NASA, Oxford Discover Warmer Uranus Than Once Thought
KEY POINTS
- Jupiter, Saturn, and Neptune each emit more energy than they receive from the Sun, meaning they have comparatively warm interiors.
- NASA’s Uranus flyby with Voyager 2 in 1986 found the planet colder than expected, which challenged ideas of how planets formed and evolved.
- However, with advanced computer modeling and a new look at old data, scientists think the planet may actually be warmer than previously expected.
For millennia, astronomers thought Uranus was no more than a distant star. It wasn’t until the late 18th century that Uranus was universally accepted as a planet. To this day, the ringed, blue world subverts scientists’ expectations, but new NASA research helps puzzle out some of the world’s mystique.
This zoomed-in image of Uranus, captured by the Near-Infrared Camera on NASA’s James Webb Space Telescope on Feb. 6, 2023, reveals stunning views of Uranus’ rings. Credits: NASA, ESA, CSA, STScIUranus is unlike any other planet in our solar system. It spins on its side, which means each pole directly faces the Sun for a continuous 42-year “summer.” Uranus also rotates in the opposite direction of all planets except Venus. Data from NASA’s Voyager 2 Uranus flyby in 1986 also suggested the planet is unusually cold inside, challenging scientists to reconsider fundamental theories of how planets formed and evolved throughout our solar system.
“Since Voyager 2’s flyby, everybody has said Uranus has no internal heat,” said Amy Simon, a planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “But it’s been really hard to explain why that is, especially when compared with the other giant planets.”
These Uranus projections came from only one up-close measurement of the planet’s emitted heat made by Voyager 2: “Everything hinges on that one data point,” said Simon. “That is part of the problem.”
Now, using an advanced computer modeling technique and revisiting decades of data, Simon and a team of scientists have found that Uranus does in fact generate some heat, as they reported on May 16 in the Monthly Notices of the Royal Astronomical Society journal.
A planet’s internal heat can be calculated by comparing the amount of energy it receives from the Sun to the amount it of energy it releases into space in the form of reflected light and emitted heat. The solar system’s other giant planets — Saturn, Jupiter, and Neptune — emit more heat than they receive, which means the extra heat is coming from inside, much of it left over from the high-energy processes that formed the planets 4.5 billion years ago. The amount of heat a planet exudes could be an indication of its age: the less heat released relative to the heat absorbed from the Sun, the older the planet is.
Uranus stood out from the other planets because it appeared to give off as much heat as it received, implying it had none of its own. This puzzled scientists. Some hypothesized that perhaps the planet is much older than all the others and has cooled off completely. Others proposed that a giant collision — the same one that may have knocked the planet on its side — blasted out all of Uranus’ heat. But none of these hypotheses satisfied scientists, motivating them to solve Uranus’ cold case.
“We thought, ‘Could it really be that there is no internal heat at Uranus?’” said Patrick Irwin, the paper’s lead author and professor of planetary physics at the University of Oxford in England. “We did many calculations to see how much sunshine is reflected by Uranus and we realized that it is actually more reflective than people had estimated.”
The researchers set out to determine Uranus’ full energy budget: how much energy it receives from the Sun compared to how much it reflects as sunlight and how much it emits as heat. To do this, they needed to estimate the total amount of light reflected from the planet at all angles. “You need to see the light that’s scattered off to the sides, not just coming straight back at you,” Simon said.
To get the most accurate estimate of Uranus’ energy budget yet, Oxford researchers developed a computer model that brought together everything known about Uranus’ atmosphere from decades of observations from ground- and space-based telescopes, including NASA’s Hubble Space Telescope and NASA’s Infrared Telescope Facility in Hawaii. The model included information about the planet’s hazes, clouds, and seasonal changes, all of which affect how sunlight is reflected and how heat escapes.
These side-by-side images of Uranus, taken eight years apart by NASA’s Hubble Space Telescope, show seasonal changes in the planet’s reflectivity. The left image shows the planet seven years after its northern spring equinox when the Sun was shining just above its equator. The second photo, taken six years before the planet’s summer solstice, portrays a bright and large northern polar cap. Credit: NASA, ESA, STScI, A. Simon (NASA-GSFC), M. H. Wong (UC Berkeley), J. DePasquale (STScI)The researchers found that Uranus releases about 15% more energy than it receives from the Sun, a figure that is similar to another recent estimate from a separate study funded in part by NASA that was published July 14 in Geophysical Research Letters. These studies suggest Uranus it has its own heat, though still far less than its neighbor Neptune, which emits more than twice the energy it receives.
“Now we have to understand what that remnant amount of heat at Uranus means, as well as get better measurements of it,” Simon said.
Unraveling Uranus’ past is useful not only for mapping the timeline of when solar system planets formed and migrated to their current orbits, but it also helps scientists better understand many of the planets discovered outside the solar system, called exoplanets, a majority of which are the same size as Uranus.

