NASA Celebrates Artemis II During Houston Texans Space City Day
NASA’s Johnson Space Center was front and center Jan. 4, 2026, as the Houston Texans faced the Indianapolis Colts during Space City Day at NRG Stadium. Fans watched the Texans win while getting a close look at NASA’s Artemis II mission, the first crewed flight of the Artemis campaign.
The Artemis II mission will send four astronauts—NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with CSA (Canadian Space Agency) astronaut Jeremy Hansen—around the Moon and back to Earth to test Orion spacecraft systems in deep space and help lay the groundwork for future lunar missions.
NASA connected fans with the agency’s next giant leap, reinforcing Space City’s role in shaping the future of human exploration.

NASA and its partners have supported humans continuously living and working in space since November 2000. A truly global endeavor, the International Space Station has been visited by more than 290 people from 26 countries and a variety of international and commercial spacecraft. The unique microgravity laboratory has hosted more than 4,000 experiments from over 5,000 researchers from 110 countries. The space station also is facilitating the growth of a commercial market in low Earth orbit for research, technology development, and crew and cargo transportation.
After a quarter of century of human presence in orbit, the station remains a symbol of international cooperation and a proving ground for humanity’s next giant leaps to the Moon and, eventually, Mars.
September’s full Moon, the Harvest Moon, is photographed from the space station, placed in between exterior station hardware.NASAThe microgravity environments aboard the space station unlocks discoveries that benefit life on Earth and prepare humans for deep space missions. NASA’s Human Research Program (HRP) works to understand the changes astronauts face aboard the orbital outpost and to develop interventions to keep crews healthy before, during, and after flight.
Astronauts aboard the station exercise for roughly two hours a day to protect bone density, muscle strength, and the cardiovascular system, but the longer they are in microgravity, the harder it can be for the brain and body to readapt to gravity’s pull. After months in orbit, returning astronauts often describe Earth as heavy, loud, and strangely still. Some reacclimate within days, while other astronauts take longer to fully recover.
Through HRP-led studies, scientists track these changes and test solutions—from improved exercise regimens to medical monitoring and nutritional strategies. The results inspire new medical technologies, while teaching scientists how the human body adapts to long-duration spaceflights—knowledge that helps keep astronauts healthy on future missions.
In the Tranquility node of the orbiting laboratory, NASA astronaut Jessica Meir exercises on the Combined Operational Load Bearing External Resistance Treadmill (COLBERT), technically named the Treadmill 2 and abbreviated as T2. NASAThe space station continues to be a critical platform for sharpening skills, technology, and understanding that will prepare humanity to return to the Moon with NASA’s Artemis campaign and journey on to Mars and beyond.
Since space presents an entirely new physical environment with a distinct set of challenges, the orbiting laboratory is uniquely positioned to support research and preparations not possible on Earth. That includes:
- Mastering techniques for basic tasks like drinking water, sleeping, exercising, and handling various materials.
- Developing solutions to microgravity-induced changes to and challenges for the human body.
- Testing reliable technologies and self-sustaining ecosystems necessary for deep space travel, from life support systems to in-orbit agriculture and 3D printing of materials.
- Refining techniques and procedures for data and imagery collection and analysis.
Read more about how the space station has enabled significant strides in our journey farther into the final frontier.
The first decade of the space station was the decade of construction. The second decade moved from initial studies to fully using the orbiting laboratory. Now we are in the decade of results.
With nearly 25 years of experiments conducted aboard the station, more breakthroughs are materializing than ever before. These scientific discoveries and technological advancements are benefiting humanity on the ground, contributing to the growing low Earth orbit economy, and helping to prepare for future exploration of the Moon and Mars.
Innovations include:
- Advances in X-ray technologies, developed to create a space station telescope, are helping unravel the mysteries of our universe while improving medical devices on Earth.
- Temperature-change data that has been employed in efforts to reduce heat absorbed by city surfaces, reduce fire risk, and help farmers efficiently water their fields.
- Demonstrations of robotic technologies with the potential to relieve repetitive movement and other workplace-related stressors.
- Development of a small ultrasound unit for crew health monitoring that has since been adapted to provide diagnostic care in remote areas on Earth.

