NASA's Lucy spacecraft successfully completed its flyby of the asteroid Donaldjohanson, confirming the spacecraft is healthy and beginning data transmission back to Earth. This milestone prepares the mission for its primary study of Jupiter Trojan asteroids starting in 2027.

Why it matters: The flyby provides valuable data on a young asteroid, advancing our understanding of solar system formation.

The big picture: This encounter is a key step before Lucy targets Jupiter Trojan asteroids, shedding light on early solar system history.

The stakes: Data transmission may take up to a week, requiring precise operations to ensure mission success.

Commenters say: Many reflect on the surreal pandemic-era work on this mission and appreciate the asteroid’s name honoring paleoanthropologist Lucy.
