Astrosat, the first reserved cosmic astronomical observatory, completed decades of operations on Sunday (September 28, 2025).
Ten years ago, September 28, 2015, Astrosat was launched by a PSLV-C30 (XL) from Satish Dhawan Space Center in a 3-year mission. Although the designed life of Astrosat has been for five years, it continues to provide valuable data.
In the last decade, the Observatory has made the main interesting discoveries with five payloads on board.
The Indian cosmic research organization, which resembles a milestone in Post X, said: “On that day 10 years ago was Astrosat, the first Indian astronomical observatory with more wavelengths that started ISRO. From black holes to neutron stars, from the nearest star Centauri to the first FUV Photons detection X -rays with high energy.

Five payloads
Astrosat has been designed to observe the universe in a visible, ultraviolet, low -energy X -ray area of the electromagnetic spectrum at the same time using its five payloads.
Five scientific useful loads on board satellite are ultraviolet imaging telescope (UVIT), X-ray proportional counter (LAXPC), cadmium-zinc-stelluride display (CZTI), soft X-ray (SXT) and SSM monitor (SSM).
Astrosat has been realized by ISRA with the participation of all major astronomical institutions, including Inter University Center for Astronomy and Astrophysics (IUCAA) PUNE, Tata Institute of Fundamental Research (TIFR) in Mumbai, Indian Institute for Astrophysics (IIAP) and Ramana Research Institute (RRI) In India and Twor Indities in India.
