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.”

Before Apollo astronauts set foot upon the Moon, much remained unknown about the lunar surface. While most scientists believed the Moon had a solid surface that would support astronauts and their landing craft, a few believed a deep layer of dust covered it that would swallow any visitors. Until 1964, no closeup photographs of the lunar surface existed, only those obtained by Earth-based telescopes.
NASA’s Jet Propulsion Laboratory in Pasadena, California, managed the Ranger program, a series of spacecraft designed to return closeup images before impacting on the Moon’s surface. Ranger 7 first accomplished that goal in July 1964. On Feb. 17, 1965, its successor Ranger 8 launched toward the Moon, and three days later returned images of the Moon. The mission’s success helped the country meet President John F. Kennedy’s goal of a human Moon landing before the end of the decade.
Schematic diagram of the Ranger 8 spacecraft, showing its major components. NASA/JPL The television system aboard Ranger 8 showing its six cameras.NASA/JPL. Launch of Ranger 8. NASA. Ranger 8 lifted off from Cape Kennedy, now Cape Canaveral, Florida, on Feb. 17, 1965. The Atlas-Agena rocket first placed the spacecraft into Earth orbit before sending it on a lunar trajectory. The next day, the spacecraft carried out a mid-course correction, and on Feb. 20, Ranger 8 reached the Moon. The spacecraft’s six cameras turned on as planned, about eight minutes earlier than its predecessor to obtain images comparable in resolution to ground-based photographs for calibration purposes. Ranger 8 took its first photograph at an altitude of 1,560 miles, and during its final 23 minutes of flight, the spacecraft sent back 7,137 images of the lunar surface. The last image, taken at an altitude of 1,600 feet and 0.28 seconds before Ranger 8 impacted at 1.67 miles per second, had a resolution of about five feet. The spacecraft impacted 16 miles from its intended target in the Sea of Tranquility, ending a flight of 248,900 miles. Scientists had an interest in this area of the Moon as a possible landing zone for a future human landing, and indeed Apollo 11 landed 44 miles southeast of the Ranger 8 impact site in July 1969.

Ranger 8’s final images, taken at an altitude as low as 1,600 feet. NASA/JPL. One more Ranger mission followed, Ranger 9, in March 1965. Television networks broadcast Ranger 9’s images of the Alphonsus crater and the surrounding area “live” as the spacecraft approached its impact site in the crater – letting millions of Americans see the Moon up-close as it happened. Based on the photographs returned by the last three Rangers, scientists felt confident to move on to the next phase of robotic lunar exploration, the Surveyor series of soft landers. The Ranger photographs provided confidence that the lunar surface could support a soft-landing and that the Sea of Tranquility presented a good site for the first human landing. A little more than four years after the final Ranger images, Apollo 11 landed the first humans on the Moon.

The impacts of the Ranger probes left visible craters on the lunar surface, later photographed by orbiting spacecraft. Lunar Orbiter 2 and Apollo 16 both imaged the Ranger 8 impact site at relatively low resolution in 1966 and 1972, respectively. The Lunar Reconnaissance Orbiter imaged the crash site in greater detail in 2012.

With two months to go before flight, the Apollo 13 prime crew of James Lovell, Thomas Mattingly, Fred Haise, and backups John Young, John Swigert, and Charles Duke continued to train for the 10-day mission planned to land in the Fra Mauro highlands region of the Moon. Engineers continued to prepare the Saturn V rocket and spacecraft at the launch pad for the April 11, 1970, liftoff and completed the Flight Readiness Test of the vehicle. All six astronauts spent many hours in flight simulators training while the Moon walkers practiced landing the Lunar Module and rehearsed their planned Moon walks. The crew for the next Moon landing mission, Apollo 14, participated in a geology field trip as part of their training for the flight then planned for October 1970. Meanwhile, NASA released Apollo 12 lunar samples to scientists and the Apollo 12 crew set off on a Presidential world goodwill tour.
At NASA’s Kennedy Space Center in Florida, engineers completed the Flight Readiness Test of the Apollo 13 Saturn V on Feb. 26. The test ensured that all systems are flight ready and compatible with ground support equipment, and the astronauts simulated portions of the countdown and powered flight. Successful completion of the readiness test cleared the way for a countdown dress rehearsal at the end of March.

