ISRO Launches India's First Space Observatory Astrosat from Sriharikota


The Indian Space Research organisation on Monday successfully launched first dedicated Observatory Astrostat from Sriharikota, in Andra Pradesh. PSLV C- 30, is carrying six other co-passengers along with this astrosat, one satellite from Indonesia, one from Canada and four nano satellites from America. This is historical thing because this is first time India launching vehicle is carrying with American satellites.


Commenting on the launch Indian Space Research Organisation Chairman AS Kiran Kumar told PTI, “What it means for India is this: it is one of the first scientific missions which will be available to the Indian researcher community as an observation opportunity. This is a starting point for such things.”


Astrosat with a lift-off mass of about 1513 kg, just over 22 minutes into the flight at an altitude 650 km above the earth. orbit inclined at an angle of 6 degree to the equator by PSLV-C30.


Main Scientific Objective of ASTROSAT mission as:

  • It enables the multi-wavelength observations on various astronomical objects.
  • It observes the universe in optical, ultraviolet, low and high energy X-ray regions of the electromagnetic spectrum.
  • To understand high-energy processes in binary star systems containing neutron stars and black holes.
  • It detects bright x-ray sources in the sky.
  • It perform a limited deep field survey of the universe in the ultraviolet region.
  • Estimate magnetic fields of neutron stars.
  • Study star birth regions and high energy processes in star systems lying beyond our galaxy.

Apart from ISRO, four other Indian institutions – Tata Institute of Fundamental Research, Indian Institute of Astrophysics, Inter-University Centre for Astronomy and Astrophysics and Raman Research Institute are involved in payload development. Two of the payloads are in collaboration with Canadian Space Agency and University of Leicester, UK, ISRO said.
