For more than a decade, Tristan McKnight has been a driving force behind some of NASA’s most iconic events, orchestrating the behind-the-scenes magic that brings each historic moment to life while sharing the agency’s advancements with the public. 

As a multimedia producer on the audiovisual team at Johnson Space Center in Houston, McKnight produces and directs live broadcasts and manages event planning, coordination, and execution. From overseeing resources, mitigating risks, and communicating with stakeholders, he ensures every detail aligns seamlessly.  

McKnight has played an integral role in the audiovisual team’s coverage of major events including the Artemis II crew announcement, where NASA revealed the astronauts who will venture around the Moon and back, to Johnson’s 2023 Open House, which celebrated the agency’s 65th anniversary and the 25th anniversary of the International Space Station’s operations. These achievements highlight key milestones in human space exploration.  

A standout achievement was contributing to the Dorothy Vaughan Center in Honor of the Women of Apollo naming ceremony, held on the eve of the 55th anniversary of the Apollo 11 Moon landing. The event honored the unsung heroes who made humanity’s first steps on the Moon possible. 

The team’s dedication and passion are a testament to their commitment to sharing NASA’s legacy with the world. 

“Not only have these events been impactful to Johnson, but they have also resonated across the entire agency,” McKnight said. “That is what I’m most proud of!” 

One of McKnight’s most memorable events was the 2023 “Back in the Saddle,” an annual tradition designed to refocus Johnson’s workforce at the start of a new year and renew the center’s commitment to safety and mission excellence. McKnight recalled how the speaker transformed Johnson’s Teague Auditorium into a venue filled with drum kits, inspiring messages, and lighting displays. Each audience member, drumsticks in hand, participated in a lesson on teamwork and synchronization to create a metaphor for working in harmony toward a shared goal. 

Like many high-achieving professionals. McKnight has faced moments of self-doubt. Then he realized that he is exactly where he is supposed to be. “As I settled into my role, I recognized that my contributions matter and simply being true to who I am adds value to the Johnson community,” he said.  

Each day brings its own set of challenges, ranging from minor issues like communication gaps and scheduling conflicts to major obstacles like technology failures. One of McKnight’s most valuable lessons is recognizing that there is no one-size-fits-all solution, and each situation requires a thoughtful analysis. 

McKnight understands the importance of the “check-and double-check,” a philosophy he considers crucial when working with technology. “Taking the extra time to do your due diligence, or even having someone else take a look, can make all the difference,” he said. 

“The challenges I’ve faced helped me grow as a problem solver and taught me valuable lessons on resilience and adaptability in the workplace,” he said. McKnight approaches obstacles with a level head, focusing on effective solutions rather than dwelling on the problem. 

As humanity looks to the stars, McKnight is energized about the future of exploration, particularly advancements in spacesuit and rocket technology that will enable us to travel farther, faster, and safer than ever before. His work, though grounded on Earth, helps create the inspiration that fuels these bold endeavors. 

“My hope for the next generation is that they dive deeper into their curiosity—exploring not only the world around them but also the Moon, planets, and beyond,” he said. “I also hope they carry forward the spirit of resilience and a commitment to making the world a better place for all.” 

The Kennedy Center, previously operated by the elites in Washington, DC, is "broke" due in part to bloated executive salaries, a source inside the Center told Breitbart News.

In Aug. 2024, a team of NASA researchers and partners gathered in Missoula, to test new drone-based technology for localized forecasting, or micrometeorology. Researchers attached wind sensors to a drone, NASA’s Alta X quadcopter, aiming to provide precise and sustainable meteorological data to help predict fire behavior.

Wildfires are increasing in number and severity around the world, including the United States, and wind is a major factor. It leads to unexpected and unpredictable fire growth, public threats, and fire fatalities, making micrometeorology a very effective tool to combat fire.

The campaign was run by NASA’s FireSense project, focused on addressing challenges in wildland fire management by putting NASA science and technology in the hands of operational agencies.

“Ensuring that the new technology will be easily adoptable by operational agencies such as the U.S. Forest Service and the National Weather Service was another primary goal of the campaign,” said Jacquelyn Shuman, FireSense project scientist at NASA’s Ames Research Center in California’s Silicon Valley.

The FireSense team chose the Alta X drone because the U.S. Forest Service already has a fleet of the quadcopters and trained drone pilots, which could make integrating the needed sensors – and the accompanying infrastructure – much easier and more cost-effective for the agency.

The choice of the two sensors for the drone’s payload was also driven by their adoptability.

The first, called a radiosonde, measures wind direction and speed, humidity, temperature, and pressure, and is used daily by the National Weather Service. The other sensor, an anemometer, measures wind speed and direction, and is used at weather stations and airports around the world.

“Anemometers are everywhere, but are usually stationary,” said Robert McSwain, the FireSense uncrewed aerial system (UAS) lead, based at NASA’s Langley Research Center in Hampton, Virginia. “We are taking a sensor type that is already used all over the world, and giving it wings.”

Both sensors create datasets that are already familiar to meteorologists worldwide, which opens up the potential applications of the platform.

