During the Artemis II mission to the Moon, NASA astronauts Reid Wiseman and Victor Glover will take control and manually fly Orion for the first time, evaluating the handling qualities of the spacecraft during a key test called the proximity operations demonstration. This is how to fly Orion.

On NASA’s Artemis II test flight, the first crewed mission under the agency’s Artemis campaign, astronauts will take the controls of the Orion spacecraft and periodically fly it manually during the flight around the Moon and back. The mission provides the first opportunity to ensure the spacecraft operates as designed with humans aboard, ahead of future Artemis missions to the Moon’s surface.

The first key piloting test, called the proximity operations demonstration, will take place after the four crew members — NASA’s Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen — are safely in space, about three hours into the mission. To evaluate the spacecraft’s manual handling qualities, the crew will pilot Orion to approach and back away from the detached upper stage of the SLS (Space Launch System) rocket.

Crew members participating in the demonstration will use two different controllers, called rotational and translational hand controllers, to steer the spacecraft. Three display screens provide the astronauts with data, and another device, called the cursor control device, allows the crew to interact with the displays.

Astronauts will use the rotational hand controller (RHC), gripped in the right hand, to rotate the spacecraft. It controls Orion’s attitude, or the direction the spacecraft is pointing. If the crew wants to point Orion’s nose left, the RHC is twisted left – for nose right, they will twist the RHC right. Similarly, the RHC can control the nose to pitch up or down or roll right or left.

“On Artemis II, most of the time the spacecraft will fly autonomously, but having humans aboard is a chance to help with future mission success,” said Reid Wiseman. “If something goes wrong, a crewmember can jump on the controls and help fix the problem. One of our big goals is to check out this spacecraft and have it completely ready for our friends on Artemis III.”

The commander and pilot seats are each equipped with a rotational hand controller (RHC), gripped in the right hand, to rotate the spacecraft. It controls Orion’s attitude, or the direction the spacecraft is pointing. If the crew wants to point Orion’s nose left, the RHC is twisted left — for nose right, they will twist the RHC right. Similarly, the RHC can control the nose to pitch up or down or roll right or left.

The translational hand controller (THC), located to the right or left of the display screens, will move Orion from one point to another. To move the spacecraft forward, the crew pushes the controller straight in — to back up, they will pull the controller out. And similarly, the controller can be pushed up or down and left or right to move in those directions.

When the crew uses one of the controllers, their command is detected by Orion’s flight software, run by the spacecraft’s guidance, navigation, and control system. The flight software was designed, developed, and tested by Orion’s main contractor, Lockheed Martin.

To move the spacecraft forward, the crew pushes the controller straight in – to back up, they will pull the controller out. And similarly, the controller can be pushed up or down and left or right to move in those directions.

“We’re going to perform flight test objectives on Artemis II to get data on the handling qualities of the spacecraft and how well it maneuvers,” said Jeffrey Semrau, Lockheed Martin’s manual controls flight software lead for Artemis missions. “We’ll use that information to upgrade and improve our control systems and facilitate success for future missions.”

Depending on what maneuver the pilot has commanded, Orion’s software determines which of its 24 reaction control system thrusters to fire, and when. These thrusters are located on Orion’s European-built service module. They provide small amounts of thrust in any direction to steer the spacecraft and can provide torque to allow rotation control.

The cursor control device allows the crew to interact with the three display screens that show spacecraft data and information. This device allows the crew to interact with Orion even under the stresses of launch or entry when gravitational forces can prevent them from physically reaching the screens.

Next to Orion’s displays, the spacecraft also has a series of switches, toggles, and dials on the switch interface panel. Along with switches the crew will use during normal mission operations, there is also a backup set of switches they can use to fly Orion if a display or hand controller fails.

“This flight test will simulate the flying that we would do if we were docking to another spacecraft like our lander or to Gateway, our lunar space station,” said Victor Glover. “We’re going to make sure that the vehicle flies the way that our simulators approximate. And we’re going to make sure that it’s ready for the more complicated missions ahead.”

The approximately 10-day Artemis II flight will test NASA’s foundational human deep space exploration capabilities, the SLS rocket, Orion spacecraft, and supporting ground systems, for the first time with astronauts and will pave the way for lunar surface missions.

Preparations for Next Moonwalk Simulations Underway (and Underwater) A massive hotspot — larger the Earth’s Lake Superior — can be seen just to the right of Io’s south pole in this annotated image taken by the JIRAM infrared imager aboard NASA’s Juno on Dec. 27, 2024, during the spacecraft’s flyby of the Jovian moon. NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM

Even by the standards of Io, the most volcanic celestial body in the solar system, recent events observed on the Jovian moon are extreme.

Scientists with NASA’s Juno mission have discovered a volcanic hot spot in the southern hemisphere of Jupiter’s moon Io. The hot spot is not only larger than Earth’s Lake Superior, but it also belches out eruptions six times the total energy of all the world’s power plants. The discovery of this massive feature comes courtesy of Juno’s Jovian Infrared Auroral Mapper (JIRAM) instrument, contributed by the Italian Space Agency.

“Juno had two really close flybys of Io during Juno’s extended mission,” said the mission’s principal investigator, Scott Bolton of the Southwest Research Institute in San Antonio. “And while each flyby provided data on the tormented moon that exceeded our expectations, the data from this latest — and more distant — flyby really blew our minds. This is the most powerful volcanic event ever recorded on the most volcanic world in our solar system — so that’s really saying something.”

The source of Io’s torment: Jupiter. About the size of Earth’s Moon, Io is extremely close to the mammoth gas giant, and its elliptical orbit whips it around Jupiter once every 42.5 hours. As the distance varies, so does the planet’s gravitational pull, which leads to the moon being relentlessly squeezed. The result: immense energy from frictional heating that melts portions of Io’s interior, resulting in a seemingly endless series of lava plumes and ash venting into its atmosphere from the estimated 400 volcanoes that riddle its surface.

Close Flybys

Designed to capture the infrared light (which isn’t visible to the human eye) emerging from deep inside Jupiter, JIRAM probes the gas giant’s weather layer, peering 30 to 45 miles (50 to 70 kilometers) below its cloud tops. But since NASA extended Juno’s mission, the team has also used the instrument to study the moons Io, Europa, Ganymede, and Callisto.

