This artist’s concept of Blue Ghost Mission 4 shows Firefly’s Blue Ghost lunar lander and NASA payloads in the lunar South Pole Region, through NASA’s CLPS (Commercial Lunar Payload Services) initiative.Credit: Firefly Aerospace NASA has awarded Firefly Aerospace of Cedar Park, Texas, $176.7 million to deliver two rovers and three scientific instruments to the lunar surface as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign to explore more of the Moon than ever before.
This delivery is the first time NASA will use multiple rovers and a variety of stationary instruments, in a collaborative effort with the CSA (Canadian Space Agency) and the University of Bern, to help us understand the chemical composition of the lunar South Pole region and discover the potential for using resources available in permanently shadowed regions of the Moon.
“Through CLPS, NASA is embracing a new era of lunar exploration, with commercial companies leading the way,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “These investigations will produce critical knowledge required for long-term sustainability and contribute to a deeper understanding of the lunar surface, allowing us to meet our scientific and exploration goals for the South Pole region of the Moon for the benefit of all.”
Under the new CLPS task order, Firefly is tasked with delivering end-to-end payload services to the lunar surface, with a period of performance from Tuesday to March 29, 2030. The company’s lunar lander is targeted to land at the Moon’s South Pole region in 2029.
This is Firefly’s fifth task order award and fourth lunar mission through CLPS. Firefly’s first delivery successfully landed on the Moon’s near side in March 2025 with 10 NASA payloads. The company’s second mission, targeting a launch in 2026, includes a lunar orbit drop-off of a satellite combined with a delivery to the lunar surface on the far side. Firefly’s third lunar mission will target landing in the Gruithuisen Domes on the near side of the Moon in 2028, delivering six experiments to study that enigmatic lunar volcanic terrain.
“As NASA sends both humans and robots to further explore the Moon, CLPS deliveries to the lunar South Pole region will provide a better understanding of the exploration environment, accelerating progress toward establishing a long-term human presence on the Moon, as well as eventual human missions to Mars,” said Adam Schlesinger, manager of the CLPS initiative at NASA’s Johnson Space Center in Houston.
The rovers and instruments that are part of this newly awarded flight include:
MoonRanger is an autonomous microrover that will explore the lunar surface. MoonRanger will collect images and telemetry data while demonstrating autonomous capabilities for lunar polar exploration. Its onboard Neutron Spectrometer System instrument will study hydrogen-bearing volatiles and the composition of lunar regolith, or soil.
Lead development organizations: NASA’s Ames Research Center in California’s Silicon Valley, and Carnegie Mellon University and Astrobotic, both in Pittsburgh. Stereo Cameras for Lunar Plume Surface Studies will use enhanced stereo imaging photogrammetry, active illumination, and ejecta impact detection sensors 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 help predict lunar regolith erosion and ejecta characteristics, as bigger, heavier spacecraft and hardware are delivered to the Moon near each other in the future.
Lead development organization: NASA’s Langley Research Center in Hampton, Virginia. Laser Retroreflector Array is an array of eight retroreflectors on an aluminum support structure that enables precision laser ranging, a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The array is a passive optical instrument, which functions without power, and will serve as a permanent location marker on the Moon for decades to come.
Lead development organization: NASA’s Goddard Space Flight Center in Greenbelt, Maryland. A CSA Rover is designed to access and explore remote South Pole areas of interest, including permanently shadowed regions, and to survive at least one lunar night. The CSA rover has stereo cameras, a neutron spectrometer, two imagers (visible to near-infrared), a radiation micro-dosimeter, and a NASA-contributed thermal imaging radiometer developed by the Applied Physics Laboratory. These instruments will advance our understanding of the physical and chemical properties of the lunar surface, the geological history of the Moon, and potential resources such as water ice. It will also improve our understanding of the environmental challenges that await future astronauts and their life support systems.
Lead development organization: CSA. Laser Ionization Mass Spectrometer is a mass spectrometer that will analyze the element and isotope composition of lunar regolith. The instrument will utilize a Firefly-built robotic arm and Titanium shovel that will deploy to the lunar surface and support regolith excavation. The system will then funnel the sample into its collection unit and use a pulsed laser beam to identify differences in chemistry compared to samples studied in the past, like those collected during the Apollo program. Grain-by-grain analyses will provide a better understanding of the chemical complexity of the landing site and the surrounding area, offering insights into the evolution of the Moon.
Lead development organization: University of Bern in Switzerland. 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, and to support human exploration beyond to Mars. 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.

Jackson NASA Headquarters building in Washington. Senegal is the 56th country to sign the Artemis Accords, which establish a practical set of principles to guide space exploration cooperation among nations participating in NASA’s Artemis program.Credit: NASA/Keegan Barber Senegal signed the Artemis Accords Thursday during a ceremony hosted by NASA at the agency’s headquarters in Washington, becoming the latest nation to commit to the responsible exploration of space for all humanity.
“Following a meeting between Senegal President Faye and President Trump, today, NASA built upon the strong relations between our two nations as the Senegalese Agency for Space Studies signed the Artemis Accords,” said acting NASA Administrator Sean Duffy. “With Senegal as the 56th signatory, I am proud to further President Trump’s strong legacy of global cooperation in space.”
Director General of the Senegalese space agency (ASES) Maram Kairé signed the Artemis Accords on behalf of Senegal. Jonathan Pratt, senior bureau official for African Affairs at the U.S. Department of State, and Abdoul Wahab Haidara, ambassador of Senegal to the United States, also participated in the event.
