The NASA DC-8 Retires: Reflections on its Contributions to Earth System Science
Introduction
Since 1987, a highly modified McDonnell Douglas DC-8 aircraft has been a workhorse in NASA’s Airborne Science Program (ASP)—see Photo 1. The aircraft, located at NASA’s Armstrong Flight Research Center (AFRC) in California, flew countless missions as a science laboratory, producing science data that supports projects serving the world’s scientific community, particularly the NASA Earth science community. NASA recently decided to retire the venerable DC-8 aircraft, which made its last science flight in April 2024. The DC-8 is being replaced with a similarly refurbished Boeing 777 aircraft, which will be even more capable than the DC-8.

Workshop Overview
The NASA History Office and NASA Earth Science Division cohosted a workshop, titled “Contributions of the DC-8 to Earth System Science at NASA,” on October 24–25, 2024 at the Mary W. Jackson NASA Headquarters (HQ) Building in Washington, DC – see Photo 2.
The agenda included not just the DC-8’s contributions to Earth Science at NASA, but also its role supporting the Aeronautics Research Mission Directorate and work in space science. Many DC-8 veterans – including several who are now retired – attended the event in person or online. The program consisted of six panels and roundtables, each calling attention to a unique aspect of the DC-8 story.

The Tale of the NASA DC-8
The article follows the outline of the workshop that places the DC-8 in the context of the overall history of NASA aircraft observations, science campaigns, community, and international collaboration, education and outreach activities.
A History in Context: the DC-8 and NASA’s Airborne Science Program
NASA’s involvement in airborne science extends to the agency’s inception. The National Aeronautics and Space Act of 1958 states that NASA’s first objective shall be “the expansion of human knowledge of phenomena in the atmosphere and space.” Subsequent legislation expanded NASA’s role in atmospheric and Earth system science. To fulfill this objective, NASA maintains a fleet of airborne platforms through ASP – see Figure –to study the environment, develop new technologies, verify satellite data, and monitor space vehicle activity.
Figure. The DC-8 was but one aircraft is NASA’s sizeable Airborne Science Fleet – which is maintained and operated by ASP. Note that in addition to a variety of piloted aircraft operating at different altitudes shown in this drawing, NASA also operates uncrewed aircraft systems and even uses kites to conduct Earth observations. Figure credit: NASA Science Suborbital Platforms, NASA’s Goddard Space Flight Center, Science Support Office NASA operated two large flying laboratories prior to the DC-8 Airborne Science Laboratory. Both aircraft were converted Convair (CV) 990s. Regrettably, both aircraft succumbed to catastrophic accidents. The first, known as Galileo, collided with a U.S. Navy P-3 Orion near Moffett Field, CA, in April 1973, killing 11 NASA personnel. Its replacement, Galileo II, crashed on takeoff at March Air Force Base in July 1985. While there were no fatalities in the second accident, the ensuing fire consumed the aircraft and its instruments. The loss of Galileo II left a gaping hole in NASA’s ability to conduct essential scientific and engineering research.
In January 1986, after months of bureaucratic scrambling, NASA finalized the purchase of former commercial airliner (DC-8-72) for $24 million, which included costs to modify the aircraft to carry a science payload and crew. The modified DC-8 Airborne Science Laboratory—shown in Photo 2— arrived at NASA Ames Research Center during the Summer of 1987.
Overview Presentations on Airborne Science
Jack Kaye [NASA Headquarters—Associate Director for Research of the Earth Science Division] gave the meeting’s opening remarks, where he placed the DC-8’s activities in a larger perspective. He noted that one of the features that makes airborne science so unique at NASA is the combination of platforms, sensors, systems, people, and opportunities. The DC-8 was able to carry a large number of people as well as instruments to carry out long-range operations under diverse conditions.
“[The DC-8 offered] a really versatile, flexible platform that’s allowed for lots of science,” said Kaye.
Later in the meeting, Karen St. Germain [NASA Headquarters—Director of the Earth Science Division] built upon Kaye’s comments. She noted that while NASA’s satellite missions receive most of the public’s attention, airborne science is an essential part of the NASA mission.
“This is the grassroots of science,” she stressed. “It’s where a lot of the great ideas are born. It’s where a lot of the fledgling sensor technologies are demonstrated.”
First Flight for the DC-8
NASA routinely conducts field campaigns – where ground observations are timed and coordinated with aircraft flights (often at more than one altitude) and with satellite overpasses to gain a comprehensive (multilayered, multiscale) picture of the atmosphere over a certain area. A more detailed account of two NASA field campaigns from the 1980s and 1990s, and their follow-up missions, is available in an archived article: see “Reflections on FIFE and BOREAS: Historical Perspective and Meeting Summary” [The Earth Observer, January–February 2017, 29:1, 6–23]. The article illustrates scaled observations as they were conducted during FIFE and BOREAS.
Researchers first used the DC-8 Airborne Science Laboratory on a high-profile interagency field campaign – Antarctic Airborne Ozone Expedition (AAOE), the first airborne experiment to study the chemistry and dynamics of the Antarctic ozone hole. The scientific data collected during AAOE produced unequivocable evidence that human-made chemicals were involved in the destruction of ozone over the Antarctic. This data served as a major impetus toward the enactment of amendments to the Montreal Protocol, which banned the manufacture of chlorofluorocarbons.
