Precision Mission

ISRO’s PSLV rocket will launch ESA’s Proba-3 on December 4 to study the solar corona, marking a breakthrough in “precision formation flying,” where two satellites operate as one system.

Solar Corona

Proba-3 aims to unlock the mysteries of the Sun’s outermost layer, the solar corona, where temperatures soar to 2 million degrees Fahrenheit and which influences space weather affecting Earth.

Unprecedented Eclipse

Simulating 50 solar eclipses annually, Proba-3 extends eclipse observation time from 10 minutes to six hours, offering unparalleled insights into the Sun’s elusive features.

Global Collaboration

Developed with expertise from Spain, Belgium, Poland, Italy, and Switzerland, Proba-3 showcases international teamwork, with India playing a key role in the mission’s launch.

Indian Advantage

India’s space sector gains global recognition as ISRO secures this high-profile mission, cementing its reputation as a cost-effective and reliable launch partner.

Data Access

Indian solar physicists may gain exclusive access to Proba-3 data, potentially leading to joint research opportunities with ESA and advancing solar science in India.