NASA’s X-59 Quiet Supersonic Aircraft Begins Taxi Tests
2 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater)NASA/Jacob Shaw
NASA’s X-59 quiet supersonic research aircraft has officially begun taxi tests, marking the first time this one-of-a-kind experimental aircraft has moved under its own power.
NASA test pilot Nils Larson and the X-59 team, made up of NASA and contractor Lockheed Martin personnel, completed the aircraft’s first low-speed taxi test at U.S. Air Force Plant 42 in Palmdale, California, on July 10, 2025.
The taxiing represents the X-59’s last series of ground tests before first flight. Over the coming weeks, the aircraft will gradually increase its speed, leading up to a high-speed taxi test that will take the aircraft just short of the point where it would take off.
During the low-speed tests, engineers and flight crews monitored how the X-59 handled as it moved across the runway, working to validate critical systems like steering and braking. These checks help ensure the aircraft’s stability and control across a range of conditions, giving pilots and engineers confidence that all systems are functioning as expected.
The X-59 is the centerpiece of NASA’s Quesst mission, which aims to demonstrate quiet supersonic flight by reducing the loud sonic boom to a quieter “thump.” Data gathered from the X-59 will be shared with U.S. and international regulators to inform the establishment of new, data-driven acceptable noise thresholds related to supersonic commercial flight over land.

NASA to Launch SNIFS, Sun’s Next Trailblazing Spectator
4 min read
NASA to Launch SNIFS, Sun’s Next Trailblazing SpectatorJuly will see the launch of the groundbreaking Solar EruptioN Integral Field Spectrograph mission, or SNIFS. Delivered to space via a Black Brant IX sounding rocket, SNIFS will explore the energy and dynamics of the chromosphere, one of the most complex regions of the Sun’s atmosphere. The SNIFS mission’s launch window at the White Sands Missile Range in New Mexico opens on Friday, July 18.
The chromosphere is located between the Sun’s visible surface, or photosphere, and its outer layer, the corona. The different layers of the Sun’s atmosphere have been researched at length, but many questions persist about the chromosphere. “There’s still a lot of unknowns,” said Phillip Chamberlin, a research scientist at the University of Colorado Boulder and principal investigator for the SNIFS mission.

These solar eruptions are the main drivers of space weather, the hazardous conditions in near-Earth space that threaten satellites and endanger astronauts. The SNIFS mission aims to learn more about how energy is converted and moves through the chromosphere, where it can ultimately power these massive explosions.
“To make sure the Earth is safe from space weather, we really would like to be able to model things,” said Vicki Herde, a doctoral graduate of CU Boulder who worked with Chamberlin to develop SNIFS.

This video, captured on Feb. 22, 2024, shows a solar flare — as seen in the bright flash on the upper left.Credit: NASA/SDOThe SNIFS mission is the first ever solar ultraviolet integral field spectrograph, an advanced technology combining an imager and a spectrograph. Imagers capture photos and videos, which are good for seeing the combined light from a large field of view all at once. Spectrographs dissect light into its various wavelengths, revealing which elements are present in the light source, their temperature, and how they’re moving — but only from a single location at a time.
The SNIFS mission combines these two technologies into one instrument.
“It’s the best of both worlds,” said Chamberlin. “You’re pushing the limit of what technology allows us to do.”
By focusing on specific wavelengths, known as spectral lines, the SNIFS mission will help scientists to learn about the chromosphere. These wavelengths include a spectral line of hydrogen that is the brightest line in the Sun’s ultraviolet (UV) spectrum, and two spectral lines from the elements silicon and oxygen. Together, data from these spectral lines will help reveal how the chromosphere connects with upper atmosphere by tracing how solar material and energy move through it.
The SNIFS mission will be carried into space by a sounding rocket. These rockets are effective tools for launching and carrying space experiments and offer a valuable opportunity for hands-on experience, particularly for students and early-career researchers.

Chamberlin emphasized how beneficial these types of missions can be for science and engineering students like Herde, or the next generation of space scientists, who “come with a lot of enthusiasm, a lot of new ideas, new techniques,” he said.
The entirety of the SNIFS mission will likely last up to 15 minutes. After launch, the sounding rocket is expected to take 90 seconds to make it to space and point toward the Sun, seven to eight minutes to perform the experiment on the chromosphere, and three to five minutes to return to Earth’s surface.

The rocket will drift around 70 to 80 miles (112 to 128 kilometers) from the launchpad before its return, so mission contributors must ensure it will have a safe place to land. White Sands, a largely empty desert, is ideal.
Herde, who spent four years working on the rocket, expressed her immense excitement for the launch. “This has been my baby.”

NASA Program Builds Bridge From Military to Civilian Careers for Johnson Team Members
Of all the possible entry points to NASA, the agency’s SkillBridge Program has been instrumental in helping servicemembers transition from the military and into civilian careers. Offered in partnership with the Department of Defense (DoD), the program enables individuals to spend their final months of military service working with a NASA office or organization. SkillBridge fellows work anywhere from 90 to 180 days, contributing their unique skillsets to the agency while building their network and knowledge.
The Johnson Space Center in Houston hosted NASA’s first SkillBridge fellow in 2019, paving the way for dozens of others to follow. SkillBridge participants are not guaranteed a job offer at the end of their fellowship, but many have gone on to accept full-time positions with NASA. About 25 of those former fellows currently work at Johnson, filling roles as varied as their military experiences.

