ARIES facility (Aryabhata Research Institute for Observational Sciences) will host the support center for the Aditya-L1 mission, which is due to be launched in 2022. ARIES is an autonomous institute under the Department of Science & Technology and is located in Nainital (Uttarakhand).

Aditya-L1 Mission

  • It is India’s first scientific expedition to study the Sun.
  • 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 Mission 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 space weather.

Challenges in Launching the Mission

  • The huge distance between Sun and Earth poses a scientific challenge.
  • Aditya L1 will have some moving components which increases the risks of collision.
  • Other issues are the super hot temperatures and radiation in the solar atmosphere.

Why is it important to study the Sun?

  • Every planet, including Earth and the exoplanets beyond the Solar System, evolves and this evolution is governed by its parent star. Sun affects the weather of the entire system.
  • Variations in this weather can change the orbits of satellites or shorten their lives, interfere with or damage onboard electronics, and cause power blackouts and other disturbances on Earth.
  • To learn about and track Earth-directed storms, and to predict their impact, continuous solar observations are needed.
