Significance of Satellites

Significance of Satellites Introduction

Significance of Satellites an object which revolves around the planet in a circular motion is known as Satellite. All the satellites revolves around the orbits. Except our moon, all other satellites made by humans are called artificial satellites.For example, the first artificial satellite called Sputnik 1 by Soviet Union was launched on 4 October,1957 . Whereas, moon is the natural satellite of Earth planet.

Satellites

Satellites play a pivotal role in Science, Information Technology, Engineering, and Many other fields.Satellites are called semi-independent computer controlled systems.

Functions Of Satellites

Different Satellites have different types of jobs. In other words, there is a difference between the satellite of television, and weather. It means, there is a separate satellite for producing television signals for instance the satellite which performs tasks of a weather station.Followings are some major functions of Satellites:

1)Satellites provide all types of signals, such as, Radio, Television, Global Positioning System (GPS), and Weather Signals.
2)Observes and measures the environment from long distances, and help in monitoring important resources. Such as Remote Sensing or Earth observational Satellites.
3) The Satellites such as Weather and Climate Satellites help in predicting the weather conditions. COSMOS is one of the typical satellite which help meteorologists to check out the weather conditions.
3) Communication Satellites are functional through antennas. Ground stations transmit signals and the satellite antennas pick up those signals so that to transmit data on Earth.

TELSTAR and INTELSAT are the examples of Communication Satellites. These satellites are being used in to produce telephone, radio, and television signals all around the world.
4) Military of the sovereign nations also use satellites to remain powerful in saving secret information. The military use powerful applications in this regard, such as Photographing equipment and high technical electronics.
5)A big telescope termed as an Astronomy Satellite floating in the space work as infrared imaging equipment.
There are so many other Satellites besides Weather, Communication, Astronomical, Remote-sensing, and Military Satellites. Most importantly, Navigational Satellites are helping Satellites in locating motions, movements, locations, internet, and Information about the space.

Important Points

✓ Mostly, Satellites launch into space on rockets.
✓Satellites signals produce by methods such as, carrier waves, frequencies, and amplitudes.
✓Mostly, satellites signals do not require instructions of the user, but automatically deliver signals where ever they require.
✓Satellites orbit around planets, on different speed and different frequencies. Orbits such as, geostationary and polar.
✓Moon is the natural Satellite.

✓First man-made Satellite was produce by Soviet Union in 1957.
✓In lower earth orbits, there are about 500 operational satellites.
✓In medium earth orbits about 50 satellites are working.

Significance of Satellites Conclusion

A satellite is an object to receive signals from space and to perform various tasks by the help of those signals and waves.
Satellites are of two types: Natural, just as Moon and Artificial such as made by human beings for the purpose of various tasks. The significance of satellites is more important in our globe. Because, they help in to achieve all scientific, technology, and electronics objectives.

Latest Scientific Discoveries

Latest Scientific discoveries

Science is progressing by leaps and bounds in almost all of its major fields like physics, chemistry and biology. Latest Scientific Discoveries like sole reason for this rapid progress is the contribution of technology in above-mentioned fields. Latest approaches of modern scientists are to make life easier and fast. However, the consequences of such approaches are the destruction of natural reservoirs that leads to an increase in individual stress level. Despite more scientific convenient lifestyle, the hard fact is that life is now full of anxiety.

Metallurgy was probably little known branch once but today with technological advancements it is one of the most researched branches. Aluminum Alloy discovery is a landmark in this field.
Solar energy is also great accomplishment of modern physics.

Draw Backs of Modern Scientific Accomplishments.

Stephen Hawkins claims that the chances of disaster on planet Earth are rising to a near certainty as the progress in science and technology tend to be greater threat to our existence For instance, we drive away from natural lifestyle to anti social modern luxurious lifestyle Consequently, man is now more anti social, less communicative and highly anxious.
Loads of unnecessary information, IT progress is making him less conscious to his natural habitats.
All in all, we cannot stop science from progressing but it efforts do to make scientific approaches more eco friendly. In to this way, environment could be saved

Physical Science Fields Scope Principles

Physical Science

The physical science which is a field that deals with many disciplines such as earth and its components, rocks and soil, the ocean and the atmosphere. In short, it is the systematic study of the inorganic world. That is, it does not study living things.

Fields of Physical Science

1. Astronomy

To clarify it is the study of celestial objects {stars, galaxies, planets, moons and asteroids}, the physics, chemistry. So some natural processes that occur outside the atmosphere of Earth including some explosions, gamma ray bursts and cosmic radiations.

2. Chemistry

Therefore It is the study of structure, properties and change of matter. But It deals with properties of atoms that observe the manner in which atoms form chemical bonds when they form compounds, the interaction of different substances that form matter through inter molecular forces and the interactions of substances that form substances through chemical reactions.

3. Geology

Firstly it is the study of composition, physical properties and the history of Earths components.
4. Physics:
Secondly it involves the study of matter and its motion through space and the concepts of energy and force. It also observes the phenomenon how the nature works.

5. Atmospheric science

Hence It is the study of atmosphere, the processes that take place in it and the interactions with other systems. It also involves the study of climatic changes and tropical cyclone activity using different equipment.

6. Oceanography

In case of It is the study of physical and biological aspects of the ocean.

7. Earth sciences

Finally It is the field of science that deals with planet Earth. It involves the study of the working of natural environment and it includes the study of hydrosphere, atmosphere, lithosphere and biosphere.

History of Physical Science

During Talking about the history of physical science, we come to know that the Italian mathematician, astronomer and physicist, Galileo Galilei, was the first to develop the concept of physical science by his empirical experiments, astronomical discoveries and his improvement of telescope.

Principles of Physical Science

Moreover, research shows that physical science has three main principles:
1. Firstly, it describes and measures motion, Newton’s laws of motion, forces, weight, mass, momentum and conservation of momentum.
2. Secondly, it describes the Theory of Gravity.
