Tessa Keating is a public affairs specialist in the Office of Communications at NASA’s Stennis Space Center. Keating plans onsite logistics, serves as a protocol officer, and coordinates the Space Flight Awareness Program for NASA Stennis and the NASA Shared Services Center.NASA/Danny Nowlin Every task at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, is not simply work for Tessa Keating – it is a meaningful step toward a part of something great.
“It has been a dream career. I count it an honor to share the NASA story and humbled to know our team witnesses a part of history,” said Keating, a NASA public affairs specialist in the NASA Stennis Office of Communications. “Every day is an opportunity to contribute to the NASA legacy that will last beyond today. “
Keating plans onsite logistics, serves as a protocol officer, and coordinates the Space Flight Awareness Program for NASA Stennis and the NASA Shared Services Center. In fact, she organized much of the recent Space Flight Awareness Silver Snoopy Award ceremony at NASA Stennis in August, except for one part. As the ceremony finished, NASA Stennis Director John Bailey said one more award was to be given.
No one was more surprised than the logistics coordinator herself when Keating’s family joined her on stage. The 21-year NASA Stennis employee was honored for her outstanding contributions in sharing the NASA story of exploring the secrets of the universe for the benefit of all with a diverse audience and for equipping everyone with a broader knowledge and appreciation of the center’s vital role within NASA.
“I am not sure I will ever be able to top that in my NASA career,” Keating said.
It became a full-circle moment that she described as a great honor. The Silver Snoopy is the astronauts’ personal award and is presented to less than 1 percent of the total NASA workforce. Reid Wiseman, a NASA astronaut and commander for the upcoming Artemis II mission around the Moon, presented the award to Keating, along with a lapel pin flown aboard NASA’s Artemis I mission.
As NASA returns to the Moon for scientific discovery, economic benefits, and inspiration for the Artemis Generation, Keating says it will be extra-special watching Wiseman and the Artemis II crew lay the groundwork for future milestones.
Keating helped lay the groundwork ahead of the successful Artemis I mission. She served as lead logistics for onsite guest operations in 2021 when NASA conducted the most powerful propulsion test in more than 40 years at NASA Stennis. A full-duration hot fire of the first SLS (Space Launch System) core stage and its four RS-25 engines culminated a year-long series of integrated tests. Keating coordinated the viewing of the hot fire for some 200 agency leaders and guests, despite restricted settings due to COVID-19.
“It was truly a highlight. I had grown up hearing my parents and grandparents talk about engines that were tested during the Apollo era, and I had never experienced something of that magnitude,” Keating said. “I was able to live it, feel it, and watch the next part of NASA history onsite.”
For Keating, the groundwork for a NASA career came following graduation with a bachelor’s degree in Journalism from William Carey University and a master’s degree in Communications from The University of Southern Mississippi, both schools in Hattiesburg, Mississippi. Having grown up in Pearl River County, Mississippi, for most of her life, she knew about NASA Stennis. However, she did not think she could ever work at the center because her strengths were in areas beyond math and science.
Following some additional exploration and conversations with influential people in her life, Keating discovered she, in fact, could be a part of something great at NASA Stennis.
“The possibilities are endless at NASA when you allow yourself to put your best foot forward and research the many opportunities that are available. There is always room for various types of studies,” Keating said. “I credit where I am in my career to God and to the people who have helped to guide my path. I will be forever grateful.”

Citizen science projects enabled by data from the WISE and NEOWISE missions have given hundreds of thousands around the world the opportunity to make new discoveries. The projects can be done by anyone with a laptop and internet access and are available in fifteen languages. No U.S. citizenship required. NASA’s NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) spacecraft re-entered and burned up in Earth’s atmosphere on Friday night, as expected. Launched in 2009 as the WISE mission, the spacecraft has been mapping the entire sky at infrared wavelengths over and over for nearly fifteen years. During that time, more than one hundred thousand amateur scientists have used these data in citizen science projects like the Milky Way Project, Disk Detective, Backyard Worlds: Planet 9, Backyard Worlds: Cool Neighbors, and Exoasteroids.
