Americana: 3 Jul 11: America's adventures in Space

As the final Shuttle mission nears, Jonny Dymond looks at America's
adventures in Space. Curators at the National Air and Space Museum
are on hand to talk about America's past - and what might yet lie
ahead. George Takei of "Star Trek" recalls that when his show began
broadcasting on TV, space travel was science fiction. But its
characters, Mr. Sulu, Captain Kirk and Spock among others, helped
guide the nation in its real aspirations into the unknown.
Astronaut and flight engineer Suni Williams revisits her
experiences on the International Space Station. And Americans in
Roswell, New Mexico celebrate the annual UFO festival.
