ISRO will launch the European Space Agency's (ESA) Proba-3 mission on December 4. The Indian Space Research Organisation (ISRO) will launch the European Space Agency’s (ESA) Proba-3 mission, dedicated to studying the Sun’s corona, the outermost layer of its atmosphere.

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 twin spacecraft that arrived in India earlier this month has been integrated and stacked at the Satish Dhawan Space Centre in Sriharikota primed for launch.

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.

India's ISRO is launching ESA's Proba-3 mission on December 4th from Sriharikota. This mission will study the Sun's corona using two satellites flying in precise formation, simulating a continuous solar eclipse.

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.
