      In September 1969, celebrations continued to mark the successful first human Moon landing two months earlier, and NASA prepared for the next visit to the Moon. The hometowns of the Apollo 11 astronauts held parades in their honor, the postal service recognized their accomplishment with a stamp, and the Smithsonian put a Moon rock on display. They addressed Congress and embarked on a 38-day presidential round the world goodwill tour. Eager scientists received the first samples of lunar material to study in their laboratories. Meanwhile, NASA prepared Apollo 12 for November launch as the astronauts trained for the mission with an increased emphasis on lunar science. Plans called for additional Moon landings in 1970, with spacecraft under construction and astronauts in training.
      Apollo 11
      For Apollo 11 astronauts Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin, their busy August 1969 postflight schedule continued into September with events throughout the United States and beyond. These included attending hometown parades, dedicating a stamp to commemorate their historic mission, unveiling a display of a Moon rock they collected, addressing a Joint Meeting of Congress, and visiting contractor facilities that built parts of their rocket and spacecraft. They capped off the hectic month with their departure, accompanied by their wives, on a presidential round-the-world goodwill tour that lasted into early November.

      On Sep. 6, each astronaut appeared at hometown events held in their honor. Apollo 11 Commander Armstrong’s hometown of Wapakoneta, Ohio, welcomed him with a parade and other events.  Montclair, New Jersey, held a parade to honor hometown hero Lunar Module Pilot (LMP) Aldrin. And New Orleans, Louisiana, the adopted hometown of Command Module Pilot (CMP) Michael Collins, honored him with a parade.

      Three days later, the astronauts reunited in Washington, D.C., where they appeared at the dedication ceremony of a new postage stamp that honored their mission. The U.S. Postal Service had commissioned artist Paul Calle in 1968 to design the stamp. The Apollo 11 astronauts had carried the stamp’s master die to the Moon aboard the Lunar Module (LM) Eagle and after its return to Earth the Postal Service used it to make the printing pages for the 10¢ postage stamp. At the National Postal Forum, Armstrong, Collins, and Aldrin unveiled the stamp together with Postmaster General Winton M. Blount, and each astronaut received an album with 30 of the “First Man on the Moon” stamps. On Sep. 15, the crew returned to Washington to present a two-pound rock they collected in the Sea of Tranquility during their historic Moon walk to Frank A. Taylor, the Director General of Museums at the Smithsonian Institution in Washington, D.C. The rock went on public display two days later at the Smithsonian’s Arts and Industries Building, the first time the public could view a Moon rock.

      With their wives observing from the Visitors Gallery of the House of Representatives, on Sep. 16 Armstrong, Aldrin, and Collins addressed a Joint Meeting of Congress. In this same chamber in May 1961, President John F. Kennedy committed the nation to land a man on the Moon and return him safely to the Earth before the end of decade. In a sense, the astronauts reported on the safe and successful completion of that challenge. Speaker of the House John W. McCormack introduced the astronauts to the gathering, as Vice President Spiro T. Agnew looked on. Each astronaut reflected on the significance of the historic mission.
      Armstrong noted that their journey truly began in the halls of Congress when the Space Act of 1958 established NASA. Aldrin commented that “the Apollo lesson is that national goals can be met when there is a strong enough will to do so.” Collins shared a favorite quotation of his father’s to describe the value of the Apollo 11 mission: “He who would bring back the wealth of the Indies must take the wealth of the Indies with him.” Armstrong closed with, “We thank you, on behalf of all the men of Apollo, for giving us the privilege of joining you in serving – for all mankind.” After their speeches, the astronauts presented one American flag each to Vice President Agnew in his role as President of the Senate and to Speaker McCormack. The flags, that had flown over the Senate and House of Representatives, had traveled to the Moon and back with the astronauts. Speaker McCormack recognized the astronauts’ wives Jan Armstrong, Joan Aldrin, and Pat Collins for their contributions to the success of the Apollo 11 mission.

