Aditya-L1 Mission : Important Points

Aditya-L1 Mission:

ARIES facility (Aryabhata Research Institute for Observational Sciences) will host the support center for Aditya-L1 mission, which is due to be launched next year (2022).

  • ARIES is an autonomous institute under the Department of Science & Technology and is located in Nainital (Uttarakhand).

About Aditya-L1 Mission:

  • It is India’s first scientific expedition to study the Sun. It will be ISRO’s(Indian Space Research Organisation) second space-based astronomy mission after AstroSat, which was launched in 2015.
  • ISRO categorises Aditya L1 as a 400 kg-class satellite that will be launched using the Polar Satellite Launch Vehicle (PSLV) in XL configuration.
  • It will be inserted in a halo orbit around the L1 ( Lagrangian point 1), which is 1.5 million km from the Earth.
  • The space-based observatory will have seven payloads (instruments) on board to study the Sun’s corona, solar emissions, solar winds and flares, and Coronal Mass Ejections (CMEs), and will carry out round-the-clock imaging of the Sun.

Aditya-L1 Support Centre (ASC):

  • The main aim of this center is to let every researcher in India perform analysis over scientific data obtained from Aditya-L1.
  • It will expand the visibility of Aditya-L1 beyond India at the international level.
  • It will host a compendium of the location and duration of different features on the solar surface such as coronal holes, prominences, flares, CMEs, and sunspots.
  • Continuous monitoring of the location and duration of these features will help in monitoring the Earth-directed CMEs and thereby, the space weather.
