What is an important function of communication satellites?

• A. Facilitate global communications and broadcasting
• B. Conduct scientific experiments on other planets
• C. Track the movement of asteroids
• D. Control space debris around Earth

Answer: (A)

Communication satellites play a crucial role in facilitating global communications and broadcasting. They are strategically placed in orbit to transmit and receive signals over vast distances, enabling telephone calls, television broadcasts, internet services, and emergency communications. These satellites serve as relay points, allowing signals from one location to be sent to another, often across different continents, effectively bridging gaps in communication infrastructure on Earth.

The other options describe functions that are not primary to communication satellites. While conducting scientific experiments on other planets, tracking the movement of asteroids, and controlling space debris involve important activities within space research and oversight, they are typically not the responsibilities of communication satellites. Instead, these tasks are handled by dedicated scientific missions, space observatories, or other specialized spacecraft designed for those specific purposes.
