6 Min Read NASA Marshall Reflects on 65 Years of Ingenuity, Teamwork
NASA’s Marshall Space Flight Center in Huntsville, Alabama, is celebrating its 65-year legacy of ingenuity and service to the U.S. space program – and the expansion of its science, engineering, propulsion, and human spaceflight portfolio with each new decade since the NASA field center opened its doors on July 1, 1960.
What many Americans likely call to mind are the “days of smoke and fire,” said Marshall Director Joseph Pelfrey, referring to the work conducted at Marshall to enable NASA’s launch of the first Mercury-Redstone rocket and the Saturn V which lifted Americans to the Moon, the inaugural space shuttle mission, and the shuttle flights that carried the Hubble Space Telescope, Chandra X-ray Observatory, and elements of the International Space Station to orbit. Most recently, he said they’re likely to recall the thunder of NASA’s SLS (Space Launch System), rising into the sky during Artemis I.
NASA’s Space Launch System, carrying the Orion spacecraft, launches on the Artemis I flight test on Nov. 16, 2022. NASA’s Marshall Space Flight Center in Huntsville, Alabama, led development and oversees all work on the new flagship rocket, building on its storied history of propulsion and launch vehicle design dating back to the Redstone and Saturn rockets. The most powerful rocket ever built, SLS is the backbone of NASA’s Artemis program, set to carry explorers back to the Moon in 2026, help establish a permanent outpost there, and make possible new, crewed journeys to Mars in the years to come.NASA/Bill Ingalls Yet all the other days are equally meaningful, Pelfrey said, highlighting a steady stream of milestones reflecting the work of Marshall civil service employees, contractors, and industry partners through the years – as celebrated in a new “65 Years of Marshall” timeline.
“The total sum of hours, contributed by tens of thousands of men and women across Marshall’s history, is incalculable,” Pelfrey said. “Together they’ve blended legacy with innovation – advancing space exploration and scientific discovery through collaboration, engineering excellence, and technical solutions. They’ve invented and refined technologies that make it possible to safely live and work in space, to explore other worlds, and to help safeguard our own.

“Days of smoke and fire may be the most visible signs, but it’s the months and years of preparation and the weeks of post-launch scientific discovery that mark the true dedication, sacrifice, and monumental achievements of this team.”
Reflecting on Marshall history
Marshall’s primary task in the 1960s was the development and testing of the rockets that carried the first American astronaut to space, and the much larger and more technically complex Saturn rocket series, culminating in the mighty Saturn V, which carried the first human explorers to the Moon’s surface in 1969.
“Test, retest, and then fly – that’s what we did here at the start,” said retired engineer Harry Craft, who was part of the original U.S. Army rocket development team that moved from Fort Bliss, Texas, to Huntsville to begin NASA’s work at Marshall. “And we did it all without benefit of computers, working out the math with slide rules and pads of paper.”
The 138-foot-long first stage of the Saturn V rocket is lowered to the ground following a successful static test firing in fall 1966 at the S-1C test stand at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The Saturn V, developed and managed at Marshall, was a multi-stage, multi-engine launch vehicle that stood taller than the Statue of Liberty and lofted the first Americans to the Moon. Its success helped position Marshall as an aerospace leader in propulsion, space systems, and launch vehicle development.NASA “Those were exciting times,” retired test engineer Parker Counts agreed. He joined Marshall in 1963 to conduct testing of the fully assembled and integrated Saturn first stages. It wasn’t uncommon for work weeks to last 10 hours a day, plus weekend shifts when deadlines were looming.
Counts said Dr. Wernher von Braun, Marshall’s first director, insisted staff in the design and testing organizations be matched with an equal number of engineers in Marshall’s Quality and Reliability Assurance Laboratory.
“That checks-and-balances engineering approach led to mission success for all 32 of the Saturn family of rockets,” said Counts, who went on to support numerous other propulsion programs before retiring from NASA in 2003.
“We worked with the best minds and best equipment available, pushing the technology every day to deliver the greatest engineering achievement of the 20th century,” said instrumentation and electronics test engineer Willie Weaver, who worked at Marshall from 1960 to 1988 – and remains a tour guide at its visitor center, the U.S. Space & Rocket Center.