Current Forecasting Methods: Weather Balloons

Traditionally, global weather forecasting data is gathered by attaching a radiosonde to a weather balloon and releasing it into the air. This system works well for regional weather forecasts. But the rapidly changing environment of wildland fire requires more recurrent, pinpointed forecasts to accurately predict fire behavior. It’s the perfect niche for a drone.

“These drones are not meant to replace the weather balloons,” said Jennifer Fowler, FireSense’s project manager at Langley. “The goal is to create a drop-in solution to get more frequent, localized data for wildfires – not to replace all weather forecasting.”

Drones Provide Control, Repeat Testing, Sustainability

Drones can be piloted to keep making measurements over a precise location – an on-site forecaster could fly one every couple of hours as conditions change – and gather timely data to help determine how weather will impact the direction and speed of a fire.

Fire crews on the ground may need this information to make quick decisions about where to deploy firefighters and resources, draw fire lines, and protect nearby communities.

A reusable platform, like a drone, also reduces the financial and environmental impact of forecasting flights. 

“A weather balloon is going to be a one-off, and the attached sensor won’t be recovered,” Fowler said. “The instrumented drone, on the other hand, can be flown repeatedly.”

The Missoula Campaign

Before such technology can be sent out to a fire, it needs to be tested. That’s what the FireSense team did this summer.

McSwain described the conditions in Missoula as an “alignment of stars” for the research: the complex mountain terrain produces erratic, historically unpredictable winds, and the sparsity of monitoring instruments on the ground makes weather forecasting very difficult. During the three-day campaign, several fires burned nearby, which allowed researchers to test how the drones performed in smokey conditions.

A drone team out of NASA Langley conducted eight data-collection flights in Missoula. Before each drone flight, student teams from the University of Idaho in Moscow, Idaho, and Salish Kootenai College in Pablo, Montana, launched a weather balloon carrying the same type of radiometer.

Once those data sets were created, they needed to be transformed into a usable format. Meteorologists are used to the numbers, but incident commanders on an active fire need to see the data in a form that allows them to quickly understand which conditions are changing, and how. That’s where data visualization partners come in. For the Missoula campaign, teams from MITRE, NVIDIA, and Esri joined NASA in the field.

Measurements from both the balloon and the drone platforms were immediately sent to the on-site data teams. The MITRE team, together with NVIDIA, tested high-resolution artificial intelligence meteorological models, while the Esri team created comprehensive visualizations of flight paths, temperatures, and wind speed and direction. These visual representations of the data make conclusions more immediately apparent to non-meteorologists.

What’s Next?

Development of drone capabilities for fire monitoring didn’t begin in Missoula, and it won’t end there.

“This campaign leveraged almost a decade of research, development, engineering, and testing,” said McSwain. “We have built up a UAS flight capability that can now be used across NASA.”

The NASA Alta X and its sensor payload will head to Alabama and Florida in spring 2025, incorporating improvements identified in Montana. There, the team will perform another technology demonstration with wildland fire managers from a different region.

The FireSense project is led by NASA Headquarters in Washington and sits within the Wildland Fires program, with the project office based at NASA Ames. The goal of FireSense is to transition Earth science and technological capabilities to operational wildland fire management agencies, to address challenges in U.S. wildland fire management before, during, and after a fire. 

NASA’s Artemis campaign will send astronauts, payloads, and science experiments into deep space on NASA’s SLS (Space Launch System) super heavy-lift Moon rocket. Starting with Artemis IV, the Orion spacecraft and its astronauts will be joined by other payloads atop an upgraded version of the SLS, called Block 1B. SLS Block 1B will deliver initial elements of a lunar space station designed to enable long term exploration of the lunar surface and pave the way for future journeys to Mars. To fly these advanced payloads, engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are building a cone-shaped adapter that is key to SLS Block 1B.

The payload adapter, nestled within the universal stage adapter sitting atop the SLS Block 1B’s exploration upper stage, acts as a connecting point to secure a large payload that is co-manifested – or flying along with – the Orion spacecraft. The adapter consists of eight composite panels with an aluminum honeycomb core and two aluminum rings.

Beginning with the Artemis IV mission, SLS Block 1B will feature a new, more powerful upper stage that provides a substantial increase in payload mass, volume, and energy over the first variant of the rocket that is launching Artemis missions I through III. SLS Block 1B can send 84,000 pounds of payload – including both a crewed Orion spacecraft and a 10-metric ton (22,046 lbs.) co-manifested payload riding in a separate cargo compartment – to the Moon in a single launch.

Artemis IV’s co-manifested payload will be the Lunar I-Hab, one of the initial elements of the Gateway lunar space station. Built by ESA (European Space Agency), the Lunar I-Hab provides expanded capability for astronauts to live, work, conduct science experiments, and prepare for their missions to the lunar surface.

Before the Artemis IV mission structure was finalized, NASA engineers needed to design and test the new payload adapter.

“With SLS, there’s an intent to have as much commonality between flights as possible,” says Brent Gaddes, Lead for the Orion Stage Adapter and Payload Adapter in the SLS Spacecraft/Payload Integration & Evolution Office at NASA Marshall.

However, with those payloads changing typically every flight, the connecting payload adapter must change as well.

