On Jan. 19, 1965, Gemini 2 successfully completed the second of two uncrewed test flights of the spacecraft and its Titan II booster, clearing the way for the first crewed mission. The 18-minute suborbital mission achieved the primary goals of flight qualifying the Gemini spacecraft, especially its heat shield during a stressful reentry. Recovery forces retrieved the capsule following its splashdown, allowing engineers to evaluate how its systems fared during the flight. The success of Gemini 2 enabled the first crewed mission to fly two months later, beginning a series of 10 flights over the following 20 months. The astronauts who flew these missions demonstrated the rendezvous and docking techniques necessary to implement the Lunar Orbit Rendezvous method NASA chose for the Moon landing mission. They also proved that astronauts could work outside their spacecraft during spacewalks and that spacecraft and astronauts could function for at least eight days, the minimum time for a roundtrip lunar mission. The Gemini program proved critical to fulfill President John F. Kennedy’s goal of landing a man on the Moon and returning him safely to Earth before the end of the 1960s.

Following the success of Gemini 1 in April 1964, NASA had hoped to fly the second mission before the end of the year and the first crewed mission by January 1965. The two stages of the Titan II rocket arrived at Cape Kennedy from the Martin Marietta factory in Baltimore on July 11, and workers erected it on Launch Pad 19 five days later. A lightning strike at the pad on Aug. 17 invalidated all previous testing and required replacement of some pad equipment. A series of three hurricanes in August and September forced workers to partially or totally unstack the vehicle before stacking it for the final time on Sept. 14. The Gemini 2 spacecraft arrived at Cape Kennedy from its builder, the McDonnell Company in St. Louis, on Sept. 21, and workers hoisted it to the top of the Titan II on Oct. 18. Technical issues delayed the spacecraft’s physical mating to the rocket until Nov. 5. These accumulated delays pushed the launch date back to Dec. 9.

Fueling of the rocket began late on Dec. 8, and following three brief holds in the countdown, the Titan’s two first stage engines ignited at 11:41 a.m. EST on Dec. 9. and promptly shut down one second later. Engineers later determined that a cracked valve resulted in loss of hydraulic pressure, causing the malfunction detection system to switch to its backup mode, forcing a shutdown of the engines. Repairs meant a delay into the new year. On Jan. 19, 1965, following a mostly smooth countdown, Gemini 2 lifted off from Pad 19 at 9:04 a.m. EST.
The Mission Control Center (MCC) at NASA’s Kennedy Space Center in Florida. In the MCC, astronauts Eugene Cernan, left, Walter Schirra, Gordon Cooper, Donald “Deke” Slayton, and Virgil “Gus” Grissom monitor the Gemini 2 flight. In the Gemini Mission Control Center at NASA’s Kennedy Space Center in Florida, Flight Director Christopher C. Kraft led a team of flight controllers that monitored all aspects of the flight. At the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston, a team of controllers led by Flight Director John Hodge passively monitored the flight from the newly built Mission Control Center. They would act as observers for this flight and Gemini 3, the first crewed mission, before taking over full control with Gemini IV, and control all subsequent American human spaceflights. The Titan rocket’s two stages placed Gemini 2 into a suborbital trajectory, reaching a maximum altitude of 98.9 miles, with the vehicle attaining a maximum velocity of 16,709 miles per hour. Within a minute after separating from the Titan’s second stage, Gemini 2 executed a maneuver to orient its heat shield in the direction of flight to prepare for reentry. Flight simulators installed where the astronauts normally would sit controlled the maneuvers. About seven minutes after liftoff, Gemini 2 jettisoned its equipment section, followed by firing of the retrorockets, and then separation of the retrorocket section, exposing the spacecraft’s heat shield.

