Apollo 8: A Historic Journey to the Moon and Back in 1968
The Apollo 8 astronauts’ demonstration of navigation beyond Earth orbit and the Apollo Command’s space worthiness at lunar distances in 1968 marked a major step forward for NASA toward the Moon landing. The Lunar Module was to be tested on two more flights, Apollo 9 and Apollo 10, while in Earth orbit.
Apollo 8 Preflight Moments: A Window Into History at the Kennedy Space Center and White House
.
NASA’s preflight crew news conference for astronauts James A. Lovell, Frank Borman, and William A. Anders took place on December 2, 1968, at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. The crew’s preparedness was noted during the conference. On December 9, 1968, President Lyndon B. Johnson welcomed the astronauts from Apollo 7 to a state dinner at the White House, and invited the astronauts from Apollo 8, who were just 12 days away from their historic launch to the Moon. Borman, Lovell, and Anders, along with their backups, Neil A. Armstrong, Edwin E. “Buzz” Aldrin, and Fred W. Haise, participated in the countdown demonstration test at NASA’s Kennedy Space Center (KSC) in Florida. The event marked the beginning of NASA’s journey to the Moon and the historic launch of the first spacecraft to orbit the Earth.
Apollo 8 Countdown Demonstration Test: Engineering Precision and Crew Capability
At Launch Pad 39A, the Apollo 8 launch vehicle was utilized for a countdown demonstration test. Before their lunar launch at NASA’s Kennedy Space Center in Florida, the crew—Frank Borman, James A. Lovell, and William A. Anders—celebrated.
Between December 5 and 11, engineers at KSC’s Launch Complex 39 finished the “wet” and “dry” phases of the Apollo 8 Countdown Demonstration Test (CDDT). The complete countdown, including the fuel loading and first stage engine ignition times for all five F-1 engines, was replicated in the first wet phase. For safety reasons, the crew decided not to take part. Workers recycled the countdown and took the rocket’s fuel out before December 31. The countdown proceeded until the first stage ignition as the astronauts were ready and strapped up inside the capsule. The Mission Control Center at MSC and the Manned Space Flight Network were connected to the CDDT.
Apollo 8’s Magnificent Launch and Trans-Lunar Injection: An Amazing Moon Journey
The spent S-IVB third stage shows the launch of Apollo 8, Earth’s swift return following Trans-Lunar Injection, and the Lunar Module Test Article-B (LTA-B).
The first stage of the Saturn V launched five engines on December 21, 1968, with a maximum thrust of 7.5 million pounds. Three flight director teams, commanded by Lead Flight Director Clifford E. Charlesworth and Flight Directors Glynn S. Lunney and Milton L. Windler, supervised the mission. As the capsule communicator, Michael Collins, the astronaut in MCC, had direct communication with the crew. In 11.5 minutes, the three Saturn V stages sent Apollo 8 into Earth orbit. Capcom Collins instructed the crew to use Trans-Lunar Injection (TLI), a less theatrical way of declaring one’s departure for the moon, after reviewing the spacecraft’s systems. The goal was to find a way to the Moon while avoiding Earth’s gravitational pull. The third stage of Apollo 8
Mapping the Unknown: Apollo 8’s Journey via Van Allen Belts, Lunar Orbit, and the Historic Descriptions of the Unseen Moon
Through the Van Allen radiation belts on Earth, Borman, Lovell, and Anders, among others, reached the Moon’s gravitational field. Apollo 8 reached the leading edge of the Moon and vanished behind it, losing communication with Earth 69 hours after takeoff. For a few anxious minutes, the astronauts performed the Lunar Orbit Insertion maneuver while behind the moon. MCC confirmed that the Moon landing was successful, and as no one had ever seen it before, the astronauts started to describe it.
Apollo 8’s Lunar Odyssey and Historic Splashdown: A Moon-to-Earth Journey
Humans first saw the Tsiolkovski Crater on the Moon’s far side during Apollo 8. After splashdown, the astronauts were waiting in the life raft to be picked up by a rescue helicopter.
