The overarching objective of this mission, known as PSLV-C57, is to engage in real-time observations of solar activities and their profound influence on space weather. By meticulously studying and understanding these solar dynamics, the Aditya-L1 solar mission aspires to provide invaluable insights into this celestial body’s behavior and its repercussions on our surrounding cosmic environment.

Following a journey lasting over an hour from liftoff, the PSLV executed a precise maneuver, injecting the Aditya-L1 spacecraft into an elliptical orbit with dimensions of 146 miles at its closest approach and an impressive 12,117 miles at its farthest point from Earth. Notably, this marked the inaugural occasion when the launch vehicle’s upper stage employed two distinct burn sequences to ensure the spacecraft reached its intended orbit with precision and accuracy.

ISRO Chairman S. Somanath expressed his congratulations to the PSLV team for their innovative mission approach during the launch of Aditya-L1. Speaking from the space agency’s mission control center, he stated, “Today, the PSLV has demonstrated a unique mission approach to successfully position the Aditya-L1 spacecraft in its designated orbit. Following this, Aditya-L1 will embark on its journey after executing specific Earth maneuvers. Let us extend our best wishes to the Aditya spacecraft as it embarks on its extended journey, ultimately reaching its destination within the halo orbit of L1.”

The instruments aboard the Aditya-L1 spacecraft have been meticulously designed to investigate and study the Sun’s three critical components: the photosphere, the chromosphere, and the corona. Additionally, the trio of instruments dedicated to on-site experiments will be focused on observing the immediate environment surrounding the Lagrangian point L1. This comprehensive approach will provide a deeper understanding of the Sun’s various layers and their influence on our solar system.

The Aditya-L1 solar mission, which received an allocation of approximately $46 million from the Indian government in 2019, was initially conceived back in 2008 with the primary objective of scrutinizing the solar corona, the Sun’s outermost layer of the atmosphere. This significant undertaking was aptly named “Aditya,” a term that signifies “sun” in Hindi, reflecting its dedication to solar exploration.

However, as the mission evolved and expanded in scope, the Indian Space Research Organization (ISRO) made the strategic decision to rename it “Aditya-L1.” This nomenclature change was reflective of the mission’s broader mission objectives, encompassing the study of not only the solar corona but also the intricate solar and space environments. By encompassing this wider perspective, Aditya-L1 has positioned itself as a comprehensive solar mission with the potential to unveil a multitude of scientific insights into our closest star, the Sun.

“The realization of this mission is truly a dream come true for the Aditya-L1 team,” expressed Nigar Shaji, the project director for the Aditya-L1 mission. She added, “Upon the commissioning of the Aditya mission, it will undoubtedly serve as a valuable asset to the field of heliophysics within our nation and contribute significantly to the global scientific community.”

Historically, space agencies such as those in the U.S., Europe, and China have undertaken missions dedicated to solar observation in outer space. Remarkably, this marks India’s debut in this domain, representing the first instance of the country venturing into space for solar research. Previously, India had primarily concentrated its solar observation efforts utilizing ground-based telescopes.

The Indian space agency garnered global attention and acclaim just last week with the successful soft landing of Chandrayaan-3 on the lunar surface.
