In this video we’re following NASA’s Lucy spacecraft on its journey to Jupiter’s mysterious Trojan asteroids. Lucy has already stunned scientists by visiting the tiniest main-belt asteroid and discovering its oddly-shaped moon - the first contact-binary satellite ever found! Lucy will reach the Trojan swarm in 2027, hoping these ancient time capsules can shed light on our solar system’s formation: What are these ancient rocks made of? Where did they come from? And can they unlock the keys to understanding our own cosmic origins?
