Following the historic year of 1969 that saw two successful Moon landings, 1970 opened on a more sober note. Ever-tightening federal budgets forced NASA to rescope its future lunar landing plans. The need for a Saturn V to launch an experimental space station in 1972 forced the cancellation of the final Moon landing mission and an overall stretching out of the Moon landing flights. Apollo 13 slipped to April, but the crew of James Lovell, Thomas “Ken” Mattingly, and Fred W. Haise and their backups John Young, John “Jack” Swigert, and Charles Duke continued intensive training for the landing at Fra Mauro. Training included practicing their surface excursions and water egress, along with time in spacecraft simulators. The three stages of the Apollo 14 Saturn V arrived at the launch site and workers began the stacking process for that mission now planned for October 1970. Scientists met in Houston to review the preliminary findings from their studies of the lunar samples returned by Apollo 11.
Apollo Program Changes
Apollo Moon landing plans in early 1970, with blue indicating completed landings, green planned landings at the time, and red canceled landings. Illustration of the Apollo Applications Program, later renamed Skylab, experimental space station then planned for 1972. On Jan. 4, 1970, NASA Deputy Administrator George Low announced the cancellation of Apollo 20, the final planned Apollo Moon landing mission. The agency needed the Saturn V rocket that would have launched Apollo 20 to launch the Apollo Applications Program (AAP) experimental space station, renamed Skylab in February 1970. Since previous NASA Administrator James Webb had precluded the building of any additional Saturn V rockets in 1968, this proved the only viable yet difficult solution.
In other program changes, on Jan. 13 NASA Administrator Thomas Paine addressed how NASA planned to deal with ongoing budgetary challenges. Lunar landing missions would now occur every six months instead of every four, and with the slip of Apollo 13 to April, Apollo 14 would now fly in October instead of July. Apollo 15 and 16 would fly in 1971, then AAP would launch in 1972, and three successive crews would spend, 28, 56, and 56 days aboard the station. Lunar landing missions would resume in 1973, with Apollo 17, 18, and 19 closing out the program by the following year.

Wernher von Braun in his office at NASA Headquarters in Washington, D.C. In addition to programmatic changes, several key management changes took place at NASA in January 1970. On Nov. 26, 1969, Christopher Kraft , the director of flight operations at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston, assumed the position of MSC deputy director. On Dec. 28, MSC Director Robert Gilruth named Sigurd “Sig” Sjoberg, deputy director of flight operations since 1963, to succeed Kraft. At NASA Headquarters in Washington, D.C., Associate Administrator for Manned Space Flight George Mueller resigned his position effective Dec. 10, 1969. To replace Mueller, on Jan. 8, NASA Administrator Paine named Dale Myers, vice president and general manager of the space shuttle program at North American Rockwell Corporation. On Jan. 27, Paine announced that Wernher von Braun, designer of the Saturn family of rockets and director of the Marshall Space Flight Center in Huntsville, Alabama, since its establishment in 1960, would move to NASA Headquarters and assume the position of deputy associate administrator for planning.
Apollo 11 Lunar Science Symposium

Between Jan. 5 and 8, 1970, several hundred scientists, including all 142 U.S. and international principal investigators provided with Apollo 11 samples, gathered in downtown Houston’s Albert Thomas Exhibit and Convention Center for the Apollo 11 Lunar Science Conference. During the conference, the scientists discussed the chemistry, mineralogy, and petrology of the lunar samples, the search for carbon compounds and any evidence of organic material, the results of dating of the samples, and the results returned by the Early Apollo Surface Experiments Package (EASEP). Senior NASA managers including Administrator Paine, Deputy Administrator Low, and Apollo Program Director Rocco Petrone attended the conference, and Apollo 11 astronaut Edwin “Buzz” Aldrin gave a keynote speech at a dinner reception. The prestigious journal Science dedicated its Jan. 30, 1970, edition to the papers presented at the conference, dubbing it “The Moon Issue”. The Lunar Science Conference evolved into an annual event, renamed the Lunar and Planetary Science Conference in 1978, and continues to attract scientists from around the world to discuss the latest developments in lunar and planetary exploration.

Engineers there completed a thorough inspection of the spacecraft and eventually prepared it for public display. NASA transferred Yankee Clipper to the Smithsonian Institution in 1973, and today the capsule resides at the Virginia Air & Space Center in Hampton, Virginia. NASA also released from quarantine the lunar samples and the parts of the Surveyor 3 spacecraft returned by the Apollo 12 astronauts. The scientists received their allocated samples in mid-February, while after initial examination in the Lunar Receiving Laboratory (LRL) the Surveyor parts arrived at NASA’s Jet Propulsion Laboratory in Pasadena, California, for detailed analysis.
Apollo 13
As the first step in the programmatic rescheduling of all Moon landings, on Jan. 7, NASA announced the delay of the Apollo 13 launch from March 12 to April 11. The Saturn V rocket topped with the Apollo spacecraft had rolled out the previous December to Launch Pad 39A where workers began tests on the vehicle. The prime crew of Lovell, Mattingly, and Haise, and their backups Young, Swigert, and Duke, continued to train for the 10-day mission to land in the Fra Mauro region of the Moon.

Apollo 13 prime crew members Lovell, Mattingly, and Haise completed their water egress training in the Gulf of Mexico near the coast of Galveston, Texas, on Jan. 24. With support from the Motorized Vessel Retriever, the three astronauts entered a boilerplate Apollo CM. Sailors lowered the capsule into the water, first in the Stable 2 or apex down position. Three self-inflating balloons righted the spacecraft into the Stable 1 apex up position within a few minutes. With assistance from the recovery team, Lovell, Mattingly, and Haise exited the spacecraft onto a life raft. A helicopter lifted them out of the life rafts using Billy Pugh nets and returned them to Retriever. Later that day, the astronauts returned to the MSC to examine Moon rocks in the LRL that the Apollo 12 astronauts had returned the previous November.
During their 33.5 hours on the Moon’s surface, Lovell and Haise planned to conduct two four-hour spacewalks to set up the Apollo Lunar Surface Experiment Package (ALSEP), a suite of five investigations designed to collect data about the lunar environment after the astronauts’ departure, and to conduct geologic explorations of the landing site. Mattingly planned to remain in the Command and Service Module (CSM), conducting geologic observations from lunar orbit including photographing potential future landing sites. Lovell and Haise conducted several simulations of the spacewalk timelines, including setting up the ALSEP equipment, practicing taking core samples, and photographing their activities for documentation purposes. They and their backups conducted practice sessions with the partial gravity simulator, also known as POGO, an arrangement of harnesses and servos that simulated walking in the lunar one-sixth gravity. Lovell and Young completed several flights in the Lunar Landing Training Vehicle (LLTV) that simulated the flying characteristics of the Lunar Module (LM) for the final several hundred feet of the descent to the surface.

