NASA's Lucy spacecraft completed its first asteroid flyby on April 20, 2025, passing by asteroid 52246 Donaldjohanson as a preparatory encounter before reaching its primary targets, the Trojan asteroids. The flyby revealed that Donaldjohanson has a double-lobed structure, providing valuable data about this small asteroid's composition and shape. This encounter served as an important test of Lucy's instruments and navigation systems ahead of its main mission objectives.
Why it matters
This practice flyby allows mission scientists to validate Lucy's imaging systems and scientific instruments before the spacecraft reaches the more scientifically significant Trojan asteroids. Understanding the structure of small asteroids like Donaldjohanson contributes to our knowledge of early solar system formation and helps refine techniques for studying similar objects.
On its way to future encounters with Trojan asteroids, the Lucy spacecraft made a practice run past tiny asteroid 52246 Donaldjohanson on April 20, 2025. Today, the Lucy team, led […]
