Apollo 8.
~7 min read · Ch. 1 of 8
On the 4th of October 1957, the Soviet Union launched Sputnik 1. This small metal sphere changed everything for the United States. It proved Moscow could deliver nuclear weapons across continents. American leaders felt their global standing was under direct threat. President John F. Kennedy believed national interest required space superiority. He needed a goal beyond existing rocketry capabilities. The Soviets had heavier lifting rockets than America possessed. Kennedy chose to land a man on the Moon and return him safely. Project Apollo became the vehicle for this competition. The race was not about science or economics alone. It was about proving American power against a rival ideology. The launch of Sputnik triggered what historians call the Space Race. Fear drove the urgency behind every decision made in Washington.
Mission Profile Redesign
NASA originally planned Apollo 8 as a test flight for early 1969. The mission would orbit Earth in an elliptical path. Engineers intended to test both command and lunar modules together. Lunar Module-3 arrived at Kennedy Space Center in June 1968 with over one hundred defects. Bob Gilruth concluded LM-3 would not be ready until February or March 1969. George Low proposed sending just the command module to the Moon instead. This change allowed testing lunar landing procedures earlier than scheduled. The new plan moved the mission from December 1968 to the 21st of December 1968. Jim McDivitt's crew trained for the original lunar module test. They were reassigned to fly Apollo 9 instead. Frank Borman's team received only two to three months less preparation time. They swapped their lunar module training for translunar navigation drills. The Saturn V rocket AS-503 had to be ready by December 1. Wernher von Braun confirmed pogo oscillation problems from Apollo 6 were fixed. James Webb authorized the risky CSM-only lunar orbit mission on the 9th of August 1968.
Apollo 8 launched at 12:51:00 UTC on the 21st of December 1968. The Saturn V rocket used its three stages to achieve Earth orbit before performing a trans-lunar injection burn.
Who were the crew members of Apollo 8 and how did they change?
Frank Borman served as Commander while William Anders took the Lunar Module Pilot role. Michael Collins suffered a cervical disc herniation in July 1968 and was replaced by Jim Lovell who had previously flown on Gemini VII and Gemini XII missions.
When did Apollo 8 splashdown occur after returning from the Moon?
Splashdown occurred at 15:51:42 UTC on the 27th of December 1968 in the North Pacific Ocean southwest of Hawaii. The command module landed upside down before an inflatable bag righted it into normal apex-up orientation forty-five minutes later.
Why was the mission plan for Apollo 8 changed from testing lunar modules to orbiting the Moon?
Engineers concluded that Lunar Module-3 would not be ready until February or March 1969 due to over one hundred defects found upon arrival. George Low proposed sending just the command module to the Moon instead which allowed testing lunar landing procedures earlier than scheduled.
What famous photograph did William Anders take during the fourth pass across the front of the Moon?
William Anders saw Earth emerging from behind the lunar horizon and called out excitedly before taking a black-and-white photograph followed by color film shots. Life magazine selected this famous color photo as one of its hundred photos of the century and credited it as inspiration for the first Earth Day held in 1970.
Frank Borman served as Commander while William Anders took the Lunar Module Pilot role. Michael Collins was originally assigned as Command Module Pilot but suffered a cervical disc herniation. He underwent surgery and was replaced by Jim Lovell in July 1968. Lovell had flown twice before on Gemini VII and Gemini XII missions. This made him the first commander of a previous mission to fly as a non-commander. Lovell and Borman reunited as crewmates from their shared Gemini VII flight. Neil Armstrong led the backup crew alongside Buzz Aldrin and Fred Haise. Support crews included Ken Mattingly, Vance Brand, and Gerald Carr. These support personnel developed emergency procedures in simulators. The capsule communicator role rotated among astronauts like Michael Collins and Gerald Carr. Flight directors Clifford E. Charlesworth, Glynn Lunney, and Milton Windler managed three shifts. Each shift ensured prime and backup crews stayed informed about changes. The crew lived in quarters at Kennedy Space Center during final preparations. They received a visit from Charles Lindbergh and his wife Anne Morrow Lindbergh. Lindbergh explained how he measured fuel needs for his 1927 flight using string on a globe. The total fuel he carried was one-tenth what Saturn V burned every second.
