Preparations for Next Moonwalk Simulations Underway (and Underwater)
Christine Braden values new experiences that broaden her perspective; a mindset that has guided her 26-year career at NASA’s Johnson Space Center in Houston, where she currently serves as a senior systems engineer in the Commercial Low Earth Orbit Development Program. In her role, Braden works with engineering teams to develop commercial space stations that will prioritize the safety of astronauts while maximizing cost-effectiveness and the scientific research capabilities onboard.
Managed by NASA’s Space Operations Mission Directorate, the program supports the development of commercially owned and operated space stations in low Earth orbit from which the agency, along with other customers, can purchase services and stimulate the growth of commercial activities in space. Designing and developing these space stations is the first step of NASA’s two-phase approach, enabling the agency to certify stations and procure services as one of many customers.
With a bachelor’s degree in Technical Management from Embry-Riddle Aeronautical University, Braden brings a strong engineering foundation to her work. However, her role unique because it allows her to merge technical expertise with her creative instincts.
“My team must think outside the box to define new ways that ensure that the commercial providers’ technical integrations, requirements, development, and operations are designed to the highest degree possible,” said Braden.
Recently, she proposed a certification and systems engineering architecture that redefines how companies will interface with NASA and each other in an evolving landscape. Braden’s hybrid approach strikes a balance, allowing companies to innovate while favoring shared assurance and accountability. It also gives NASA situational awareness of the companies’ design, tests, mission, and operational approaches. As a result of her efforts, Braden was recognized with an “On the Spot” award.

Looking ahead, Braden envisions a world where commercial space stations are a hub for science and technology, spacecraft are more efficient, spaceflight is more accessible, humans are back on the Moon, and Mars is the next frontier. In reflecting on these agency-wide goals, Braden finds that working with passionate team members makes her day-to-day work truly special and enjoyable.
“I am a part of a small, close-knit team that works together to make these advancements in space exploration happen for the world,” said Braden. “Working at NASA is a once-in-a-lifetime opportunity that not only defines my working life going forward but also provides me with an experience I can share with some truly amazing people.”

Outside of work, Braden is inspired by her faith, which encourages her to see things from new perspectives and try to understand people from all walks of life. Additionally, Braden is a lifelong learner who loves listening to podcasts, watching documentaries, and reading web articles. She is eager to learn everything from music and dance to plants and animals.
“When I look through scientific websites where new planets and galaxies are discovered, it makes me think of ways humanity may expand itself to the stars, and ways that we can preserve the life we have here on Earth,” said Braden.
On the topic of preservation, one of Braden’s many hobbies is antique restoration. “It reminds me of my dad and grandfather restoring homes together during my childhood and gives me hope that I can inspire my children as they watch me follow in our family’s footsteps,” said Braden. Her other hobbies include gardening and family activities such as puzzles, board games, watching television, playing video games, hunting, and traveling.
As a driven individual known for her creativity and curiosity, Braden’s fresh ideas and spirit are key in guiding the agency’s progress into new frontiers.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Will the Sun ever burn out?
Well, the Sun, just like the stars we see at night, is a star. It’s a giant ball of super hot hydrogen.
Gravity squeezes it in and it creates energy, which is what makes the Sun shine. Eventually, it will use up all of that hydrogen. But in the process, it’s creating helium. So it will then use the helium. And it will continue to use larger and larger elements until it can’t do this anymore.
And when that happens, it will start to expand into a red giant about the size of the inner planets. Then it will shrink back down into a very strange star called a white dwarf — super hot, but not very bright and about the size of the Earth.
But our Sun has a pretty long lifetime. It’s halfway through its 10-billion-year lifetime.
So the Sun will never really burn out, but it will change and be a very, very different dim kind of star when it reaches the end of its normal life.

