55 Years Ago: Eight Months Before the Moon Landing

55 Years Ago: Eight Months Before the Moon Landing

November 1968 proved pivotal to achieving the goal of landing a man on the Moon before the end of the decade. The highly successful Apollo 7 mission that returned American astronauts to space provided the confidence for NASA to decide to send the next flight, Apollo 8, on a trip to orbit the Moon in December. At NASA’s Kennedy Space Center (KSC) in Florida, the Saturn V rocket and the Apollo spacecraft for that mission sat on Launch Pad 39A undergoing tests for its upcoming launch. In the nearby Vehicle Assembly Building (VAB), the three stages of the Saturn V for the Apollo 9 mission sat stacked awaiting the addition of its spacecraft undergoing final testing. Also in the VAB, workers had begun stacking the Apollo 10 Saturn V, while the Apollo 10 spacecraft arrived for testing. As the Apollo 8 and 9 crews continued their training, NASA named the crew for Apollo 10 and announced the science experiments that the first Moon landing astronauts would deploy.

Following their highly successful flight, Apollo 7 astronauts Walter M. Schirra, Donn F. Eisele, and R. Walter Cunningham returned to Houston’s Ellington Air Force Base on Oct. 26. On Nov. 2, President Lyndon B. Johnson presented the astronauts with Exceptional Service Medals at the LBJ Ranch in Johnson City, Texas. Four days later, comedian Bob Hope filmed an episode of his weekly television variety show in the auditorium of the Manned Spacecraft Center (MSC), now the Johnson Space Center in Houston. Hope saluted the Apollo 7 astronauts in a skit that included actress Barbara Eden, star of the television series “I Dream of Jeannie” that featured fictional astronauts. Paul P. Haney, MSC Director of Public Affairs and the “Voice of Mission Control,” also participated in the skit. Following the recovery of Apollo 7, the prime recovery ship U.S.S. Essex sailed for Norfolk Naval Air Station in Virginia, where on Oct. 27 workers offloaded the Command Module (CM), and placed it aboard a cargo plane to fly it to California for return to its manufacturer, North American Rockwell Space Division in Downey, for postflight inspection. On Jan. 20, 1969, the Apollo 7 astronauts as well as their spacecraft took part in President Richard M. Nixon’s first inauguration parade. In 1970, NASA transferred the Apollo 7 spacecraft to the Smithsonian Institution that loaned it to the National Museum of Science and Technology in Ottawa, Canada, for display. Following its return to the United States in 2004, it went on display at the Frontiers of Flight Museum at Love Field in Dallas.

On Nov. 12, 1968, NASA Headquarters put out the following statement: “The National Aeronautics and Space Administration today announced that the Apollo 8 mission would be prepared for an orbital flight around the Moon.” That momentous statement ended weeks of intense internal agency deliberations and public speculation about Apollo 8’s targeted mission. The original mission plan called for Apollo 8 to conduct the first test of the Lunar Module (LM) in Earth orbit, but when the LM fell behind schedule, NASA managers in August began contemplating sending the Apollo 8 crew on a lunar orbital test of the Command Module (CM). The decision hinged partly on a successful Apollo 7 mission, and with that milestone passed, NASA Administrator James E. Webb approved the daring plan. On only the second crewed Apollo mission, the first crew to launch on the Saturn V, and only the third launch of the mighty Moon rocket, with the second of those experiencing some serious anomalies, the decision weighed the risks against the benefits of achieving the Moon landing goal before the end of the decade. With the Dec. 21 launch date fast approaching, the Apollo 8 crew of Frank Borman, James A. Lovell, and William A. Anders and their backups Neil A. Armstrong, Edwin E. “Buzz” Aldrin, and Fred W. Haise had begun training for the lunar mission even before the official announcement. During a Nov. 16 press conference, Borman, Lovell, and Anders discussed their preparations for the historic mission. On Nov. 19, at KSC’s Launch Complex 39, engineers completed the Flight Readiness Test to validate the launch vehicle, spacecraft, and ground systems.

