context: The crew of Apollo 8 sent the first live televised pictures of the Earth and the Moon back to Earth, and read from the creation story in the Book of Genesis, on Christmas Eve, 1968. An estimated one-quarter of the population of the world saw—either live or delayed—the Christmas Eve transmission during the ninth orbit of the Moon. The mission and Christmas provided an inspiring end to 1968, which had been a troubled year for the US, marked by Vietnam War protests, race riots, and the assassinations of civil rights leader Martin Luther King, Jr., and Senator Robert F. Kennedy.
