Europe to Send Drill to the Moon in Search of Water

The Moon has always fascinated humanity, but recent advancements in space exploration have reignited interest in our closest celestial neighbor. With plans to establish permanent lunar bases, the European Space Agency (ESA) is taking a significant step forward by sending a drill and mini laboratory to the Moon in 2027 as part of their Prospect mission. This mission, aimed at finding and analyzing water and other essential resources on the Moon, is crucial for the future of human exploration and long-term habitation on the lunar surface.

Water is the cornerstone of life, and its presence on the Moon was a groundbreaking discovery. In 2009, NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) confirmed the existence of water on the Moon. This discovery was monumental because it suggested that future human explorers could potentially harvest lunar water for drinking, oxygen production, and even rocket fuel.

Lunar water primarily exists in the form of ice, found in the permanently shadowed craters located in the polar regions of the Moon. These areas, where sunlight never reaches, create an environment where water ice can remain stable for billions of years. However, accessing this water is no small feat, as the polar regions are some of the harshest and most challenging environments on the lunar surface.

The Prospect Mission: Europe’s Lunar Ambition

The ESA’s Prospect mission aims to help us better understand resources on the Moon. This mission is set to launch in 2027. It will travel to the Moon with the help of NASA’s Commercial Lunar Payload Services (CLPS) program. The Prospect probe will carry a drill called ProSEED and a small lab known as ProSPA. These tools will work together to explore the water and other materials hidden below the Moon’s surface.

The ProSEED drill is designed to penetrate the lunar regolith—the layer of loose, fragmented material covering the solid bedrock—up to a depth of one meter. At this depth, temperatures can drop to below -100°C, allowing any water present to remain frozen. ProSEED’s mission is to collect samples from this icy layer and transfer them to the ProSPA laboratory for analysis.

ProSEED is not just a drill; it is a sophisticated tool equipped with advanced technology. It carries a multispectral imager and a permittivity sensor, which allow it to analyze the composition of the lunar surface material as it drills. The multispectral imager can detect different types of minerals and volatile substances, while the permittivity sensor measures the electrical properties of the material to further identify its composition.

Once the samples are collected by ProSEED, they are transferred to the ProSPA laboratory for detailed analysis. ProSPA is a compact, high-tech laboratory designed to analyze the nature and concentration of volatiles within the lunar samples. It contains multiple ovens arranged in a carousel-like structure, where samples are sealed and heated to release trapped gases.

As the samples are heated, ProSPA will measure the gases released to determine the composition of the volatiles present. This process is crucial for understanding the potential for extracting water and other valuable resources from the Moon. Additionally, ProSPA will test various methods for extracting these volatiles, paving the way for future missions to utilize lunar resources effectively.

Simply knowing that water exists on the Moon is not enough. For future missions and the establishment of lunar bases, it is imperative to understand the quantity, distribution, and accessibility of this water. If lunar water is relatively easy to access, it could be far more economical to extract it on-site rather than transporting it from Earth.

Water on the Moon could be used in several ways. First and foremost, it can be purified and used as drinking water for astronauts. Water can also be split into hydrogen and oxygen through electrolysis. The oxygen can be used for breathable air, and the hydrogen can be combined with oxygen to create rocket fuel. This capability would be a game-changer for deep space exploration, as it would reduce the need to carry large quantities of fuel from Earth.

Before any space mission, rigorous testing is essential. The ProSEED drill and ProSPA laboratory have undergone extensive trials in environments that simulate the conditions on the lunar surface. These tests have taken place in facilities that replicate the low temperatures and pressures of the Moon, ensuring that the equipment can withstand the harsh conditions it will encounter.

ProSEED has proven its capability to drill into hard, frozen material and successfully extract samples. These tests are crucial for the success of the mission, as they demonstrate that the equipment can perform as expected in the challenging lunar environment.

The success of the Prospect mission will impact the future of space exploration in many ways. This mission will provide important information about water on the Moon, such as where it is and how easy it is to access. Additionally, it will help plan future missions that want to create a lasting human settlement on the Moon.

Support for Lunar Habitats	Water for sustaining human life and agricultural purposes

The main goal of missions like Prospect is to help humans live on the Moon permanently. To build bases on the Moon, we need resources that can last a long time. Water is one of the most important resources. If we can collect water from the Moon, we can use it to support human life. We can also turn it into oxygen for living spaces and fuel for future space missions.