The LM formed a critical component to the Moon landing effort. Delays in preparing LM-3 for flight resulted in the crewed test to slip to Apollo 9 in early 1969. The three stages of the Apollo 9 Saturn V stood stacked on Mobile Launcher 2 in High Bay 3 of the VAB. The Apollo 9 spacecraft components, CSM-104 and LM-3, continued testing in the KSC’s Manned Spacecraft Operations Building (MSOB). The prime crew of James A. McDivitt, David R. Scott, and Russell L. Schweickart, as well as their backups Charles “Pete” Conrad, Richard F. Gordon, and Alan L. Bean completed several altitude chamber tests with CSM-104 during the month of November. On Nov. 30, workers placed LM-3 inside its Spacecraft LM Adapter, topping it with CSM-104 to complete the spacecraft for its Dec. 3 rollover to the VAB for mating with the Saturn V. McDivitt, Scott, and Schweickart conducted water egress training in the Gulf of Mexico near Galveston, Texas. On Nov. 25, workers aboard the Motor Vessel M/V Retriever lowered a mockup CM with the crew inside into the water in a nose-down position. Flotation bags inflated to right the spacecraft to a nose-up position. The astronauts then exited the capsule onto life rafts and recovery personnel hoisted them aboard a helicopter. Backups Conrad, Gordon, and Bean completed the test on Dec. 6.

On Nov. 13, NASA announced the crew for the Apollo 10 mission planned for the spring of 1969. The fourth crewed Apollo mission would involve the launch of a CM and LM on a Saturn V rocket. Depending on the success of earlier missions, Apollo 10 planned to test the CM and LM either in Earth orbit or in lunar orbit, the latter a dress rehearsal for the actual Moon landing likely to follow on Apollo 11. NASA designated Thomas P. Stafford, John W. Young, and Eugene A. Cernan as the prime crew, the first all-veteran three person crew. The trio had served as the backup crew on Apollo 7 and had flight experience in the Gemini program. As backups, NASA assigned L. Gordon Cooper, Donn F. Eisele, and Edgar D. Mitchell. Cooper had flown previously on Mercury 9 and Gemini VIII, Eisele had just returned from Apollo 7, while this marked the first crew assignment for Mitchell. As support crew members, NASA named Joe H. Engle, James B. Irwin, and Charles M. Duke.

Flight hardware in support of Apollo 10 continued to arrive at KSC. Following delivery of LM-4 in October, on Nov. 2 workers mated its two stages and placed the vehicle in one of the MSOB’s altitude chambers. Stafford and Cernan carried out a sea level run on Nov. 22. The CM-106 and SM-106 for Apollo 10 arrived at KSC on Nov. 23 and workers trucked them to the MSOB where they mated the two modules three days later. In the VAB, the Saturn V’s S-IC first stage arrived on Nov. 27 and workers erected it on Mobile Launcher 3 in High Bay 2, awaiting the arrival of the upper stages.

On Nov. 19, NASA announced that when Apollo astronauts first land on the Moon, possibly as early as during the Apollo 11 mission in the summer of 1969, they would deploy three scientific experiments – a passive seismometer experiment package (PSEP), a laser ranging retro-reflector (LRRR), and a solar wind composition (SWC) experiment – during their 2.5-hour excursion on the lunar surface. The PSEP will provide information about the Moon’s interior by recording any seismic activity. The passive LRRR consists of an array of precision optical reflectors that serve as a target for Earth-based lasers for highly precise measurements of the Earth-Moon distance. The SWC consists of a sheet of aluminum foil that the astronauts deploy at the beginning of their spacewalk and retrieve at the end for postflight analysis. During the exposure, the foil traps particles of the solar wind, especially noble gases.

On Nov. 14, engineers in MSC’s Space Environment Simulation Laboratory (SESL) completed a series of altitude tests with LM Test Article-8 (LTA-8) to certify the vehicle for lunar missions. Astronaut Irwin and Grumman Aircraft Corporation consulting pilot Gerald P. Gibbons completed the final test, the last in a series of five that started on Oct. 14. Grumman pilot Glennon M. Kingsley paired up with Gibbons for three of the tests. During the tests that simulated various portions of the LM’s flight profile, the chamber maintained a vacuum simulating an altitude of about 150 miles and temperatures as low as -300o F. Strip heaters attached to the LTA’s surface provided the simulated solar heat. NASA transferred the LTA-8 to the Smithsonian Institution in 1978 and it is now on public display at Space Center Houston.

