Should people spend money on space explorations?

       I think it's ok to spend money on space exploration (development). In a year, NASA spends about two trillion dollars , and even Japan, though having no money, spends about two hundred billion dollars on space exploration. I chose this topic because recently, I read a comic which mentioned this topic.
       Some people say that spending money on astrology and space technology would be a smarter and convenient way to learn more about space, since those groups would make major scientific leaps in a less amount of money than actually sending humans and machinery to space.
       So first of all, one advantage of actually sending an astronaut or machine to space is that they might find new minerals or precious material that an astronomer would not be able to collect by looking into his or her telescope. A famous example of this is that the asteroid probe Hayabusa succeeded in collecting samples of debris from the asteroid Itokawa. Not only did the achievement of Hayabusa create a path towards learning more about planets and how they formed, it also created an interest in space inside many minds. Because of this event, more people were encouraged to look up to the skies and ponder about what mysteries lay beyond it.
       Another advantage of spending money on space exploration, is that we can hope for a giant leap in the medicine field in space. Did you know that there is a module in the International Space Station where you can do experiments inside zero gravity? This is the only place where astronauts can actually study and experience medicine in space. There might be a big development in the medicine field in the future because of this module in ISS.
      Finally, the last reason of spending a lot of money on space development is because space exploration satisfies the human urge and need for exploration. Even though this might be a fuzzy reason to move such a large amount of money, I think this is the core to why so many people look up to and dream about space. Some people just love the thrill of adventure, making the impossible  possible. Only the people who have actually gone to space would know the excitement of going outside of the planet we humans live in.
      In conclusion, I think it is necessary to spend money on space exploration. By actually going to space, we might discover new things such as minerals and material, find new discoveries in the medicine field, and feel the thrill and excitement of going to outer space. I think we should continue to explore more about the planets and asteroids that surrounds our home planet earth.
