The innovative team of engineers and scientists from NASA, the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and more than 40 other partner organizations across the country that created the Parker Solar Probe mission has been awarded the 2024 Robert J. Collier Trophy by the National Aeronautic Association (NAA). This annual award recognizes the most exceptional achievement in aeronautics and astronautics in America with respect to improving the performance, efficiency, and safety of air or space vehicles in the previous year.
“Congratulations to the entire Parker Solar Probe team for this well-earned recognition,” said NASA acting Administrator Janet Petro. “This mission’s trailblazing research is rewriting the textbooks on solar science by going to a place no human-made object has ever been and advancing NASA’s efforts to better understand our solar system and the Sun’s influence, with lasting benefits for us all. As the first to touch the Sun and fastest human-made object ever built, Parker Solar Probe is a testament to human ingenuity and discovery.”
An artist’s concept of NASA’s Parker Solar Probe. NASA On Dec. 24, 2024, Parker Solar Probe made its closest approach to the Sun, passing deep within the Sun’s corona, just 3.8 million miles above the Sun’s surface and at a top speed of close to 430,000 mph, ushering in a new era of scientific discovery and space exploration.
“This award is a recognition of the unrelenting dedication and hard work of the Parker Solar Probe team. I am so proud of this team and honored to have been a part of it,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “By studying the Sun closer than ever before, we continue to advance our understanding of not only our closest star, but also stars across our universe. Parker Solar Probe’s historic close approaches to the Sun are a testament to the incredible engineering that made this record-breaking journey possible.”
Three novel aerospace technology advancements were critical to enabling this record performance: The first is the Thermal Protection System, or heat shield, that protects the spacecraft and is built to withstand brutal temperatures as high as 2,500 degrees Fahrenheit. The Thermal Protection System allows Parker’s electronics and instruments to operate close to room temperature.
Additional Parker innovations included first-of-their-kind actively cooled solar arrays that protect themselves from overexposure to intense solar energy while powering the spacecraft, and a fully autonomous spacecraft system that can manage its own flight behavior, orientation, and configuration for months at a time. Parker has relied upon all of these vital technologies every day since its launch almost seven years ago, in August 2018.
“I am thrilled for the Parker Solar Probe team on receiving this well-deserved award,” said Joe Westlake, director of the Heliophysics Division at NASA Headquarters. “The new information about the Sun made available through this mission will improve our ability to prepare for space weather events across the solar system, as well as better understand the very star that makes life possible for us on Earth.”
Parker’s close-up observations of solar events, such as coronal mass ejections and solar particle events, are critical to advancing our understanding of the science of our Sun and the phenomena that drive high-energy space weather events that pose risks to satellites, air travel, astronauts, and even power grids on Earth. Understanding the fundamental physics behind events which drive space weather will enable more reliable predictions and lower astronaut exposure to hazardous radiation during future deep space missions to the Moon and Mars.
“This amazing team brought to life an incredibly difficult space science mission that had been studied, and determined to be impossible, for more than 60 years. They did so by solving numerous long-standing technology challenges and dramatically advancing our nation’s spaceflight capabilities,” said APL Director Ralph Semmel. “The Collier Trophy is well-earned recognition for this phenomenal group of innovators from NASA, APL, and our industry and research partners from across the nation.”
First awarded in 1911, the Robert J. Collier Trophy winner is selected by a group of aviation leaders chosen by the NAA. The Collier Trophy is housed in the Smithsonian’s National Air and Space Museum in Washington.
“Traveling three times closer to the Sun and seven times faster than any spacecraft before, Parker’s technology innovations enabled humanity to reach inside the Sun’s atmosphere for the first time,” said Bobby Braun, head of APL’s Space Exploration Sector. “We are all immensely proud that the Parker Solar Probe team will join a long legacy of prestigious aerospace endeavors that redefined technology and changed history.”
“The Parker Solar Probe team’s achievement in earning the 2024 Collier is a shining example of determination, genius, and teamwork,” said NAA President and CEO Amy Spowart. “It’s a distinct honor for the NAA to acknowledge and celebrate the remarkable team that turned the impossible into reality.”
Parker Solar Probe was developed as part of NASA’s Living With a Star program to explore aspects of the Sun-Earth system that directly affect life and society. The Living With a Star program is managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland, for NASA’s Science Mission Directorate in Washington. The Applied Physics Laboratory designed, built, and operates the spacecraft and manages the mission for NASA.

