ESA’s Proba-3 mission has achieved a world first. It created an artificial eclipse in space. Not just once, but over 50 times. In this video, we’ll discover how these two tiny probes are revolutionising our ability to study the Sun’s inner corona, and helping to answer the biggest unsolved mysteries about our star.

#Astrum #Space #Eclipse
Astrum explores the Proba-3 mission, a pioneering feat of engineering involving two autonomous satellites flying in precise formation. By creating artificial solar eclipses in space, these spacecraft allow researchers to bypass the limitations of ground-based observations to study the sun's mysterious atmosphere with unprecedented continuity and detail.
