Important Points to Know about ISRO’s Astrosat:
Dear Readers, Important points to know about ISRO’s Astrosat which was recently launched successfully was given here, which will be more helpful for the candidates those who are preparing for the upcoming exams.
Astrosatis India’s first dedicatedmulti wavelength space observatory and 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.
Functions of Astrosat:
· Astrosat will observe universe in the optical, ultraviolet, low and high energy x-ray regions of the electromagnetic spectrum
· Multi-wavelength observations of Astrosat can be further extended with co-ordinate observations using other spacecraft and ground based observations
· It has lift –off mass of about1513kg. It will be launched into a650km orbit inclined at an angle of 6 deg to the equator by pSLV-C30 and two solar panels of Astrosat are automatically deployed in quick succession.
· Its mission life will be managed by Mission Operation Complex (MOX) of ISRO telemetry, Tracking and Command Network (ISTRAC) at Bangalore.
The scientific objectives of Astrosat mission are
· To understand high energy processes in binary star systems containing neutron stars and black holes
· Estimate Magnetic field of neutron stars
· Study star birth regions and high energy processes in star system lying beyond our galaxy
· Detect new briefly bright X-ray sources in the sky
· Perform limited deep field survey of the universe in the Ultraviolet region.
Payloads of Astrosat
5 payloads of Astrosat are chosen to facilitate a deeper insight into various astrological processes
· UVIT– The Ultra Violet Imaging Telescope capable of observing sky in the visible, near and far ultraviolet regions of the electromagnetic spectrum
· LAXPC– Large Area X-ray Proportional Counter designed for study of various emissions of X-rays from sources like X-ray binaries, Active Galactic Nuclei and other cosmic sources
· CZIT– Cadmium Zinc Telluride Imager functioning in the X-ray region, extend the capability to sense X-rays of high energy in 10-100 keV range
· SSM– Scanning Sky Monitor to scan the sky for bright X-ray sources in binary stars and detect the location of bright X-rays for a short duration of time
· SXT– Soft X-ray telescope is designed for studying the X-ray spectrum of 0.3 – 8 keV range coming from distant celestial bodies
· The science data gathered by 5 payloads of Astrosat are telemeter to the ground station at MOX.
· India’s Polar satellite Launch Vehiclesuccessfully launched ASTROSAT from Satish Dhawan Space Centre, Sriharikotta. This was the30thconsecutive success for PSLV
· The 320 ton, 45 m tall PSLV-C30 carrying seven satellites weighed about 1631kg at lift-off.
International customer satellites of PSLV-C30
· LAPAN-A2is a microsatellite from National Institute of Aeronautics and Space –LAPAN, Indonesia
· NLS-14 (EV9), a nanosatellite from space flight Laboratory, University of Toronto
· 4 LEMUR nanosatellites from Spire Global, Inc, USA, are non-visual remote sensing satellites.
