In the new episode "Apollo’s Daring Mission," astronauts and engineers provide inside information on the Apollo 8 space mission, the first manned mission to the moon. Originally intended to be only an earth-orbit mission, Apollo 8 was transformed into a desperate sprint for the lunar surface after the bitter setback that was Apollo 1, which culminated in a deadly fire. Against the very real threat that Russia would reach the moon first, the Apollo 8 team risked everything while relying on untried new technology.
