Anticipation Builds for Proba-3 Launch
On December 4, 2024, at precisely 4:08 PM IST, the Indian Space Research Organisation (ISRO) is set to initiate the launch of the Proba-3 satellites in collaboration with the European Space Agency (ESA). This notable event will take place at the prestigious Satish Dhawan Space Centre located in Sriharikota, Andhra Pradesh.
The mission involves the Polar Satellite Launch Vehicle-XL (PSLV-XL) and is recognized as an “In-Orbit Demonstration” (IOD) mission. This groundbreaking project showcases the synergy between NewSpace India Limited (NSIL), ISRO, and ESA, highlighting advancements in space technology through international cooperation.
The PSLV-C59 will carry two spacecraft— the Coronagraph Spacecraft (CSC) and the Occulter Spacecraft (OSC)—stacked together during launch. Designed to operate as one cohesive unit, these satellites will fly in tandem, precisely maintaining a fixed distance of 150 meters as they align with the Sun. This unique formation will enable continuous observation of the Sun’s elusive corona.
The CSC, weighing 310 kilograms, is equipped with a variety of scientific instruments, while the 240-kilogram OSC features optical heads and innovative propulsion systems. This mission promises to pave the way for future advancements in space exploration and technology. As ISRO embarks on this exciting venture, the world watches in anticipation of its success.
Countdown to the Future: Exploring the Innovations of the Proba-3 Mission
Overview of the Proba-3 Launch