“We knew there needed to be a lot of flexibility to the payload adapter, and that we needed to be able to respond quickly in-house once the payloads were finalized,” says Gaddes.

A Flexible Approach

The required flexibility was not going to be satisfied with a one-size-fits-all approach, according to Gaddes.

Since different size payload adapters could be needed, Marshall is using a flexible approach to assemble the payload adapter that eliminates the need for heavy and expensive tooling used to hold the parts in place during assembly.  A computer model of each completed part is created using a process called structured light scanning. The computer model provides the precise locations where holes need to be drilled to hold the parts together so that the completed payload adapter will be exactly the right size.

“Structured light has helped us reduce costs and increase flexibility on the payload adapter and allows us to pivot,” says Gaddes. “If the call came down to build a cargo version of SLS to launch 40 metric tons, for example, we can use our same tooling with the structured light approach to adapt to different sizes, whether that’s for an adapter with a larger diameter that’s shorter, or one with a smaller diameter that’s longer. It’s faster and cheaper.”  

NASA Marshall engineers use an automated placement robot to manufacture eight lightweight composite panels from a graphite epoxy material. The robot performs fast, accurate lamination following preprogrammed paths, its high speed and precision resulting in lower cost and significantly faster production than other manufacturing methods.

At NASA Marshall, an engineering development unit of the payload has been successfully tested which demonstrated that it can handle up to three times the expected load. Another test version currently in development, called the qualification unit, will also be tested to NASA standards for composite structures to ensure that the flight unit will perform as expected.

“The payload adapter is shaped like a cone, and historically, most of the development work on structures like this has been on cylinders, so that’s one of the many reasons why testing it is so important,” says Gaddes. “NASA will test as high a load as possible to learn what produces structural failure. Any information we learn here will feed directly into the body of information NASA has pulled together over the years on how to analyze structures like this, and of course that’s something that’s shared with industry as well. It’s a win for everybody.”

With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

When NASA’s Artemis IV astronauts journey to the Moon, they will make the inaugural visit to Gateway, humanity’s first space station in lunar orbit. Shown here, technicians carefully guide HALO (Habitation and Logistics Outpost)—a foundational element of Gateway—onto a stand in the cleanroom at Thales Alenia Space in Turin, Italy. The element’s intricate structure, designed to support astronauts and science in lunar orbit, has entered the cleanroom after successfully completing a series of rigorous environmental stress tests.

In the cleanroom, technicians will make final installations before preparing the module for transport to the United States, a key milestone on its path to launch. This process includes installing and testing valves and hatches, performing leak checks, and integrating external secondary structures. Once these steps are finished, the module will be packaged for shipment to Gilbert, Arizona, where Northrop Grumman will complete its outfitting.

As one of Gateway’s four pressurized modules, HALO will provide Artemis astronauts with space to live, work, conduct scientific research, and prepare for missions to the lunar surface. The module will also support internal and external science payloads, including a space weather instrument suite attached via a Canadian Space Agency Small Orbital Replacement Unit Robotic Interface, host the Lunar Link communications system developed by European Space Agency, and offer docking ports for visiting vehicles, including lunar landers and NASA’s Orion spacecraft.

Developed in collaboration with industry and international partners, Gateway is a cornerstone of NASA’s Artemis campaign to advance science and exploration on and around the Moon in preparation for the next giant leap: the first human missions to Mars.

Microsoft today issued security updates to fix at least 56 vulnerabilities in its Windows operating systems and supported software, including two zero-day flaws that are being actively exploited.

All supported Windows operating systems will receive an update this month for a buffer overflow vulnerability that carries the catchy name CVE-2025-21418. This patch should be a priority for enterprises, as Microsoft says it is being exploited, has low attack complexity, and no requirements for user interaction.

Tenable senior staff research engineer Satnam Narang noted that since 2022, there have been nine elevation of privilege vulnerabilities in this same Windows component — three each year — including one in 2024 that was exploited in the wild as a zero day (CVE-2024-38193).

“CVE-2024-38193 was exploited by the North Korean APT group known as Lazarus Group to implant a new version of the FudModule rootkit in order to maintain persistence and stealth on compromised systems,” Narang said. “At this time, it is unclear if CVE-2025-21418 was also exploited by Lazarus Group.”

The other zero-day, CVE-2025-21391, is an elevation of privilege vulnerability in Windows Storage that could be used to delete files on a targeted system. Microsoft’s advisory on this bug references something called “CWE-59: Improper Link Resolution Before File Access,” says no user interaction is required, and that the attack complexity is low.

Adam Barnett, lead software engineer at Rapid7, said although the advisory provides scant detail, and even offers some vague reassurance that ‘an attacker would only be able to delete targeted files on a system,’ it would be a mistake to assume that the impact of deleting arbitrary files would be limited to data loss or denial of service.

“As long ago as 2022, ZDI researchers set out how a motivated attacker could parlay arbitrary file deletion into full SYSTEM access using techniques which also involve creative misuse of symbolic links,”Barnett wrote.

One vulnerability patched today that was publicly disclosed earlier is CVE-2025-21377, another weakness that could allow an attacker to elevate their privileges on a vulnerable Windows system. Specifically, this is yet another Windows flaw that can be used to steal NTLMv2 hashes — essentially allowing an attacker to authenticate as the targeted user without having to log in.