Supernova Remnant Video From NASA’s Chandra Is Decades in Making
To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video
A new video shows changes in Kepler’s Supernova Remnant using data from NASA’s Chandra X-ray Observatory captured over more than two and a half decades with observations taken in 2000, 2004, 2006, 2014, and 2025. In this video, which is the longest-spanning one ever released by Chandra, X-rays (blue) from the telescope have been combined with an optical image (red, green, and blue) from Pan-STARRS. X-ray: NASA/CXC/SAO; Optical: Pan-STARRSA new video shows the evolution of Kepler’s Supernova Remnant using data from NASA’s Chandra X-ray Observatory captured over more than two and a half decades.
Kepler’s Supernova Remnant, named after the German astronomer Johannes Kepler, was first spotted in the night sky in 1604. Today, astronomers know that a white dwarf star exploded when it exceeded a critical mass, after pulling material from a companion star, or merging with another white dwarf. This kind of supernova is known as a Type Ia, and scientists use it to measure the expansion of the universe.
Supernova remnants, the debris fields left behind after a stellar explosion, often glow strongly in X-ray light because the material has been heated to millions of degrees from the blast. The remnant is located in our galaxy, about 17,000 light-years from Earth, allowing Chandra to make detailed images of the debris and how it changes with time. This latest video includes its X-ray data from 2000, 2004, 2006, 2014, and 2025. This makes it the longest-spanning video that Chandra has ever released, enabled by Chandra’s longevity.
“The plot of Kepler’s story is just now beginning to unfold,” said Jessye Gassel, a graduate student at George Mason University in Virginia, who led the work. “It’s remarkable that we can watch as these remains from this shattered star crash into material already thrown out into space.” Gassel presented the new Chandra video and the associated research at the 247th meeting of the American Astronomical Society in Phoenix.
The researchers used the video to show that the fastest parts of the remnant are traveling at about 13.8 million miles per hour (2% of the speed of light), moving toward the bottom of the image. Meanwhile, the slowest parts are traveling toward the top at about 4 million miles per hour (0.5% of the speed of light). This large difference in speed is because the gas that the remnant is plowing into toward the top of the image is denser than the gas toward the bottom. This gives scientists information about the environments into which this star exploded.
“Supernova explosions and the elements they hurl into space are the lifeblood of new stars and planets,” said Brian Williams of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and principal investigator of the new Chandra observations of Kepler. “Understanding exactly how they behave is crucial to knowing our cosmic history.”
The team also examined the widths of the rims forming the blast wave of the explosion. The blast wave is the leading edge of the explosion and the first to encounter material outside of the star. By measuring how wide it is and how fast it is traveling, astronomers glean more information about both the explosion of the star and its surroundings.
NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

Visual DescriptionThis release features a ten second silent video of Kepler’s expanding Supernova Remnant, located in our own galaxy, about 17,000 light-years from Earth. The video was created using X-ray data gathered in 2000, 2004, 2006, 2014, and 2025. Those distinct datasets were turned into highly-detailed visuals, creating a 25-year timelapse-style video of the growing remnant.
Kepler’s Supernova Remnant was once a white dwarf star that exploded when it exceeded its critical mass. Here, in X-ray light, the remnant resembles a cloudy neon blue ring with a diagonal cross line stretching from our upper right down to our lower left. The ring appears thinner and wispier at the bottom, with a band of white arching across the top.
As the video plays, cycling through the 5 datasets, the ring subtly, but clearly, expands, like a slowly inflating balloon. In the video, this sequence is replayed several times with dates included at our lower right, to give sighted learners time to absorb the visual information. Upon close inspection, researchers have determined that the bottom of the remnant is expanding fastest; about 13.8 million miles per hour, or 2% of the speed of light. The top of the ring appears to be expanding the slowest; about 4 million miles per hour, or 0.5% of the speed of light. The large difference in speed is because the gas that the remnant is plowing into towards the top of the image is denser than the gas towards the bottom.
Collecting and interpreting this data over decades has provided information about the environment into which the white dwarf star exploded, and has helped scientists understand how remnants change with time.