This citizen science work has led to more than 55 scientific publications. Highlights include:
The discovery of Yellowballs, a kind of compact star-forming region. The discovery of Peter Pan Disks, long lived accretion disks around low-mass stars. The discovery of the first extreme T subdwarfs. The likely discovery of an aurora on a brown dwarf. Measurement of the field substellar mass function down to effective temperature ~400 K. The discovery of the oldest known white dwarf with a disk. Detection of a possible collision between planets. The discovery of the lowest-mass hypervelocity star. Although the spacecraft is no longer in orbit, there is plenty of work to do. The WISE/NEOWISE data contain trillions of detections of astronomical sources – enough to keep projects like Disk Detective, Backyard Worlds: Planet 9, Backyard Worlds: Cool Neighbors, and Exoasteroids busy making new discoveries for years to come. Join one of these projects today to help unravel the mysteries of the infrared universe!

Born and raised in Mexico City, Carlos Fontanot has dedicated 34 years to NASA. He supports the International Space Station Mission Integration and Operations Office, ensuring that high-quality imagery enhances mission objectives and operations.
Fontanot is known for conceiving and leading the High Definition Earth Viewing (HDEV) project, which has brought stunning live visuals of Earth to millions around the globe. As he approaches his well-deserved retirement, we are excited to spotlight Fontanot’s remarkable career, celebrating his contributions to NASA and the lasting impact he has made on the agency’s mission to share the wonders of space.
Carlos Fontanot (left) receives the Great Minds in STEM Lifetime Achievement Award from Joel Montelbano, NASA at the Hispanic Engineer National Achievement Award Conference. What does your position entail?
Integrate all aspects of station imagery, from initial requirements to acquisition, processing, cataloging, archiving, and distribution of station imagery to multiple stakeholders, our clients.
How would you describe your job to family or friends who may not be as familiar with NASA?
I manage an array of television and digital still imagery cameras on the International Space Station. Each day we receive eight channels of high definition (HD) video and thousands of digital images that allow the ground team to see what the crew is doing in their daily lives and as part of scientific activities. In today’s age of social media and high-quality imagery, having these images is crucial for effectively conveying the station narrative.
I also chair the International Space Station’s Multilateral Imagery Working Group. Our team captures and processes the video and still images on a large server, where they are cataloged, archived, and distributed to our clients. Additionally, we are responsible for the photo and TV hardware aboard the space station and provide training to astronauts on how to use this equipment.
Carlos Fontanot with Liam Kennedy at the International Space Station Research and Development Conference. How do you feel the imagery and public affairs teams contribute to the overall mission of NASA?
Imagery is critical for communication in today’s visual environment. If people can’t see it, they won’t believe it! Effective communication through multimedia and pointed messaging is essential for securing continued support for NASA missions from both Congress and the public.
What was your path to NASA?
I was always interested in photography and film, so I studied radio, TV, and film in college. My first job after graduation was with a local TV station, and I also managed a media center for a multinational company. Then, I joined Johnson Space Center’s television and film division, where I managed space shuttle and institutional imagery.
Once at Johnson, I worked in the Office of Public Affairs as the audiovisual manager and served for two years as the public affairs officer in Moscow at the start of the International Space Station Program, including the launch of the first station crew.
What advice would you give to young individuals aspiring to work in the space industry or at NASA?
NASA is not just about astronauts, flight controllers, and engineers—there are countless disciplines and job opportunities here. Take imagery, for example: in today’s digital age, having the highest resolution imagery of our incredible orbiting laboratory environment and our home planet is essential.
For those aspiring to join the NASA team, I encourage you be open-minded and a team player. We need well-educated and talented individuals from diverse backgrounds across all disciplines to help us achieve our goals and explore the wonders of space.
Is there a space figure you’ve looked up to?
