Space Station Designs Still Inspire 40 years Later
In the 1970's, toward the end of the Apollo program, U.S scientists and engineers debated the evolution of humans in space.
On to Mars? Or should we focus on building communities and industry in near earth orbits?
Advocates of near earth and lunar resource utilization met during NASA's 'Space Settlements - A Design Study' symposium in the summer of 1977 to present their views.
While their designs never came to fruition, they did help push U.S. policy toward LEO space stations (think Skylab) and the space shuttle -- and the rest is history.
It may all look a little quaint today -- but take a look at three of the most popular designs.
After 40-plus years, they still inspire.