NASA Marshall Prepares for Demolition of Historic Test, Simulation Facilities
NASA is preparing for the demolition of three iconic structures at the agency’s Marshall Space Flight Center in Huntsville, Alabama.
Crews began demolition in mid-December at the Neutral Buoyancy Simulator, a facility built in the late 1960s that once enabled NASA astronauts and researchers to experience near-weightlessness. The facility was also used to conduct underwater testing of space hardware and practice runs for servicing the Hubble Space Telescope. The simulator was closed in 1997.
Two test stands – the Propulsion and Structural Test Facility and Dynamic Test Facility – are also slated for demolition, one after the other, by carefully coordinated implosion no earlier than sunrise on Jan. 10, 2026.
NASA Marshall tests fires the first stage of the Saturn I rocket at its historic Propulsion and Structural Test Facility, better known as the “T-tower.”The demolition of these historic structures is part of a larger project that began in spring 2022, targeting several inactive structures no longer needed for the agency’s missions. All three towering fixtures played crucial roles in getting humans to the Moon, into low-Earth orbit, and beyond.
These structures have reached the end of their safe, operational life, and their removal has been long-planned as part of a broader effort to modernize Marshall’s footprint. This demolition is the first phase of an initiative that will ultimately remove 25 outdated structures, reduce maintenance burdens, and position Marshall to take full advantage of a guaranteed NASA center infrastructure investment authorized under the Working Families Tax Credit Act.
This work reflects smart stewardship of taxpayer resources.jared isaacman
NASA Administrator
“This work reflects smart stewardship of taxpayer resources,” said NASA Administrator Jared Isaacman. “Clearing outdated infrastructure allows NASA to safely modernize, streamline operations, and fully leverage the infrastructure investments signed into law by President Trump to keep Marshall positioned at the forefront of aerospace innovation.”
Built in 1964, the Dynamic Test Stand initially was used to test fully assembled Saturn V rockets. In 1978, engineers integrated all space shuttle elements for the first time, including the orbiter, external fuel tank, and solid rocket boosters. It was last used in the early 2000s for microgravity testing.
The space shuttle orbiter Enterprise lifted by crane into the Structural Dynamic Test Facility at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for vibration testing in July 1978.NASAThe Propulsion and Structural Test Facility – better known at Marshall as the “T-tower” due to its unique shape – was built in 1957 by the U.S. Army Ballistic Missile Agency and transferred to NASA when Marshall was founded in 1960. There, engineers tested components of the Saturn launch vehicles, the Army’s Redstone Rocket, and shuttle solid rocket boosters. It was last used for space shuttle solid rocket motor tests in the 1990s.
“Each one of these structures helped NASA make history,” said Rae Ann Meyer, acting center director at Marshall. “While it is hard to let them go, they’ve earned their retirement. The people who built and managed these facilities and empowered our mission of space exploration are the most important part of their legacy.”
“These structures are not safe,” continued Meyer. “Strategic demolition is a necessary step in shaping the future of NASA’s mission to explore, innovate, and inspire. By removing these structures that we have not used in decades, we are saving money on upkeep of facilities we can’t use. We also are making these areas safe to use for future NASA exploration endeavors and investments.”
A legacy worth rememberingWhen NASA opened the Neutral Buoyancy Simulator in 1968, it was one of few places on Earth that could recreate the weightlessness of microgravity. The facility provided a simulated zero-gravity environment in which engineers and astronauts could find out how their designs might handle in orbit. The tank has been central to planning and problem-solving for Skylab missions, repairs to NASA’s Hubble Space Telescope, and more. The tank is 75 feet in diameter, 40 feet deep, and designed to hold up to nearly 1.5 million gallons of water. It was replaced in 1997 by a new, larger facility at NASA’s Johnson Space Center in Houston.
Astronaut Kathryn Thornton practices maneuvers planned for the STS-61 mission in the Neutral Buoyancy Simulator at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on Aug. 9, 1993.NASAThe Propulsion and Structural Test Facility is one of the oldest test stands at Marshall. The dual-position test stand, sometimes called the T-tower, was built for static testing large rockets and launch systems – like launching a rocket while keeping it restrained and wired to instruments that collect data. The tests and data played a role in the development of the Saturn family of rockets, including the F-1 engine and S-IC.
The Dynamic Test Stand, a 360-foot tower topped by a 64-foot derrick, was once the tallest human-made structure in North Alabama. Engineers there conducted full-scale tests of Saturn V rockets – the same powerful vehicles that carried Apollo astronauts to the Moon. Later, the stand served as the first location where all space shuttle elements were integrated.
Preserving history for future generationsThe irreplaceable historical value of these landmarks has prompted NASA to undertake extensive efforts to preserve their stories for future generations. The three facilities were made national landmarks in 1985 for their part in human spaceflight. In keeping with Section 106 of the National Historic Preservation Act, master planners and engineers at Marshall completed a rigorous consultation and mitigation process for each landmark, working closely with Alabama’s State Historic Preservation Office to preserve their history for future generations.
Detailed architectural documentation, written histories, and large-format photographs are permanently archived in the Library of Congress’ Historic American Engineering Record collection, making this history accessible to researchers and the public for generations.
Additionally, NASA has partnered with Auburn University to create high-resolution digital models of each facility. The project used technologies like LiDAR and 360-photography of the structures in detail before demolition. Their goal is to preserve not just the appearance, but the sense of scale and engineering achievement they represent. The models are still in work, but they’ll eventually be publicly available.
Select artifacts from the facilities have also been identified and transferred to the U.S. Space & Rocket Center through NASA’s Artifact Program, ensuring tangible pieces of this history remain available for educational purposes.
Honoring the past, building the futureFor the employees, retirees, and community members who remember these facilities over the decades, their removal marks the end of an era. But their contributions live on in every NASA mission, from the International Space Station to the upcoming Artemis II lunar missions and more.
“NASA’s vision of space exploration remains vibrant, and as we look to an exciting future, we honor the past, especially the dedication of the men and women who built these structures and tested hardware that has launched into space, made unprecedented scientific discoveries, and inspired generations of Americans to reach for the stars,” said Meyer.
The demolitions represent more than removing obsolete infrastructure. They’re part of NASA’s commitment to building a dynamic, interconnected campus ready for the next era of space exploration while honoring the bold spirit that has always driven the agency forward.
Virtual tours and preserved documentation will be made available on Marshall’s digital channels. Marshall will also share video of the test stand demolitions after the event.
For communities near Redstone Arsenal, there could be a loud noise associated with the demolition on the morning of Jan. 10.

