Preparations for Next Moonwalk Simulations Underway (and Underwater)
The SpaceX Dragon Freedom spacecraft carrying NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov approaches the International Space Station as it orbited 261 miles above Ontario, Canada, near James Bay. NASA published a new report Thursday highlighting 17 agency mechanisms that have directly and indirectly supported the development and growth of the U.S. commercial space sector for the benefit of humanity.
The report, titled Enabling America on the Space Frontier: The Evolution of NASA’s Commercial Space Development Toolkit, is available on the agency’s website.
“This is the most extensive and comprehensive historical analysis produced by NASA on how it has contributed to commercial space development over the decades,” said Alex MacDonald, NASA chief economist. “These efforts have given NASA regular access to space with companies, such as SpaceX and Rocket Lab, modernizing our communications infrastructure, and even led to the first private lunar lander thanks to Intuitive Machines. With commercial space growth accelerating, this report can help agency leaders and stakeholders assess the numerous mechanisms that the agency uses to support this growth, both now and in the future.”
Throughout its history, NASA has supported the development of the commercial space sector, not only leading the way in areas such as satellite communications, launch, and remote sensing, but also developing new contract and operational models to encourage commercial participation and growth. In the last three decades, NASA has seen the results of these efforts with commercial partners able to contribute more to missions across NASA domains, and increasingly innovative agency-led efforts to engage, nurture, and integrate these capabilities. These capabilities support the agency’s mission needs, and have seen a dramatic rise in importance, according to the report.
NASA has nurtured technology, companies, people, and ideas in the commercial space sector, contributing to the U.S. and global economies, across four distinct periods in the agency’s history:
1915–1960: NASA’s predecessor, the National Advisory Committee on Aeronautics (NACA), and NASA’s pre-Apollo years. 1961–1980: Apollo era. 1981–2010: Space shuttle era. 2011–present: Post-shuttle commercial era. Each of these time periods are defined by dominant technologies, programs, or economic trends further detailed in the report.
Though some of these mechanisms are relatively recent, others have been used throughout the history of NASA and NACA, leading to some overlap. The 17 mechanisms are as follows:
Contracts and Partnership Agreements Research and Technology Development (R&TD) Dissemination of Research and Scientific Data Education and Workforce Development Workforce External Engagement and Mobility Technology Transfer Technical Support Enabling Infrastructure Launch Direct In-Space Support Standards and Regulatory Framework Support Public Engagement Industry Engagement Venture Capital Engagement Market Stimulation Funding Economic Analysis and Due Diligence Capabilities Narrative Encouragement NASA supports commercial space development in everything from spaceflight to supply chains. Small satellite capabilities have inspired a new generation of space start-ups, while new, smaller rockets, as well as new programs are just starting. Examples include CLPS (Commercial Lunar Payload Services), commercial low Earth orbit destinations, human landing systems, commercial development of NASA spacesuits, and lunar terrain vehicles. The report also details many indirect ways the agency has contributed to the vibrance of commercial space, from economic analyses to student engagement.
The agency’s use of commercial capabilities has progressed from being the exception to the default method for many of its missions. The current post-shuttle era of NASA-supported commercial space development has seen a level of technical development comparable to the Apollo era’s Space Race. Deploying the 17 commercial space development mechanisms in the future are part of NASA’s mission to continue encouraging commercial space activities.

If Digital Transformation were a ship, the vessel for delivering on our missions and ensuring smooth passage into the future, our final Digital Transformer of 2024 would be the captain. Growing up sailing with her father on the Chesapeake Bay, this transformer developed the navigation skills she now uses at NASA “with both clarity and precision, much like a sailor who understands the subtle shifts in the wind,” says Christina Haymes, DT Enterprise Integration Architect. “She knows how to watch the sea to find the invisible breeze,” notes Patrick Murphy, DT Portfolio Manager. “I admire how she operates as a leader both in calm and troubling seas to get us where we want to be.” Vision and leadership are just two of the many reasons why our December Digital Transformer, Jill Marlowe, stands at the helm of our ever-evolving journey.
Jill has dedicated over three decades to her career at NASA, starting as an engineer and evolving into her position as the Digital Transformation Officer. Her early sailing experiences led her to pursue ocean and aerospace engineering at Virginia Tech; an innate passion for continual growth led to subsequent master’s degrees in mechanical, civil, and environmental engineering. As Jill moved into leadership positions across NASA’s engineering organizations, divisions, and directorates, she realized that the technology she was instinctively using to transform her work could also help the agency overcome a wider range of challenges.