After completing 10 lunar circles in twenty hours, astronauts Borman, Lovell, and Anders wished everyone on Earth a Merry Christmas. They completed their final revolution, disappeared behind the Moon, and fired up the engine to launch their ship out of lunar orbit and back to Earth. As soon as Lovell said, “There is a Santa Claus,” the engine had burned as intended. Following an extraordinary six-day expedition, they spent three days coasting toward Earth before making a splashdown in the Pacific Ocean just before daybreak. Rescue crews from the flagship U.S.S. Yorktown (CV-10) hauled them out of the water and onto the carrier.
Honoring Comeback and Heritage: Hickam and Ellington AFBs Welcome Apollo 8 Astronauts, and the Chicago Museum of Science and Industry’s CM Exhibit
Apollo 8 astronauts William A. Anders, James A. Lovell, and Frank Borman were listening to Hawaii Governor John A. Burns while serving as temporary residents of Hickam Air Force Base in Honolulu. Before heading back to the Chicago Museum of Science and Industry, they gave a few quick words to a gathering of folks at Ellington AFB in Houston.
Along with others, Borman, Lovell, and Anders departed Yorktown on the Apollo 8 mission, which was destined for Hickam Air Force Base in Honolulu. On December 29, Hawaii’s Governor John A. Burns welcomed them back to Houston. To protect Yorktown’s systems, the CM was taken out and shipped to the North American Rockwell Space Division in Downey, California, for a postflight analysis. Since 1971, the Chicago Museum of Science and Industry has exhibited the Apollo 8 CM. TIME magazine named Borman, Lovell, and Anders their 1968 Men of the Year. An important step toward the Moon landing was taken with Apollo 8.
Apollo 8 Countdown Test: Unveiling Lunar Module Plans and the Journey to Apollo 9
At NASA’s Kennedy Space Center in Florida’s Launch Pad 39A, astronauts James A. McDivitt (left), David R. Scott, and Russell L. Schweickart (right) pose in front of the Apollo 8 Saturn V during its final countdown demonstration test.
The LM was one of the parts of the lunar mission design that Apollo 8 did not test because of development delays. Apollo 9 was tasked with performing the first crewed assessment of the LM, and it was planned for late February 1969. NASA designated James A. McDivitt, Russell L. Schweickart, and David R. Scott as the primary crew for the ten-day Earth orbital mission; Charles “Pete” Conrad, Richard F. Gordon, and Alan L. Bean served as backups. Scott stayed in the CM, while Schweickart and McDivitt were going to go into the LM. Schweickart intended to perform an approximately two-hour spacewalk before the two spacecraft undocked. He would use handholds that had been prepositioned to translate from the LM to the CM, where Scott was waiting for him in the open hatch. The purpose of the twin spacewalk was to show off a backup transfer option in case the internal transfer tube encountered issues. Before the Moon landing, the spacewalk would be the sole opportunity to test the new Apollo A7L spacesuit in space. After the spacewalk, Schweickart and McDivitt were going to undock the LM, test the engines of the descent and ascent stages, and fly the spacecraft independently for up to 100 miles before getting back in the CM to meet Scott.
Testing the Future: Houston’s Space Environment Simulation Laboratory hosts the Apollo 9 Crew’s Test of the Novel Apollo A7L Spacesuit
The new Apollo A7L spacesuit is tested by Apollo 9 prime and backup crew in the Manned Spacecraft Center’s Space Environment Simulation Laboratory (now NASA’s Johnson Space Center) in Houston. Alan L. Bean, Russell L. Schweickart, and David R. Scott, on the left.
Two versions of the Apollo A7L space suit were created by the Dover, Delaware-based International Latex Corporation (ILC) for NASA: one was designed for use only inside the spacecraft, for example during launch, and the other was made so that astronauts could also use it during spacewalks by using the Portable Life Support System (PLSS) backpack. Although the inner version of the suit could function in a vacuum, crew members wearing it were still connected to the spaceship by hoses that carried oxygen and other life support supplies.When doing spacewalks outside the spacecraft, such on the lunar surface, the PLSS of the external variant supplied the necessary oxygen and communications. Although McDivitt had no intention of performing a spacewalk, he and Schweickart wore the exterior versions of the suits on Apollo 9, whereas Scott wore the inside version. The A7L spacesuits of McDivitt, Scott, Schweickart, and Bean were tested in vacuum using the PLSS in Chamber A of the MSC Space Environment Simulation Laboratory.
