?Big Bertha? was one of the moon rocks brought back by the Apollo 14 crew for geological analysis. What it revealed stunned scientists.
After the near-disaster of Apollo 13, NASA faces increased political and public pressure to prove moon landings are still worth the cost and the risk. Despite a series of missions that push science and engineering to the limit, the program is ultimately grounded, not by dangers or disasters, but by budget cuts. Experience Apollo's last, glorious chapter, presented through interviews with the astronauts who took part in the final adventures and the stories behind objects inside Smithsonian's National Air and Space Museum.
