    What is AI?

    Artificial intelligence, or AI, is a type of technology that helps machines and computers have “thinking” abilities similar to humans. Devices using AI can learn words and concepts, recognize objects, see patterns, or make predictions. They can also be taught how to work autonomously. AI is often used to help people understand and solve problems more quickly than they could on their own.

    AI includes:

    • Machine learning: This type of AI looks at large amounts of data and learns how to make fast and accurate predictions based on that data. 
    • Deep learning: This type helps computers operate much like the human brain. It uses several layers of “thought” to recognize patterns and learn new information. Deep learning is a type of machine learning. 
    • Generative AI: A human can use generative AI to create text, videos, images, and more. It is based on deep learning.

    How is NASA using AI?

    NASA has found uses for AI in many of its missions and programs.

    For missions to the Moon, AI can use satellite imagery to create detailed 3D maps of dark craters. This data could help scientists plan missions, spot hazards, and even identify where future crews might find water ice. On Mars, the Perseverance rover uses AI to drive itself autonomously. It takes pictures of the ground, sees obstacles, and chooses the safest path.

    AI also helps NASA search for planets outside our solar system. For example, AI has helped citizen scientists find over 10,000 pairs of binary stars. These pairs orbit each other and block each other’s light. This information could help scientists search for new planets and learn more about how stars form.

    Words to Know

    Autonomous: acting or operating independently, without external control. An autonomous technology can perform duties without human intervention.

    Citizen scientist: a member of the public, often a volunteer, who collects data that can be used by scientists. When members of the public participate in research in this way, it’s called citizen science.

    ———————————————————————————————

    NASA also uses AI to support its work on Earth.  The agency uses AI to aid disaster relief efforts during and after natural disasters like hurricanes or wildfires. For example, AI can count tarps on roofs in satellite images to measure damage after a storm. NASA is also supporting flight controllers and pilots by using AI to plan better flight routes, making air travel safer and more efficient. 

    AI is helping NASA explore space, protect people, and make amazing discoveries!

    The Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope captured glowing cosmic dust heated by very young massive stars in unprecedented detail in this image of the Sagittarius B2 (Sgr B2) molecular cloud released on Sept. 24, 2025.

    Sgr B2 is the most massive, and active star-forming region in our galaxy, located only a few hundred light years from our central supermassive black hole. While Sgr B2 has only 10% of the galactic center’s gas, it produces 50% of its stars. Astronomers want to figure out why it is so much more active than the rest of the galactic center.

    MIRI has both a camera and a spectrograph that sees light in the mid-infrared region of the electromagnetic spectrum. MIRI’s view reveals colorful stars punctuated occasionally by bright clouds of gas and dust. Further research into these stars will reveal details of their masses and ages, which will help astronomers better understand the process of star formation in this dense, active galactic center region.

  • Mark Elder: Building the Future of Spacewalking for Artemis and Beyond 

    For more than 25 years, Mark Elder has helped make human spaceflight safe and possible. As the International Space Station EVA hardware manager in the Extravehicular Activity (EVA) Office within the EVA and Human Surface Mobility Program, he leads the team responsible for the spacesuits, tools, and logistics that keep astronauts protected during spacewalks—and ensures NASA is ready for the next era of Artemis exploration.

    His team is programmatically responsible for the Extravehicular Mobility Unit, or EMU, spacesuit. That means every bolt, bearing, and battery astronauts rely on outside the International Space Station ultimately falls under their watch. He also oversees the EVA Space Operations Contract, which provides engineering and technical support to keep spacesuit systems flight ready. 

    Elder’s work directly supports every EVA, or spacewalk, conducted at the station. His team coordinates with astronauts, engineers, and the Mission Control Center in Houston to make sure the suits and tools operate reliably in the most unforgiving environment imaginable. Their work helps ensure every EVA is conducted safely and successfully. 

    Elder’s passion for NASA began at an early age. 

