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.

      Landing on the Moon is not easy, particularly when a crew or spacecraft must meet exacting requirements. For Artemis missions to the lunar surface, those requirements include an ability to land within an area about as wide as a football field in any lighting condition amid tough terrain.

      NASA’s official lunar landing requirement is to be able to land within 50 meters (164 feet) of the targeted site and developing precision tools and technologies is critically important to mission success.

      NASA engineers recently took a major step toward safe and precise landings on the Moon – and eventually Mars and icy worlds – with a successful field test of hazard detection technology at NASA’s Kennedy Space Center Shuttle Landing Facility in Florida.

      A joint team from the Aeroscience and Flight Mechanics Division at NASA’s Johnson Space Center’s in Houston and Goddard Space Flight Center in Greenbelt, Maryland, achieved this huge milestone in tests  of the Goddard Hazard Detection Lidar from a helicopter at Kennedy in March 2025. 

      NASA’s Hazard Detection Lidar field test team at Kennedy Space Center’s Shuttle Landing Facility in Florida in March 2025. NASA The new lidar system is one of several sensors being developed as part of NASA’s Safe & Precise Landing – Integrated Capabilities Evolution (SPLICE) Program, a Johnson-managed cross-agency initiative under the Space Technology Mission Directorate to develop next-generation landing technologies for planetary exploration. SPLICE is an integrated descent and landing system composed of avionics, sensors, and algorithms that support specialized navigation, guidance, and image processing techniques. SPLICE is designed to enable landing in hard-to-reach and unknown areas that are of potentially high scientific interest.

      The lidar system, which can map an area equivalent to two football fields in just two seconds, is a crucial program component. In real time and compensating for lander motion, it processes 15 million short pulses of laser light to quickly scan surfaces and create real-time, 3D maps of landing sites to support precision landing and hazard avoidance. 

      Those maps will be read by the SPLICE Descent and Landing Computer, a high-performance multicore computer processor unit that analyzes all SPLICE sensor data and determines the spacecraft’s velocity, altitude, and terrain hazards. It also computes the hazards and determines a safe landing location. The computer was developed by the Avionics Systems Division at Johnson as a platform to test navigation, guidance, and flight software. It previously flew on Blue Origin’s New Shepard booster rocket.

      The NASA team prepares the Descent and Landing Computer for Hazard Detection Lidar field testing at Kennedy Space Center. NASA For the field test at Kennedy, Johnson led test operations and provided avionics and guidance, navigation, and control support. Engineers updated the computer’s firmware and software to support command and data interfacing with the lidar system. Team members from Johnson’s Flight Mechanics branch also designed a simplified motion compensation algorithm and NASA’s Jet Propulsion Laboratory in Southern California contributed a hazard detection algorithm, both of which were added to the lidar software by Goddard. Support from NASA contractors Draper Laboratories and Jacobs Engineering played key roles in the test’s success.

      Primary flight test objectives were achieved on the first day of testing, allowing the lidar team time to explore different settings and firmware updates to improve system performance. The data confirmed the sensor’s capability in a challenging, vibration-heavy environment, producing usable maps. Preliminary review of the recorded sensor data shows excellent reconstruction of the hazard field terrain.

      A Hazard Detection Lidar scan of a simulated hazard field at Kennedy Space Center (left) and a combined 3D map identifying roughness and slope hazards. NASA Beyond lunar applications, SPLICE technologies are being considered for use on Mars Sample Return, the Europa Lander, Commercial Lunar Payload Services flights, and Gateway. The DLC design is also being evaluated for potential avionics upgrades on Artemis systems.

      Additionally, SPLICE is supporting software tests for the Advancement of Geometric Methods for Active Terrain Relative Navigation (ATRN) Center Innovation Fund project, which is also part of Johnson’s Aeroscience and Flight Mechanics Division. The ATRN is working to develop algorithms and software that can use data from any active sensor – one measuring signals that were reflected, refracted, or scattered by a body’s surface or its atmosphere – to accurately map terrain and provide absolute and relative location information. With this type of system in place, spacecraft will not need external lighting sources to find landing sites.