Gemini 2 then began its reentry, the heat shield protecting the spacecraft from the 2,000-degree heat generated by friction with the Earth’s upper atmosphere. A pilot parachute pulled away the rendezvous and recovery section. At 10,000 feet, the main parachute deployed, and Gemini 2 descended to a splashdown 2,127 miles from its launch pad, after a flight of 18 minutes 16 seconds. The splashdown took place in the Atlantic Ocean about 800 miles east of San Juan, Puerto Rico, and 25 miles from the prime recovery ship, the U.S.S. Lake Champlain (CVS-39).
A U.S. Navy helicopter hovers over the Gemini 2 capsule following its splashdown as a diver jumps into the water. Sailors hoist Gemini 2 aboard the U.S.S. Lake Champlain. U.S. Navy helicopters delivered divers to the splashdown area, who installed a flotation collar around the spacecraft. The Lake Champlain pulled alongside, and sailors hoisted the capsule onto the carrier, securing it on deck one hour forty minutes after liftoff. The spacecraft appeared to be in good condition and arrived back at Cape Kennedy on Jan. 22 for a thorough inspection. As an added bonus, sailors recovered the rendezvous and recovery section. Astronaut Virgil “Gus” Grissom, whom along with John Young NASA had selected to fly the first crewed Gemini mission, said after the splashdown, “We now see the road clear to our flight, and we’re looking forward to it.” Flight Director Kraft called it “very successful.” Gemini Program Manager Charles Matthews predicted the first crewed mission could occur within three months. Gemini 3 actually launched on March 23.

Former MOL and NASA astronaut Robert Crippen stands beside the only flown Gemini-B capsule – note the hatch in the heat shield at top. Gemini 2 not only cleared the way for the first crewed Gemini mission and the rest of the program, it also took on a second life as a test vehicle for the U.S. Air Force’s Manned Orbiting Laboratory (MOL). The Air Force modified the spacecraft, including cutting a hatch through its heat shield, renamed it Gemini-B, and launched it on Nov. 3, 1966, atop a Titan IIIC rocket. The test flight successfully demonstrated the hatch in the heat shield design during the capsule’s reentry after a 33-minute suborbital flight. Recovery forces retrieved the Gemini-B capsule in the South Atlantic Ocean and returned it to the Air Force for postflight inspection. This marked the only repeat flight of an American spacecraft intended for human spaceflight until the advent of the space shuttle. Visitors can view Gemini 2/Gemini-B on display at the Cape Canaveral Space Force Museum.

Insights into metal alloy solidification
Researchers report details of phase and structure in the solidification of metal alloys on the International Space Station, including formation of microstructures. Because these microstructures determine a material’s mechanical properties, this work could support improvements in techniques for producing coatings and additive manufacturing or 3D printing processes.
METCOMP, an ESA (European Space Agency) investigation, studied solidification in microgravity using transparent organic mixtures as stand-ins for metal alloys. Conducting the research in microgravity removed the influence of convection and other effects of gravity. Results help scientists better understand and validate models of solidification mechanisms, enabling better forecasting of microstructures and improving manufacturing processes.

Researchers determined the height of a blue discharge from a thundercloud using ground-based electric field measurements and space-based optical measurements from Atmosphere-Space Interactions Monitor (ASIM). This finding helps scientists better understand how these high-altitude lightning-related events affect atmospheric chemistry and could help improve atmospheric models and climate and weather predictions.
ESA’s ASIM is an Earth observation facility that studies severe thunderstorms and upper-atmospheric lighting events and their role in the Earth’s atmosphere and climate. Upper-atmospheric lightning, also known as transient luminous events, occurs well above the altitudes of normal lightning and storm clouds. The data collected by ASIM could support research on the statistical properties of many upper atmosphere lightning events, such as comparison of peak intensities of blue and red pulses with reports from lightning detection networks.

