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.

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)
When most people think of NASA, they picture rockets, astronauts, and the Moon. But behind the scenes, a group of inventors is quietly rewriting the rules of what’s possible — on Earth, in orbit, and beyond. Their groundbreaking inventions eventually become technology available for industry, helping to shape new products and services that improve life around the globe. For their contributions to NASA technology, we welcome four new inductees into the 2024-2025 NASA Inventors Hall of Fame
A robot for space and the workplace
Myron (Ron) Diftler led the team behind Robonaut 2 (R2), a humanoid robot developed with General Motors. The goal was to create a robot that could help humans both in space and on the factory floor. The R2 robot became the first humanoid robot in space aboard the International Space Station, and part of its technology was licensed for use on Earth, leading to a grip-strengthening robotic glove to help humans with strenuous, repetitive tasks. From factories to space exploration, Diftler’s work has real-world impact.
Some of the toughest electronic chips on and off Earth
Technology developed to one day explore the surface of Venus has to be tough enough to survive the planet where temperatures hit 860°F and the atmosphere is akin to battery acid. Philip Neudeck’s silicon carbide integrated circuits don’t just work — they ran for over 60 days in simulated Venus-like conditions. On Earth, these chips can boost efficiency in wireless communication systems, help make drilling for oil safer, and enable more practical electric vehicles.
From developing harder chip materials to unlocking new planetary missions, Neudeck is proving that the future of electronics isn’t just about speed — it’s about survival.
Hydrogen sensors that could go the distance on other worlds
Gary Hunter helped develop a hydrogen sensor so advanced it’s being considered for a future mission to Titan, Saturn’s icy moon. These and a range of other sensors he’s helped developed have applications that go beyond space exploration, such as factory floors here on Earth.
With new missions on the horizon and smarter sensors in development, Hunter is still pushing the boundaries of what NASA technology can do. Whether it’s Titan, the surface of Venus, or somewhere we haven’t dreamed of yet, this work could help shape the way to get there.
Advanced materials research to make travel safer
Advanced materials, such as foams and composites, are key to unlocking the next generation of manufacturing. From space exploration to industry, Erik Weiser spent years contributing his expertise to the development of polymers, ceramics, metals, nanomaterials, and more. He is named on more than 20 patents. During this time, he provided his foam expertise to the Space Shuttle Columbia accident investigation, the Shuttle Discovery Return-to-Flight Investigation and numerous teams geared toward improving the safety of the shuttle.
Today, Weiser serves as director of the Facilities and Real Estate Division at NASA Headquarters, overseeing the foundation of NASA’s missions. Whether it’s advancing research or optimizing real estate across the agency, he’s helping launch the future, one facility at a time.

A first-generation college graduate, Nilufar Ramji was blazing trails long before arriving at NASA. With her multifaceted expertise, she is helping shape the messaging behind humanity’s return to the Moon, Mars, and beyond.
Ramji is currently on detail as the co-executive producer for NASA’s live broadcasts, ensuring the agency’s missions and discoveries are clearly and effectively communicated to the public. Through her work, she expands understanding of what space exploration means for all—and why it matters.
Official portrait of Nilufar Ramji. NASA/Josh Valcarcel Before stepping into her acting role, Ramji served as the lead public affairs officer for Moon to Mars activities at NASA’s Johnson Space Center in Houston. She spearheaded communication strategies for the Commercial Lunar Payload Services initiative, which works with private companies to deliver science and technology payloads to the lunar surface. She has also provided live commentary for International Space Station operations to learn and prepare for Artemis missions.
Ramji played a pivotal role in communicating NASA’s involvement in two major lunar missions in 2025 including Firefly Aerospace’s Blue Ghost Mission 1 which successfully delivered 10 NASA payloads to the Moon’s Mare Crisium on March 2. Ramji served as the live mission commentator, helping audiences around the world follow the historic moment—from lunar orbit insertion to touchdown. She also led communications for Intuitive Machines’ IM-2 mission, which landed near the Moon’s South Pole on March 6, marking the southernmost lunar landing ever achieved.