The Prospect mission is one of many steps toward achieving this goal. Space agencies from different countries are working together and coming up with new ideas. Because of this teamwork, the dream of humans living permanently on the Moon is becoming more possible. The information and experience we get from the Prospect mission will be very useful for future missions. It will help us design places to live on the Moon and create the technology we need to survive there.

By Jonathan Bala August 22, 2024

Axiom Space and Nokia: Partnering for Cutting-Edge Wireless Spacesuit Technology

Axiom Space and Nokia are developing a 4G/LTE communication system for Artemis spacesuits.
The LSCS technology will offer high-speed communication for astronauts on the lunar surface.
The system will enhance scientific operations by enabling real-time data transmission and high-definition video streaming.
The technology provides redundancy for existing communication links, offering increased safety and reliability.
The LSCS system will be tested on the moon during a robotic mission scheduled for late 2024.
The partnership is part of a larger effort to develop a sustainable lunar infrastructure for future missions.

A New Era in Lunar Communication: Axiom Space and Nokia’s Groundbreaking Partnership

The race to establish a sustainable human presence on the moon has led to some of the most innovative partnerships in space exploration history. Among these, the collaboration between Axiom Space and Nokia stands out as a significant leap forward. Announced on August 21, 2024, this partnership aims to integrate cutting-edge 4G/LTE wireless communication technologies into the spacesuits that Axiom Space is developing for NASA’s Artemis program.

At the heart of the Axiom-Nokia collaboration is the Lunar Surface Communications System (LSCS), a sophisticated communication network designed to support the Artemis spacesuits. The LSCS system will consist of two main components:

Network in a Box: This includes a base station, antennas, and other supporting systems installed on the Human Landing Services lander.
User Module: Integrated within Axiom’s spacesuits, this module will enable astronauts to connect to the LSCS seamlessly.

The system aims to provide redundancy for existing communication channels, such as UHF and Wi-Fi, while significantly increasing bandwidth. This enhancement allows for high-definition video streaming, real-time data transmission, and improved communication between astronauts and mission control.

The Artemis program, a critical part of NASA’s long-term lunar exploration goals, seeks to return humans to the moon by 2026. Axiom Space’s involvement in developing the next-generation extravehicular activity (EVA) suits is crucial to this mission. The addition of Nokia’s 4G/LTE technology will elevate the capabilities of these suits, allowing astronauts to perform more complex tasks with higher efficiency.

Russell Ralston, Axiom Space’s executive vice president of extravehicular activity, highlighted the importance of this technology in a recent interview. “From a suit perspective, we like this because it will give us a lot more capability and it gives us a little bit more redundancy in the communications,” he said. The LSCS technology offers a unique blend of reliability and versatility, providing astronauts with multiple communication options based on mission requirements.

One of the most significant benefits of the LSCS technology is its potential to revolutionize scientific operations on the lunar surface. The system enables scientists and geologists supporting the mission from Earth to gain a clearer, real-time understanding of the crew’s observations. By streaming high-definition video directly from the suit’s cameras, mission control and research teams can collaborate more effectively, making informed decisions with minimal delay.

“From a scientific perspective, what it means is all of the scientists and geologists supporting the NASA mission in real-time will have much better insight into what the crew is seeing,” Ralston explained. “People will connect with the mission a lot more closely when they can see it in such rich detail.”

Axiom Space and Nokia Partnering for Cutting-Edge Wireless Spacesuit Technology

Before being incorporated into Axiom’s spacesuits, Nokia’s LSCS system will undergo rigorous testing during the IM-2 mission, the second robotic lunar lander mission by Intuitive Machines. This mission, scheduled for late 2024, will test the system’s ability to provide communication between the lander, a rover, and a “hopper” developed by Intuitive Machines. While the success of this mission is not a must for using LSCS on Axiom’s suits, it provides valuable insights for future Artemis missions.

Thierry Klein, president of Bell Labs Solutions Research at Nokia, noted that the technology could be adapted for future missions involving a lunar rover. Nokia is also exploring how this technology could be utilized in a commercial lunar economy over the next 10 to 15 years through its participation in DARPA’s LunA-10 study.

NASA’s commitment to developing advanced spacesuit technology is reflected in its recent $57.5 million task order to Axiom Space, part of the larger Exploration Extravehicular Activity Services (xEVAS) contract. This task order funds the integration of the LSCS technology into the Artemis suits, marking a significant milestone in the development process.

Axiom Space is now entering the critical design review (CDR) phase of suit development, a period that will continue into early 2025. “We’re approaching that point in time where the design is really solidifying,” Ralston said. He emphasized the importance of having Nokia’s technology incorporated before the CDR phase is completed, ensuring that the final design fully integrates the LSCS capabilities.