Susan Lederer: Guiding Science in Real Time
Official portrait of CLPS Project Scientist Susan Lederer.NASA/Bill Stafford Susan Lederer, IM-2 project scientist, has spent years ensuring all the NASA instruments are fully prepared for lunar operations. She oversees real-time science operations from IM’s Nova Control Center, working to maximize the mission’s scientific return and prepare for the next generation of astronauts to explore the Moon, Mars, and beyond.
“We have done our best with remote data, but the only way to truly understand the Moon—how to drill for resources, how to live on another celestial body—is to go there and do the experiments,” she said. “Now, we get to do that.”
Lederer’s path to CLPS was shaped by a background in space exploration, astrophysics, and planetary science. She has contributed to multiple spacecraft missions, including NASA’s Deep Impact mission, which sent a projectile into Comet Tempel 1, and a separate mission that retrieved a sample from asteroid Itokawa.
On Ascension Island, a remote joint U.S. Air Force and Royal Air Force base, she co-led the construction of a 20,000-pound optical telescope to study space debris. Her work spans collaborations with the Defense Advanced Research Projects Agency, a tenure as a physics professor, and the design of impact experiments at NASA’s Experimental Impact Lab, where she used a vertical gun firing projectiles at speeds exceeding those of sniper rifles to study asteroid and comet collisions.
Lederer has logged hundreds of hours conducting observing runs at professional observatories worldwide, where she refined both her scientific precision and her ability to repair instruments while working alone on remote mountaintops.
As a private pilot and SciComm (the science equivalent of Capsule Communicator) for NASA’s Desert Research and Technology Studies, she honed her mission communication skills. She was also part of an international team that discovered two extrasolar planetary systems—one with a single Earth-sized planet and another with seven—orbiting ultracool red dwarf stars.
Her expertise has uniquely prepared her to oversee real-time science operations for lunar missions in high-intensity environments.

NASA/Robert Markowitz Lederer emphasizes the importance of both scientific discovery and the practical realities of living and working on another world—a challenge NASA is tackling for the first time in history.
“Honestly, it’s when things don’t go as planned that you learn the most,” she said. “I’m looking forward to the surprises that we get to solve together as a team. That’s our greatest strength—the knowledge and teamwork that make this all happen.”
Lederer credits the success of CLPS lunar deliveries to the dedication of teams working on payloads like Polar Resources Ice Mining Experiment-1 and Lunar Retroreflector Array, as well as peers within NASA’s Science Mission Directorate, Space Technology Mission Directorate, and Intuitive Machines.
“What we do every day in CLPS creates a new world for exploration that is efficient in schedule, cost, and gaining science and technology knowledge in these areas like we’ve never done before,” said Lederer. “It feels very much like being a trailblazer for inspiring future generations of explorers – at least that’s my hope, to keep the next generation inspired and engaged in the wonders of our universe.”

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.
Photo 1. NASA’s DC-8 flying laboratory flew Earth science missions for NASA’s. Airborne Science Program (ASP) from 1987–2024. The versatile aircraft was used to conduct a variety of research experiments that spanned all seven continents. Photo credit: Lori Losey [NASA’s Armstrong Flight Research Center (AFRC)] More information is available about the full history of ASP, its primary objectives, and its many achievements in an archived article: see “Flying in the ‘Gap’ Between Earth and Space: NASA’s Airborne Science Program” [The Earth Observer, September–October 2020, 32:5, 4–14].
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.

In addition, Spanish filmmaker Rafael Luis Méndez Peña debuted a trailer for his documentary film, NASA-817, on October 24 and took photographs during the workshop. The ??? agenda a workshop recording ???, and other related materials are available through the NASA History Office.
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.
Photo 3. International collaborations included educational endeavors.

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.

One of the most popular student investigations flown on the DC-8 (and other ASP aircraft) was (is) the Student Airborne Research Program (SARP), in which upper-level undergraduate students can gain valuable hands-on experience conducting field research. Students taking part in SARP and their mentors posed with the DC-8 at AFRC in 2019 [top] and in 2022 [bottom]. The 2022 SARP group flew flights over California’s Central Valley to study air quality.

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.
