AstroSat is the first dedicated astronomy mission of India aimed at simultaneous multi-wavelength observations of celestial sources in X-ray, ultraviolet and limited optical spectral bands. The satellite was launched from Satish Dhawan Space Centre, Sriharikota on 28 September 2015 by PSLV-C30 (XL) in its 30th consecutive successful flight. The satellite was placed in an orbit with an altitude of 650 km and 6 orbital inclination. Currently, all the payloads are operational and observations are underway. The mission life is expected to be 5 years.Keywords

Scanning Sky Monitor (SSM) on-board AstroSat is a wide-field imager to monitor the X-ray sky in the energy band 2.5-10 keV. The primary science objective of SSM is to detect and locate transient X-ray sources in the sky. Once detected the information is to be provided to the astronomical community for follow-up observations to do a more detailed study of the source. Long-term monitoring of known X-ray transient sources is also one of the science objectives of SSM. The instrument constitutes three units of 1D positionsensitive propotional counters with coded masks on each, all three mounted on a platform capable of rotation to scan about 50% of the sky in one full rotation. The angular resolution of each unit in SSM is 12' x 2.5°. Sensitivity of SSM is ~30 milliCrab at 3 sigma in 10 min integration time. This article briefly discusses the instrument and a few early results since the launch of AstroSat.Keywords

Aditya-L1 is the first Indian space mission to study the Sun. The mission is aimed at studying the Sun from a halo orbit around the Sun-Earth Lagrangian point 1, which is about 1.5 million kilometres from the Earth. It carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun, the corona, in different wavebands. The spacecraft and payloads are under development. Aditya-L1 is expected to be launched during the 2019-20 time-frame by PSLV-XL.Keywords

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.Keywords