      On Sep. 26, Armstrong and Collins visited two facilities in California of North American Rockwell (NAR) Space Division, the company that built parts of the Saturn V rocket and Apollo 11 spacecraft. First, they stopped at the Seal Beach plant that built the S-II second stage of the rocket, where 3,000 employees turned out to welcome them. Armstrong commented to the assembled crowd that during the July 16, 1969, liftoff, “the S-II gave us the smoothest ride ever.” Collins added that despite earlier misgivings about using liquid hydrogen as a rocket fuel, “after the ride you people gave us, I sure don’t have doubts any longer.” About 7,000 employees greeted the two astronauts and showered them with confetti at their next stop, the facility in Downey that built the Apollo Command and Service Modules. Both Armstrong and Collins thanked the team for building an outstanding spacecraft that took them to the Moon and returned them safely to Earth. The astronauts inspected the Command Module (CM) for Apollo 14, then under construction at the plant.
      On the morning of Sep. 29, a blue and white Boeing VC-137B presidential jet touched down at Ellington Air Force Base in Houston. Neil and Jan Armstrong, Buzz and Joan Aldrin, and Mike and Pat Collins boarded the plane and joined their entourage of State Department and NASA support personnel. They departed Houston for Mexico City, the first stop on the Apollo 11 Giantstep goodwill world tour. They didn’t return to the United States until Nov. 5, having visited 29 cities in 24 countries, just nine days before Apollo 12 took off on humanity’s second journey to land on the Moon.

      Distribution of Apollo 11 lunar samples to scientists at the Lunar Receiving Laboratory at the Manned Spacecraft Center, now NASA’s Johnson Space Center in Houston.
      Back in Houston, distribution to scientists of samples of the lunar material returned by the Apollo 11 astronauts began on Sep. 17 at the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. Daniel H. Anderson, curator of lunar samples at the LRL, supervised the distribution of approximately 18 pounds – about one-third of the total Apollo 11 lunar material – to 142 principal investigators from the United States and eight other countries according to prior agreements. The scientists examined the samples at their home institutions and reported their results at a conference in Houston in January 1970. They returned to the LRL any of the samples not destroyed during the examination process.
      Apollo 12
      In September 1969, NASA continued preparations for the second Moon landing mission, Apollo 12, scheduled for launch on Nov. 14. The Apollo 12 mission called for a pinpoint landing in Oceanus Procellarum (Ocean of Storms) near where the robotic spacecraft Surveyor 3 had touched down in April 1967. They planned to stay on the lunar surface for about 32 hours, compared to Apollo 11’s 21 hours, and conduct two surface spacewalks totaling more than 5 hours. During the first of their two excursions, the astronauts planned to deploy the Apollo Lunar Surface Experiments Package (ALSEP) and collect lunar samples. During the second spacewalk, they planned to visit Surveyor 3 and remove some of its equipment for return to Earth and collect additional lunar samples. The Apollo 12 prime crew of Commander Charles “Pete” Conrad, CMP Richard F. Gordon, and LMP Alan L. Bean and their backups David R. Scott, Alfred M. Worden, and James B. Irwin continued intensive training for the mission.

Right: Apollo 12 astronauts Alan L. Bean, left, Richard F. Gordon, and Charles “Pete” Conrad pose in front of their Saturn V during the rollout to the pad.
      On Sep. 8, the Saturn V rocket with the Apollo 12 spacecraft on top rolled out from Kennedy Space Center’s (KSC) Vehicle Assembly Building to Launch Pad 39A. The rocket made the 3.5-mile trip to the pad in about 6 hours, with Conrad, Gordon, and Bean on hand to observe the rollout. Workers at the pad spent the next two months thoroughly checking out the rocket and spacecraft to prepare it for its mission to the Moon. The two-day Flight Readiness Test at the end of September ensured that the launch vehicle and spacecraft systems were in a state of flight readiness. In addition to spending many hours in the spacecraft simulators, Conrad and Bean as well as their backups Scott and Irwin rehearsed their lunar surface spacewalks including the visit to Surveyor 3. Workers at NASA’s Jet Propulsion Laboratory in Pasadena, California, shipped an engineering model of the robotic spacecraft to KSC, and for added realism, engineers there mounted the model on a slope to match its relative position on the interior of the crater in which it stood on the Moon. Conrad and Scott used the Lunar Landing Training Vehicle (LLTV) at Ellington Air Force Base (AFB) near MSC to train for the final 200 feet of the descent to the lunar surface.

Middle: Conrad trains in the use of the Hasselblad camera he and Bean will use on the Moon. Right: Bean, left, and Conrad train with an engineering model of a Surveyor spacecraft.
      With regard to lunar geology training, the Apollo 12 astronauts had one advantage over their predecessors – they could inspect actual Moon rocks and soil returned by the Apollo 11 crew. On Sep. 19, Conrad and Bean arrived at the LRL, where Lunar Sample Curator Anderson met them. Anderson brought out a few lunar rocks and some lunar soil that scientists had already tested and didn’t require to be stored under vacuum or other special conditions, allowing Conrad and Bean to examine them closely and compare them with terrestrial rocks and soil they had seen during geology training field trips. This first-hand exposure to actual lunar samples significantly augmented Conrad and Bean’s geology training. To highlight the greater emphasis placed on lunar surface science, the Apollo 12 crews (prime and backup) went on six geology field trips compared to just one for the Apollo 11 crews.

