Two full-scale development model rovers, part of NASA’s Cooperative Autonomous Distributed Robotic Exploration (CADRE) technology demonstration, drive in the Mars Yard at the agency’s Jet Propulsion Laboratory in Southern California in this image from August 2023. The project is designed to show that a group of robotic spacecraft can work together as a team to accomplish tasks and record data autonomously – without explicit commands from mission controllers on Earth.

A series of Mars Yard tests with the development models confirmed CADRE hardware and software can work together to accomplish key goals for the project. The rovers drove together in formation and adjusted their plans as a group when faced with unexpected obstacles.

CADRE is slated to arrive at the Reiner Gamma region of the Moon through NASA’s Commercial Lunar Payload Services (CLPS) initiative. The network of robots will spend the daylight hours of a single lunar day – about 14 Earth days – conducting experiments that will test their capabilities.

      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.

      Precision Combustion
      Precision Combustion, Inc. (PCI) proposes to develop a uniquely compact, lightweight, low-power, and durable Microlith® Thermo-Photo-Catalytic (TPC) Reactor for crewed Mars transit spacecraft O2 supply. As crewed space exploration mission destinations move from low Earth orbit to sustained lunar surface habitation toward Mars exploration, the need becomes more intense to supplant heritage physico-chemical unit operations employed for crewed spacecraft cabin CO2 removal, CO2 reduction, and O2 supply. The primary approach to date has been toward incremental improvement of the heritage, energy intensive process technologies used aboard the International Space Station (ISS), particularly for water electrolysis-based O2 generation. A major breakthrough is necessary to depose these energy intensive process technologies either partly or completely. This is achievable by considering the recent advances in photocatalysis. Applications are emerging for converting CO2 to useful commodity products and generating H2 from atmospheric water vapor. Considering these developments, a low power thermo-photo-catalytic process to replace the heritage high-power water electrolysis process is proposed for application to a Mars transit vehicle life support system (LSS) functional architecture. A key component in realizing this breakthrough is utilizing a catalyst substrate such as Microlith that affords high surface area and promotes mass transport to the catalyst surface. The proposed TPC oxygenator is expected to operate passively to continually renew the O2 content of the cabin atmosphere. The targeted mission for the proposed TPC oxygenator technology deployment is a 2039 Long Stay, Earth-Mars-Earth mission opportunity. This mission as defined by the Moon to Mars (M2M) 2024 review consists of 337.9 days outbound, 348.5 days in Mars vicinity, and 295.8 days return for a total 982.2-day mission. The proposed Microlith oxygenator technology, if successful, is envisioned to replace the OGA technology in the LSS process architecture with significant weight and power savings. In Phase I, we will demonstrate technical feasibility of Microlith TPC for O2 generation, interface requirements, and integration trade space and a clear path towards a prototype demonstration in Phase II will also be described in the final report.

      5 Min Read NASA and Italian Space Agency Test Future Lunar Navigation Technology
      The potentially record-breaking Lunar GNSS Receiver Experiment (LuGRE) payload will be the first known demonstration of GNSS signal reception on and around the lunar surface. Credits: NASA/Dave Ryan As NASA celebrates 55 years since the historic Apollo 11 crewed lunar landing, the agency also is preparing new navigation and positioning technology for the Artemis campaign, the agency’s modern lunar exploration program.
      A technology demonstration helping pave the way for these developments is the Lunar GNSS Receiver Experiment (LuGRE) payload, a joint effort between NASA and the Italian Space Agency to demonstrate the viability of using existing GNSS (Global Navigation Satellite System) signals for positioning, navigation, and timing on the Moon.
      During its voyage on an upcoming delivery to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative, LuGRE would demonstrate acquiring and tracking signals from both the U.S. GPS and European Union Galileo GNSS constellations during transit to the Moon, during lunar orbit, and finally for up to two weeks on the lunar surface itself.
      The Lunar GNSS Receiver Experiment (LuGRE) will investigate whether signals from two Global Navigation Satellite System (GNSS) constellations, the U.S. Global Positioning System (GPS) and European Union’s Galileo, can be tracked at the Moon and used for positioning, navigation, and timing (PNT). The LuGRE payload is one of the first demonstrations of GNSS signal reception and navigation on and around the lunar surface, an important milestone for how lunar missions will access navigation and positioning technology. If successful, LuGRE would demonstrate that spacecraft can use signals from existing GNSS satellites at lunar distances, reducing their reliance on ground-based stations on the Earth for lunar navigation.
      Today, GNSS constellations support essential services like navigation, banking, power grid synchronization, cellular networks, and telecommunications. Near-Earth space missions use these signals in flight to determine critical operational information like location, velocity, and time.
      NASA and the Italian Space Agency want to expand the boundaries of GNSS use cases. In 2019, the Magnetospheric Multiscale (MMS) mission broke the world record for farthest GPS signal acquisition 116,300 miles from the Earth’s surface — nearly half of the 238,900 miles between Earth and the Moon. Now, LuGRE could double that distance.
      “GPS makes our lives safer and more viable here on Earth,” said Kevin Coggins, NASA deputy associate administrator and SCaN (Space Communications and Navigation) Program manager at NASA Headquarters in Washington. “As we seek to extend humanity beyond our home planet, LuGRE should confirm that this extraordinary technology can do the same for us on the Moon.”
      NASA, Firefly, Qascom, and Italian Space Agency team members examine LuGRE hardware in a clean room.Firefly Aerospace Reliable space communication and navigation systems play a vital role in all NASA missions, providing crucial connections from space to Earth for crewed and uncrewed missions alike. Using a blend of government and commercial assets, NASA’s Near Space and Deep Space Networks support science, technology demonstrations, and human spaceflight missions across the solar system.
      “This mission is more than a technological milestone,” said Joel Parker, policy lead for positioning, navigation, and timing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We want to enable more and better missions to the Moon for the benefit of everyone, and we want to do it together with our international partners.”

      The data-gathering LuGRE payload combines NASA-led systems engineering and mission management with receiver software and hardware developed by the Italian Space Agency and their industry partner Qascom — the first Italian-built hardware to operate on the lunar surface.
      Any data LuGRE collects is intended to open the door for use of GNSS to all lunar missions, not just those by NASA or the Italian Space Agency. Approximately six months after LuGRE completes its operations, the agencies will release its mission data to broaden public and commercial access to lunar GNSS research.
      Firefly Aerospace’s Blue Ghost Mission One lander is carrying 10 NASA science and technology instruments to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign.Firefly Aerospace “A project like LuGRE isn’t about NASA alone,” said NASA Goddard navigation and mission design engineer Lauren Konitzer. “It’s something we’re doing for the benefit of humanity. We’re working to prove that lunar GNSS can work, and we’re sharing our discoveries with the world.”
      The LuGRE payload is one of 10 NASA-funded science experiments launching to the lunar surface on this delivery through NASA’s CLPS initiative. Through CLPS, NASA works with American companies to provide delivery and quantity contracts for commercial deliveries to further lunar exploration and the development of a sustainable lunar economy. As of 2024, the agency has 14 private partners on contract for current and future CLPS missions.
      Demonstrations like LuGRE could lay the groundwork for GNSS-based navigation systems on the lunar surface. Bridging these existing systems with emerging lunar-specific navigation solutions has the potential to define how all spacecraft navigate lunar terrain in the Artemis era.

Funding and oversight for the LuGRE payload comes from the agency’s SCaN Program office. It was chosen by NASA as one of 10 funded research and technology demonstrations for delivery to the lunar surface by Firefly Aerospace Inc, a flight under the agency’s CLPS initiative.