The 1970s at Marshall were a period of transition and expanded scientific study, as NASA ended the Apollo Program and launched the next phase of space exploration. Marshall provided critical work on the first U.S. space station, Skylab, and led propulsion element development and testing for NASA’s Space Shuttle Program.
Marshall retiree Jim Odom, a founding engineer who got his start launching NASA satellites in the run-up to Apollo, managed the Space Shuttle External Tank project. The role called for weekly trips to NASA’s Michoud Assembly Facility in New Orleans, which has been managed by Marshall since NASA acquired the government facility in 1961. The shuttle external tanks were manufactured in the same bays there where NASA and its contractors built the Saturn rockets.
This photograph shows the liquid hydrogen tank and liquid oxygen tank for the Space Shuttle external tank (ET) being assembled in the weld assembly area of the Michoud Assembly Facility (MAF). The ET provides liquid hydrogen and liquid oxygen to the Shuttle’s three main engines during the first eight 8.5 minutes of flight. At 154-feet long and more than 27-feet in diameter, the ET is the largest component of the Space Shuttle, the structural backbone of the entire Shuttle system, and the only part of the vehicle that is not reusable. The ET is manufactured at the Michoud Assembly Facility near New Orleans, Louisiana, by the Martin Marietta Corporation under management of the Marshall Space Flight Center.NASA “We didn’t have cellphones or telecon capabilities yet,” Odom recalled. “I probably spent more time with the pilot of the twin-engine plane in those days than I did with my wife.”
Marshall’s shuttle propulsion leadership led to the successful STS-1 mission in 1981, launching an era of orbital science exemplified by NASA’s Spacelab program.
“Spacelab demonstrated that NASA could continue to achieve things no one had ever done before,” said Craft, who served as mission manager for Spacelab 1 in 1983 – a highlight of his 40-year NASA career. “That combination of science, engineering, and global partnership helped shape our goals in space ever since.”
Engineers in the X-ray Calibration Facility at NASA’s Marshall Space Flight Center in Huntsville, Alabama, work to integrate elements of the Chandra X-ray Observatory in this March 1997 photo. Chandra was lifted to orbit by space shuttle Columbia on July 23, 1999, the culmination of two decades of telescope optics, mirror, and spacecraft development and testing at Marshall. In the quarter century since, Chandra has delivered nearly 25,000 detailed observations of neutron stars, supernova remnants, black holes, and other high-energy objects, some as far as 13 billion light-years distant. Marshall continues to manage the program for NASA. NASA Bookended by the successful Hubble and Chandra launches, the 1990s also saw Marshall deliver the first U.S. module for the International Space Station, signaling a transformative new era of human spaceflight.
Odom, who retired in 1989 as associate administrator for the space station at NASA Headquarters, reflects on his three-decade agency career with pride.
“It was a great experience, start to finish, working with the teams in Huntsville and New Orleans and our partners nationwide and around the globe, meeting each new challenge, solving the practical, day-to-day engineering and technology problems we only studied about in college,” he said.
Shrouded for transport, a 45-foot segment of the International Space Station’s “backbone” truss rolls out of test facilities at NASA’s Marshall Space Flight Center in Huntsville, Alabama, in July 2000, ready to be flown to the Kennedy Space Center in Florida for launch. Marshall played a key role in the development, testing, and delivery of the truss and other critical space station modules and structural elements, as well as the station’s air and water recycling systems and science payload hardware. Marshall’s Payload Operations Integration Center also continues to lead round-the-clock space station science. NASA That focus on human spaceflight solutions continued into the 21st century. Marshall delivered additional space station elements and science hardware, refined its air and water recycling systems, and led round-the-clock science from the Payload Operations Integration Center. Marshall scientists also managed the Gravity Probe Band Hinode missions and launched NASA’s SERVIR geospatial observation system. Once primary space stationconstruction – and the 40-year shuttle program – concluded in the 2010s, Marshall took on oversight of NASA’s Space Launch System, led James Webb Space Telescope mirror testing, and delivered the orbiting Imaging X-ray Polarimetry Explorer.
As the 2020s continue, Marshall meets each new challenge with enthusiasm and expertise, preparing for the highly anticipated Artemis II crewed launch and a host of new science and discovery missions – and buoyed by strong industry partners and by the Huntsville community, which takes pride in being home to “Rocket City USA.”