In the LRL, technicians prepared the Apollo Lunar Sample Return Containers (ALSRC), or rock boxes, for Apollo 13. Like all missions, Apollo 13 carried two ALSRCs, with each box and lid manufactured from a single block of aluminum. Workers placed sample containers and bags and two 2-cm core sample tubes inside the two ALSRCs. Once loaded, technicians sealed the boxes under vacuum conditions so that they would not contain pressure greater than lunar ambient conditions. Engineers at MSC prepared the American flag that Lovell and Haise planned to plant on the Moon for stowage on the LM’s forward landing strut.

As part of the rescheduling of Moon missions, NASA delayed the launch of the next flight, Apollo 14, from July to October 1970. The CSM and the LM had arrived at NASA’s Kennedy Space Center (KSC) in Florida late in 1969 and technicians conducted tests on the vehicles in the Manned Spacecraft Operations Building (MSOB). On Jan. 12, workers lowered the ascent stage of the LM onto the CSM to perform a docking test – the next time the two vehicles docked they would be on the way to the Moon and the test verified their compatibility. Workers mated the two stages of the LM on Jan. 20.

The three stages of the Apollo 14 Saturn V arrived in KSC’s cavernous Vehicle Assembly Building (VAB) in mid-January and while workers stacked the first stage on its Mobile Launch Platform on Jan. 14, they delayed stacking the remainder of the rocket stages until May 1970. That decision proved fortunate, since engineers needed to modify the second stage engines following the pogo oscillations experienced during the Apollo 13 launch.

A team led by project design engineer William Creasy developed the MET based on recommendations from the first two Moon landing crews on how to improve efficiency on the lunar surface. Creasy and his team demonstrated the MET to Sally LaMere, editor of The Roundup, MSC’s employee newsletter. Three support astronauts, William Pogue, Anthony “Tony” England, and Gordon Fullerton tested the MET prototype in simulated one-sixth lunar gravity during parabolic aircraft flights.

This photomontage shows tubes containing samples from Mars, as collected by NASA’s Perseverance Mars rover. The agency’s Mars Sample Return Program plans to bring these samples back to study them in state-of-the-art facilities on Earth.Credit: NASA/JPL-Caltech/MSSS To maximize chances of successfully bringing the first Martian rock and sediment samples to Earth for the benefit of humanity, NASA announced Tuesday a new approach to its Mars Sample Return Program. The agency will simultaneously pursue two landing architectures, or strategic plans, during formulation, encouraging competition and innovation, as well as cost and schedule savings.
NASA plans to later select a single path forward for the program, which aims to better understand the mysteries of the universe, and to help determine whether the Red Planet ever hosted life. NASA is expected to confirm the program – and its design – in the second half of 2026.
“Pursuing two potential paths forward will ensure that NASA is able bring these samples back from Mars with significant cost and schedule saving compared to the previous plan,” said NASA Administrator Bill Nelson. “These samples have the potential to change the way we understand Mars, our universe, and – ultimately – ourselves. I’d like to thank the team at NASA and the strategic review team, led by Dr. Maria Zuber, for their work.”
In September 2024, the agency accepted 11 studies from the NASA community and industry on how best to return Martian samples to Earth. A Mars Sample Return Strategic Review team was charged with assessing the studies and then recommending a primary architecture for the campaign, including associated cost and schedule estimates.
“NASA’s rovers are enduring Mars’ harsh environment to collect ground-breaking science samples,” said Nicky Fox, who leads NASA’s Science Mission Directorate. “We want to bring those back as quickly as possible to study them in state-of-the-art facilities. Mars Sample Return will allow scientists to understand the planet’s geological history and the evolution of climate on this barren planet where life may have existed in the past and shed light on the early solar system before life began here on Earth. This will also prepare us to safely send the first human explorers to Mars.”
During formulation, NASA will proceed with exploring and evaluating two distinct means of landing the payload platform on Mars. The first option will leverage previously flown entry, descent, and landing system designs, namely the sky crane method, demonstrated with the Curiosity and Perseverance missions. The second option will capitalize on using new commercial capabilities to deliver the lander payload to the surface of Mars.
For both potential options, the mission’s landed platform will carry a smaller version of the Mars Ascent Vehicle. The platform’s solar panels will be replaced with a radioisotope power system that can provide power and heat through the dust storm season at Mars, allowing for reduced complexity.
The orbiting sample container will hold 30 of the sample tubes containing samples the Perseverance lander has been collecting from the surface of Mars. A redesign of the sample loading system on the lander, which will place the samples into the orbiting sample container, simplifies the backward planetary protection implementation by eliminating the accumulation of dust on the outside of the sample container.
Both mission options rely on a capture, containment and return system aboard ESA’s (European Space Agency’s) Earth Return Orbiter to capture the orbiting sample container in Mars orbit. ESA is evaluating NASA’s plan.

