After Moon, ISRO is going to the Sun: Meet Aditya-L1
Produced by: Tarun Mishra
Designed by: Mohsin Shaikh
India's Space Research Organization's (ISRO) solar space-based observatory, Aditya-L1, is scheduled for a launch in the last week of August or in the first week of September. Previously, the launch window was expected between August 26-28, but the agency has not yet confirmed the precise dates
Aditya-L1 Launch
The satellite, fabricated at the UR Rao Satellite Centre in Bengaluru, has been transported to ISRO's spaceport in Sriharikota, Andhra Pradesh, as confirmed by the national space agency. It will be transported into space using a PSLV rocket
Crafting and Transport
Aditya-L1 is designed to orbit around the Sun-Earth L1 Lagrange point, situated approximately 1.5 million km from Earth, providing an unobstructed view of the Sun devoid of occultations or eclipses

ISRO emphasises that this strategic positioning offers continuous and real-time monitoring of solar activities and their influence on space weather
Enhanced Solar Observation
Equipped with seven payloads, Aditya-L1 will investigate various layers of the Sun, including the photosphere, chromosphere, and outer corona, utilising electromagnetic particles and magnetic field detectors
Multi-layered Insight
Four payloads on the satellite will directly observe the Sun, while the remaining three will perform in-situ analyses of particles and fields, crucially expanding our understanding of solar dynamics' impact on the interplanetary medium
Dual Payload Function
The mission's primary scientific aims encompass a spectrum of studies ranging from upper solar atmospheric dynamics to unravelling processes preceding solar eruptive events
Focused Objectives
Aditya-L1's instruments are meticulously calibrated to study the solar atmosphere, with a specific focus on the chromosphere and corona. Simultaneously, in-situ instruments will analyse the environment at the L1 point
In-depth Calibrations
The Aditya-L1 mission is anticipated to offer key insights into phenomena like coronal heating, coronal mass ejections, flare activities, space weather dynamics, and particle and field propagation
Data Insights
With its advanced instruments and unique orbit, Aditya-L1 aims to provide comprehensive insights into the intricate workings of the Sun's various layers, helping researchers understand solar behaviour and its impact on our space environment