For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. The full artist’s concept illustration and full caption is shown below. Credits:
NASA, ESA, CSA, Ralf Crawford (STScI) Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system.
Now there is definitive evidence: Researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star 155 light-years away using detailed data known as spectra from NASA’s James Webb Space Telescope. (The term water ice specifies its makeup, since many other frozen molecules are also observed in space, such as carbon dioxide ice, or “dry ice.”) In 2008, data from NASA’s retired Spitzer Space Telescope hinted at the possibility of frozen water in this system.
“Webb unambiguously detected not just water ice, but crystalline water ice, which is also found in locations like Saturn’s rings and icy bodies in our solar system’s Kuiper Belt,” said Chen Xie, the lead author of the new paper and an assistant research scientist at Johns Hopkins University in Baltimore, Maryland.
All the frozen water Webb detected is paired with fine dust particles throughout the disk — like itsy-bitsy “dirty snowballs.” The results published Wednesday in the journal Nature.
Astronomers have been waiting for this definitive data for decades. “When I was a graduate student 25 years ago, my advisor told me there should be ice in debris disks, but prior to Webb, we didn’t have instruments sensitive enough to make these observations,” said Christine Chen, a co-author and associate astronomer at the Space Telescope Science Institute in Baltimore. “What’s most striking is that this data looks similar to the telescope’s other recent observations of Kuiper Belt objects in our own solar system.”
Water ice is a vital ingredient in disks around young stars — it heavily influences the formation of giant planets and may also be delivered by small bodies like comets and asteroids to fully formed rocky planets. Now that researchers have detected water ice with Webb, they have opened the door for all researchers to study how these processes play out in new ways in many other planetary systems.
Image: Debris Disk Around Star HD 181327 (Artist’s Concept)
For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. All the frozen water detected by Webb is paired with fine dust particles throughout the disk. The majority of the water ice observed is found where it’s coldest and farthest from the star. The closer to the star the researchers looked, the less water ice they found. NASA, ESA, CSA, Ralf Crawford (STScI) Rocks, Dust, Ice Rushing Around
The star, cataloged HD 181327, is significantly younger than our Sun. It’s estimated to be 23 million years old, compared to the Sun’s more mature 4.6 billion years. The star is slightly more massive than the Sun, and it’s hotter, which led to the formation of a slightly larger system around it.
Webb’s observations confirm a significant gap between the star and its debris disk — a wide area that is free of dust. Farther out, its debris disk is similar to our solar system’s Kuiper Belt, where dwarf planets, comets, and other bits of ice and rock are found (and sometimes collide with one another). Billions of years ago, our Kuiper Belt was likely similar to this star’s debris disk.
“HD 181327 is a very active system,” Chen said. “There are regular, ongoing collisions in its debris disk. When those icy bodies collide, they release tiny particles of dusty water ice that are perfectly sized for Webb to detect.”
Frozen Water — Almost Everywhere
Water ice isn’t spread evenly throughout this system. The majority is found where it’s coldest and farthest from the star. “The outer area of the debris disk consists of over 20% water ice,” Xie said.
The closer in the researchers looked, the less water ice they found. Toward the middle of the debris disk, Webb detected about 8% water ice. Here, it’s likely that frozen water particles are produced slightly faster than they are destroyed. In the area of the debris disk closest to the star, Webb detected almost none. It’s likely that the star’s ultraviolet light vaporizes the closest specks of water ice. It’s also possible that rocks known as planetesimals have “locked up” frozen water in their interiors, which Webb can’t detect.
This team and many more researchers will continue to search for — and study — water ice in debris disks and actively forming planetary systems throughout our Milky Way galaxy. “The presence of water ice helps facilitate planet formation,” Xie said. “Icy materials may also ultimately be ‘delivered’ to terrestrial planets that may form over a couple hundred million years in systems like this.”
The researchers observed HD 181327 with Webb’s NIRSpec (Near-Infrared Spectrograph), which is super-sensitive to extremely faint dust particles that can only be detected from space.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
