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).
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.