NASA/Helen Arase Vargas Early in her NASA career, she led agencywide STEM communications, shaping how NASA connects with students and educators. As a lead strategist, she developed messaging that made science and technology more accessible to younger audiences—helping inspire the Artemis Generation.
“Being one of the storytellers behind humanity’s return to the Moon is something I take pride in,” she said. “People don’t realize what exploring our solar system has done for us here on Earth. Going to the Moon and onto Mars will bring that message home.”
Nilufar Ramji, left, and Aliyah Craddock, digital media lead for NASA Science in the Science Mission Directorate, in the Astromaterials Research and Exploration Science laboratory at NASA’s Johnson Space Center in Houston. NASA Ramji communicates not just the science of space, but its greater significance. “How can we be thoughtful in our communications?” is a question that drives her approach. Whether guiding a live broadcast or developing messaging about lunar science, she is constantly evaluating, executing, and refining NASA’s voice.
She also understands the importance of commercial partnerships in expanding human presence in space. “It’s exciting to see how many different people and organizations come together to make this a reality,” she said. “By creating a larger space economy, we’re able to do things faster and cheaper and still accomplish the same goals to make sure we’re all successful.”
Nilufar Ramji presents a TedX Talk, “Storytelling from Space” in Sugar Land, Texas. In Aug. 2023, Ramji delivered a TEDx Talk, “Storytelling from Space” in Sugar Land, Texas, where she emphasized the power of narrative to inspire and unite humanity in the quest to explore the universe. Drawing from her NASA experience, she illustrated how communication bridges the gap between complex science and public engagement.
She credits her mentors and colleagues for supporting her growth. “I have great mentors and people I can lean on if I need help,” she said. “It’s something I didn’t realize I had until I came to NASA.”
Ramji believes stepping outside your comfort zone is essential. “Discomfort brings new learning, understanding, and opportunities, so I like being uncomfortable at times,” she said. “I’m open and receptive to feedback. Constructive criticism has helped me grow and evolve—and better understand NASA’s mission.”
For her, balance means creating intentional space for reflection, growth, and meaningful connection.
Nilufar Ramji gives remarks during Johnson’s building naming ceremony of the “Dorothy Vaughan Center in Honor of the Women of Apollo” on July 19, 2024. NASA/Robert Markowitz Before joining NASA, Ramji had already built an international career rooted in service. She worked at the Aga Khan Foundation in Canada, a nonprofit organization focused on addressing challenges in underdeveloped communities through education and healthcare.
She led visitor programs, workshops and more than 250 events—often for diplomats and global leaders—to promote “quiet diplomacy” and dialogue.
“Transparency, quality, fairness and diversity of perspective are all important to me,” she said. “People come from different experiences that broaden our understanding.”
Ramji later moved to East Africa as the foundation’s sole communications representative across Kenya, Tanzania, and Uganda. There, she trained more than 300 staff and built a communications strategy to help local teams share stories of impact—both successes and challenges—with honesty and empathy.
Her work left a lasting mark on the communities she served and underscored the power of communication to drive positive change.
Nilufar Ramji captures the story of a sesame farmer in Mtwara, Tanzania, whose livelihood improved through a rural development program initiated by the Aga Khan Foundation. In 2013, Ramji moved to the United States and started over, rebuilding her network and career. She worked for the Aga Khan Council for USA in Houston, leading a volunteer recruitment program that connected thousands of people with roles suited to their skills.
She later applied for a contractor position—not knowing it was with NASA. “I never thought my skills or expertise would be valued at a place like NASA,” she said. But in 2018, she accepted a role as a public relations specialist supporting International Space Station outreach. She has been shaping the agency’s storytelling ever since.
Ramji’s journey represents NASA’s commitment to pushing boundaries and expanding humanity’s knowledge of the universe. With collaboration, transparency, and vision, she is helping bring the next frontier of space exploration to life.

Sometimes an unexpected turn in a carefully planned career path leads to surprising opportunities for growth and exciting new experiences. For Jason Phillips, that turn steered toward NASA’s Johnson Space Center in Houston.
Official portrait of Jason Phillips.NASA/Bill Stafford Phillips joined the U.S. Air Force in 1994 and planned to serve for at least 20 years, but in 2010—while preparing for a third deployment after 14 years of service—he found himself facing a medical separation from the military. “In a very short amount of time I had to figure out next steps for a career and lifestyle that no longer involved being an active duty servicemember,” he said.
Thanks to a special hiring authority obtained by Peterson Air Force Base’s Office of Procurement, Phillips was able to transition to the civil service and apply his experience as an Air Force contracting officer to a new role. Phillips returned home to Houston and shifted from a Defense Department job to NASA as a contract specialist, spending his first 10 years at Johnson supporting all aspects of the Center Operations Directorate. He was then tasked with the challenge of serving as a lead contracting officer within Johnson’s procurement office for the International Space Station Program.
Phillips currently leads a team of highly skilled acquisition professionals who support a variety of contracts that sustain the International Space Station’s operations, maximize science conducted aboard the orbiting laboratory, and pave the way for a seamless transition to commercial low Earth orbit destinations. He oversees the team’s daily work, which includes strategic planning and acquisition of contracts valued at more than $21 billion. Specifically, the team handles NASA’s Cargo Resupply Services contracts, a cooperative agreement with the Center for the Advancement of Science in Space, and the Research, Engineering & Mission Integration Services-2 contract.
Jason Phillips (left) and Johnson Office of Procurement colleagues attend a National Contract Management Association conference at the Gilruth Center in 2016. NASA/James Blair “I am responsible for providing high-quality procurement products, services, and support to ensure that executive and technical customer needs are met and exceeded while maintaining compliance with applicable statutes, regulations, and guidelines,” he said. That work has included modifying the program’s original acquisition strategy to minimize delays, target cost savings, and emphasize critical infrastructure and services such as the Environmental Control and Life Support Systems aboard the space station.
Phillips enjoys seeing the direct impact of his work. “This career field almost always allows me to see the fruits of my labor, whether I am procuring office supplies and equipment or managing construction projects,” he said, noting that the remodeling of Johnson’s building 20 was his first project at the center. He is also proud to have supported the career progression of fellow procurement professionals and technical staff. “It’s a nod to those who came before me and provided me with their leadership and technical knowledge of procurement.”
Jason Phillips received an Individual Contribution Award for continuous support in Johnson’s Office of Procurement from NASA Assistant Administrator for Procurement Karla Jackson in 2022.NASA/Robert Markowitz Phillips said that staying humble and accountable is key to finding mission-focused solutions that benefit everyone. He also cautioned against making assumptions. “The people around you are very willing to offer thoughts and insights into a solution to your problem,” he said. “There is so much knowledge to be gained by listening.”
He encourages the Artemis Generation to seek opportunities to expand their technical knowledge and grow professionally. “Help yourself so that you may help others.”
