India’s first dedicated multi-wavelength satellite, AstroSat, was launched by PSLV C30 from the Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh on 28 September 2015. It is India’s first multiwavelength observatory. AstroSat carries five scientific payloads and is capable of simultaneous observations from ultraviolet to very hard X-rays. It has completed five years of on-board operations in September 2020 as a proposal-based observatory. Currently, it has close to 1500 global users and has resulted in more than 150 articles in peer-reviewed journals. This article is an overview providing a brief description of the AstroSat mission and some recent results using data from this unique Indian space observatory.
