Launch of NASA's Lucy Mission to Jupiter's Trojan Asteroids (Official NASA Broadcast)

Set a reminder: Our Lucy mission is scheduled to launch on Sat., Oct. 16 at 5:34 a.m. EDT (9:34 UTC) to ancient asteroids called Trojans. The Trojan asteroids are rocky worlds as old as our solar sys...

Lucy: The First Mission to the Trojan Asteroids

Lucy will be the first space mission to study Jupiter's Trojan asteroids. The Trojans may be remnants of the primordial material that formed the outer planets, and serve as time capsules from the birth of our solar system more than 4 billion years ago.

Overview

Destination: Heliocentric N/A
Mission: Robotic Exploration

Heliocentric N/A Space Launch Complex 41 Cape Canaveral SFS, FL, USA Probability: 90%

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.
