The satellites will be launched onboard PSLV-XL from ISRO's Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh on 4 December. The Proba (PRoject for OnBoard Autonomy) missions are a series of in-orbit demonstration (IOD) missions from the European Space Agency, for demonstrating and validating new technologies and concepts in orbit.

Among the rocket's various configurations, the PSLV-XL stands out due to its enhanced capabilities, particularly for missions like the upcoming launch of the Proba-3 satellite.

The MOI-TD platform is being launched with the support of the Indian National Space Promotion and Authorization Center (IN-SPACe), the central agency that facilitates private-sector involvement in the space industry, India Today reported.

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.

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 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.

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.

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.
