1987, a highly modified McDonnell Douglas DC-8 aircraft has been a workhorse in <a href=\"https:\/\/airbornescience.nasa.gov\/\" rel=\"noopener\">NASA\u2019s Airborne Science Program<\/a> (ASP)\u2014see <strong>Photo 1<\/strong>. The aircraft, located at NASA\u2019s Armstrong Flight Research Center (AFRC) in California, flew countless missions as a science laboratory, producing science data that supports projects serving the world\u2019s 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.<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=1440&#038;h=960&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1440\" height=\"960\" src=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=1440&#038;h=960&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"DC8 Photo 1\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=1440&#038;h=960&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1440w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=300&#038;h=200&#038;fit=crop&#038;crop=faces%2Cfocalpoint 300w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=768&#038;h=512&#038;fit=crop&#038;crop=faces%2Cfocalpoint 768w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=1024&#038;h=683&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1024w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=400&#038;h=267&#038;fit=crop&#038;crop=faces%2Cfocalpoint 400w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=600&#038;h=400&#038;fit=crop&#038;crop=faces%2Cfocalpoint 600w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=900&#038;h=600&#038;fit=crop&#038;crop=faces%2Cfocalpoint 900w, https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/earth-observer\/2025\/2025-winter\/2025-dc-8\/DC8-photo1.jpg?w=1200&#038;h=800&#038;fit=crop&#038;crop=faces%2Cfocalpoint 1200w\" sizes=\"auto, (max-width: 1440px) 100vw, 1440px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\">\n<div class=\"hds-caption-text p-sm margin-0\"><strong>Photo 1.<\/strong> NASA\u2019s DC-8 flying laboratory flew Earth science missions for NASA\u2019s.

Both aircraft were converted Convair (CV) 990s. Regrettably, both aircraft succumbed to catastrophic accidents. The first, known as <em>Galileo<\/em>, collided with a U.S. Navy P-3 Orion near Moffett Field, CA, in April 1973, killing 11 NASA personnel. Its replacement, <em>Galileo II<\/em>, 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 <em>Galileo II<\/em> left a gaping hole in NASA\u2019s ability to conduct essential scientific and engineering research.<\/p>\n<p>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\u2014shown in <strong>Photo 2<\/strong>\u2014 arrived at NASA Ames Research Center during the Summer of 1987.<\/p>\n<p><em>Overview Presentations on Airborne Science<\/em><\/p>\n<p><strong>Jack Kaye<\/strong> [NASA Headquarters\u2014<em>Associate Director for Research of the Earth Science Division<\/em>] gave the meeting\u2019s opening remarks, where he placed the DC-8\u2019s 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.<\/p>\n<p>\u201c[The DC-8 offered] a really versatile, flexible platform that\u2019s allowed for lots of science,\u201d said Kaye.<\/p>\n<p>Later in the meeting, <strong>Karen St. Germain<\/strong> [NASA Headquarters\u2014<em>Director of the Earth Science Division<\/em>] built upon Kaye\u2019s comments. She noted that while NASA\u2019s satellite missions receive most of the public\u2019s attention, airborne science is an essential part of the NASA mission.<\/p>\n<p>\u201cThis is the grassroots of science,\u201d she stressed. \u201cIt\u2019s where a lot of the great ideas are born. It\u2019s where a lot of the fledgling sensor technologies are demonstrated.\u201d<\/p>\n<p><em>First Flight for the DC-8<\/em><\/p>\n<p>NASA routinely conducts <em>field campaigns<\/em> \u2013 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 \u201c<a href=\"https:\/\/eospso.nasa.gov\/sites\/default\/files\/eo_pdfs\/Jan-Feb%202017%20color%20508.pdf#page=6\" rel=\"noopener\">Reflections on FIFE and BOREAS: Historical Perspective and Meeting Summary<\/a>\u201d [<em>The Earth Observer<\/em>, January\u2013February 2017, <strong>29:1<\/strong>, 6\u201323]. The article illustrates scaled observations as they were conducted during FIFE and BOREAS.<\/p>\n<p>Researchers first used the DC-8 Airborne Science Laboratory on a high-profile interagency field campaign \u2013 <a href=\"https:\/\/impact.earthdata.nasa.gov\/casei\/campaign\/AAOE\/\" rel=\"noopener\">Antarctic Airborne Ozone Expedition<\/a> (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.<\/p>\n<p><strong>Estelle Condon<\/strong> [NASA\u2019s Ames Research Center (ARC), <em>emeritus<\/em>] was a program manager for AAOE. During the meeting, she shared her memories of the hectic days leading up to the DC-8\u2019s first mission.<\/p>\n<p>\u201cThere was an enormous task in front of [the aircraft team] \u2013 just a huge task \u2013 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,\u201d said Condon. She added that the ARC staff worked day and night and every weekend to make the plane ready.<\/p>\n<p>\u201cIt\u2019s a miracle that they were able to put everything together and get it to the tip of South America in time for the mission,\u201d she said.