Middle: Wearing Biological Isolation Garments and assisted by a decontamination officer, standing in the open hatch, Apollo 12 astronauts await retrieval in the life raft. Right: The recovery helicopter hoists the third crew member using a Billy Pugh net.
      Although the Apollo 11 astronauts returned from the Moon in excellent health and scientists found no evidence of any harmful lunar microorganisms, NASA managers still planned to continue the postflight quarantine program for the Apollo 12 crew members, their spacecraft, and the lunar samples they brought back. The first of these measures involved the astronauts donning Biological Isolation Garments (BIG) prior to exiting the spacecraft after splashdown. Since they didn’t carry the BIGs with them to the Moon and back, one of the recovery personnel, also clad in a BIG, opened the hatch to the capsule after splashdown and handed the suits to the astronauts inside, who donned them before exiting onto a life raft.
      On Sep. 20, the Apollo 12 astronauts rehearsed these procedures, identical to the ones used after the first Moon landing mission, in the Gulf of Mexico near Galveston, Texas, using a boilerplate Apollo CM and supported by the Motorized Vessel (MV) Retriever. As it turned out, NASA later removed the requirement for the crew to wear BIGs, and after their splashdown the Apollo 12 crew wore overalls and respirators.

Right: Apollo 13 backup crew members John W. Young, left, and Swigert in the CM for an altitude chamber test – Charles M. Duke is out of the picture at right.
      Preparations for Apollo 13 continued in parallel. In KSC’s Manned Spacecraft Operations Building (MSOB), Apollo 13 astronauts completed altitude chamber tests of their mission’s CM and LM. Prime crew members Commander James A. Lovell, CMP Thomas K. “Ken” Mattingly, and LMP Fred W. Haise completed the CM altitude test on Sep. 10, followed by their backups John W. Young, Jack L. Swigert, and Charles M. Duke on Sep. 17. The next day, Lovell and Haise completed the altitude test of the LM, followed by Young and Duke on Sep. 22. At the time of these tests, Apollo 13 planned to launch on March 12, 1970, on a 10-day mission to visit the Fra Mauro highlands region of the Moon. To prepare for their lunar surface excursions, Lovell, Haise, Young, and Duke, accompanied by geologist-astronaut Harrison H. “Jack” Schmitt and Caltech geologist Leon T. “Lee” Silver, spent the last week of September in Southern California’s Orocopia Mountains immersed in a geology boot camp.

Engle had started training for their mission planned for mid-year 1970. At the NAR facility in Downey, engineers prepared the CM and SM and shipped them to KSC in November 1969. Also at Downey, workers continued assembling the CM and SM planned for the Apollo 15 mission in late 1970. As events transpired throughout 1970, plans for those two missions changed significantly.

      On Sept. 25, NASA appointed veteran astronaut James A. McDivitt as the Manager of the Apollo Spacecraft Program Office at MSC. McDivitt, selected as an astronaut in 1962, commanded two spaceflights, Gemini IV in June 1965 that included the first American spacewalk and Apollo 9 in March 1969, the first test of the LM in Earth orbit. He succeeded George M. Low who, in that position since April 1967, led the agency’s efforts to recover from the Apollo 1 fire and originated the idea to send Apollo 8 on a lunar orbital mission. Under his tenure, NASA successfully completed five crewed Apollo missions including the first human Moon landing. MSC Director Robert R. Gilruth initially assigned Low to plan future programs until Nov. 13, when President Richard M. Nixon nominated him as NASA deputy administrator. The Senate confirmed Low’s nomination on Nov. 25, and NASA Administrator Thomas O. Paine swore him in on Dec. 3. Low filled the position vacant since March 20, 1969.

      The Apollo 11 mission in July 1969 completed the goal set by President John F. Kennedy in 1961 to land a man on the Moon and return him safely to the Earth before the end of the decade. At the time, NASA planned nine more Apollo Moon landing missions of increasing complexity and an Earth orbiting experimental space station. No firm human space flight plans existed once these missions ended in the mid-1970s. After taking office in 1969, President Richard M. Nixon chartered a Space Task Group (STG) to formulate plans for the nation’s space program for the coming decades. The STG’s proposals proved overly ambitious and costly to the fiscally conservative President who chose to take no action on them.

