The spacecraft launched to study Jupiter’s Trojan asteroids, named Lucy, is designed to be the farthest from the Sun while running exclusively on solar power.

NASA’s Lucy mission, launched in October 2021, is the first space mission to study the Trojan asteroids associated with Jupiter. It uses large solar arrays to generate power, which is a significant technological achievement for a mission operating in the outer solar system where sunlight is much weaker.

Previous missions to the outer solar system relied primarily on Radioisotope Thermoelectric Generators (RTGs) for power. The Lucy mission’s solar panels are exceptionally large (about the width of a tennis court) to capture enough sunlight at the distance of Jupiter’s orbit. The Trojan asteroids are remnants from the formation of the solar system, orbiting in two swarms, one leading and one trailing Jupiter.
