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 

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. 

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. 

Apollo 12 

On New Year’s Day 1970, Apollo 12 astronauts Charles “Pete” Conrad, Richard Gordon, and Alan Bean led the 81st annual Tournament of Roses Parade in Pasadena, California, as Grand Marshals. Actress June Lockhart, an avid space enthusiast, interviewed them during the TV broadcast of the event. As President Richard Nixon had earlier requested, Conrad, Gordon, and Bean and their wives paid a visit to former President Lyndon B. Johnson and First Lady Lady Bird Johnson at their ranch near Fredericksburg, Texas, on Jan. 14, 1970. The astronauts described their mission to the former President and Mrs. Johnson.  

Managers released the Apollo 12 Command Module (CM) Yankee Clipper from quarantine and shipped it back to its manufacturer, the North American Rockwell plant in Downey, California, on Jan. 12. 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. 

Apollo 14 

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. 

Apollo 14 astronauts Alan Shepard, Stuart Roosa, and Edgar Mitchell and their backups Eugene Cernan, Ronald Evans, and Joe Engle continued training for their mission. In addition to working in spacecraft simulators, Shepard, Mitchell, Cernan, and Engle conducted suited vacuum chamber runs in MSC’s Space Environmental Simulation Laboratory (SESL) and completed their first familiarization with deploying their suite of ALSEP investigations.  

The Apollo 14 astronauts made the first use of the Modular Equipment Transporter (MET), a golf-cart like wheeled conveyance to transport their tools and lunar samples. 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.

      NASA’s Electrodynamic Dust Shield (EDS) successfully demonstrated its ability to remove regolith, or lunar dust and dirt, from its various surfaces on the Moon during Firefly Aerospace’s Blue Ghost Mission 1, which concluded on March 16. Lunar dust is extremely abrasive and electrostatic, which means it clings to anything that carries a charge. It can damage everything from spacesuits and hardware to human lungs, making lunar dust one of the most challenging features of living and working on the lunar surface. The EDS technology uses electrodynamic forces to lift and remove the lunar dust from its surfaces. The first image showcases the glass and thermal radiator surfaces, coated in a layer of regolith. As you slide to the left, the photo reveals the results after EDS activation. Dust was removed from both surfaces, proving the technology’s effectiveness in mitigating dust accumulation.
      This milestone marks a significant step toward sustaining long-term lunar and interplanetary operations by reducing dust-related hazards to a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. The EDS technology is paving the way for future dust mitigation solutions, supporting NASA’s Artemis campaign and beyond. NASA’s Electrodynamic Dust Shield was developed at Kennedy Space Center in Florida with funding from NASA’s Game Changing Development Program, managed by the agency’s Space Technology Mission Directorate.

      A NASA F/A-18 research aircraft flies above California near NASA’s Armstrong Flight Research Center in Edwards, California, testing a commercial precision landing technology for future space missions. The Psionic Space Navigation Doppler Lidar (PSNDL) system is installed in a pod located under the right wing of the aircraft.NASA Nestled in a pod under an F/A-18 Hornet aircraft wing, flying above California, and traveling up to the speed of sound, NASA put a commercial sensor technology to the test. The flight tests demonstrated the sensor accuracy and navigation precision in challenging conditions, helping prepare the technology to land robots and astronauts on the Moon and Mars. 
      The Psionic Space Navigation Doppler Lidar (PSNDL) system is rooted in NASA technology that Psionic, Inc. of Hampton, Virginia, licensed and further developed. They miniaturized the NASA technology, added further functionality, and incorporated component redundancies that make it more rugged for spaceflight. The PSNDL navigation system also includes cameras and an inertial measurement unit to make it a complete navigation system capable of accurately determining a vehicle’s position and velocity for precision landing and other spaceflight applications. 
      NASA engineers and technicians install the Psionic Space Navigation Doppler Lidar (PSNDL) system into a testing pod on a NASA F/A-18 research aircraft ahead of February 2025 flight tests at NASA’s Armstrong Flight Research Center in Edwards, California.NASA The aircraft departed from NASA’s Armstrong Flight Research Center in Edwards, California, and conducted a variety of flight paths over several days in February 2025. It flew a large figure-8 loop and conducted several highly dynamic maneuvers over Death Valley, California, to collect navigation data at various altitudes, velocities, and orientations relevant for lunar and Mars entry and descent. Refurbished for these tests, the NASA F/A-18 pod can support critical data collection for other technologies and users at a low cost. 
      Doppler Lidar sensors provide a highly accurate measurement of speed by measuring the frequency shift between laser light emitted from the sensor reflected from the ground. Lidar are extremely useful in sunlight-challenged areas that may have long shadows and stark contrasts, such as the lunar South Pole. Pairing PSNDL with cameras adds the ability to visually compare pictures with surface reconnaissance maps of rocky terrain and navigate to landing at interesting locations on Mars. All the data is fed into a computer to make quick, real-time decisions to enable precise touchdowns at safe locations.

      On March 24, 1975, the last in a long line of super successful Saturn rockets rolled out from the vehicle assembly building to Launch Pad 39B at NASA’s Kennedy Space Center in Florida. The Saturn IB rocket for the Apollo-Soyuz Test Project was the 19th in the Saturn class stacked in the assembly building, beginning in 1966 with the Saturn V 500F facilities checkout vehicle. Thirteen flight Saturn V rockets followed, 12 to launch Apollo spacecraft and one to place the Skylab space station into orbit. In addition, workers stacked four flight Saturn IB rockets, three to launch crews to Skylab and one for Apollo-Soyuz, plus another for the Skylab rescue vehicle that was not needed and never launched. Previously, workers stacked Saturn I and Saturn IB rockets on the pads at Launch Complexes 34 and 37. With the successful liftoff in July 1975, the Saturn family of rockets racked up a 100 percent success rate of 32 launches. 

      Workers lower the Apollo command and service modules onto the spacecraft adaptor.NASA Technicians in the assembly building replace the fins on the Saturn IB rocket’s first stage. NASA Workers in the assembly building prepare to lower the spacecraft onto its Saturn IB rocket.NASA Inspections of the Saturn IB rocket’s first stage fins revealed hairline cracks in several hold-down fittings and managers ordered the replacement of all eight fins. While the cracks would not affect the flight of the rocket they bore the weight of the rocket on the mobile launcher. Workers finished the fin replacement on March 16. Engineers in Kennedy’s spacecraft operations building prepared the Apollo spacecraft for its historic space mission. By early March, they had completed checkout and assembly of the spacecraft and transported it to the assembly building on March 17 to mount it atop the Saturn IB’s second stage. Five days later, they topped off the rocket with the launch escape system. 

      The final Saturn IB begins its rollout from the vehicle assembly building. NASA The Saturn IB passes by the Launch Control Center. NASA Apollo astronauts Thomas Stafford, left, Vance Brand, and Donald “Deke” Slayton pose in front of their Saturn IB during the rollout.NASA On March 23, workers edged the mobile transporter carrying the Saturn IB just outside the assembly building’s High Bay 1, where engineers installed an 80-foot tall lightning mast atop the launch tower. The next morning, the stack continued its rollout to Launch Pad 39B with the prime crew of Thomas  Stafford, Vance Brand, and Donald “Deke” Slayton and support crew members Robert Crippen and Richard Truly on hand to observe. About 7,500 people, including guests, dependents of Kennedy employees and NASA Tours patrons, watched as the stack moved slowly out of the assembly building on its five-mile journey to the launch pad.