Right: President Lyndon B. Johnson addresses a crowd during a March 1968 visit to the Manned Spacecraft Center, now NASA’s Johnson Space Center, in Houston.
      On May 25, 1961, before a Joint Session of Congress, President John F. Kennedy committed the United States to the goal, before the decade was out, of landing a man on the Moon and returning him safely to the Earth. President Kennedy reaffirmed the commitment during an address at Rice University in Houston in September 1962. Vice President Lyndon B. Johnson, who played a leading role in establishing NASA in 1958, under Kennedy served as the Chair of the National Aeronautics and Space Council. Johnson worked with his colleagues in Congress to ensure adequate funding for the next several years to provide NASA with the needed resources to meet that goal.
      Following Kennedy’s assassination in November 1963, now President Johnson continued his strong support to ensure that his predecessor’s goal of a Moon landing could be achieved by the stipulated deadline. But with increasing competition for scarce federal resources from the conflict in southeast Asia and from domestic programs, Johnson showed less interest in any space endeavors to follow the Apollo Moon landings. NASA’s annual budget peaked in 1966 and began a steady decline three years before the agency met Kennedy’s goal. From a budgetary standpoint, the prospects of a vibrant, post-Apollo space program didn’t look all that rosy, the triumphs of the Apollo missions of 1968 and 1969 notwithstanding.

Middle: Proposed lunar landing sites through Apollo 20, per August 1969 NASA planning. Right: An illustration of the Apollo Applications Program experimental space station that later evolved into Skylab.
      Less than a month after assuming the Presidency in January 1969, Richard M. Nixon appointed a Space Task Group (STG), led by Vice President Spiro T. Agnew as the Chair of the National Aeronautics and Space Council, to report back to him on options for the American space program in the post-Apollo years. Members of the STG included NASA Acting Administrator Thomas O. Paine (confirmed by the Senate as administrator on March 20), the Secretary of Defense, and the Director of the Office of Science and Technology. At the time, the only approved human space flight programs included lunar landing missions through Apollo 20 and three long-duration missions to an experimental space station based on Apollo technology that evolved into Skylab.
      Beyond a general vague consensus that the United States human space flight program should continue, no approved projects existed once these missions ended by about 1975. With NASA’s intense focus on achieving the Moon landing within President Kennedy’s time frame, long-term planning for what might follow the Apollo Program garnered little attention. During a Jan. 27, 1969, meeting at NASA chaired by Acting Administrator Paine, a general consensus emerged that the next step after the Moon landing should involve the development of a 12-person earth-orbiting space station by 1975, followed by an even larger outpost capable of housing up to 100 people “with a multiplicity of capabilities.” In June, with the goal of the Moon landing almost at hand, NASA’s internal planning added the development of a space shuttle by 1977 to support the space station, the development of a lunar base by 1976, and the highly ambitious idea that the U.S. should prepare for a human mission to Mars as early as the 1980s. NASA presented these proposals to the STG for consideration in early July in a report titled “America’s Next Decades in Space.”

      Still bathing in the afterglow of the successful Moon landing, the STG presented its 29-page report “The Post-Apollo Space Program:  Directions for the Future” to President Nixon on Sep. 15, 1969, during a meeting at the White House. In its Conclusions and Recommendations section, the report noted that the United States should pursue a balanced robotic and human space program but emphasized the importance of the latter, with a long-term goal of a human mission to Mars before the end of the 20th century. The report proposed that NASA develop new systems and technologies that emphasized commonality, reusability, and economy in its future programs. To accomplish these overall objectives, the report presented three options:

      Option I – this option required more than a doubling of NASA’s budget by 1980 to enable a human Mars mission in the 1980s, establishment of a lunar orbiting space station, a 50-person Earth orbiting space station, and a lunar base. The option required a decision by 1971 on development of an Earth-to-orbit transportation system to support the space station. The option maintained a strong robotic scientific and exploration program.

      Option II – this option maintained NASA’s budget at then current levels for a few years, then anticipated a gradual increase to support the parallel development of both an earth orbiting space station and an Earth-to-orbit transportation system, but deferred a Mars mission to about 1986. The option maintained a strong robotic scientific and exploration program, but smaller than in Option I.

      Option III – essentially the same as Option II but deferred indefinitely the human Mars mission.
      In separate letters, both Agnew and Paine recommended to President Nixon to choose Option II.

