Machines and engines are all around us. They power everything from cars and boats to airplanes and even rockets. Mechanics are experts who know how machinery works, especially engines, and how to fix them.
When you think of a mechanic, you might picture someone working on cars. But mechanics can be experts on all kinds of machinery.
At NASA, mechanics perform a variety of functions. For example, aerospace mechanics maintain the airplanes studied at NASA’s Armstrong Flight Research Center in Edwards, California. These might include research planes studying the environment or experimental aircraft testing new wing designs.
At NASA’s Kennedy Space Center in Florida, mechanics keep machines like the crawler-transporters in top working condition. These massive machines carry rockets from the building where they are assembled to the launch pad.
Mechanics at the agency’s Michoud Assembly Facility in New Orleans ensure the fleet of barges used to carry powerful rocket sections are maintained and ready to use. These large ships have been used for decades to carry rocket parts to various NASA centers for testing and launches.
There are many options that provide the training needed to get started as a mechanic. Different types of mechanics require different types of training and certifications. Here are a few examples.
Automotive mechanic: Automotive mechanics are experts at the interconnected systems in cars and trucks. After getting a high school diploma or GED, seek out trade or technical schools that have mechanic training programs. These provide hands-on experience. Further training may be required to work on specific types of automobiles. Certifications can help you advance specific skills and demonstrate proficiency.
Heavy equipment mechanic: The path to a career as a heavy equipment mechanic often begins with a two-year degree. Look for a program at your local community college or technical school. Opportunities to begin working right after high school are also available. You may start by doing basic tasks or by being paired with a senior mechanic to build skills. Most heavy equipment mechanics go through three to four years of hands-on training before taking certification and licensing tests.
Aircraft mechanic: Maintaining and repairing aircraft requires a special skillset. Community colleges and technical schools offer programs approved by the Federal Aviation Administration. These programs can fast-track your route to a career. They provide hands-on experience and help you prepare for tests needed to receive your certifications.
For many mechanic roles, military service is also a way to get training and certifications.
In high school, take courses in math, science, and industrial technology. Check out any career and technical education programs your school might offer. Read repair manuals and look for online tutorials to figure out the basics of how machines work.
You can also gain useful experience through part-time work. Look for jobs or shadowing opportunities at your local repair shop.
Begin researching training programs, community colleges, and apprenticeship opportunities. Compare options to see which pathway seems right for you. This will help you understand program requirements and ensure you’re ready to take the next step.
Mechanics must be good problem solvers. Troubleshooting repairs on complex machinery requires logical thinking and patience. Being detail-oriented is critical to make sure measurements are correct and safety specifications are met.
Keeping up with the latest technology is important, too. Mechanics use computer equipment and electronic sensors to run diagnostics. And machinery technology can evolve rapidly with new advancements like electric vehicles and drones. Take initiative and stay curious.

Photographers at NASA’s Johnson Space Center in Houston have documented some of the most defining moments in human spaceflight.
From astronaut training and engineering tests to mission control operations and milestone celebrations, their images preserve the history of exploration while capturing the people and teams behind the missions shaping the next era.
Meet the photographers behind the lens and explore the stories behind the images that have helped tell NASA’s story.

Robert Markowitz
NASA Photographer
For more than three decades, NASA photographer Robert Markowitz has documented the people and milestones that have shaped NASA’s human spaceflight program. His career has spanned the space shuttle program, 25 years of continuous human presence aboard the International Space Station, and Artemis II.
“My favorite part of this job has always come down to the range of assignments we take on and the people I get to work with every day,” Markowitz said.
One of Markowitz’s early career highlights came during the filming of “Apollo 13,” when he served as the behind-the-scenes still photographer for nearly every KC-135 zero-gravity flight. “Looking back as a 25-year-old photographer at Johnson, I don’t think I fully appreciated how unique an opportunity it was to be there documenting those moments,” he said.
Markowitz says the job has challenged him to grow as both a photographer and a communicator. Whether photographing dozens of individual portraits in a day or coordinating a 300-person group photo, each assignment has strengthened his ability to adapt, collaborate, and connect with people.
“This work has shaped not just my career, but my life,” he said. “Being part of a team that captures and preserves the story of human spaceflight continues to be one of the great honors of my time at Johnson.”

Bill Stafford
NASA Photographer
NASA photographer Bill Stafford’s path to Johnson began during his senior year of college, when a friend who was completing a photography internship at the center told him about an opening on the photography team. With a longtime interest in science and technology, Stafford saw the opportunity to combine those interests with photography in an extraordinary environment.
Stafford approaches each assignment as a technical challenge and a storytelling opportunity. Whether working around constraints in lighting, timing, or access, he uses composition, visual psychology, and an understanding of how a viewer’s eye moves through an image to shape the final photograph.
“My favorite part of the job is the problem-solving that comes with it,” Stafford said.
Working at Johnson has sharpened those instincts as he photographs spacecraft, hardware, astronauts, and the people behind NASA’s human spaceflight missions.
“So many of the subjects I photograph carry weight and history that I want the image to reflect,” he said.