According to Microsoft, minimal user interaction with a malicious file is needed to exploit CVE-2025-21377, including selecting, inspecting or “performing an action other than opening or executing the file.”

“This trademark linguistic ducking and weaving may be Microsoft’s way of saying ‘if we told you any more, we’d give the game away,'” Barnett said. “Accordingly, Microsoft assesses exploitation as more likely.”

The SANS Internet Storm Center has a handy list of all the Microsoft patches released today, indexed by severity. Windows enterprise administrators would do well to keep an eye on askwoody.com, which often has the scoop on any patches causing problems.

It’s getting harder to buy Windows software that isn’t also bundled with Microsoft’s flagship Copilot artificial intelligence (AI) feature. Last month Microsoft started bundling Copilot with Microsoft Office 365, which Redmond has since rebranded as “Microsoft 365 Copilot.” Ostensibly to offset the costs of its substantial AI investments, Microsoft also jacked up prices from 22 percent to 30 percent for upcoming license renewals and new subscribers.

Office-watch.com writes that existing Office 365 users who are paying an annual cloud license do have the option of “Microsoft 365 Classic,” an AI-free subscription at a lower price, but that many customers are not offered the option until they attempt to cancel their existing Office subscription.

In other security patch news, Apple has shipped iOS 18.3.1, which fixes a zero day vulnerability (CVE-2025-24200) that is showing up in attacks.

Adobe has issued security updates that fix a total of 45 vulnerabilities across InDesign, Commerce, Substance 3D Stager, InCopy, Illustrator, Substance 3D Designer and Photoshop Elements.

Chris Goettl at Ivanti notes that Google Chrome is shipping an update today which will trigger updates for Chromium based browsers including Microsoft Edge, so be on the lookout for Chrome and Edge updates as we proceed through the week.

A bouquet of thousands of stars in bloom has arrived. This composite image contains the deepest X-ray image ever made of the spectacular star forming region called 30 Doradus.

By combining X-ray data from NASA’s Chandra X-ray Observatory (blue and green) with optical data from NASA’s Hubble Space Telescope (yellow) and radio data from the Atacama Large Millimeter/submillimeter Array (orange), this stellar arrangement comes alive.

Otherwise known as the Tarantula Nebula, 30 Dor is located about 160,000 light-years away in a small neighboring galaxy to the Milky Way known as the Large Magellanic Cloud (LMC). Because it one of the brightest and populated star-forming regions to Earth, 30 Dor is a frequent target for scientists trying to learn more about how stars are born.

With enough fuel to have powered the manufacturing of stars for at least 25 million years, 30 Dor is the most powerful stellar nursery in the local group of galaxies that includes the Milky Way, the LMC, and the Andromeda galaxy.

The massive young stars in 30 Dor send cosmically strong winds out into space. Along with the matter and energy ejected by stars that have previously exploded, these winds have carved out an eye-catching display of arcs, pillars, and bubbles.

A dense cluster in the center of 30 Dor contains the most massive stars astronomers have ever found, each only about one to two million years old. (Our Sun is over a thousand times older with an age of about 5 billion years.)

This new image includes the data from a large Chandra program that involved about 23 days of observing time, greatly exceeding the 1.3 days of observing that Chandra previously conducted on 30 Dor. The 3,615 X-ray sources detected by Chandra include a mixture of massive stars, double-star systems, bright stars that are still in the process of forming, and much smaller clusters of young stars.

There is a large quantity of diffuse, hot gas seen in X-rays, arising from different sources including the winds of massive stars and from the gas expelled by supernova explosions. This data set will be the best available for the foreseeable future for studying diffuse X-ray emission in star-forming regions.

The long observing time devoted to this cluster allows astronomers the ability to search for changes in the 30 Dor’s massive stars. Several of these stars are members of double star systems and their movements can be traced by the changes in X-ray brightness.

A paper describing these results appears in the July 2024 issue of The Astrophysical Journal Supplement Series. NASA’s Marshall Space Flight Center 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 Description

This release features a highly detailed composite image of a star-forming region of space known as 30 Doradus, shaped like a bouquet, or a maple leaf.

30 Doradus is a powerful stellar nursery. In 23 days of observation, the Chandra X-ray telescope revealed thousands of distinct star systems. Chandra data also revealed a diffuse X-ray glow from winds blowing off giant stars, and X-ray gas expelled by exploding stars, or supernovas.

In this image, the X-ray wind and gas takes the shape of a massive purple and pink bouquet with an extended central flower, or perhaps a leaf from a maple tree. The hazy, mottled shape occupies much of the image, positioned just to our left of center, tilted slightly to our left. Inside the purple and pink gas and wind cloud are red and orange veins, and pockets of bright white light. The pockets of white light represent clusters of young stars. One cluster at the heart of 30 Doradus houses the most massive stars astronomers have ever found.

The hazy purple and pink bouquet is surrounded by glowing dots of green, white, orange, and red. A second mottled purple cloud shape, which resembles a ring of smoke, sits in our lower righthand corner.