He ended his 30 years of service as the administration, academics, and operations chief for the Marine Corps University in Quantico, Virginia, where he was also an adjunct professor. Shears completed a SkillBridge fellowship with FOD in the summer and fall of 2023, supporting the instructional systems design team. He was hired as a full-time employee upon his military retirement and currently serves as an instructional systems designer for the Instructor Training Module, Mentorship Module, and Spaceflight Academy. He conducts training needs analysis for FOD, as well.

He spent the last three of his nearly 24-year Air Force career serving as the deputy director of the DoD Human Spaceflight Payloads Office at Johnson. His team oversaw the development, integration, launch, and operation of payloads hosting DoD experiments on small satellites and the International Space Station. He also became a certified capsule communicator, or capcom, in December 2022, and was the lead capcom for SpaceX’s 28th commercial resupply services mission to the orbiting laboratory.
Zavala’s SkillBridge fellowship was in Johnson’s Astronaut Office, where he worked as a capcom, capcom instructor, and an integration engineer supporting the Extravehicular Activity and Human Surface Mobility Program. He was involved in developing a training needs analysis and agency simulators for the human landing system, among other projects.
He officially joined the center team as a full-time contractor in August 2024. He is currently a flight operations safety officer within the Flight Operations Directorate (FOD) and continues to serve as a part-time capcom.

Images courtesy of Carl JohnsonCarl Johnson thanks his wife for helping him find a path to NASA. While she was a Pathways intern — and his girlfriend at the time — she gave him a tour of the center that inspired him to join the agency when he was ready to leave the Army. She helped connect him to one of the center’s SkillBridge coordinators and the rest is history.
Johnson was selected for a SkillBridge fellowship in the Dynamic System Test Branch. From February to June 2023, he supported development of the lunar terrain vehicle ground test unit and contributed to the Active Response Gravity Offload System (ARGOS), which simulates reduced gravity for astronaut training.
Johnson officially joined the center team as an electrical engineer in the Engineering Directorate’s Software, Robotics, and Simulation Division in September 2023. He is currently developing a new ARGOS spacewalk simulator and training as an operator and test director for another ARGOS system.
Johnson holds an electrical engineering degree from the United States Military Academy. He was on active duty in the Army for 10 years and concluded his military career as an instructor and small group leader for the Engineer Captains Career Course. In that role, he was responsible for instructing, mentoring, and preparing the next generation of engineer captains.

His last role was maintenance senior chief with Air Test and Evaluation Squadron 31, known as “the Dust Devils.” Quinn managed the operations and maintenance of 33 aircraft, ensuring their readiness for complex missions and contributing to developmental flight tests and search and rescue missions. He applied that experience to his SkillBridge fellowship in quality assurance at Ellington Field in 2024. Quinn worked to enhance flight safety and astronaut training across various aircraft, including the T-38, WB-57, and the Super Guppy. He has continued contributing to those projects since being hired as a full-time quality assurance employee in 2025.

His last role in the military was as a director of staff at the Air Command and Staff College at Maxwell Air Force Base in Montgomery, Alabama. There he served as a graduate-level instructor teaching international security concepts to mid-level officers and civilian counterparts from all branches of the military and various federal agencies.
Ulat started his SkillBridge fellowship as an integration engineer in Johnson’s X-Lab, supporting avionics, power, and software integration for the Gateway lunar space station. Ulat transitioned directly from his fellowship into a similar full-time position at Johnson in May 2024.
Ariel Vargas receives a commendation during his Army service (left) and in his official NASA portrait.Ariel Vargas transitioned to NASA after serving for five years in the Army. His last role in the military was as a signal officer, which involved leading teams managing secure communications and network operations in dynamic and mission-critical environments in the Middle East and the United States.
Vargas completed his SkillBridge fellowship in November 2023, supporting Johnson’s Office of the Chief Information Officer (OCIO). During his fellowship, he led a center-wide wireless augmentation project that modernized Johnson’s connectivity.
He became a full-time civil servant in May 2024 and currently serves as the business operations and partnerships lead within OCIO, supporting a digital transformation initiative. In this role, he leads efforts to streamline internal business operations, manage strategic partnerships, and drive cross-functional collaboration.
“My time in the military taught me the value of service, leadership, and adaptability—qualities that I now apply daily in support of NASA’s mission,” Vargas said. “I’m proud to be part of the Johnson team and hope my story can inspire other service members considering the SkillBridge pathway.”