“Senegal’s adherence to the Artemis Accords reflects our commitment to a multilateral, responsible, and transparent approach to space,” said Kairé. “This signature marks a meaningful step in our space diplomacy and in our ambition to contribute to the peaceful exploration of outer space.”
The Artemis Accords signing ceremony took place two weeks after President Trump’s meeting in Washington with Senegal’s President Bassirou Diomaye Faye and other countries of Africa focused on U.S.-Africa engagement.
Astronomers from Senegal have supported NASA missions by participating in multiple observations when asteroids or planets pass in front of stars, casting shadows on Earth. In 2021, NASA also collaborated with Kairé and a group of astronomers for a ground observation campaign in Senegal. As the asteroid Orus passed in front of a star, they positioned telescopes along the path of the asteroid’s shadow to estimate its shape and size. NASA’s Lucy spacecraft will approach Orus in 2028, as part of its mission to explore Jupiter’s Trojan asteroids.
In 2020, during the first Trump Administration, the United States, led by NASA and the U.S. Department of State, joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies.
The accords introduced the first set of practical principles aimed at enhancing the safety, transparency, and coordination of civil space exploration on the Moon, Mars, and beyond.
Signing the Artemis Accords means to explore peaceably and transparently, to render aid to those in need, to ensure unrestricted access to scientific data that all of humanity can learn from, to ensure activities do not interfere with those of others, to preserve historically significant sites and artifacts, and to develop best practices for how to conduct space exploration activities for the benefit of all.
More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful, and prosperous future in space.

An artist’s concept design of NASA’s Lunar Terrain Vehicle.Credit: NASA NASA has selected three instruments to travel to the Moon, with two planned for integration onto an LTV (Lunar Terrain Vehicle) and one for a future orbital opportunity.
The LTV is part of NASA’s efforts to explore the lunar surface as part of the Artemis campaign and is the first crew-driven vehicle to operate on the Moon in more than 50 years. Designed to hold up to two astronauts, as well as operate remotely without a crew, this surface vehicle will enable NASA to achieve more of its science and exploration goals over a wide swath of lunar terrain.
“The Artemis Lunar Terrain Vehicle will transport humanity farther than ever before across the lunar frontier on an epic journey of scientific exploration and discovery,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “By combining the best of human and robotic exploration, the science instruments selected for the LTV will make discoveries that inform us about Earth’s nearest neighbor as well as benefit the health and safety of our astronauts and spacecraft on the Moon.”
The Artemis Infrared Reflectance and Emission Spectrometer (AIRES) will identify, quantify, and map lunar minerals and volatiles, which are materials that evaporate easily, like water, ammonia, or carbon dioxide. The instrument will capture spectral data overlaid on visible light images of both specific features of interest and broad panoramas to discover the distribution of minerals and volatiles across the Moon’s south polar region. The AIRES instrument team is led by Phil Christensen from Arizona State University in Tempe.
The Lunar Microwave Active-Passive Spectrometer (L-MAPS) will help define what is below the Moon’s surface and search for possible locations of ice. Containing both a spectrometer and a ground-penetrating radar, the instrument suite will measure temperature, density, and subsurface structures to more than 131 feet (40 meters) below the surface. The L-MAPS instrument team is led by Matthew Siegler from the University of Hawaii at Manoa.
When combined, the data from the two instruments will paint a picture of the components of the lunar surface and subsurface to support human exploration and will uncover clues to the history of rocky worlds in our solar system. The instruments also will help scientists characterize the Moon’s resources, including what the Moon is made of, potential locations of ice, and how the Moon changes over time.
In addition to the instruments selected for integration onto the LTV, NASA also selected the Ultra-Compact Imaging Spectrometer for the Moon (UCIS-Moon) for a future orbital flight opportunity. The instrument will provide regional context to the discoveries made from the LTV. From above, UCIS-Moon will map the Moon’s geology and volatiles and measure how human activity affects those volatiles. The spectrometer also will help identify scientifically valuable areas for astronauts to collect lunar samples, while its wide-view images provide the overall context for where these samples will be collected. The UCIS-Moon instrument will provide the Moon’s highest spatial resolution data of surface lunar water, mineral makeup, and thermophysical properties. The UCIS-Moon instrument team is led by Abigail Fraeman from NASA’s Jet Propulsion Laboratory in Southern California.
“Together, these three scientific instruments will make significant progress in answering key questions about what minerals and volatiles are present on and under the surface of the Moon,” said Joel Kearns, deputy associate administrator for Exploration, Science Mission Directorate at NASA Headquarters. “With these instruments riding on the LTV and in orbit, we will be able to characterize the surface not only where astronauts explore, but also across the south polar region of the Moon, offering exciting opportunities for scientific discovery and exploration for years to come.”
Leading up to these instrument selections, NASA has worked with all three lunar terrain vehicle vendors – Intuitive Machines, Lunar Outpost, and Venturi Astrolab – to complete their preliminary design reviews. This review demonstrates that the initial design of each commercial lunar rover meets all of NASA’s system requirements and shows that the correct design options have been selected, interfaces have been identified, and verification methods have been described. NASA will evaluate the task order proposals received from each LTV vendor and make a selection decision on the demonstration mission by the end of 2025.
Through Artemis, NASA will address high priority science questions, focusing on those that are best accomplished by on-site human explorers on and around the Moon by using robotic surface and orbiting systems. The Artemis missions will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.
