Space Travel
There are no limits to man’s curiosity. The human race has explored not only the Earth but also the space which blankets our world. This exploration had started off with telescopes and other technical stuff and now human beings have traveled through space to find out more about it. Rocket science is becoming a better known subject to the world with each passing day and thus Space Travel becomes more possible.

Space travel is done for a lot of reasons. Military space travel is done basically for security reasons. The scientists do it for entirely different purposes. The astronauts from NASA carry their travel space bag and go out there to know the true nature of the outer space. Space travel NASA expeditions are highly sophisticated and scientific in nature.

History of space travel shows us that even man from the earliest ages was interested in space travel. Space travel timeline if sketched show us an inch by inch movement towards successful space flights. Our race has come from the stage where geniuses of the era wanted to fly in the air to know how birds do that to highly sophisticated expeditions to set foot on the moon. Future space travel will even bring you to farther places. The frequency of space travel will also increase.

Space travel is not like traveling on the Earth. There are a number of medical dangers in space travel. If the vehicle has a minor flaw it can prove fatal. The change in air pressure can be damaging. Space travel history tells us about some accidents in which people lost their lives. Such problems with space travel do not allow us to open it for general public as yet. That is why tourist space travel is still not possible. Even for the few who can afford it, they have to go through some training if they are sent to explore the space.

Now the question is, with all the dangers associated with it, why space travel is important to us? This type of travel helps us to know our world in a much better way and improve our world accordingly.
