PSCL Proba-3 Mission: An ISRO-ESA Effort toward the Precision Observations of the Sun

On 4 December 2024, the Indian Space Research Organisation (ISRO) will be ready to conduct a highly expected launch mission for the PSLV-XL carrying the ESA's Proba-3. ISRO and ESA have successfully reached hands together for an effort aiming towards revolvement of our perception about sun's corona which is a sun's outermost solar atmosphere.

The two precision satellites, the Occulter and the Coronagraph, will be carried aboard a PSLV-XL rocket, which is known to carry extra payload because of its added strap-on boosters. Together, the two will create artificial solar eclipses, allowing scientists to observe the dynamics of the Sun in ways previously unimagined. The two satellites will fly together in tandem with about 150 meters between them, blocking sunlight for up to six hours to observe the corona continuously. This extended observation window will offer valuable insights that typical solar observations can't capture, hence improving our understanding of solar weather and its effects on Earth.

The Proba-3 mission marks a major breakthrough in space exploration with regard to the first-ever precision formation flying mission around the globe. This is of major importance for observing solar phenomena, which cannot be otherwise captured because of the brightness of the Sun. The data related to solar events like solar flares and CMEs would be very much critical to capture from the Coronagraph placed behind the Occulter.

The PSLV-XL will take off on 4:08 PM IST from ISRO's spaceport at Sriharikota on December 4. With the Proba-3 mission, the collaboration of ISRO and ESA showcases growing India as a player in the global field of space research. Further, ISRO establishes its position as a reliable launch partner in the international domain.

The Proba-3 mission is a continuation of ISRO and ESA's series of successful partnerships, underlining the scientific value of these collaborations. Scientists study the Sun's corona in such detail with an aim to discover more about the solar activities that have played a critical role in the space weather, from affecting the communications of satellites to Earth's climate.

With the spacecraft now successfully integrated onto the payload fairing of PSLV, and a launch rehearsal completed, ISRO is poised to score another first on its journey through the annals of space exploration. Proba-3 is not just a tremendous scientific effort but also a testament to growing Indian presence in global compositeness related to space.