After combing through NASA’s James Webb Space Telescope’s archive of sweeping extragalactic cosmic fields, a small team of astronomers at the University of Missouri says they have identified a sample of galaxies that have a previously unseen combination of features. Principal investigator Haojing Yan compares the discovery to an infamous oddball in another branch of science: biology’s taxonomy-defying platypus.
“It seems that we’ve identified a population of galaxies that we can’t categorize, they are so odd. On the one hand they are extremely tiny and compact, like a point source, yet we do not see the characteristics of a quasar, an active supermassive black hole, which is what most distant point sources are,” said Yan.
The research was presented in a press conference at the 247th meeting of the American Astronomical Society in Phoenix.
Image A: Galaxies in CEERS Field (NIRCam image) Four of the nine galaxies in the newly identified “platypus” sample were discovered in NASA’s James Webb Space Telescope’s Cosmic Evolution Early Release Science Survey (CEERS). One key feature that makes them distinct is their point-like appearance, even to a telescope that can capture as much detail as Webb. Image: NASA, ESA, CSA, Steve Finkelstein (UT Austin); Image Processing: Alyssa Pagan (STScI)“I looked at these characteristics and thought, this is like looking at a platypus. You think that these things should not exist together, but there it is right in front of you, and it’s undeniable,” Yan said.
The team whittled down a sample of 2,000 sources across several Webb surveys to identify nine point-like sources that existed 12 to 12.6 billion years ago (compared to the universe’s age of 13.8 billion years). Spectral data gives astronomers more information than they can get from an image alone, and for these nine sources it doesn’t fit existing definitions. They are too far away to be stars in our own galaxy, and too faint to be quasars, which are so brilliant that they outshine their host galaxies. Though the spectra resemble the less distant “green pea” galaxies discovered in 2009, the galaxies in this sample are much more compact.
“Like spectra, the detailed genetic code of a platypus provides additional information that shows just how unusual the animal is, sharing genetic features with birds, reptiles, and mammals,” said Yan. “Together, Webb’s imaging and spectra are telling us that these galaxies have an unexpected combination of features.”
Yan explained that for typical quasars, the peaks in their characteristic spectral emission lines look like hills, with a broad base, indicating the high velocity of gas swirling around their supermassive black hole. Instead, the peaks for the “platypus population” are narrow and sharp, indicating slower gas movement.
While there are narrow-line galaxies that host active supermassive black holes, they do not have the point-like feature of the sample Yan’s team has identified.
Image B: Galaxy CEERS 4233-42232: Comparison With Quasar Spectrum This graphic illustrates the pronounced narrow peak of the spectra that caught researchers’ attention in a small sample of galaxies, represented here by galaxy CEERS 4233-42232. Typically, distant point-like light sources are quasars, but quasar spectra have a much broader shape. Illustration: NASA, ESA, CSA, Joseph Olmsted (STScI)Has Yan’s team discovered a missing link in the cosmos? Once the team determined that the objects didn’t fit the definition of a quasar, graduate student researcher Bangzheng Sun analyzed the data to see if there were signatures of star-forming galaxies.
“From the low-resolution spectra we have, we can’t rule out the possibility that these nine objects are star-forming galaxies. That data fits,” said Sun. “The strange thing in that case is that the galaxies are so tiny and compact, even though Webb has the resolving power to show us a lot of detail at this distance.”
One proposal the team suggests is that Webb, as promised, is revealing earlier stages of galaxy formation and evolution than we have ever been able to see before. It is generally accepted across the astronomy community that large, massive galaxies like our own Milky Way grew by many smaller galaxies merging together. But, Yan asks, what comes before small galaxies?
“I think this new research is presenting us with the question, how does the process of galaxy formation first begin? Can such small, building-block galaxies be formed in a quiet way, before chaotic mergers begin, as their point-like appearance suggests?” Yan said.
To begin answering that question, as well as to determine more about the nature of their odd platypuses, the team says they need a much larger sample than nine to analyze, and with higher-resolution spectra.
“We cast a wide net, and we found a few examples of something incredible. These nine objects weren’t the focus; they were just in the background of broad Webb surveys,” said Yan. “Now it’s time to think about the implications of that, and how we can use Webb’s capabilities to learn more.”

