CAPE CANAVERAL, Fla.— NASA’s Lucy spacecraft, launched in 2021, successfully completed a flyby of the asteroid Donaldjohanson on april 20, 2025, marking a crucial step in its 12-year mission to study the Trojan asteroids orbiting Jupiter. This encounter served as a vital test of the spacecraft’s instruments and capabilities before it reaches its primary targets.
A “thorough Trial” Before the main Event
The flyby of Donaldjohanson, which occurred at 1:51 p.m. EDT, allowed the Lucy team to test its suite of scientific instruments. These include L’Ralph, which captures colour images and infrared spectra; L’LORRI, a high-resolution long-range reconnaissance imager; and L’TES, a thermal emission spectrometer. These instruments are designed to analyze the composition and surface properties of asteroids.
“We will observe [Donaldjohanson] It is as if it is one of the trojan asteroids, because we want to conduct a thorough trial,” said Professor Phil Christensen from Arizona State University, L’TES designer. The goal, he said, was to find out the composition of the asteroid.
The data collected during the Donaldjohanson flyby will be crucial for refining Lucy’s observation strategies for its encounters with the Trojan asteroids. These asteroids are remnants from the early solar system and could provide valuable insights into the formation and evolution of the planets.
Honoring Lucy and Her discoverer
The Lucy mission itself is named after the famous 3.2-million-year-old hominin fossil discovered in Ethiopia in 1974. This fossil, an Australopithecus afarensis, provided groundbreaking evidence about human evolution. The asteroid Donaldjohanson is named after paleoanthropologist Donald Johanson, the discoverer of the Lucy fossil and founder of the institute of Human Origins at Arizona State University.
The connection between the spacecraft, the fossil, and the asteroid highlights the mission’s aspiring goal of understanding the origins of our solar system and, by extension, the origins of life itself. The trojan asteroids are believed to be composed of materials similar to those that formed the outer planets, offering a glimpse into the early conditions of our cosmic neighborhood.
During a video interview, Christensen asked Johanson what he would name any secondary asteroids discovered during the flyby, should they exist. Johanson responded, “Oh, I have to really think about it.”
Why Study Trojan Asteroids?
Scientists believe the Trojan asteroids hold vital clues about the early solar system. Unlike asteroids in the asteroid belt between Mars and Jupiter, the Trojans share Jupiter’s orbit, making them a unique population of space rocks. Their composition and location suggest they may have formed far from the Sun and were later captured into their current orbits.
Studying these asteroids could help answer essential questions about the building blocks of planets and the processes that shaped our solar system. The Lucy mission aims to determine the surface compositions, masses, and volumes of the Trojan asteroids, as well as search for moons and rings.
The Challenge of Studying Distant Asteroids
One of the main challenges of the Lucy mission is the vast distance and small size of the Trojan asteroids. From Earth, these objects appear as faint points of light, making it tough to study their properties in detail. Lucy’s flybys will provide close-up observations, allowing scientists to analyze their surfaces and compositions with unprecedented accuracy.
The spacecraft is equipped with advanced navigation and guidance systems to ensure it can accurately target and fly by each asteroid. The mission also relies on sophisticated interaction technology to transmit data back to Earth, allowing scientists to analyze the results and plan future observations.
While some critics argue that the resources allocated to deep space missions like Lucy could be better spent addressing problems on Earth, proponents emphasize the importance of scientific exploration for expanding our knowlege and inspiring future generations. The discoveries made by Lucy could have far-reaching implications for our understanding of the universe and our place within it.
Future Encounters and Mission Timeline
Following the Donaldjohanson flyby, Lucy will continue its journey toward the Trojan asteroids. It is indeed scheduled to encounter its first Trojan asteroid in 2027. The mission is designed to study a diverse range of Trojan asteroids, including those with different sizes, shapes, and colors.
The Lucy mission is expected to last until at least 2033,providing scientists with over a decade of valuable data about the Trojan asteroids. The results of this mission could revolutionize our understanding of the early solar system and provide new insights into the formation of planets.

Archyde Interview: Dr. Aris Thorne on NASA’s Lucy Mission and the Donaldjohanson Flyby
Interview Introduction
Welcome, Archyde readers! Today, we have the privilege of speaking with Dr. Aris Thorne, lead mission scientist for the Lucy mission’s instrument suite, to discuss the recent prosperous flyby of asteroid Donaldjohanson and the exciting journey ahead.Dr. Thorne, welcome!
The Donaldjohanson Flyby: A Crucial Test
Archyde: Dr. Thorne, the Donaldjohanson flyby was a important milestone. Could you elaborate on why this encounter was so significant for the Lucy mission, and what specific data was collected?
Dr. Thorne: Thank you for having me. The Donaldjohanson flyby was essentially a dress rehearsal for the main event—the Trojan asteroids. It allowed us to thoroughly test all of lucy’s instruments. We where able to verify the performance of L’Ralph, L’LORRI, and L’TES, ensuring they’re calibrated and ready for the diverse Trojan asteroids. We gathered essential data on the asteroid’s composition, surface features, and thermal properties.
Instruments in Action: Unveiling Asteroid Secrets
Archyde: Could you delve deeper into the capabilities of the primary instruments, L’Ralph, L’LORRI, and L’TES, and how they’ll be used to understand the Trojan asteroids?
Dr. Thorne: Absolutely. L’Ralph provides color images and infrared spectra, helping us determine the surface composition. L’LORRI gives us high-resolution images, revealing surface details like craters and features. L’TES measures thermal emission, which helps us determine the asteroid’s composition, including surface texture and, essentially, how it interacts with solar radiation. Together, they paint a very detailed picture.
The Trojan Treasure : Insights on Formation
Archyde: The Trojan asteroids are remnants of the early solar system. What key questions do you hope to answer by studying them?
Dr. Thorne: We are eager to understand how the outer solar system, and possibly how planets like Jupiter, formed. By studying the Trojan components, we hope to learn about the building blocks of planets, processes of planetary formation, and the early conditions of our cosmic neighborhood.
Challenges and the Road Ahead
Archyde: What are some of the biggest challenges in studying these distant objects, and what does the mission timeline look like from here?
Dr. Thorne: The distance and size of the Trojans are definitely the biggest hurdles. However, the spacecraft’s instrumentation and systems are fully equipped to mitigate these challenges. Following the Donaldjohanson flyby, Lucy will encounter its first Trojan asteroid in 2027. The mission extends until at least 2033, providing over a decade’s worth of data, and hopefully even uncovering more deep space secrets!
the Future of Deep Space Missions
Archyde: There are arguments to be made about allocating resources to missions such as Lucy. How do you believe this mission contributes to society and the development of mankind?
Dr. Thorne: It is indeed a fair question to ask and a very critically important one.By studying our planet’s origins and how we got here, we are essentially trying to understand our own roots as well as making new advances in the realm of astrophysics. It’s a quest for knowledge that is hard to quantify,but will undoubtedly result in scientific breakthroughs that benefit all.