Scientists report that they can use modeling of neutron star PSRJ1231−1411’s X-ray pulses to infer its mass and radius and narrow the possible behaviors of the dense matter at its core. This finding provides a better understanding of the composition and structure of these celestial objects, improving models that help answer questions about conditions in the universe.
The Neutron star Interior Composition Explorer provides high-precision measurements of pulses of X-ray radiation from neutron stars. This particular neutron star presented challenges in finding a fit between models and data, possibly due to fundamental issues with its pulse profile. The authors recommend a program of simulations using synthetic data to determine whether there are fundamental issues with this type of pulse profile that could prevent efforts to obtain tighter and more robust constraints.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A test rover with shape memory alloy spring tires traverses rocky, Martian-simulated terrain.Credit: NASA The mystique of Mars has been studied for centuries. The fourth planet from the Sun is reminiscent of a rich, red desert and features a rugged surface challenging to traverse. While several robotic missions have landed on Mars, NASA has only explored 1% of its surface. Ahead of future human and robotic missions to the Red Planet, NASA recently completed rigorous rover testing on Martian-simulated terrain, featuring revolutionary shape memory alloy spring tire technology developed at the agency’s Glenn Research Center in Cleveland in partnership with Goodyear Tire & Rubber.
Rovers — mobile robots that explore lunar or planetary surfaces — must be equipped with adequate tires for the environments they’re exploring. As Mars has an uneven, rocky surface, durable tires are essential for mobility. Shape memory alloy (SMA) spring tires help make that possible.
Shape memory alloys are metals that can return to their original shape after being bent, stretched, heated, and cooled. NASA has used them for decades, but applying this technology to tires is a fairly new concept.
“We at Glenn are one of the world leaders in bringing the science and understanding of how you change the alloy compositions, how you change the processing of the material, and how you model these systems in a way that we can control and stabilize the behaviors so that they can actually be utilized in real applications,” said Dr. Santo Padula II, materials research engineer at NASA Glenn.
Researchers from NASA’s Glenn Research Center and Airbus Defence & Space pose with a test rover on Martian-simulated terrain.Credit: NASA Padula and his team have tested several applications for SMAs, but his epiphany of the possibilities for tires came about because of a chance encounter.
While leaving a meeting, Padula encountered Colin Creager, a mechanical engineer at NASA Glenn whom he hadn’t seen in years. Creager used the opportunity to tell him about the work he was doing in the NASA Glenn Simulated Lunar Operations (SLOPE) Laboratory, which can simulate the surfaces of the Moon and Mars to help scientists test rover performance. He brought Padula to the lab, where Padula immediately took note of the spring tires. At the time, they were made of steel.
Padula remarked, “The minute I saw the tire, I said, aren’t you having problems with those plasticizing?” Plasticizing refers to a metal undergoing deformation that isn’t reversible and can lead to damage or failure of the component.
“Colin told me, ‘That’s the only problem we can’t solve.’” Padula continued, “I said, I have your solution. I’m developing a new alloy that will solve that. And that’s how SMA tires started.”
From there, Padula, Creager, and their teams joined forces to improve NASA’s existing spring tires with a game-changing material: nickel-titanium SMAs. The metal can accommodate deformation despite extreme stress, permitting the tires to return to their original shape even with rigorous impact, which is not possible for spring tires made with conventional metal.
Credit: NASA Since then, research has been abundant, and in the fall of 2024, teams from NASA Glenn traveled to Airbus Defence and Space in Stevenage, United Kingdom, to test NASA’s innovative SMA spring tires. Testing took place at the Airbus Mars Yard — an enclosed facility created to simulate the harsh conditions of Martian terrain.
“We went out there with the team, we brought our motion tracking system and did different tests uphill and back downhill,” Creager said. “We conducted a lot of cross slope tests over rocks and sand where the focus was on understanding stability because this was something we had never tested before.”
During the tests, researchers monitored rovers as the wheels went over rocks, paying close attention to how much the crowns of the tires shifted, any damage, and downhill sliding. The team expected sliding and shifting, but it was very minimal, and testing met all expectations. Researchers also gathered insights about the tires’ stability, maneuverability, and rock traversal capabilities.
As NASA continues to advance systems for deep space exploration, the agency’s Extravehicular Activity and Human Surface Mobility program enlisted Padula to research additional ways to improve the properties of SMAs for future rover tires and other potential uses, including lunar environments.
“My goal is to extend the operating temperature capability of SMAs for applications like tires, and to look at applying these materials for habitat protection,” Padula said. “We need new materials for extreme environments that can provide energy absorption for micrometeorite strikes that happen on the Moon to enable things like habitat structures for large numbers of astronauts and scientists to do work on the Moon and Mars.”
Researchers say shape memory alloy spring tires are just the beginning.

