ADITYA-L1

About:

• Objective: The probe named Aditya-L1 will be sent by PSLV-XL from Sriharikota to observe the solar corona, the outer layers of the Sun.
  
  
• Its main payload is Visible Emission Line Coronagraph (VELC) which will study the diagnostic parameters of solar corona and dynamics and origin of Coronal Mass Ejections (3 visible and 1 Infra-Red channels).
  
  
• Features: It will be inserted in a halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system, which is 1.5 million km from the Earth.
  
  
• Significance of Mission:
  • A Satellite placed in the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system has the major advantage of continuously viewing the Sun without any eclipses.
    
    
  • Only NASA and ESA have successfully placed satellites at the L1 point as of date.
    
    
  • This will be the first Indian space mission to study the Sun.
    
    
  • It will be India’s third big extra-terrestrial outing after Moon and Mars.
