ASTROSAT is India's first dedicated astronomy satellite and is scheduled to launch in mid 2008. A giant Hubble mosaic of the Crab Nebula, a supernova remnant Astronomy is the science of celestial objects (such as stars, planets, comets, and galaxies) and phenomena that originate outside the Earths atmosphere (such as auroras and cosmic background radiation). ...


After the success of the satellite-borne Indian X-ray Astronomy Experiment (IXAE), which was launched in 1996 the Indian Space Research Organization (ISRO) has approved further development for a full fledged astronomy satellite - ASTROSAT. The Indian Space Research Organisation (ISRO) is Indias national space agency. ...


A large number of leading astronomy research institutions in India and abroad are jointly building various instruments for the satellite.


Important areas requiring broad band coverage include studies of astrophysical objects ranging from the nearby solar system objects to distant stars, to objects at cosmological distances; timing studies of variables ranging from pulsations of the hot white dwarfs to active galactic nuclei(AGN)with time scales ranging from milliseconds to few hours to days.


ASTROSAT is currently proposed as a multi-wavelength astronomy mission on an IRS-class satellite into a near-Earth, equatorial orbit by the PSLV. The 5 instruments on board cover the UV(1000-3000 A), soft and hard x-ray regimes (0.3 - 8 keV; 2 - 100 keV).


Objectives of ASTROSAT

  • Multi-wavelength studies of cosmic sources
  • Monitoring the X-ray sky for new transients
  • All sky survey in the hard X-ray and UV bands
  • Broadband spectroscopic studies of X-ray binaries, AGN, SNRs, clusters of galaxies and stellar coronae
  • Studies of periodic and non-periodic variability of X-ray sources
  • Monitoring intensity of known sources and detecting outbursts and luminosity variations

Participants

ASTROSAT project is a collaborative effort of a growing list of research institutions. The current participants are:

Astrosat is an X-ray/UV astronomy observatory planned for launch in mid of the year 2007. The main mission objectives are: The Indian Space Research Organisation (ISRO) is Indias national space agency. ... This article needs to be cleaned up to conform to a higher standard of quality. ... The Indian Institute of Astrophysics (IIA), currently headquartered in Bangalore (Karnataka state), India, is a premier national institue of India for study of and research in matters pertaining to astronomy, astrophysics and related subjects. ... The Raman Research Institute was founded by Nobel laureate Sir Chandrasekhara Venkata Raman in 1948 with funds from private sources. ... The Inter-University Centre for Astronomy and Astrophysics (IUCAA) is an autonomus institution set up by the University Grants Commission to promote nucleation and growth of active groups in astronomy and astrophysics in Indian universities. ...

  • X-ray timing, with response up to hard X-rays(~100 keV)
  • Broadband X-ray spectroscopy
  • Ultraviolet Sky Survey
  • Simultaneous Multi-wavelength Monitoring of time-variable sources

To achieve these objectives,the satellite will carry the following payloads:

  1. Large-Area Xenon-filled Proportional Counters (LAXPC)
  2. A Coded-mask Camera with Cadmium-Zinc-Telluride detector array (CZT)
  3. A Soft-Xray imaging telescope with multi-foil Wolter optics and CCD detector (SXT)
  4. A deployable boom-mounted Scanning X-ray Sky Monitor consisting of three one-dimensional coded mask cameras (SSM)
  5. Two 40-cm dia Ultraviolet Telescopes for NUV and FUV coverage (UVIT)
  6. An optical monitor, which will be an attachment to the NUV telescope
  7. Charged particle monitor (CPM)

The total weight of all the instruments will be about 750 kg, and the weight of the entire spacecraft will be about 1650 kg. It will be launched by ISRO's PSLV launcher into a Low-Earth Orbiting(altitude = 600 km) circular low-inclination (near-equatorial) orbit.
