Explanation – The PROBA-3 mission, led by the European Space Agency (ESA), focuses on demonstrating precision formation flying of two spacecraft in space. This involves testing and validating technologies that allow multiple spacecraft to fly in close formation with high precision, which is crucial for future space missions. The mission also includes scientific observations, such as studying the Sun’s corona using a coronagraph, but its primary goal is to showcase formation flying techniques.
