Lucy and Co.: A Comprehensive Guide for Exploring the Depths of the Cosmos

Introduction

The Lucy and Co. mission, named after the remarkable Australopithecus afarensis fossil discovered in 1974, is a NASA-led expedition that seeks to unravel the mysteries surrounding the solar system's early history and the potential for life beyond Earth. Launched on October 16, 2021, the mission comprises a spacecraft and a suite of scientific instruments designed to investigate the Jovian Trojans, a group of asteroids believed to hold remnants of the primordial material that formed the solar system.

Mission Overview

Lucy will embark on a 12-year journey, utilizing gravity assists from Earth and Mars to reach its primary targets:

• (52246) Donaldjohanson: A pristine D-type Trojan named after the discoverer of Lucy the fossil.
• (3548) Eurybates: A binary Trojan system with a large, cratered primary and a smaller, oddly shaped secondary.
• (15094) Polymele: A triple Trojan system, including a main binary pair and a smaller, icy object.
• (11351) Leucus: A large, elongated Jupiter Trojan with a complex surface morphology.
• (21900) Orus: A comparatively small, reddish Trojan with a composition unlike any other previously studied.

Scientific Objectives

The Lucy mission has several key scientific objectives, including:

• Characterizing the Diversity of Trojan Asteroids: Studying the physical and chemical properties of the Trojans to understand their origin, evolution, and potential for harboring water or organic matter.
• Exploring the Origin of Planets: Investigating the Trojans to shed light on the accretion processes that led to the formation of the outer solar system.
• Searching for Jovian Trojans with Moons: Determining the prevalence of moons around Jupiter Trojans, which could provide insights into the formation and stability of planetary systems.
• Understanding the Role of Collisions: Studying the collisional history of Trojans to assess their contribution to the delivery of materials to the terrestrial planets.

Instrumentation

To achieve these objectives, Lucy carries a suite of scientific instruments:

• L'TES: Long-Wavelength Thermal Emission Spectrometer
• Ralph: Visible and Infrared Imaging Spectrometer
• LEISA: Lucy Enviromental Investigation Scanner
• OCA: Lucy Orbital Camera
• TDS: Terminal Dust Sensor

Benefits of the Mission

The Lucy mission promises to deliver significant benefits to our understanding of the solar system and beyond:

• Advancement of Planetary Science: Providing new insights into the Jovian Trojans, which represent a major component of the solar system's outer regions.
• Insights into the Genesis of Life: Understanding the composition and potential habitability of Trojans may shed light on the origins of life in our solar system and elsewhere.
