In his 'Mann ki Baat' programme of AIR, Prime Minister Narendra Modi has said that ISRO is planning to launch a satellite called Aditya to study the sun.
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.