Her keen eye for cross-cutting solutions perfectly positioned her for the dynamic role of Digital Transformation Officer, diving into technical problems with engineers one day and strategizing with senior executives the next. Although she brings a rigorous technical background to the role, Jill most enjoys the creative and collaborative aspects. “It really gives me an opportunity to engage with a lot of earlier career folks who often are bringing some of these digital ideas into our workplace,” she says. “To me, it’s a very generative role, and that’s what I like the best about it.”
Jill commits to practicing what she preaches, strategically leveraging tools like Microsoft Teams and other M365 applications to build a culture of digital innovation and influence others to join the movement. Krista Kinnard, DT Culture and Communications Lead, says, “We work in a digital world with new tools that make our lives easier. Jill has really shown how the way we interact with each other matters and can be streamlined to drive our team to success.” Jill’s growth-oriented mindset drives her to stay on the cutting edge of new capabilities—always with the goal of enabling mission outcomes and increasing our capacity for partnership.
When times are challenging, people want heroes. I think a lot of what NASA does is bring humanity together.
Jill Marlowe
Digital Transformation Officer
Jill’s fervent belief in the power of collaboration is evident in the way she talks about her technical work, particularly with Digital Engineering (DE). “I am very excited about where we are with digital engineering at NASA and the progress Terry Hill and his team have made [toward] a unified engineering community,” says Jill. Through seed funding and ongoing support, Jill and the DT team grew Digital Engineering at NASA from initial prototype tests to an operationalized program within the Office of the Chief Engineer. In addition to the community’s alignment around a shared vision, Jill is proud of the team’s quantitative achievements in developing systems, tools, and approaches for digitalizing the engineering processes and adopting a common toolchain. “I feel like we’ve been talking about those kinds of ideas my entire career, and we’re this close to having this in the hands of the engineers across NASA so they can work together and with our partners in ways that we haven’t been able to before”
For Jill, the measure of DT’s success lies in the ability to enable more complex missions, collaborate more seamlessly with partners, and build more resilient systems that prepare us for the future. Under her leadership, DT facilitated the maturation of NASA Mission Cloud, a digital solution for capturing mission capability requirements and defining technology needs. In FY24, DT launched the new IT Modernization for Transformation (ITMX) fund and curated a $10M portfolio of enterprise solutions in data interoperability, federated search, digital engineering, cybersecurity, artificial intelligence, and more. By championing Digital Transformation at NASA and demonstrating its value, Jill paved the way for solutions that accelerate discovery and mission delivery.
Over her career, Jill forged bonds, championed innovation, and positioned the agency to leverage the ripple effects of her work long after her upcoming retirement in December. Her legacy, however, might be best summarized by the way she made people feel. “It sounds simple, but so many people are listening to respond, whereas Jill is listening to understand,” Krista says. The rest of DT leadership echoes this sentiment. “Jill has a deep knowledge of NASA and has built strong relationships across the agency. Most of all, I value her mentorship and friendship,” says Christina. Patrick puts it simply: “Collaborating with Jill is a joy.”
As she reflects on her time at the agency, Jill shares inspiring aspirations for NASA’s future and DT’s ability to carry us on that voyage. “When times are challenging, people want heroes. I think a lot of what NASA does is bring humanity together. When I think about those big expectations on NASA for the future and the technology that’s coming along that can make those dreams come true…it literally gives me chills.” She continues, “I encourage the continued community around Digital Transformation, the continued quest to find shared solutions to common challenges. Because I really do think that’s the way we’re going to get there from here.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Knowing whether or not a planet elsewhere in the galaxy could potentially be habitable requires knowing a lot about that planet’s sun. Sarah Peacock relies on computer models to assess stars’ radiation, which can have a major influence on whether or not one of these exoplanets has breathable atmosphere.
Name: Sarah Peacock
Title: Assistant Research Scientist
Formal Job Classification: Astrophysicist
Organization: Exoplanets and Stellar Astrophysics Laboratory, Astrophysics Division, Science Directorate (Code 667)
Sarah Peacock is a research scientist with the Exoplanets and Stellar Astrophysics Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, Md.Courtesy of Sarah Peacock What do you do and what is most interesting about your role here at Goddard?
My overarching research goal is to find habitable planets in other solar systems. To do this, I study the high-energy radiation that specific stars produce to help determine if life can exist on any earthlike planets that orbit them.