NASA’s Nancy Grace Roman Space Telescope team has successfully integrated the mission’s deployable aperture cover — a visor-like sunshade that will help prevent unwanted light from entering the telescope — to the outer barrel assembly, another structure designed to shield the telescope from stray light in addition to keeping it at a stable temperature.

“It’s been incredible to see these major components go from computer models to building and now integrating them,” said Sheri Thorn, an aerospace engineer working on Roman’s sunshade at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Since it’s all coming together at Goddard, we get a front row seat to the process. We’ve seen it mature, kind of like watching a child grow up, and it’s a really gratifying experience.”

The sunshade functions like a heavy-duty version of blackout curtains you might use to keep your room extra dark. It will make Roman more sensitive to faint light from across the universe, helping astronomers see dimmer and farther objects. Made of two layers of reinforced thermal blankets, the sunshade is designed to remain folded during launch and deploy after Roman is in space. Three booms will spring upward when triggered electronically, raising the sunshade like a page in a pop-up book.

The sunshade blanket has an inner and outer layer separated by about an inch, much like a double-paned window. “We’re prepared for micrometeoroid impacts that could occur in space, so the blanket is heavily fortified,” said Brian Simpson, Roman’s deployable aperture cover lead at NASA Goddard. “One layer is even reinforced with Kevlar, the same thing that lines bulletproof vests. By placing some space in between the layers we reduce the risk that light would leak in, because it’s unlikely that the light would pass through both layers at the exact same points where the holes were.”
 
Over the course of a few hours, technicians meticulously joined the sunshade to the outer barrel assembly — both Goddard-designed components — in the largest clean room at NASA Goddard. The outer barrel assembly will help keep the telescope at a stable temperature and, like the sunshade, help shield the telescope from stray light and micrometeoroid impacts. It’s fitted with heaters to help ensure the telescope’s mirrors won’t experience wide temperature swings, which make materials expand and contract.
 
“Roman is made up of a lot of separate components that come together after years of design and fabrication,” said Laurence Madison, a mechanical engineer at NASA Goddard. “The deployable aperture cover and outer barrel assembly were built at the same time, and up until the integration the two teams mainly used reference drawings to make sure everything would fit together as they should. So the successful integration was both a proud moment and a relief!”

Both the sunshade and outer barrel assembly have been extensively tested individually, but now that they’re connected engineers are assessing them again. Following the integration, the team tested the sunshade deployment.
 
“Since the sunshade was designed to deploy in space, the system isn’t actually strong enough to deploy itself in Earth’s gravity,” said Matthew Neuman, a mechanical engineer working on Roman’s sunshade at NASA Goddard. “So we used a gravity negation system to offset its weight and verified that everything works as expected.”
 
Next, the components will undergo thermal vacuum testing together to ensure they will function as planned in the temperature and pressure environment of space. Then they’ll move to a shake test to assess their performance during the extreme vibrations they’ll experience during launch.
 
Technicians will join Roman’s solar panels to the outer barrel assembly and sunshade this spring, and then integrate them with the rest of the observatory by the end of the year. 
 
The mission has now passed a milestone called Key Decision Point-D, marking the official transition from the fabrication stage that culminated in the delivery of major components to the phase involving assembly, integration, testing, and launch. The Roman observatory remains on track for completion by fall 2026 and launch no later than May 2027.

Glenn Employees Earn Presidential Early Career Awards for Scientists and Engineers

Two NASA Glenn Research Center employees were among 19 agency researchers recognized as recipients of the Presidential Early Career Award for Scientists and Engineers (PECASE). 

Lyndsey McMillon-Brown was recognized for leadership in photovoltaic research, development, and demonstrations. She was the principal investigator for a Science Technology Mission Directorate-funded Early Career Initiative where she led the development of perovskite photovoltaics, which can be manufactured in space. The team achieved sun-to-electricity power conversion efficiencies of 18%. They tested the durability of the solar cells by flying them in low Earth orbit for 10 months on the Materials International Space Station Experiment platform.   

Timothy M. Smith was recognized for achievements in materials science research, specifically in high-temperature alloy innovation. Building upon his dissertation work, he designed a new high-temperature superalloy with radically improved high-temperature durability. Additionally, he helped develop a new manufacturing process that could produce new metal alloys strengthened by nano oxide particles. This led to the development of a revolutionary high- temperature alloy (GRX-810) designed specifically for additive manufacturing.  

The PECASE Award is the highest honor given by the U.S. government to scientists and engineers who are beginning their research careers.  

NASA Glenn Employee Named AIAA Fellow

Brett A. Bednarcyk, a materials research engineer at NASA’s Glenn Research Center in Cleveland, has been named an American Institute of Aeronautics and Astronautics (AIAA) Fellow. His work is focused on multiscale modeling and integrated computational materials engineering of composite materials and structures. He has co-authored two textbooks on these subjects. 

AIAA Fellows are recognized for their notable and valuable contributions to the arts, sciences, or technology of aeronautics and astronautics.  