Creating a golden streak in the night sky, a SpaceX Falcon 9 rocket carrying Firefly Aerospace’s Blue Ghost Mission One lander soars upward after liftoff from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Wednesday, Jan. 15, as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative. The Blue Ghost lander will carry 10 NASA science and technology instruments to the lunar surface to further understand the Moon and help prepare for future human missions.Credit: NASA/Frank Michaux A suite of NASA scientific investigations and technology demonstrations is on its way to our nearest celestial neighbor aboard a commercial spacecraft, where they will provide insights into the Moon’s environment and test technologies to support future astronauts landing safely on the lunar surface under the agency’s Artemis campaign.
Carrying science and tech on Firefly Aerospace’s first CLPS or Commercial Lunar Payload Services flight for NASA, Blue Ghost Mission 1 launched at 1:11 a.m. EST aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. The company is targeting a lunar landing on Sunday, March 2.
“This mission embodies the bold spirit of NASA’s Artemis campaign – a campaign driven by scientific exploration and discovery,” said NASA Deputy Administrator Pam Melroy. “Each flight we’re part of is vital step in the larger blueprint to establish a responsible, sustained human presence at the Moon, Mars, and beyond. Each scientific instrument and technology demonstration brings us closer to realizing our vision. Congratulations to the NASA, Firefly, and SpaceX teams on this successful launch.”
Once on the Moon, NASA will test and demonstrate lunar drilling technology, regolith (lunar rocks and soil) sample collection capabilities, global navigation satellite system abilities, radiation tolerant computing, and lunar dust mitigation methods. The data captured could also benefit humans on Earth by providing insights into how space weather and other cosmic forces impact our home planet.
“NASA leads the world in space exploration, and American companies are a critical part of bringing humanity back to the Moon,” said Nicola Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “We learned many lessons during the Apollo Era which informed the technological and science demonstrations aboard Firefly’s Blue Ghost Mission 1 – ensuring the safety and health of our future science instruments, spacecraft, and, most importantly, our astronauts on the lunar surface. I am excited to see the incredible science and technological data Firefly’s Blue Ghost Mission 1 will deliver in the days to come.”
As part of NASA’s modern lunar exploration activities, CLPS deliveries to the Moon will help humanity better understand planetary processes and evolution, search for water and other resources, and support long-term, sustainable human exploration of the Moon in preparation for the first human mission to Mars.
There are 10 NASA payloads flying on this flight:
Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER) will characterize heat flow from the interior of the Moon by measuring the thermal gradient and conductivity of the lunar subsurface. It will take several measurements to about a 10-foot final depth using pneumatic drilling technology with a custom heat flow needle instrument at its tip. Lead organization: Texas Tech University Lunar PlanetVac (LPV) is designed to collect regolith samples from the lunar surface using a burst of compressed gas to drive the regolith into a sample chamber for collection and analysis by various instruments. Additional instrumentation will then transmit the results back to Earth. Lead organization: Honeybee Robotics Next Generation Lunar Retroreflector (NGLR) serves as a target for lasers on Earth to precisely measure the distance between Earth and the Moon. The retroreflector that will fly on this mission could also collect data to understand various aspects of the lunar interior and address fundamental physics questions. Lead organization: University of Maryland Regolith Adherence Characterization (RAC) will determine how lunar regolith sticks to a range of materials exposed to the Moon’s environment throughout the lunar day. The RAC instrument will measure accumulation rates of lunar regolith on the surfaces of several materials including solar cells, optical systems, coatings, and sensors through imaging to determine their ability to repel or shed lunar dust. The data captured will allow the industry to test, improve, and protect spacecraft, spacesuits, and habitats from abrasive regolith. Lead organization: Aegis Aerospace Radiation Tolerant Computer (RadPC) will demonstrate a computer that can recover from faults caused by ionizing radiation. Several RadPC prototypes have been tested aboard the International Space Station and Earth-orbiting satellites, but now will demonstrate the computer’s ability to withstand space radiation as it passes through Earth’s radiation belts, while in transit to the Moon, and on the lunar surface. Lead organization: Montana State University Electrodynamic Dust Shield (EDS) is an active dust mitigation technology that uses electric fields to move and prevent hazardous lunar dust accumulation on surfaces. The EDS technology is designed to lift, transport, and remove particles from surfaces with no moving parts. Multiple tests will demonstrate the feasibility of the self-cleaning glasses and thermal radiator surfaces on the Moon. In the event the surfaces do not receive dust during landing, EDS has the capability to re-dust itself using the same technology. Lead organization: NASA’s Kennedy Space Center Lunar Environment heliospheric X-ray Imager (LEXI) will capture a series of X-ray images to study the interaction of solar wind and the Earth’s magnetic field that drives geomagnetic disturbances and storms. Deployed and operated on the lunar surface, this instrument will provide the first global images showing the edge of Earth’s magnetic field for critical insights into how space weather and other cosmic forces surrounding our planet impact it. Lead organizations: NASA’s Goddard Space Flight Center, Boston University, and Johns Hopkins University Lunar Magnetotelluric Sounder (LMS) will characterize the structure and composition of the Moon’s mantle by measuring electric and magnetic fields. This investigation will help determine the Moon’s temperature structure and thermal evolution to understand how the Moon has cooled and chemically differentiated since it formed. Lead organization: Southwest Research Institute Lunar GNSS Receiver Experiment (LuGRE) will demonstrate the possibility of acquiring and tracking signals from Global Navigation Satellite System constellations, specifically GPS and Galileo, during transit to the Moon, during lunar orbit, and on the lunar surface. If successful, LuGRE will be the first pathfinder for future lunar spacecraft to use existing Earth-based navigation constellations to autonomously and accurately estimate their position, velocity, and time. Lead organizations: NASA Goddard, Italian Space Agency Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) will use stereo imaging photogrammetry to capture the impact of rocket plume on lunar regolith as the lander descends on the Moon’s surface. The high-resolution stereo images will aid in creating models to predict lunar regolith erosion, which is an important task as bigger, heavier payloads are delivered to the Moon in close proximity to each other. This instrument also flew on Intuitive Machine’s first CLPS delivery. Lead organization: NASA’s Langley Research Center “With 10 NASA science and technology instruments launching to the Moon, this is the largest CLPS delivery to date, and we are proud of the teams that have gotten us to this point,” said Chris Culbert, program manager for the Commercial Lunar Payload Services initiative at NASA’s Johnson Space Center in Houston. “We will follow this latest CLPS delivery with more in 2025 and later years. American innovation and interest to the Moon continues to grow, and NASA has already awarded 11 CLPS deliveries and plans to continue to select two more flights per year.”
Firefly’s Blue Ghost lander is targeted to land near a volcanic feature called Mons Latreille within Mare Crisium, a more than 300-mile-wide basin located in the northeast quadrant of the Moon’s near side. The NASA science on this flight will gather valuable scientific data studying Earth’s nearest neighbor and helping pave the way for the first Artemis astronauts to explore the lunar surface later this decade.