Using NASA’s James Webb Space Telescope, astronomers have spotted two rare kinds of dust in the dwarf galaxy Sextans A, one of the most chemically primitive galaxies near the Milky Way. The finding of metallic iron dust and silicon carbide (SiC) produced by aging stars, along with tiny clumps of carbon-based molecules, shows that even when the universe had only a fraction of today’s heavy elements, stars and the interstellar medium could still forge solid dust grains. This research with Webb is reshaping ideas about how early galaxies evolved and developed the building blocks for planets, as NASA explores the secrets of the universe and our place in it.
Sextans A lies about 4 million light-years away and contains only 3 to 7 percent of the Sun’s metal content, or metallicity, the astrophysical term for elements heavier than hydrogen and helium. Because the galaxy is so small, unlike other nearby galaxies, its gravitational pull is too weak to retain the heavy elements like iron and oxygen created by supernovae and aging stars.
Galaxies like it resemble those that filled the early universe just after the big bang, when the universe was made of mostly hydrogen and helium, before stars had time to enrich space with ‘metals.’ Because it is relatively close, Sextans A gives astronomers a rare chance to study individual stars and interstellar clouds under conditions similar to those shortly after the big bang.
“Sextans A is giving us a blueprint for the first dusty galaxies,” said Elizabeth Tarantino, postdoctoral researcher at the Space Telescope Science Institute and lead author of the results in one of the two studies presented at a press conference at the 247th meeting of the American Astronomical Society in Phoenix. “These results help us interpret the most distant galaxies imaged by Webb and understand what the universe was building with its earliest ingredients.”
Image A: Sextans A PAHs Pull-out (NIRCam and MIRI Image) Images from NASA’s James Webb Space Telescope of the dwarf galaxy Sextans A reveal polycyclic aromatic hydrocarbons (PAHs), large carbon-based molecules that can be a signifier of star formation. The inset at the top right zooms in on those PAHs, which are represented in green. Image: NASA, ESA, CSA, Elizabeth Tarantino (STScI), Martha Boyer (STScI), Julia Roman-Duval (STScI); Image Processing: Alyssa Pagan (STScI) Forging dust without usual ingredientsOne of those studies, published in the Astrophysical Journal, honed in on a half a dozen stars with the low-resolution spectrometer aboard Webb’s MIRI (Mid-Infrared Instrument). The data collected shows the chemical fingerprints of the bloated stars very late in their evolution, called asymptotic giant branch (AGB) stars. Stars with masses between one and eight times that of the Sun pass through this phase.
“One of these stars is on the high-mass end of the AGB range, and stars like this usually produce silicate dust. However, at such low metallicity, we expect these stars to be nearly dust-free,” said Martha Boyer, associate astronomer at the Space Telescope Science Institute and lead author in that second companion study. “Instead, Webb revealed a star forging dust grains made almost entirely of iron. This is something we’ve never seen in stars that are analogs of stars in the early universe.”
Silicates, the usual dust formed by oxygen-rich stars, require elements like silicon and magnesium that are almost nonexistent in Sextans A. It would be like trying to bake cookies in a kitchen without flour, sugar, and butter.
A normal cosmic kitchen, like the Milky Way, has those crucial ingredients in the form of silicon, carbon, and iron. In a primitive kitchen, like Sextans A, where almost all of those ingredients are missing, you barely have any proverbial flour or sugar. Therefore, astronomers expected that without those key ingredients, stars in Sextans A couldn’t “bake” much dust at all.
However, not only did they find dust, but Webb showed that one of these stars used an entirely different recipe than usual to make that dust.
The iron-only dust, as well as silicon carbide produced by the less massive AGB stars despite the galaxy’s low silicon abundance, proves that evolved stars can still build solid material even when the typical ingredients are missing.
“Dust in the early universe may have looked very different from the silicate grains we see today,” Boyer said. “These iron grains absorb light efficiently but leave no sharp spectral fingerprints and can contribute to the large dust reservoirs seen in far-away galaxies detected by Webb.”

