Introduction to the Proba-3 Mission

On Wednesday, ISRO launched the European Space Agency’s Proba-3 mission from the Satish Dhawan Space Centre in Sriharikota. This mission, focused on studying the Sun’s corona, is a milestone in ISRO’s collaboration with international space agencies. It involves two satellites working in tandem to simulate an artificial solar eclipse.

Mission Objectives and Technology

Proba-3 consists of the Occulter Satellite (OSC) and the Coronagraph Satellite (CSC). The OSC blocks sunlight using a 1.4-meter disc, creating a shadow where the CSC can observe the Sun’s corona without interference. This setup allows for continuous six-hour observations—far longer than natural eclipses.

Significance for ISRO and Global Impact

This launch underscores ISRO’s technological advancements and its emergence as a reliable partner for international missions. Historically dependent on foreign agencies, ISRO has now launched over 300 satellites globally. The Proba-3 mission further solidifies India’s leadership in space research and international cooperation, reflecting its growing prowess and commitment to advancing scientific exploration.
