This year World Space Week is celebrating discovery and imagination. The U.N. General Assembly declared Space Week a holiday in 1999 to celebrate Oct. 4 -- the date that Sputnik-1, the first artificial satellite, was launched in 1957 -- and Oct. 10, when the assembly adopted the Outer Space Treaty of 1967.