    “When I was little, my parents gave me a book called ‘The Astronauts,’” he said. “It had drawings of a reusable spacecraft—the space shuttle—and I fell in love with it. From then on, I told everyone I was going to work at NASA.” 

    That dream took off at age 16, when he attended Space Academy in Huntsville, Alabama. “That cemented my dream of someday working at NASA, and it taught me a little bit more about the different roles within the agency,” he said. 

    While attending Case Western Reserve University as a mechanical engineering student, he learned about a new NASA program that allowed college students to design and build an experiment and then come to Johnson Space Center for a week to fly with their experiment on the Boeing KC-135 Stratotanker. “I jumped on the chance to be part of the team,” he said. “The experience further cemented my dream of working at NASA one day—Johnson in particular.” 

    After graduation, Elder worked with Pratt & Whitney on jet engines. While the experience was invaluable, he knew his heart belonged in human spaceflight. “I learned that one of Pratt’s fellow companies under the United Technologies umbrella was Hamilton Sundstrand, which was the prime contractor for the spacesuit,” he said. “I jumped at the chance to transfer, and my career at NASA finally began.” 

    Elder spent his first three years at Johnson performing tool-to-tool fit checks on spacewalking equipment, giving him hands-on experience with nearly every tool that he would eventually become responsible for as a hardware manager. 

    Mark Elder stands in front of the Space Shuttle Atlantis before the STS-117 launch on June 8, 2007.

    His early years coincided with the shuttle return-to-flight era, when he worked on reinforced carbon-carbon panel repairs and thermal protection systems. Those experiences built his technical foundation and prepared him for the leadership roles to come. 

    Over time, Elder took on increasingly complex assignments, eventually leading the team that developed the EVA Long Life Battery—the first human-rated lithium battery used in space. His team created a rigorous test plan to certify the battery for human spaceflight at a time when lithium batteries were under scrutiny for safety concerns. 

    “Finally signing the certification paperwork was satisfying, but watching an EVA powered by the batteries provided a great sense of pride,” he said. 

    This innovation set the stage for future generations of even safer, higher-capacity batteries that power today’s spacewalking operations and will eventually support lunar surface activities. 

    Looking back, Elder said some of his greatest lessons came from learning how to lead with purpose. “The great thing about NASA is the highly motivated and dedicated workforce,” he said. “When I first became a team lead, I thought success meant making quick decisions and moving fast. I learned that leadership is really about listening. Strong teams are built on trust and open communication.” 

    Another defining lesson, he said, has been learning to assume positive intent. “In a place like NASA, everyone is deeply passionate about what they do,” he said. “It’s easy to misinterpret a disagreement as opposition, but when you remember that everyone is working toward the same goal, the conversation changes. You focus on solving problems, not winning arguments.” 

    That mindset has guided Elder through some of NASA’s most complex programs and helped him build lasting partnerships across the agency.

    Today, Elder’s work extends beyond the orbiting laboratory. As NASA prepares for Artemis missions to the Moon, his team’s experience maintaining and improving the EMU informs the design of next-generation exploration suits. 

    “The foundation we’ve built on the space station is critical for the future,” he said. “Every tool we’ve refined, every system we’ve upgraded—it all feeds into how we’ll operate on the lunar surface and eventually on Mars.” 

    Elder believes that the key to future success lies in perseverance. He advises the next generation to never stop dreaming. “My path wasn’t direct, and it would have been easy for me to give up,” he said. “But dreams have a way of guiding you if you don’t let go of them.” 

    When he’s not supporting those missions, Elder’s creativity takes shape in his workshop. “In my spare time, I love woodworking,” he said. “Building something useful from a pile of rough-sawn boards helps calm me and gives me a great sense of accomplishment. I love being able to build furniture for my family,” he added, after recently finishing a desk for his youngest son. 

    The same patience and precision he brings to woodworking defines his approach to exploration—steady progress, careful craftmanship, and attention to detail. “As NASA goes to the Moon and Mars, there will be challenges,” Elder said. “As long as we keep dreaming, we will see the next generation walking on the Moon and heading to Mars.”
