The Indian Space Research Organisation (ISRO) has achieved a significant feat with the successful launch of the Proba-3 spacecraft. On December 5, 2024, this collaborative mission with the European Space Agency (ESA) lifted off from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, demonstrating India’s advancing capabilities in space exploration.
Launched at 4:04 PM, the PSLV-C59 rocket carried a payload of 550 kg, after overcoming a previous delay linked to a propulsion issue. The Proba-3 mission is groundbreaking, marking the first instance of precision formation flying in space with two satellites, the Coronagraph and the Occulter, maintaining a distance of 150 meters apart. The Occulter will obscure the Sun’s center, allowing the Coronagraph to examine the Sun’s outer atmosphere, known as the Corona, which plays a crucial role in space weather.
After a successful deployment, ISRO confirmed that all systems were functioning optimally across its monitoring stations. Proba-3’s orbit was established at approximately 600 km at perigee and 60,000 km at apogee. This endeavor not only enhances India’s status in the realm of space research but also represents a pivotal advancement in heliophysics, vital for understanding solar phenomena. ISRO’s Chairman congratulated the teams involved, highlighting the collaboration’s innovative spirit and future goals. This project, aptly termed “Proba,” signifies a commitment to exploration and discovery.
ISRO’s Proba-3 Mission: A New Era in Space Science and Exploration
Overview of Proba-3 and ISRO’s Contributions
The Indian Space Research Organisation (ISRO) has taken a significant step forward in space exploration with the launch of the Proba-3 spacecraft on December 5, 2024. This collaborative mission with the European Space Agency (ESA) underscores India’s growing prominence in the global space arena. By successfully deploying the PSLV-C59 rocket from the Satish Dhawan Space Centre, ISRO not only showcased its technological prowess but also contributed to a mission that specializes in solar observation.
Key Features of Proba-3
Proba-3 is distinguished by its innovative approach to precision formation flying. For the first time, it employs two satellites—the Coronagraph and the Occulter—operating in tandem with a precise distance of 150 meters apart. This formation allows the Occulter to block the Sun’s central light, enabling the Coronagraph to observe the solar Corona. This region holds valuable insights into solar winds and space weather phenomena, which can have profound effects on satellite operations and communication on Earth.
