Apollo 11

Two years after the discovery of "Sue," the largest and most complete Tyrannosaurus Rex skeleton found to date, government officials seize the remains and claim that "Sue" was stolen from federal land.

On December 7, 1972, NASA launched Apollo 17, a lunar mission crewed by Eugene Cernan, Ronald Evans and Harrison Schmitt. It would be the last time humans traveled beyond low Earth orbit, the last time man landed on another celestial body, and the last time man went to the moon. The Last Steps uses rare, heart-pounding footage and audio to retrace the record-setting mission.