In another reminder that the race to the Moon still existed, on Nov. 10 the Soviet Union launched the Zond 6 spacecraft. Although it launched uncrewed, the Zond spacecraft, essentially a Soyuz without the forward orbital compartment and modified for flights to lunar distances, could carry a crew of two cosmonauts. A cadre of cosmonauts trained for such missions. Similar to the Zond 5 mission in September, Zond 6 entered a trajectory that looped it around the Moon on Nov. 13, passing within 1,500 miles of the lunar surface. The spacecraft took photographs of the Moon’s near and far sides and of the distant Earth. As it neared Earth during its return journey, trouble developed aboard the spacecraft as a faulty hatch seal caused a slow leak and it began to lose atmospheric pressure. Ground controllers initially steadied the pressure loss and performed a final midcourse maneuver that allowed Zond 6 to perform a skip reentry to land in Soviet territory on Nov. 17. However, the spacecraft continued to lose pressure and a buildup of static electricity created a coronal discharge that triggered the spacecraft’s soft landing rockets to fire and cut the parachute lines while it was still descending through 5,300 meters altitude. Although the capsule hit the ground at a high velocity, rescue forces were able to recover the film containers. The Soviets at the time did not reveal either the depressurization or the crash but claimed the flight was a successful circumlunar mission. With two apparently successful uncrewed circumlunar flights and the resumption of crewed missions with Soyuz 3 in October, these Soviet activities perhaps played a part in the decision to send Apollo 8 to the Moon.

50 Years Ago: Launch of Skylab 4, The Final Mission to Skylab

50 Years Ago: Launch of Skylab 4, The Final Mission to Skylab

The third and final crewed mission to the Skylab space station, Skylab 4, got underway on Nov. 16, 1973, with a thunderous launch from NASA’s Kennedy Space Center (KSC) in Florida. Docking eight hours later, astronauts Gerald P. Carr, Edward G. Gibson, and William R. Pogue began a planned 56-day mission that program managers extended to a record-breaking 84 days. During their first month, as they adjusted to weightlessness and their new surroundings, they completed the first of four spacewalks. They began an extensive science program, investigating the effects of long-duration spaceflight on human physiology, examining the Sun, conducting observations of the Earth, as well as technology and student-led experiments. They began their systematic observations of recently discovered Comet Kohoutek as it approached the Sun.

In January 1972, NASA announced the astronauts it had selected for the Skylab program. For Skylab 4, the third crewed mission and at the time planned to last 56 days, NASA named Carr as commander, Gibson as science pilot, and Pogue as pilot to serve as the prime crew, the first all-rookie prime crew since Gemini VIII in 1966. For the backup crew, NASA designated Vance D. Brand, William B. Lenoir, and Don L. Lind, who also served as the backup crew for Skylab 3. Brand and Lind would serve as the two-person crew for a possible rescue mission.

Right: Workers in the VAB stack the second stage onto the first stage for the Skylab 4 Saturn IB.

Preparations at KSC for the Skylab 4 mission began on Nov. 4, 1971, with the arrival of the S-IVB second stage of the SA-208 Saturn IB rocket. Workers placed it in long-term storage in the Vehicle Assembly Building (VAB). The rocket’s S-IB first stage arrived on June 20, 1973. Workers in the VAB mounted it on Mobile Launcher 1 on July 31, adding the second stage later that same day.

Right: Workers at Launch Pad 39B replace the eight stabilization fins on the Saturn IB rocket’s first stage.