As 1969, an historic year that saw not just one but two successful human lunar landings, drew to a close, NASA continued preparations for its planned third Moon landing mission, Apollo 13, then scheduled for launch on March 12, 1970. The Apollo 13 prime crew of Commander James A. Lovell, Command Module Pilot (CMP) Thomas K. “Ken” Mattingly, and Lunar Module Pilot (LMP) Fred W. Haise, and their backups John W. Young, John L. “Jack” Swigert, and Charles M. Duke, continued intensive training for the mission. NASA announced the selection of the Fra Mauro region of the Moon as the prime landing site for Apollo 13, favored by geologists because it forms an extensive geologic unit around Mare Imbrium, the largest lava plain on the Moon. The Apollo 13 Saturn V rolled out to its launch pad.

Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrinhad returned from their Giantstep Presidential goodwill tour on Nov. 5, 1969. Due to scheduling conflicts, a visit to Canada could not be included in the same time frame as the rest of the tour, so the astronauts made a special trip to Ottawa and Montreal on Dec. 2 and 3, meeting with local officials.

He received standing ovations and spent much time shaking hands with the troops. The USO troupe also visited the hospital ship U.S.S. Sanctuary (AH-17) stationed in the South China Sea.
Apollo 12
For the first time in nearly four weeks, on Dec. 10, Apollo 12 astronauts Charles “Pete” Conrad, Richard F. Gordon, and Alan L. Bean stepped out into sunshine and breathed unfiltered air. Since their launch on Nov. 14, 1969, the trio had traveled inside their spacecraft for 10 days on their mission to the Moon and back, wore respirators during their recovery in the Pacific Ocean, stayed in the Mobile Quarantine Facility during the trip from the prime recovery ship U.S.S. Hornet back to Houston, and lived in the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston. Like the Apollo 11 crew before them, Conrad, Gordon, and Bean exhibited no symptoms of any infections with lunar microorganisms and managers declared them fit to be released from quarantine. MSC Director Robert L. Gilruth, other managers, and a crowd of well-wishers greeted Conrad, Gordon, and Bean.

Addressing the crowd gathered outside the LRL, Conrad commented that “the LRL was really quite pleasant,” but all three were glad to be breathing non man-made air! While the men went home to their families for a short rest, work inside the LRL continued. Scientists began examining the first of the 75 pounds of rocks returned by the astronauts as well as the camera and other hardware they removed from Surveyor 3 for effects of 31 months exposed to the harsh lunar environment. Preliminary analysis of the TV camera that failed early during their first spacewalk on the lunar surface indicated that the failure was due to partial burnout of the Videocon tube, likely caused by the crew accidentally pointing the camera toward the Sun. Other scientists busied themselves with analyzing the data returning from the Apollo Lunar Surface Experiment Package (ALSEP) instruments Conrad and Bean deployed on the lunar surface. Mission planners examining the photographs taken from lunar orbit of the Fra Mauro area were confident that the next mission, Apollo 13, would be able to make a safe landing in that geologically interesting site, the first attempt to land in the lunar highlands.

Gordon address a large group of well-wishers outside the Lunar Receiving Laboratory. Bean, left, Gordon, and Conrad during their postflight press conference. Two days after leaving the LRL, Conrad, Gordon, and Bean held their postflight press conference in the MSC auditorium. Addressing the assembled reporters, the astronauts first introduced their wives as their “number one support team,” then provided a film and photo summary of their mission, and answered numerous questions. Among other things, the astronauts praised the spacesuits they wore during the Moon walks, indicating they worked very well and, looking ahead, saw no impediments to longer excursions on future missions. Their only concern centered around the ever-present lunar dust that clung to their suits, raising that as a potential issue for future lunar explorers.

Conrad, Gordon, and Bean returned to NASA’s Kennedy Space Center (KSC) in Florida on Dec. 17, where their mission began more than a month earlier and nearly ended prematurely when lightning twice struck their Saturn V rocket. KSC Director Kurt H. Debus presented each astronaut with a framed photograph of their launch in front of 8,000 workers assembled in the Vehicle Assembly Building (VAB). Of their nearly ill-fated liftoff Conrad expressed his signature confidence, “Had we to do it again, I would launch exactly under the same conditions.” Guenter Wendt and his pad closeout team had collected a piece of grounding rod from the umbilical tower, cut it into three short pieces, mounted them with the inscription “In fond memory of the electrifying launch of Apollo 12,” and presented them to the astronauts. Three days later, President Richard M. Nixon and First Lady Pat Nixon welcomed Conrad, Gordon, and Bean and their wives Jane, Barbara, and Sue, respectively, to a dinner at the White House. After dinner, they watched a film about the Apollo 12 mission as well as the recently released motion picture Marooned about three astronauts stranded in space. President Nixon requested that the astronauts pay a visit to former President Lyndon B. Johnson, who for many years championed America’s space program, and brief him on their mission, which they did in January 1970.

An estimated 150,000 people lined the streets of the city to welcome Bean and his crewmates, dumping a blizzard of ticker tape and shredded office paper on the astronauts and their families during the parade. City workers cleared an estimated 60 tons of paper from the streets after the event.