Estelle Condon [NASA’s Ames Research Center (ARC), emeritus] was a program manager for AAOE. During the meeting, she shared her memories of the hectic days leading up to the DC-8’s first mission.
“There was an enormous task in front of [the aircraft team] – just a huge task – to get all the relay racks, all the wiring, all the ports for the windows designed and built so that when the scientists finally came, all that instrumentation could actually be put on the aircraft,” said Condon. She added that the ARC staff worked day and night and every weekend to make the plane ready.
“It’s a miracle that they were able to put everything together and get it to the tip of South America in time for the mission,” she said.
Other Noteworthy Field Campaigns Involving the DC-8
The DC-8 would go on to be used in many other field campaigns throughout its 37-year history
and was central to several of NASA’s research disciplines. For example, Michael Kurylo [NASA Headquarters—Atmospheric Composition Program Scientist] was the manager of NASA’s Upper Atmosphere Research Program, where he developed, promoted, and implemented an extramural research program in stratospheric and upper tropospheric composition and directed its advanced planning at a national and international level. Kurylo summarized the DC-8’s many flights to study stratospheric chemistry beyond the AAOE missions.
Kurylo also discussed the DC-8’s role in tropospheric chemistry investigations, especially through the many field campaigns that were conducted as part of the Global Troposphere Experiment (GTE). He also touched on the culture of NASA airborne science and the dynamic that existed between scientists and those who operated and maintained the aircraft. “The scientists were always referred to [by NASA pilots and groundcrew] as ‘coneheads’…. Too much college, not enough high school,” Kurylo explained. But he and his colleagues have such fond memories of their time spent working together onboard the DC-8.
James Crawford [NASA’s Langley Research Center], a project scientist for many of the GTE campaigns, explained that from 1983–2001 16 GTE aircraft-based missions, each with its own name and location, took place. Each mission collected a rich set of data records of atmospheric observations and on many occasions the data were used as baselines for subsequent campaigns. The DC-8 was one of several NASA aircraft involved, the others being the Corvair-990, Electra, and P-3B.
Joshua Schwarz [NOAA’s Chemical Sciencc Laboratory] discussed the airplane’s role in global atmospheric monitoring. He recall thinking, after his first experience with the DC-8 that this flying airborne laboratory, “…was going to make things possible that wouldn’t otherwise be possible,” Schwarz concluded after his first encounter with the DC-8.
Other workshop participants went on to describe how – for nearly four decades – investigators used data collected by instruments on the DC-8 to conduct research and write papers on important scientific and engineering topics.
The People Behind the Aircraft: The DC-8 Community
The DC-8 was a large and durable aircraft capable of long-range flights, which made it ideal for conducting scientific research. Around these research efforts a strong community emerged. Over three decades, the DC-8 accommodated many investigators from NASA, interagency offices, U.S. universities, and international organizations on extended global missions. Agency officials also moved the DC-8 base of operations several times between 1986 and 2024, thereby demanding tremendous cross-center cooperation.
“Looking around the room, it’s clear that what brought us together [for the workshop] is more than just an aircraft,” said Nickelle Reid [NASA’s Armstrong Flight Research Center]. “It’s been a shared commitment, decades of passion and dedication from scientists, yes, but also mechanics, technicians, integration engineers, project managers, mission planners, operations engineers, flight engineers, mission directors, mission managers, logistics technicians and, of course, pilots. This village of people has been the beating heart of the DC-8 program.”
This DC-8 community was well represented at this workshop and played a key role in its success.
The DC-8 as a Means of International Engagement
The DC-8 community expanded beyond the U.S., opening unique opportunities for international engagement. The campaigns of the DC-8 Airborne Science Laboratory routinely involved foreign students, institutions, and governments. For example, the Korea–U.S. Air Quality (KORUS-AQ) campaign, an international cooperative air quality field study in Korea, took place in 2016. For more information about this campaign, see the archived Earth Observer article, “Flying in the ‘Gap’ Between Earth and Space: NASA’s Airborne Science Program” [The Earth Observer, September–October 2022, 32:5, 4–14].
Yunling Lou [NASA/Jet Propulsion Laboratory] spoke to the workshop audience about the value of international collaboration.
“I think [international collaboration] really helped – not just doing the collaboration [to accomplish a specific mission] but doing the training, the capacity building in these countries to build the community of global scientists and engineers,” said Lou.
Trina Dryal [LaRC—Deputy Director] continued that the DC-8 and NASA’s other airborne assets are more than just science laboratories.
“[They] are opportunities for science, diplomacy, international collaboration, cross learning, educational inspiration, and goodwill,” said Dryal—see Photo 3.

