Unlocking the Secrets of Artificial Satellites: 10 Facts You Never Knew
Artificial satellites are objects that orbit Earth or other celestial bodies.
They're used for communication, navigation, weather forecasting, and scientific research.
The Soviet Union launched Sputnik 1, the first man-made satellite in 1957.
Launch vehicles send satellites into orbit, while Earth's gravity maintains them there.
They use solar panels, batteries, and computers to function.
Satellites come in four basic categories: scientific, meteorological, communication, and navigation.
In addition to communication and navigation, satellites are used for security, scientific research, and weather forecasting.
They also have some challenges, such as cost, collisions, and surveillance.
With fresh developments in technology and potential uses, satellites have a promising future.