      The White House released the report to the public at a press conference on Sep. 17 with Vice President Agnew and Administrator Paine in attendance. Although he publicly supported a strong human spaceflight program, enjoyed the positive press he received when photographed with Apollo astronauts, and initially sounded positive about the STG options, President Nixon ultimately chose not to act on the report’s recommendations.  Nixon considered these plans too grandiose and far too expensive and relegated NASA to one America’s domestic programs without the special status it enjoyed during the 1960s. Even some of the already planned remaining Moon landing missions fell victim to the budgetary axe.
      On Jan. 4, 1970, NASA had to cancel Apollo 20 since the Skylab program needed its Saturn V rocket to launch the orbital workshop. In 1968, then NASA Administrator James E. Webb had turned off the Saturn V assembly line and none remained beyond the original 15 built under contract. In September 1970, reductions in NASA’s budget forced the cancellation of two more Apollo missions, and  in 1971 President Nixon considered cancelling two more. He reversed himself and they flew as Apollo 16 and Apollo 17 in 1972, the final Apollo Moon landing missions.

      More than two years after the STG submitted its report, in January 1972 President Nixon directed NASA Administrator James C. Fletcher to develop the Space Transportation System, the formal name for the space shuttle, the only element of the recommendations to survive the budgetary challenges.  NASA anticipated the first orbital flight of the program in 1979, with the actual first flight occurring two years later. Twelve years elapsed after Nixon’s shuttle decision when President Ronald W. Reagan approved the development of a space station, the second major component of the STG recommendation.  14 years later, the first element of that program reached orbit. In those intervening years, NASA had redesigned the original American space station, leading to the development of a multinational orbiting laboratory called the International Space Station. Humans have inhabited the space station continuously for the past quarter century, conducting world class and cutting edge scientific and engineering research. Work on the space station helps enable future programs, returning humans to the Moon and later sending them on to Mars and other destinations.

      On Aug. 10, 1969, Apollo 11 astronauts Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin completed their 21-day quarantine after returning from the Moon. The historic nature of their mission resulted in a very busy postflight schedule for Armstrong, Collins, and Aldrin, starting with celebrations in New York, Chicago, Los Angeles, and Houston. Scientists continued to examine the lunar samples the Apollo 11 astronauts returned from the Sea of Tranquility. NASA set its sights on additional lunar landing missions, announcing plans for a pinpoint landing by Apollo 12 in November 1969 that also included visiting the robotic Surveyor 3 that landed on the Moon in 1967. The agency announced the crews for the Apollo 13 and 14 missions planned for 1970. Including prime and backup crews, NASA had 18 astronauts training for lunar landing missions. Support astronauts brought that number to 32.
      Apollo 11
      Following their return from the Moon, Armstrong, Collins, and Aldrin completed their 21-day quarantine in the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. During their stay in the LRL, they worked on their pilot reports, conducted postflight debriefs including with the Apollo 12 crew, and Armstrong celebrated his 39th birthday. On the evening of Aug. 10, they left the relative quiet of the LRL for a very hectic next few months. After spending a day reuniting with their families, the three reported back to their offices and held their postflight press conference on Aug. 12. The next day, they flew first to New York for a massive ticker tape parade, then on to Chicago for another big parade, ending the day in Los Angeles with a state dinner hosted by President Richard M. Nixon and attended by most active astronauts, members of Congress, 44 state governors, and 83 foreign ambassadors. They returned to Houston for a welcome home parade on Aug. 16, ending the day with a barbecue party and a tribute to the entire NASA team in the Astrodome, emceed by Frank Sinatra. Meanwhile, on Aug. 14, engineers shipped the Command Module Columbia to its manufacturer, the North American Rockwell plant in Downey, California, for postflight inspections. Scientists in the LRL eagerly continued their examinations of the 48 pounds of lunar material the Apollo 11 astronauts returned from the Sea of Tranquility.

      Apollo 12
      At the time Apollo 11 returned from its historic journey, NASA had plans for nine more Apollo Moon landing missions. On July 29, Apollo Program Director Samuel C. Phillips at NASA Headquarters in Washington, D.C., announced the launch date, Nov. 14, 1969, and the landing site, in the Ocean of Storms, for Apollo 12. The main goals of this second lunar landing included a precision touchdown near the Surveyor 3 spacecraft that landed there in April 1967, and an expanded science program conducted during two spacewalks, including the deployment of the first Apollo Lunar Surface Experiment Package (ALSEP), a suite of science instruments. The Apollo 12 prime crew of Commander Charles “Pete” Conrad, Command Module Pilot (CMP) Richard F. Gordon, and Lunar Module Pilot (LMP) Alan L. Bean and their backups David R. Scott, Alfred M. Worden, and James B. Irwin, began training after their assignment in April. In addition to rehearsing aspects of their flight in mission simulators, they practiced for the descent and precision landing, for the two spacewalks planned during their 31.5-hour lunar surface stay, including visiting and examining Surveyor 3, and for the expanded geology exploration. The latter included a three-day geology field trip to Hawaii with simulated lunar traverses. At NASA’s Jet Propulsion Laboratory in Pasadena, California, the astronauts received a detailed briefing on the Surveyor spacecraft. At NASA’s Kennedy Space Center (KSC) in Florida, workers had already assembled their Saturn V rocket, with rollout to Launch Pad 39A planned for early September. The U.S. Navy chose the U.S.S. Hornet (CVS-12), the carrier that successfully recovered Apollo 11, to reprise its role as prime recovery ship for Apollo 12.