Meanwhile, Command and Service Module-118 (CSM-118) for the mission arrived in KSC’s Manned Spacecraft and Operations Building (MSOB) on Feb. 10, 1973, where engineers placed it inside a vacuum chamber. The prime and backup crews conducted altitude tests of the CSM in early August. With the thruster problems aboard the Skylab 3 spacecraft docked to the space station, managers accelerated the processing flow for the Skylab 4 vehicle to enable a launch as early as Sept. 9 in case they had to implement a rescue mission. Workers mated CSM-118 to the Saturn rocket on Aug. 10 and rolled the stack to Launch Pad 39B four days later. By this time, the need for a rescue had diminished and the processing flow readjusted to enable a launch on need within nine days until the Skylab 3 splashdown on Sept. 25. Normal processing then resumed for a planned Nov. 9 launch, later adjusted to Nov. 11. Carr, Gibson, and Pogue entered their preflight health stabilization plan quarantine on Oct. 20. On Nov. 6, workers found hairline cracks in the mounting brackets of the Saturn IB’s stabilizing fins, requiring a slip of the launch date to Nov. 16 to complete their replacement at the pad. The Skylab 4 countdown began on Nov. 14, the day after the astronauts arrived at KSC.

Liftoff of Skylab 4
Liftoff of Skylab 4!

The third and final mission to the Skylab space station got underway on Nov. 16, 1973, with a thunderous liftoff from KSC’s Launch Pad 39B. Although officially planned as a 56-day mission for several years, mission managers had confidence of an extension to 84 days and planned accordingly, with the astronauts bringing additional food, supplies, and science experiments.

Eight hours after launch, and following two unsuccessful attempts, Carr hard docked the spacecraft to the space station. Pogue, who on Earth appeared resistant to all forms of motion sickness, developed a case of space motion sickness during the crew’s first evening, requiring several days to fully recover. This incident along with an overly packed timeline caused the astronauts to fall behind in accomplishing their tasks as they adjusted to weightlessness and learned their way around the large space station. The astronauts spent their first night in space aboard the Command Module, opening the hatch the next morning to begin reactivating Skylab. To their surprise, the station appeared to already have three occupants. As a joke, before they left the station in September, the Skylab 3 crew stuffed their successors’ flight suits with used clothing and left them in strategic places throughout the workshop. Carr, Gibson, and Pogue began settling into the routine aboard Skylab, preparing meals, exercising, and starting the large number of experiments. They continued the science program begun by the previous two Skylab crews, including biomedical investigations on the effects of long-duration space flight on the human body, Earth observations using the Earth Resources Experiment Package (EREP), and solar observations with instruments mounted on the Apollo Telescope Mount (ATM). With the prediction earlier in the year that newly discovered Comet Kohoutek would make its closest approach to the Sun in late December, scientists added cometary observations to the crew’s already busy schedule. The astronauts brought a Far Ultraviolet Electronographic Camera, the backup to the instrument deployed on the Moon during Apollo 16, to Skylab especially for observations of the comet, and used it for cometary photography during two spacewalks added to the mission.

One of the lessons learned from the first two Skylab missions indicated that the onboard bicycle ergometer alone did not provide enough exercise to maintain leg and back muscle mass and strength. To remedy this problem, physician and Skylab support astronaut Dr. William E. Thornton designed a makeshift treadmill that the third crew brought with them to the station. The treadmill device consisted of a teflon-coated aluminum plate bolted to the floor of the workshop. Bungee cords attached to the floor and to the ergometer harness supplied the downward force for the back and leg muscles with the astronauts sliding over the teflon-coated plate while walking or jogging in stocking feet. Because the exercise provided quite a strenuous workout, the crew dubbed it “Thornton’s revenge.” They also increased the overall amount of time they spent exercising.

In addition to the heavy science experiment load, the astronauts spent the first week in orbit preparing for the first spacewalk of the mission. On Nov. 22, their seventh day in space and also Thanksgiving Day, Gibson and Pogue suited up and stepped outside the space station with Gibson exclaiming, “Boy, if this isn’t the great outdoors.” During this six-hour 33-minute spacewalk, they replaced film canisters in the ATM and deployed an experiment package on the ATM truss. They took photographs with a camera that had originally been intended for the airlock now blocked by the sunshade that the first crew deployed in May to help cool the station. Gibson and Pogue accomplished all the tasks planned for this first spacewalk. Back inside the station, the astronauts settled in for the first Thanksgiving meal in space. For their dinner, Carr selected prime rib, Gibson went with traditional turkey, and Pogue chose chicken.

