India's ISRO and the European Space Agency (ESA) are collaborating to launch the Proba-3 mission, aimed at studying the Sun's outermost layer, the solar corona. This marks another milestone in international space cooperation, demonstrating the synergy between the two space agencies.
Scheduled for December 4, the Proba-3 mission focuses on precision formation flying to study the Sun's solar corona. The solar corona is the Sun’s outermost and hottest layer, critical to understanding solar activity and its impact on Earth. ESA highlights this mission as the world’s first precision formation flying venture, setting a benchmark for future solar and space studies.
The Indian Space Research Organisation’s (ISRO) Polar Satellite Launch Vehicle (PSLV) will carry the Proba-3 payload. Known for its versatility and reliability, PSLV has been instrumental in ISRO’s success. For this mission, PSLV will launch ESA’s satellites into a highly elliptical orbit, emphasizing its capability for complex orbital deployments.
The launch is set to take place at Sriharikota spaceport in Andhra Pradesh at 4:08 PM on Wednesday, December 4. Sriharikota has been the site of numerous successful launches, cementing India’s position as a global space leader.
The mission is facilitated by NewSpace India Limited (NSIL), ISRO’s commercial arm. NSIL plays a key role in fostering international partnerships, ensuring commercial viability, and promoting India’s space expertise globally.
Weighing 550 kg, the Proba-3 satellites will operate in a unique highly elliptical orbit. This configuration enables close monitoring of the solar corona, providing unprecedented precision in solar observation. The advanced formation flying technology employed in Proba-3 represents a groundbreaking achievement in space science.
The solar corona plays a critical role in understanding solar wind, coronal mass ejections, and space weather phenomena. Insights from Proba-3 will contribute significantly to predicting solar storms, safeguarding satellites, and protecting power grids on Earth.
This joint mission highlights the growing collaboration between India and Europe in space exploration. By working together, ISRO and ESA combine their expertise, resources, and innovation to achieve greater scientific advancements.
ISRO’s involvement in missions like Proba-3 underscores its global reputation for affordability, reliability, and technological excellence. The success of such partnerships positions India as a key player in international space research and collaboration.
