10 Lines on Satellite in English 

A satellite is a man-made object that orbits the Earth, or another celestial body.

Satellites can be used for a variety of purposes such as communication, navigation, and weather forecasting.

The first artificial satellite, Sputnik 1, was launched by the Soviet Union in 1957.

There are two main types of satellites: geostationary and low Earth orbit (LEO) satellites.

Geostationary satellites orbit at an altitude of about 36,000 kilometres and remain in a fixed position relative to the Earth.

Many countries have their own satellite program, including the United States, Russia, China, and India.

Satellites are also used for scientific research, such as studying the effects of climate change and monitoring the health of the planet.

Some companies are planning to launch large constellations of satellites to provide internet access to remote and underserved areas.

As technology continues to improve, the use of satellites is expected to increase in a variety of fields such as agriculture, transportation, and security. 

Satellites are typically launched into space using a rocket.

They are equipped with solar panels to generate power and instruments to carry out their specific mission.

Some military and intelligence agencies use satellites for surveillance and reconnaissance.

Satellites are also used in GPS (Global Positioning System) navigation, allowing devices such as smartphones to determine their location.

Some satellites can change their orbit, known as “orbital manoeuvring”, which allows them to perform multiple tasks.

The lifespan of a satellite varies depending on its mission and design, but many are designed to operate for several years.

After the end of their operational life, satellites can become space debris and pose a potential threat to other satellites and spacecraft.

International agreements and regulations exist to minimize the creation of space debris and ensure the safe operation of satellites.

The cost of launching and operating a satellite can vary greatly depending on the mission and size of the satellite, with some costing billions of dollars.