Closer to home, the flying scientific laboratory affected the lives of many U.S. students and early career professionals. NASA’s Student Airborne Research Program (SARP), is an eight-week summer internship for rising-senior undergraduates that takes place annually on the East and West coasts of the U.S – see Photo 4. During the program, students gain hands-on experience conducting all aspects of a scientific campaign. They conduct field research, analyze the data, and gain access to one or more of NASA’s ASP flying science laboratories. Since 2009, this program alone has provided hands on experience in conducting NASA Earth science research to XXXX students.
Berry Lefer [NASA Headquarters—Tropospheric Composition Program Manager] pointed out that SARP helped to integrate American students into DC-8 scientific missions.
“I want to make sure the NASA historians understand that the DC-8 is the premier flying laboratory on the planet, bar none,” said Lefer. “You’ve seen over the whole three-decade life of the DC-8 that education and outreach, student involvement has been a hallmark of the DC-8 [program].”
Yaitza Luna-Cruz [NASA Headquarters—Program Executive] was one among several SARP alumni who delivered testimony on the impact of the SARP program at the workshop.
“SARP unleashed my potential in ways that I cannot even describe,” said Luna-Cruz. “You never know what a single opportunity could do to shape the career of a student or early career researcher.
Luna-Cruz hopes these efforts continue with the coming of NASA’s new Boeing 777 airborne laboratory.

The DC-8 Airborne Science Laboratory flew its last science flight during the international Airborne and Satellite Investigation of Asian Air Quality mission (ASIA-AQ) in April 2024. Since its final flight, the aircraft has been retired to Idaho State University (ISU). Today, students in ISU’s aircraft maintenance program work on the airplane to develop real-world technical skills – continuing the DC-8’s mission as an educational platform. According to Gerald Anhorn [ISU—Dean of College of Technology], ISU students have a unique opportuning to gain experience working on a legendary research aircraft.
“Our students have that opportunity because of [NASA’s] donation” to the school, said Auborn.
Conclusion: Flying Toward the Future – From DC-8 to Boeing 777
While the DC-8 is retiring from active service, airborne observations continue to be a vital part of NASA’s mission. The agency recently acquired a Boeing 777and will modify it to support its ongoing airborne scientific research efforts. This new addition expands beyond the capacity of the DC-8 by allowing for even longer flights with larger payloads and more researchers to gather data. Several members of the Boeing 777 team from NASA’s Langley Research Center (LaRC) attended the workshop.
“I mentioned I was in charge of the ‘replacement’ for the DC-8,” said Martin Nowicki [LaRC—Boeing 777 Lead]. “Over the last two days, here, it’s become pretty apparent that there’s no ‘replacing’ the DC-8. It’s carved out its own place in history. It’s just done so much.”
Nowicki looks forward to working with workshop participants to identify useful lessons of the past for future operators. He concluded that the Boeing 777 will carry the legacy of the DC-8 and continue with capturing the amazing science of ASP.

