ESA's Proba-3 mission, launched by ISRO, will study the Sun’s corona with innovative formation flying technology.

The Indian Space Research Organisation (ISRO) has announced the launch of the European Space Agency's (ESA) Proba-3 mission on December 4. The mission is designed to study the Sun’s faint corona near its solar rim with remarkable precision.

ESA revealed that the choice of PSLV was strategic — it offers the perfect balance of capability and cost for the Proba-3 mission, which involves a payload of 550 kg. The payload will involve two satellites that are part of the payload,

The Proba-3 mission continues ESA's suite of solar missions, following the successful launches of Proba-1 (2001) and Proba-2 (2009), which were also launched by ISRO.

India’s rocket PSLV is all set to launch a pair of unique experiments developed by the European Space Agency on December 4. First in the world, Proba-3 mission will see two satellites in a formation parallel to each other for long durations.

The ESA's Proba-3 mission will launch from India on December 4, using ISRO's PSLV-XL to explore the Sun's corona through precise formation flying. This collaboration highlights India's growing reputation in space technology.

The European Space Agency admitted that ISRO's PSLV is a more cost-effective alternative to its own heavy-lift Ariane-6 and medium-lift Vega-C rockets. The three instruments onboard Proba-3 will help unravel the scientific mystery of why the solar corona is significantly hotter than the sun itself.
