Rank 30 documents Lucy — the 821 kg Goddard / SwRI Discovery spacecraft touring eight asteroids including seven Jupiter Trojans and main-belt Donaldjohanson on a twelve-year cruise launched 16 October 2021 aboard Atlas V 401. Hal Levison's team uses Earth gravity assists to reach L4 and L5 Lagrange points where primitive bodies preserve formation-era chemistry no planetary surface survived. L'LORRI and L'TES instruments will compare Trojan spectra across the population, testing migration models for the outer solar system. The distinctive circular solar arrays echo the mission's long cruise endurance. Heritage Collector renders the stippled spacecraft, Trojan asteroid trail, and arched navy window exactly as the master PNG dictates.
