任务简介
Lucy是首个探索和研究特洛伊小行星的任务。特洛伊小行星是围绕太阳运行的两组小行星，分别位于木星轨道前后。由于这些小行星在数十亿年间一直处于如此稳定的轨道上，它们作为早期太阳系的遗迹具有极大的研究价值。 Lucy是由NASA戈达德太空飞行中心和科罗拉多州博尔德市西南研究院领导的NASA任务。在12年的时间里，Lucy将飞越七颗不同的特洛伊小行星以及一颗主带小行星。访问所有目标的复杂轨迹将包括多次地球重力辅助。
原文
Lucy is the first mission to explore and study Trojan asteroids. The Trojans are a type of asteroids that orbit the Sun in two groups, in front of and behind Jupiter in its orbit around our star. Since these asteroids have been in such stable orbits for billions of years, they are of great interest as remnants of early Solar System. Lucy is a NASA mission led by NASA Goddard and Southwest Research Institute in Boulder, Colorado. Over the course of 12 years, Lucy will fly by seven different Trojan asteroids and also one main belt asteroid. The complex trajectory to visit all targets will include several Earth gravity assists.
