Today we have Lyndon B. Johnson's predictions for the future of space exploration, as printed in the book 2063 A.D..
Perhaps the outstanding feature of a prediction about the next century in space is that our imagination today is too limited to visualize the vast possibilities. In other words, more will be accomplished in space than we can now come anywhere near labeling as specific projects and benefits.
Among the space activities in the next one hundred years will probably be: weather control, global communication, global navigation, regular travel of people and freight between places on earth and space stations and the planets, and international policing against space and terrestrial conflicts.
The benefits flowing from space activities will be even more widespread than the space activities per se. Education, language, living standards, and world peace will all benefit as space exploration and space living become a permanent part of man's institutional structure.
