Coastal surveillance radars are critical components of India's Maritime Domain Awareness (MDA) framework to secure its vast coastline.

The system is designed to detect small targets and enhance situational awareness along the coastline to prevent unauthorized intrusions.

The Defence Research and Development Organisation (DRDO) is responsible for developing indigenous defense technologies, including coastal surveillance systems.

Vajra Prahar is specifically an Army-to-Army exercise involving special forces units.

The exercise focuses on enhancing interoperability and sharing tactical expertise between the special forces of both nations.

Vajra Prahar is a recurring joint special forces exercise between the Indian Army and the United States Army.

ISRO's Mars Orbiter Mission (MOM-1) made India the first Asian nation to successfully reach Mars orbit and the first country in the world to achieve this feat in its very first attempt. This demonstrated ISRO's cost-effective and efficient approach to deep-space missions, setting a precedent for future missions like Mangalyaan-3.

While specific details for Mangalyaan-3 (MOM-2) are still under development, ISRO has indicated plans for more advanced scientific instruments and objectives, potentially including a lander/rover component or more detailed studies of Martian geology, atmosphere, and the search for biosignatures, building on the orbiter-only mission of Mangalyaan-1. Human missions and sample returns are far more complex and likely for later stages.

Mangalyaan, officially known as the Mars Orbiter Mission (MOM), was ISRO's first successful interplanetary mission to Mars, launched in 2013. Its success demonstrated India's capability in deep-space exploration and laid the groundwork for subsequent missions like the planned Mangalyaan-3.

A PLI scheme for green energy components would focus on incentivizing the manufacturing of parts used in renewable energy technologies like solar panels and wind turbines.
