"India's Twin Satellites to Simulate Eclipse for Sun Corona Study"

The European Space Agency (ESA) is preparing to launch the Proba-3 mission on India's PSLV rocket to demonstrate precision formation flying and create an artificial eclipse. This mission involves two satellites, an Occulter and a Coronagraph, flying 150 meters apart to block out the Sun's light and study the solar corona. The mission aims to provide insights into coronal mass ejections and measure the Sun's energy output, potentially advancing our understanding of space weather and Earth's climate. The Proba-3 mission is a pioneering step towards new formation-flying space telescopes.
