Lunar Lava Tube Entrance Mapped by Space Technology

Craters are a familiar sight on the lunar surface and indeed on many of the rocky planets in the Solar System. However, not all circular features on the Moon are craters. Some of these pits are believed to be the collapsed roofs of lava tubes. Researchers have recently mapped one of these tubes using radar reflections, creating the first 3D map of the tube’s entrance. These tubes could be ideal locations for setting up research stations, providing protection from the harsh lunar environment.

What Are Lava Tubes?

Lava tubes have been a subject of debate for the last 50 years. They form due to ancient volcanic activity. When the surface of a lava flow cools and hardens, the molten lava beneath continues to move. Eventually, the molten lava drains away, leaving behind a hollow tunnel. These tunnels can offer a preserved record of the Moon’s geological history.

The Role of NASA’s Lunar Reconnaissance Orbiter (LRO)

NASA’s Lunar Reconnaissance Orbiter (LRO) has been instrumental in the study of lunar lava tubes. Launched in 2009, the LRO’s mission is to gather detailed information about the Moon’s surface and environment. Equipped with scientific instruments, the LRO captures high-resolution imagery, maps temperature variations, measures radiation levels, and identifies water ice deposits.

Breakthrough Discovery by International Team

A team of scientists from around the world, led by the University of Trento in Italy, made a groundbreaking discovery. Published in Nature Astronomy, the team confirmed the existence of a tunnel just beneath the lunar surface. This tunnel is an empty lava tube, a theory that had remained unproven until now.

Key Data from LRO’s Miniature Radio-Frequency Instrument

The discovery was made possible by the LRO’s Miniature Radio-Frequency instrument. In 2010, the instrument surveyed Mare Tranquilitatis, the site of Apollo 11’s historic landing in 1969. The data included information about a nearby pit. Using modern signal processing techniques, researchers reanalyzed the data, revealing previously unidentified radar reflections that suggest an underground cave or tunnel.

This represents an underground tunnel on the surface of the Moon, but it is an accessible tunnel too,” said the research team from the University of Trento.

Importance of Historical Data Analysis

The discovery highlights the significance of analyzing historical data with modern techniques. Decades-old data can reveal new information when reexamined with advanced technology. This finding underscores the need for continued remote sensing and lunar exploration to identify more lava tubes.

Protective Benefits of Lava Tubes

The lunar environment is incredibly harsh. Temperatures can range from 127 degrees Celsius on the illuminated side to -173 degrees Celsius on the night side. Solar radiation on the Moon can be up to 150 times more powerful than on Earth, and there’s no atmosphere to protect against meteorite impacts. Structures built on the lunar surface must withstand these extreme conditions.

However, lava tubes offer natural protection. They can shield against temperature extremes, solar radiation, and meteorite impacts, making them ideal for establishing a lunar presence. Setting up research stations within these tubes could be a safer and more cost-effective solution compared to surface structures.

Future Exploration and Research

The discovery of the lunar lava tube is a significant step forward, but more work is needed. Continued exploration and remote sensing are essential to map additional lava tubes. Identifying these tubes is crucial for planning future lunar missions and establishing a sustainable human presence on the Moon.

Conclusion

The mapping of a lunar lava tube entrance using space technology marks a significant achievement in lunar exploration. Lava tubes, formed by ancient volcanic activity, offer valuable insights into the Moon’s geological history and provide a potential refuge for future lunar explorers. NASA’s Lunar Reconnaissance Orbiter has played a vital role in this discovery, demonstrating the importance of reanalyzing historical data with modern techniques. As we continue to explore the Moon, lava tubes may prove to be key in creating safe and sustainable research stations.

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

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.

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

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.

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:

  1. Exploration, habitation, and power sites will need to be located far from landing and ISRU sites.
  2. 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.
