Science & Technology MCQs

India's nuclear triad consists of land-based ballistic missiles (like Agni-V), submarine-launched ballistic missiles, and nuclear-powered submarines capable of launching ballistic missiles. Air-launched cruise missiles are not typically considered part of the triad.

The Agni-V is a surface-to-surface, intercontinental ballistic missile with a range of over 5,000 km, capable of carrying a nuclear warhead.

The lunar south pole is of significant scientific interest due to the presence of permanently shadowed regions that are believed to harbor substantial amounts of water ice and other volatile compounds, crucial for future lunar habitation and resource utilization. Chandrayaan-4 is expected to further explore these resources.

The Chandrayaan-4 mission, like its predecessor Chandrayaan-3, is specifically targeting the lunar south pole due to its potential for water ice and other valuable resources in permanently shadowed regions.

The Chandrayaan-4 mission is being planned for a landing on the lunar south pole by the year 2028, building upon the successes of previous Chandrayaan missions and focusing on advanced lunar exploration.

LIGO-India is a collaboration between a consortium of Indian research institutions (like RRCAT, IUCAA, IPR) and the LIGO Laboratory in the USA, which is operated by Caltech and MIT with funding from the National Science Foundation (NSF).

LIGO-India's primary objective is to detect gravitational waves, which are ripples in spacetime caused by extremely energetic cosmic events such as the merger of black holes or neutron stars. It will join the global network of LIGO observatories to enhance detection capabilities.
