/ AstroSat MISSION
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.
After injection into Orbit, the two solar panels of AstroSat were automatically
deployed in quick succession. The spacecraft control centre at Mission Operations
Complex (MOX) of ISRO Telemetry, Tracking and Command Network (ISTRAC), Bengaluru
manages the satellite during its entire mission life.
The science data gathered by five payloads of AstroSat are telemetered to the ground
station at MOX. The data is then processed, archived and distributed by Indian Space
Science Data Centre (ISSDC) located at Bylalu, near Bengaluru.

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