      With additional suborbital flight tests planned through 2026, the SPLICE team is laying the groundwork for safer, more autonomous landings on the Moon, Mars, and beyond. As NASA prepares for its next era of exploration, SPLICE will be a key part of the agency’s evolving landing, guidance, and navigation capabilities.

      Intuitive Machines’ IM-2 captured an image March 6, 2025, after landing in a crater from the Moon’s South Pole. The lunar lander is on its side near the intended landing site, Mons Mouton. In the center of the image between the two lander legs is the Polar Resources Ice Mining Experiment 1 suite, which shows the drill deployed.Intuitive Machines NASA’s PRIME-1 (Polar Resources Ice Mining Experiment 1) mission was designed to demonstrate technologies to help scientists better understand lunar resources ahead of crewed Artemis missions to the Moon. During the short-lived mission on the Moon, the performance of PRIME-1’s technology gave NASA teams reason to celebrate.  
      “The PRIME-1 mission proved that our hardware works in the harshest environment we’ve ever tested it in,” said Janine Captain, PRIME-1 co-principal investigator and research chemist at NASA’s Kennedy Space Center in Florida. “While it may not have gone exactly to plan, this is a huge step forward as we prepare to send astronauts back to the Moon and build a sustainable future there.” 
      Intuitive Machines’ IM-2 mission launched to the Moon on Feb. 26, 2025, from NASA Kennedy’s Launch Complex 39A, as part of the company’s second Moon delivery for NASA under the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. The IM-2 Nova-C lunar lander, named Athena, carried PRIME-1 and its suite of two instruments: a drill known as TRIDENT (The Regolith and Ice Drill for Exploring New Terrain), designed to bring lunar soil to the surface; and a mass spectrometer, Mass Spectrometer Observing Lunar Operations (MSOLO), to study TRIDENT’s drill cuttings for the presence of gases that could one day help provide propellant or breathable oxygen to future Artemis explorers.  
      The IM-2 mission touched down on the lunar surface on March 6, just around 1,300 feet (400 meters) from its intended landing site of Mons Mouton, a lunar plateau near the Moon’s South Pole. The Athena lander was resting on its side inside a crater preventing it from recharging its solar cells, resulting in an end of the mission.
      “We were supposed to have 10 days of operation on the Moon, and what we got was closer to 10 hours,” said Julie Kleinhenz, NASA’s lead systems engineer for PRIME-1, as well as the in-situ resource utilization system capability lead deputy for the agency. “It was 10 hours more than most people get so I am thrilled to have been a part of it.” 
      Kleinhenz has spent nearly 20 years working on how to use lunar resources for sustained operations. In-situ resource utilization harnesses local natural resources at mission destinations. This enables fewer launches and resupply missions and significantly reduces the mass, cost, and risk of space exploration. With NASA poised to send humans back to the Moon and on to Mars, generating products for life support, propellants, construction, and energy from local materials will become increasingly important to future mission success.  
      “In-situ resource utilization is the key to unlocking long-term exploration, and PRIME-1 is helping us lay this foundation for future travelers.” Captain said.
      The PRIME-1 technology also set out to answer questions about the properties of lunar regolith, such as soil strength. This data could help inform the design of in-situ resource utilization systems that would use local resources to create everything from landing pads to rocket fuel during Artemis and later missions.  
      “Once we got to the lunar surface, TRIDENT and MSOLO both started right up, and performed perfectly. From a technology demonstrations standpoint, 100% of the instruments worked.” Kleinhenz said.
      The lightweight, low-power augering drill built by Honeybee Robotics, known as TRIDENT, is 1 meter long and features rotary and percussive actuators that convert energy into the force needed to drill. The drill was designed to stop at any depth as commanded from the ground and deposit its sample on the surface for analysis by MSOLO, a commercial off-the-shelf mass spectrometer modified by engineers and technicians at NASA Kennedy to withstand the harsh lunar environment. Designed to measure the composition of gases in the vicinity of the lunar lander, both from the lander and from the ambient exosphere, MSOLO can help NASA analyze the chemical makeup of the lunar soil and study water on the surface of the Moon.  
      Once on the Moon, the actuators on the drill performed as designed, completing multiple stages of movement necessary to drill into the lunar surface. Prompted by commands from technicians on Earth, the auger rotated, the drill extended to its full range, the percussion system performed a hammering motion, and the PRIME-1 team turned on an embedded core heater in the drill and used internal thermal sensors to monitor the temperature change.
      While MSOLO was able to perform several scans to detect gases, researchers believe from the initial data that the gases detected were all anthropogenic, or human in origin, such as gases vented from spacecraft propellants and traces of Earth water. Data from PRIME-1 accounted for some of the approximately 7.5 gigabytes of data collected during the IM-2 mission, and researchers will continue to analyze the data in the coming months and publish the results.