Table 1: Key Milestones in the Axiom-Nokia Partnership

Milestone	Date	Description
Partnership Announcement	August 21, 2024	Axiom Space and Nokia announce collaboration to develop LSCS for Artemis spacesuits.
IM-2 Robotic Mission	Late 2024	Nokia tests LSCS technology on the moon during Intuitive Machines’ IM-2 mission.

Artemis 3 Mission	No earlier than 2026	First use of Axiom’s LSCS-equipped spacesuits on a crewed lunar mission.

The LSCS technology is designed to be user-friendly, with seamless integration into the spacesuits. Astronauts can choose between different communication options based on their mission needs, whether it be UHF, Wi-Fi, or 4G/LTE. This flexibility allows for tailored communication strategies that can adapt to the unique challenges of each lunar mission.

Moreover, the LSCS system is built to operate efficiently at distances of up to two kilometers from the lander, meeting NASA’s requirements for the Artemis 3 mission. However, Nokia’s testing has shown that the system can potentially exceed this range in certain configurations, opening the door for even more ambitious lunar exploration activities in the future.

The collaboration between Axiom Space and Nokia is not just about enhancing communication for lunar missions; it’s part of a broader vision to establish a sustainable lunar economy. Nokia’s participation in DARPA’s LunA-10 study reflects this ambition. The study explores how communication networks like LSCS could support commercial activities on the moon, from mining operations to lunar tourism.

As the technology matures, it could become a critical infrastructure component for a thriving lunar economy, enabling everything from autonomous robotic operations to real-time video feeds for remote lunar workers.

The integration of Nokia’s LSCS into Axiom’s spacesuits represents a new standard in spacesuit technology. By combining cutting-edge wireless communication with robust, adaptable suit design, Axiom Space is setting the stage for a new era of lunar exploration.

The modularity of the LSCS allows for future upgrades and modifications, ensuring that the suits remain relevant as NASA and its partners push the boundaries of human exploration. This adaptability is crucial as NASA plans more complex missions, including establishing a permanent lunar base and eventually sending humans to Mars.

NASA’s Lunar Orbiter Discovers Hidden Tunnels Beneath the Moon’s Surface

The presence of conduits below the lunar surface has been theorized and extensively debated for at least 50 years. The analysis of NASA Lunar Reconnaissance Orbiter (LRO) radar data reveals what lies below the Mare Tranquillitatis. A team of international scientists, led by the University of Trento, Italy, has published a research study making a milestone discovery about the Moon. For the first time, scientists have demonstrated the existence of a tunnel in the lunar subsurface, which appears to be an empty lava tube. The research study was published on July 15, 2024, in the journal Nature Astronomy and is the result of an international collaboration.

Evidence of Lunar Caves

“These caves have been theorized for over 50 years, but it is the first time ever that we have demonstrated their existence,” explains Lorenzo Bruzzone, professor at the University of Trento. How was this demonstration achieved? Bruzzone explains: “In 2010, as part of the ongoing LRO NASA mission, the Miniature Radio-Frequency (Mini-RF) instrument acquired data that included a pit in Mare Tranquilitatis. Years later, we have reanalyzed these data with complex signal processing techniques we have recently developed and discovered radar reflections from the area of the pit that are best explained by an underground cave conduit. This discovery provides the first direct evidence of an accessible lava tube under the surface of the Moon.”

Techniques and Technology in Lunar Research

“Thanks to the analysis of the data we were able to create a model of a portion of the conduit,” continues Leonardo Carrer, a researcher at the University of Trento. “The most likely explanation for our observations is an empty lava tube.” The Mini-RF principal investigator, Wes Patterson, from the Johns Hopkins Applied Physics Laboratory adds, “This research demonstrates both how radar data of the Moon can be used in novel ways to address fundamental questions for science and exploration and how crucial it is to continue collecting remotely sensed data of the Moon. This includes the current LRO mission and, hopefully, future orbiter missions.”

Implications for Lunar Exploration

The study, partially funded by the Italian Space Agency, also involved researchers from the University of Padua and La Venta Geographic Explorations APS, who contributed to the geological analyses and the modeling of the identified conduit. The study has scientific importance and implications for the development of missions to the Moon, where the environment is hostile to human life. Surface temperatures on the illuminated side of the Moon can reach 127°C (261°F), while temperatures on the unilluminated side can drop to -173°C (-279°F). Cosmic and solar radiation can be as much as 150 times more powerful on the lunar surface than we experience on Earth, and there is a constant threat of meteorite impact. These conditions drive a need to find safe sites for the construction of infrastructure that can support sustained exploration. Caves such as this one offer a solution to that problem.