What is your educational background?
In 2013, I received a Bachelor of Arts in astrophysics from the University of Virginia. I received both my master’s and doctorate degrees from the Lunar and Planetary Laboratory at the University of Arizona in 2016 and 2019, respectively.
What drew you to study the stars?
In high school, I took an astronomy class. We had a planetarium in our school and I had a wonderful teacher who inspired me to fall in love with the stars. She also showed us how many of the Harry Potter characters are drawn from the constellations and that spoke to my heart because I am a Harry Potter fan!
How did you come to Goddard?
I started at Goddard as a NASA post-doctoral fellow in July 2020, but I first saw the center the day before Goddard shut down due to COVID.
How does high-energy radiation show you what planets outside our solar system might be habitable?
High-energy radiation can cause a planet to lose its atmosphere. If a planet is exposed to too much high-energy radiation, the atmosphere can be blown off, and if there is no atmosphere, then there is nothing for life as we know it to breathe.
We cannot directly measure the specific radiation that I study, so we have to model it. The universe has so many stars, and almost all stars host a planet. There are approximately 5,500 confirmed exoplanets so far, with an additional 7,500 unconfirmed exoplanets.
I help identify systems that either have too much radiation, so planets in the habitable zone (the region around a star where liquid water could exist on a planet’s surface) are probably lifeless, or systems that have radiation levels that are safer. Ultimately, my research helps narrow down the most likely systems to host planets that should have stable atmospheres.
Sarah Peacock research goal is to find habitable planets in other solar systems.Courtesy of Sarah Peacock Where does your data come from?
I predominately use data from the Hubble Space Telescope and from the now-retired spacecraft GALEX. My work itself is more theory-focused though: I create a modeled stellar spectrum across all wavelengths and use observations to validate my modeling.
What other areas of research are you involved in?
I am working with a team analyzing data from the James Webb Space Telescope to see if earthlike planets around M-type stars (a star that is cooler and smaller than the Sun) have atmospheres and, if so, what the composition of those atmospheres is. An exciting result from this work is that we may have detected water in the atmosphere of a rocky planet for the first time ever. However, we cannot yet distinguish with our current observations if that water comes from the planet or from spots on the star (starspots on this host star are cold enough for water to exist in gas form).
I am also helping manage a NASA Innovative Advance Concept (NIAC) study led by my mentor, Ken Carpenter, to work on the Artemis Enabled Stellar Imager (AeSI). If selected for further development, this imager would be an ultraviolet/optical interferometer located on the South Pole of the Moon. With this telescope, we would be able to map the surface of stars, image accretion disks, and image the centers of Active Galactic Nuclei.
As a relatively new employee to Goddard, what have been your first impressions?
Everyone who I have met, especially those in my lab, are incredibly friendly and welcoming. Starting during the pandemic, I was worried about feeling isolated, but instead, I was blown away by how many folks in my lab reached out to set up calls to introduce themselves and suggest opportunities for collaboration. It made me feel welcome.
Who is your mentor and what did your mentor advise you?
Ken Carpenter is my mentor. He encourages me to pursue my aspirations. He supports letting me chart my own path and being exposed to many different areas of research. I thank Ken for his support and encouragement and for including me on his projects.
“Everyone who I have met, especially those in my lab, are incredibly friendly and welcoming.”Courtesy of Sarah Peacock What do you do for fun?
I am a new mom, so my usual hobbies are on pause! Right now, fun is taking care of my baby and introducing life experiences to him.
As a recently selected member of the Executive Committee for NASA’s Exoplanet Exploration Program Analysis Group (ExoPAG), what are your responsibilities?
The NASA ExoPAG is responsible for soliciting and coordinating scientific community input into the development and execution of NASA’s exoplanet exploration program. We solicit opinions and advice from any scientist who studies exoplanets. We are a bridge between NASA’s exoplanet scientists and NASA Headquarters in Washington.
What is a fun fact about yourself?
I got married the same day I defended my Ph.D. I had my defense in the morning and got married in the afternoon at the courthouse.
Who is your favorite author?
I love to read; I always have three books going. My favorite author is Louise Penny, who writes mysteries, but I read all genres. Right now, I am reading a biography about Marjorie Merriweather Post.
What is your favorite quote?
“The most that can be expected from any model is that it can supply a useful approximation to reality: All models are wrong; some models are useful.” —Box and Draper 1987
