Wernher Von Braun was illustrated with a painting of a wheel-shaped space station, the skin cut away to reveal interior fittings like a submarine. About 1970, after years of trying to design round space stations, engineers concluded that the parts were too large to be launched from earth and that construction in space was difficult and dangerous. Modules for today's International Space Station are sent up one at a time and docked to the existing structure. The ISS looks like a disjointed insect, but it works. According to Armstrong, the Japanese have taken the lead in planning for space tourism.
