In this documentary, part of the 20th Century With Mike Wallace series from CBS News and the History Channel, series host and CBS News correspondent Mike Wallace takes a behind-the-scenes look at some recent problems with the National Aeronautics and Space Administration, commonly known as NASA. This episode first looks at the history of the glory days of NASA and how the space agency has been criticized from the time of the moon landing to the era of space shuttle launches. 20th Century With Mike Wallace features an exclusive interview with former NASA head Dan Goldin, who discusses some of the agency's problems in depth. There are also interviews with some past and present NASA personnel who speculate about why NASA has seen more than its fair share of crises recently, both high up in space and on the ground in Congress. ~ Cecilia Cygnar, Rovi