James Blair
NASA Photographer
From newspapers across the country to working as a photographer and photo editor for a publication in Ecuador, NASA photographer James Blair began his career in photojournalism. Photography has taken him around the world, a path that has continued at Johnson with assignments ranging from astronaut training to geology field training in Iceland.
“Since I was very young, I have always been fascinated by spaceflight and the technology it takes to reach beyond Earth’s atmosphere,” Blair said.
At Johnson, Blair combines that fascination with his photojournalism background to document the people and technology shaping NASA’s next era of exploration.
“I enjoy documenting the new hardware that is being developed to return us to the Moon,” he said. “From spacesuits to rovers and potential lunar habitats, I get to show the world what NASA has in store for the future of human spaceflight.”

Helen Arase Vargas
NASA Photographer
NASA photographer Helen Arase Vargas began her career in photojournalism and reporting in Southern California before joining Boeing’s scientific photography team in El Segundo. Her experience photographing aerospace sparked an unexpected interest that eventually led her to Johnson.
“The best part of the job is my coworkers; cheesy, but there is so much to learn from everyone,” Arase Vargas said. “Our core team has so much knowledge. They are all quick to offer help and are great humans.”
Arase Vargas says much of the work at Johnson reflects the journalism ethics she learned early in her career and fulfills her desire to serve the public interest.
The range and volume of assignments also helped her become more comfortable working in different environments while continuing to develop her craft.
For Arase Vargas, documenting the Artemis II crew’s return to Ellington Field in Houston came with a heightened sense of responsibility.
“The world is watching, and all that imagery must be rushed out by the lab,” she said. “Your photo could be the one that ends up on every news site, and you don’t want to miss capturing the joy and celebration the moment deserves.”

Luna Posadas Nava
NASA Photographer
NASA photographer Luna Posadas Nava’s path to Johnson spans emerging technology, optics and imaging systems, and photographing artists across the East Coast. Her work grew from a desire to visualize and expand the boundaries of what is possible.
Joining Johnson shortly before the launch of NASA’s Artemis II mission, one of Posadas Nava’s first experiences was helping bring Moon Joy to the world. She documented the Science Evaluation Room, where scientists worked together to conduct real-time lunar science observations during the mission’s lunar flyby.
Posadas Nava said it was inspiring to witness the team at work and especially meaningful to see so many women contributing to the mission’s science.
Seeing the response from women in her own life and online reinforced for Posadas Nava the power of representation through photography.
“When we see ourselves in stories, we imagine new futures,” she said. “I hope my work helps more people see themselves in the story of exploration, because what we see shapes what we believe is possible.”

David DeHoyos
NASA Photographer
Growing up in Houston during the Apollo era, NASA photographer David DeHoyos knew from an early age that he wanted to be part of the space industry. His interest in photography began with his mother’s Kodak Instamatic camera and continued through school and a decade working in photo labs. In 1991, that path brought him to Johnson’s photo lab and eventually behind the camera as a NASA photographer.
After more than three decades at Johnson, DeHoyos says connecting with people remains one of his favorite parts of the job. He enjoys learning about the people he photographs, sharing what he has learned about Johnson with visitors and new employees, and encouraging the next generation.
“I keep an assortment of NASA goodies in my camera bag, and the ultimate joy I get is giving a pin or sticker to a child and seeing their little faces just light up,” DeHoyos said. “It just warms my heart to encourage a youngster to work hard and pursue their dreams because that’s how I got here.”
For DeHoyos, photography is also about preserving moments that can take on greater meaning over time.
“I love the process of figuring out technical details to create an image that will make someone say, ‘Wow, cool shot, how did you do that?’” he said.

Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: Whatdunit? What disappeared while crossing a partially eclipsed Sun? Let’s present the evidence. The 24 frames-per-second video was taken in Spain (40°34’30.3″N 1°12’28.8″W) at 20:28 local time on August 12, 2026. The Perseids meteor shower was at its peak during this time. Is this a meteor? Meteor showers trace back to a region of the sky called a radiant point that corresponds to where the Earth is crossing a comet’s path. The object’s path might trace back to the Perseids’ radiant point in the Perseus constellation. The object trails a smaller angle on the sky than the 0.5 degree Sun and Moon, which is smaller than expected for a meteor. Its brightness does not extend much past the Sun, but a meteor burning up in the sky would not need sunlight to be seen. Perhaps the sunlight is reflecting off of the object? After cross-referencing the location, time, and point in the sky with a flight database, the culprit is found to be an airplane contrail!