Glenn’s Dr. Heather Oravec Named Outstanding Civil Engineer  

The American Society of Civil Engineers (ASCE) Cleveland Chapter has named Dr. Heather Oravec, a mechanical engineering research associate professor supporting NASA Glenn Research Center’s Engineering and Research Support (GEARS) contract team, the 2024 Outstanding Civil Engineer of the Year. Oravec is a research leader in the areas of terramechanics and off-road tire development for planetary rovers and works in NASA Glenn’s Simulated Lunar Operations (SLOPE) Lab. 

This award honors a civil engineer who has made significant contributions to the field and to the community, furthering the recognition of civil engineers through work and influence. 

An experiment studying how solid materials catch fire and burn in the Moon’s gravity was launched on Blue Origin’s New Shepard suborbital flight this month. 

Developed by NASA’s Glenn Research Center in Cleveland together with Voyager Technologies, the Lunar-g Combustion Investigation (LUCI) will help researchers determine if conditions on the Moon – with reduced gravity – might be a more hazardous environment for fire safety. 

On this flight, LUCI tested flammability of cotton-fiberglass fabric and plastic rods, and once launched, the payload capsule rotated at a speed to simulate lunar gravity. NASA Glenn researchers will analyze data post-flight.

LUCI’s findings will help NASA and its partners design safe spacecraft and spacesuits for future Moon and Mars missions.

NASA observed its annual Day of Remembrance on Jan. 23, honoring the members of the NASA family who lost their lives in the pursuit of exploration and discovery for the benefit of humanity. The annual event acknowledges the crews of Apollo 1 and the space shuttles Challenger and Columbia. 

NASA Acting Administrator Janet Petro and astronaut Kayla Barron participated in an observance at Arlington National Cemetery in Arlington, Virginia. Wreaths were laid in memory of the men and women who lost their lives in the quest for space exploration. 

Several agency centers also held observances for NASA Day of Remembrance. NASA’s Glenn Research Center in Cleveland hosted an observance on Jan. 28 with remarks from Center Director Dr. Jimmy Kenyon and a keynote address from the acting director of NASA’s Kennedy Space Center in Florida, Kelvin Manning.  

Kenyon reflected on the loss of the astronauts and the impact on their families. A large part of honoring their legacy, he said, is committing to a culture of safety awareness and practices. Learning what went wrong is vital to safely moving forward into the future. He then introduced a video recognizing the fallen heroes.  

Manning, who worked with the families of the Apollo I astronauts to learn their stories and honor their legacy through an exhibit at NASA Kennedy, shared insights into the causes of the tragedy. He talked about the lessons learned through the investigation that resulted in increased measures for astronaut safety. 

Kenyon then carried a memorial wreath to the front of the stage. NASA Glenn’s Amanda Shalkhauser played Taps, which was followed by a moment of silence. 

Media are invited to visit NASA’s Kennedy Space Center in Florida, to capture imagery of the agency’s Artemis II Orion spacecraft and twin SLS (Space Launch System) solid rocket boosters for the first crewed Artemis mission around the Moon. The event is targeted for Friday, March 7.

NASA’s X-59 quiet supersonic research aircraft took another successful step toward flight with the conclusion of a series of engine performance tests.

In preparation for the X-59’s planned first flight this year, NASA and Lockheed Martin successfully completed the aircraft’s engine run tests in January. The engine, a modified F414-GE-100 that powers the aircraft’s flight and integrated subsystems, performed to expectations during three increasingly complicated tests that ran from October through January at contractor Lockheed Martin’s Skunk Works facility in Palmdale, California.

“We have successfully progressed through our engine ground tests as we planned,” said Raymond Castner, X-59 propulsion lead at NASA’s Glenn Research Center in Cleveland. “We had no major showstoppers. We were getting smooth and steady airflow as predicted from wind tunnel testing. We didn’t have any structural or excessive vibration issues. And parts of the engine and aircraft that needed cooling were getting it.”

The tests began with seeing how the aircraft’s hydraulics, electrical, and environmental control systems performed when the engine was powered up but idling. The team then performed throttle checks, bringing the aircraft up to full power and firing its afterburner – an engine component that generates additional thrust – to maximum.

A third test, throttle snaps, involved moving the throttle swiftly back and forth to validate that the engine responds instantly. The engine produces as much as 22,000 pounds of thrust to achieve a desired cruising speed of Mach 1.4 (925 miles per hour) at an altitude of approximately 55,000 feet.

The X-59’s engine, similar to those aboard the U.S. Navy’s F-18 Super Hornet, is mounted on top of the aircraft to reduce the level of noise reaching the ground. Many features of the X-59, including its 38-foot-long nose, are designed to lower the noise of a sonic boom to that of a mere “thump,” similar to the sound of a car door slamming nearby.

Next steps before first flight will include evaluating the X-59 for potential electromagnetic interference effects, as well as “aluminum bird” testing, during which data will be fed to the aircraft under both normal and failure conditions. A series of taxi tests and other preparations will also take place before the first flight.

The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to commercial supersonic flight over land by making sonic booms quieter.

You would not expect to see NASA at a car show—but that’s exactly where Johnson Space Center employees were from Jan. 29 to Feb. 2, 2025, driving the future of space exploration forward. 

