Electrical and Mechanical Technician Clifton Brown

“We have a group photo of my first project here, ASTRO-H, and that one means a lot to me because I came [to that NASA project] fresh off the street. I was super scared and intimidated. It was me and three other [technicians], who were also all new, and a handful of very seasoned scientists and engineers. And we came together.

“And we actually came in — I believe — under budget, ahead of schedule, and exceeded all expectations for our test results. That’s kind of unheard of, you know what I mean? We had such a good environment in the lab. Everybody got along so well. It was all teamwork. And everything just gelled.

“So when I look back on that photo from 14 years ago, first of all, I look really young in it. And secondly, it makes me realize how blessed and lucky I’ve been to be here for so long. It reminds me of that guy who was really nervous and still did alright. [It reminds me] to have a little confidence in myself, just be me, and do the work. It’ll all work out.

“I love looking back at that first team photo and just remembering how raw everything was at the time and how well it still came out.”

NASA Barge Preparations Underway for Artemis II Rocket Stage Delivery

Team members are installing pedestals aboard NASA’s Pegasus barge to hold and secure the massive core stage of NASA’s SLS (Space Launch System) rocket, indicating NASA barge crews are nearly ready for its first delivery to support the Artemis II test flight around the Moon. The barge will ferry the core stage on a 900-mile journey from the agency’s Michoud Assembly Facility in New Orleans to its Kennedy Space Center in Florida.

The Pegasus crew began installing the pedestals July 10.The barge, which previously was used to ferry space shuttle external tanks, was modified and refurbished to compensate for the much larger and heavier core stage for the SLS rocket. Measuring 212 feet in length and 27.6 feet in diameter, the core stage is the largest rocket stage NASA has ever built and the longest item ever shipped by a NASA barge.

Pegasus now measures 310 feet in length and 50 feet in width, with three 200-kilowatt generators on board for power. Tugboats and towing vessels will move the barge and core stage from Michoud to Kennedy, where the core stage will be integrated with other elements of the rocket and prepared for launch. Pegasus is maintained at NASA Michoud.

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

Take a Summer Cosmic Road Trip With NASA’s Chandra and Webb

It’s time to take a cosmic road trip using light as the highway and visit four stunning destinations across space. The vehicles for this space get-away are NASA’s Chandra X-ray Observatory and James Webb Space Telescope.

The first stop on this tour is the closest, Rho Ophiuchi, at a distance of about 390 light-years from Earth. Rho Ophiuchi is a cloud complex filled with gas and stars of different sizes and ages. Being one of the closest star-forming regions, Rho Ophiuchi is a great place for astronomers to study stars. In this image, X-rays from Chandra are purple revealing infant stars that violently flare and produce X-rays. Infrared data from Webb are red, yellow, cyan, light blue and darker blue and provide views of the spectacular regions of gas and dust.

The next destination is the Orion Nebula. Still located in the Milky Way galaxy, this region is a little bit farther from our home planet at about 1,500 light-years away. If you look just below the middle of the three stars that make up the “belt” in the constellation of Orion, you may be able to see this nebula through a small telescope. With Chandra and Webb, however, we get to see so much more. Chandra reveals young stars that glow brightly in X-rays, colored in red, green, and blue, while Webb shows the gas and dust in darker red that will help build the next generation of stars here.

It’s time to leave our galaxy and visit another. Like the Milky Way, NGC 3627 is a spiral galaxy that we see at a slight angle. NGC 3627 is known as a “barred” spiral galaxy because of the rectangular shape of its central region. From our vantage point, we can also see two distinct spiral arms that appear as arcs. X-rays from Chandra in purple show evidence for a supermassive black hole in its center while Webb finds the dust, gas, and stars throughout the galaxy in red, green, and blue. This image also contains optical data from the Hubble Space Telescope in red, green, and blue.

Our final landing place on this trip is the farthest and the biggest. MACS J0416 is a galaxy cluster, which are among the largest objects in the Universe held together by gravity. Galaxy clusters like this can contain hundreds or even thousands of individual galaxies all immersed in massive amounts of superheated gas that Chandra can detect. In this view, Chandra’s X-rays in purple show this reservoir of hot gas while Hubble and Webb pick up the individual galaxies in red, green, and blue.

NASA’s Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science from Cambridge Massachusetts and flight operations from Burlington, Massachusetts.

