Isro Is Launching Proba-3 To Block The Sun: What Is The Motive Behind Artificial Eclipse

The European Space Agency's (ESA) Proba-3 mission is set to revolutionized solar observation by creating an artificial solar eclipse in space

Using a pair of satellites working in tandem, the mission aims to study the Sun's corona a challenging but critical region of the Sun's outer atmosphere like never before

The Proba-3 satellite will be launched by the Indian Space Research Organization (Isro) aboard the Polar Satellite Launch vehicle (PSLV) on December 4

The Proba-3 mission consists of two satellites, the Occulter Satellite (OSC) and the Coronagraph Satellite (CSC)

The OSC carries a 1.4-meter occulting disc designed to block sunlight, creating a shadow approximately eight centimeters wide at a distance of 150 meters

Positioned within this shadow is the CSC, which houses a telescope with a 5-centimeter aperture

These satellites will maintain a precise formation, with millimetric accuracy, using formation-flying techniques

Its artificial eclipse will allow continuous observation of the corona for six hours during each 20-hour orbit, offering a hundredfold increase in observation time compared to natural eclipses

The mission will focus on the gap region between the low and high corona, which has been difficult to study until now

Proba-3 represents a significant leap forward in solar research, promising unprecedented insights into the Sun's dynamics and its impact on space weather.
