Agni-P (Agni-Prime) is a new generation advanced variant of the Agni class of missiles, featuring canisterization and improved accuracy.

The Varuna naval exercise series between India and France was initiated in 1993 and was later christened 'Varuna' in 2001.

The exercise aims to strengthen the strategic partnership and improve interoperability between the two navies in the maritime domain.

Varuna is a long-standing bilateral naval exercise conducted between the Indian Navy and the French Navy.

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.

The LIGO-India gravitational wave observatory is being constructed in Aundha Nagnath, Hingoli district, Maharashtra. This site was selected for its seismic stability and isolation from human-made noise.

The integrated test of ISRO's 2000 kN thrust semi-cryogenic engine (SCE-200) was successfully conducted at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu. This facility is dedicated to the testing and qualification of liquid and cryogenic propulsion systems.

The semi-cryogenic engine is a critical component for the first stage of ISRO's Next Generation Launch Vehicle (NGLV). The NGLV is envisioned as a heavy-lift, reusable launch vehicle designed to reduce launch costs and enhance India's access to space.

ISRO's semi-cryogenic engine, specifically the SCE-200, is designed to use Liquid Oxygen (LOX) as the oxidizer and Kerosene (RP-1) as the fuel. This combination offers higher thrust and is more cost-effective compared to traditional cryogenic fuels like liquid hydrogen.
