The Inception of Bepi Colombo

Bepi Colombo is named after Giuseppe 'Bepi' Colombo, the Italian scientist who developed the gravity assist technique. This technique uses the gravitational pull of planets to propel spacecraft, a method that has become a staple in interplanetary travel. The mission, launched in October 2018, embodies the spirit of international collaboration, combining ESA's and JAXA's expertise to tackle the complexities of exploring the innermost planet of our solar system.

Mission Objectives

The primary goal of Bepi Colombo is to conduct a comprehensive study of Mercury. This includes investigating its magnetic field, exosphere, surface geology, and internal structure. By doing so, scientists aim to gain insights into the planet's formation and evolution, which could, in turn, offer clues about the early solar system.

Key Objectives Include:

Magnetic Field Analysis: Understanding the dynamics and origins of Mercury's magnetic field.
Surface Composition: Mapping the surface and identifying its mineralogical makeup.
Exosphere Dynamics: Studying the thin atmosphere and its interactions with solar winds.
Interior Structure: Investigating the planet's core and mantle to understand its geologic activity.

MMO: Dedicated to studying Mercury's magnetosphere with magnetometers and plasma instruments.
Propulsion Module: Utilizes ion propulsion for efficient long-duration travel.

Propulsion and Navigation

The journey to Mercury is not a straightforward path. Bepi Colombo's route involved multiple gravity assists—flybys of Earth, Venus, and Mercury itself—to gain the necessary velocity and trajectory adjustments. This intricate dance through the solar system highlights the precision of interplanetary navigation.

Gravity Assist Technique:

Earth Flyby: Provided the initial velocity boost post-launch.
Venus Flybys: Adjusted trajectory and reduced velocity for Mercury insertion.
Mercury Flybys: Fine-tuned approach for orbital insertion.
