It is no more news that the earth is enveloped by many gases in a part commonly referred to as the atmosphere. However, it has also been discovered that beyond the atmosphere, there is a portion of space or atmosphere that does not contain any gas at all.
Space travel, also commonly known as Space exploration is said to be the discovery and exploration of celestial bodies in the outer space orbit with the help of the ever evolving and advancing space technology. Despite the fact that the study of outer space is carried out mostly by astronomers with the use of telescopes, the physical exploration of space is often done with the aid of unmanned space probes and human space flight.
Today there are many space travel corporations in the world and they can be private or public. The space travel public organizations include Roscosmos, The China National Space Administration and NASA and Private space travel organizations including Lockheed Martin, Boeing and Space X. Space X, a space travel organization founded by Elon Musk is considered to be one of the best and most popular Space travel company in the world.
A lot of public and private organizations has shown interest in researches to establish the importance of permanent colonization of Mars and the long-term habitation of human on the planet Mars. The organizations that have shown interest in Mars colonization include public organization such as Roscosmos, The China National Space Administration and NASA and Private organizations such as Lockheed Martin, Boeing and Space X.
For now, there are three methods of Space travel that have been discovered. The first method is the one that involves the use of balloons to travel to space, but this method is not effective as the balloons cannot go very high.
The second method is that of rocket launching whether manned or unmanned. Rocket launching is considered to be the best and the most efficient method of traveling to space in present times. These rockets are often designed with several sections or stages that are capable of being released after its fuel has been used up in order to decrease the total weight of the ascending rocket.
Satellite launching is the third method of space travel and it involves taking satellites which are metallic spheres that often contain different instruments to space. However, satellite launching is different from the other method of space travel because of the fact that it cannot be launched into space on its own but with the aid of rockets that puts them in the desired orbit. Some of these satellites are often sent to space to travel around the earth like artificial satellites.
What we are going to see in the near future is increased activity in all areas of Space Travel.
