As associate administrator, Free has been the senior advisor to NASA Acting Administrator Janet Petro and leads NASA’s 10 center directors, as well as the mission directorate associate administrators at NASA Headquarters in Washington. He is the agency’s chief operating officer for more than 18,000 employees and oversaw an annual budget of more than $25 billion.
During his tenure as associate administrator since January 2024, NASA added nearly two dozen new signatories of the Artemis Accords, enabled the first Moon landing through the agency’s CLPS (Commercial Lunar Payload Services) initiative to deliver NASA science to the lunar surface, launched the Europa Clipper mission to study Jupiter’s icy ocean moon, and found molecules containing the ingredients for life in samples from asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security–Regolith Explorer) spacecraft.
“Throughout his career, Jim has been the ultimate servant leader – always putting the mission and the people of NASA first,” said Petro. “A remarkable engineer and a decisive leader, he combines deep technical expertise with an unwavering commitment to this agency’s mission. Jim’s legacy is one of selfless service, steadfast leadership, and a belief in the power of people.”
Among the notable contributions to the nation during his NASA career, Free also championed a new path forward to return samples from Mars ahead of human missions to the Red Planet, supported the crews living and working aboard the International Space Station as they conduct hundreds of experiments and technology demonstrations, and engaged industry in new ways to secure a public/private partnership for NASA’s VIPER (Volatiles Investigating Polar Exploration Rover) mission on the Moon.
“It has been an honor to serve NASA and walk alongside the workforce that tackles the most difficult engineering challenges, pursues new scientific knowledge in our universe and beyond, develops technologies for future exploration endeavors, all while prioritizing safety every day for people on the ground, in the air, and in space,” Free said. “I am grateful for the opportunity to be part of the NASA family and contribute to the agency’s mission for the benefit of humanity.”
During his more than three decades of service, Free has held several leadership roles at the agency. Before being named NASA associate administrator, Free served as associate administrator of the Exploration Systems Development Mission Directorate, where he oversaw the successful Artemis I mission and the development of NASA’s Moon to Mars architecture, defining and managing the systems development for the agency’s Artemis missions and planning for NASA’s integrated deep space exploration approach.
Free began his NASA career in 1990 as an engineer, working on Tracking and Data Relay Satellites at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. He later transferred to the agency’s Glenn Research Center in Cleveland and served in a variety of roles supporting the International Space Station and the development of the Orion spacecraft before transferring to NASA’s Johnson Space Center in Houston in 2008. Free returned to NASA Glenn in 2009 and was promoted to chief of the Space Flight Systems Directorate, where he oversaw the center’s space work. Free was named deputy center director in November 2010 and then served as center director from January 2013 until March 2016, when he was appointed to the NASA Headquarters position of deputy associate administrator for Technical [sic] in the Human Exploration and Operations Mission Directorate.
A native of Northeast Ohio, Free earned his bachelor’s degree in aeronautics from Miami University in Oxford, Ohio, and his master’s degree in space systems engineering from Delft University of Technology in the Netherlands.
Free is the recipient of the Presidential Rank Award, NASA Distinguished Service Medal, NASA Outstanding Leadership Medal, NASA Exceptional Service Medal, NASA Significant Achievement Medal, and numerous other awards.

An Afternoon of Family Science and Rocket Exploration in Alaska
On Tuesday, January 28th, Fairbanks BEST Homeschool joined the Geophysical Institute for an afternoon of rocket exploration, hands-on activities, and stargazing inside a planetarium. This event was free and open to the public. Despite their frigid winter weather, 200 attendees were curious about the scientific endeavors of Alaska-based researchers alongside cutting-edge investigations conducted by NASA rocket scientists.
Families and friends in attendance learned about two NASA rocket missions that would study the flickering and vanishing auroras: Ground Imaging to Rocket investigation of Auroral Fast Features (GIRAFF) and Black and Diffuse Aurora Science Surveyor (BaDASS). Visitors had an opportunity to sign up for text notifications related to the launch window. The planetarium presentations touch on Heliophysics Big Ideas that align with the three questions that drive NASA’s heliophysics research:
What are the impacts of the changing sun on humanity? How do Earth, the solar system, and the heliosphere respond to changes on the sun? What causes the sun to vary? The event also offered sun-related hands-on activities provided by the University of Alaska Museum of the North.
This event was offered to the community in association with the Science For Alaska Lecture Series and the 2025 NASA Sounding Rocket campaign. Every attendee left with something inspiring to think about. Parents and educators interested in learning more about auroras and do participatory science may check out NASA’s Aurorasaurus citizen science project.
