In an exciting breakthrough for solar research, two European satellites launched from India are prepared to transform our understanding of the sun by orchestrating artificial solar eclipses. This innovative mission features the satellites flying in a meticulously planned formation, with one satellite casting a shadow over the other for an impressive six hours—far longer than any natural solar eclipse experienced on Earth. This extraordinary duration offers scientists unparalleled opportunities to investigate the sun’s corona, which is integral to comprehending solar activity and phenomena that could disrupt power systems on our planet.

The mission, termed Proba-3, serves as a demonstration of advanced technology, with the satellites maintaining a precise distance of 492 feet apart. Employing cutting-edge GPS and laser systems ensures their exact alignment. The European Space Agency’s technology director emphasized the significant scientific implications of this project. Over the course of two years, the mission is designed to generate hundreds of artificial eclipses, with initial findings expected to emerge by March next year following rigorous equipment testing.

With a budget of $210 million, Proba-3 promises to shed light on why the corona is hotter than the sun’s surface while simultaneously piloting high-precision formation flying technology—laying the groundwork for future space exploration initiatives. Following the conclusion of this two-year mission, the satellites will re-enter Earth’s atmosphere, culminating their journey in a spectacular display.

Exploring the Sun: The Game-Changing Proba-3 Mission Opens New Frontiers in Solar Research

## Introduction

The ongoing Proba-3 mission, launched by the European Space Agency (ESA) from India, marks a significant leap in our quest to understand the sun and its influence on Earth. By executing artificial solar eclipses, this innovative endeavor is poised to revolutionize solar research and enhance our capability to predict solar events that can impact technology and infrastructure on our planet.
