A diamond-shaped crest houses artworks of the Lucy fossil at left, the Lucy spacecraft at center, and an artist's impression of a Jupiter trojan. The word "Lucy" is written in a large, bold red font at the top right corner, while the words "First to the Trojans" and "SWRI · NASA · LM" are written in a smaller white font across the bottom edges of the diamond-shaped crest.

Lucy is a NASA space probe on a twelve-year journey to eight different asteroids. It is slated to visit two main belt asteroids as well as six Jupiter trojans – asteroids that share Jupiter's orbit around the Sun, orbiting either ahead of or behind the planet.[4][5] All target encounters will be flyby encounters.[6] The Lucy spacecraft is the centerpiece of a US$981 million mission.[7] It was launched on 16 October 2021.

On 4 January 2017, Lucy was chosen, along with the Psyche mission, as NASA's Discovery Program missions 13 and 14 respectively.[6][8]

The mission is named after the Lucy hominin fossils, because study of the trojans could reveal the "fossils of planet formation": materials that clumped together in the early history of the Solar System to form planets and other bodies.[9] The hominid was named after the 1967 Beatles song "Lucy in the Sky with Diamonds".[10] The spacecraft carries a disc made of lab-grown diamonds for its L'TES instrument.[11]
