NASA’s earliest astronauts are starring in a new space exhibit called “Heroes and Legends.” Thirty astronauts gathered at Kennedy Space Centre in Florida on Friday for the opening of the exhibit that features personal memorabilia and even rockets from NASA’s golden age of the 1960’s and ‘1970’s. Astronauts Jim Lovell and Buzz Aldrin had extra reason to celebrate as Friday marked the 50th anniversary of their launch of Gemini 12, the last flight of that program. Also present were the children of the late Alan Shepard, the first American in space and the late Neil Armstrong, the first man to walk on the moon. The event was deliberately held on Veterans Day in the United States.
