Summary:
- The article discusses the European Space Agency's (ESA) PROBA-3 mission, which aims to study the Sun's outer atmosphere, known as the solar corona.
- PROBA-3 will consist of two satellites that will fly in precise formation, allowing them to create a large, stable "coronagraph" that can observe the solar corona without being obscured by the Sun's bright surface.
- This unique setup will provide new insights into the dynamics and structure of the solar corona, which is crucial for understanding the Sun's activity and its impact on Earth's environment.
