ATK/NASA Space Shuttle Return To Flight Commemorative Pin
The loss of the space shuttle Columbia was one of the darkest hours in NASA's more than 50-year history. It took two years before American astronauts would return to space. The voyage, an important milestone for the space program, can be celebrated with the ATK/NASA Space Shuttle Return To Flight Commemorative Pin. The limited-edition pin, stamped with the authentic NASA "Return to Flight" program emblem and the official mission slogan "Smarter, Stronger, Safer," is available only to SPACE.com fans.
