The Proba-3 satellite will be launched by the Indian Space Research Organisation (Isro) aboard the Polar Satellite Launch vehicle (PSLV) on December 4.

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.

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 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 rocket is scheduled to take off from Sriharikota, as part of the PSLV C-59 mission that is a commercial collaboration between European Space Agency and ISRO via NewSpace India Ltd

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.

ISRO will launch the Proba-3 mission next Wednesday. Two satellites will fly 150 meters apart. One satellite will block the Sun's light. The other sat

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.
