Two new NASA missions will take a look at relics from the birth of the solar system. Lucy (left) will explore six Trojan asteroids, which share the orbit of Jupiter, while Psyche (right) will orbit the metallic asteroid 16 Psyche, which could be the battered core of a would-be planet that never formed. Both missions are scheduled for launch in the next decade. [SWRI/SSL/Peter Rubin]