Right: The Skylab 4 rescue vehicle at Launch Pad 39B.

The inclusion of two docking ports on the Skylab space station enabled an in-flight rescue capability for the first time in human spaceflight history. In case a failure of the docked CSM stranded the onboard three-person crew, a two-person crew would launch in a second Apollo spacecraft specially configured with two extra couches to return all five astronauts. For the first two Skylab missions, the rocket and spacecraft for the subsequent mission served as the potential rescue vehicle. The failure of two Service Module thruster groups during Skylab 3 nearly required the rescue capability. Since Skylab 4 was the final mission, NASA procured an additional Saturn IB rocket, SA-209, and Apollo spacecraft, CSM-119, for the rescue role. The spacecraft arrived at KSC on May 2, 1973, and workers placed it in storage in the MSOB. In September, the backup crew of Brand, Lenoir, and Lind completed altitude chamber tests with the CSM, although only Brand and Lenoir would fly any the rescue mission. The S-IVB second stage for Saturn IB SA-209 arrived at KSC on Jan. 12, 1972, and workers placed it in storage in the VAB. The S-IB first stage arrived on Aug. 20, 1973. Because only one Mobile Launcher included the milkstool to launch a Saturn IB, assembly of the rescue vehicle had to await its return from the launch pad the day after the Skylab 4 liftoff. Assembly of the rocket in the VAB began on Nov. 26, and workers topped the rocket off with the spacecraft four days later. The stacked vehicle rolled out to Launch Pad 39B on Dec. 3 where engineers prepared the vehicle so that after Dec. 20, it could support a launch within nine days, should the need arise. The vehicle remained at the pad until Feb. 14, 1974, six days after the Skylab 4 splashdown.

To add to their packed timeline, one of the station’s three control moment gyros (CMGs) failed the day after the first spacewalk. Skylab used CMGs to control the station’s attitude without expending precious attitude control gas, a non-renewable resource heavily depleted early in the station’s life. Engineers on the ground worked out a plan to control the station’s attitude using only the two working CMGs, thereby enabling completion of the remaining science, especially the Earth resource passes and comet Kohoutek observations. Pogue made the first measurements of Comet Kohoutek on Nov. 23 from inside the station using a photometric camera brought to Skylab especially to observe the comet. The astronauts practiced flying the Astronaut Maneuvering Unit, a precursor of the Manned Maneuvering Unit used during the space shuttle program to retrieve satellites, inside the large dome of the workshop.

On Dec. 13, the mission’s 28th day, program officials assessed the astronauts’ performance and the status of the station and fully expected that they could complete the nominal 56-day mission and most likely the full 84 days. Despite being overworked and often behind the timeline, Carr, Gibson, and Pogue had already accomplished 84 hours of solar observations, 12 Earth resources passes, 80 photographic and visual Earth observations, all of the scheduled medical experiments, as well as numerous other activities such as student experiments, and science demonstrations. The astronaut’s major concern centered around the timelining process that had not given them time to adjust to their new environment and did not take into account their on-orbit daily routine. Despite the crew sending taped verbal messages to the ground asking for help in fixing these issues, the problem persisted. Skylab 4 Lead Flight Director Neil B. Hutchinson later admitted that the ground team learned many lessons about timelining long duration missions during the first few weeks of Skylab 4.

Cube Quest Concludes: Wins, Lessons Learned from Centennial Challenge

Small satellites, called CubeSats, are shown secured inside NASA’s Orion stage adapter at NASA’s Kennedy Space Center in Florida on Aug. 5, 2021. One of these CubeSats belonged to Team Miles, one of the three finalists in the Cube Quest Centennial Challenge. The ring-shaped stage adapter was connected to the Space Launch System’s Interim Cryogenic Propulsion Stage, with the Orion spacecraft secured on top. The CubeSats’ mission was to detach from the stage adapter, then fly near and beyond the Moon to conduct a variety of science experiments and technology demonstrations to expand our knowledge of the lunar surface during the Artemis I mission.

Artemis I launched from NASA’s Kennedy Space Center in Florida on Nov. 16, 2022, penning a new era of space exploration and inching the agency closer to sending the first woman and first person of color to the lunar surface.

