Why do countries spend money on space exploration?
Space exploration is an important strategic direction. It can respond to a very large number of areas. Now it is a communication, navigation, photographing the surface and much more. In the field of geology and chemistry we are interested in the resources of the planets around us. Very interesting and unexplored effects occur in black holes. And this is just the tip of the iceberg. Why is this money not being spent on health care? In our country, health care is given a lot of money. And if we do not support the space program, we can succumb to our enemies in arms, and they will take advantage. Many countries that do not have military capabilities are not spending money on space exploration, because they will never catch up with Russia and America in this area. The best solution would be for them to spend money on health care. Often the level of health care is high, then do not invest in a lot of money. It would be better to spend it on infrastructure improvements. But all this is not about our country! Russia is one of the most influential countries in the world and that our opinion was decisive, we must be strong. Only by investing in space exploration that we can maintain the defense of our army, because that space is a very promising area for the protection of the country.