      The Mass Spectrometer Observing Lunar Operations (MSolo) for NASA’s Volatile Investigating Polar Exploration Rover (VIPER) mission is prepared for packing inside a laboratory in the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida on Feb. 21, 2023. MSolo is a commercial off-the-shelf mass spectrometer modified to work in space and it will help analyze the chemical makeup of landing sites on the Moon, as well as study water on the lunar surface.NASA/Kim Shiflett A NASA-developed technology that recently proved its capabilities in the harsh environment of space will soon head back to the Moon to search for gases trapped under the lunar surface thanks to a new Cooperative Research and Development Agreement between NASA and commercial company Magna Petra Corp.
      The Mass Spectrometer Observing Lunar Operations (MSOLO) successfully demonstrated the full range of its hardware in lunar conditions during the Intuitive Machines 2 mission earlier this year. Under the new agreement, a second MSOLO, mounted on a commercial rover, will launch to the Moon no earlier than 2026. Once on the lunar surface, it will measure low molecular weight volatiles in hopes of inferring the presence of rare isotopes, such as Helium-3, which is theorized to exist, trapped in the regolith, or lunar dust, of the Moon.
      “This new mission opportunity will help us determine what volatiles are present in the lunar surface, while also providing scientific insight for Magna Petra’s goals,” said Roberto Aguilar Ayala, research physicist at NASA’s Kennedy Space Center in Florida. “Learning more about the lunar volatiles and their isotopes supports NASA’s goal of sustaining long-term human space exploration. We will need to extract resources locally to enhance the capabilities of our astronauts to further exploration opportunities on the lunar surface.”
      The MSOLO instrument will be integrated on a commercial rover, selected by Magna Petra. The rover will allow MSOLO to gather the data needed for researchers to understand which low-molecular weight gases reside within the Moon’s surface.
      NASA will work with the partner to integrate MSOLO so that it will function properly with the rover, and the partner will analyze and share data in real time with NASA to understand the location of these volatiles on the Moon and their ability to be extracted in the future.
      Magna Petra hopes to understand the presence of Helium-3 isotope within the Moon’s surface, with the ultimate goal of collecting it and bringing it back to Earth for use in a variety of industries, including energy production through nuclear fusion, quantum computing, health care, and specialized laboratory equipment.
      The MSOLO instrument began as a commercial off-the-shelf mass spectrometer designed to analyze volatiles used in the manufacturing of semi-conductors, which helped keep NASA’s development costs down. NASA modified the device to withstand the rigors of spaceflight and the Moon’s harsh conditions. On its first journey to the Moon, MSOLO was part of the Polar Resources Ice Mining Experiment 1.
      Signed on April 2, the reimbursable agreement is the first of its kind established at NASA Kennedy. Under the agreement, Magna Petra will reimburse NASA for costs such as supporting MSOLO integration and testing with the rover, pre-mission preparation and mission operations of the instruments, and expertise in system engineering, avionics, and software.
      “This innovative agreement promises to provide valuable data to both partners,” said Jonathan Baker, chief of Spaceport Development at NASA Kennedy. “This approach demonstrates NASA’s commitment to finding unique ways to work with commercial industry to help advance technology in a fiscally responsible way and enabling innovation for the benefit of humankind.”
      Throughout the mission, NASA will retain ownership of MSOLO. Once the mission is complete, the instrument will no longer have access to power and communications and will remain on the surface of the Moon. The valuable data gathered during the mission will be submitted to the Planetary Data System for public dissemination.
