ISRO's AstroSat observatory completes 11 years in orbit
AstroSat, India's first dedicated space-based observatory, completed eleven years on September 28, more than double its intended lifespan. Launched aboard PSLV-C30 in 2015, it observes simultaneously in ultraviolet, X-ray and gamma-ray bands. The mission has studied black holes, neutron stars, supernova remnants and galaxies, and its CZTI instrument has tracked about 750 gamma-ray bursts. AstroSat data has led to more than 570 research papers in international journals.