On March 6, 1985, NASA’s newest space shuttle, Atlantis, made its public debut during a rollout ceremony at the Rockwell International manufacturing plant in Palmdale, California. Under construction for three years, Atlantis joined NASA’s other three space-worthy orbiters, Columbia, Challenger, and Discovery, and atmospheric test vehicle Enterprise. Officials from NASA, Rockwell, and other organizations attended the rollout ceremony. By the time NASA retired Atlantis in 2011, it had flown 33 missions in a career spanning 26 years and flying many types of missions envisioned for the space shuttle. The Visitor Center at NASA’s Kennedy Space Center in Florida has Atlantis on display.

On Jan. 25, 1979, NASA announced the names of the first four space-worthy orbiters – Columbia, Challenger, Discovery, and Atlantis. Like the other vehicles, NASA named Atlantis after an historical vessel of discovery and exploration – the Woods Hole Oceanographic Institute’s two-masted research ship Atlantis that operated from 1930 to 1966. On Jan. 29, NASA signed the contract with Rockwell International of Downey, California, to build and deliver Atlantis. Construction began in March 1980 and finished in April 1984. Nearly identical to Discovery but with the addition of hardware to support the cryogenic Centaur upper stage then planned to deploy planetary spacecraft in 1986, plans shelved following the Challenger accident. After a year of testing, workers prepared Atlantis for its public debut.

Three days after the rollout ceremony, workers trucked Atlantis 36 miles overland to NASA’s Dryden, now Armstrong, Flight Research Center at Edwards Air Force Base in California’s Mojave Desert, for final preparations for its cross-country ferry flight. In the Mate Demate Device, workers placed Atlantis atop the Shuttle Carrier Aircraft, a modified Boeing 747, to begin the ferry flight. The duo left Edwards on April 12, the fourth anniversary of the first space shuttle flight. Following an overnight stop at Houston’s Ellington Air Force Base, now Ellington Field, Atlantis arrived at NASA’s Kennedy Space Center in Florida on April 13.

The entire stack rolled out to Launch Pad 39A on Aug. 30 in preparation for the planned Oct. 3 launch of the STS-51J mission. As with any new orbiter, on Sept. 13 NASA conducted a 20-second Flight Readiness Firing of Atlantis’ three main engines. On Sept. 16, the five-person crew participated in a countdown demonstration test, leading to an on time Oct. 3 launch. Atlantis had joined the shuttle fleet and begun its first mission to space.

Over the course of its 33 missions spanning more than 26 years, Atlantis flew virtually every type of mission envisioned for the space shuttle, including government and commercial satellite deployments, deploying spacecraft to visit interplanetary destinations, supporting scientific missions, launching and servicing scientific observatories such as the Hubble Space Telescope, performing crew rotations and resupplying the Mir space station, and assembling and maintaining the International Space Station. Atlantis flew the final mission of the shuttle program, STS-135, in July 2011. The following year, NASA transported Atlantis to the Kennedy Visitor Center for public display.

Technicians with ESA (European Space Agency) and Airbus installed the four solar array wings on NASA’s Orion spacecraft for Artemis II on March 3. The solar array wings, attached to the service module, deploy after Orion reaches space to power the spacecraft.
Orion’s service module provides propulsion, thermal control, and electrical power, as well as air and water for the crew during their mission around the Moon.
Each solar array wing has 15,000 solar cells to convert sunlight to electricity and is nearly 23 feet in length when fully deployed. In space, the arrays can turn on two axes to remain aligned with the Sun.
Artemis II is the first crewed mission under NASA’s Artemis campaign. Through Artemis, the agency will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.