“Humanity is on an upward, outward trajectory,” Pelfrey said. “And day after day, year after year, Marshall is setting the course to explore beyond tomorrow’s horizon.”

Connected Learning Ecosystems: Educators Learning and Growing Together
On August 19-20, 53 educators from a diverse set of learning contexts (libraries, K-12 classrooms, 4-H afterschool clubs, outdoor education centers, and more) gathered in Orono, Maine for the Learning Ecosystems Northeast (LENE) biannual Connect, Reflect, & Plan Connected Learning Ecosystems (CLEs) Gathering. These gatherings are meant to foster meaningful connections and collaborations and shared knowledge and confidence building amongst educators within the LENE network.
NASA Science Activation’s Learning Ecosystems Northeast (LENE) is a network of education partners across the Northeastern United States, led by the Gulf of Maine Research Institute. These partners are dedicated to creating and linking communities of in and out of school educators, Connected Learning Ecosystems (CLEs), who are committed to empowering the next generation of climate stewards.
The focus of this gathering was to provide educators the time, experiences, connections, and space to explore ways they can prepare the youth and communities they work with to build resilience in the face of climate change. Educators participated in sessions around local asset mapping, climate mental health, positive youth development, building STEM skills through games and fieldwork, and planning forward around coastal flooding and sea level rise. Each session was followed by time to debrief, reflect, and plan both in their regional CLEs as well as with statewide partners. The value of NASA assets and connection to local issues was woven throughout many experiences during this gathering. LENE’s CLE Resource Drive has a growing list of phenomena-based NASA assets that has been curated based on the interests of their network over time. The Global Learning and Observations to Benefit the Environment (GLOBE) program’s GLOBE Observer tree height app was part of the Ash Protection community science protocol and many NASA assets enhance the educator-guided planning forward experience guide that youth practice the difficult, real-life conversations about the
consequences of sea level rise as they think about ways they can plan for a resilient future in the face of rising seas and coastal flooding.
Sara King from the Rural Aspirations Project (Hancock/Midcoast CLE) had this to say: “Before I first joined the CLE, I viewed STEM professionals to be separate from myself for the most part because I did not feel very confident in my abilities in all parts of STEM. I feel more comfortable with data and technology, engineering, and science practices now.”
One educator said that their highlight from the gathering was, “[o]pportunities to meet with other teachers and educators and librarians to share ideas about how we can pool our resources and reach more students.” These educators left with draft learning projects ready for refinement and review, renewed dedication and motivation for the school year, and new perspectives to lead them into continued conversations and partnership with their CLE peers as they meet throughout the year.

5 Min Read 25 Years On, Chandra Highlights Legacy of NASA Engineering Ingenuity
By Rick Smith
“The art of aerospace engineering is a matter of seeing around corners,” said NASA thermal analyst Jodi Turk. In the case of NASA’s Chandra X-ray Observatory, marking its 25th anniversary in space this year, some of those corners proved to be as far as 80,000 miles away and a quarter-century in the future.
Turk is part of a dedicated team of engineers, designers, test technicians, and analysts at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Together with partners outside and across the agency, including the Chandra Operations Control Center in Burlington, Massachusetts, they keep the spacecraft flying, enabling Chandra’s ongoing studies of black holes, supernovae, dark matter, and more – and deepening our understanding of the origin and evolution of the cosmos.
Engineers in the X-ray Calibration Facility – now the world-class X-ray & Cryogenic Facility – at NASA’s Marshall Space Flight Center in Huntsville, Alabama, integrate the Chandra X-ray Observatory’s High Resolution Camera with the mirror assembly inside a 24-foot-diameter vacuum chamber, in this photo taken March 16, 1997. Chandra was launched July 23, 1999, aboard space shuttle Columbia.NASA “Everything Chandra has shown us over the last 25 years – the formation of galaxies and super star clusters, the behavior and evolution of supermassive black holes, proof of dark matter and gravitational wave events, the viability of habitable exoplanets – has been fascinating,” said retired NASA astrophysicist Martin Weisskopf, who led Chandra scientific development at Marshall beginning in the late 1970s. “Chandra has opened new windows in astrophysics that we’d hardly begun to imagine in the years prior to launch.”
Following extensive development and testing by a contract team managed and led by Marshall, Chandra was lifted to space aboard the space shuttle Columbia on July 23, 1999. Marshall has continued to manage the program for NASA ever since.