      Apollo 13 and 14
      On Aug. 6, 1969, NASA announced the crews for Apollo 13 and 14, the third and fourth Moon landing missions. At the time of the announcement, Apollo 13 had a planned launch date in March 1970 and a proposed landing site at the Fra Mauro region in the lunar highlands, the first landing site not in the relatively flat lunar maria. Apollo 14 aimed for a July 1970 mission with the Crater Censorinus area in the lunar highlands to the southeast of the Sea of Tranquility as a tentative landing site. Plans for both missions called for two lunar surface excursions totaling about six hours with a lunar stay duration of 35 hours. As on Apollo 12, the crews planned to deploy an ALSEP suite of science instruments, in addition to conducting the geology field work of documenting and collecting rock and soil samples for return to scientists on Earth for analysis.

      The prime crew for Apollo 13 consisted of Commander James A. Lovell, CMP Thomas K. “Ken” Mattingly, and LMP Fred W. Haise. Lovell would make his fourth space mission aboard Apollo 13, having flown on Gemini VII and XII as well as orbiting the Moon during Apollo 8 – making him the first person to travel to the Moon twice. Neither Mattingly nor Haise had flown in space before, although Haise had served with Lovell on the Apollo 11 backup crew. The Apollo 13 backup crew consisted of John W. Young, John L. Swigert, and Charles M. Duke. Young had flown three previous missions, Gemini 3 and X and more recently aboard Apollo 10, the Moon landing dress rehearsal flight. Swigert and Duke had no spaceflight experience, although Duke served as capsule communicator during Apollo 10 as well as during the Apollo 11 Moon landing.

      Flight hardware for Apollo 13 had already arrived at KSC. Workers in the Vehicle Assembly Building (VAB) completed stacking of the three Saturn V rocket stages in High Bay 2 on July 31. They added a boilerplate Apollo spacecraft to the top of the rocket, and in a roll-around maneuver on Aug. 8, the stack left the VAB, crawled to the other side of the building, and rolled back inside to High Bay 1. North American Rockwell delivered the Command and Service Modules to KSC on June 26, where workers in the Manned Spacecraft Operations Building (MSOB) mated the two modules four days later in preparation for preflight testing in altitude chambers. The Lunar Module (LM) ascent and descent stages arrived at KSC on June 27 and 28, respectively, from their manufacturer, the Grumman Aircraft Corporation in Bethpage, New York. Following a docking test between the CM and LM, workers in the MSOB mated the two stages of the LM on July 15.

      NASA designated Commander Alan B. Shepard, CMP Stuart A. Roosa, and LMP Edgar D. Mitchell as the prime crew for Apollo 14. Shepard, the first American in space when he launched aboard his Freedom 7 spacecraft in May 1961, recently returned to flight status after a surgical intervention cured his Ménière’s disease, an inner ear disorder. Neither Roosa nor Mitchell had spaceflight experience. The backup crew consisted of Eugene A. Cernan, Ronald E. Evans, and Joe H. Engle. Cernan had flown in space twice before, on Gemini IX and more recently on Apollo 10. Evans and Engle had not flown in space before, although Engle earned astronaut wings as a pilot with the U.S. Air Force flying the X-15 rocket plane above the 50-mile altitude required to qualify as an astronaut on three of his 16 flights.

      The Apollo 14 astronauts jumped right into their geology training. On Aug. 14, Shepard, Mitchell, and Engle spent the day at the United States Geological Service’s (USGS) Crater Field near Flagstaff, Arizona, including getting a geologist’s lecture on the mechanisms of crater formation. On Aug. 22 and 23, Cernan joined them on a geology field trip to Idaho, where they visited Craters of the Moon National Monument, Butte Crater lava tubes, Ammon pumice quarries, and the Wapi volcanic fields. Geologists chose these sites for training because at the time Apollo 14 planned to visit a presumed volcanic area on the Moon.