Images of Io captured in 2024 by the JunoCam imager aboard NASA’s Juno show signif-icant and visible surface changes (indicated by the arrows) near the Jovian moon’s south pole. These changes occurred between the 66th and 68th perijove, or the point during Juno’s orbit when it is closest to Jupiter.Image data: NASA/JPL-Caltech/SwRI/MSSS Image processing by Jason Perry

During its extended mission, Juno’s trajectory passes by Io every other orbit, flying over the same part of the moon each time. Previously, the spacecraft made close flybys of Io in December 2023 and February 2024, getting within about 930 miles (1,500 kilometers) of its surface. The latest flyby took place on Dec. 27, 2024, bringing the spacecraft within about 46,200 miles (74,400 kilometers) of the moon, with the infrared instrument trained on Io’s southern hemisphere.

Io Brings the Heat

“JIRAM detected an event of extreme infrared radiance — a massive hot spot — in Io’s southern hemisphere so strong that it saturated our detector,” said Alessandro Mura, a Juno co-investigator from the National Institute for Astrophysics in Rome. “However, we have evidence what we detected is actually a few closely spaced hot spots that emitted at the same time, suggestive of a subsurface vast magma chamber system. The data supports that this is the most intense volcanic eruption ever recorded on Io.”

The JIRAM science team estimates the as-yet-unnamed feature spans 40,000 square miles (100,000 square kilometers). The previous record holder was Io’s Loki Patera, a lava lake of about 7,700 square miles (20,000 square kilometers). The total power value of the new hot spot’s radiance measured well above 80 trillion watts.

Picture This

The feature was also captured by the mission’s JunoCam visible light camera. The team compared JunoCam images from the two previous Io flybys with those the instrument collected on Dec. 27. And while these most recent images are of lower resolution since Juno was farther away, the relative changes in surface coloring around the newly discovered hot spot were clear. Such changes in Io’s surface are known in the planetary science community to be associated with hot spots and volcanic activity.

An eruption of this magnitude is likely to leave long-lived signatures. Other large eruptions on Io have created varied features, such as pyroclastic deposits (composed rock fragments spewed out by a volcano), small lava flows that may be fed by fissures, and volcanic-plume deposits rich in sulfur and sulfur dioxide.

Juno will use an upcoming, more distant flyby of Io on March 3 to look at the hot spot again and search for changes in the landscape. Earth-based observations of this region of the moon may also be possible.  

“While it is always great to witness events that rewrite the record books, this new hot spot can potentially do much more,” said Bolton. “The intriguing feature could improve our understanding of volcanism not only on Io but on other worlds as well.”

Crews conduct a solar array deployment test on the spacecraft of NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites at Astrotech Space Operations located inside Vandenberg Space Force Base in California on Tuesday, Jan. 21, 2025.USSF 30th Space Wing/Antonio Ramos

Technicians supporting NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission deployed and tested the spacecraft’s solar arrays at the Astrotech Space Operations processing facility at Vandenberg Space Force Base in California ahead of its launch next month.

The arrays, essential for powering instruments and systems, mark another milestone in preparing PUNCH for its mission to study the Sun’s outer atmosphere as it transitions into the solar wind. Technicians performed the tests in a specialized cleanroom environment to prevent contamination and protect the sensitive equipment.

Comprised of four suitcase-sized satellites working together as a constellation, PUNCH will capture continuous 3D images of the Sun’s corona and the solar wind’s journey into the solar system. Led by the Southwest Research Institute (SwRI) for NASA, the mission aims to deepen our understanding of the Sun and solar wind and how they affect humanity’s technology on Earth and our continued exploration of the solar system.

Successful solar array testing brings the spacecraft another step toward readiness for launch. The agency’s PUNCH mission is targeting liftoff as a rideshare with NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) on a SpaceX Falcon 9 rocket from Vandenberg’s Space Launch Complex 4E no earlier than Thursday, Feb. 27.

Reducing reliance on resupply missions

Resupply of life support elements such as air, water, food, clothing, and hygiene items will be impractical on missions to the Moon and beyond. This research assessed current use and resupply of these elements on the International Space Station and outlines technologies needed for sustained human presence in space, such as 3D printing maintenance parts, systems for laundering clothes, and improved recovery and recycling of elements.

Researchers analyzed the types and mass of elements supplied from Earth to the station and astronaut feedback from various studies and interviews. The paper also used data from ISS Internal Environments, a wide-ranging investigation that samples various aspects of the space station environment in support of many types of research.

Verifying a technique for analyzing emulsions

This paper presents a review of examining the behavior of emulsions (suspensions of particles in a liquid) in microgravity using a technique called diffusing wave spectroscopy. Results offer insights that could support development of technologies to improve living environments and foods for crew members on future missions.

FSL Soft Matter Dynamics – PASTA studied the dynamics of droplets in emulsions. Accurate study and characterization of the effects of additives on emulsion stability is possible in microgravity. Emulsions have applications in foods, cosmetics, pharmaceuticals, fuels, paints and coatings, chemical processing, and materials.

EEG measurements and predicting cognitive changes in spaceflight

Researchers used an electroencephalogram (EEG) to measure brainwave activity during a relaxed, wakeful state in crew members and found no significant differences before, during, and after flight. These types of measurements could serve as biomarkers of brain health status, helping to predict changes in cognitive performance and the need for prevention and countermeasure strategies during future missions.

Studies have shown that spaceflight can affect key cognitive and motor skills such as task management, attention, and movement speed and accuracy. Neurowellness in Space Ax-1 tested using a portable, easy to use EEG headset to measure ongoing and task-related brain activity in microgravity. The data could help predict and monitor neural changes on future space missions.

Astronomers have taken a crucial step in showing that the most massive black holes in the universe can create their own meals. Data from NASA’s Chandra X-ray Observatory and the Very Large Telescope (VLT) provide new evidence that outbursts from black holes can help cool down gas to feed themselves.

This study was based on observations of seven clusters of galaxies. The centers of galaxy clusters contain the universe’s most massive galaxies, which harbor huge black holes with masses ranging from millions to tens of billions of times that of the Sun. Jets from these black holes are driven by the black holes feasting on gas.

