As NASA returns astronauts to the Moon through the agency’s Artemis campaign in advance of human exploration of Mars, researchers at Langley are exploring technology that could significantly reduce travel time to the Red Planet. Modular Assembled Radiators for Nuclear Electric Propulsion Vehicles, or MARVL, would use robots for in-space assembly of elements needed to enable nuclear electric propulsion of future spacecraft, which could transform travel to deep space. 

NASA Cameras Catch First-of-its-Kind Moon Close-up 

The Moon was ready for its close-up in March, when cameras developed by a Langley team captured first-of-its-kind imagery of a lunar lander’s engine plumes interacting with the Moon’s surface during Firefly Aerospace’s Blue Ghost Mission 1. Information gathered from images like this is critical in helping NASA prepare for future crewed and uncrewed lunar landings.

One of the most challenging tasks in remote sensing from space is achieving required instrument calibration on-orbit. Langley scientists are addressing the challenge head on through the Arcstone mission, an instrument that launched in June and aims to establish the Moon as a cost-efficient, high-accuracy calibration reference. Once established, the new standard can be applied to past, present, and future spaceborne sensors and satellite constellations. Arcstone uses a spectrometer, a scientific instrument that measures and analyzes light, to measure lunar spectral reflectance.  

NASA Mission Continues Monitoring Air We Breathe 

By measuring nitrogen dioxide (NO2) and formaldehyde (HCHO), TEMPO can derive the presence of near-surface ozone. On Aug. 2, 2024 over Houston, TEMPO observed exceptionally high ozone levels in the area. On the left, NO2 builds up in the atmosphere over the city and over the Houston Ship Channel. On the right, formaldehyde levels are seen reaching a peak in the early afternoon. Formaldehyde is largely formed through the oxidation of hydrocarbons, an ingredient of ozone production, such as those that can be emitted by petrochemical facilities found in the Houston Ship Channel.
NASA’s Scientific Visualization Studio

The success of NASA’s Tropospheric Emissions: Monitoring of Pollution mission, or TEMPO, earned the mission an extension, meaning the work to monitor Earth’s air quality from 22,000 miles above the ground will continue through at least September 2026. The Langley-led mission launched in 2023 and is NASA’s first to use a spectrometer, a scientific instrument that measures and analyzes light, to gather hourly air quality data continuously over North America during daytime hours. The data gathered is distributed freely to the public, giving air quality forecasters, scientists, researchers, and your next-door neighbor access to quality information about the air we breathe down to the neighborhood level.

 NASA’s Athena Economical Payload Integration Cost mission, or Athena EPIC, launched in July with the goal to shape a future path to launch that saves taxpayers money and expedites access to space. Athena EPIC was the first NASA-led mission led to utilize HISat technology, small satellites engineered to aggregate, share resources, and conform to different sizes and shapes. Langley’s scientists designed and built the Athena sensor with spare parts from NASA’s CERES (Clouds and the Earth’s Radiant Energy System) mission to gather top of atmosphere measurements. Athena EPIC demonstrates a novel way to launch Earth-observing instruments into orbit quicker and more economically. 

Drop Test at Langley Offers Research, Data for Potential Air Taxi Designs  

The future of air travel includes the safe integration of drones and air taxis into our airspace for passenger transport, cargo delivery, and public service capabilities. That is why NASA is investigating and testing potential air taxi materials and designs to help the aviation industry better understand how those materials behave under impact. Data collected from a drop test at Langley’s Landing and Impact Research Facility in June will help in the development of safety regulations for advanced air mobility aircraft, leading to safer designs.    

Langley Wind Tunnel Tests Help Support Advanced Air Mobility Aircraft Development

The lack of publicly available engineering and flight data to help address technical barriers in the design and development of new electric vertical takeoff and landing (eVTOL) aircraft is a challenge for researchers and engineers. That is why Langley researchers are using a research aircraft that provides real-world data, obtained through wind tunnel and flight tests, to help fill the information gap and check the accuracy of computer models for flight dynamics and controls. Making this data available to all is a key step in transforming the way we fly and safely integrating new aircraft into our nation’s airspace.

A material from NASA Langley is riding high as it orbits the Earth aboard a United States Space Force test vehicle, giving researchers a better understanding of how the material responds to long-duration exposure to the harsh vacuum of space. The strap material is a part of a Langley-developed aeroshell to protect spacecraft re-entering Earth’s atmosphere or to ensure their safe landing on other celestial bodies, such as Mars. Understanding how extended exposure to space affects the material is important as NASA prepares to send humans beyond the Moon.