The Significance of the Discovery

This discovery is a significant milestone in lunar exploration. The existence of these lava tubes provides potential safe havens for future lunar bases, offering protection from the harsh surface conditions. The temperature extremes and high radiation levels on the lunar surface make it challenging for sustained human presence. However, the stable environment within these lava tubes could mitigate these challenges, providing a controlled setting for habitation and other activities.

Future Prospects and Missions

The confirmation of lunar lava tubes opens new avenues for future missions. These tunnels could be explored further to understand their extent, structure, and potential for use. Future lunar missions could focus on detailed mapping and exploration of these tunnels, assessing their suitability for various purposes, including habitats, research stations, and storage facilities.

The Role of Technology in the Discovery

The discovery was made possible through the use of advanced radar technology and signal processing techniques. The Mini-RF instrument on the LRO played a crucial role in this discovery. The data collected by the Mini-RF were reanalyzed using newly developed signal processing techniques, which allowed the team to detect the radar reflections indicative of an underground cave conduit. This technological advancement highlights the importance of continued innovation and development in space exploration tools and methods.

International Collaboration in Lunar Research

The research study is a testament to the power of international collaboration. Scientists from various institutions and countries worked together to achieve this milestone discovery. The collaboration between the University of Trento, the University of Padua, La Venta Geographic Explorations APS, and the Johns Hopkins Applied Physics Laboratory demonstrates the global nature of space exploration and the collective effort required to make significant advancements.

The Geological Perspective

From a geological perspective, the discovery of lunar lava tubes offers insights into the Moon’s volcanic history. These tubes are formed by flowing lava that cools and solidifies on the surface while the molten lava continues to flow beneath, eventually leaving behind an empty tube. Understanding these structures can provide valuable information about the Moon’s volcanic activity and its geological evolution.

Practical Applications of Lunar Lava Tubes

The practical applications of lunar lava tubes extend beyond habitation. These tunnels could serve as natural shelters for scientific instruments, protecting them from the extreme temperatures and radiation on the lunar surface. They could also be used for storing supplies and equipment, ensuring their longevity and functionality. Moreover, these tunnels could play a role in future resource extraction activities, providing access to lunar materials with minimal exposure to the harsh surface conditions.

Quotes from the Research Team

Lorenzo Bruzzone, professor at the University of Trento, emphasized the significance of the discovery: “These caves have been theorized for over 50 years, but it is the first time ever that we have demonstrated their existence.” Wes Patterson, from the Johns Hopkins Applied Physics Laboratory, highlighted the importance of continued data collection: “This research demonstrates both how radar data of the Moon can be used in novel ways to address fundamental questions for science and exploration and how crucial it is to continue collecting remotely sensed data of the Moon.”

Conclusion

The discovery of hidden tunnels beneath the Moon’s surface is a groundbreaking achievement in lunar exploration. The confirmation of lunar lava tubes provides new opportunities for future missions and the potential for safe, sustainable habitation on the Moon. This discovery underscores the importance of international collaboration, technological innovation, and continued exploration to unlock the mysteries of our celestial neighbor.

Artemis Program: Why a Moon Base Will Need a Transport System

By Jonathan Bala July 9, 2024

Artemis Program: Why a Moon Base Will Need a Transport System

Key Takeaway

The Artemis Program aims to establish a permanent human presence on the Moon, necessitating advanced transport systems to move astronauts and cargo efficiently. Addressing logistical, scientific, and technical requirements, these transport systems will play a crucial role in ensuring the success of lunar missions and the sustainability of human activities on the Moon.

Summary

NASA’s Artemis Program will return astronauts to the Moon for the first time since 1972.
The program aims to establish a permanent human presence on the Moon.
Transport systems are essential for moving astronauts and cargo on the lunar surface.
The 2024 Moon to Mars Architecture white paper highlights the need for lunar mobility systems.
NASA’s objectives include the delivery of crews, supplies, experiments, and habitats.
The Lunar Terrain Vehicle (LTV) and Pressurized Rover (PR) are part of the Artemis Base Camp.
The Artemis Program is divided into three segments: Human Lunar Return (HLR), Foundational Exploration (FE), and Sustained Lunar Evolution (SLR).
The program’s initial missions will require enhanced transport capabilities for crew and cargo.
The lunar surface presents unique challenges, including regolith, lighting conditions, and terrain.
Autonomous and teleoperated systems will be vital for mobility on the Moon.
Energy and environmental considerations are crucial for the design of lunar transport systems.
Future mobility systems will need to be interoperable and capable of autonomous operation.
NASA will address these requirements in the 2024 Architecture Concept Review (2024 ACR).

