Isro to launch Europe's Proba-3 to create artificial eclipse, study the Sun

The Indian Space Research Organisation is set to launch Europe's Proba-3 mission, a pioneering project that employs two spacecraft working in tandem to study the Sun's corona and measure its energy output with unprecedented precision. The Occulter will position itself between the Coronagraph and the Sun, creating an artificial eclipse that allows the Coronagraph to observe the Sun's faint corona, typically obscured by the solar disk's intense brightness. DARA will provide continuous measurements of the Sun's total energy output, known as total solar irradiance. The Proba-3 mission's unique highly elliptical orbit, reaching up to 60,000 km from Earth, will offer new perspectives on solar observation.
