AstroSat

AstroSat is the first dedicated Indian astronomy mission aimed at studying celestial sources in X-ray, optical and UV spectral bands simultaneously. The payloads cover the energy bands of Ultraviolet (Near and Far), limited optical and X-ray regime (0.3 keV to 100keV).

One of the unique features of AstroSat mission is that it enables the simultaneous multi-wavelength observations of various astronomical objects with a single satellite.

AstroSat with a lift-off mass of 1515 kg was launched on September 28, 2015 into a 650 km orbit inclined at an angle of 6 deg to the equator by PSLV-C30 from Satish Dhawan Space Centre, Sriharikota. The minimum useful life of the AstroSat mission is expected to be 5 years. (website)

Mission Objectives
                    
                     To understand high energy processes in binary star systems containing neutron stars and black holes. 
                
                     Estimate magnetic fields of neutron stars. 
                
                    Study star birth regions and high energy processes in star systems lying beyond our galaxy. 
                
                     Detect new briefly bright X-ray sources in the sky. 
                
                    Perform a limited deep field survey of the Universe in the Ultraviolet region.

            At present, all the payloads are operational and are observing the cosmic sources. 
            The spacecraft and payloads are healthy. The first six months were dedicated for performance 
            verification and calibration of payloads. After that, the science observations by the payloads began.