Summer Triangle Corner: Vega
3 min read
Summer Triangle Corner: VegaIf you live in the Northern Hemisphere and look up during July evenings, you’ll see the brilliant star Vega shining overhead. Did you know that Vega is one of the most studied stars in our skies? As one of the brightest summer stars, Vega has fascinated astronomers for thousands of years.
Vega is the brightest star in the small Greek constellation of Lyra, the harp. It’s also one of the three points of the large “Summer Triangle” asterism, making Vega one of the easiest stars to find for novice stargazers. Ancient humans from 14,000 years ago likely knew Vega for another reason: it was the Earth’s northern pole star! Compare Vega’s current position with that of the current north star, Polaris, and you can see how much the direction of Earth’s axis changes over thousands of years. This slow movement of axial rotation is called precession, and in 12,000 years, Vega will return to the northern pole star position.
Bright Vega has been observed closely since the beginning of modern astronomy and even helped to set the standard for the current magnitude scale used to categorize the brightness of stars. Polaris and Vega have something else in common, besides being once and future pole stars: their brightness varies over time, making them variable stars. Variable stars’ light can change for many different reasons. Dust, smaller stars, or even planets may block the light we see from the star. Or the star itself might be unstable with active sunspots, expansions, or eruptions changing its brightness. Most stars are so far away that we only record the change in light, and can’t see their surface.
Astronomers have discovered what appears to be a large asteroid belt around the bright star Vega, as illustrated here at left in brown. The ring of warm, rocky debris was detected using NASA’s Spitzer Space Telescope, and the European Space Agency’s Herschel Space Observatory, in which NASA plays an important role.NASA/JPL-CaltechNASA’s TESS satellite has ultra-sensitive light sensors primed to look for the tiny dimming of starlight caused by transits of extrasolar planets. Their sensitivity also allowed TESS to observe much smaller pulsations in a certain type of variable star’s light than previously observed. These observations of Delta Scuti variable stars will help astronomers model their complex interiors and make sense of their distinct, seemingly chaotic pulsations. This is a major contribution towards the field of astroseismology: the study of stellar interiors via observations of how sound waves “sing” as they travel through stars. The findings may help settle the debate over what kind of variable star Vega is. Find more details on this research, including a sonification demo that lets you “hear” the heartbeat of one of these stars, at: bit.ly/DeltaScutiTESS
In 2024, the James Webb Space Telescope revisited the Vega system to reveal a 100-billion-mile-wide disk of dust around this star. While the debris disk is confirmed, there is no evidence of planets as of today.

NASA to Preview Advanced US-India Radar Mission Ahead of Launch
NASA will host a news conference at 12 p.m. EDT Monday, July 21, to discuss the upcoming NISAR (NASA-ISRO Synthetic Aperture Radar) mission.
The Earth-observing satellite, a first-of-its-kind collaboration between NASA and ISRO (Indian Space Research Organisation), carries an advanced radar system that will help protect communities by providing a dynamic, three-dimensional view of Earth in unprecedented detail and detecting the movement of land and ice surfaces down to the centimeter.
The NISAR mission will lift off from ISRO’s Satish Dhawan Space Centre in Sriharikota, on India’s southeastern coast. Launch is targeted for no earlier than late July.
NASA’s Jet Propulsion Laboratory in Southern California will stream the briefing live on its X, Facebook, and YouTube channels. Learn how to watch NASA content through a variety of platforms, including social media.
Participants in the news conference include:
- Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters
- Karen St. Germain, director, Earth Science Division, NASA Headquarters
- Wendy Edelstein, deputy project manager, NISAR, NASA JPL
- Paul Rosen, project scientist, NISAR, NASA JPL
To ask questions by phone, members of the media must RSVP no later than two hours before the start of the event to: rexana.v.vizza@jpl.nasa.gov. NASA’s media accreditation policy is available online. Questions can be asked on social media during the briefing using #AskNISAR.
With its two radar instruments — an S-band system provided by ISRO and an L-band system provided by NASA — NISAR will use a technique known as synthetic aperture radar (SAR) to scan nearly all the planet’s land and ice surfaces twice every 12 days. Each system’s signal is sensitive to different sizes of features on Earth’s surface, and each specializes in measuring different attributes, such as moisture content, surface roughness, and motion.
These capabilities will help scientists better understand processes involved in natural hazards and catastrophic events, such as earthquakes, volcanic eruptions, land subsidence, and landslides.
Additionally, NISAR’s cloud penetrating ability will aid urgent responses to communities during weather disasters such as hurricanes, storm surge, and flooding. The detailed maps the mission creates also will provide information on both gradual and sudden changes occurring on Earth’s land and ice surfaces.
Managed by Caltech for NASA, JPL leads the U.S. component of the NISAR project and provided the L-band SAR. NASA JPL also provided the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the Near Space Network, which will receive NISAR’s L-band data.
Multiple ISRO centers have contributed to NISAR. The Space Applications Centre is providing the mission’s S-band SAR. The U R Rao Satellite Centre provided the spacecraft bus. The rocket is from Vikram Sarabhai Space Centre, launch services are through Satish Dhawan Space Centre, and satellite mission operations are by the ISRO Telemetry Tracking and Command Network. The National Remote Sensing Centre is responsible for S-band data reception, operational products generation, and dissemination.

