Fusion energy is considered a highly desirable future energy source due to its abundant fuel, minimal environmental impact, and inherent safety features compared to fission.

ITER involves the participation of 35 nations, making it one of the largest and most significant international scientific collaborations in history.

These powerful magnets create a magnetic field that holds the extremely hot plasma away from the reactor walls, preventing damage and maintaining the conditions for fusion.

Fusion involves combining light atomic nuclei, such as isotopes of hydrogen, to release energy, mimicking the process in stars.

ITER is designed to prove that fusion can be a viable and scalable source of energy, not just a scientific experiment.

While stealth can be a factor, the primary challenge posed by hypersonic missiles is their ability to maneuver unpredictably while traveling at extreme speeds, making interception difficult.

The successful indigenous development and testing of a complex weapon system like Agni-VI demonstrates India's growing self-reliance and capability in its defense manufacturing sector.

Possessing advanced offensive missile capabilities like Agni-VI strengthens a nation's strategic deterrence, its ability to prevent conflict through the threat of retaliation.

The combination of very high speeds and the ability to change direction mid-flight makes hypersonic missiles extremely difficult for current missile defense systems to track and intercept.

Hypersonic missiles are defined as those capable of traveling at speeds greater than Mach 5, which is five times the speed of sound.
