In-space manufacturing and assembly are vital to NASA’s long-term exploration goals, especially for the Moon and Mars missions. Deploying welding technology in space enables the assembly and repair of structures, reducing logistical burdens and supply needs from Earth. The unique challenges and extreme conditions of space–high thermal variations, microgravity, and vacuum–require advanced welding techniques and computational tools to ensure reliability, repeatability, safety, and structural integrity in one-shot weld scenarios. For the first time, this project investigates these challenges by focusing on three key factors: (1) Very low temperatures in space degrade the weldability of high thermal conductivity materials, like aluminum alloys, making it harder to achieve strong, defect-free welds. (2) The extreme vacuum in space lowers the boiling points of alloying elements, altering the keyhole geometry during welding. This selective vaporization changes the weld’s final chemical composition, affecting its microstructure and properties. (3) Microgravity nearly eliminates buoyancy-driven flow of liquid metal inside the molten pool, preventing gas bubbles from escaping, which leads to porosity and defects in the welds. By examining these critical factors using multi-scale multi-physics models integrated with physics-informed machine learning, and forward/inverse uncertainty quantification techniques, this project provides the first-ever real-time digital twin platform to evaluate welding processes under extreme space/lunar conditions. The models are validated through Earth-based experiments, parabolic flight tests, and publicly available data from different databases and agencies worldwide. Moreover, the established models will facilitate extendibility to support in-situ resource utilization on the Moon, including construction and repair using locally sourced materials like regolith. The established fundamental scientific knowledge will minimize trial-and-error, enable high-quality one-shot welds in space, and reduce the need for reworks, significantly reducing the costs and time needed for space missions.

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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA project manager Patricia Ortiz stands in front of the X-1E research aircraft at NASA’s Armstrong Flight Research Center in Edwards, California.NASA Lee esta historia en Español aquí.
Patricia Ortiz is proud to be a first-generation Salvadoran American. Her mother, born and raised in El Salvador, came to the United States for a better opportunity despite not knowing anyone or the English language.
As a project manager for Space Projects and Partnerships at NASA’s Armstrong Flight Research Center in Edwards, California, Ortiz manages various space and aeronautics projects for new technologies that begin from the early stages to the execution. This involves meeting with partners, working with leadership and managing the project for performance and mission success.
While reflecting on her journey to NASA, Ortiz honors her mother for her resiliency and the impact she had on her. “My mom faced a lot of hardship in coming to this country, but she came to this country so that I could do this.” This brave decision to move to an unfamiliar place was what opened the door for Ortiz to eventually work for NASA.
Ortiz enjoys staying connected to her Salvadoran roots and one way she does this is through food. Her favorite dish: the pupusa. “My mom makes the best pupusas with chicharrón [pork], cheese, and curtido [cabbage slaw]. It’s so delicious!”

“It’s 2 a.m. in the morning on a Sunday. You have your headset in your hand. You’re about to walk into Mission Control. And you understand — in the darkness, the crickets chirping, the lights shining on the building — you understand where you’re going and what you’re a part of.
“This is the building where we heard astronauts say, ‘Houston, we’ve had a problem.’ Where we heard, ‘the Eagle has landed.’ And the people on the ground supporting those historic missions were in this building — and now I get to be a part of that.
“There is just this undying sense of wonder every time I walk into this building. Not to say that there isn’t an undying sense of wonder at many of the other buildings at Johnson [Space Center]. But with this building in particular, having that ownership and that responsibility as I walk in — that will never go away. It’s wonderful.”
—Gary Jordan, Public Affairs Manager, NASA’s Johnson Space Center