NASA Fred Haise prepares for a flight at the Lunar Landing Research Facility. NASA One of the greatest challenges astronauts faced during a lunar mission entailed completing a safe landing on the lunar surface. In addition to time spent in simulators, Apollo mission commanders and their backups trained for the final few hundred feet of the descent using the Lunar Landing Training Vehicle at Ellington Air Force Base near the Manned Spacecraft Center, now NASA’s Johnson Space Center, in Houston. Bell Aerosystems of Buffalo, New York, built the trainer for NASA to simulate the flying characteristics of the Lunar Module. Lovell and Young completed several flights in February 1970. Due to scheduling constraints with the trainer, lunar module pilots trained for their role in the landing using the Lunar Landing Research Facility at NASA’s Langley Research Center in Hampton, Virginia. Haise and Duke completed training sessions at the Langley facility in February.

NASA The astronauts trained for moonwalks with parabolic flights aboard NASA’s KC-135 aircraft that simulated the low lunar gravity, practicing their ladder descent to the surface. On the ground, they rehearsed the moonwalks, setting up the American flag and the large S-band communications antenna, and collecting lunar samples. Engineers improved their spacesuits to make the expected longer spacewalks more comfortable for the crew members by installing eight-ounce bags of water inside the helmets for hydration.

NASA During their 35 hours on the Moon’s surface, Lovell and Haise planned to conduct two four-hour spacewalks to set up the Apollo Lunar Surface Experiment Package (ALSEP), a suite of four investigations designed to collect data about the lunar environment after the astronauts’ departure, and to conduct geologic explorations of the landing site. The four experiments included the:
Charged Particle Lunar Environment Experiment designed to measure the flexes of charged particles Cold Cathode Gauge Experiment designed to measure the pressure of the lunar atmosphere Heat Flow Experiment designed to make thermal measurements of the lunar subsurface Passive Seismic Experiment designed to measure any moonquakes, either naturally occurring or caused by artificial means As an additional investigation, the astronauts planned to deploy and retrieve the Solar Wind Composition experiment, a sheet of aluminum foil to collect particles from the solar wind for analysis by scientists back on Earth after about 20 hours of exposure on the lunar surface.

NASA With one lunar mission just two months away, NASA continued preparations for the following flight, Apollo 14, then scheduled for October 1970 with a landing targeted for the Littrow region of the Moon, an area scientists believed to be of volcanic origin. Apollo 14 astronauts Alan Shepard, Stuart Roosa, and Edgar Mitchell and their backups Eugene Cernan, Ronald Evans, and Joe Engle learned spacecraft systems in the simulators. Accompanied by a team of geologists led by Richard Jahns, Shepard, Mitchell, Cernan, and Engle participated in a geology expedition to the Pinacate Mountain Range in northern Mexico Feb. 14-18, 1970. The astronauts practiced using the Modular Equipment Transporter, a two-wheeled conveyance to transport tools and samples on the lunar surface.
Mail out of the Apollo 12 lunar samples. Apollo 12 astronauts Charles Conrad, left, Richard Gordon, and Alan Bean ride in a motorcade in Lima, Peru.NASA On Feb. 13, 1970, NASA began releasing Apollo 12 lunar samples to 139 U.S. and 54 international scientists in 16 countries, a total of 28.6 pounds of material. On Feb. 16, Apollo 12 astronauts Charles Conrad, Richard Gordon, and Alan Bean, accompanied by their wives and NASA and State Department officials, departed Houston’s Ellington Air Force Base for their 38-day Bullseye Presidential Goodwill World Tour. They first traveled to Latin America, making stops in Venezuela, Peru, Chile, and Panama before continuing on to Europe, Africa, and Asia.
The groundbreaking science and discoveries made during Apollo missions has pushed NASA to explore the Moon more than ever before through the Artemis program. Apollo astronauts set up mirror arrays, or “retroreflectors,” on the Moon to accurately reflect laser light beamed at them from Earth with minimal scattering or diffusion. Retroreflectors are mirrors that reflect the incoming light back in the same incoming direction. Calculating the time required for the beams to bounce back allowed scientists to precisely measure the Moon’s shape and distance from Earth, both of which are directly affected by Earth’s gravitational pull. More than 50 years later, on the cusp of NASA’s crewed Artemis missions to the Moon, lunar research still leverages data from those Apollo-era retroreflectors.

Official portrait of NASA Associate Administrator Jim Free, taken on Nov. 22, 2024, at the agency’s headquarters in Washington.Credit: NASA/Bill Ingalls NASA Associate Administrator Jim Free announced Wednesday his retirement, effective Saturday, Feb. 22. 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.
