Apollo 8

Apollo 8Moved ahead in the schedule due to ongoing difficulties with the construction of the lunar module, Apollo 8 lifts off from Cape Canaveral on a mission that represents NASA’s biggest gamble yet in the race for the moon: on only the second manned Apollo flight, astronauts Frank Borman, Jim Lovell and Bill Anders will go to the moon, orbit it in their command/service module, and return to Earth (the lunar module is still in the late stages of development). Mission planners plot out a free return trajectory – ensuring that without engines, Apollo 8 could loop around behind the moon and swing back toward home.

This mission is dramatized in the 1968 episode of HBO’s 1998 series From The Earth To The Moon.

Live From The Moon

Apollo 8Broadcasting live black & white television pictures from lunar orbit on Christmas Eve, the crew of Apollo 8 delivers one of the most-watched broadcasts of 1968. As the surface of the moon rolls silently outside the windows of their command/service module, the astronauts take turns reading the first chapter of Genesis, dedicating it to “all of you on the good Earth.” After ten orbits of the moon, Apollo 8 fires its engine, putting it on a return trajectory to Earth; it splashes down safely three days later.

This mission is dramatized in the 1968 episode of HBO’s 1998 series From The Earth To The Moon.
