Aditya-L1 Achieves Milestone in Space Research, Kerala PSUs Play Key Role

India's mission to study the sun, Aditya-L1, has made a significant stride by establishing a halo orbit around the Lagrangian point L1 on Saturday. This event not only marks a leap in space research but also underscores the critical contributions of a consortium of public sector units (PSUs) hailing from Kerala. These PSUs, comprising Keltron, Steel and Industrial Forgings Limited (SIFL), Travancore Cochin Chemicals (TCC), and Kerala Automobiles Ltd. (KAL), played pivotal roles in the mission's success.

ISRO-PSUs Collaboration: A Synergy for Success

The Kerala Industries Minister, P. Rajeeve, recognized the efforts of these PSUs for their contributions to the mission. Keltron, in particular, was responsible for supplying 38 electronic modules for the Polar Satellite Launch Vehicle (PSLV-C57) which launched the mission on September 2, 2023. The company also facilitated in testing various electronic modules. SIFL's contribution included various types of forgings, including those utilized in propellant tanks and the Vikas rocket engine. TCC supplied a significant quantity of sodium chlorate crystals, totalling 150 tonnes, while KAL manufactured components for the spacecraft separation system. This collaboration between ISRO and the state PSUs exemplifies the harmony between national space objectives and local industrial capacities.

Aditya-L1 successfully completed the Halo-Orbit Insertion (HOI) at 16.00 Hrs on January 6, 2024. Currently, the spacecraft is approximately 1.5 million km from earth, positioned on the continuously moving Sun – Earth line, with an orbital period of about 177.86 earth days. This achievement not only demonstrates ISRO's capabilities in executing complex orbital maneuvers but also bolsters confidence to undertake future interplanetary missions.

Looking Forward: A Beacon for Future Missions

The spacecraft will now initiate observing the Sun and studying phenomena radiating from it. The mission carries seven payloads designed to monitor the photosphere, chromosphere, and the outermost layers of the Sun. Prime Minister Narendra Modi congratulated the scientists on their achievement, and the mission's success indicates ISRO's prowess and assurance in managing future interplanetary missions. The collaboration of PSUs with ISRO in the Aditya-L1 mission underscores India's evolving capabilities in space exploration, fostering a promising future in the field.
