India’s first mission to study the Sun will be launched by June-July

In News
  • The Indian Space Research Organisation (ISRO) is planning to launch the Aditya-L1 mission by June or July this year. Aditya-L1 is the first Indian space mission to observe the Sun and the solar corona.
Aditya-L1 Mission
  • The Aditya spacecraft will study solar magnetic storms and the impact of the solar atmosphere on the earth.
  • The mission will study -
  • Solar Winds: These winds are created due to the expansion of the sun’s plasma
  • Photosphere and Chromosphere of the sun
  • Corona of the sun
  • Energetic particles of the sun
  • The outermost layer of the sun is called Corona. The corona has ionized plasma.
  • These ions carry magnetic fields around them. This makes the corona magnetic.
  • The study of the magnetic field in the corona of the sun is called coronal magnetometry
  • The Aditya-L1 satellite will have 40 different optical elements and an internally-occulted coronagraph that will reduce the scattering of Sun’s powerful light to a bare minimum.
  • Also, a super-polished mirror built by ISRO will help the satellite image the solar corona down to as close as 1.05 Ro, starting from 1.05 times the solar radius.
  • The 90-kg visible line emission coronagraph (VERC) is one of the most important payloads, which will now be integrated into Aditya L1 satellite.
