Nations allocate its money to support Space Exploration and show people up that the countries have the most modern technology. In addition, Space Exploration can also give more information for people about whatever is out of the Earth, so it will have completed available knowledge and can decrease their curiosity. Another one, the people can prevent some problems or threats in the future by understanding reports which they have from result of the program. For example, the experts can predict that a big meteor which can probably destroy the earth will come after learning its signs. Therefore, the countries all around the world can work together to find out a new planet to stay. 

On the other hand, some recent issues have not been completely finished such as climate change, poverty, homeless, and famine on which governments should focus more than the Space Expedition. They are able to use the resources to accelerate for declining the problems after formulating solutions. This prevention tends to lead to real impacts in short time. For instance, the local council can use national income to create new programs such as giving capital for poor families to open a business, establishing new work fields for employees, and building new apartments or flats for homeless. They will be able to increase public welfare and rescue more people life.