Aboard the Space Launch System (SLS) rocket were 10 small satellites, no bigger than shoeboxes, whose goal was to detach and capably perform operations near and beyond the Moon. One of those satellites was a product of the Cube Quest Challenge, a NASA-led prize competition that asked citizen innovators to design, build, and deliver flight-qualified satellites called CubeSats that could perform its mission independently of the Artemis I mission.

Cube Quest is the agency’s first in-space public prize competition. Opened in 2015, the challenge began with four ground-based tournaments, which awarded almost $500,000 in prizes. Three finalists emerged from the ground competition with a ticket to hitch a ride aboard the SLS as a secondary payload – and win the rest of the competition’s $5 million prize purse, NASA’s largest-ever prize offering to date – in 2022.

Of the three finalists, Team Miles was the sole team to make the trip on Artemis I successfully. Shortly after a successful deployment in space, controllers detected downlink signals and processed them to confirm whether the CubeSat was operational. This remains the latest update for the Team Miles CubeSat.

“We’re still celebrating the many wins that were borne out of Cube Quest,” said Centennial Challenges Program Manager Denise Morris. “The intent of the challenge was to reward citizen inventors who successfully advance the CubeSat technologies needed for operations on the Moon and beyond, and I believe we accomplished this.”

Innovation rarely comes without error, but according to Challenge Manager Naveen Vetcha, who supports Centennial Challenges through Jacobs Space Exploration Group, even after everything goes as expected, there is no guarantee that scientists will reach their desired outcomes.

“Given the magnitude of what we can and do accomplish every day at NASA, it comes with the territory that not every test, proposal, or idea will come out with 100 percent success,” Vetcha said. “We have set ambitious goals, and challenging ourselves to change what’s possible will inevitably end with examples of not meeting our stretch goals. But, with each failure comes more opportunities and lessons to carry forward. In the end, our competitors created technologies that will enable affordable deep space CubeSats, which, to me, is a big win.”

Advancements in Commercial Space Research

Although Team Miles may have made it furthest in the Cube Quest Challenge, having launched its CubeSat as a secondary payload aboard Artemis I, the team continues to participate in the challenge long after launch.

“From Team Miles, Miles Space LLC was created and is still in business,” said Jan McKenna, Team Miles’ project manager and safety lead. “Miles Space is developing and selling the propulsion system designed for our craft to commercial aerospace companies, and we’ve expanded to be able to create hardware for communications along with our CubeSat developments.”

The next steps for Miles Space LLC include seeing through their active patent applications, establishing relationships with potential clients, and continuing to hunt for a connection with their flying CubeSat. Another finalist team, Cislunar Explorers, is currently focused on using their lessons learned to benefit the global small satellite community.

“I utilized the contacts I made through Cube Quest and the other Artemis Secondary Payloads for my thesis research,” said Aaron Zucherman, Cislunar Explorers’ project manager. “This has enabled me to find partnerships and consulting work with other universities and companies where I have shared my experiences learning the best ways to build interplanetary CubeSats.”

Inspiring a Generation of Space Scientists

This challenge featured teams from diverse educational and commercial backgrounds. Several team members credited the challenge as a catalyst in their graduate thesis or Ph.D. research, but one young innovator says Cube Quest completely redirected his entire career trajectory.

Project Selene team lead, Braden Oh, competed with his peers at La Cañada High School in La Cañada, California. Oh’s team eventually caught the attention of Kerri Cahoy at the Massachusetts Institute of Technology, and the designs were similar enough that Cahoy invited the two teams to merge. The exposure gained through this partnership was a powerful inspiration for Oh and his peers.

“I originally intended to apply to college as a computer science major, but my experiences in Cube Quest inspired me to study engineering instead,” Oh said. “I saw similar stories unfold for a number of my teammates; one eventually graduated from MIT and another now works for NASA.”

Cube Quest is managed out of NASA’s Ames Research Center in California’s Silicon Valley. The competition is a part of NASA’s Centennial Challenges, which is housed at the agency’s Marshall Space Flight Center in Huntsville, Alabama. Centennial Challenges is a part of NASA’s Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate.
