Asteroid flyby for NASA's Lucy mission
Asteroid flyby for NASA's Lucy mission
An artist's impression of NASA's Lucy spacecraft approaching the asteroid (52246) Donaldjohanson, which measures nearly four kilometres across. Lucy’s flyby on 20 April 2025, at a distance of 960 kilometres and a speed of 13.4 kilometres per second, will serve as a dress rehearsal for the study of the trojan asteroids in Jupiter's orbit, which the probe will reach in 2027/28 and again in 2033. The science team expects the satellite images of Donaldjohanson to reveal features as small as 50 metres.