The discovery means Sextans A is now the lowest-metallicity galaxy ever found to contain PAHs.
But, unlike the broad, sweeping PAH emission seen in metal-rich galaxies, Webb revealed PAHs in tiny, dense pockets only a few light-years across.
“Webb shows that PAHs can form and survive even in the most metal-starved galaxies, but only in small, protected islands of dense gas,” said Tarantino.
The clumps likely represent regions where dust shielding and gas density reach just high enough to allow PAHs to form and grow, solving a decades-long mystery about why PAHs seem to vanish in metal-poor galaxies.
The team has an approved Webb Cycle 4 program to use high-resolution spectroscopy to study the detailed chemistry of Sextans A’s PAH clumps further.

Illustration: NASA, ESA, CSA, STScI, Joseph Olmsted (STScI) Connecting two discoveriesTogether, the results show that the early universe had more diverse dust production pathways than the more established and proven methods, like supernova explosions. Additionally, researchers now know there’s more dust than predicted at extremely low metallicities.
“Every discovery in Sextans A reminds us that the early universe was more inventive than we imagined,” said Boyer. “Clearly stars found a way to make the building blocks of planets long before galaxies like our own existed.”

Space Station Research Informs New FDA-Approved Cancer Therapy
NASA opens the International Space Station for scientists and researchers, inviting them to use the benefits of microgravity for commercial and public research, technology demonstrations, and more. Today, a portion of the crew’s time aboard station is devoted to private industry, including medical research that addresses complex health challenges on Earth and prepares astronauts for future deep space missions.
In collaboration with scientists at Merck, protein crystal growth research on the space station yielded early insights regarding the structure and size of particles best suited for the development of a new formulation of the company’s cancer medicine pembrolizumab for subcutaneous injection. This new route of delivery was approved by the U.S. Food and Drug Administration in September and offers a time-saving alternative to intravenous infusion for certain patients. These research efforts aboard the space station were supported by the ISS National Laboratory.
Originally, the treatment was delivered during an in-office visit via infusion therapy into the patient’s veins, a process that could take up to two hours. Initial delivery improvements reduced infusion times to less than 30 minutes every three weeks. The newly approved subcutaneous injectable form takes about one minute every three weeks, promising to improve quality of life for patients by reducing cost and significantly reducing treatment time for patients and healthcare providers.
UV imaging of a ground control sample (left) and spaceflight sample (right) from Merck’s research shows the much more uniform size and distribution of crystals grown in microgravity. These results helped researchers to refine ground-based production of uniform crystalline suspensions required for an injectable version of the company’s cancer medicine, pembrolizumab.MerckSince 2014, Merck has flown crystal growth experiments to the space station to better understand how crystals form, including the monoclonal antibody used in this cancer treatment. Monoclonal antibodies are lab-made proteins that help the body fight diseases. This research focused on producing crystalline suspensions that dissolve easily in liquid, making it possible to deliver the medication by injection. In microgravity, the absence of gravity’s physical forces allows scientists to grow larger, more uniform, and higher-quality crystals than those grown in ground-based labs, advancing medication development and structural modeling.
Research aboard the space station has provided valuable insights into how gravity influences crystallization, helping to improve drug formulations. The work of NASA and its partners aboard the space station improves lives on Earth, grows a commercial economy in low Earth orbit, and prepares for human exploration of the Moon and Mars.

First Sky Map from NASA’s SPHEREx Observatory
NASA’s SPHEREx Observatory has mapped the entire sky in 102 infrared colors, as seen here in this image released on Dec. 18, 2025. This image features a selection of colors emitted primarily by stars (blue, green, and white), hot hydrogen gas (blue), and cosmic dust (red).
While not visible to the human eye, these 102 infrared wavelengths of light are prevalent in the cosmos, and observing the entire sky this way enables scientists to answer big questions, including how a dramatic event that occurred in the first billionth of a trillionth of a trillionth of a second after the big bang influenced the 3D distribution of hundreds of millions of galaxies in our universe. In addition, scientists will use the data to study how galaxies have changed over the universe’s nearly 14-billion-year history and learn about the distribution of key ingredients for life in our own galaxy.

Diving Into Human Spaceflight Safety with NASA Johnson’s Craig Shannon
Growing up in Houston, Craig Shannon was always inspired by NASA and the spirit of exploration the agency represents. Yet it was a passion for scuba diving that unexpectedly led to his more than 23-year career at NASA’s Johnson Space Center.
Shannon became a certified diver and scuba instructor while earning his bachelor’s degree in communications from Stephen F. Austin State University. He happened to meet divers from NASA’s Neutral Buoyancy Laboratory (NBL) at a local environmental cleanup event during his senior year. “The encounter planted a seed,” he said.