On Dec. 10, 1969, NASA announced the selection of the Fra Mauro region of the Moon as the prime landing site for Apollo 13, located about 110 miles east of the Apollo 12 touchdown point. Geologists favored the Fra Mauro area for exploration because it forms an extensive geologic unit around Mare Imbrium, the largest lava plain on the Moon. Unlike the Apollo 11 and 12 sites located in the flat lunar maria, Fra Mauro rests in the relatively more rugged lunar highlands. The precision landing by the Apollo 12 crew and their extensive orbital photography of the Fra Mauro region gave NASA confidence to attempt a landing at Fra Mauro. Workers in KSC’s VAB had stacked the three stages of Apollo 13’s Saturn V in June and July 1969. On Dec. 10, they topped the rocket with the Apollo 13 spacecraft, comprising the Command and Service Modules (CSM) and the Lunar Module (LM) inside the Spacecraft LM Adapter. Five days later, the Saturn V exited the VAB and made the 3.5-mile journey out to Launch Pad 39A to begin a series of tests to prepare it for the launch of the planned 10-day lunar mission. During their 33.5 hours on the Moon’s surface, Lovell and Haise planned to conduct two four-hour spacewalks to set up the ALSEP, a suite of five investigations designed to collect data about the lunar environment after the astronauts’ departure, and to conduct geologic explorations of the landing site. Mattingly planned to remain in the CSM, conducting geologic observations from lunar orbit including photographing potential future landing sites.
Apollo 13 astronaut James A. Lovell trains on the deployment of the S-band antenna. Apollo 13 astronaut Fred W. Haise examines one of the lunar surface instruments. During the first of the two spacewalks, Apollo 13 Moon walkers Lovell and Haise planned to deploy the five ALSEP experiments, comprising:
Charged Particle Lunar Environment Experiment (CPLEE) – flying for the first time, this experiment sought to measure the particle energies of protons and electrons reaching the lunar surface from the Sun. Lunar Atmosphere Detector (LAD) – this experiment used a Cold Cathode Ion Gauge (CCIG) to measure the pressure of the tenuous lunar atmosphere. Lunar Heat Flow Experiment (LHE) – designed to measure the steady-state heat flow from the Moon’s interior. Passive Seismic Experiment (PSE) – similar to the device left on the Moon during Apollo 12, consisted of a sensitive seismometer to record Moon quakes and other seismic activity. Lunar Dust Detector (LDD) – measured the amount of dust deposited on the lunar surface. A Central Station provided command and communications to the ALSEP experiments, while a Radioisotope Thermoelectric Generator using heat from the radioactive decay of a Plutonium-238 sample provided uninterrupted power. Additionally, the astronauts planned to deploy and retrieve the Solar Wind Collector experiment to collect particles of the solar wind, as did the Apollo 11 and 12 crews before them.

Crosland of the National Park Service in Hawaii provided the astronauts with a tour of recent volcanic eruption sites in the Kilauea area, with the thought that the Fra Mauro formation might be of volcanic origin. During several traverses in the Kilauea Volcano area, NASA geologists John W. Dietrich, Uel S. Clanton, and Gary E. Lofgren and US Geological Survey geologists Gordon A. “Gordie” Swann, M.H. “Tim” Hait, and Leon T. “Lee” Silver accompanied the astronauts. The training sessions honed the astronauts’ geology skills and refined procedures for collecting rock samples and for documentary photography.

Apollo 14 astronauts Commander Alan B. Shepard, CMP Stuart A. Roosa, and LMP Edgar D. Mitchell and their backups Eugene A. Cernan, Ronald E. Evans, and Joe H. Engle had already begun training for their mission. At KSC’s Manned Spacecraft Operations Building (MSOB), the Apollo 14 CSM arrived from its manufacturer North American Rockwell in Downey, California, as did the two stages of the LM from the Grumman Aerospace and Engineering Company in Bethpage, New York, in November 1969. Engineers began tests of the spacecraft shortly after their arrival. The three stages of the Apollo 14 Saturn V were scheduled to arrive at KSC in January 1970.

In November 1969, Apollo 12 astronauts Commander Charles “Pete” Conrad, Command Module Pilot (CMP) Richard F. Gordon, and Lunar Module Pilot (LMP) Alan L. Bean completed the second crewed lunar landing mission. Conrad and Bean achieved a pinpoint landing in the Ocean of Storms within walking distance of the Surveyor 3 spacecraft that landed there in April 1967. While Gordon conducted science from lunar orbit, Conrad and Bean completed two spacewalks on the lunar surface, deploying science instruments, collecting geology samples, and inspecting Surveyor including retrieving several of it parts for study back on Earth. Preparations continued for the next two missions, Apollo 13 and 14, tentatively planned for March and July 1970, respectively.

Lift off came precisely at 11:22 a.m. EST on Nov. 14, 1969, with the Saturn V launching Apollo 12 into a dark and rainy sky. The flight proceeded normally for the first 36 seconds, with Conrad even commenting that, “It’s a lovely liftoff. It’s not bad at all.” Then everything went haywire. With Apollo 12 at about 6,600 feet altitude and flying through clouds, observers on the ground noted lightning striking the launch pad. Onboard the spacecraft, the astronauts saw a bright flash, followed by many of the spacecraft’s electronics going offline, causing the three power-generating fuel cells to also go offline.
A second event 52 seconds into the flight caused the spacecraft guidance navigation system to go offline. In the Mission Control Center (MCC) at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston, a young engineer named John W. Aaron monitored the spacecraft’s systems through the two incidents. He correctly deduced that the spacecraft’s Signal Conditioning Equipment (SCE) must have suffered some unknown upset and went offline. The simple solution to restoring it to normal function involved moving a seldom-used switch from its Normal to its Auxiliary position. Bean recalled the switch’s location on his panel, carried out the requested action, and restored the spacecraft’s systems. Aaron’s quick action saved the launch from two lightning strikes. Once Conrad understood the cause of the excitement, he radioed to Houston, “I think we need to do a little more all-weather testing.”

Middle: During Transposition and Docking, the LM Intrepid still attached to the S-IVB third stage. Right: The receding Earth during the translunar coast.
The rest of the ascent continued without incident and Apollo 12 settled into orbit around the Earth. After verifying that all systems continued functioning properly following the lightning strikes, the astronauts received the call, “The good word is you’re Go for TLI,” the Trans Lunar Injection, the second burn of the third stage engine to send them on their way to the Moon. In his characteristic fashion, Conrad replied, “Hoop-ee-doo! We’re ready! We didn’t expect anything else!” The next major event, the Transposition and Docking (T&D) maneuver, began about 25 minutes later.
After the separation of the Command and Service Module (CSM) Yankee Clipper from the S-IVB stage, Gordon turned it around and slowly guided it to a docking with the LM Intrepid still attached to the top of the S-IVB. Conrad commented during the maneuver, “I got an awful pretty looking Intrepid sitting out the window here, gang. We’ll go get her.” After the docking, Gordon backed away from the third stage, extracting the LM in the process, and completing the T&D maneuver. For the next three days, the astronauts continued their journey toward the Moon. Along the way, they inspected Intrepid to verify it came to no harm from the lightning strikes, conducted one midcourse maneuver to ensure their accurate arrival near the Moon, and provided two TV broadcasts showing views of Earth and their spacecraft.