“How much technology from 1999 is still in use today?” said Chandra researcher Douglas Swartz. “We don’t use the same camera equipment, computers, or phones from that era. But one technological success – Chandra – is still going strong, and still so powerful that it can read a stop sign from 12 miles away.”
That lasting value is no accident. During early concept development, Chandra – known prior to launch as the Advanced X-ray Astrophysics Facility – was intended to be a 15-year, serviceable mission like that of NASA’s Hubble Space Telescope, enabling periodic upgrades by visiting astronauts.
But in the early 1990s, as NASA laid plans to build the International Space Station in orbit, the new X-ray observatory’s budget was revised. A new, elliptical orbit would carry Chandra a third of the way to the Moon, or roughly 80,000 miles from Earth at apogee. That meant a shorter mission life – five years – and no periodic servicing.
The Chandra X-Ray Observatory, the longest cargo ever carried to space aboard the space shuttle, seen in Columbia’s payload bay prior to being tilted upward for release and deployment on July 23, 1999.NASA The engineering design team at Marshall, its contractors, and the mission support team at the Smithsonian Astrophysical Observatory revised their plan, minimizing the impact to Chandra’s science. In doing so, they enabled a long-running science mission so successful that it would capture the imagination of the nation and lead NASA to extend its duration past that initial five-year period.
“There was a lot of excitement and a lot of challenges – but we met them and conquered them,” said Marshall project engineer David Hood, who joined the Chandra development effort in 1988.
“The field of high-powered X-ray astronomy was still so relatively young, it wasn’t just a matter of building a revolutionary observatory,” Weisskopf said. “First, we had to build the tools necessary to test, analyze, and refine the hardware.”
Marshall renovated and expanded its X-ray Calibration Facility – now known as the X-ray & Cryogenic Facility – to calibrate Chandra’s instruments and conduct space-like environment testing of sensitive hardware. That work would, years later, pave the way for Marshall testing of advanced mirror optics for NASA’s James Webb Space Telescope.
On July 23, 1999, the Chandra X-Ray Observatory is released from space shuttle Columbia’s payload bay. Twenty-five years later, Chandra continues to make valuable discoveries about high-energy sources and phenomena across the universe.NASA “Marshall has a proven history of designing for long-term excellence and extending our lifespan margins,” Turk said. “Our missions often tend to last well past their end date.”
Chandra is a case in point. The team has automated some of Chandra’s operations for efficiency. They also closely monitor key elements of the spacecraft, such as its thermal protection system, which have degraded as anticipated over time, due to the punishing effects of the space environment.
“Chandra’s still a workhorse, but one that needs gentler handling,” Turk said. The team met that challenge by meticulously modeling and tracking Chandra’s position and behavior in orbit and paying close attention to radiation, changes in momentum, and other obstacles. They have also employed creative approaches, making use of data from sensors on the spacecraft in new ways.
Acting project manager Andrew Schnell, who leads the Chandra team at Marshall, said the mission’s length means the spacecraft is now overseen by numerous “third-generation engineers” such as Turk. He said they’re just as dedicated and driven as their senior counterparts, who helped deliver Chandra to launch 25 years ago.
An artist’s illustration depicting NASA’s Chandra X-ray Observatory in flight, with a vivid star field behind it. Chandra’s solar panels are deployed and its camera “eye” open on the cosmos.NASA The work also provides a one-of-a-kind teaching opportunity, Turk said. “Troubleshooting Chandra has taught us how to find alternate solutions for everything from an interrupted sensor reading to aging thermocouples, helping us more accurately diagnose issues with other flight hardware and informing design and planning for future missions,” she said.
Well-informed, practically trained engineers and scientists are foundational to productive teams, Hood said – a fact so crucial to Chandra’s success that its project leads and support engineers documented the experience in a paper titled, “Lessons We Learned Designing and Building the Chandra Telescope.”
“Former program manager Fred Wojtalik said it best: ‘Teams win,’” Hood said. “The most important person on any team is the person doing their work to the best of their ability, with enthusiasm and pride. That’s why I’m confident Chandra’s still got some good years ahead of her. Because that foundation has never changed.”
As Chandra turns the corner on its silver anniversary, the team on the ground is ready for whatever fresh challenge comes next.
