new perspective on our solar system‚ by being able to view how nature works outside of our own planet. Earth is a unique planet. So unique that our technology today has not discovered any other planets or satellites that could sustain human life. The earths atmosphere is composed of about 80 percent nitrogen and 20 percent oxygen however‚ space exploration might lead to a discovery of a similar planet to escape the depletion of our atmosphere. Technology in our current generation is ever changing
