Inside of the Electrostatics and Surface Physics Laboratory at NASA’s Kennedy Space Center in Florida, an electrodynamic dust shield (EDS) is in view on Jan. 18, 2023. The dust shield is one of the payloads that will fly aboard Firefly Aerospace’s Blue Ghost lunar lander as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative. NASA/Cory Huston Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the Moon or Mars, it is a significant hazard that must be mitigated. That’s why researchers at NASA’s Kennedy Space Center in Florida are seeking innovative ways to use the Electrodynamic Dust Shield (EDS) technology.
The EDS technology is headed to the Moon as part of the agency’s Artemis campaign. This innovative technology will be demonstrated on the lunar surface, where it will use electrical forces to lift and remove lunar regolith, or dirt, from various surfaces.
This dust-mitigating technology is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center in Florida Wednesday, Jan. 15, with Firefly Aerospace’s Blue Ghost Lander.
Using transparent electrodes and electric fields, EDS technology can lift and remove dust from a variety of surfaces for space applications ranging from thermal radiators, solar panels, and camera lenses to spacesuits, boots, and helmet visors. Controlling and removing the charged dust will be critical to the success of Moon missions under the agency’s CLPS initiative and Artemis campaign.
“For these CLPS and Artemis missions, dust exposure is a concern because the lunar surface is far different than what we’re used to here,” said Dr. Charles Buhler, lead research scientist at the Electrostatics and Surface Physics Laboratory at Kennedy. “Lunar regolith dust can get into gaskets and seals, into hatches, and even into habitats, which can pose a lot of issues for spacecraft and astronauts.”
Unlike dust particles on Earth, dust on the Moon’s surface is sharp and abrasive – like tiny shards of glass – because it hasn’t been exposed to weathering and elements like water and oxygen.
“Simply brushing lunar regolith across surfaces can make the problem worse because it’s also very electrostatically charged and highly insulating,” Buhler said.
Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. EDS was funded by the Space Technology Mission Directorate (STMD) Game Changing Development Program (GCD).

