News: India to participate in the international mega science project SKA

 

What's in the news?

       The Government of India has accorded its approval for India’s participation in the international mega science project, Square Kilometer Array (SKA), at an estimated cost of ₹ 1250 Cr.

 

Key takeaways:

       This approval covers funding support for the construction phase of the international SKA Observatory (SKAO) spread over the next 7 years.

       The project will be jointly funded by the Department of Atomic Energy (DAE) and Department of Science and Technology (DST), with DAE as the lead agency.

       The Indian participation in SKA is a truly nationwide, inclusive project led by a consortium of more than 20 academic and research institutes (with NCRA-TIFR as the nodal institute).

 

Square Kilometre Array (SKA) Project:

       It is an international effort to build the world’s largest radio telescope.

       Once constructed, the SKA will be the most powerful radio telescope ever built, capable of detecting faint radio signals from extreme distances, with eventually over a square kilometre (one million square metres) of collecting area.

 

Location:

       It is not a single telescope. It consists of an array of antennas strategically designed and set up in South Africa and Australia.

       South Africa – host high and mid-frequency dish antennas (between 350 MHz and 15.4 GHz).

       Australia – Low-frequency antennas (between 50-350 MHz).

 

Goals:

       To study the universe and its evolution, origin and evolution of cosmic magnetism and dark energy and evolution of galaxies.

       To detect very weak extra-terrestrial signals and search for molecules that support life.

 

Collaborative efforts:

       It will also be one of the world’s largest collaborative research projects, involving thousands of researchers and the world’s fastest supercomputers.

 

Square Kilometre Array Observatory:

       Founded in 2019, the Square Kilometre Array Observatory (SKAO) has 16 consortium members — Australia, South Africa, Canada, China, India, Japan, South Korea, the UK, Spain, Portugal, Switzerland, France, Germany, the Netherlands, Sweden, and Italy.

 

Headquarters: Jodrell Bank Observatory in the UK.

 

India's Contribution:

       The Indian research partner for the SKA project is Pune’s Giant Metrewave Radio Telescope, operated by the National Centre for Radio Astrophysics (NCRA) of Tata Institute of Fundamental Research (TIFR).

       India’s main contribution to the SKA is in the development, and operation, of the Telescope Manager element, the “neural network” or the software that will make the telescope work.
