Space Exploration

Space exploration is the use of astronomy and space technology to research outer space. Physical exploration of space is conducted by human spaceflights and by robotic spacecraft. However, the technology that is used for exploring space wastes a lot of money that can be used for other things. - good opening

On the one hand, a lot of money and time that can be used for researches about things like health or technolodgy is spent on space exploration. In addition, it pollutes space. For an example, a few months ago two satellites clashed in space - that accident led to serious pollution in space. I think that this investment should be invested in Earth researches.

On the other hand, space exploration might help saving Earth from natural and unnatural threatening elements from space, (like asteroids or missiles that are launched out of the atmosphere and come back to hit the target. This way, space exploration saves our next generations.

To conclude, I think space exploration is unnecessary at this period. I think we should focus on problems on Earth and after that on less distressing problems.
