ISRO gears up for yet another history-defining launch with PSLV-C59 carrying ESA’s Proba-3 spacecraft. ISRO will launch the mission on 4th December 2024, at 4:08 PM IST, aiming to revolutionize solar observation. The PSLV-C59 will lift off from the First Launch Pad at the Satish Dhawan Space Centre in Sriharikota.This launch represents a massive collaboration between India and Europe.
Proba-3: A Unique Spacecraft Duo
The Proba-3 mission includes two distinct satellites, the Coronagraph Spacecraft (CSC) and the Occulter Spacecraft (OSC), operating together. Both will work on precision formation flying to precisely maintain 150 meters away from each other. Alligning them perfectly with each other will allow for artificial solar eclipses such that uninterrupted views of the Sun’s corona would be available for a protracted period of time.
Proba-3 revolutionizes the approach to solar studies. Contrasting with ground-based observatories, this space-based system would eliminate atmospheric interference and bring cleaner data. Also, with its ability to block directly the Sun’s light for a continuous period of time, it stands out against traditional coronagraphs.
Scientific Objectives: Shedding Light on the Corona
The mission is focused on the Sun’s corona, which is its outermost layer of atmosphere. This region holds critical clues to solar dynamics, such as solar flares and coronal mass ejections. These events have a very large impact on space weather, affecting satellites, communication systems, and power grids on Earth.
Proba-3 would be equipped with advanced technology and capture detailed observations of the corona. Scientists would hope to understand the mysteries of accelerated solar wind and magnetic dynamics. The mission would have further implications on the better understanding of the Sun-Earth connection, thereby illuminating the space weather-forecasting capabilities.
PSLV-C59: The Work Horse of Indian Space Missions
ISRO’s Polar Satellite Launch Vehicle (PSLV) continues to prove its versatility and reliability. The PSLV-C59 mission is the 61st flight of this iconic rocket and the 21st time that the XL configuration has been used. This variant features additional strap-on boosters, which allow it to carry heavier payloads with accuracy.
The rocket will place the 550 kg Proba-3 spacecraft into an accurate orbit. ISRO engineers have optimized every element of the launch vehicle to ensure mission success. Preparations at the Satish Dhawan Space Centre remain on schedule, with rigorous tests confirming the readiness of all systems.
Advancing Technology Through Collaboration
The Proba-3 mission is a great collaboration between ISRO and ESA. It shows how the world is so interconnected in space exploration, where shared expertise accelerates progress. ESA designed the Proba-3 spacecraft, while ISRO provides its trusted launch vehicle and infrastructure. Together, they will achieve scientific breakthroughs that benefit humanity.
This mission showcases a remarkable technological highlight: precision formation flying. The ability to achieve such precise coordination and control between orbiting spacecraft remains unmatched. Future missions, including space-based telescopes and multi-satellite arrays, can leverage these advanced techniques.

Wider Implications of the Mission
The success of PSLV-C59 and Proba-3 mission will add to India’s stature as a reliable partner in global space initiatives. It will also reinforce ISRO’s position as a leader in low-cost, high-efficiency satellite launches. For ESA, this mission underlines its commitment to advancing solar science and exploring new frontiers.
The knowledge from the Proba-3 experiment will add to numerous subjects: astrophysics, prediction of space weather and high-technology engineering on a satellite. And by that, the mission actually presents how international cooperation has to overcome complicated scientific and technological problems and inspires an international approach to uniteness.
With PSLV-C59 and Proba-3, ISRO and ESA are on a journey to understand the Sun. Their teaming up is a culmination of engineering excellence and scientific curiosity. The Proba-3 mission is a testament to human ingenuity, proving that when nations join hands, the possibilities can be endless.
