About Aditya-L1

  • India’s first space-based observatory to study the sun. 
  • The spacecraft will be placed in a halo orbit around the Lagrange point 1 (L1) of the sun earth system, which is about 1.5 million km from the earth.
  • Project Director: Nigar Shaji (native of Tenkasi, Tamil Nadu)
  • 7 Payloads: The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the sun. They are 
  1. Visible Emission Line Coronagraph (VELC)
  2. Solar Ultraviolet Imaging Telescope (SUIT)
  3. Solar Low Energy X­ray Spectrometer (SoLEXS)
  4. High Energy L1 Orbiting X­ray Spectrometer (HEL1OS)
  5. Aditya Solar wind Particle Experiment (ASPEX)
  6. Plasma Analyser Package For Aditya (PAPA) 
  7. Advanced Triaxial High Resolution Digital Magnetometers.

Advantages of L1 point

  • Continuously viewing the sun without any occultation/eclipses. 
  • Help in observing the solar activities and its effect on space weather in real time.
