ASTROSAT, India’s first astronomy satellite, has been built for simultaneous observations in a broad range of wavelengths: visible, near-ultraviolet (NUV), far-UV (FUV), soft X-rays to hard X-rays. There are five principal scientific payloads to be carried aboard the satellite: (i) a Soft X-ray Telescope (SXT), (ii) three Large Area Xenon Proportional Counters (LAXPCs), (iii) a Cadmium-Zinc-Telluride Imager (CZTI), (iv) two Ultra-Violet Imaging Telescopes (UVITs) one for visible and near-UV channels and another for far-U V, and (v) three Scanning Sky Monitors (SSMs). It will also carry a charged particle monitor (CPM). All the instruments have been integrated after being tested individually for the launch and space environment, and the entire satellite is now being tested in a thermo-vac chamber. ASTROSAT is due to be launched by India’s Polar Satellite Launch Vehicle (PSLV) in the first week of October 2015, in a circular 600 km orbit with an inclination of ~6 degrees, from the Sriharikota launching station. A brief description of the instruments and their capabilities, along with the possible scientific programs will be presented.