Image courtesy of Craig ShannonShannon was hired as an NBL diver shortly after graduation, launching what would become a 19-year career in dive operations. He progressed through a variety of roles – from utility diver, instructor, and training officer, to dive operations lead, training group lead, and ultimately, dive operations manager. “Each role deepened my understanding of operational excellence, safety, and leadership in high-performance environments,” he said. Shannon added that becoming the dive operations manager was one of the defining points of his career. “I had the privilege of leading an exceptional team and contributing directly to astronaut training and operational excellence.”
Seeking new challenges and opportunities for professional growth, Shannon transitioned to a test safety officer position at Johnson for about four years, expanding his knowledge of technical risk management in different environments. He returned to the NBL in 2025, this time as a safety officer. In that role, Shannon works to protect employees’ well-being and the facility’s operational integrity. His responsibilities are a mix of proactive safety initiatives – such as facility inspections, safety training, and communication – and incident response, which involves investigating mishaps and close calls and developing corrective action plans to prevent recurrence. He also serves as an internal technical consultant, fielding safety-related questions from employees and visitors and providing guidance that complies with Occupational Safety and Health Administration and NASA safety standards.
“I work across functions with operations, engineering, medical, and training teams to integrate safety into all daily processes and long-term planning,” he said. “It brings full circle my commitment to the safety and success of human spaceflight training.”

Shannon has also learned the importance of embracing change. “Change isn’t always easy, but it’s often where the most learning and development happen,” he said. “Whether it was stepping into leadership for the first time, shifting into a new field, or returning to a familiar place with a new purpose, each transition brought growth I never could have anticipated.” He added that patience, accountability, and empathy are important leadership qualities that help build stronger, more resilient teams.
While Shannon takes pride in his work, he said his family is his greatest achievement. “I’m most proud of raising three amazing children with my wife, Kimberley. They have been my grounding force and greatest inspiration,” he said.
Craig Shannon, his wife Kimberley, and their three children enjoy family time at the beach in Florida. Image courtesy of Craig ShannonHe is also the proud co-owner of a local scuba diving company, which allows him to combine his love for diving, travel, and community. “I’ve had the privilege of leading dive trips around the world with groups of amazing people—sharing unforgettable underwater experiences and fostering a strong, adventurous dive community,” he said. “It’s a way for me to stay connected to the roots of my diving career and continue exploring the world through the lens of curiosity and connection.”
He encourages the next generation to find something they are passionate about. “It’s important to be genuinely excited about what you do and to face the challenges ahead with determination and curiosity,” he said. “That energy, paired with a willingness to adapt and grow, has carried me through each phase of my career. Challenges will come, but how you meet them defines your path.”

NASA’s IXPE Measures White Dwarf Star for First Time
By Michael Allen
For the first time, scientists have used NASA’s IXPE (Imaging X-ray Polarization Explorer) to study a white dwarf star. Using IXPE’s unique X-ray polarization capability, astronomers examined a star called the intermediate polar EX Hydrae, unlocking the geometry of energetic binary systems.
In 2024, IXPE spent nearly one week focused on EX Hydrae, a white dwarf star system located in the constellation Hydra, approximately 200 light-years from Earth. A paper about the results published in the Astrophysical Journal. Astrophysics research scientists based at the Massachusetts Institute of Technology in Cambridge led the study, along with co-authors at the University of Iowa, East Tennessee State University, University of Liége, and Embry Riddle Aeronautical University.
A white dwarf star occurs after a star runs out of hydrogen fuel to fuse in its core but is not massive enough to explode as core-collapse supernovae. What remains is very dense, roughly the same diameter as Earth with as much mass as our Sun.
EX Hydrae is in a binary system with a main sequence companion star, from which gas is continuously falling onto the white dwarf. How exactly the white dwarf is accumulating, or accreting, this matter and where it arrives on the white dwarf depends on the strength of the white dwarf star’s magnetic field.
In the case of EX Hydrae, its magnetic field is not strong enough to focus matter completely at the star’s poles. But, it is still rapidly adding mass to the accretion disk, earning the classification “intermediate polars.
In an intermediate polar system, material forms an accretion disk while also being pulled towards its magnetic poles. During this phenomenon, matter reaches tens of millions of degrees Fahrenheit, bouncing off other material bound to the white dwarf star, creating large columns of gas that emit high-energy X-rays – a cosmic situation perfect for IXPE to study.
“NASA IXPE’s one-of-a-kind polarimetry capability allowed us to measure the height of the accreting column from the white dwarf star to be almost 2,000 miles high – without as many assumptions required as past calculations,” said Sean Gunderson, MIT scientist and lead author on the paper. “The X-rays we observed likely scattered off the white dwarf’s surface itself. These features are far smaller than we could hope to image directly and clearly show the power of polarimetry to ‘see’ these sources in detail never before possible.”
Information from IXPE’s polarization data of EX Hydrae will help scientists understand other highly energetic binary systems.
More about IXPEThe IXPE mission, 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. It 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.