NASA’s Chandra Finds Baby Exoplanet is Shrinking
A baby planet is shrinking from the size of Jupiter with a thick atmosphere to a small, barren world, according to a new study from NASA’s Chandra X-ray Observatory.
This transformation is happening as the host star unleashes a barrage of X-rays that is tearing the young planet’s atmosphere away at an enormous rate.
The planet, named TOI 1227 b, is in an orbit around a red dwarf star about 330 light-years from Earth. TOI 1227 b orbits very close to its star — less than a fifth the distance that Mercury orbits the Sun. The new study shows this planet outside our solar system, or exoplanet, is a “baby” at a mere 8 million years old. By comparison, the Earth is about 5 billion years old, or nearly a thousand times older. That makes it the second youngest planet ever to be observed passing in front of its host star (also called a transit). Previously the planet had been estimated by others to be about 11 million years old.
A research team found that X-rays from its star are blasting TOI 1227 b and tearing away its atmosphere at such a rate that the planet will entirely lose it in about a billion years. At that point the planet will have lost a total mass equal to about two Earth masses, down from about 17 times the mass of Earth now.
“It’s almost unfathomable to imagine what is happening to this planet,” said Attila Varga, a Ph.D. student at the Rochester Institute of Technology (RIT) in New York, who led the study. “The planet’s atmosphere simply cannot withstand the high X-ray dose it’s receiving from its star.”
It is probably impossible for life to exist on TOI 1227 b, either now or in the future. The planet is too close to its star to fit into any definition of a ‘habitable zone,’ a term astronomers use to determine if planets around other stars could sustain liquid water on their surface.
The star that hosts TOI 1227 b, which is called TOI 1227, is only about a tenth the mass of the Sun and is much cooler and fainter in optical light. In X-rays, however, TOI 1227 is brighter than the Sun and is subjecting this planet, in its very close orbit, to a withering assault. The mass of TOI 1227 b, while not well understood, is likely similar to that of Neptune, but its diameter is three times larger than Neptune’s (making it similar in size to Jupiter).
“A crucial part of understanding planets outside our solar system is to account for high-energy radiation like X-rays that they’re receiving,” said co-author Joel Kastner, also of RIT. “We think this planet is puffed up, or inflated, in large part as a result of the ongoing assault of X-rays from the star.”
The team used new Chandra data to measure the amount of X-rays from the star that are striking the planet. Using computer models of the effects of these X-rays, they concluded the X-rays will have a transformative effect, rapidly stripping away the planet’s atmosphere. They estimate that the planet is losing a mass equivalent to a full Earth’s atmosphere about every 200 years.
“The future for this baby planet doesn’t look great,” said co-author Alexander Binks of the Eberhard Karls University of Tübingen in Germany. “From here, TOI 1227 b may shrink to about a tenth of its current size and will lose more than 10 percent of its weight.”
The researchers used different sets of data to estimate the age of TOI 1227 b. One method exploits measurements of how TOI 1227 b’s host star moves through space compared to nearby populations of stars with known ages. A second method compared the brightness and surface temperature of the star with theoretical models of evolving stars.
Of all the exoplanets astronomers have found with ages less than 50 million years, TOI 1227 b stands out for having the longest year and the host planet with the lowest mass.
A paper describing these results has been accepted publication in The Astrophysical Journal, and a preprint is available here.

Visual DescriptionThis release features an artist’s illustration of a Jupiter-sized planet closely orbiting a faint red star. An inset image, showing the star in X-ray light from Chandra, is superimposed on top of the illustration at our upper left corner.
At our upper right, the red star is illustrated as a ball made of intense fire. The planet, slightly smaller than the star, is shown at our lower left. Powerful X-rays from the star are tearing away the atmosphere of the planet, causing wisps of material to flow away from the planet’s surface in the opposite direction from the star. This gives the planet a slight resemblance to a comet, complete with a tail.
X-ray data from Chandra, presented in the inset image, shows the star as a small purple orb on a black background. Astronomers used the Chandra data to measure the amount of X-rays striking the planet from the star. They estimate that the planet is losing a mass equivalent to a full Earth’s atmosphere about every 200 years, causing it to ultimately shrink from the size of Jupiter down to a small, barren world.

Article 2 days agoNASA Software Catalog Puts Agency Solutions at Innovators’ Fingertips
NASA’s latest open Software Catalog, released Wednesday, offers more than 1,200 downloadable codes developed by agency engineers that could enable faster solutions to energize the space economy and stimulate American ingenuity. The catalog is part of NASA’s effort to place advanced technologies, including agency software, into the hands of businesses, researchers, and entrepreneurs to foster economic growth and innovation.
Agency developers will provide more information about the Software Catalog, the only repository of its kind in the federal government, during NASA’s summer software webinar series beginning Tuesday, July 22.
“NASA has droves of talented experts creating software to automate elements of agency missions,” said Dan Lockney, program executive, Technology Transfer at NASA Headquarters in Washington. “The resulting efficiency benefits humankind, and its public value increases exponentially when the agency provides access to those software programs for companies, enabling them to save time and money, improve commercial offerings, and build their businesses.”
The four webinars accompanying this year’s NASA Software Catalog feature developers of popular programs for mission planning, systems design, propulsion analysis, and more, each consisting of a presentation followed by a live question-and-answer session.
Programs offered in NASA’s 2025-2026 Software Catalog are grouped into 15 categories that may be useful for organizations working with spacecraft and aircraft. For example, the Vehicle Management category includes a tool for designing satellite constellations and a software library for minimizing public safety risks around expendable launch vehicles. The Aeronautics section includes several programs that are widely used by industry for creating, modifying, and analyzing aircraft designs.
Although the categories have specific themes, the codes are meant to be useful to various innovators. Companies can use aircraft programs NASA wrote to design cars, trucks, and countless other products. The catalog’s Business Systems and Project Management section includes software for estimating project costs, building and assessing complex schedules, and uncovering root causes of mishaps. Other popular programs support 3D rendering for simulation and virtual reality, bring hyper-accuracy to GPS tracking, and analyze electrical power system architectures.
NASA released its first Software Catalog more than a decade ago in 2013, and since then, the agency’s annual rate of software downloads has skyrocketed, reaching up to 5,722 downloads in a single year.
The Software Catalog is a product of NASA’s Technology Transfer program, managed by the agency’s Space Technology Mission Directorate. NASA routinely makes improvements to the Software Catalog website, ensuring the process is fast and easy. Access restrictions apply to some software that may be limited to use by U.S. citizens or for U.S. government purposes only.

