Studying Trojan Asteroids with Lucy

Launching in 2021, NASA's Lucy Mission will fly by seven different Trojan asteroids that are orbiting the same distance from the Sun as Jupiter. The mission will address the following science objectives:

Surface Geology - Lucy will map the albedo, shape, crater spatial and size-frequency distributions, determine the nature of crustal structure and layering, and determine the relative ages of surface units.

Surface Color and Composition - Lucy will map the color, composition and regolith properties of the surface of the Trojan asteroid and determine the distribution of minerals, ices, and organic species.

Interiors and Bulk Properties - Lucy will determine the masses and densities, and study sub-surface composition via excavation by craters, fractures, ejecta blankets, and exposed bedding.

Satellites and Rings - Lucy will look for rings and satellites of the Trojan asteroids.
