The Indian Space Research Organization (ISRO) is on the brink of launching another groundbreaking solar mission named ‘Aditya-L1’ on September 2, following the successful Chandrayaan-3 endeavour. This upcoming mission signifies a significant leap for ISRO as it embarks on its inaugural dedicated mission to investigate the Sun.
Dubbed ‘Aditya-L1’ after the heart of our solar system, this mission aims to improve our knowledge of the dynamics of the sun and space weather. “Most likely the launch will take place on September 2 “, an ISRO official said as quoted by the news agency PTI.
Aditya-L1’s primary objective is to attain unparalleled insights into the Sun’s behaviour. To accomplish this, the spacecraft will position itself within a halo orbit around Lagrange point 1 (L1) of the Sun-Earth system, stationed approximately 1.5 million kilometres away from Earth. Unlike previous missions, Aditya-L1 will remain free from the hindrances of eclipses and occultation, providing scientists with an uninterrupted view of the Sun and enabling real-time study of solar activities and their repercussions on space weather.
With a suite of seven advanced payloads, Aditya-L1 is prepared to meticulously analyse multiple layers of the Sun. These layers range from the photosphere and chromosphere to the outermost layer, known as the corona. The payloads employ a combination of electromagnetic, particle, and magnetic field sensors to capture essential data for comprehending phenomena such as coronal heating, solar flares, coronal mass ejections, and more.
A defining feature of Aditya-L1’s mission lies in its unique viewpoint from Lagrange point 1. This positioning grants four payloads a direct and unobstructed line of sight to the Sun, while the remaining three payloads will delve into in-situ examinations of particles and fields at this strategic vantage point. The synergy between these observations promises to unveil the enigmatic facets of solar dynamics and their influence on the interplanetary medium.
Anticipation surrounds the outcomes of Aditya-L1’s payload. The collected data is anticipated to illuminate the intricacies of the solar corona, its heating mechanisms, magnetic field configurations, and the progression of coronal mass ejections. By deciphering these elements, researchers aspire to decode the sequence of events that lead to solar eruptions and contribute to a more profound understanding of the drivers behind space weather phenomena.
In essence, Aditya-L1’s impending mission launch signifies India’s bold stride into solar exploration and promises a wealth of knowledge about the Sun’s intricate workings and its effects on our cosmic neighbourhood.