NASA Sees Key Progress on Starlab Commercial Space Station
As NASA continues its transition toward a commercial low Earth orbit marketplace, an agency-supported commercial space station, Starlab, recently completed five development and design milestones. Starlab’s planned design consists of a service module and a habitat that will be launched to orbit on a single flight.
The milestones, part of a NASA Space Act Agreement awarded in 2021, focused on reviews of Starlab’s preliminary design and safety, as well as spacecraft mockup and procurement plans. Each milestone provides NASA insight into the company’s development progress.
“As we work toward the future of low Earth orbit, these milestones demonstrate Starlab’s dedication to building a commercial space station that can support human life and advance scientific research,” said Angela Hart, program manager for NASA’s Commercial Low Earth Orbit Development Program at the agency’s Johnson Space Center in Houston. “Both the insight shared by Starlab and the expertise shared by NASA are critical to future mission success.”
Starlab recently completed a preliminary design and safety review of its station’s architecture and systems. The company now will begin detailed design and hardware development, culminating in a critical design review later this year. Critical design reviews are an important step in a station’s development, assessing design maturity before proceeding with fabrication and assembly.
An artist’s concept of the Starlab commercial space station.StarlabStarlab also has begun construction of a full-scale, high-fidelity mockup of the station. The mockup, which will be housed in the Space Vehicle Mockup Facility at NASA Johnson, will be used for human-in-the-loop testing, during which participants perform day-in-the-life walkthroughs and evaluate the interior design, crew training, procedure development, hardware checks, and in-flight issue resolution.
In addition, Starlab completed reviews of the system design architecture, procurement plan, and Northrop Grumman Cygnus spacecraft docking system design. In 2023, Northrop Grumman teamed up with Starlab to provide cargo logistics services and engineering consultation to support the commercial space station. These reviews included design configuration updates of solar arrays, docking ports, crew quarters, and more.
NASA supports the design and development of multiple commercial space stations through funded and unfunded agreements. Following the design and development phase, NASA plans to procure services from one or more companies as part of its strategy to become one of many customers for low Earth orbit stations.

NASA Citizen Science and Your Career: Stories of Exoplanet Watch VolunteersDoing NASA Science brings many rewards. But can taking part in NASA citizen science help your career? To find out, we asked participants in NASA’s Exoplanet Watch project about their experiences. In this project, amateur astronomers work together with professionals to track planets around other stars.
First, we heard from professional software programmers. Right away, one of them told us about getting a new job through connections made in the project.
“I decided to create the exoplanet plugin, [for citizen science] since it was quite a lot of manual work to check which transits were available for your location. The exoplanet plugin and its users got me in contact with the Stellar group… Through this group, I got into contact with a company called OurSky and started working for them… the point is, I created a couple of plugins for free and eventually got a job at an awesome company.”
Another participant talked about honing their skills and growing their confidence through Exoplanet Watch.
“There were a few years when I wasn’t actively coding. However, Exoplanet Watch rekindled that spark…. Participating in Exoplanet Watch even gave me the confidence to prepare again for a technical interview at Meta—despite having been thoroughly defeated the first time I tried.”
Teachers and teaching faculty told us how Exoplanet Watch gives them the ability to better convey what scientific research is all about – and how the project motivates students!
“Exoplanet Watch makes it easy for undergraduate students to gain experience in data science and Python, which are absolutely necessary for graduate school and many industry jobs.”
“Experience with this collaborative work is a vital piece of the workforce development of our students who are seeking advanced STEM-related careers or ongoing education in STEM (Science, Technology, Engineering, & Mathematics) fields after graduation… Exoplanet Watch, in this way, is directly training NASA’s STEM workforce of tomorrow by allowing CUNY (The City University of New York) students to achieve the science goals that would otherwise be much more difficult without its resources.”
One aspiring academic shared how her participation on the science team side of the project has given her research and mentorship experience that strengthens her resume.
“I ended up joining the EpW team to contribute my expertise in stellar variability… My involvement with Exoplanet Watch has provided me with invaluable experience in mentoring a broad range of astronomy enthusiasts and working in a collaborative environment with people from around the world. … Being able to train others, interact in a team environment, and work independently are all critical skills in any work environment, but these specific experiences have also been incredibly valuable towards building my portfolio as I search for faculty positions around the USA.”
There are no guarantees, of course. What you get out of NASA citizen science depends on what you put in. But there is certainly magic to be found in the Exoplanet Watch project. As one student said:
“Help will always be found at Hogwarts, to those who need it.” Exoplanet Watch was definitely Hogwarts for me in my career as an astronomer!”
For more information about NASA and your career, check out NASA’s Surprisingly STEM series highlighting exciting and unexpected jobs at NASA, or come to NASA Career Day, a virtual event for students and educators. Participants must register by September 4, 2025. The interactive platform will be open from September 15-19, with live panels and events taking place on September 18.

