Space Week 2012
The the 13th annual week long international celebration of spaceflight and exploration ran from Oct. 4 through today. Both dates are key dates in the history of space exploration. On Oct. 4, 1957, the Soviet Union lofted Sputnik 1, humanity’s first-ever artificial satellite. And the Outer Space Treaty, which forms the basis for international space law, came into effect on Oct. 10, 1967.