Firefly Aerospace’s Blue Ghost lander getting encapsulated in SpaceX’s rocket fairing ahead of the planned liftoff for 1:11 a.m. EST Jan. 15 from Launch Complex 39A at NASA’s Kennedy Space Center in FloridaSpaceX As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, the agency is preparing to fly ten instruments aboard Firefly Aerospace’s first delivery to the Moon. These science payloads and technology demonstrations will help advance our understanding of the Moon and planetary processes, while paving the way for future crewed missions on the Moon and beyond, for the benefit of all.
Firefly’s lunar lander, named Blue Ghost, is scheduled to launch on a SpaceX Falcon 9 rocket Wednesday, Jan.15, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. After a 45-day cruise phase, Blue Ghost is targeted to land near a volcanic feature called Mons Latreille within Mare Crisium, a basin approximately 340 miles wide (550 kilometers) located in the northeast quadrant of the Moon’s near side.
How can we enable more precise navigation on the Moon? How do spacecraft interact with the lunar surface? How does Earth’s magnetic field influence the effects of space weather on our home planet? NASA’s instruments on this flight will conduct first-of-their-kind demonstrations to help answer these questions and more, including testing regolith sampling technologies, lunar subsurface drilling capabilities, increasing precision of positioning and navigation abilities, testing radiation tolerant computing, and learning how to mitigate lunar dust during lunar landings.
The ten NASA payloads aboard Firefly’s Blue Ghost lander include:
Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER) will measure heat flow from the Moon’s interior by measuring the thermal gradient, or changes in temperature at various depths, and thermal conductivity, or the subsurface material’s ability to let heat pass through it. LISTER will take several measurements up to 10 feet deep using pneumatic drilling technology with a custom heat flow needle instrument at its tip. Data from LISTER will help scientists retrace the Moon’s thermal history and understand how it formed and cooled. Lead organization: Texas Tech University
Lunar PlanetVac (LPV) is designed to collect regolith samples from the lunar surface using a burst of compressed gas to drive the regolith into a sample chamber (sieving) for collection and analysis by various instruments. Additional instrumentation will then transmit the results back to Earth. The LPV payload is designed to help increase the science return from planetary missions by testing low-cost technologies for collecting regolith samples in-situ. Lead organization: Honeybee Robotics
Next Generation Lunar Retroreflector (NGLR) serves as a target for lasers on Earth to precisely measure the distance between Earth and the Moon by reflecting very short laser pulses from Earth-based Lunar Laser Ranging Observatories. The laser pulse transit time to the Moon and back is used to determine the distance. Data from NGLR could improve the accuracy of our lunar coordinate system and contribute to our understanding of the inner structure of the Moon and fundamental physics questions. Lead organization: University of Maryland
Regolith Adherence Characterization (RAC) will determine how lunar regolith sticks to a range of materials exposed to the Moon’s environment throughout the lunar day. RAC will measure accumulation rates of lunar regolith on surfaces (for example, solar cells, optical systems, coatings, and sensors) through imaging to determine their ability to repel or shed lunar dust. The data captured will help test, improve, and protect spacecraft, spacesuits, and habitats from abrasive regolith. Lead organization: Aegis Aerospace
Radiation Tolerant Computer (RadPC) will demonstrate a computer that can recover from faults caused by ionizing radiation. Several RadPC prototypes have been tested aboard the International Space Station and Earth-orbiting satellites, but this flight will provide the biggest trial yet by demonstrating the computer’s ability to withstand space radiation as it passes through Earth’s radiation belts, while in transit to the Moon, and on the lunar surface. Lead organization: Montana State University
Electrodynamic Dust Shield (EDS) is an active dust mitigation technology that uses electric fields to move and prevent hazardous lunar dust accumulation on surfaces. EDS is designed to lift, transport, and remove particles from surfaces with no moving parts. Multiple tests will demonstrate the feasibility of the self-cleaning glasses and thermal radiator surfaces on the Moon.