At the Houston AutoBoative Show, a fusion of the auto and boat show, NASA rolled out its Artemis exhibit at NRG Center for the first time, introducing vehicle enthusiasts to the technologies NASA and commercial partners will use to explore more of the lunar surface than ever before. 

The Artemis exhibit stood alongside some of the world’s most advanced cars and boats, offering visitors an up-close look at lunar terrain vehicle mockups from Astrolab, Intuitive Machines, and Lunar Outpost. Later this year, NASA will select the rover that will fly to the Moon as humanity prepares for the next giant leap. 

In addition to the rovers, the exhibit featured a mockup of JAXA’s (Japan Aerospace Exploration Agency) pressurized rover, designed as a mobile habitat for astronauts, and Axiom Space’s lunar spacesuit, developed for Artemis III astronauts. 

These capabilities will allow astronauts to explore, conduct science research, and live and work on the lunar surface.  

Johnson Director Vanessa Wyche visited the Artemis exhibit to highlight the importance of these technologies in advancing lunar exploration. Every lesson learned on the Moon will help scientists and engineers develop the strategies, technologies, and experience needed to send astronauts to Mars.  

“By bringing the excitement of lunar exploration to the AutoBoative Show, NASA aims to inspire the next generation of explorers to dream bigger, push farther, and help shape humanity’s future in space,” Wyche said.  

NASA’s Artemis campaign is setting the stage for long-term human exploration, working with commercial and international partners to establish a sustained presence on the Moon before progressing to Mars. 

To make this vision a reality, NASA is developing rockets, spacecraft, landing systems, spacesuits, rovers, habitats, and more.  

Some of the key elements on display at the show included:

• The Orion spacecraft – Designed to take astronauts farther into deep space. Orion will launch atop NASA’s Space Launch System (SLS) rocket, carrying the crew to the Moon on Artemis missions and safely returning them to Earth.

• Lunar terrain vehicles – Developed to transport astronauts across the rugged lunar surface or be remotely operated. NASA recently put these rover mockups to the test at Johnson, where astronauts and engineers, wearing spacesuits, ran through critical maneuvers, tasks, and emergency drills—including a simulated crew rescue.

• Next-gen spacesuits and tools – Through Johnson’s Extravehicular Activity and Human Surface Mobility Program, astronauts’ gear and equipment are designed to ensure safety and efficiency while working on the Moon’s surface.

Guests had the chance to step into the role of an astronaut with interactive experiences like: 

• Driving a lunar rover simulator – Testing their skills at the wheel of a virtual Moon rover. 

• Practicing a simulated Orion docking – Experiencing the precision needed to connect to Gateway in lunar orbit. 

• Exploring Artemis II and III mission roadmaps – Learning about NASA’s upcoming missions and goals. 

Attendees also discovered how American companies are delivering science and technology to the Moon through NASA’s Commercial Lunar Payload Services initiative. 

“Everyone can relate to exploration, so it was great to teach people the importance lunar rovers will have on astronauts’ abilities to explore more of the lunar surface while conducting science,” said Victoria Ugalde, communications strategist for the Extravehicular Activity and Human Surface Mobility Program, who coordinated the lunar rovers’ appearance at the show.

NASA has selected SpaceX of Starbase, Texas, to provide the launch service for the agency’s Pandora mission, which will study at least 20 known exoplanets and their host stars to find out how changes in stars affect our observations of exoplanet atmospheres.

The selection is part of NASA’s Venture-Class Acquisition of Dedicated and Rideshare (VADR) launch services contract. This contract allows the agency to make fixed-price indefinite-delivery/indefinite-quantity awards during VADR’s five-year ordering period, with a maximum total value of $300 million across all contracts.

During its one-year primary mission, Pandora will observe each exoplanet 10 times, observing for 24 hours each visit. It will capture critical data about the planet and its host star during transits, an event where a planet crosses in front of the star it orbits.

The satellite will use an innovative 17-inch (45-centimeter)-wide all-aluminum telescope to simultaneously measure the visible and near-infrared brightness of the host star and obtain near-infrared spectra of the transiting planet. This will allow scientists to cleanly separate star and planetary signals, knowledge that will enhance observations from NASA’s James Webb Space Telescope and future missions searching for habitable worlds, like the agency’s Habitable Worlds Observatory.

Pandora is a joint effort between NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Lawrence Livermore National Laboratory in California. The Astrophysics Pioneers program, from the Astrophysics Division at NASA Headquarters in Washington, funds Pandora and other astrophysics science missions using smaller, lower cost hardware and payloads. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contract.

Astronomers may have discovered a scrawny star bolting through the middle of our galaxy with a planet in tow. If confirmed, the pair sets a new record for the fastest-moving exoplanet system, nearly double our solar system’s speed through the Milky Way.

The planetary system is thought to move at least 1.2 million miles per hour, or 540 kilometers per second.

“We think this is a so-called super-Neptune world orbiting a low-mass star at a distance that would lie between the orbits of Venus and Earth if it were in our solar system,” said Sean Terry, a postdoctoral researcher at the University of Maryland, College Park and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Since the star is so feeble, that’s well outside its habitable zone. “If so, it will be the first planet ever found orbiting a hypervelocity star.”