The Apollo 12 astronauts awoke for their fourth mission day to find themselves within the Moon’s gravitational sphere of influence. Apollo 12 sailed behind the Moon, losing contact with Earth. Thirteen minutes later, the astronauts fired the Service Propulsion System (SPS) engine for the Lunar Orbit Insertion burn, placing them into an elliptical orbit around the Moon.

During the third lunar orbit, the crew fired the SPS engine again to circularize their orbit. The next day, Conrad and Bean donned their spacesuits and reactivated the LM for the separation and landing, extending Intrepid’s landing legs. After undocking and while behind the Moon, Conrad and Bean fired the LM’s Descent Propulsion System engine to lower Intrepid’s orbit. Exactly half a revolution later, Intrepid began the burn to drop it from orbit all the way to the landing in the Ocean of Storms. With Bean providing updates from the guidance computer, Conrad skillfully piloted Intrepid to a smooth landing just northwest of Surveyor Crater, and as they learned later, only 538 feet from Surveyor 3. Without much fanfare, Conrad and Bean completed the postlanding checklist, although Bean allowed himself a little exuberant “Good landing, Pete! Outstanding, man! Beautiful!” Conrad radioed to Mission Control, “Okay, we’re in hot shape, Houston. We’re in real good shape!” They had a chance to look out the windows, with Bean exclaiming, “Holy cran, it’s beautiful out here!” Conrad replied, “It sure is; it’s something else,” later adding, “Man! I can’t wait to get outside!”

Conrad and Bean donned their Portable Life Support System (PLSS) backpacks that provided oxygen and communications while on the surface and donned their helmets and gloves. They depressurized the LM, opened the hatch, and Conrad backed out onto the porch, slowly climbing down the ladder. Halfway down, he pulled a lanyard that deployed a color TV camera on the side of the LM’s descent stage, providing a view of him on the LM ladder. After he jumped from the bottom rung onto the footpad, Conrad exclaimed, “Whoopie! Man, that may have been a small one for Neil, but that’s a long one for me,” in reference to Armstrong’s famous words as he took humanity’s first step on the Moon and Conrad’s shorter stature. As he stepped off the pad, he remarked, “Oooh is that soft and queasy.” After taking a few tentative steps, Conrad informed everyone that he could see Surveyor 3 sitting inside the crater. He collected the contingency sample – in case they had to leave quickly due to an emergency, geologists would have one small sample from the Ocean of Storms.
Bean joined Conrad on the surface, both acclimating rapidly to working in one-sixth g. Conrad set up the S-band antenna for communications with Earth, but while setting up the TV camera, Bean accidentally pointed it at the Sun and damaged the vidicon tube, ending the live TV transmission from the Moon. Bean deployed the Solar Wind Collector (SWC), a Swiss experiment that collected particles from the solar wind, and then he and Conrad set up the American flag. They began the primary task of the first spacewalk – setting up the various instruments of the Apollo Lunar Surface Experiment Package (ALSEP). Conrad and Bean carried them to their deployment location about 430 feet to the northwest of Intrepid. They explored the area around the ALSEP site, visiting craters of interest and collecting rock and soil samples before heading back toward Intrepid. They remarked on several occasions how the lunar dust clung to their suits and equipment, and as Conrad quipped, “We’re going to be a couple of dirty boogers.” First Bean then Conrad climbed up the ladder and once inside Intrepid they closed the hatch and repressurized the cabin. Their first spacewalk lasted 3 hours and 56 minutes. They set up hammocks in Intrepid and went to sleep.
Left and middle: Charles “Pete” Conrad and Alan L. Bean with the Surveyor 3 spacecraft, with their Lunar Module (LM) Intrepid visible in the background. Right: View from inside the LM through Bean’s window following the second spacewalk.
After a short night’s rest, Conrad and Bean prepared for their second spacewalk. As before, first Conrad and then Bean descended the ladder to the surface. Conrad walked to the ALSEP to inspect one of the instruments, the seismometer they deployed during the first spacewalk picking up his footsteps. Both then headed west from Intrepid, where Conrad rolled two rocks down into a crater, the vibrations captured by the seismometer. They collected several documented samples, often preceded with expressions like “Oooooh!” and “That’s a beauty!” and dug a trench to expose subsurface material, collecting a sample from about eight inches deep.
They set off toward the main objective of this spacewalk – Surveyor 3, resting on the inner slope of 600-foot-wide Surveyor Crater. Entering the crater from the south rim, they walked counterclockwise while descending down the slope until they reached the robotic spacecraft. After taking “tourist” pictures with Surveyor, the two photographed the craft from all angles, noting that the trenches left by its scoop and the marks from its footpads when it bounced after landing looked as fresh as when Surveyor photographed them in 1967. Using cutters, Conrad removed the craft’s camera, scoop, and other parts for return to Earth, where engineers and scientists examined them for the effects of 31 months in the harsh lunar environment. The work at Surveyor completed, the two returned to Intrepid. Bean retrieved the SWC experiment, overcoming difficulties in rolling it back up. Compared with a short 77-minute exposure during Apollo 11, this SWC collected samples of the solar wind for nearly 19 hours. With everything packed up, Bean followed by Conrad headed up the ladder. After closing the hatch, they repressurized Intrepid, ending the 3-hour 49-minute excursion.

After returning inside Intrepid, Conrad and Bean took photographs out the windows, showing the signs of their visit – numerous footprints, the American flag, the S-band antenna, and in the distance, the ALSEP station. As Gordon in Yankee Clipper flew overhead on his 30th lunar revolution, Intrepid’s Ascent Stage engine ignited, and Conrad and Bean lifted off from the Moon after 31 hours and 31 minutes on the surface. Conrad exclaimed, “Liftoff! And away we go!” with Bean adding, “Boy, did it fire!” Intrepid and Yankee Clipper executed a series of maneuvers that led to their docking about three and a half hours after liftoff from the Moon. Their independent flights had lasted 37 hours and 42 minutes. The three astronauts opened the hatches between the two spacecraft and began transfers from Intrepid into Yankee Clipper, including the lunar samples, cameras, and film. Gordon transferred some unneeded items to be jettisoned in Intrepid. The transfers completed, they closed the hatches between the spacecraft and jettisoned the LM. To calibrate the seismometer left on the Moon, controllers sent a command to Intrepid to fire its thrusters to drop it out of orbit and send it crashing onto the surface. The seismometer recorded signals for nearly one hour after the impact.