These images show two of the galaxy clusters in the study, the Perseus Cluster and the Centaurus Cluster. Chandra data represented in blue reveals X-rays from filaments of hot gas, and data from the VLT, an optical telescope in Chile, shows cooler filaments in red.

The results support a model where outbursts from the black holes trigger hot gas to cool and form narrow filaments of warm gas. Turbulence in the gas also plays an important role in this triggering process.

According to this model, some of the warm gas in these filaments should then flow into the centers of the galaxies to feed the black holes, causing an outburst. The outburst causes more gas to cool and feed the black holes, leading to further outbursts.

This model predicts there will be a relationship between the brightness of filaments of hot and warm gas in the centers of galaxy clusters. More specifically, in regions where the hot gas is brighter, the warm gas should also be brighter. The team of astronomers has, for the first time, discovered such a relationship, giving critical support for the model.

This result also provides new understanding of these gas-filled filaments, which are important not just for feeding black holes but also for causing new stars to form. This advance was made possible by an innovative technique that isolates the hot filaments in the Chandra X-ray data from other structures, including large cavities in the hot gas created by the black hole’s jets.

The newly found relationship for these filaments shows remarkable similarity to the one found in the tails of jellyfish galaxies, which have had gas stripped away from them as they travel through surrounding gas, forming long tails. This similarity reveals an unexpected cosmic connection between the two objects and implies a similar process is occurring in these objects.

This work was led by Valeria Olivares from the University of Santiago de Chile, and was published Monday in Nature Astronomy. The study brought together international experts in optical and X-ray observations and simulations from the United States, Chile, Australia, Canada, and Italy. The work relied on the capabilities of the MUSE (Multi Unit Spectroscopic Explorer) instrument on the VLT, which generates 3D views of the universe.

NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

Visual Description

This release features composite images shown side-by-side of two different galaxy clusters, each with a central black hole surrounded by patches and filaments of gas. The galaxy clusters, known as Perseus and Centaurus, are two of seven galaxy clusters observed as part of an international study led by the University of Santiago de Chile.

In each image, a patch of purple with neon pink veins floats in the blackness of space, surrounded by flecks of light. At the center of each patch is a glowing, bright white dot. The bright white dots are black holes. The purple patches represent hot X-ray gas, and the neon pink veins represent filaments of warm gas. According to the model published in the study, jets from the black holes impact the hot X-ray gas. This gas cools into warm filaments, with some warm gas flowing back into the black hole. The return flow of warm gas causes jets to again cool the hot gas, triggering the cycle once again.

While the images of the two galaxy clusters are broadly similar, there are significant visual differences. In the image of the Perseus Cluster on the left, the surrounding flecks of light are larger and brighter, making the individual galaxies they represent easier to discern. Here, the purple gas has a blue tint, and the hot pink filaments appear solid, as if rendered with quivering strokes of a paintbrush. In the image of the Centaurus Cluster on the right, the purple gas appears softer, with a more diffuse quality. The filaments are rendered in more detail, with feathery edges, and gradation in color ranging from pale pink to neon red.

Sols 4348-4349: Smoke on the Water NASA’s Mars rover Curiosity created this composite image from its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm. An onboard process, focus merging, makes a composite of images of the same target — acquired at different focus positions — to bring all (or, as many as possible) features into focus in a single image. Curiosity performed this merge on Oct. 27, 2024, sol 4346 (Martian day 4,346) of the Mars Science Laboratory Mission, at 15:45:47 UTC. NASA/JPL-Caltech/MSSS

Earth planning date: Monday, Oct. 28, 2024

Before the science team starts planning, we first look at the latest Navcam image downlinked from Curiosity to see where the rover is located. It can be all too easy to get lost in the scenery of the Navcam and find new places in the distance we want to drive towards, but there’s so much beauty in the smaller things. Today I’ve chosen to show a photo from Curiosity’s hand lens camera, MAHLI, that takes photos so close that we can see the individual grains of the rock.

The planning day usually starts by thinking about these smaller features: What rocks are the closest to the rover? What can we shoot with our laser? What instruments can we use to document these features? Today we planned two sols, and the focus of the close-up contact science became a coating of material that in some image stretches looks like a deep-purple color.

We planned lots of activities to characterize this coating including use of the dust removal tool (DRT) and the APXS instrument on a target called “Reds Meadow.” This target will also be photographed by the MAHLI instrument. The team planned a ChemCam LIBS target on “Midge Lake” as well as a passive ChemCam target on “Primrose Lake” to document this coating with a full suite of instruments. Mastcam will then document the ChemCam LIBS target Midge Lake, and take a mosaic of the vertical faces of a few rocks near to the rover called “Peep Sight Peak” to observe the sedimentary structures here. Mastcam will also take a mosaic of “Pinnacle Ridge,” an area seen previously by the rover, from a different angle. ChemCam is rounding off the first sol with two long-distance RMI mosaics to document the stratigraphy of two structures we are currently driving between: Texoli butte and the Gediz Vallis channel.

In the second sol of the plan, after driving about 20 meters (about 66 feet), Curiosity will be undertaking some environmental monitoring activities before an AEGIS activity that automatically selects a LIBS target in our new workspace prior to our planning on Wednesday morning.

How it started versus how it’s going for astronaut Nick Hague with ISS Ham Radio on the space station.

Since November 2000, crew members like Hague have used ham radio to communicate with people on Earth through this educational program, also known as Amateur Radio on the International Space Station or ARISS. So far, there have been more than 1,700 events, directly engaging students and listeners from 49 U.S. states, 63 countries, and all seven continents. Students study the space station, radio waves, amateur radio technology, and related topics before their call from space, which encourages interest in STEM.

Now through Nov 17, 2024, ARISS is accepting applications from formal and informal educational institutions and organizations that want to host events in summer or fall of 2025. There is no charge for these calls from space, although host locations may incur some equipment-related costs. Local amateur radio clubs help hosts prepare for their contacts.

In alignment with the month’s national theme, “Access to Good Jobs for All,” the program highlighted the perspectives of people with disabilities in the workplace as they navigate the work lifecycle – from applying, to onboarding, career growth and advancement, and day-to-day engagements.

The event began with Marshall Associate Director Roger Baird welcoming NASA team members.

