Exciting satellite information

The world of satellites is an exciting and mysterious world for many people who are not specialized in space science, satellites have many different types and orbital trajectories that orbit them, and satellite speeds vary from mission to mission, if you are interested in learning more about satellites follow us with this topic to discover the most important information about satellites

 Satellite information:

  • Satellites are artificial objects that are deliberately sent into their orbits in space, and generally send satellites to send, receive or bounce information in different parts of the Earth.
  • Satellites are artificial objects, different from natural satellites such as the moon orbiting the Earth, and also different from planets like the Earth itself orbiting around the Sun.
  • Satellites generally go into space with rocket-propelled grenades to reach their orbits in space.
  • In October 1957, the Soviet Union launched Sputnik 1, the first satellite in the world to be launched into space.
  • This previous satellite launch event led to the beginning of the space race between the Soviet Union and the United States, which lasted many years.
  • The Sputnik 2 II satellite was launched in November 1957 by the Soviet Union, which had put the first living creature in space into orbit and was a dog named Leica.

Only three months after the Soviet Union launched its first successful satellite in space, the United States of America launched its first satellite, Explorer 1, in January 1958.

Since the launch of the first satellite in 1957, more than 6,500 satellites have been put into space orbit (as of October 2010), about 3,600 of these satellites are still in orbit, and about 1,000 satellites are still operational, while the others are still operational, while the others are still operational. It is now classified as space debris.

The International Space Station (ISS) is currently the largest satellite in orbit around the Earth.

  • There are 3 main sets of satellites, there are fixed satellites that handle the transfer of billions of voice and video data, mobile satellites used in navigation, connecting remote ships, aircraft and others, and research satellites Scientific meteorological data, Earth survey images and other scientific research functions.
  • Geostationary satellites rotate from west to east over the equator, moving in the same direction and at the same speed as the Earth rotates, so that these satellites do not appear to move relative to the Earth.
  • Polar orbiting satellites orbit the Earth north and south from one pole to the other, so that the Earth orbits under these satellites examining the entire Earth sector.
  • The Low Earth Orbit (LEO) is located at an altitude of 2000 km from the Earth’s surface and has about 500 active satellites.

The medium Earth orbit (MEO) is higher than the LEO and is located at an altitude of 35,786 km from the Earth’s surface, with 50 active satellites.

– High Earth Orbit (HEO), which is more than 35,786 km from the Earth’s surface and has 400 active satellites.

The two main components of satellites are the power of air to send and receive information, and an energy source such as solar panels or batteries.

The speed at which satellites have to move to stay in space is called the orbital speed, generally requiring more than 17,500 miles per hour (28,200 km/h).

As more satellites are launched, the risk of crashes increases and, in 2009, two communication satellites collided in space, one American and one Russian.