The primary activity for their remaining time around the Moon consisted of photographing potential landing sites for future Apollo missions, such as the Fra Mauro highlands and the Descartes region. On their 45th revolution, they went around to the Moon’s back side for the last time and they fired the SPS for the Trans Earth Injection burn. Apollo 12 left lunar orbit after 3 days 17 hours and 2 minutes. Conrad radioed to Mission Control, “Hello, Houston. Apollo 12’s en route home.”
During the three-day return trip to Earth, the astronauts conducted a midcourse maneuver to refine their trajectory, answered questions from geologists and other scientists, and held a press conference at the end of which they held up a homemade sign to the camera that read, “Yankee Clipper sailed with Intrepid to the Sea of Storms, Moon, November 14, 1969,” signed by all three crew members. With the Sun and the Earth nearly aligned, the astronauts could only see a very thin crescent of their home planet, prompting Conrad to comment, “Houston, we just got our first glimpse of you this morning, and there’s not very much of you out there.”

Right: Image taken by a recovery diver of the decontamination officer assisting Alan L. Bean out of Yankee Clipper, with Richard F. Gordon, left, and Charles “Pete” Conrad already aboard the life raft.
Shortly before reentry, orbital mechanics had a show in store for the astronauts – their trajectory passed through the Earth’s shadow, treating them to a total solar eclipse. Gordon radioed Mission Control, “We’re getting a spectacular view at eclipse,” and Bean added that it was a “fantastic sight.” The excitement of the eclipse over, the astronauts prepared the cabin for reentry. The CM separated from the Service Module and rotated to point its heatshield into the direction of flight. At 400,000 feet, Yankee Clipper now travelling at 24,625 miles per hour encountered the first tendrils of Earth’s atmosphere. About four minutes of radio blackout followed as ionized gases created by the heat of reentry surrounded the spacecraft. As Apollo 12 came out of the blackout, the prime recovery ship U.S.S. Hornet established radar contact with the spacecraft at a distance of 119 miles. At about 24,000 feet, the spacecraft jettisoned its apex cover, then deployed its two drogue parachutes to slow and stabilize the capsule. At 10,000 feet, the three main orange and white parachutes deployed, with Conrad reporting, “Three gorgeous beautiful chutes.” Precisely 244 hours and 36 minutes after lifting off from Florida, Apollo 12 splashed down in the Pacific Ocean less than four miles from Hornet, bringing the second lunar landing mission to a successful conclusion.

Middle: Conrad, front, Gordon, and Bean walk from the helicopter to the Mobile Quarantine Facility (MQF). Right: Admiral John S. McCain addresses the Apollo 12 astronauts in the MQF.
The capsule assumed the apex down Stable 2 position in the water, but in less than five minutes three self-inflating balloons righted the spacecraft into the Stable 1 upright orientation. Five minutes later, a helicopter dropped the first three recovery team swimmers into the water, tasked with securing a flotation collar and rafts to the spacecraft. Decontamination officer Ernest “Ernie” L. Jahncke next dropped into the water and once the crew opened the hatch, he handed them fresh flight suits and respirators. A few minutes later, the crew reopened the hatch, and first Conrad, then Gordon, and finally Bean climbed aboard a life raft where Jahncke used a disinfectant solution to decontaminate the astronauts and the spacecraft. The recovery helicopter lowered a Billy Pugh net to haul the astronauts up from the raft, first Gordon, then Bean, and finally Conrad. Aboard the helicopter, NASA flight surgeon Dr. Clarence A. Jernigan gave each astronaut a brief physical examination during the short flight back to Hornet, declaring all three healthy.
After it landed on Hornet’s deck, sailors lowered the helicopter to the hangar deck, where Conrad, Gordon, and Bean, followed by Dr. Jernigan, walked the few steps to the Mobile Quarantine Facility (MQF) where NASA engineer Brock R. “Randy” Stone awaited them. He sealed the door of the MQF exactly one hour after splashdown. The five men spent the next five days together in the MQF until they arrived at the Lunar Receiving Laboratory (LRL) at MSC. The astronauts took congratulatory phone calls from President Richard M. Nixon, who field-promoted all three from U.S. Navy Commanders to Captains, and from NASA Administrator Thomas O. Paine. After the astronauts talked briefly with their families, Commander-in-Chief of Pacific Naval Forces Admiral John S. McCain formally welcomed them back to Earth, followed by brief speeches by Rear Admiral Donald C. Davis, Commander of Recovery Forces, and Capt. Carl J. Seiberlich, Hornet’s skipper.

Within an hour after the astronauts arrived on board Hornet, the recovery team hauled Yankee Clipper out of the water and towed it below to the hangar deck next to the MQF. As Hornet set sail for Pearl Harbor, arriving there four days later, workers attached a hermetically sealed plastic tunnel between the MQF and Yankee Clipper, allowing Stone to leave the MQF and open the hatch to the capsule without breaking the biological barrier. He retrieved the two rock boxes containing the lunar samples, the bags containing the Surveyor parts, film cassettes, and mission logs from the capsule. He brought them to the MQF where he sealed them in plastic bags and transferred them to the outside through a transfer lock that included a decontamination wash.
Outside the MQF, NASA engineers placed these items into transport containers and loaded them aboard two separate aircraft. The first aircraft carrying one rock box and a second package containing film departed Hornet within nine hours of the recovery, flying to Pago Pago, American Samoa. From there the two containers were placed aboard a cargo aircraft and flown directly to Ellington Air Force Base (AFB) near MSC in Houston, arriving there late in the afternoon of Nov. 25. A second aircraft departed Hornet 14 hours after the first and included the second rock box, additional film as well as the astronaut medical samples. It flew to Pago Pago where workers transferred the containers to another cargo plane that flew them to Houston. Less than 48 hours after splashdown, scientists in the LRL were examining the lunar samples and processing the film.