Kraft, director of flight operations at MSC, seen here in Mission Control following the Apollo 11 splashdown, succeeded Trimble.
      Several changes in senior NASA leadership took place following Apollo 11. At NASA Headquarters in Washington, D.C., Phillips retired as Apollo Program Director, having served in that position since 1964, and returned to the U.S. Air Force. Rocco A. Petrone, director of launch operations at KSC since 1966, succeeded him. George S. Trimble announced his retirement as MSC deputy director effective Sept. 30, having served in that role since October 1967. In November 1969, MSC Director Robert R. Gilruth named Christopher C. Kraft to succeed Trimble as his deputy.

      On the eve of the 55th anniversary of the Apollo 11 Moon landing, NASA’s Johnson Space Center in Houston commemorated the unsung heroes who helped make humanity’s first steps on the Moon possible. 

      To celebrate their enduring legacy, Johnson named one of its central buildings the “Dorothy Vaughan Center in Honor of the Women of Apollo” on July 19, 2024, during a ceremony recognizing the early pioneers who laid the groundwork for the Artemis Generation. 
      NASA’s Johnson Space Center in Houston named one of its central building the “Dorothy Vaughan Center in Honor of the Women of Apollo.” NASA/David DeHoyos Dorothy Vaughan, a mathematician and NASA’s first Black manager, played a crucial role in this historic achievement. As the head of the West Area Computing Unit at Langley Research Center in Hampton, Virginia, from 1949 to 1958, she led her team in mastering new computer programming languages, helping to pave the way for the agency’s current diverse workforce and leadership. 

      The program included remarks from Johnson Director Vanessa Wyche, NASA astronaut Christina Koch, and Deputy Associate Administrator Casey Swails.

NASA/Robert Markowitz “Dorothy Vaughan, alongside all of our Women of Apollo, represents the best of NASA’s past, and their legacies serve as the inspiration and foundation for our future,” said Wyche. “As we prepare to take our next giant leap, the Women of Apollo will take each step with us.” 

      NASA leadership joined for the special occasion, including Associate Administrator Jim Free, Acting Associate Administrator for Space Technology Mission Directorate and Langley Director Clayton Turner, Director of NASA’s Stennis Space Center in Mississippi John Bailey, and former Johnson Director Mike Coats. Also in attendance were Reps. Lizzie Fletcher and Sylvia Garcia, and representatives from the offices of Sen. Ted Cruz, Sen. John Cornyn, and Rep. Brian Babin. 

      NASA astronauts Suni Williams, Jeanette J. Epps, and Tracy C. Dyson celebrated the historic moment with a special message from the International Space Station.  

      “We have accomplished our dreams of space exploration thanks to the many NASA women that paved the way for diversity, inclusion, and excellence,” said Epps.  

      “Building on the efforts of our space exploration pioneers, we continue to work for the benefit of humanity,” said Dyson. “NASA’s success is only possible because of the tenacity and expertise of individuals like Dorothy Vaughan whose legacy of brilliance continues to inspire us today.”
      Texas Southern University’s Dr. Thomas F. Freeman Debate Team delivers a speech during the building naming event. NASA/Robert Markowitz The program also featured the reading of a poem by Dr. Vivian Ayers Allen, a Pulitzer Prize-nominated poet, cultural activist, and former NASA editor and typist. The poem, titled “Hawk,” was published just 11 weeks before humankind’s first venture into space with Sputnik I as an allegory where space flight symbolizes freedom. Allen’s daughter, Phylicia Rashad, recited the poem ahead of the presentation by Texas Southern University’s Dr. Thomas F. Freeman Debate Team.