Data gathered during a Langley-led airborne science campaign late this summer could help protect air travelers on Earth and future space travelers to the Moon, Mars, and beyond from the health risks associated with radiation exposure. NASA’s Space Weather Aviation Radiation (SWXRAD) aircraft flight campaign took place in Greenland and measured the radiation dose level to air travelers from cosmic radiation. Researchers are using the information to enhance a modeling system that offers real-time global maps of the hazardous radiation in the atmosphere and creates exposure predictions for aircraft and spacecraft.

As NASA returns astronauts to the Moon through the Artemis campaign in preparation for human exploration of Mars, the agency also has its sights set on Saturn, specifically Saturn’s moon Titan. NASA’s Dragonfly, a car-sized rotorcraft set to launch no earlier than 2028, will explore Titan and try to discover how life began. This fall, engineers placed a full-scale test model representing half of the Dragonfly lander in Langley’s Transonic Dynamics Tunnel to evaluate how its rotor system performed in Titan-like conditions. The data will be integral in developing the rotorcraft’s flight plans and navigation software as it investigates multiple landing sites on Titan.

In response to severe weather that impacted more than 10 states in November, the NASA Disasters Response Coordination System (DRCS) activated to support national partners. The DRCS is headquartered at Langley. NASA worked closely with the National Weather Service and the Federal Emergency Management Agency serving the central and southeastern U.S. to provide satellite data and expertise that help communities better prepare, respond, and recover. 

NASA’s X-59 Takes Flight 

In October, NASA’s Quesst mission celebrated a major milestone – the X-59 quiet supersonic one-of-a-kind research aircraft flew for the first time, a historic moment for aviation. The hard work, talent, and innovation of NASA engineers and project team members, including many based at NASA Langley, made this achievement possible. One of the notable traits of the X-59 is the eXternal Vision System (XVS) which allows the test pilots to safely maneuver the skies without a forward-facing window. This unique supersonic design feature was developed and tested at NASA Langley. 

The X-59’s first flight was a major step toward quiet supersonic flight over land, which could revolutionize air travel.

A Siberian Snowman in Billings

A Siberian Snowman in Billings

A Landsat image of Russia’s Chukchi Peninsula shows a narrow coastal sandspit separating the Arctic Ocean from a chain of elongated, ice-covered coastal lagoons near the village of Billings and Cape Billings. The pale blue lagoons vary in size and line up end-to-end, creating a shape that resembles a snowman pressed against the shoreline. Offshore, fractured sea ice forms a bright, textured band along the coast, while darker tundra and thermokarst lakes extend inland.
June 16, 2025

Icons of winter are sometimes found in unexpected places. In one striking example, a series of oval lagoons in a remote part of Siberia forms the shape of a towering snowman when viewed from above.

This image, centered on the remote village of Billings and nearby Cape Billings on Russia’s Chukchi Peninsula, was captured by the OLI (Operational Land Imager) aboard Landsat 8 on June 16, 2025. Established in the 1930s as a port and supply point for the Soviet Union, the village sits on a narrow sandspit that separates the Arctic Ocean from a series of connected coastal inshore lagoons.

The elongated, oval lagoons are frozen over and flanked by sea ice. Though June is one of the warmest months in Billings, ice cover is routine even then. Mean daily minimum temperatures are just minus 0.6 degrees Celsius (30.9 degrees Fahrenheit) in June, according to meteorological data.   

Though the shape may seem engineered, it is natural and the product of geological processes common in the far north. The ground in this part of Siberia is frozen most of the year and pockmarked with spear-shaped ice wedges buried under the surface. Summer melting causes overlying soil to slump, leaving shallow depressions that fill with meltwater and form thermokarst lakes. Once created, consistency in the direction of the winds and waves likely aligned and elongated the lakes into the shapes seen in the image. The thin ridges separating the lakes may represent the edges of different ice wedges below the surface.

The first reference to humans building snowmen dates back to the Middle Ages, according to the book The History of the Snowman. While three spherical segments are the most common form, other variants dominate in certain areas. In Japan, snowmen typically have just two segments and are rarely given arms. This five-segmented snowman-shaped series of lakes spans about 22 kilometers (14 miles) from top to bottom, making it roughly 600 times longer than the actual snowwoman that held the Guinness record for being the world’s tallest snowperson in 2025.