A paper describing the results, led by Terry, was published in The Astronomical Journal on February 10.

A Star on the Move

The pair of objects was first spotted indirectly in 2011 thanks to a chance alignment. A team of scientists combed through archived data from MOA (Microlensing Observations in Astrophysics) – a collaborative project focused on a microlensing survey conducted using the University of Canterbury Mount John Observatory in New Zealand — in search of light signals that betray the presence of exoplanets, or planets outside our solar system.

Microlensing occurs because the presence of mass warps the fabric of space-time. Any time an intervening object appears to drift near a background star, light from the star curves as it travels through the warped space-time around the nearer object. If the alignment is especially close, the warping around the object can act like a natural lens, amplifying the background star’s light.

In this case, microlensing signals revealed a pair of celestial bodies. Scientists determined their relative masses (one is about 2,300 times heavier than the other), but their exact masses depend on how far away they are from Earth. It’s sort of like how the magnification changes if you hold a magnifying glass over a page and move it up and down.

“Determining the mass ratio is easy,” said David Bennett, a senior research scientist at the University of Maryland, College Park and NASA Goddard, who co-authored the new paper and led the original study in 2011. “It’s much more difficult to calculate their actual masses.”

The 2011 discovery team suspected the microlensed objects were either a star about 20 percent as massive as our Sun and a planet roughly 29 times heavier than Earth, or a nearer “rogue” planet about four times Jupiter’s mass with a moon smaller than Earth.

To figure out which explanation is more likely, astronomers searched through data from the Keck Observatory in Hawaii and ESA’s (European Space Agency’s) Gaia satellite. If the pair were a rogue planet and moon, they’d be effectively invisible – dark objects lost in the inky void of space. But scientists might be able to identify the star if the alternative explanation were correct (though the orbiting planet would be much too faint to see).

They found a strong suspect located about 24,000 light-years away, putting it within the Milky Way’s galactic bulge — the central hub where stars are more densely packed. By comparing the star’s location in 2011 and 2021, the team calculated its high speed.

But that’s just its 2D motion; if it’s also moving toward or away from us, it must be moving even faster. Its true speed may even be high enough to exceed the galaxy’s escape velocity of just over 1.3 million miles per hour, or about 600 kilometers per second. If so, the planetary system is destined to traverse intergalactic space many millions of years in the future.

“To be certain the newly identified star is part of the system that caused the 2011 signal, we’d like to look again in another year and see if it moves the right amount and in the right direction to confirm it came from the point where we detected the signal,” Bennett said.

“If high-resolution observations show that the star just stays in the same position, then we can tell for sure that it is not part of the system that caused the signal,” said Aparna Bhattacharya, a research scientist at the University of Maryland, College Park and NASA Goddard who co-authored the new paper. “That would mean the rogue planet and exomoon model is favored.”

NASA’s upcoming Nancy Grace Roman Space Telescope will help us find out how common planets are around such speedy stars, and may offer clues to how these systems are accelerated. The mission will conduct a survey of the galactic bulge, pairing a large view of space with crisp resolution.

“In this case we used MOA for its broad field of view and then followed up with Keck and Gaia for their sharper resolution, but thanks to Roman’s powerful view and planned survey strategy, we won’t need to rely on additional telescopes,” Terry said. “Roman will do it all.”

Measuring water loss from space

This study showed that the International Space Station’s ECOSTRESS instrument estimates of evapotranspiration (transfer of water to the atmosphere from Earth’s surface and plants) are comparable to ground-based reference values. This finding suggests space measurements could provide guidance for improved water management on large scales.

Worsening droughts due to climate change require better water management. Evapotranspiration is a critical part of the hydrologic cycle, but data are lacking on local water conditions and demands. California’s Eastern Municipal Water District uses the ground-based California Irrigation Management Information System to track evapotranspiration, but it has limited spatial coverage and consistency. Space-based estimates could be better and more consistent.

Four-legged robotic retrievers

Space station crew members successfully located and retrieved an object in a simulated Mars environment using a remotely controlled four-legged robot, Bert. Legged robots could provide the ability to explore and survey different extraterrestrial surfaces on future missions.

On uneven lunar and planetary surfaces, robots with legs could explore areas inaccessible to wheeled rovers. Surface Avatar, an investigation from ESA (European Space Agency), evaluated remote control of multiple robots in space, providing information on how human operators respond to physical feedback (such as feeling a bump when a robot arm makes contact) and identifying challenges for orbit-to-ground remote operation of robots. The German Aerospace Center is developing Bert.

Technology supports atmospheric studies

Researchers found that the Compact Thermal Imager (CTI) on the space station produced scientifically useful imagery of atmospheric phenomena, including gravity waves, clouds, and volcanic plumes. This technology could change current practices and instrument design for remote sensing of Earth from space.

The CTI is mounted on hardware for Robotic Refueling Mission 3, which tested technology for the robotic transfer and storage of cryogenic fluids in microgravity. The station’s orbit provides near-global coverage and CTI has reduced size, energy use, and cost. Its images can measure fires, ice sheets, glaciers, and snow surface temperatures on the ground and the transfer of water from soil and plants into the atmosphere.