Apollo 9: The Intricate Assembly Process at NASA’s Kennedy Space Center
The Apollo 9 spacecraft is built at NASA’s Vehicle Assembly Building at the Kennedy Space Center in Florida prior to the Apollo 10 first stage joining it. The landing gear of the Lunar Module is being raised by workers in order to put it atop the Saturn V rocket. Employees of NASA are doing the procedure.
At KSC’s Manned Spacecraft Operations Building (MSOB), the Apollo 9 LM was mounted in the Spacecraft LM Adapter (SLA) on November 30. After that, the spacecraft was put together and transported to the Vehicle Assembly Building (VAB) so that it could be placed on the High Bay 3 Saturn V rocket.
Apollo 10: Preparation for Lunar Exploration – Stacking Stages at Kennedy Space Center
At the Kennedy Space Center in Florida, NASA employees touch down the third stage of the Apollo 10, stack the second stage of the Apollo 10 S-II, and prepare the first stage of the Apollo 10 S-IC for stacking on the Mobile Launcher.
Apollo 10, a mission scheduled for May 1969 to test the lunar orbit of the spacecraft, was still under preparation. Thomas P. Stafford, John W. Young, and Eugene A. Cernan made comprised the first all-veteran crew; L. Gordon Cooper, Donn F. Eisele, and Edgar D. Mitchell served as backups. They intended to undock their Lunar Module (LM) and fly it to a distance of nine miles before coming back to the lunar surface. By December 7, 1969, Kennedy Space Center (KSC) technicians had stacked the first two stages of the Apollo 10 Saturn V rocket in the VAB’s High Bay 2.
Testing and Preparation at NASA’s Kennedy Space Center: Apollo 9 and Apollo 10 Spacecraft Assessments
Apollo 9 spacecraft testing takes place at the Manned Spacecraft Operations Building at NASA’s Kennedy Space Center in Florida. Engineers tested the Apollo 10 CSM and LM docking in the nearby MSOB on December 11. Before the lunar module was put through its paces for altitude testing in January 1969, technicians mated the ascent and descent stages in a vacuum room. Together with the prime and backup crews, engineers checked the height of the Command Module.
Significant Moments in Training: Chief Test Pilot’s Narrow Escape from Lunar Landing Training Vehicle-1 (LLTV-1)
Chief Test Pilot Joseph S. “Joe” Algranti uses his parachute to safely float to the ground after jumping from the Lunar Landing Training Vehicle-1, which explodes as it strikes the earth.
The Lunar Landing Training Vehicle (LLTV) was used by the Apollo commanders to practice flying the Lunar Module (LM), particularly the last 200 feet of the descent. NASA grounded the fleet after Armstrong’s tragedy in an earlier model of the training aircraft on May 6, 1968. Chief test pilot Joseph S. “Joe” Algranti of MSC began flying LLTV-1s again in October 1968, and colleague pilot H.E. “Bud” Ream flew 14 test flights to evaluate the vehicle. Algranti launched LLTV-1 on the fifteenth mission, ascending to a height of 680 feet, and executed a lunar landing simulation. However, unforeseen gusts of wind overpowered the craft’s aerodynamic control, causing it to abruptly stop. Algranti parachuted out and landed safely, suffering only minor injuries; LLTV-1 crashed and caught fire.
The Path of LLTV-3: From NASA’s Langley Research Center for Critical Wind Tunnel Testing to Ellington Air Force Base
To load the LLTV-3 into the Super Guppy cargo plane for wind tunnel testing at NASA’s Langley Research Center in Hampton, Virginia, workers at Ellington Air Force Base are getting ready.
The LLTVs were shut down by NASA, and Walter M. Schirra chaired the commission of investigation. NASA dispatched LLTV-3 to Langley Research Center for wind tunnel testing. The LLTV-1 accident was brought on by a wind gust that went above control limits and had nothing to do with Armstrong’s tragic death. One proposal was to boost the thrust level of the craft’s thrusters by fifty percent in order to enhance safety.
