India's first multi-wavelength space telescope, AstroSat, has successfully detected its 600th Gamma-ray Burst (GRB), an event named GRB 231122B.
About AstroSat:
It is India’s firstdedicated multi-wavelength space observatory aimed at studying celestial sources in X-ray, optical, and UV spectral bands simultaneously.
AstroSat, with a lift-off mass of 1515 kg, was launched by the Indian launch vehicle PSLV from Satish Dhawan Space Centre, Sriharikota, on September 28, 2015, into a 650 km orbit inclined at an angle of 6 degrees to the equator.
The spacecraft control centre at Mission Operations Complex (MOX) of ISRO Telemetry, Tracking and Command Network (ISTRAC), Bengaluru, managesthe satellite during its entire mission life.
The minimum useful life of the AstroSat mission is around 5 years.
It carries a total of five scientific payloads, enabling imaging and studying the temporal and spectral properties of galactic and extra-galactic cosmic sources in a wide range of wavelengths on a common platform.
Scientific 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.
