I would like to tell you about space exploration. For a very long period of time people have been dreaming of visiting other planets and exploring the open space. The exploration of space began in the second half of the XX century.
Nowadays it is developing rapidly. But there is only one problem. Though billions of dollars are spent on the development of astronomy and astronautics, it may seem that these branches do not make any progress.