The space figure I will always remember and look up to is John Glenn. I had the fortune and privilege to meet him during his training. He was an extraordinary human being with incredibly high goals throughout his career.
I was assigned to escort John Glenn and the STS-95 crew on a two-week official visit to several European countries. John was by far the most inspiring and dedicated crew member that I’d ever met. He was always ready and willing to engage with dignitaries, politicians, leaders, journalists, and the public to share the NASA story and promote future programs to gain support from various governments and the public.
What do you love sharing about the International Space Station to general audiences?
I love sharing the wonders of life in space, especially the unique and breathtaking views of our planet Earth that can only be appreciated from space. I like to tell audiences about the observations and inspiration our astronauts share upon returning from their missions. I emphasize our thin and fragile atmosphere that sustains life as we know it, the beauty of Earth’s deserts, mountains, jungles, and oceans, and most importantly, the absence of borders. There’s always a profound realization that we are all human and that Earth belongs to all of us.
How has the technology for capturing images and video in space evolved over the years?
There was no digital imagery when I started my professional career. Photographs were taken on film that had to be processed in a dark room using chemicals to produce images. Video was recorded on two-inch magnetic tape at low resolution. We even flew film on our spacecraft that had to be brought back and processed on the ground.
Today, in the digital world, images can be streamed directly from our spacecraft and almost instantaneously shared with the entire globe. The evolution of technology has truly transformed how we capture and share the wonders of space!
Carlos Fontanot (left) sets up a NASA imagery exhibit in the Houston Downtown Tunnel System. What are some of the key projects you’ve worked on during your time at NASA? What have been your favorites?
During my time at NASA, I co-led the High Definition Earth Viewing (HDEV) project, which deployed four Earth-viewing cameras on the International Space Station, reaching over 318 million viewers globally. I also contributed to designing Johnson’s new PAO studio, collaborated on upgrading the space station’s downlink system from four standard-definition to eight high-definition channels, and advanced television technology, including the first HD and later UHD live downlinks from the station. These projects have allowed me to enhance NASA’s capacity for sharing space imagery with the world.
What are your plans for retirement, and how do you hope to stay connected to the space community?
I plan to travel across the U.S. in a travel trailer with my wife and dog and enjoying my hobbies I will now have time for, such as photography and spending quality time with my family.
Carlos and Pat Fontanot at the Grand Canyon South Rim in Arizona. How do you believe NASA’s imagery can continue to inspire future generations?
Astronaut John Young would come to the photo lab after every shuttle mission to review the film shot onboard. He would say, “A picture is worth a thousand words.” What can inspire more than a breathtaking image of a sunset captured from space or the aurora borealis over the polar regions?
What legacy do you hope to leave behind after your time at NASA?
I hope to leave behind a legacy of passion and dedication to acquiring and making pristine, high-resolution imagery from space available for the public to enjoy.
If you could have dinner with any astronaut, past or present, who would it be?
I would choose John Young. He flew during both the Apollo and shuttle eras, was an imagery expert, and had a deep understanding of the space station.

X-ray: NASA/CXC/SAO/J. Drake et al, IR: NASA/JPL-Caltech/Spitzer; Image Processing: NASA/CXC/SAO/N. Wolk 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.
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 this 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 5 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 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 a composite image of the Cygnus OB2 star cluster, which resembles a night sky blanketed in orange, purple, and grey clouds.
The center of the square image is dominated by purple haze. This haze represents diffuse X-ray emissions, and young stars, detected by the Chandra X-ray observatory. Surrounding the purple haze is a mottled, streaky, brick orange cloud. Another cloud resembling a tendril of grey smoke stretches from our lower left to the center of the image. These clouds represent relatively cool dust and gas observed by the Spitzer Space Telescope.
Although the interwoven clouds cover most of the image, the thousands of stars within the cluster shine through. The lower-mass stars present as tiny specks of light. The massive stars gleam, some with long refraction spikes.