Ejection Mechanism Design for the SPEED Test Architecture Challenge
The The Stratospheric Projectile Entry Experiment on Dynamics (SPEED), a two-stage stratospheric drop test architecture, is currently under development to bridge the state-of-the-art gap that many NASA flagship missions require to reduce system risk and enable more optimized designs via margin reduction. To do this, a two-stage vehicle will drop from a high-altitude balloon and use the first stage (an LV-Haack cone aeroshell) to accelerate the sub-scale test model to supersonic conditions. The onboard avionics will then release the test model into freestream flow at the proper altitude in Earth’s atmosphere for dynamic Mach scaling to the full-scale flight trajectory. SPEED leverages low-cost methods of manufacturing such as 3D printing and laser/water-jet cutting to enable 8 or more two-stage vehicles to be dropped in a single test, making the science-to-dollar density much higher than any current ground-test facility NASA has at its disposal. The goal is to develop a robust ejection system that can reliably introduce the test models into supersonic flow with a tight variance on initial condition perturbation. The separation system must be capable of handling a range of initial angle-of-attacks, keep the test model secure in the first stage during take-off and descent, and eject the test model in such a way that it does not linger behind the first stage and be affected by the resulting wake. As current ejection system designs are conceptual, complex, and untested, NASA is looking for alternative ideas that can be incorporated into the design of their next iteration of SPEED flight vehicles to increase system reliability. We are challenging the public to design innovative concepts for a separation mechanism that can be used to assess NASA and commercial reentry vehicle stability.
Award: $7,000 in total prizes

Curiosity Blog, Sols 4600-4601: Up and Over the Sand Covered Ramp NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on July 13, 2025 — Sol 4598, or Martian day 4,598 of the Mars Science Laboratory mission — at 15:24:10 UTC. NASA/JPL-CaltechWritten by Sharon Wilson Purdy, Planetary Geologist at the Smithsonian National Air and Space Museum
Earth planning date: Monday, July 14, 2025
The Curiosity rover continues to navigate through the region of Mount Sharp characterized by the boxwork terrain. After successfully completing a drive of about 34 meters over the weekend (about 112 feet), the rover parked near the edge of a smooth, sandy stretch at the base of a ridge that leads to the most prominent and complex network of boxwork structures seen so far.
Due to the lack of exposed bedrock in the immediate workspace, the science team opted to give some of the rover’s contact science instruments a break. With the dust removal tool (DRT) and APXS instruments stowed, the extra energy allowed the Mars Hand Lens Imager (MAHLI) to take high resolution images of “Playa de la Gallina” to survey the uniform, smooth surface consisting of sand and pebble-sized material.
The ChemCam and Mastcam teams scheduled several observations in this two-sol plan that further investigated the rocks and structures in our immediate vicinity and surroundings. ChemCam LIBS was used to target “El Olivo” to determine the chemistry of the bumpy textured bedrock near the rover, which was also imaged by a Mastcam stereo mosaic. Additional Mastcam stereo mosaics include fractures at “El Corral” and linear troughs at “Chapare.” Further away, ChemCam’s Remote Micro Imager (RMI) will provide insight into an intriguing section of scoured features within the Mishe Mokwa butte.
The environmental working group continues to keep an eye in the sky and planned a supra-horizon movie and a dust-devil survey as part of their ongoing monitoring campaign of the atmospheric conditions in Gale Crater.
The 21-meter-long drive (about 69 feet) at the end of this plan will maneuver the rover past the sandy ramp to the top of the main boxwork region. From here, the science team will be able to explore this fascinating area of particularly large boxwork structures. Stay tuned as Curiosity continues to climb higher and delve deeper into the geologic history of Mars!