      ICON, shown in this artist’s concept, studied the frontiers of space, the dynamic zone high in our atmosphere where terrestrial weather from below meets space weather above. NASA/Goddard/Conceptual Image Lab NASA’s ICON mission studied the outermost layer of Earth’s atmosphere called the ionosphere. ICON provided critical insights into interplay between space weather and Earth’s weather. The mission gathered unprecedented detail of airglow, showed a relationship between the atmosphere’s ions and Earth’s magnetic field lines, and provided the first concrete observation to confirm Earth’s long-theorized ionospheric dynamo. Nearly a year after ICON accomplished its primary mission, communication was lost in November 2022 for unclear reasons. NASA formally concluded the mission after several months of troubleshooting could not regain contact. After contributing to many important findings on the boundary between Earth’s atmosphere and space, the Ionospheric Connection Explorer (ICON) mission has come to an end. ICON launched in October 2019 and after completing its two-year mission objectives in December 2021, it operated as an extended mission for another year.
      “The ICON mission has truly lived up to its name,” said Joseph Westlake, heliophysics division director at NASA Headquarters in Washington. “ICON not only successfully completed and exceeded its primary mission objectives, it also provided critical insights into the ionosphere and the interplay between space and terrestrial weather.”
      The ICON spacecraft studied a part of our planet’s outermost layer of the atmosphere, called the ionosphere. From there, ICON investigated what events impact the ionosphere, including Earth’s weather from below and space weather from above.
      The ionosphere is the lowest boundary of space, located between 55 miles to 360 miles above Earth’s surface. It is made up of a sea of particles that have been ionized, a mix of positively charged ions and negatively charged electrons called plasma. This frontier of space is a dynamic and busy region, home to many satellites — including the International Space Station — and is a conduit for radio communications and GPS signals.

      Video explaining the features of the ionosphere, Earth’s outmost layer of the atmosphere. It is home to the aurora, the International Space Station, a variety of satellites, and radio communication waves.
      NASA/Goddard/Conceptual Image Lab/Krystofer Kim Both satellites and signals can be disrupted by the complex interactions of terrestrial and space weather. Studying and understanding the ionosphere is crucial to understanding space weather and its effects on our technology.
      The ICON mission captured unprecedented data about the ionosphere with direct measurements of the charged gas in its immediate surroundings alongside images of one of the ionosphere’s most stunning features — airglow.
      ICON tracked the colorful bands as they moved through the ionosphere. Airglow is created by a process similar to what creates the aurora. However, airglow occurs around the world, not just the northern and southern latitudes where auroras are typically found. Although airglow is normally dim, ICON’s instruments were specially designed to capture even the faintest glow to build a picture of the ionosphere’s density, composition, and structure.
      The lowest reaches of space glow with bright bands of color called airglow. NASA Through the principle of Doppler shift, ICON’s sensitive imagers also detected the motion of the atmosphere as it glowed. “It’s like measuring a train’s speed by detecting the change in the pitch of its horn — but with light,” said Thomas J. Immel, ICON mission lead at the University of California, Berkeley. The mission was specifically designed to perform this technically difficult measurement.

      A New Ionospheric Perspective
      The ICON mission’s comprehensive view of the upper atmosphere provided valuable data for scientists to unravel for years to come. For instance, its measurements showed how the 2022 Hunga Tonga-Hunga Ha’apai volcanic eruption disrupted electrical currents in the ionosphere.
      “ICON was able to capture the speed of the volcanic eruption, allowing us to directly see how it affected the motion of charged particles in the ionosphere,” Immel said. “This was a clear example of the connection between tropical weather and ionospheric structure. ICON showed us how things that happen in terrestrial weather have a direct correlation with events in space.”
      Another scientific breakthrough was ICON’s measurements of the motion of ions in the atmosphere and their relationship with Earth’s magnetic field lines. “It was truly unique,” Immel remarked. “ICON’s measurements of the motion of ions in the atmosphere was scientifically transformational in our understanding of behavior in the ionosphere.”

When the wind changes direction, the ion fluctuation changes to flow downward.NASA’s Scientific Visualization Studio/William T. Bridgman With ICON’s help, scientists better understand how these interactions drive a process called the ionospheric dynamo. The dynamo, which lies at the bottom of the ionosphere, remained a mystery for decades because it is difficult to observe.
      ICON provided the first concrete observation of winds fueling the dynamo and how this influences space weather. Unpredictable terrestrial winds move plasma around the ionosphere, sending the charged particles shooting out into space or plummeting toward Earth. This electrically charged tug-of-war between the ionosphere and Earth’s electromagnetic fields acts as a generator, creating complex electric and magnetic fields that can affect both technology and the ionosphere itself.
      “No one had ever seen this before,” Immel said. “ICON finally and conclusively provided experimental confirmation of the wind dynamo theory.”

      An Iconic Legacy
      On Nov. 25, 2022, the ICON team lost contact with the spacecraft. Communication with the spacecraft could not be established, even after performing a power cycle reset using a built-in command loss timer. Though the spacecraft remains intact, other troubleshooting techniques were unable to re-establish contact between the ICON spacecraft and mission operators.
      “ICON’s legacy will live on through the breakthrough knowledge it provided while it was active and the vast dataset from its observations that will continue to yield new science,” Westlake said. “ICON serves as a foundation for new missions to come.”
