On that Christmas eve of 1968

Apollo 8 first broadcast the full view of earth from the moon.

December 24, 1968 – Apollo Program: U.S. spacecraft Apollo 8 enters orbit around the Moon. Astronauts Frank Borman, Jim Lovell and William A. Anders become the first humans to see the far side of the Moon and planet Earth as a whole. The crew also reads from Genesis.

After launching on December 21, 1968, the crew took three days to travel to the Moon. They orbited ten times over the course of 20 hours, during which the crew made a Christmas Eve television broadcast in which they read the first 10 verses from the Book of Genesis. The crew timed this reading to coincide with a full view of planet Earth hanging in the empty blackness of space while clearly showing the rich diversity of the living planet as indicated in Earth's colors, seas, landforms, and weather patterns, rising over the dull gray horizon of the lifeless Moon. At the time, the broadcast was the most watched TV program ever. Apollo 8's successful mission paved the way for Apollo 11 to fulfill U.S. President John F. Kennedy's goal of landing a man on the Moon before the end of the decade.

1968 NASA launched Apollo 7

Apollo 7 (October 11-22, 1968) was the first manned mission in the Apollo program to be launched. It was an eleven-day Earth-orbital mission, the first manned launch of the Saturn IB launch vehicle, and the first three-person American space mission. The crew consisted of Mission Commander Walter M. Schirra, Command Module Pilot Donn F. Eisele, and Lunar Module Pilot R. Walter Cunningham. The mission was intended as a test flight of the newly redesigned module. Accordingly, it flew low around the Earth so its crew could track life-support systems, the propulsion systems and the control systems. Despite emotional tension amongst the crew the mission was a technical success, which led NASA to launch Apollo 8 just two months later.
