Mechanical engineering and space traveling

I have an introduction of my eassy. 

What I need .. just 3 body paragrph and conclusion. 

-I want evrything  done after 3 to 4 hours.  

all the essay should cover 5 pages and I have the resources. 

 The most important thing is - the writer should be able to make his writing very clear and simple. Because my english is poor a little bit.