Visual Description:

This release features four distinct composite images from NASA’s Chandra X-ray Observatory and the James Webb Space Telescope, presented in a two-by-two grid.

At our lower right is Rho Ophiuchi, a cloud complex filled with gas, and dotted with stars. The murky green and gold cloud resembles a ghostly head in profile, swooping down from the upper left, trailing tendrils of hair. Cutting across the bottom edge and lower righthand corner of the image is a long, narrow, brick red cloud which resembles the ember of a stick pulled from a fire. Several large white stars dot the image. Many are surrounded by glowing neon purple rings, and gleam with diffraction spikes.

At our upper right of the grid is a peek into the heart of the Orion Nebula, which blankets the entire image. Here, the young star nursery resembles a dense, stringy, dusty rose cloud, peppered with thousands of glowing golden, white, and blue stars. Layers of cloud around the edges of the image, and a concentration of bright stars at its distant core, help convey the depth of the nebula.

In the lower left of the two-by-two grid is a hazy image of a spiral galaxy known as NGC 3627. Here, the galaxy appears pitched at an oblique angle, tilted from our upper left down to our lower right. Much of its face is angled toward us, making its spiral arms, composed of red and purple dots, easily identifiable. Several bright white dots ringed with neon purple speckle the galaxy. At the galaxy’s core, where the spiral arms converge, a large white and purple glow identified by Chandra provides evidence of a supermassive black hole.

At the upper left of the grid is an image of the distant galaxy cluster known as MACS J0416. Here, the blackness of space is packed with glowing dots and tiny shapes, in whites, purples, oranges, golds, and reds, each a distinct galaxy. Upon close inspection (and with a great deal of zooming in!) the spiraling arms of some of the seemingly tiny galaxies are revealed in this highly detailed image. Gently arched across the middle of the frame is a soft band of purple; a reservoir of superheated gas detected by Chandra.

Acting Center Chief Technologist Dr. Phillip Williams

“I did not know that NASA Langley was right here in my own backyard. I was born and raised in Portsmouth, Virginia, and NASA Langley is in Hampton, about 45 minutes away. All throughout elementary school, I didn’t know that NASA was here. I always thought NASA was in Florida or Texas or somewhere.

“I was in this summer program [in eighth grade], learning physics at the university. I vividly remember we had a guest speaker. He was an African American mechanical engineer and he had on the blue flight suit. And he said he worked at NASA, and it just blew my mind.

“And at that point, I saw myself in him. I didn’t even know that NASA was here, so close to me, and I hadn’t seen anybody who had ever worked there. So that left a mark in my mind: ‘Wow, NASA is here.’

“… When I was in college, I came back to my high school to talk to a class about majoring in physics. And there was a student, maybe two years under me. I remember meeting her. I remember interacting. I remember talking with her just briefly at this career fair event.

“I found out years later that seeing me in high school and hearing my experience in college inspired her to major in physics, and so she became the first robotics director at her school. And now she’s a principal. And it just rocked me because I was just being me and trying to share. It seemed like I paid it forward the same way that NASA mechanical engineer made a mark on me.”

Voyagers of Mars: The First CHAPEA Crew’s Yearlong Journey 

When the first humans travel to the Red Planet, they will need to know how to repair and maintain equipment, grow their own food, and stay healthy, all while contending with Earth-to-Mars communication delays. They must also find ways to build comradery and have fun. 

The first all-volunteer CHAPEA (Crew Health and Performance Exploration Analog) crew accomplished all of that and more during their 378-day analog mission on the surface of Mars.  

Living in the isolated Mars Dune Alpha, a 3D-printed, 1,700-square-foot habitat, crew members Kelly Haston, Ross Brockwell, Nathan Jones, and Anca Selariu faced the rigors of a simulated Mars expedition, enduring stressors akin to those of a real mission to the Red Planet. They also celebrated holidays and birthdays, gave each other haircuts, and found moments of levity in isolation. Their journey will help scientists understand the challenges of deep space missions and offer invaluable insights into the resilience of the human spirit. 

As the crew concluded their journey on July 6, NASA astronaut and Deputy Director of Flight Operations Kjell Lindgren opened the habitat door and welcomed them home. 

“The crew and their families have committed a year of their lives in service to NASA, the country, and humanity’s exploration of space. Thank you to for committing yourselves to research that will enable our future exploration of space,” he said. “Your fingerprints are going to be an indelible part of those first footprints on Mars.” 