Deployed and operated on the lunar surface, this instrument will provide the first global images showing the edge of Earth’s magnetic field for critical insights into how space weather and other cosmic forces surrounding our planet impact Earth. Lead organizations: Boston University, NASA’s Goddard Space Flight Center, and Johns Hopkins University
Lunar Magnetotelluric Sounder (LMS) will characterize the structure and composition of the Moon’s mantle by measuring electric and magnetic fields. This investigation will help determine the Moon’s temperature structure and thermal evolution to understand how the Moon has cooled and chemically differentiated since it formed. Lead organization: Southwest Research Institute

If successful, LuGRE will be the first pathfinder for future lunar spacecraft to use existing Earth-based navigation constellations to autonomously and accurately estimate their position, velocity, and time. Lead organizations: NASA Goddard, Italian Space Agency
Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) will use stereo imaging photogrammetry to capture the impact of the rocket exhaust plume on lunar regolith as the lander descends on the Moon’s surface. The high-resolution stereo images will aid in creating models to predict lunar regolith erosion, which is an important task as bigger, heavier spacecraft and hardware are delivered to the Moon in close proximity to each other. This instrument also flew on Intuitive Machines’ first CLPS delivery. Lead organization: NASA’s Langley Research Center
Through the CLPS initiative, NASA purchases lunar landing and surface operations services from American companies. The agency uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon. By supporting a robust cadence of lunar deliveries, NASA will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry.