“NASA is dedicated to inclusive hiring practices and providing pathways for good jobs and career success for all employees, including workers with disabilities,” Baird said. “Some ways we do this is through targeted recruitment of qualified individuals with disabilities through accessible vacancy announcements, outreach to students with disabilities, and community partnerships.”

NASA also utilizes Schedule A Authority, a non-competitive Direct Hiring Authority to hire people with disabilities without competition.

Baird introduced event moderator Joyce Meier, logistics manager at Marshall, who welcomed panelists Casey Denham, Kathy Clark, Paul Spann, and Paul Sullivan, all NASA team members. The panelists from the disability community discussed their work lifecycles, lessons learned in the workplace, and shared a demonstration on colorblindness and its impact.

Denham discussed some of the best practices for onboarding employees with neurodiversity, a term used to describe people whose brains develop or work differently than the typical brain.

Clark talked about what can be done to continue raising awareness and advocating for disability rights. She said NASA empowers its workforce with knowledge so they can be informed allies to team members with disabilities and foster a safe and inclusive working environment. 

Spann gave insight into practical steps employers can take to accommodate candidates with deafness, and Sullivan spoke about some key considerations NASA managers should keep in mind to make the job application process more accessible to candidates with low vision.

Guest speaker Chip Dobbs, supply management specialist at Marshall, talked about his personal experiences with being deaf. Dobbs has worked at NASA for 29 years and said he has never let his disability hold him back, but instead uses it as a gateway to inspire and connect with others.

The event ended with closing remarks from Tora Henry, director of the Office of Diversity and Equal Opportunity at Marshall. The virtual event placed importance on planning for NASA’s future by promoting equality and addressing the barriers people with disabilities face in the workplace. 

“As we celebrate National Disability Employment Awareness Month, keep in mind that NASA’s mission of exploring the unknown and pushing the boundaries of human potential requires the contributions of every mind, skill set, and perspective,” Baird said. “Our commitment to inclusivity ensures that no talent goes untapped, and no idea goes unheard because together, we’re not just reaching for the stars, we’re showing the world what’s possible when everyone has a seat at the table.”

A recording of the event is available here. Learn more about NASA’s agencywide resources for individuals with disabilities as well as the agency’s Disability Employment Program.

Take 5 with Brooke Rhodes

By Wayne Smith

When human exploration of Mars becomes a reality and more than just the stuff of science fiction, Brooke Rhodes will be eager to investigate what astronauts discover on the Red Planet.

From listening to her talk about her work as an engineer at NASA’s Marshall Space Flight Center, it’s easy to grasp her excitement about the future of human space exploration and NASA’s Moon to Mars architecture.

Brooke Rhodes is currently on detail as the branch chief of the Avionics and Software Ground Systems Test Branch at NASA’s Marshall Space Flight Center. Working in the Instrument Development, Integration and Test Branch for the past seven years, she’s been responsible for the integration and testing of International Space Station payloads. NASA

“I can’t wait for the Mars rovers to have some human company,” said Rhodes, who recently began a detail as the chief of Marshall’s Avionics and Software Ground Systems Test Branch. “I need to know if we can grow Mark Watney (of The Martian movie fame) quantities of potatoes up there. Everything we do to prepare to return humans to the Moon and establish a presence in deep space is building toward putting boots on Mars. It’s an honor and a privilege to be even a small part of it.”

Rhodes also appreciates the responsibility she takes on in any form in NASA’s exploration missions to benefit humanity. After all, she has worked on hardware for the International Space Station and has had supporting roles for the Mars Ascent Vehicle and Artemis missions.

“We at Marshall hold an incredible amount of responsibility: responsibility for the welfare of the crew on the space station, responsibility for the welfare of the crew on the Artemis missions, and even the welfare of humanity through the responsibility we have for science on the station and elsewhere,” said Rhodes, who is from Petal, Mississippi, and has worked at Marshall for seven years. “When your missions are as critical as ours, it’s nearly impossible to not be motivated.”

Now, on to Mars.

Question: What is your position and what are your primary responsibilities?

Rhodes: I recently began the detail as the branch chief of the Avionics and Software Ground Systems Test Branch, ES53. Our branch is primarily responsible for the development of hardware-in-the-loop and software development facilities for the Artemis and MAV (Mars Ascent Vehicle) missions. My home organization is ES61, the Instrument Development, Integration and Test Branch, where I’ve been responsible for the integration and testing of International Space Station payloads for the past several years.

Question: What has been the proudest moment of your career and why?

Rhodes: One really cool moment that sticks out was the first time I saw hardware I had been responsible for being used in space. I spent several years as the integration and test lead of the Materials Science Research Rack (MSRR) Sample Cartridge Assemblies (SCAs) and we shipped our first batch of SCAs to the space station in 2018. That shipment was the culmination of years of intense effort and teamwork, so to see them onboard and about to enable materials science was an incredible feeling. There was a moment in particular that felt a bit surreal: prior to our SCA shipment the crew discovered they were missing a couple of fasteners from the onboard furnace, so we had those shipped to us from Europe and I packed them into the SCA flight foam before they shipped to the launch site. The next time I saw those fasteners they were being held up to a camera by one of the crew members, asking if those were the ones they needed for the furnace. Putting fasteners into foam didn’t take much effort, but what it represented was much bigger: being a small part of an international effort to enable science off the Earth, for the Earth, was an incredible moment I’ll carry with me for the rest of my career.

Question: Who or what inspired you to pursue an education/career that led you to NASA and Marshall?

Rhodes: I had a couple of lightbulb moments my junior year of high school that eventually set me on my current career path. I very specifically recall sitting in my physics I class and learning how to calculate the planetary motion of Jupiter and thinking I had never learned about anything cooler. Even then, though, NASA didn’t really enter my thoughts. Growing up, working for NASA didn’t even occur to me as something people could actually do – being a “rocket scientist” was just an abstract concept people threw around to indicate something was difficult.

That changed later when the same teacher who had been teaching us planetary motion took us on a field trip to Kennedy Space Center. The tour guide showing us around the Vehicle Assembly Building was a young employee who said he had majored in aerospace engineering at the University of Tennessee. That was the second lightbulb moment: here was a young person from the Southeast, just like me, who had done something tangible in order to work for NASA. That seemed easy enough, so I decided to major in aerospace engineering at Mississippi State and one day work for NASA. That turned out to not be easy, but definitely doable.

