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 double-satellite Proba-3 is the most ambitious member yet of ESA's Proba family of experimental missions. Two spacecraft will fly together as one, maintaining precise formation down to a single millimeter.

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 satellite will be launched by the Indian Space Research Organisation (Isro) aboard the Polar Satellite Launch vehicle (PSLV) on December 4.

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.