Snowmen are not the only winter icons tied to this remote landscape. For early expeditions to the Russian Arctic, reindeer offered one of the most reliable modes of transportation. That includes expeditions by the town’s namesake, Commodore Joseph Billings, a British-born naval officer who enlisted in the Russian navy and led a surveying expedition to find a Northeast Passage between 1790 and 1794.

Although the hundred-plus members of the expedition did not reach Cape Billings, they explored much of the Chukchi Peninsula, producing some of the first accurate maps and further confirming that Asia and North America were separated by a strait. In the winter months, when their ships were beset by ice, the explorers moved to temporary camps on land and instead surveyed the region with reindeer-drawn wooden sleds, according to historical accounts. Winters, in fact, offered the best conditions for exploration because the peninsula’s many rivers and lakes turned into solid surfaces that were easy to traverse in comparison to the muddy bogs that open up in the summer.

Indigenous Chukchi people living on the peninsula at the time routinely used reindeer to haul both people and cargo. A pair of reindeer can comfortably haul hundreds of pounds for several hours a day. In addition to their impressive endurance in cold temperatures, reindeer largely feed themselves by digging through snow and grazing on lichens, something that neither sled dogs nor horses can do.

Historical documents indicate that the Billings expedition enlisted Chukchi people to manage and care for the reindeer they used, with some accounts suggesting that the explorers used dozens of reindeer at times. While reindeer were mainly used to haul sleds, Chukchi people likely rode them as well.

Non-Chukchi members of the expedition reportedly experimented with riding reindeer, though their experiments did not always go smoothly. Billings’ secretary and translator Martin Sauer reported using a saddle without stirrups or a bridle and falling “nearly 20 times” after about three hours of travel in his account of the expedition. Not only that, he added, but the saddle “at first, causes astonishing pain to the thighs.”

Stem cell research, a student robotics challenge, and spacesuit maintenance dominated the schedule aboard the International Space Station on Tuesday. The Expedition 74 crew also rounded out its shift with Earth observations and cargo transfers throughout the day.

Repairing damaged organs or tissues is a key objective for a technology demonstration taking place onboard the orbital outpost that seeks to transform stem cells into any human cell type that are superior to those manufactured on Earth. The stem cells are reprogrammed from adult skin or blood cells and may lead to advances in regenerative medicine and cancer therapies. Station Commander Mike Fincke treated samples for the stem cell tech demo inside the Kibo laboratory module’s Life Science Glovebox then prepared them for preservation in cold stowage. The experiment hardware and research samples were launched to the station in October aboard JAXA’s (Japan Aerospace Exploration Agency) HTV-X1 cargo craft.

JAXA Flight Engineer Kimiya Yui spent his shift testing a pair of small robotic helpers ahead of an upcoming student challenge to program and maneuver the free-flying devices on the station. The main objective was a technical rehearsal of the toaster-sized Astrobee’s ability to identify and find hidden objects throughout the Kibo lab. The second objective was to monitor the Int-Ball 2, a small sphere-shaped robotic camera designed by JAXA, as it autonomously worked alongside Astrobee and recorded its search activities. Code written by student teams will operate the two robots together and will be judged for its accuracy, speed, and efficiency.

NASA Flight Engineers Zena Cardman and Chris Williams partnered together during the first half of their shift on Tuesday and resized a pair of spacesuits inside the Quest airlock. The duo adjusted the suits’ arms, legs, and waist ahead of a pair of maintenance spacewalks planned for early 2026. Afterward, Cardman moved on and cleaned and inspected hatch seals throughout the space station’s U.S. segment. Williams assisted Fincke and Yui during the second half of their shift as they loaded the HTV-X1 cargo craft with obsolete science hardware before the resupply ship’s departure in late January.

Roscosmos cosmonauts Oleg Platonov and Sergei Mikaev took part in a pair of Earth observation activities documenting the effects of natural and man-made conditions on the ground. Platonov turned off and uninstalled imagery hardware that automatically photographed landmarks from Asia to Africa during the crew’s sleep shift. Mikaev set up a digital multi-spectral camera linked to hardware that automatically operates and aligns the camera to target specific locations on Earth.