NASA announced Monday the selection of industry proposals to advance technologies for the agency’s Habitable Worlds Observatory concept – the first mission that would directly image Earth-like planets around stars like our Sun and study the chemical composition of their atmospheres for signs of life. This flagship space telescope also would enable wide-ranging studies of our universe and support future human exploration of Mars, our solar system, and beyond.
“The Habitable Worlds Observatory is exactly the kind of bold, forward-leaning science that only NASA can undertake,” said NASA Administrator Jared Isaacman. “Humanity is waiting for the breakthroughs this mission is capable of achieving and the questions it could help us answer about life in the universe. We intend to move with urgency, and expedite timelines to the greatest extent possible to bring these discoveries to the world.”
To achieve its science goals, the Habitable Worlds Observatory would need a stable optical system that moves no more than the width of an atom while it conducts observations. The mission also would require a coronagraph – an instrument that blocks the light of a star to better see its orbiting planets – thousands of times more capable than any space coronagraph ever built. The Habitable Worlds Observatory would be designed to allow servicing in space, to extend its lifetime and bolster its science over time.
To further the readiness of these technologies, NASA has selected proposals for three-year, fixed-price contracts from the following companies:
- Astroscale U.S. Inc., Denver
- BAE Systems Space and Mission Systems, Inc., Boulder, Colorado
- Busek Co. Inc, Natick, Massachusetts
- L3Harris Technologies Inc., Rochester, New York
- Lockheed Martin Inc., Palo Alto, California
- Northrop Grumman Inc., Redondo Beach, California
- Zecoat Co. Inc., Granite City, Illinois
“Are we alone in the universe? is an audacious question to answer, but one that our nation is poised to pursue, leveraging the groundwork we’ve laid from previous NASA flagship missions. With the Habitable Worlds Observatory, NASA will chart new frontiers for humanity’s exploration of the cosmos,” said Shawn Domagal-Goldman, director of the Astrophysics Division at NASA Headquarters in Washington. “Awards like these are a critical component of our incubator program for future missions, which combines government leadership with commercial innovation to make what is impossible today rapidly implementable in the future.”
The newly selected proposals build on previous industry involvement, which began in 2017 under NASA’s “System-Level Segmented Telescope Design” solicitations and continued with awards for large space telescope technologies in 2024. The newly selected proposals will help inform NASA’s approach to planning for the Habitable Worlds Observatory concept, as the agency builds on technologies and lessons learned from its Hubble Space Telescope, James Webb Space Telescope, and upcoming Nancy Grace Roman Space Telescope.

What’s Up: January 2026 Skywatching Tips from NASA
Jupiter is at its biggest and brightest all year, the Moon and Saturn pair up, and the Beehive Cluster buzzes into view.
Skywatching Highlights- Jan. 10: Jupiter at opposition
- Jan. 23: Saturn and Moon conjunction
- Jan. (throughout): Beehive Cluster
Jupiter is at its biggest and brightest
The Moon and Saturn share the sky
And the beehive cluster makes an appearance
That’s what’s up, this January
January 10, Jupiter will be at its most brilliant of the entire year!
This night, Jupiter will be at what’s called “opposition,” meaning that Earth will be directly between Jupiter and the Sun.
NASA/JPL-CaltechIn this alignment, Jupiter will appear bigger and brighter in the night sky than it will all year – talk about starting off the new year bright!
To see Jupiter at its best this year, look to the east and all evening long, you’ll be able to see the planet in the constellation Gemini. It will be one of the brightest objects in the night sky (only the moon and Venus will be brighter)
Saturn and the Moon will share the sky on January 23rd as part of a conjunction!
NASA/JPL-CaltechA conjunction is when objects in the sky look close together even though they’re actually far apart.
To spot the pair, look to the west and you’ll see Saturn just below the moon, sparkling in the night sky.
The beehive cluster will be visible in the night sky throughout January!
The beehive cluster, more formally known as Messier 44, or M44, is made of at least 1,000 stars
It’s an open star cluster, meaning it’s a loosely-bound group of stars. There are thousands of open star clusters like the beehive in the Milky Way Galaxy!
NASA/JPL-CaltechTo see the beehive cluster, look to the eastern night sky after sunset and before midnight throughout the month – especially great nights to spot the cluster are around the middle of January when the cluster isn’t too high or low in the sky to see.
With dark skies you might be able to spot the beehive with just your eyes, but binoculars or a small telescope will help.
Here are the phases of the Moon for January.
