Space Travel
 

Throughout history, man has dreamed of space travel, but it has only been within the last century that this dream has come true. The history of new space travel began with rockets developed throughout globe battle II. After WWII, lots of the scientists who worked on martial projects adapted their rockets for space travel. The timeline of space travel developments sustained through the Cold War. An institute called NASA was formed in the U.S.A. to expand the technology for space travel.

The first space traveller was an animal - a monkey sent into space. The first experiment in space travel went a long way towards sympathetic the medical dangers involved. As space is a vacuum, space travellers have to carry their own oxygen with them. Radiation is also a medical risk, and requires protecting to be built into the boat and space suits. Also, because there is no gravity in space, space travellers' food is usually kept in semi-liquid form inside of bags to prevent it from flying all over the interior of the spaceship.

Why is space travel significant? First, it is significant because it allows us to search and skill more of our universe. Technology is also developed for space travel that later becomes practical for applications here on globe, and the funding that goes into space searching helps development in the sciences.

In the future, space travel will become increasingly reasonable. Space travel will be obtainable to normal people as well as particularly trained astronauts and the rich. Before space travel reaches that stage of sophistication, but, some technological problems need to be conquered. Rocket based launch can be unsafe - if there is a mishap during the open it is very hard to get well, as evidenced by the contestant Space Shuttle tragedy.

Luckily, a new type of space travel is now being urbanized by private companies that uses airplane technology to attain a high altitude, and then activates rockets to go the rest of the way. This considerably cuts down on the risk. As this technology becomes easier to construct and more reliable, space travel will be obtainable for tourists. Inside our lifetimes, we might all obtain to enjoy the wonders of space first-hand.