While at Mississippi State, I was able to complete three NASA internships, one at the Jet Propulsion Laboratory and two at Marshall. Eventually, I was hired on full-time at NASA’s Johnson Space Center, but wound up making my way back to Marshall, where I’ve been ever since. There’s no place on the planet better for enthusiasts of both aerospace engineering and football.

Interestingly, my physics I teacher’s name was Mrs. Rhodes, and I used to joke with my classmates that I wanted to be Mrs. Rhodes when I grew up. I didn’t actually mean that literally, but then I married Matthew Rhodes and did, indeed, become Mrs. Rhodes.

Question: What advice do you have for employees early in their NASA career or those in new leadership roles?

Rhodes: Scary is good. If you aren’t stepping out of your comfort zone you probably aren’t growing, and if you’re experiencing imposter syndrome, you’re probably the right person for the job.

Question: What do you enjoy doing with your time while away from work?

Rhodes: While away from work I tend to invest too much of my mental wellbeing into football. To recover from the stresses of work and my football teams being terrible, I like to explore National Parks. The U.S. has some of the most diverse scenery anywhere in the world, and I love getting outside and exploring it.

Planets Beware: NASA Unburies Danger Zones of Star Cluster

Most stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets.

A team of astronomers used NASA’s Chandra X-ray Observatory, in combination with ultraviolet, optical, and infrared data, to show where some of the most treacherous places in a star cluster may be, where planets’ chances to form are diminished.

In this new composite image, Chandra data (purple) shows the diffuse X-ray emission and young stars in Cygnus OB2, and infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue, and cyan) reveals young stars and the cooler dust and gas throughout the region.X-ray: NASA/CXC/SAO/J. Drake et al, IR: NASA/JPL-Caltech/Spitzer; Image Processing: NASA/CXC/SAO/N. Wolk

The target of the observations was Cygnus OB2, which is the nearest large cluster of stars to our Sun – at a distance of about 4,600 light-years. The cluster contains hundreds of massive stars as well as thousands of lower-mass stars. The team used long Chandra observations pointing at different regions of Cygnus OB2, and the resulting set of images were then stitched together into one large image.

The deep Chandra observations mapped out the diffuse X-ray glow in between the stars, and they also provided an inventory of the young stars in the cluster. This inventory was combined with others using optical and infrared data to create the best census of young stars in the cluster.

In a new composite image, the Chandra data (purple) shows the diffuse X-ray emission and young stars in Cygnus OB2, and infrared data from NASA’s now-retired Spitzer Space Telescope (red, green, blue, and cyan) reveals young stars and the cooler dust and gas throughout the region.

In these crowded stellar environments, copious amounts of high-energy radiation produced by stars and planets are present. Together, X-rays and intense ultraviolet light can have a devastating impact on planetary disks and systems in the process of forming.

Planet-forming disks around stars naturally fade away over time. Some of the disk falls onto the star and some is heated up by X-ray and ultraviolet radiation from the star and evaporates in a wind. The latter process, known as “photoevaporation,” usually takes between five and 10 million years with average-sized stars before the disk disappears. If massive stars, which produce the most X-ray and ultraviolet radiation, are nearby, this process can be accelerated.

The researchers using this data found clear evidence that planet-forming disks around stars indeed disappear much faster when they are close to massive stars producing a lot of high-energy radiation. The disks also disappear more quickly in regions where the stars are more closely packed together.

For regions of Cygnus OB2 with less high-energy radiation and lower numbers of stars, the fraction of young stars with disks is about 40%. For regions with more high-energy radiation and higher numbers of stars, the fraction is about 18%. The strongest effect – meaning the worst place to be for a would-be planetary system – is within about 1.6 light-years of the most massive stars in the cluster.

A separate study by the same team examined the properties of the diffuse X-ray emission in the cluster. They found that the higher-energy diffuse emission comes from areas where winds of gas blowing away from massive stars have collided with each other. This causes the gas to become hotter and produce X-rays. The less energetic emission probably comes from gas in the cluster colliding with gas surrounding the cluster.

Two separate papers describing the Chandra data of Cygnus OB2 are available. The paper about the planetary danger zones, led by Mario Giuseppe Guarcello (National Institute for Astrophysics in Palermo, Italy), appeared in the November 2023 issue of the Astrophysical Journal Supplement Series, and is available here. The paper about the diffuse emission, led by Juan Facundo Albacete-Colombo (University of Rio Negro in Argentina) was published in the same issue of Astrophysical Journal Supplement, and is available here.

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.

NASA’s Jet Propulsion Laboratory (JPL) managed the Spitzer Space Telescope mission for the agency’s Science Mission Directorate until the mission was retired in January 2020. Science operations were conducted at the Spitzer Science Center at Caltech. Spacecraft operations were based at Lockheed Martin Space in Littleton, Colorado. Data are archived at the Infrared Science Archive operated by IPAC at Caltech. Caltech manages JPL for NASA.

NASA Begins New Deployable Solar Array Tech Demo on Pathfinder Spacecraft

NASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft’s systems including its on-board electronics as well as the payload’s support systems such as the small onboard camera. Shown is a test image of Earth taken by the payload camera, shortly after PTD-4 reached orbit. This camera will continue photographing the technology demonstration during the mission.

Payload operations are now underway for the primary objective of the PTD-4 mission – the demonstration of a new power and communications technology for future spacecraft. The payload, a deployable solar array with an integrated antenna called the Lightweight Integrated Solar Array and anTenna, or LISA-T, has initiated deployment of its central boom structure. The boom supports four solar power and communication arrays, also called petals. Releasing the central boom pushes the still-stowed petals nearly three feet away from the spacecraft bus. The mission team currently is working through an initial challenge to get LISA-T’s central boom to fully extend before unfolding the petals and beginning its power generation and communication operations.

Small spacecraft on deep space missions require more electrical power than what is currently offered by existing technology. The four-petal solar array of LISA-T is a thin-film solar array that offers lower mass, lower stowed volume, and three times more power per mass and volume allocation than current solar arrays. The in-orbit technology demonstration includes deployment, operation, and environmental survivability of the thin-film solar array.  

