ISRO Successfully Launches Proba-3 Satellites: A Milestone in Space Collaboration
ISRO's PSLV Successfully Launches European Proba-3 Satellites, Simulating Solar Eclipse Through Precision Orbit
The Indian Space Research Organisation (ISRO) successfully launched its Polar Satellite Launch Vehicle (PSLV), marking another big step in its space program. The PSLV carried the European Space Agency’s (ESA) Proba-3 satellites into their correct orbit with great precision. The launch happened at 4:04 PM on December 5, 2024, from the Sriharikota launch station in Andhra Pradesh. This success shows ISRO’s growing capabilities and value of international collaboration in promoting space exploration.

A Flawless Launch Despite Initial Delays
Originally scheduled for December 4, 2024, the launch of the Proba-3 satellites was postponed due to the detection of an anomaly in the satellites. On its 61st flight, ISRO’s PSLV operated well despite the delay. This flight demonstrated once more that the PSLV is dependable & adaptable rocket that can manage various satellite types & mission objectives.
Success of this mission also highlights ISRO’s expertise in managing complex missions and addressing last-minute challenges effectively. The ability and accuracy of the Proba-3 mission are shown by its successful launch into a highly elliptical orbit.
Proba-3 Satellites: A Unique Mission in Space Science
The Proba-3 mission, developed by the European Space Agency (ESA), is an innovative project aimed at demonstrating advanced formation-flying technology in space.
It includes two satellites:
- Coronagraph Spacecraft (CSC)
- Occulter Spacecraft (OSC)
These two satellites work together to achieve scientific goals.
Two satellites will fly in close formation while maintaining precise control over their relative position and orientation. This configuration is designed to simulate a total solar eclipse, enabling scientists to study the Sun’s corona—the outermost part of its atmosphere. Space exploration & solar observation are made possible by this unique method.

Advanced Formation-Flying Technology
At the heart of the Proba-3 mission is its ability to perform precision formation-flying. With the help of this cutting-edge technology, two spacecraft can operate as a single unit in space, precisely maintaining constant distance & alignment. This creative strategy represents a major advancement in satellite technology & opens the door for future multi-satellite operations that are more intricate.
Coronagraph Spacecraft will monitor Sun’s corona while Occulter Spacecraft will obscure Sun’s light and cast a shadow in space. By simulating a total solar eclipse, this technique gives researchers a unique chance to examine Sun’s outer atmosphere, which is normally hidden by the brightness of the Sun.
A Historic First in Space Exploration
ISRO confirmed that Proba-3 is the ESA’s first mission of its kind and the world’s first to use precision formation flying. This innovative project shows how coordinated satellite operations can open new possibilities for research and exploration. Its successes show how important international collaboration is for addressing difficult scientific problems.
The Role of PSLV in Proba-3
Polar Satellite Launch Vehicle (PSLV) from ISRO was crucial to the Proba-3 mission. PSLV has a solid performance history & is renowned as India’s reliable rocket. It launched two satellites into space on this mission, each weighing 545 kg. The satellites were positioned in their orbit, 600 kilometers above Earth, about eighteen minutes after launch.
This mission adds to the PSLV’s impressive legacy of over 60 successful flights, further establishing its position as a preferred launch vehicle for international clients.
Building on Past Success: Proba-1
The second ESA satellite to be launched on an Indian rocket is the Proba-3 mission. Proba-1 was the first, launched with the PSLV in 2001. Originally intended to be a one-year mission, Proba-1 has contributed to Earth observation and research for more than 20 years. This demonstrates its robust architecture and ISRO’s rockets’ dependability.
The success of Proba-1 set the stage for upcoming ISRO and ESA partnerships, highlighting the importance of pooling resources and experience to accomplish shared objectives in space exploration.
Strengthening International Collaboration
Proba-3 launch’s success is sign of ISRO and ESA’s growing collaboration. The importance of international cooperation in space technology development and scientific research is exemplified by this relationship. By building on each other’s strengths, ISRO and ESA are expanding our understanding of the universe and setting new benchmarks for innovation and reliability in space operations.