Meanwhile, in the Pacific Ocean, Hornet sailed for Pearl Harbor, Hawaii, with the astronauts inside the MQF to maintain the strict back-contamination protocols. They also celebrated Thanksgiving on Nov. 27. Dr. Jernigan conducted regular medical examinations of the astronauts, who showed no ill effects from their ten-day spaceflight or any signs of infection by any lunar microorganisms. The crew members availed themselves of one amenity aboard the MQF that was a novelty at the time – a microwave oven for meal preparation.
On Nov. 28, Hornet arrived at Pearl Harbor. Workers lifted the MQF with the astronauts inside onto a flat-bed trailer. After a brief welcoming ceremony including traditional Hawaiian flower leis, ukulele music, and hula dancers, they drove the MQF to nearby Hickam AFB, where Air Force personnel loaded it onto a cargo aircraft. After an eight-hour flight, the aircraft arrived at Ellington on the morning of Nov. 29, where the MQF was offloaded in front of a waiting crowd of well-wishers including MSC Director Robert R. Gilruth and Apollo 11 astronaut Neil A. Armstrong. The astronauts’ wives and children were on hand to welcome them home to Houston. Workers placed the MQF on a flat-bed truck and drove it to the LRL. Less than two hours after landing in Houston the astronauts arrived inside the Crew Reception Area (CRA) where they spent the next 11 days. During their time in quarantine, they completed many of the postflight debriefs and examined the lunar rocks as well as the parts of Surveyor 3 such as its camera that they returned from the Ocean of Storms.

After the astronauts departed Hornet in Pearl Harbor, workers lifted Yankee Clipper from the carrier’s flight deck to the dock and drove it to Hickam AFB where technicians safed the vehicle by draining its toxic fuels. To preserve back-contamination protocols, Yankee Clipper’s hatch remained sealed. On Dec. 1, workers loaded Yankee Clipper onto a cargo aircraft at Hickam AFB. It arrived at Ellington AFB the next day and workers trucked it to the LRL, then towed it inside the spacecraft room of the CRA. The Apollo 12 astronauts signed their names on the capsule below the same words they held up during their inflight news conference – “Yankee Clipper Sailed with Intrepid to The Ocean of Storms, Moon, November 14, 1969.”

The next Moon landing mission, Apollo 13, planned to launch on March 12, 1970, and visit the Fra Mauro highlands region of the Moon. With the mission’s increased emphasis on science, geology training for the Apollo 13 prime crew of Commander James A. Lovell, CMP Thomas K. “Ken” Mattingly, and LMP Fred W. Haise, and their backups John W. Young, Jack L. Swigert, and Charles M. Duke, took on greater importance. Lovell, Haise, Young, and Duke, accompanied by several geologists, traveled to Kilbourne Hole, New Mexico, for a one-day geology field trip on Nov. 11. The area’s volcanic origins served as appropriate training for their planned landing site, then believed to be a result of volcanic activity. The astronauts practiced deploying their ALSEP set of instruments, including during suited tests in a vacuum chamber in MSC’s Space Environment Simulation Laboratory. At KSC, workers in the Manned Spacecraft Operations Building (MSOB) continued preparing both the CSM and the LM for Apollo 13 prior to stacking with the Saturn V rocket in December.

President John F. Kennedy’s national commitment to land a man on the Moon and return him safely to the Earth before the end of the decade posed multiple challenges, among them how to train astronauts to land on the Moon, a place with no atmosphere and one-sixth the gravity on Earth. The Lunar Landing Research Vehicle (LLRV) and its successor the Lunar Landing Training Vehicle (LLTV) provided the training tool to simulate the final 200 feet of the descent to the lunar surface. The ungainly aircraft made its first flight on Oct. 30, 1964, at NASA’s Flight Research Center (FRC), now NASA’s Armstrong Flight Research Center (AFRC) in California. The Apollo astronauts who completed landings on the Moon attributed their successes largely to training in these vehicles.
The first Lunar Landing Research Vehicle silhouetted against the rising sun on the dry lakebed at Edwards Air Force Base in California’s Mojave Desert.
In December 1961, NASA Headquarters in Washington, D.C., received an unsolicited proposal from Bell Aerosystems in Buffalo, New York, for a design of a flying simulator to train astronauts on landing a spacecraft on the Moon. Bell’s approach, using their design merged with concepts developed at NASA’s FRC, won approval and the space agency funded the design and construction of two Lunar Landing Research Vehicles (LLRV). At the time of the proposal, NASA had not yet chosen the method for getting to and landing on the Moon, but once NASA decided on Lunar Orbit Rendezvous in July 1962, the Lunar Module’s (LM) flying characteristics matched Bell’s proposed design closely enough that the LLRV served as an excellent trainer.
Two views of the first Lunar Landing Research Vehicle shortly after its arrival and prior to assembly at the Flight Research Center, now NASA’s Armstrong Flight Research Center, in California.
Bell Aerosystems delivered the LLRV-1 to FRC on April 8, 1964, where it made history as the first pure fly-by-wire aircraft to fly in Earth’s atmosphere. Its design relied exclusively on an interface with three analog computers to convert the pilot’s movements to signals transmitted by wire and to execute his commands. The open-framed LLRV used a downward pointing turbofan engine to counteract five-sixths of the vehicle’s weight to simulate lunar gravity, two rockets provided thrust for the descent and horizontal translation, and 16 LM-like thrusters provided three-axis attitude control. The astronauts could thus simulate maneuvering and landing on the lunar surface while still on Earth. The LLRV pilot could use an aircraft-style ejection seat to escape from the vehicle in case of loss of control.

