U.F.O

U.F.O:

 U.F.O is generally termed as Unidentified Flying object
The flying object which comes across the sky no one can identify its properties,base and from the point where it had came from.in its general definition, is any apparent anomaly in the sky that is not identifiable as a known object or phenomenon.

The U.F.O's comes rarely which are seen in many countries in the world.

Many scientists,researchers,physicists calculated that the U.F.O's are not from our planet they may came from outer space/world.At rare moments some people captured the pics/video of the U.F.O's after seeing/analizing the images/videos the researches came to assumption that most of the U.F.O's are discs shaped flying objetcs.
The main features which need to be noted regarding U.F.O's
1.The U.F.O are fast they may be seen by humans for some time only since they dissapear quickly
2.Some believe that aliens are inside the U.F.O's and may be invading the earth its just an contradiction not proved at all
3.U.F.O has advanced digital/mechanical/computerised technology

SPACE TECHNOLOGY

SPACE TECHNOLOGY:

In todays world the technology advanced rapidly.Technology is the revolution which was introduced by human being through the development of machines,devices and so on.
In simple terms technology refers to machinery and devices developed from scientific knowledge (or) the application of scientific knowledge for practical purposes,especially in industries.Engineering is the discipline that seeks to study and design new technologies.    

              Technology=Development+Modification+Improvement from computer machines to nano devices

Space Technology is the advancement of technology in the field of Astro Physics,Rocketry and Space travel.
Every human being in the world need to know how space technology is useful.
The main source for human beings from planet earth is water not only water even food n shelter are also important to survive.No one knows what happens at what second from natural disasters like Earth quakes,Tsunami and due to earths climatic conditions with polluted vehicles/factories the ozone layer is affecting,the ultraviolet rays are directly falling on the earths surfaces which increases the temperature where the deep freeze antarctica and atlantic oceans are melting slowly if these cold ice oceanic regions melts the whole earth may be sinked with water.so to prevent these we need to take lot of preventive steps 
we need to avoid the pollution by preventive measures,
we need to plant more trees(afforestation)

After all these measures keeping aside we need to take ahead step in the space technology
At present the man can travel to space/moon, but cannot be able to travel to mars and come back since that much advancement in technology is not there.The mars is been a co-planet to earth or nearest planet to earth the human being should reach the planet mars n need to study/analize/and need to set up a base for sheltering all the human beings before the planet earth has some disasters.
The technology in rockets/computer devices has to be improved logically.
At present a satellite is upto the mark to reach the planet mars with great technology n effort then when the humans will reach???     

SPACE SHIP

SPACE SHIP:The vehicle which is used to travel in space from one planet to another planet without measuring distance parameters.The space ships are normally seen in fictional movies like star wars.Space shuttle is different from Spaceship.

Space ship varies in size,shape and weight.According to ancient astronomy Space ships are the transporting vehicles for humans from one planet to other planet.Their are various sources through which these space ship runs.In NASA as far as concerned the designing of shuttles are done till to travel the planet mars that too with huge technology.Years of travel is done in space ship to reach one planet to other.The persons who are travelling in these space ships must store food in space ship for the time that is taken to travel
