NASAs New Discovery Missions

On Jan. 4, NASA announced the selection of two missions to explore previously unexplored asteroids.

The first mission, called Lucy, will study asteroids, known as Trojan asteroids, trapped by Jupiters gravity. The Psyche mission will explore a very large and rare object in the solar systems asteroid belt thats made of metal, and scientists believe might be the exposed core of a planet that lost its rocky outer layers from a series of violent collisions.

Lucy is targeted for launch in 2021 and Psyche in 2023. Both missions have the potential to open new windows on one of the earliest eras in the history of our solar system a time less than 10 million years after the birth of our sun.
