| Description |
Indicates that the problem of getting to Mars of Venus, heretofore a concern only to science fiction writers and afficionados, has now become an international obsession. Shows that the strides being made in the space race would not be possible were it not for the work of Copernicus and other scientists of his stature. States that it was Copernicus who realized that the earth is not the center of the universe but merely one of many heavenly bodies, all moving according to a definite system.
