Archives (PRELIMS & MAINS Focus) LIGO-India Syllabus Prelims –Science and Technology Context: Prime Minister Narendra Modi recently, laid down the foundation stone of LIGO-India on the occasion of National Technology Day. About LIGO-India:- IMAGE SOURCE: Gravitational waves discovery: India’s imprint in landmark LIGO project – Times of India (indiatimes.com) LIGO is the world’s most powerful observatory. It exploits the physical properties of light and space to detect and understand the origins of gravitational waves. At the moment, there are two such observatories in the US. These are separated by a distance of 3000 kilometres that work in tandem to pick up these gravitational waves. Each LIGO detector consists of two arms. LIGO-India will be the fifth node of this international network of gravitational wave observatories. It will be located in Maharashtra, India. It is envisaged as a collaborative project between a consortium of Indian research institutions and the LIGO Laboratory in the USA, along with its international partners. It will be built by the Department of Atomic Energy and the Department of Science and Technology, with a memorandum of understanding (MoU) with the National Science Foundation, the US, along with several national and international research and academic institutions. LIGO-India is a collaboration between the LIGO Laboratory (operated by Caltech and MIT in the US) and three Institutes in India namely:- the Raja Ramanna Center for Advanced Technology (RRCAT, in Indore), the Institute for Plasma Research (IPR in Ahmedabad), and the Inter-University Centre for Astronomy and Astrophysics (IUCAA, in Pune). When LIGO-India is completed, it will join a global network of gravitational-wave observatories that includes Virgo in Italy and KAGRA in Japan. Significance:- LIGO-India will provide opportunities for Indian youth to pursue research careers in cutting-edge areas of science and technology. It will lead to advancement in gravitational-wave astronomy and astrophysics. It will lead to the development of cutting-edge technologies.(UPSC MAINS: Privatisation in Space Sector) Gravitational Waves:- A gravitational wave is an invisible (yet incredibly fast) ripple in space. (UPSC MAINS: Gravitational waves) They travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by. Einstein predicted that when two bodies such as planets or stars orbit each other it causes ripples in space. These ripples would spread out like the ripples in a pond when a stone is tossed in. Scientists call these ripples of space gravitational waves.

(2022) A hypersonic missile is launched into space to counter the asteroid approaching the Earth and explode it in space. A spacecraft lands on another planet after making several orbital motions. A missile is put into a stable orbit around the Earth and deorbits over a target on the Earth. A spacecraft moves along a comet with the same surface. speed and places a probe on it. Q.2) If a major solar storm (solar flare) reaches the Earth, which of the following are the possible effects on the Earth? (2022) GPS and navigation systems could fail. Tsunamis could occur in equatorial regions. Power grids could be damaged. Intense auroras could occur over much of the Earth. Forest fires could take place over much of the planet. Orbits of the satellites could be disturbed. Shortwave radio communication of the aircraft flying over polar regions could be interrupted.