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Lunar Planet Vac, or LPV, is one of 10 payloads set to be carried to the Moon by the Blue Ghost 1 lunar lander in 2025. LPV is designed to efficiently collect and transfer lunar soil from the surface to other science and analysis instruments on the Moon.Photo courtesy Firefly Aerospace Among all the challenges of voyaging to and successfully landing on other worlds, the effective collection and study of soil and rock samples cannot be underestimated.
To quickly and thoroughly collect and analyze samples during next-generation Artemis Moon missions and future journeys to Mars and other planetary bodies, NASA seeks a paradigm shift in techniques that will more cost-effectively obtain samples, conduct in situ testing with or without astronaut oversight, and permit real-time sample data return to researchers on Earth.
That’s the planned task of an innovative technology demonstration called Lunar PlanetVac (LPV), one of 10 NASA payloads flying aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. LPV will be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.
Developed by Honeybee Robotics, a Blue Origin company of Altadena, California, LPV is a pneumatic, compressed gas-powered sample acquisition and delivery system – essentially, a vacuum cleaner that brings its own gas. It’s designed to efficiently collect and transfer lunar soil from the surface to other science instruments or sample return containers without reliance on gravity. Secured to the Blue Ghost lunar lander, LPV’s sampling head will use pressurized gas to stir up the lunar regolith, or soil, creating a small tornado. If successful, material from the dust cloud it creates then will be funneled into a transfer tube via the payload’s secondary pneumatic jets and collected in a sample container. The entire autonomous operation is expected to take just seconds and maintains planetary protection protocols. Collected regolith – including particles up to 1 cm in size, or roughly 0.4 inches – will be sieved and photographed inside the sample container with the findings transmitted back to Earth in real time.
The innovative approach to sample collection and in situ testing could prove to be a game-changer, said Dennis Harris, who manages the LPV payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
“There’s no digging, no mechanical arm to wear out requiring servicing or replacement – it functions like a vacuum cleaner,” Harris said. “The technology on this CLPS payload could benefit the search for water, helium, and other resources and provide a clearer picture of in situ materials available to NASA and its partners for fabricating lunar habitats and launch pads, expanding scientific knowledge and the practical exploration of the solar system every step of the way.”
Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA aims to be one of many customers on future flights. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the development of seven of the 10 CLPS payloads carried on Firefly’s Blue Ghost lunar lander.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Next Generation Lunar Retroreflector, or NGLR-1, is one of 10 payloads set to fly aboard the next delivery for NASA’s CLPS (Commercial Lunar Payload Services) initiative in 2025. NGLR-1, outfitted with a retroreflector, will be delivered to the lunar surface to reflect very short laser pulses from Earth-based lunar laser ranging observatories. Photo courtesy Firefly Aerospace Apollo astronauts set up mirror arrays, or “retroreflectors,” on the Moon to accurately reflect laser light beamed at them from Earth with minimal scattering or diffusion. Retroreflectors are mirrors that reflect the incoming light back in the same incoming direction. Calculating the time required for the beams to bounce back allowed scientists to precisely measure the Moon’s shape and distance from Earth, both of which are directly affected by Earth’s gravitational pull. More than 50 years later, on the cusp of NASA’s crewed Artemis missions to the Moon, lunar research still leverages data from those Apollo-era retroreflectors.
As NASA prepares for the science and discoveries of the agency’s Artemis campaign, state-of-the-art retroreflector technology is expected to significantly expand our knowledge about Earth’s sole natural satellite, its geological processes, the properties of the lunar crust and the structure of lunar interior, and how the Earth-Moon system is changing over time. This technology will also allow high-precision tests of Einstein’s theory of gravity, or general relativity.
That’s the anticipated objective of an innovative science instrument called NGLR (Next Generation Lunar Retroreflector), one of 10 NASA payloads set to fly aboard the next lunar delivery for the agency’s CLPS (Commercial Lunar Payload Services) initiative. NGLR-1 will be carried to the surface by Firefly Aerospace’s Blue Ghost 1 lunar lander.
Developed by researchers at the University of Maryland in College Park, NGLR-1 will be delivered to the lunar surface, located on the Blue Ghost lander, to reflect very short laser pulses from Earth-based lunar laser ranging observatories, which could greatly improve on Apollo-era results with sub-millimeter-precision range measurements. If successful, its findings will expand humanity’s understanding of the Moon’s inner structure and support new investigations of astrophysics, cosmology, and lunar physics – including shifts in the Moon’s liquid core as it orbits Earth, which may cause seismic activity on the lunar surface.
“NASA has more than half a century of experience with retroreflectors, but NGLR-1 promises to deliver findings an order of magnitude more accurate than Apollo-era reflectors,” said Dennis Harris, who manages the NGLR payload for the CLPS initiative at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
Deployment of the NGLR payload is just the first step, Harris noted. A second NGLR retroreflector, called the Artemis Lunar Laser Retroreflector (ALLR), is currently a candidate payload for flight on NASA’s Artemis III mission to the Moon and could be set up near the lunar south pole. A third is expected to be manifested on a future CLPS delivery to a non-polar location.
“Once all three retroreflectors are operating, they are expected to deliver unprecedented opportunities to learn more about the Moon and its relationship with Earth,” Harris said.

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 participated in several shows at venues in South Vietnam, Thailand, and Guam, kidding around with Hope and answering questions from the assembled service members. 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.

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.

On Dec. 22, the city of Fort Worth, Texas, honored native son Bean, with Conrad, Gordon, and their families joining him for the Alan Bean Day festivities. 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.

Apollo 13 astronauts Lovell, Haise, Young, and Duke participated in a geology training field trip between Dec. 17 and 20 on the Big Island of Hawaii. Geologist Patrick D. 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.

At the time tentatively planned for launch in July 1970, mission planners considered the Littrow area on the eastern edge of the Mare Serenitatis, characterized by dark material possibly of volcanic origin, as a potential landing site. 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.