Roscosmos Flight Engineer Sergey Kud-Sverchkov, on his second spaceflight, spent Tuesday inside the Nauka science module cleaning smoke detectors ensuring the safety gear operates in tip-top shape. Kud-Sverchkov also spent a few moments with his cosmonaut crewmates Platonov and Mikaev reviewing procedures for unlikely emergency events such as a depressurization, a chemical leak, or a fire onboard the orbital outpost.

Written by Michael Allen

An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) has identified the origin of X-rays in a supermassive black hole’s jet, answering a question that has been unresolved since the earliest days of X-ray astronomy. Their findings are described in a paper published in The Astrophysical Journal Letters, by the American Astronomical Society, Nov. 11.

The IXPE mission observed the Perseus Cluster, the brightest galaxy cluster i observable in X-rays, for more than 600 hours over a 60-day period between January and March. Not only is this IXPE’s longest observation of a single target to date, it also marks IXPE’s first time observing a galaxy cluster.

Specifically, the team of scientists studied the polarization properties of 3C 84, the massive active galaxy located at the very center of the Perseus Cluster. This active galaxy is a well-known X-ray source and a common target for X-ray astronomers because of its proximity and brightness.

Because the Perseus Cluster is so massive, it hosts an enormous reservoir of X-ray emitting gas as hot as the core of the Sun. The use of multiple X-ray telescopes, particularly the high-resolution imaging power of NASA’s Chandra X-ray Observatory was essential to disentangle the signals in the IXPE data. Scientists combined these X-ray measurements with data from the agency’s Nuclear Spectroscopic Telescope Array (NuSTAR) mission and Neil Gehrels Swift Observatory.

Fast facts

  • Polarization measurements from IXPE carry information about the orientation and alignment of emitted X-ray light waves. The more X-ray waves traveling in sync, the higher the degree of polarization.
  • X-rays from an active galaxy like 3C 84 are thought to originate from a process known as inverse Compton scattering, where light bounces off particles and gains energy. The polarization measurements from IXPE allow us to identify the presence of either inverse Compton scattering or other scenarios.
  • “Seed photons” is the term for the lower-energy radiation undergoing the energizing process of inverse Compton scattering.
  • You may remember the Perseus Cluster from this sonification replicating what a Black Hole sounds like from May 2022.

“While measuring the polarization of 3C 84 was one of the key science goals, we are still searching for additional polarization signals in this galaxy cluster that could be signatures of more exotic physics,” said Steven Ehlert, project scientist for IXPE and astronomer at NASA’s Marshall Space Flight Center in Huntsville.

“We’ve already determined that for sources like 3C 84, the X-rays originated from inverse Compton scattering,” said Ioannis Liodakis, a researcher at the Institute of Astrophysics – FORTH in Heraklion, Greece, and lead author on the paper. “With IXPE observations of 3C 84 we had a unique chance to determine the properties of the seed photons.”

The first possible origin scenario for the seed photons is known as synchrotron self-Compton, where lower-energy radiation originates from the same jet that produces the highly energetic particles.

In the alternative scenario known as external Compton, seed photons originate from background radiation sources unrelated to the jet.

“The synchrotron self-Compton and external Compton scenarios have very different predictions for their X-ray polarization,” said Frederic Marin, an astrophysicist at the Strasbourg Astronomical Observatory in France and co-author of the study. “Any detection of X-ray polarization from 3C 84 almost decisively rules out the possibility of external Compton as the emission mechanism.”

Throughout the 60-day observation campaign, optical and radio telescopes around the world turned their attention to 3C 84 to further test between the two scenarios.

NASA’s IXPE measured a net polarization of 4% in the X-rays spectrum, with comparable values measured in the optical and radio data. These results strongly favor the synchrotron self-Compton model for the seed photons, where they come from the same jet as the higher-energy particles.

“Separating these two components was essential to this measurement and could not be done by any single X-ray telescope, but by combining the IXPE polarization data with Chandra, NuSTAR, and Swift, we were able to confirm this polarization measurement was associated specifically with 3C 84,” said Sudip Chakraborty, a researcher at the Science and Technology Institute of the Universities Space Research Association in Huntsville, Alabama, and co-author on the paper.

Scientists will continue to analyze IXPE’s data from different locations in the Perseus Cluster for different signals.

More about IXPE

NASA’s 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. The IXPE mission is led by NASA’s Marshall Space Flight Center in Huntsville, Alabama. BAE Systems, Inc., headquartered in Falls Church, Virginia, manages spacecraft operations together with the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder.
