  • India’s first multi-wavelength space observatory in 2015
  • 6 billion year old vampire star captured – called blue straggler
  • Launch Vehicle: PSLV — C30
  • Understand high energy processes in binary star systems - neutron stars & 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
  • Ultraviolet Imaging Telescope (UVIT) : Observe Visible, Near Ultraviolet and Far Ultraviolet regions of electromagnetic spectrum.
  • Large Area X-ray Proportional Counter (LAXPC) : Study variations in emission of X-rays from sources like X-ray binaries, Active Galactic Nuclei and other cosmic Sources.
  • Soft X-ray Telescope (SXT) : Studying X-ray spectrum of 0.3 - 8 keV range from distant celestial bodies.
  • Cadmium Zinc Telluride Imager (CZTI) : Function in X-ray region, sense X-rays of high energy in 10 - 100 keV range
  • Scanning Sky Monitor (SSM) : Scan sky for long term monitoring of bright X-ray sources in binary stars, and detect and locate sources that become bright in X-rays for a short duration.

Polar Satellite Launch Vehicle (PSLV)

  • Payload Fairing: Can place multiple payloads into orbit- > Multi-payload adaptors are used in the payload fairing - > Allows feat of 20 satellites launch
  • Strap -On Boosters: 6 solid rocket strap-on motors by the first stage in its PSLV-G and PSLV-XL variants – not used in core alone version
  • 1st Stage: PS1 is the first stage of PSLV and it provides the launcher
  • 2nd Stage: PS2 & is powered by the Vikas liquid engine
  • 3rd Stage: PS3 & penultimate stage of PSLV, and it uses a solid rocket motor
  • 4th Stage: PS4 as final stage with two liquid engines