“The LISA-T experiment is an opportunity for NASA and the small spacecraft community to advance the packaging, deployment, and operation of thin-film, fully flexible solar and antenna arrays in space. The thin-film arrays will vastly improve power generation and communication capabilities throughout many different mission applications,” said John Carr, deputy center chief technologist at NASA’s Marshall Space Flight Center. “These capabilities are critical for achieving higher value science alongside the exploration of deep space with small spacecraft.”

NASA teams are testing a key technology demonstration known as LISA-T, short for the Lightweight Integrated Solar Array and anTenna. It’s a super compact, stowable, thin-film solar array that when fully deployed in space, offers both a power generation and communication capability for small spacecraft. LISA-T’s orbital flight test is part of the Pathfinder Technology Demonstrator series of missions. (NASA)

The Pathfinder Technology Demonstration series of missions leverages a commercial platform which serves to test innovative technologies to increase the capability of small spacecraft. Deploying LISA-T’s thin solar array in the harsh environment of space presents inherent challenges such as deploying large highly flexible non-metallic structures with high area to mass ratios. Performing experiments such as LISA-T on a smaller, lower-cost spacecraft allows NASA the opportunity to take manageable risk with high probability of great return. The LISA-T experiment aims to enable future deep space missions with the ability to acquire and communicate data through improved power generation and communication capabilities on the same integrated array.

The PTD-4 small spacecraft is hosting the in-orbit technology demonstration called LISA-T. The PTD-4 spacecraft deployed into low Earth orbit from SpaceX’s Transporter-11 rocket, which launched from Space Launch Complex 4E at Vandenberg Space Force Base in California on Aug. 16. Marshall designed and built the LISA-T technology as well as LISA-T’s supporting avionics system. NASA’s Small Spacecraft Technology program, based at NASA’s Ames Research Center and led by the agency’s Space Technology Mission Directorate, funds and manages the PTD-4 mission as well as the overall Pathfinder Technology Demonstration mission series. Terran Orbital Corporation of Irvine, California, developed and built the PTD-4 spacecraft bus, named Triumph.

NASA SPoRT’s Streamflow-AI Helps with Flood Preparedness in Texas

By Paola Pinto

For more than two decades, the NASA Short-term Prediction Research and Transition Center (SPoRT) within the NASA Earth Science Office at Marshall Space Flight Center has been at the forefront of developing and maintaining decision-making tools for meteorological predictions.

This image represents the first instance of predictions getting into moderate flooding in Pine Island Bayou. At 14 feet (start of the moderate flooding category), Cooks Lake Road becomes unsafe for most vehicles. NASA

Jonathan Brazzell, a service hydrologist at the National Weather Service (NWS) office in Lake Charles, Louisiana, highlighted a recent example of SPoRT’s impact while he was doing forecasting for Texas streams.

Brazzell, who manages the South Texas and South Louisiana regions, emphasized the practical applications and significant impacts of the Machine Learning model developed by NASA SPoRT to predict future stream heights, known as the SPoRT Streamflow A.I. During a heavy rainfall event this past spring, he noted the challenge of forecasting flooding beyond 48 hours. SPoRT has worked closely with the NWS offices to develop a machine learning tool capable of predicting river flooding beyond two days and powered by the SPoRT Land Information System.

“Previously, we relied on actual gauge information and risk assessments based on predicted precipitation,” Brazzell said. “Now, with this machine learning, we have a modeling tool that provides a much-needed predictive capability.”

During forecasted periods of heavy precipitation from early to mid-May, Brazzell monitored potential flooding events and their magnitude using NASA SPoRT’s Streamflow-AI, which provided essential support to the Pine Island Bayou and Big Cow Creek communities in south Texas.

Streamflow A.I. enabled local authorities to provide advance notice, allowing residents to prepare adequately for the event. Due to the benefit of three to seven-day flood stage predictions, the accurate forecasts helped county officials decide on road closures and evacuation advisories; community officials advised residents to gather a seven-day supply of necessities and relocate their vehicles, minimizing disruption and potential damage.

Brazzell highlighted specific instances where the machine learning outputs were critical. For example, during the event that peaked around May 6, Streamflow A.I. accurately predicted the rise in stream height, allowing for timely road closures and advisories. These predictions were shared with county officials and were pivotal in their decision-making process.

This image shows the water levels after rainfall and predicts a moderate stream height in Pine Island Bayou. NASA

Brazzell shared that integrating SPoRT’s machine learning capabilities with their existing tools, such as flood risk mapping, proved invaluable. Although the machine learning outputs had been operational for almost two years after Hurricane Harvey, this season has provided their first significant applications in real-time scenarios due to persistent conditions of below-normal precipitation and ongoing drought.

He also mentioned the broader applications of Streamflow A.I., including its potential use in other sites beyond those currently being monitored. He expressed interest in expanding the use of machine learning stream height outputs to additional locations, citing the successful application in current sites as a compelling reason for broader implementation.

NASA SPoRT users’ experiences emphasize how crucial advanced prediction technologies are in hydrometeorology and emergency management operations. Based on Brazzell’s example, it is reasonable to say that the product’s ability to provide accurate, timely data greatly improves decision-making processes and ensures public safety. The partnership between NASA SPoRT and operational agencies like NOAA/NWS and county response teams demonstrates how research and operations can be seamlessly integrated into everyday practices, making a tangible difference in communities vulnerable to high-impact events.

As the Streamflow A.I. product continues to evolve and expand its applications, it holds significant promise for improving disaster preparedness and response efforts across various regions that experience different types of flooding events.

The Streamflow-AI product provides a 7-day river height or stage forecasts at select gauges across the south/eastern U.S. You can find the SPoRT training item on Streamflow-AI here.

Pinto is a research associate at the University of Alabama in Huntsville, specializing in communications and user engagement for NASA SPoRT.

Buckle Up: NASA-Funded Study Explores Turbulence in Molecular Clouds This image shows the distribution of density in a simulation of a turbulent molecular cloud. NASA/E. Scannapieco et al (2024)

On an airplane, motions of the air on both small and large scales contribute to turbulence, which may result in a bumpy flight. Turbulence on a much larger scale is important to how stars form in giant molecular clouds that permeate the Milky Way.