The Geophysical Institute at the University of Alaska Fairbanks is a Co-Investigating team for the NASA Heliophysics Education Activation Team (NASA HEAT), which is part of NASA’s Science Activation Portfolio.

NASA’s Artemis campaign will send astronauts, payloads, and science experiments into deep space on NASA’s SLS (Space Launch System) super heavy-lift Moon rocket. Starting with Artemis IV, the Orion spacecraft and its astronauts will be joined by other payloads atop an upgraded version of the SLS, called Block 1B. SLS Block 1B will deliver initial elements of a lunar space station designed to enable long term exploration of the lunar surface and pave the way for future journeys to Mars. To fly these advanced payloads, engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are building a cone-shaped adapter that is key to SLS Block 1B.
At NASA Marshall, the PLA engineering development unit is installed into the 4697-test stand for structural testing. It was then attached to the large cylindrical structure which simulates the Exploration Upper Stage interface. Load lines were then connected to the top of the PLA. The testing demonstrated that it can handle up to three times the expected load.NASA/Samuel Lott The payload adapter, nestled within the universal stage adapter sitting atop the SLS Block 1B’s exploration upper stage, acts as a connecting point to secure a large payload that is co-manifested – or flying along with – the Orion spacecraft. The adapter consists of eight composite panels with an aluminum honeycomb core and two aluminum rings.
Beginning with the Artemis IV mission, SLS Block 1B will feature a new, more powerful upper stage that provides a substantial increase in payload mass, volume, and energy over the first variant of the rocket that is launching Artemis missions I through III. SLS Block 1B can send 84,000 pounds of payload – including both a crewed Orion spacecraft and a 10-metric ton (22,046 lbs.) co-manifested payload riding in a separate cargo compartment – to the Moon in a single launch.
Artemis IV’s co-manifested payload will be the Lunar I-Hab, one of the initial elements of the Gateway lunar space station. Built by ESA (European Space Agency), the Lunar I-Hab provides expanded capability for astronauts to live, work, conduct science experiments, and prepare for their missions to the lunar surface.
Before the Artemis IV mission structure was finalized, NASA engineers needed to design and test the new payload adapter.
“With SLS, there’s an intent to have as much commonality between flights as possible,” says Brent Gaddes, Lead for the Orion Stage Adapter and Payload Adapter in the SLS Spacecraft/Payload Integration & Evolution Office at NASA Marshall.
However, with those payloads changing typically every flight, the connecting payload adapter must change as well.
“We knew there needed to be a lot of flexibility to the payload adapter, and that we needed to be able to respond quickly in-house once the payloads were finalized,” says Gaddes.
Working alongside the robots, NASA’s next generation of engineers are learning from experts with decades of manufacturing expertise as they prepare the metal honeycomb structure substrate. During production, the fingerprints of the engineers are imprinted where metal meets composite. Even after the finishing touches are applied, the right light at the right angle reveals the harmless prints of the adapter’s makers as it launches payloads on SLS that will enable countless discoveries.NASA/Samuel Lott A Flexible Approach
The required flexibility was not going to be satisfied with a one-size-fits-all approach, according to Gaddes.
Since different size payload adapters could be needed, Marshall is using a flexible approach to assemble the payload adapter that eliminates the need for heavy and expensive tooling used to hold the parts in place during assembly. A computer model of each completed part is created using a process called structured light scanning. The computer model provides the precise locations where holes need to be drilled to hold the parts together so that the completed payload adapter will be exactly the right size.
“Structured light has helped us reduce costs and increase flexibility on the payload adapter and allows us to pivot,” says Gaddes. “If the call came down to build a cargo version of SLS to launch 40 metric tons, for example, we can use our same tooling with the structured light approach to adapt to different sizes, whether that’s for an adapter with a larger diameter that’s shorter, or one with a smaller diameter that’s longer. It’s faster and cheaper.”
NASA Marshall engineers use an automated placement robot to manufacture eight lightweight composite panels from a graphite epoxy material. The robot performs fast, accurate lamination following preprogrammed paths, its high speed and precision resulting in lower cost and significantly faster production than other manufacturing methods.
At NASA Marshall, an engineering development unit of the payload has been successfully tested which demonstrated that it can handle up to three times the expected load. Another test version currently in development, called the qualification unit, will also be tested to NASA standards for composite structures to ensure that the flight unit will perform as expected.
“The payload adapter is shaped like a cone, and historically, most of the development work on structures like this has been on cylinders, so that’s one of the many reasons why testing it is so important,” says Gaddes. “NASA will test as high a load as possible to learn what produces structural failure. Any information we learn here will feed directly into the body of information NASA has pulled together over the years on how to analyze structures like this, and of course that’s something that’s shared with industry as well. It’s a win for everybody.”
With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.
