Q. Should countries invest so much to explore space. I think countries should not invest to explore space. Firstly, each we don't have to move to space right now. So when the time comes, it's not too late if countries start then. There's no need to try similar space missions on and on again to waste money. Secondly, each space mission costs billions of dollars. This money can be used to save poor people around the world, or improve the Earth. It would be a great loss if the mission fails. In conclusion, it's not worth the money to invest in space missions.