In a new NASA-funded study in the journal Science Advances, scientists created simulations to explore how turbulence interacts with the density of the cloud. Lumps, or pockets of density, are the places where new stars will be born. Our Sun, for example, formed 4.6 billion years ago in a lumpy portion of a cloud that collapsed.

“We know that the main process that determines when and how quickly stars are made is turbulence, because it gives rise to the structures that create stars,” said Evan Scannapieco, professor of astrophysics at Arizona State University and lead author of the study. “Our study uncovers how those structures are formed.”

Giant molecular clouds are full of random, turbulent motions, which are caused by gravity, stirring by the galactic arms and winds, jets, and explosions from young stars. This turbulence is so strong that it creates shocks that drive the density changes in the cloud.

The simulations used dots called tracer particles to traverse a molecular cloud and travel along with the material. As the particles travel, they record the density of the part of the cloud they encounter, building up a history of how pockets of density change over time. The researchers, who also included Liubin Pan from Sun Yat Sen University in China, Marcus Brüggen from the University of Hamburg in Germany, and Ed Buie II from Vassar College in Poughkeepsie, New York, simulated eight scenarios, each with a different set of realistic cloud properties.

The team found that the speeding up and slowing down of shocks plays an essential role in the path of the particles.  Shocks slow down as they go into high-density gas and speed up as they go into low-density gas. This is akin to how an ocean wave strengthens when it hits shallow water by the shore.   

When a particle hits a shock, the area around it becomes more dense. But because shocks slow down in dense regions, once lumps become dense enough, the turbulent motions can’t make them any denser.  These lumpiest high-density regions are where stars are most likely to form.

While other studies have explored molecular cloud density structures, this simulation allows scientists to see how those structures form over time. This informs scientists’ understanding of how and where stars are likely to be born.

“Now we can understand better why those structures look the way they do because we’re able to track their histories,” said Scannapieco.

By examining how they interact with shocks and pockets of density, scientists can better understand the structures in molecular clouds that lead to star formation. NASA/E. Scannapieco et al (2024)

NASA’s James Webb Space Telescope is exploring the structure of molecular clouds. It is also exploring the chemistry of molecular clouds, which depends on the history of the gas modeled in the simulations. New measurements like these will inform our understanding of star formation.

In the ever-evolving aerospace industry, collaboration and mentorship are vital for fostering innovation and growth. Recent achievements highlight the positive impact of Mentor-Protégé Agreements (MPA) facilitated by Jacobs Engineering Group, now known as Amentum Space Exploration Group. Two standout partnerships have demonstrated remarkable success and expansion, underscoring the value of such initiatives.

CODEplus and Amentum Space Exploration Group

The 24-Month MPA between CODEplus and Amentum Space Exploration Group has proven to be a game-changer. Recognized as the FY24 Marshall Space Flight Center (MSFC) Mentor-Protégé Agreement of the Year, this collaboration has significantly boosted CODEplus’s operations. Since the agreement’s inception on March 1, 2023, CODEplus has expanded its workforce to ten full-time employees and currently has two active job requisitions. This growth exemplifies the transformative potential of mentorship in nurturing small businesses within the aerospace sector.

KS Ware and Amentum Space Exploration Group / CH2M Hill

Another exemplary partnership involves KS Ware, which has benefitted from a 36-Month MPA with Amentum Space Exploration Group and CH2M Hill. This agreement has garnered accolades as both the FY23 NASA Agency Mentor-Protégé Agreement of the Year and the FY23 MSFC Mentor-Protégé Agreement of the Year. Through targeted business and technical counseling, KS Ware successfully launched a new drilling division in 2022 and expanded its offerings to include surveying services in 2023. The impact of this mentorship is evident, with a remarkable 30% growth rate reported for KS Ware.

These success stories highlight the critical role of Mentor-Protégé Agreements in empowering small businesses in the aerospace industry. By fostering collaboration and providing essential support, Amentum Space Exploration Group has not only strengthened its partnerships but also contributed to the broader growth and innovation landscape. As the aerospace sector continues to evolve, such initiatives will be essential in driving future success.

The tiny, potato-shaped moon Phobos, one of two Martian moons, cast a silhouette as it passed in front of the Sun, creating an eye in Mars’ sky.

From its perch on the western wall of Mars’ Jezero Crater, NASA’s Perseverance rover recently spied a “googly eye” peering down from space. The pupil in this celestial gaze is the Martian moon Phobos, and the iris is our Sun.

Captured by the rover’s Mastcam-Z on Sept. 30, the 1,285th Martian day of Perseverance’s mission, the event took place when the potato-shaped moon passed directly between the Sun and a point on the surface of Mars, obscuring a large part of the Sun’s disc. At the same time that Phobos appeared as a large black disc rapidly moving across the face of the Sun, its shadow, or antumbra, moved across the planet’s surface.

Astronomer Asaph Hall named the potato-shaped moon in 1877, after the god of fear and panic in Greek mythology; the word “phobia” comes from Phobos. (And the word for fear of potatoes, and perhaps potato-shaped moons, is potnonomicaphobia.) He named Mars’ other moon Deimos, after Phobos’ mythological twin brother.

Roughly 157 times smaller in diameter than Earth’s Moon, Phobos is only about 17 miles (27 kilometers) at its widest point. Deimos is even smaller.

Rapid Transit

Because Phobos’ orbit is almost perfectly in line with the Martian equator and relatively close to the planet’s surface, transits of the moon occur on most days of the Martian year. Due to its quick orbit (about 7.6 hours to do a full loop around Mars), a transit of Phobos usually lasts only 30 seconds or so.

This is not the first time that a NASA rover has witnessed Phobos blocking the Sun’s rays. Perseverance has captured several Phobos transits since landing at Mars’ Jezero Crater in February 2021. Curiosity captured a video in 2019. And Opportunity captured an image in 2004.

By comparing the various images, scientists can refine their understanding of the moon’s orbit to learn how it’s changing. Phobos is getting closer to Mars and is predicted to collide with it in about 50 million years.

More About Perseverance

Arizona State University leads the operations of the Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Niels Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets.

A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).

Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.

NASA to Launch Innovative Solar Coronagraph to Space Station

NASA’s Coronal Diagnostic Experiment (CODEX) is ready to launch to the International Space Station to reveal new details about the solar wind including its origin and its evolution.