Artemis Program: Why a Moon Base Will Need a Transport System

NASA’s Artemis Program will send astronauts back to the Moon. The last visit was Apollo 17 in 1972. The next mission is planned for September 2026. NASA will then build the systems needed for yearly trips to the Moon. This will lead to humans living there permanently. There will be a big need for cargo delivery systems. These systems must help with the needs of the crews. They must support their exploration with the right logistical, scientific, and technical support.

We need transportation systems not just for delivering crews and cargo. They must also handle logistical needs and help exploration efforts. These needs were described in a 2024 Moon to Mars Architecture white paper. The paper is titled “Lunar Mobility Drivers and Needs.”

It follows another paper called “Lunar Surface Cargo.” This new white paper talks about the need for lunar infrastructure. Such infrastructure will help move astronauts and payloads from landing sites to important locations. As usual, they found a big gap between what we can currently do and what we expect to need.

The authors again stress the need for mobility systems. These systems should align with NASA’s goals. These goals are outlined in the Moon to Mars Architecture Definition Document (ADD). The authors say recent studies show something important. We need transport systems on the lunar surface. These systems should move cargo from delivery points to usage points. This cargo can include crew supplies, scientific demonstrations, and large infrastructure that needs precise moving.

In short, in addition to landers capable of delivering crews, supplies, experiments, and habitats, NASA’s Moon to Mars program also requires vehicles and support networks that can deliver them from point A to point B. As they state, the currently defined mobility elements are either primarily for crew use or are limited in mobility. This includes elements like the Lunar Terrain Vehicle (LTV) and the Pressurized Rover (PR) – which are elements of the Artemis Base Camp – and robotic missions contracted through the Commercial Lunar Payload Services (CLPS) program.

In addition, the needs and challenges that will emerge as the Artemis Program unfolds are broken down into three segments: Human Lunar Return (HLR), Foundational Exploration (FE), and Sustained Lunar Evolution (SLR). The HLR segment includes the Artemis III mission, currently scheduled for September 2026, where a crew of two will land on the lunar surface using a Starship HLS. The FE segment will coincide with Artemis IV and Artemis V (2028 and 2030), where crew sizes will expand from two to four, and the necessary infrastructure will expand.

After that, during the SLR segment, NASA plans to mount a mission a year and establish a permanent lunar habitat. Throughout this period, the demands for payloads and transportation systems will exceed current capabilities, limited to 15,000 kg (33,070 lbs) of cargo. Similar to what NASA related in their Lunar Surface Cargo whitepaper, accomplishing key mission objectives will require cargo of sizes and masses beyond these capabilities, creating the need for additional solutions.

Mobility demand forecast shows how much transportation will be needed in the future. LTV stands for Lunar Terrain Vehicle. LRV stands for Lunar Roving Vehicle. These are types of transport vehicles used on the moon. NASA compared how well LTV and LRV could meet the future transportation needs.

Isolation and Movement

As the authors state, a major issue on the lunar surface affecting mobility is the need for separation between landing sites and points of use. This separation is motivated by several factors, including science objectives, lighting conditions, and safety considerations. In short, crew vehicles, habitats, and key infrastructure will be positioned at a distance from landing sites so as not to be affected by darkness caused by the landers’ shadow, contamination by the landers, and regolith or blast ejecta created by engine plumes. Based on the level of concern, separation distances are broken down into three tiers:

Separation from lander shadowing: tens of meters (tens of yards)
Lander blast ejecta constraints: due either to separation between the lander and existing infrastructure or lander ascent (>1,000 m; ~1090 yards)
Support for aggregation of elements in ideal habitation zones from available regional landing areas: up to 5,000 m (~5470 yards)

NASA’s Moon to Mars mission architecture emphasizes the need for In-Situ Resource Utilization (ISRU), such as water ice, regolith, and minerals. NASA also recognizes the need to select habitation and hibernation sites that minimize the exposure to darkness from shadows caused by the local topography and the inclination of the Sun during lunar nights (which last two weeks at a time). This is easiest at higher elevations and on top of crater ridges. This necessitates two things:

Exploration, habitation, and power sites will need to be located far from landing and ISRU sites.
Traverses from landing to habitation zones could encounter slopes of up to 20 degrees.

