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.

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.”

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.

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.”

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.”

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.

APOD: 2026 August 19 – The Case of the Mysterious Maybe Meteor

2026-08-19 04:05

APOD

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.

The Case of the Mysterious Maybe Meteor

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!

NASA’s LRO Images Falcon 9 Crater on Moon, Learns New Details

NASA’s LRO Images Falcon 9 Crater on Moon, Learns New Details

Two-frame animation showing a new crater, with ejecta rays extending outward, appearing on the Moon.
This is an animated before-and-after view of the crater formed after a Falcon 9 upper stage struck the Moon’s surface on Aug. 5, 2026. These images were taken between Aug. 11 and 12 by the Narrow-Angle Camera on NASA’s Lunar Reconnaissance Orbiter. These images are enlarged three times from the original, with north facing up, and they cover an area about a quarter of a mile wide.

Between Aug. 11 and 12, NASA’s Lunar Reconnaissance Orbiter (LRO) captured a series of images of a new crater on the Moon. The crater formed on Aug. 5, when a SpaceX Falcon 9 upper stage impacted the surface following its January 2025 launch of the Firefly Blue Ghost 1 mission.

To capture imagery of the impact, engineers tilted the spacecraft so its cameras would point toward the crater each time LRO passed about 60 miles above the Moon, traveling 1 mile per second. The orbiter circles the Moon from pole to pole every two hours, while the Moon slowly rotates underneath it. To photograph a specific spot, the spacecraft must wait until that location turns into view, which took six days in this case.

Getting the pointing right was only half the challenge; timing had to be accurate as well. If the camera snapped even 10 seconds too early or too late, the target would drift off-center by 10 miles.

Because of the variety of viewing angles, scientists could see the crater under multiple lighting conditions that revealed unique features. In images where the crater rim stood out, scientists measured its 60‑foot width. Scientists also determined the crater is less than 10 feet deep based on the length of its shadow.

To capture these details, LRO used its Narrow-Angle Camera, which can spot features as small as 3 feet wide.

Four black-and-white views of the same cratered lunar surface, each taken from a different angle. A small, bright boulder or mound near the center casts shadows that change direction across the images. The panels are labeled 105°, 90°, 53°, and 37°.
Collected between Aug. 11 and 12 by NASA’s Lunar Reconnaissance Orbiter, six days after a Falcon 9 upper-stage booster impacted the Moon, these images were taken from different viewing angles, bringing out different features. The darker area that fans around the crater in the upper-left image is rougher than the surroundings, as this surface material has been altered over a long time by solar wind, galactic cosmic rays, and micrometeorite impacts. The brighter rays and splotch above the crater in the lower-right image is fresher material that was excavated from deeper below the surface. The pictures are arranged in the order they were taken, starting at the top left and moving toward the bottom right, with the lighting angle from the Sun gradually changing from one image to the next. Each image is enlarged two times and shows an area of the Moon about 1,000 feet wide.

The images above show bright and dark rays stretching out from the crater. The darker streaks are made of surface dust and rocks altered over a long time by solar wind, galactic cosmic rays, and micrometeorite impacts. This weathered material was excavated by the collision from 1.5 feet into the lunar surface. The brighter streaks near the crater rim are made of fresh material excavated from deeper underground.

This image from NASA’s Lunar Reconnaissance Orbiter shows two oval regions where the Falcon 9 upper stage was likely to impact the Moon, based on calculations by engineers with NASA’s Center for Near Earth Object Studies. Both ellipses are 2.1 miles long and 0.4 miles wide. Both predictions use the same booster-trajectory calculations, but only the blue ellipse takes into account the lunar terrain (vs. a smooth sphere). The red and blue dots show predicted impact locations, whereas the cyan dot shows the actual impact site.
NASA/JPL-Caltech

Finding the impact site took global coordination among experts and hobbyists. Independent astronomers first identified the rocket’s trajectory using publicly available data. NASA’s Center for Near Earth Object Studies, which tracks natural objects that could pose hazards to Earth for the agency’s Planetary Defense program, used this opportunity to test and validate tools and techniques for predicting impacts.

Based at NASA’s Jet Propulsion Laboratory in Southern California, the center incrementally refined the trajectory until identifying the location of impact, which it provided to the Republic of Korea for their Korea Pathfinder Lunar Orbiter (Danuri) team. The team used the high-resolution LUTI camera on Danuri a few hours later to image the crater, finding the prediction was accurate to about 0.6 miles. 

After capturing images of the crater, the Danuri mission sent coordinates to NASA’s LRO team to help refine their follow-up imaging sequence. Comparing their new crater images with the pre-impact images, the LRO team updated the crater center coordinates: 19.4759°N, 266.7138°E, 511 meters elevation.

NASA’s next Gateways to Blue Skies competition invites collegiate teams to imagine innovative new ways aircraft could inspect land-based infrastructure, such as bridges and tunnels, to improve safety, reliability, and costs by 2035 or sooner.

Infrastructure is the foundation of the nation’s strong economy, global competitiveness, and daily quality of life. When that infrastructure is damaged or in disrepair, it restricts the movement of people, goods, and critical resources like water and energy. Inspections are important throughout the lifetime of infrastructure projects, but they often come with challenges.

Structures such as tunnels, bridges, highways, railways, and electric grids can be massive in size and difficult to reach. They can require disruptive shutdowns to access, or force workers to navigate extreme heights, confined spaces, and hazardous environments. As infrastructure ages and expands, there are opportunities to use innovative airborne platforms to improve current inspection practices.

“The demands for creative solutions like airborne platforms to improve the infrastructure sector are increasing exponentially,” said Steven Holz, Gateways to Blue Skies competition lead, NASA’s Langley Research Center in Hampton, Virginia. “The time is ripe for innovative students to transform how we work with our critical infrastructure, and this competition gives talented students the opportunity to do so.”

Sponsored by NASA’s University Innovation Project, the 2027 Gateways to Blue Skies competition encourages multidisciplinary teams of college students to conceptualize innovations in the world of aviation. Each year, the competition selects a new theme based on a complex challenge facing the Nation. It aims to engage as many students as possible from all backgrounds, majors, and collegiate levels.

The competition is open to teams of two to six students and divided into two phases. In Phase 1, teams will submit a proposal and an accompanying two-minute video, which will be judged by NASA and industry experts. Up to eight finalist teams will each receive a $9,000 prize and advance to Phase 2, where they will present their updated work to a panel of NASA and industry experts at a forum in May 2027. Winners will be offered the opportunity to intern with NASA Aeronautics in the academic year following the forum.

Teams interested in participating in the competition can review guidelines and eligibility requirements posted on the competition website. Teams are encouraged to submit a non-binding Notice of Intent by Monday, Oct. 12, via the website to stay apprised of competition news. Proposal and video submissions are due Feb. 22, 2027. The Gateway to Blue Skies Competition is run by the Aeronautics Division in NASA’s Research and Technology Mission Directorate. NASA’s Center of Excellence for Collaborative Innovation, part of the Prizes, Challenges, and Crowdsourcing Program within the Research and Technology Mission Directorate, manages the challenge contract. The National Institute of Aerospace administers the challenge on behalf of NASA.
