Space is a big platform for new scientific discoveries and breakthroughs. The problem of exploring space and resources allocated to it is considered controversial. Some people believe that exploring space is vital as threats from space are realistic and have to me eliminated. Another group of people is convinced that there are more important problems and questions to be solved on Earth. Supporters of this opinion, ask reduction of space missions' frequency. Decreasing the frequency of space explorations is a good idea, as there are, unfortunately, multiple social and environmental threats.