Curiosity Blog, Sols 4597-4599: Wide Open Spaces NASA’s Mars rover Curiosity acquired this image, of the sweeping Mount Sharp vista into which the rover will drive the weekend of July 11-12, 2025, using its onboard Left Navigation Camera. Curiosity captured the image on July 11, 2025 — Sol 4596, or Martian day 4,596 of the Mars Science Laboratory mission — at 12:01:55 UTC. NASA/JPL-CaltechWritten by Michelle Minitti, MAHLI Deputy Principal Investigator, Framework
Earth planning date: Friday, July 11, 2025
Imagine this vista as the view out your office window to start your workday. Your natural tendency would be to grab your camera and photograph as much of the view as possible. Curiosity was lucky enough to find herself in this situation today after a successful drive of about 61 meters (about 200 feet) on Wednesday, and the science team operating Curiosity wasted no time papering the scene with mosaics.
Between Mastcam and ChemCam, we planned 105 images across the scene. Those images will capture the structures underpinning the boxwork ridges we are driving toward, smaller-scale fractures in the near field that might be related to the boxwork ridges, and the back side of a ridge we recently studied in detail, “Volcán Peña Blanca.” Together, the images will help us understand the geologic history of the area that hosts the boxwork ridges, and what conditions existed in this part of Mount Sharp to support their formation.
We did not neglect the rocks directly in front of the rover as we gazed at our surroundings. Indeed, the bedrock near the rover was nearly uniformly packed with small (less than 1 centimeter, or 0.39 inches) rounded nodules, a characteristic we have not seen for awhile. MAHLI will image three different instances of the nodules while APXS and ChemCam will each analyze two different targets to understand the chemistry of the nodules and the bedrock hosting them.
REMS, RAD, and DAN will continue to monitor the Martian environment and subsurface throughout the weekend. Additionally, we planned multiple observations of dust devils, the amount of dust in the atmosphere, and clouds including a cloud movie timed to match the overflight of the CASSIS instrument. Our drive will take us to the foot of the smooth slope seen in the distance of the above image. That slope is the ramp we will take to the top of a big boxwork structure, where surely other delightful vistas await.

NASA SCoPE Summer Symposium Celebrates Early Career Scientists and Cross-Team CollaborationFrom June 16–18, 2025, the NASA Science Mission Directorate Community of Practice for Education (SCoPE) Summer Symposium brought together a community of scientists, educators, and outreach professionals to celebrate and strengthen NASA’s commitment to developing its workforce and broadening participation in science.
NASA SCoPE is a NASA-funded initiative at Arizona State University that connects early career scientists with NASA Science Activation (SciAct) program teams to build capacity in science communication, community engagement, and educational outreach. Through targeted support like Seed Grants, Travel Grants, and Mission Liaison opportunities, SCoPE equips scientists with the skills and networks needed to meaningfully engage the public with NASA science.
Held in collaboration with key SciAct teams—including Infiniscope, Co-creating with Communities, NASA’s Community College Network, and NASA’s Universe of Learning—the 2025 symposium highlighted the incredible impact of SCoPE over the past four and a half years. The program has financially supported more than 100 early career scientists across a growing network of nearly 1,000 participants.
Over the course of the three-day event, 23 awardees of SCoPE Seed Grants, Travel Grants, and Mission Liaison Grants came together to share their work, connect across disciplines, and explore new avenues for collaboration. Twelve Seed Grant awardees presented their projects, illustrating the transformative power of partnerships with SciAct teams. Highlights included learning how to write for young audiences through mentorship from NASA eClips in support of the children’s book ‘Blai and Zorg Explore the Moon’, designed for elementary learners; a collaborative effort between ‘Lost City, Icy Worlds’ and OpenSpace that evolved into long-term networking and visualization opportunities; and an Antarctic research project that, through collaboration with the Ocean Community Engagement and Awareness using NASA Earth Observations and Science (OCEANOS) project and Infiniscope, both expanded training opportunities for expedition guides and brought polar science to Puerto Rican high school summer interns.
Beyond formal sessions, the symposium embraced community building through shared meals, informal networking, and hands-on experiences like a 3D planetarium show using OpenSpace software, a telescope demonstration with 30 high school students, and a screening of NASA’s Planetary Defenders documentary. Workshop topics addressed the real-world needs of early career professionals, including grant writing, logic model development, and communicating with the media.
Survey responses revealed that 95% of attendees left with a stronger sense of belonging to a community of scientists engaged in outreach. Participants reported making valuable new connections—with peers, mentors, and potential collaborators—and left inspired to try new approaches in their own work, from social media storytelling to designing outreach for hospital patients or other specialized audiences.
As one participant put it, “Seeing others so passionate about Science Communication inspired me to continue doing it in different ways… it feels like the start of a new wave.” Another attendee remarked, “I want to thank the entire team for SCoPE to even exist. It is an incredible team/program/resource and I can’t even imagine the amount of work, dedication and pure passion that has gone into this entire project over the years. Although I only found SCoPE very recently, I feel like it has been incredibly helpful in my scientific journey and I only wish I had learned of the program sooner. Thank you to the entire team for what was a truly educational and inspirational workshop, and the wonderful community that SCoPE has fostered.”
This successful event was made possible through the dedication of NASA SciAct collaborators and the leadership of SciAct Program Manager Lin Chambers, whose continued support of early career engagement through SCoPE has created a growing, connected community of science communicators. The SCoPE Summer Symposium exemplifies how cross-team collaboration and community-centered design can effectively amplify the reach of NASA science.
