Satellites have greatly improved human civilization through applications in communication, automation, traffic monitoring, and responding to natural disasters. There are different types of satellites that serve various purposes, including weather satellites that aid weather forecasting and disaster response, reconnaissance satellites that observe enemy movements, navigational satellites that enable GPS, and communication satellites that facilitate radio, TV, and internet applications. While satellites currently improve many aspects of life, there is a possibility that in the future they could also be hacked and used to control humanity.
2. Satellites and their uses
In the 21st century ,Human Civilisation has achieved so much progress in
the field of Science and Technology . Artificial Satellite is one of them .
With the help of these artificial satellites human being is benefited in
every phase of our life like communication , automation , tracking
traffic , dealing with natural calamities . For this we have different types
of artificial satellites . They are Weather Satellite , Tether Satellite ,
Reconnaissance Satellite , Killer Satellite , Navigational Satellite , Earth
Observational Satellite , Communication Satellite and Astronomical
Satellite.
3. Different Sizes Of Satellites
Size - wise satellites are divided into various categories like the Pico, Nano,
Micro, Mini and normal Satellites.
4. Weather
Satellite-
These satellites are used to
monitor and record Earth’s
climate and weather . It helps us
to displace people at the time of
cyclone , hurricane , tsunami and
weather forecasting .
5. Tether Satellite-
• These satellites are mainly used
for altitude control , stabilization
and maintaining relative positions
of a larger spacecraft sensor
system.
6. Reconnaissance Satellite-
These satellites are designed to observe the Earth for military purposes . It is used to keep an eye on enemy
movement .That is why it is called as ‘the Spy Satellite’ . Killer satellites are used to destroy war heads from enemy
countries.

7. Navigational
Satellite-
• These satellites help in aircraft ,
ship and vessel movement . These
allow small electronic receivers to
determine elevation latitude ,
altitude and longitudinal location .
They help in formation of GPS
system.

9. Astronomical
Satellite-
•These satellites are used for the
observation of distant planets and
galaxies including other outer space
objects . They are known as space
telescopes or space observatory .
10. Conclusion:
So our life is improved so much by the benefits of the
artificial satellites. Day will come when Satellite will control
our life. It may be possible as some aliens may hack these
satellites and control us too.