Launch And Trans-Lunar Injection
Apollo 8 launched at 12:51:00 UTC on the 21st of December 1968. The Saturn V rocket used its three stages to achieve Earth orbit. The S-IC first stage landed in the Atlantic Ocean while the S-II second stage landed elsewhere. The S-IVB third stage injected the craft into Earth orbit. It remained attached to perform the trans-lunar injection burn. Mission Control gave permission for Apollo 8 to go to the Moon after checking systems. Collins radioed Go for TLI at 2 hours, 27 minutes, and 22 seconds after launch. The S-IVB engine ignited perfectly and performed the burn as planned. Speed increased from orbital velocity to injection velocity over five minutes. This set a record for highest speed relative to Earth that humans had ever traveled. The command and service modules separated from the spent third stage. Borman worried the S-IVB stayed too close to their spacecraft. They performed an additional separation maneuver to increase distance by 3 meters per second. Five hours after launch, Mission Control vented remaining fuel from the S-IVB. That stage entered solar orbit with an inclination of 23.47 degrees. The crew passed through Van Allen radiation belts within hours of launch. Each astronaut wore a Personal Radiation Dosimeter recording exposure levels. By mission end, they experienced an average dose of 1.6 milligray.
Lunar Orbit And Reconnaissance
During the fourth pass across the front of the Moon, the crew witnessed Earthrise firsthand. NASA's Lunar Orbiter 1 had taken the first picture of such an event on the 23rd of August 1966. Anders saw Earth emerging from behind the lunar horizon and called out excitedly. He took a black-and-white photograph before requesting color film for another shot. Life magazine later selected this famous color photo as one of its hundred photos of the century. The synchronous rotation of the Moon means Earth stays fixed in position relative to any single spot on its surface. Earthrise is generally only visible while orbiting or near the limb where libration carries it slightly above horizon. Anders continued taking photographs while Lovell controlled the spacecraft so Borman could rest. Everyone became extremely tired after three days without good sleep. Borman ordered Anders and Lovell to get some sleep despite protests. For the next two orbits, Anders and Lovell slept while Borman sat at the helm. As they rounded the Moon for the ninth time, astronauts began the second television transmission. Each man gave impressions of the lunar surface and what it felt like to be there. Borman described it as vast, lonely, forbidding expanse of nothing. Then Anders
Earthrise And Christmas Broadcast
announced they had a message for all those on Earth. Each man read sections from the Book of Genesis during the broadcast. Borman finished by wishing everyone a Merry Christmas and God bless all of you.
The trans-Earth injection occurred exactly on time scheduled for 89 hours, 28 minutes, and 39 seconds after launch. Voice contact was regained as the spacecraft re-emerged from behind the Moon. Lovell announced Please be informed there is a Santa Claus to which Ken Mattingly replied affirmatively. The spacecraft began its journey back to Earth on December 25, Christmas Day. On Christmas afternoon, crew made their fifth television broadcast showing how an astronaut lived in space. They found a small present from Slayton containing real turkey dinner with stuffing. Another surprise gift included three miniature bottles of brandy ordered left unopened until landing. At about 124 hours into mission, sixth final TV transmission showed best video images of Earth. Six minutes before hitting atmosphere, crew saw Moon rising above Earth's horizon as calculated. As module hit thin outer atmosphere, glowing plasma formed around spacecraft. Deceleration peaked at 6.6 g while computer controlled descent changing attitude. Drogue parachute deployed at altitude followed by three main parachutes. Splashdown position officially reported in North Pacific Ocean southwest of Hawaii at 15:51:42 UTC on the 27th of December 1968. Parachutes dragged craft over leaving it upside down in Stable-2 position. About six minutes later inflatable bag uprighted system righted command module

into normal apex-up orientation. First frogman arrived 43 minutes after splashdown. Crew was safe on flight deck of Yorktown forty-five minutes later.
Time magazine chose the crew of Apollo 8 as its Men of the Year for 1968. This recognition came despite political assassinations and unrest throughout that year. A stranger sent Borman a telegram stating Thank you Apollo 8 You saved 1968. One of most famous aspects was Earthrise picture taken during fourth orbit. It has been credited as inspiration for first Earth Day held in 1970. Life magazine selected it as first of hundred Photographs That Changed The World. There were 1,200 journalists covering mission making it widely covered since Mercury-Atlas 6. BBC broadcast coverage in 54 countries using fifteen different languages. Soviet newspaper Pravda featured quote describing flight as outstanding achievement of American sciences. Estimated quarter of people alive at time saw Christmas Eve transmission live or delayed. Apollo 8 broadcasts won Emmy Award highest honor given by Academy Television Arts Sciences. Madalyn Murray O'Hair brought lawsuit against NASA over Genesis reading though case rejected by Supreme Court. In 1969 United States Post Office Department issued postage stamp Scott catalogue number 1371 featuring detail from Earthrise photo. Words In beginning God appeared on stamp marking first words book Genesis. Just eighteen days after return crew appeared Super Bowl III pre-game show reciting Pledge Allegiance before