Launching in November 2024 aboard SpaceX’s 31st commercial resupply services mission, CODEX will be robotically installed on the exterior of the space station. As a solar coronagraph, CODEX will block out the bright light from the Sun’s surface to better see details in the Sun’s outer atmosphere, or corona.

“The CODEX instrument is a new generation solar coronagraph,” said Jeffrey Newmark, principal investigator for the instrument and scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It has a dual use — it’s both a technology demonstration and will conduct science.”

This coronagraph is different from prior coronagraphs that NASA has used because it has special filters that can provide details of the temperature and speed of the solar wind. Typically, a solar coronagraph captures images of the density of the plasma flowing away from the Sun. By combining the temperature and speed of the solar wind with the traditional density measurement, CODEX can give scientists a fuller picture of the wind itself.

“This isn’t just a snapshot,” said Nicholeen Viall, co-investigator of CODEX and heliophysicist at NASA Goddard. “You’re going to get to see the evolution of structures in the solar wind, from when they form from the Sun’s corona until they flow outwards and become the solar wind.”

The CODEX instrument will give scientists more information to understand what heats the solar wind to around 1.8 million degrees Fahrenheit — around 175 times hotter than the Sun’s surface — and sends it streaming out from the Sun at almost a million miles per hour.

This launch is just the latest step in a long history for the instrument. In the early 2000s and in August 2017, NASA scientists ran ground-based experiments similar to CODEX during total solar eclipses. A coronagraph mimics what happens during a total solar eclipse, so this naturally occurring phenomena provided a good opportunity to test instruments that measure the temperature and speed of the solar wind.

In 2019, NASA scientists launched the Balloon-borne Investigation of Temperature and Speed of Electrons in the corona (BITSE) experiment. A balloon the size of a football field carried the CODEX prototype 22 miles above Earth’s surface, where the atmosphere is much thinner and the sky is dimmer than it is from the ground, enabling better observations. However, this region of Earth’s atmosphere is still brighter than outer space itself.

“We saw enough from BITSE to see that the technique worked, but not enough to achieve the long-term science objectives,” said Newmark.

Now, by installing CODEX on the space station, scientists will be able to view the Sun’s corona without fighting the brightness of Earth’s atmosphere. This is also a beneficial time for the instrument to launch because the Sun has reached its solar maximum phase, a period of high activity during its 11-year cycle.

“The types of solar wind that we get during solar maximum are different than some of the types of wind we get during solar minimum,” said Viall. “There are different coronal structures during this time that lead to different types of solar wind.”

This coronagraph will be looking at two types of solar wind. In one, the solar wind travels directly outward from our star, pulling the magnetic field from the Sun into the heliosphere, the bubble that surrounds our solar system. The other type of solar wind forms from magnetic field lines that are initially closed, like a loop, but then open up.

These closed field lines contain hot, dense plasma. When the loops open, this hot plasma gets propelled into the solar wind. While these “blobs” of plasma are present throughout all of the solar cycle, scientists expect their location to change because of the magnetic complexity of the corona during solar maximum. The CODEX instrument is designed to see how hot these blobs are for the first time.

The coronagraph will also build upon research from ongoing space missions, such as the joint ESA (European Space Agency) and NASA mission Solar Orbiter, which also carries a coronagraph, and NASA’s Parker Solar Probe. For example, CODEX will look at the solar wind much closer to the solar surface, while Parker Solar Probe samples it a little farther out. Launching in 2025, NASA’s Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission will make 3D observations of the Sun’s corona to learn how the mass and energy there become solar wind.

By comparing these findings, scientists can better understand how the solar wind is formed and how the solar wind changes as it travels farther from the Sun. This research advances our understanding of space weather, the conditions in space that may interact with Earth and spacecraft.

“Just like understanding hurricanes, you want to understand the atmosphere the storm is flowing through,” said Newmark. “CODEX’s observations will contribute to our understanding of the region that space weather travels through, helping improve predictions.”

The CODEX instrument is a collaboration between NASA’s Goddard Space Flight Center and the Korea Astronomy and Space Science Institute with additional contribution from Italy’s National Institute for Astrophysics.

Preparations for Next Moonwalk Simulations Underway (and Underwater) About 20,000 guests visited NASA’s tent at the Miramar Air Show in San Diego, California, Sept. 27-29, 2024. NASA

Lee esta historia en Español aquí.

In September, the three NASA centers in California came together to share aerospace innovations with thousands of guests at the Miramar Air Show in San Diego, California. Agency experts talked about the exciting work NASA does while exploring the secrets of the universe for the benefit of all.

Under a large tent near the airfield, guests perused exhibits from different centers and projects, like a model of the Innovator rover or the Alta-X drone, from Sept. 27 through 29. Agency employees from NASA’s Armstrong Flight Research Center in Edwards, California; Ames Research Center in Moffett Field, California; and Jet Propulsion Laboratory (JPL) in Southern California guided guests through tours and presentations and shared messages about NASA missions.

“The airshow is about the people just as much as it is about the aircraft and technology,” said Derek Abramson, chief engineer for the Subscale Flight Research Laboratory at NASA Armstrong. “I met many new people, worked with an amazing team, and developed a comradery with other NASA centers, talking about what we do here as a cohesive organization.”

Experts like flight controls engineer Felipe Valdez shared the NASA mission with air show guests, and explained the novelty of airborne instruments like the Alta-X drone at the Miramar Air Show in San Diego, California, Sept. 27-29, 2024.NASA

On Sept. 29, pilots from Armstrong joined the event to take photos with guests and answer questions from curious or enthusiastic patrons. One air show guest had a special moment with NASA pilot Jim Less.

“One of my favorite moments was connecting with a young man in his late teens who stopped by the exhibit tent numerous times, all in hopes of being able to meet Jim Less, our X-59 pilot,” said Kevin Rohrer, chief of Communications at NASA Armstrong. “It culminated with a great conversation with the two and Jim [Less] autographing a model of the X-59 aircraft the young man had been carrying around.”

“I look forward to this tradition continuing, if not at this venue, at some other event in California,” Rohrer continued. “We have a lot of minds hungry and passionate to learn more about all of NASA missions.”

The Miramar Air Show is an annual event that happens at the Miramar Air Base in San Diego, California.
