Space exploration is much too expensive and the money should be spent on more important things Humanity has been exploring space for half of a century already. This is the most fascinating step of the progress and the most thrilling discovery of the twentieth century. Everyone at least once in life was interested in what surrounds our planet and who else lives in the world or we are just alone Space exploration brought a lot of innovations such as navigation systems, weather forecast, TV etc and today we can't imagine living without these discoveries. The biggest problem for humanity nowadays is pollution and global warming. They can bring drought and flood which means that our planet is becoming unfit for life. We will probably need the second home, a new place for living and space exploration can help to discover it. Humanity achieves big progress on space exploration, but any progress coasts a lot of money, especially for space. But space exploration is a very important science for humanity and we only begin this big journey. So I think that even it's much too expensive it is worth it.
