Nowadays people spend a lot of money on space exploration. Nowadays people spend a lot of money on space exploration. I think everyone has ever heard about Elon Musk. This American multimillionaire had invented «Tesla» car, a kind of electric car which was sent to the Earth’s orbit in February. But should we pay so much attention to space researches? In my opinion, space investigation is one of the most important things for people’s future. A tiny piece of the Universe is explored by humans and the rest of it can hide a lot of different mysteries. Maybe, forms of the sensible life will be finally found and we’ll have a contact with other civilizations. Without any doubt, there live too many people on the Earth nowadays. Human population is quickly increasing and there won’t be enough place for dozens of years. That’s why we should colonize Mars and any other planets in the nearest future. Despite of all discoveries connected with space, some people believe up to now that itsʹ investigation is a waste of time and money. They suppose that humanity should solve problems we have on the Earth instead of «useless» space researches. Sceptics also say that there is no sence in spending so much money on rocketsʹ building because they sometimes fall down and millions of dollars just «burn» down in the air. I think, people who keep to this opinion just not worry about the future. Such problem as lack of resources becomes more actual within years. Oil reserves are quickly disappearing and we havenʹt already invented a way to replace it. In conclusion Iʹd like to say that space exploration is really important for the humanity. It must be developed by all worldʹs scientists.
