The 21st century witnesses the flourishing of space science and technology. More and more countries have come to realize the need for international cooperation to explore outer space‚ even though considering the complexity‚ high cost and tremendous risk involved in outer space activities. The human world and outer space are now increasingly inseparable. The use of outer space has formulated a major part of our lives‚ such using outer space for telecommunications‚ navigation‚ meteorology and remote

vast expands of space. They foreshadow an understanding of space that humans seem very far from. But‚ how far are we truly from that point? The only way to find out would to be to continue the complicated research of space that has been going on since the space race. However space exploration is surrounded with controversy which may possibly affect the growth of the knowledge of space. The prior benefits and consequences of space exploration now affect the present and future of space exploration.

Contested Space Although many strive to avoid it‚ people are running into contested space moments after they open their eyes each morning. We form these walls of contested space automatically‚ sometimes subconsciously which comes into play as we go about life. Contested space is a generally used term; that has a fairly vague definition. However‚ Mary Louise Pratt In her work: Arts Of The Contact Zone expresses it use well‚ stating: “ I use this term to refer to social spaces where cultures meet

Deviance is not usually a crime‚ but may be seen as one. Deviance is when someone breaks the norms and values of a society‚ but the act is not illegal. Crime is where a person beaks the law of land‚ they either do something they shouldn’t‚ or they don’t do something they should. Crime and deviance can be measured with the use of Official Crime Statistic (OCS). OCS is the crimes which are reported by the victim‚ and then further recorded by the Police. Not all crimes are recorded by the Police‚ which

The Space Race In the beginning of the 1950’s tensions were high between the Soviets and the U.S. The Cold War had become known worldwide as a nuclear arms race between two super powers. However‚ a new kind of race had begun between the two countries‚ The Space Race. This was a race to control the outer space surrounding Earth‚ which could ultimately act as a nuclear missile path. Controlling outer space with nuclear capabilities could mean massive destruction for the world as we know it. The two

This year in science‚ we were paired up in groups to build a car powered only by a rubber band. There was a lot of physics and thought put behind the planning of our car. The rubber band moved the car by storing up elastic potential energy which then turned into kinetic energy when released. Newton’s Laws of Motion also come in handy when thinking about how to keep the car moving. “An object in motion stays in motion.” There was also a lot of thought put into the wheels. We had to be aware of the

to discoveries of new life‚ space exploration has led to much advancement‚ including ones that we use in our daily lives. An example would be those comfortable beds that are made of memory foam. Unlocking the mysteries of what’s beyond or planet is the solution to many problems we have here on earth. The possibility of finding new resources and life in space‚ overpopulation on planet earth and finding a new source of fuel are just a few of many reasons to encourage space exploration. Planet earth
