration, leveraging its uniquely capable location.

The story begins in 1947, when 13 engineers and technicians from NASA’s predecessor, the National Advisory Committee for Aeronautics, arrived at Muroc Army Airfield – now Edwards Air Force Base – in Southern California’s high desert to establish the Station for High-Speed Research. Their mission was to prepare for the first supersonic research flights of the X-1 rocket plane. The Bell X-1 became the first aircraft to fly faster than the speed of sound in level flight, a historic milestone that marked the dawn of a new era in aviation and helped cement Edwards Air Force Base as a cornerstone of NASA’s flight research enterprise.

Today, NASA’s mission continues that tradition, supporting cutting-edge projects in aeronautics like the X-59 quiet supersonic technology aircraft, hypersonic research, and emerging technologies in advanced air mobility, with flight testing led at NASA Armstrong in collaboration with other NASA centers and industry partners.

Why Edwards?

NASA Armstrong’s location at Edwards Air Force Base supports NASA’s flight research that would be difficult or impossible elsewhere, offering unmatched access to the largest secure flight test range in the nation equipped with specialized testing instrumentation. The base spans roughly 470 square miles of mission-critical terrain, including Rogers Dry Lake’s 44-square-mile surface. This range provides extensive restricted airspace enabling safe, complex flight-testing scenarios for NASA teams across multiple programs.

Almost from the start of aeronautical advancements, the region’s natural geography played a critical role. In 1937, nearly all the U.S. Army Air Corp’s fleet conducted maneuvers above Rogers Dry Lake – then known as Muroc Dry Lake – a vast, flat expanse formed by ancient geological processes that serves as a unique emergency landing site. Its hard-packed surface and wide-open area provide a natural safety net for experimental aircraft, offering a margin of safety that’s critical during high-risk missions.

With the U.S. involvement in World War II, the area’s importance grew, bringing additional resources, new facilities, and a focus on research, and experimentation with new aircraft designs. Today, the airspace above the region includes the Bell X-1 Supersonic Corridor, a designated section of restricted airspace within the Edwards test range. This corridor provides a safe, controlled environment for supersonic and transonic flight testing, enabling precision maneuvers at high speeds over the Mojave Desert. Combined with nearly year-round flying weather and low population density, this unique airspace supports uninterrupted flight operations for NASA’s aeronautics programs.

A culture of innovation

NASA’s X-plane legacy is deeply rooted in its history. From the X-1 to the X-59, NASA has developed dozens of X-planes – many flight-tested at Edwards with contributions by Armstrong and other NASA centers. These experimental aircraft were designed to push the boundaries of flight and test new technologies. At Edwards, NASA teams have tested everything from lifting body designs – critical for spacecraft and reentry research – to digital fly-by-wire systems, which have become standard in commercial aviation.

This culture of innovation continues today as NASA’s aeronautics team – leveraging Armstrong’s flight research expertise – advances advanced air mobility, electrified propulsion, and autonomous flight systems. The center’s location and infrastructure enable rapid prototyping and testing, accelerating NASA’s ability to mature next generation aviation technologies.

Partnerships with the U.S. Air Force further strengthen NASA’s capabilities. Shared resources, coordinated airspace management, and joint operations allow NASA researchers to conduct complex missions with support and safety protocols, while collaborating across NASA centers and industry.

Supporting a broad mission portfolio

While Armstrong is best known for experimental aircraft, NASA’s work at Edwards supports a diverse mission portfolio. The center supports Earth science missions, airborne sensor testing, and planetary exploration. Its aircraft – including ER-2 and Gulfstream – carry instruments that study climate, weather, and atmospheric composition, contributing vital data to NASA’s science goals in partnership with agency science teams.

Edwards’ location and infrastructure enable these missions by providing access to high-altitude corridors, stable flying conditions, and the ability to integrate new technologies quickly. Whether it’s testing sensors for Mars exploration or flying over hurricanes to collect data, NASA’s airborne science, supported by Armstrong’s flight operations, advance agency priorities.

Milestones that matter

NASA’s flight research heritage at Edwards includes milestones that have shaped aviation history:

• 1947: Chuck Yeager breaks the sound barrier in the Bell X-1.
• 1960s-70s: Lifting body aircraft tested at Edwards lay the groundwork for the space shuttle. NASA tested the Lunar Landing Research Vehicle at Edwards in the mid-1960s to develop techniques later used by Apollo astronauts.
• 1980s: Digital fly-by-wire systems validated at NASA Armstrong become standard in commercial aviation.
• 2000s and beyond: Two successful flights of a scramjet-powered airplane, the X-43A, at hypersonic speeds – greater than Mach 5, or five times the speed of sound. Autonomous aircraft and drones tested for Earth science and defense applications. The X-59 prepares to demonstrate quiet supersonic flight over land, potentially reshaping commercial aviation.

Each of these achievements reflects NASA collaboration, drawing on location, infrastructure, and culture to deliver agency impact. As aviation enters a new era of fuel savings, autonomy, and accessibility, NASA’s aeronautics team – through flight research at Armstrong and elsewhere – remains steady to test the technologies that will define the future of flight.

Looking ahead

With growing interest in advanced air mobility, high-speed flight research, and new aircraft technologies, NASA’s integrated approach is more critical than ever. NASA Armstrong’s flight test discipline and safety frameworks contribute to agency-wide risk management and systems engineering, supporting NASA’s top priorities – from commercial supersonic technologies to the safety practices that underpin human spaceflight.
