India’s first astronomical satellite Astrosat: India’s first astronomical satellite “Astrosat” has successfully launched. It has launched from Satish Dhawan Space Centre, Sriharikota. Astrosat is one of the India’s major scientific missions of ISRO. Astrosat will study multi wavelength data using payloads. It contains 6 different instruments to perform different works. 6 other commercial satellites (4 from US and 1 from Indonesia and 1 from Canada) will ride along with this Astrosat. These foreign satellites were launched by ISRO. India’s first astronomical satellite is equivalent of the Hubble telescope. It was launched by NASA in 1990.
Astrosat features: India’s first astronomical satellite Astrosat
- Astrosat is India’s first dedicated and multi-wavelength space observatory.
- India’s first astronomical satellite will perform multi band observations of wavebands, included Ultra-violet (UV), optical, low and high energy X-ray. Astrosat will also perform observations on the study “Black holes”. The operating lifetime of Astrosat is 5 year.
- The polar satellite launch vehicle took the India’s first astronomical satellite Astrosat into the space.
- Astrosat has been placed at low equatorial orbit with altitude of 650km
- It is equipped with 5 payloads which contains 6 instruments.
Payloads in Astrosat:
- Ultra violet imaging telescope will perform imaging in three channels.
- Soft X-ray Imaging Telescope (SXT) will perform X-ray imaging to observe remote object in the X-ray spectrum.
- Cadmium zinc Tellurium imager is a hard Imager which consists of detector array.
- Scanning Sky monitor (SSM) consists of three proportional sensitive counters. It has large field of view (FOV) to detect X-ray transient sources.
- The LAXPC instrument to study of X-ray timing and low resolution spectral studies.
- Charged particle monitor (CPM) to study of LAXPC, SXT and SSM.
Conclusion: India’s first astronomical satellite
India has now its own space observatory like US, Japan, Russia and Europe. This is the third time when India has put Astrosat in an earth Orbit along with seven commercial satellites, in a single mission.