<\/p>\n<p><em>Other Noteworthy Field Campaigns Involving the DC-8<\/em><\/p>\n<p>The DC-8 would go on to be used in many other field campaigns throughout its 37-year history<\/p>\n<p>and was central to several of NASA\u2019s research disciplines. For example, <strong>Michael Kurylo<\/strong> [NASA Headquarters\u2014<em>Atmospheric Composition Program Scientist<\/em>] was the manager of NASA\u2019s 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\u2019s many flights to study stratospheric chemistry beyond the AAOE missions.<\/p>\n<p>Kurylo also discussed the DC-8\u2019s role in tropospheric chemistry investigations, especially through the many field campaigns that were conducted as part of the <a href=\"https:\/\/www-gte.larc.nasa.gov\/\" rel=\"noopener\">Global Troposphere Experiment<\/a> (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. \u00a0\u201cThe scientists were always referred to [by NASA pilots and groundcrew] as \u2018coneheads\u2019\u2026. Too much college, not enough high school,\u201d Kurylo explained. But he and his colleagues have such fond memories of their time spent working together onboard the DC-8.\u00a0<\/p>\n<p><strong>James Crawford<\/strong> [NASA\u2019s Langley Research Center], a project scientist for many of the GTE campaigns, explained that from 1983\u20132001 <a href=\"https:\/\/www-gte.larc.nasa.gov\/GTE2\/missions\/Aircraft_Based_Missions\/Aircraft_Based_Missions.htm\" rel=\"noopener\">16 GTE aircraft-based missions<\/a>, 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.\u00a0The DC-8 was one of several NASA aircraft involved, the others being the Corvair-990, Electra, and P-3B.<\/p>\n<p><strong>Joshua Schwarz<\/strong> [NOAA\u2019s Chemical Sciencc Laboratory] discussed the airplane\u2019s role in global atmospheric monitoring.\u00a0 He recall thinking, after his first experience with the DC-8 that this flying airborne laboratory, \u201c\u2026was going to make things possible that wouldn\u2019t otherwise be possible,\u201d Schwarz concluded after his first encounter with the DC-8.<\/p>\n<p>Other workshop participants went on to describe how \u2013 for nearly four decades \u2013 investigators used data collected by instruments on the DC-8 to conduct research and write papers on important scientific and engineering topics.<\/p>\n<p><em>The People Behind the Aircraft: The DC-8 Community<\/em><\/p>\n<p>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.<\/p>\n<p>\u201cLooking around the room, it\u2019s clear that what brought us together [for the workshop] is more than just an aircraft,\u201d said <strong>Nickelle Reid<\/strong> [NASA\u2019s Armstrong Flight Research Center]. \u201cIt\u2019s 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.\u201d<\/p>\n<p>This DC-8 community was well represented at this workshop and played a key role in its success. <a><\/a><\/p>\n<p><em>The DC-8 as a Means of International Engagement<\/em><\/p>\n<p>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 <a href=\"https:\/\/espo.nasa.gov\/korus-aq\" rel=\"noopener\">Korea\u2013U.S. Air Quality<\/a> (KORUS-AQ) campaign, an international cooperative air quality field study in Korea, took place in 2016.

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\u2019s Langley Research Center (LaRC) attended the workshop.<\/p>\n<p>\u00a0\u201cI mentioned I was in charge of the \u2018replacement\u2019 for the DC-8,\u201d said <strong>Martin Nowicki<\/strong> [LaRC\u2014<em>Boeing 777 Lead<\/em>]. \u201cOver the last two days, here, it\u2019s become pretty apparent that there\u2019s no \u2018replacing\u2019 the DC-8. It\u2019s carved out its own place in history. It\u2019s just done so much.\u201d<\/p>\n<p>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.<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/science.nasa.gov\/wp-content\/uploads\/2024\/05\/eo-blackseparator-line.png\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"1037\" height=\"24\" src=\"https:\/\/science.nasa.gov\/wp-content\/uploads\/2024\/05\/eo-blackseparator-line.png?w=1037\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Black Separator Line\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/science.nasa.gov\/wp-content\/uploads\/2024\/05\/eo-blackseparator-line.png 1037w, https:\/\/science.nasa.gov\/wp-content\/uploads\/2024\/05\/eo-blackseparator-line.png?resize=300,7 300w, https:\/\/science.nasa.gov\/wp-content\/uploads\/2024\/05\/eo-blackseparator-line.png?resize=768,18 768w, https:\/\/science.nasa.gov\/wp-content\/uploads\/2024\/05\/eo-blackseparator-line.png?resize=1024,24 1024w, https:\/\/science.nasa.gov\/wp-content\/uploads\/2024\/05\/eo-blackseparator-line.png?resize=400,9 400w, https:\/\/science.nasa.gov\/wp-content\/uploads\/2024\/05\/eo-blackseparator-line.png?resize=600,14 600w, https:\/\/science.nasa.gov\/wp-content\/uploads\/2024\/05\/eo-blackseparator-line.png?resize=900,21 900w\" sizes=\"auto, (max-width: 1037px) 100vw, 1037px\" \/><\/a><\/figure>\n<\/div>\n<\/div>\n<\/div>\n<p><em>Acknowledgments<\/em><\/p>\n<p>The authors wish to thank <strong>Jack Kaye <\/strong>[NASA HQ\u2014Associate Director of Research for the Earth Science Division] for his helpful reviews of the article draft.\u00a0 The first author also wishes to thank<strong> Lisa Frazier<\/strong> [NASA Headquarters\u2014<em>Strategic Events and Engagement Lead<\/em>] for providing support and assistance throughout for the in-person workshop participants. and to the Earth Science Project Office team from NASA\u2019s Ames Research Center, who performed essential conference tasks, such as website construction, audio-visual support, and food service management.