The CHAPEA crew brought their diverse backgrounds and experiences to the mission, collaborating with NASA’s scientists and engineers to collect data that will provide insight into maintaining crew health and performance for future missions to Mars. 

Kelly Haston: Mission Commander and Pioneering Scientist 

Haston, the mission commander, is a research scientist who builds human disease models. She has spearheaded innovative stem cell-based projects, deriving multiple cell types for work in infertility, liver disease, and neurodegeneration. Her role was pivotal in maintaining crew morale and ensuring the success of daily operations. 

She highlighted the importance of teamwork and adaptability in a mission with such high stakes.

“We had to rely on each other and our training to navigate the challenges we faced,” she said. “Every day brought new obstacles, but also new opportunities for growth and learning.” 

Nathan Jones: Medical Officer and Expert Communicator 

Jones, the crew medical officer, used his emergency and international medicine experience to tackle the unique challenges of the Mars mission. His expertise in problem-solving and effective communication in a time-sensitive and resource-limited environment was essential due to the approximately one-hour transmission delay. “Even something as simple as when to communicate is important,” said Jones. The crew had to consider what observations were essential to report to each other or Mission Control to avoid overburdening the team or unnecessarily using the limited bandwidth to Earth. 

“Everything we do in CHAPEA is touched by the heroes working on the ground at NASA,” he said. “We couldn’t ask for a better experience or better people to work with.” 

The experience evolved into a journey of personal growth for Jones. “I am constantly looking forward, planning for the future,” he said. “I learned to take time to enjoy the current season and be patient for the coming ones.” 

He also discovered a new hobby: art. “I have even surprised myself with how well some of my sketches have turned out,” he said. 

Anca Selariu: Microbiologist and Innovative Thinker 

Anca Selariu brought expertise as a microbiologist in the U.S. Navy, with a background in viral vaccine discovery, prion transmission, gene therapy development, and infectious disease research management. 

Selariu expressed that she owes much to the Navy, including her involvement in CHAPEA, as it helped shape her both personally and professionally. “I hope to bring back a fresh perspective, along with a strong inclination to think differently about a problem, and test which questions are worth asking before we set out answering them,” she said.  

Reflecting on the mission, Selariu said, “Every day seemed to be a new revelation about something; about Earth, about art, about humans, about cultures, about the history of life in the universe – what little we know of it.” 

She added, “As much as I appreciate having information at my fingertips, I will miss the luxury of being unplugged in a world that now validates humans by their digital presence.”  

Ross Brockwell: Structural Engineer and Problem Solver 

Brockwell, the mission’s flight engineer, focused on infrastructure, building design, and organizational leadership. His structural engineering background influenced his approach to problem solving in the CHAPEA habitat. 

“An engineering perspective leads you to build an understanding of how things will react and interact, anticipate possible failure points, and ensure redundancy and contingency planning,” he said. 

That mindset helped the crew develop creative solutions to mission challenges, such as using a 3D printer to design part adapters and tools and find ways to connect as a team. “Several things we wanted to do for fun required innovation, one being developing a bracket so we could safely and securely mount our mini-basketball hoop,” he said. 

He advises Artemis Generation members interested in contributing to future analog missions to think about systems engineering theory and learn to develop and integrate whole systems while solving individual challenges.  

Brockwell believes the most important attributes for a CHAPEA crew member are imagination and a strong sense of wonder. “Of course, one needs to have patience, self-control, emotional regulation, and a sense of humor,” he said. “I would also add perspective, which means understanding the importance of exploration missions on behalf of humankind and appreciating being part of something greater than oneself.” 

A Vision for the Future 

As the first CHAPEA mission concludes, the data collected and experiences shared by the crew will pave the way for future explorations, bringing humanity one step closer to setting foot on Mars.  

“One of the biggest things I have learned on this long-duration mission is that we should never underestimate the effects of small gains over time,” said Jones. “Be willing to do the hard things now and it may make all the difference for the future.” 

Selariu emphasized the importance of interdisciplinary collaboration in upcoming space missions. “What everyone at CHAPEA seems to have in common is passion for space and drive to pursue it no matter the challenges, inconvenience, and personal sacrifices.” 

Brockwell looks forward to missions to the Red Planet becoming a reality. “It still fills me with awe and excitement to think that one day there will be people on the surface of other worlds, overcoming immense challenges and expanding the existence and awareness of life from Earth.”
