Lucy Mission Overview: Journey to Explore the Trojan Asteroids

The Lucy Mission aims to explore a variety of celestial objects over 12 years, focusing on Trojan asteroids that orbit Jupiter. These asteroids are remnants from the early solar system, offering insights into planet formation. The mission will visit several asteroids, including a main belt asteroid named Donald Johansson, and conduct a rehearsal to ensure the spacecraft's readiness. The mission will explore both leading and trailing Trojan swarms, including a binary object, Patroclus and Menoetius. By studying these small bodies, scientists hope to understand the conditions of the early solar system and the processes that shaped the planets.

What is the primary goal of the Lucy Mission?

• To observe distant galaxies

• To find new planets

• To study the evolution of the solar system

• To explore the surface of Mars

What are Trojan asteroids?

• Asteroids that orbit the Sun between Mars and Jupiter

• Asteroids that follow or lead Jupiter in its orbit

• Asteroids that orbit Earth

• Asteroids that are found in the Kuiper Belt

Why is the asteroid named Donald Johansson significant to the Lucy Mission?

• It is the largest asteroid in the solar system

• It contains water ice

• It is the first asteroid to be visited by the mission

• It is named after the discoverer of the Lucy Fossil

What is unique about the binary object Patroclus and Menoetius?

• They are the largest objects in the asteroid belt

• They are two Trojans that orbit a common center of mass

• They are composed entirely of metal

• They are the only asteroids with rings

Why are small bodies like asteroids important for understanding the early solar system?

• They are easier to study than planets

• They are the only source of precious metals

• They provide insights into the conditions of the early solar system

• They have changed significantly since the planets formed
