Proba-3 Mission to Create Artificial Solar Eclipses for Sun Study

The European Space Agency's Proba-3 mission, set to launch from India, will use two satellites to create artificial solar eclipses, allowing scientists to study the Sun's corona more frequently. The mission involves precise formation flying, with the satellites maintaining a 150-meter distance with millimeter accuracy. This low-cost mission aims to solve mysteries about the Sun's corona, which is significantly hotter than its surface and influences space weather. Proba-3 is part of ESA's series of technology demonstration missions.
