The prospect of doing business in space has been discussed for many years. Today, it is a commercial reality. The direct economic benefits already have been demonstrated in space transportation, satellite communications, and remote sensing markets. The indirect benefits have been equally significant. Space-related technologies applied to earth-based industries have resulted in new and innovative techniques and processes that improve the quality of production. Additional areas of economic potential will develop with the establishment of space-based facilities and further research into materials processing in space. Entirely new and unforseen space markets are likely to emerge as man's activity in space increases. This report identifies existing and potential worldwide markets for space-related goods and services, focusing on five major areas: (1) Space Transportation, (2) Satellite Communications, (3) Satellite Remote Sensing, (4) Space-Based Industrial Facilities, and (5) Materials Research and Processing in Space. The report also examines aspects of Insurance and Finance relevant to commercial ventures in these markets. Finally, the report presents assessments from U.S. industry representatives on their ability to compete against foreign competition in each of the five major areas.