As the authors state, these overlapping challenges can be met by ensuring systems are in place so mission elements can move away from landers once they are deployed on the surface:

“This could be done using independent or integrated mobility systems. The frequency of traverses between downslope and upslope locations would be driven by the cadence with which landers deliver cargo to the lunar surface and the mass that a given mobility system can carry on each traversal. Integrated architecture operations will necessitate non-trivial relocation and aggregation ranges for cargo and assets.”

Transportation Abilities

During the FE segment of the Artemis Program, NASA plans to expand surface crews from two to four, which will need to operate on the surface for about 30 days. This will require a wide range of mobility needs that can accommodate payloads of varying size and mass and over a range of distances. These include:

Smaller technology demonstrations: 500 to 2000 kg (~1100 to 4410 lbs)
Logistic Elements per crewed surface mission: 2,000 to 6,000 kg (~4410 to 13,230 lbs)
Habitation Systems: 12,000 to 15,000 kg (~26455 to 33,070 lbs)

The authors acknowledge that current mobility elements could provide some cargo relocation capabilities – the LTV, for example, can accommodate 800 kg (~1764 lbs) of cargo when uncrewed. However, according to the NASA team’s analysis, the mobility capacity falls short of demand by 1,000 to 15,000 kg (2,200 to 33,070 lbs) per asset for ranges of 50 to 5,000 m (~55 to 5470 yards). Moreover, the “frequency of relocation needs” (i.e., how often payloads need to be moved) will vary considerably, ranging from single operations for large elements to multiple trips a year for containers and smaller cargo.

Environments

The authors also address how lunar conditions are important when developing mobility systems. One of the greatest hazards on the Moon is regolith (aka. “moondust”), the fine silicate powder that covers much of the surface and sticks to everything it comes into contact with. There are lighting conditions where parts of the South Pole region will be shadowed due to the inclination of the Sun and permanently shadowed regions (PSRs) that experience perpetual darkness. Last is the matter of the terrain, which can be rocky or covered by 1 to 10 m (3.3 to 33 ft) of regolith and where slopes of more than 10 degrees are common.

This combination of factors, they argue, “creates a significant technological gap between existing systems and mobility demands for future exploration.” For starters, energy systems must provide enough power so vehicles can maintain sufficient speeds and carrying capacity and can operate during lunar nights. The authors also recommend conducting more studies on regolith mitigation strategies to prevent wear and tear and the effects regolith could have on electro-mechanical systems. They also stress the need for sufficient autonomy and/or teleoperation, allowing greater flexibility and range.

These autonomous systems must contend with the challenging lunar terrain, map the local topography, recognize obstacles and unpassable regions, and identify optimal pathways to reach their destinations. As the authors note, these systems could offer increased flexibility for mission planning and increase the speed of mobile assets, especially in areas where the terrain interferes with communications and makes remote operations impossible.

Energy and Environmental Demands

The white paper also addresses energy and environmental considerations. As noted already, lunar nights are two weeks long, which poses significant challenges for exploration and habitation. Currently, NASA’s Moon to Mars architecture does not specify how the base camps will be powered, though solar power is considered a safe bet. However, the team notes that generating sufficient power to accommodate lunar operations will require solar power systems with “surface mobility capabilities.”

They also note that lunar mobility systems will need to operate for 12 hours a day for up to 30 days and that proposed systems will need to deliver sufficient power to operate for six to twelve months. The thermal environments are also a serious consideration, with average daytime temperatures reaching 120 °C (248 °F) and nighttime temperatures going down to -170 °C (-274 °F). This creates issues for systems that are required to operate day and night.

Conclusion

NASA sees the need for flexible mobility systems. These systems will help astronauts and cargo move across the lunar surface. The systems must meet the needs of the Artemis Program. HLR, FE, and SLR segments define these needs. Current systems handle some mobility needs, but there is a gap. Future missions will need more advanced capabilities. The 2024 Architecture Concept Review (2024 ACR) will focus on these needs.

NASA aims to develop new mobile assets. These assets must work together smoothly and operate on their own without constant human control. The Artemis Program will rely on these assets for its first lunar missions in 2026. This includes delivering infrastructure and crew missions in the late 2020s. By the 2030s, NASA wants to have a lasting presence on the Moon. Closing these technology gaps will help astronauts explore and do science on the Moon.
