Space Shuttles

By Key Lockx  

Intro

       Have you every imagined that you had 450 billion dollars?  What would you do with it?  Well NASA would use it to launch a space shuttle because launching space shuttles help them so much- itŐs incredible!  In this report, you will learn what they do, its history, and how it works.  Enjoy.=

~What they do~

Space shuttles can do so much!  One of the things that they do is carry cargo and people to space stations and back to earth, according to Ňlibrarythinkquest.Ó  But not only that but the astronauts even get to do experiments on the space shuttle, which is quite unusual.  They send out satellites for many uses, so we can use them down on earth.  But whatŐs even cooler is that they are reusable.   Part of the space shuttle stays intact and returns to earth, while the other half goes out into space.   It is totally amazing!  ItŐs out of this world!

 

History

 

    Almost 20 years ago, in 1981, they had officially finished the space shuttle.  NASA had been working on it for sometime, so it was luckily finished.  Then on April 12, in 1981, the first space shuttle, The Space Shuttle Columbia, became the very first space shuttle launched.  The space shuttle was flown by Commander John W. Young, and Pilot Robert L. Crippen.   This is all according to NASA.gov.   Also, recently this year, we celebrated what is called Yuri Gagarin.  The reason why itŐs called that is because Yuri Gagarin was the first human in space.   So that is why, this year, we celebrated ´uri Gagarin.

 

 

How it works?

How the space shuttle works is interesting.  Pretty much like any other object in low Earth orbit, a space shuttle must reach speeds of about 17,500 miles per hour to remain in orbit.  Each of the two solid rocket boosters on the shuttle carries more than one million lbs. of solid propellant.  The shuttles large external tank is filled with more than 500,000 gallons of super cold liquid oxygen and liquid hydrogen, which are mixed and burned together to form the fuel for the shuttles three main rocket engines.   The main weight is about 25 tons unmanned, and the cost per trip is about 450 million dollars.  This is all told on NASA.gov FAQ.

Conclusion

In conclusion, I hope you now know a whole lot more about space shuttles and why they are so great.  They help us in many more ways than I mentioned, it is so amazing!  They arenŐt just used for cargo carrying but they are used for lots more, and these only some of the great things about them and what they do.
