America’s Secret Space Heroes Season 1

America's conquest of space may be our nation's finest moment. But behind the faces of fearless astronauts like John Glenn and Buzz Aldrin and a crusading president stood an army of unsung heroes and heroines: the engineers, mathematicians, designers and technicians who actually built the machines that put humanity in space. AMERICA'S SECRET SPACE HEROES unearths the untold stories of the space program - from the men and woman who created everything from the Saturn V moon rocket to the first successful Mars lander. AMERICA'S SECRET SPACE HEROES premieres on Smithsonian Channel on Sunday, May 14 at 9 p.m. ET/PT.
