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.

NASA is seeking proposals from U.S. companies about innovative Moon and Mars proximity relay communication and navigation capabilities as the agency aims to use private industry satellite communications services for emerging missions.
On July 7, NASA issued a Request for Proposals, soliciting advanced industry concepts to establish high-bandwidth, high-reliability communications infrastructure between the lunar surface and an Earth-based operations control center, along with concepts that establish a critical communications relay on the Martian surface and transfer data between Mars and the Earth.
“These partnerships foster important advancements in communications and navigation,” said Greg Heckler, deputy program manager for capability development within NASA’s SCaN (Space Communications and Navigation) Program. “It allows our astronauts, our rovers, our spacecraft – all NASA missions – to expand humanity’s exploration of the Moon, Mars, and beyond.”
NASA’s request directly supports the agency’s long-term vision of an interoperable space communication and navigation infrastructure that enables science, exploration, and economic development in space. NASA, as one of many customers, will establish a marketplace that supports cost-effective commercial services involving communication needs on and around the Moon and Mars.
Responses are due by 5 p.m. EDT, Wednesday, Aug. 13.
NASA’s SCaN Program serves as the management office for the agency’s space communications and navigation. More than 100 NASA and non-NASA missions rely on SCaN’s two networks, the Near Space Network and the Deep Space Network, to support astronauts aboard the International Space Station and future Artemis missions, monitor Earth’s weather, support lunar exploration, and uncover the solar system and beyond.

4 Min Read Vision Changes on Space Station

When astronauts began spending six months and more aboard the International Space Station, they started to notice changes in their vision. For example, many found that, as their mission progressed, they needed stronger reading glasses. Researchers studying this phenomenon identified swelling in the optic disc, which is where the optic nerve enters the retina, and flattening of the eye shape. These symptoms became known as Space-Associated Neuro-Ocular Syndrome (SANS).
NASA astronaut Suni Williams wears a cuff on her left leg as she conducts an eye exam for the Thigh Cuff investigation.NASA Microgravity causes a person’s blood and cerebrospinal fluid to shift toward the head and studies have suggested that these fluid shifts may be an underlying cause of SANS. A current investigation, Thigh Cuff, examines whether tight leg cuffs change the way fluid moves around inside the body, especially around the eyes and in the heart and blood vessels. If so, the cuffs could serve as a countermeasure against the problems associated with fluid shifts, including SANS. A simple and easy-to-use tool to counter the headward shift of body fluids could help protect astronauts on future missions to the Moon and Mars. The cuffs also could treat conditions on Earth that cause fluid to build up in the head or upper body, such as long-term bed rest and certain diseases.
Following fluid shifts
NASA astronaut Shane Kimbrough sets up optical coherence tomography hardware.NASA The Fluid Shifts investigation, conducted from 2015 through 2020, was the first to reveal changes in how blood drains from the brain in microgravity. Vision Impairment and Intracranial Pressure (VIIP) began testing the role those fluid shifts and resulting increased brain fluid pressure might play in the development of SANS. This research used a variety of measures including clinical eye exams with and without dilatation, imaging of the retina and associated blood vessels and nerves, noninvasive imaging to measure the thickness of retinal structures, and magnetic resonance imaging of the eye and optic nerve. In addition, approximately 300 astronauts completed questionnaires to document vision changes during their missions.
In one paper published from the research, scientists described how these imaging techniques have improved the understanding of SANS. The authors summarized emerging research on developing a head-mounted virtual reality display that can conduct multimodal, noninvasive assessment to help diagnose SANS.
Other researchers determined that measuring the optic nerve sheath diameter shows promise as a way to identify and quantify eye and vision changes during spaceflight. The paper also makes recommendations for standardizing imaging tools, measurement techniques, and other aspects of study design.
Another paper reported on an individual astronaut who had more severe than usual changes after a six-month spaceflight and certain factors that may have contributed. Researchers also observed improvement in the individual’s symptoms that may have been due to B vitamin supplementation and lower cabin carbon dioxide levels following departure of some crew members. While a single case does not allow researchers to determine cause and effect, the magnitude of the improvements suggest this individual may be more affected by environmental conditions such as carbon dioxide. This may have been the first attempt to mitigate SANS with inflight B vitamin supplementation.
Eyeball tissue stiffness

On Earth, changes in stiffness of the tissue around the eyeball have been associated with aging and conditions such as glaucoma and myopia. Researchers found that long-duration spaceflight affected the mechanical properties of eye tissues, which could contribute to the development of SANS. This finding could improve understanding of eye changes during spaceflight and in aging patients on Earth.
Genetic changes, artificial gravity
The MHU-8 investigation from JAXA (Japan Aerospace Exploration Agency), which examined changes in DNA and gene expression in mice after spaceflight, found changes in the optic nerve and retinal tissue. Researchers also found that artificial gravity may reduce these changes and could serve as a countermeasure on future missions.
These and other studies ultimately could help researchers prevent, diagnose, and treat vision impairment in crew members and people on Earth.

Melissa Harris’ official NASA portrait. NASA/Robert Markowitz With over 25 years of experience in human spaceflight programs, Melissa Harris has contributed to numerous programs and projects during key moments in NASA’s history. As the life cycle lead and Independent Review Team review manager for the Commercial Low Earth Orbit Development Program, she guides the agency through development initiatives leading to a new era of space exploration.
Harris grew up near NASA’s Johnson Space Center in Houston and spent time exploring the center and trying on astronaut helmets. She later earned her bachelor’s degree in legal studies from the University of Houston, master and subject matter expert certifications in configuration management, and ISO 9001 Lead Auditors Certification. When the opportunity arose, she jumped at the chance to join the International Space Station Program.

Image courtesy of Melissa Harris Starting as a board specialist, Harris spent eight years supporting the space station program boards, panels, and flight reviews. Other areas of support included the International Space Station Mission Evaluation Room and the EVA Crew Systems and Robotics Division managing changes for the acquisition and building of mockups in the Neutral Buoyancy Laboratory and Space Vehicle Mockup Facility in Houston. She then took a leap to join the Constellation Program, developing and overseeing program and project office processes and procedures. Harris then transitioned to the Extravehicular Activity (EVA) Project Office where she was a member of the EVA 23 quality audit team tasked with reviewing data to determine the cause of an in-orbit failure. She also contributed to the Orion Program and Artemis campaign. After spending two years at Axiom Space, Harris returned to NASA and joined the commercial low Earth orbit team.
Harris said the biggest lesson she has learned during her career is that “there are always ups and downs and not everything works out, but if you just keep going and at the end of the day see that the hard work and dedication has paid off, it is always the proudest moment.”
Her dedication led to a nomination for the Stellar Award by the Rotary National Award for Space Achievement Foundation.