Right: NASA chief test pilot Joseph “Joe” A. Walker, left, demonstrates the features of LLRV-1 to President Lyndon B. Johnson during his visit to FRC.
Engineers conducted numerous tests to prepare the LLRV for its first flight. During one of the engine tests, the thrust generated was higher than anticipated, lifting crew chief Raymond White and the LLRV about a foot off the ground before White could shut off the engines. On June 19, during an official visit to FRC, President Lyndon B. Johnson inspected the LLRV featured on a static display. The Secret Service would not allow the President to sit in the LLRV’s cockpit out of an overabundance of caution since the pyrotechnics were installed, but not yet armed, in the ejection seat. Following a Preflight Readiness Review held Aug. 13 and 14, managers cleared the LLRV for its first flight.
Left: NASA chief test pilot Joseph “Joe” A. Walker during the first flight of the Lunar Landing Research Vehicle (LLRV). Right: Walker shortly after the first LLRV flight.
In the early morning of Oct. 30, 1964, FRC chief pilot Joseph “Joe” A. Walker arrived at Edwards Air Force Base’s (AFB) South Base to attempt the first flight of the LLRV. Walker, a winner of both the Collier Trophy and the Harmon International Trophy, had flown nearly all experimental aircraft at Edwards including 25 flights in the X-15 rocket plane. On two of his X-15 flights, Walker earned astronaut wings by flying higher than 62 miles, the unofficial boundary between the Earth’s atmosphere and space. After strapping into the LLRV’s ejection seat, Walker ran through the preflight checklist before advancing the throttle to begin the first flight. The vehicle rose 10 feet in the air, Walker performed a few small maneuvers and then made a soft landing after having flown for 56 seconds. He lifted off again, performed some more maneuvers, and landed again after another 56 seconds. On his third flight, the vehicle’s electronics shifted into backup mode and he landed the craft after only 29 seconds. Walker seemed satisfied with how the LLRV handled on its first flights.

Walker took LLRV-1 aloft again on Nov. 16 and eventually completed 35 test flights with the vehicle. Test pilots Donald “Don” L. Mallick, who completed the first simulated lunar landing profile flight during the LLRV’s 35th flight on Sept. 8, 1965, and Emil E. “Jack” Kluever, who made his first flight on Dec. 13, 1965, joined Walker to test the unique aircraft. Joseph S. “Joe” Algranti and Harold E. “Bud” Ream, pilots at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center (JSC) in Houston, travelled to FRC to begin training flights with the LLRV in August 1966. Workers at FRC assembled the second vehicle, LLRV-2, during the latter half of 1966. In December 1966, after 198 flights workers transferred LLRV-1 to Ellington AFB near MSC for the convenience of astronaut training, and LLRV-2 followed in January 1967 after completing six test flights at FRC. The second LLRV made no further flights, partly because the three Lunar Landing Training Vehicles (LLTVs), more advanced models that better simulated the LM’s flying characteristics, began to arrive at Ellington in October 1967. Neil A. Armstrong completed the first astronaut flights aboard LLRV-1 on Mar. 23, 1967, and flew 21 flights before ejecting from the vehicle on May 6, 1968, seconds before it crashed. He later completed his lunar landing certification flights using LLTV-2 in June 1969, one month before peforming the actual feat on the Moon.

Middle: Apollo 12 Commander Charles “Pete” Conrad prepares to fly LLTV-2 in July 1969. Right: Apollo 14 Commander Alan B. Shepard flies LLTV-3 in December 1970.
All Apollo Moon landing mission commanders and their backups completed their lunar landing certifications using the LLTV, and all the commanders attributed their successful landings to having trained in the LLTV. Apollo 8 astronaut William A. Anders, who along with Armstrong completed some of the early LLRV test flights, called the training vehicle “a much unsung hero of the Apollo program.” During the flight readiness review in January 1970 to clear LLTV-3 for astronaut flights, Apollo 11 Commander Armstrong and Apollo 12 Commander Charles “Pete” Conrad, who had by then each completed manual landings on the Moon, spoke positively of the LLTV’s role in their training. Armstrong’s overall impression of the LLTV: “All the pilots … thought it was an extremely important part of their preparation for the lunar landing attempt,” adding “It was a contrary machine, and a risky machine, but a very useful one.” Conrad emphasized that were he “to go back to the Moon again on another flight, I personally would want to fly the LLTV again as close to flight time as possible.” During the Apollo 12 technical debriefs, Conrad stated the “the LLTV is an excellent training vehicle for the final phases. I think it’s almost essential. I feel it really gave me the confidence that I needed.” During the postflight debriefs, Apollo 14 Commander Alan B. Shepard stated that he “did feel that the LLTV contributed to my overall ability to fly the LM during the landing.”

David R. Scott, Apollo 15 commander, stated in the final mission report that “the combination of visual simulations and LLTV flying provided excellent training for the actual lunar landing. Comfort and confidence existed throughout this phase.” In the Apollo 15 postflight debrief, Scott stated that he “felt very comfortable flying the vehicle (LM) manually, because of the training in the LLTV, and there was no question in my mind that I could put it down where I wanted to. I guess I can’t say enough about that training. I think the LLTV is an excellent simulation of the vehicle.” Apollo 16 Commander John W. Young offered perhaps the greatest praise for the vehicle just moments after landing on the lunar surface: “Just like flying the LLTV. Piece of cake.” Young reiterated during the postflight debriefs that “from 200 feet on down, I never looked in the cockpit. It was just like flying the LLTV.” Apollo 17 Commander Eugene A. Cernan stated in the postflight debrief that “the most significant part of the final phases from 500 feet down, … was that it was extremely comfortable flying the bird. I contribute (sic) that primarily to the LLTV flying operations.”

In addition to playing a critical role in the Moon landing program, these early research and test vehicles aided in the development of digital fly-by-wire technology for future aircraft. LLRV-2 is on display at the Air Force Flight Test Museum at Edwards AFB (on loan from AFRC). Visitors can view LLTV-3 suspended from the ceiling in the lobby of the Teague Auditorium at JSC.
The monograph Unconventional, Contrary, and Ugly: The Lunar Landing Research Vehicle provides an excellent and detailed history of the LLRV.
