**Title: The Future of Lunar Landings: Exploring the Impact of Rocket Exhaust on the Moon’s Surface**
**Introduction**
NASA’s Artemis campaign aims to send astronauts to the Moon and pave the way for crewed missions to Mars. To achieve this goal, the agency has partnered with SpaceX and Blue Origin to develop human landing systems for safe transportation between the Moon’s surface and space. However, the engines of these landers can potentially create craters, instability, and send regolith particles flying when they ignite or land. To better understand this phenomenon, NASA’s engineers and scientists at the Marshall Space Flight Center in Huntsville, Alabama, have recently conducted a series of test fires using a 3D-printed hybrid rocket motor. This article explores the key findings and implications of these tests and predicts potential future trends for lunar landings.
**Understanding the Effects of Rocket Exhaust on the Moon’s Surface**
The Moon’s surface, known as regolith, has been shaped over billions of years by asteroid and micrometeoroid impacts. It consists of fragments ranging from boulders to powdered particles. The composition of regolith varies across different locations on the Moon, with some areas having denser regolith capable of supporting structures like landers more effectively.
The goal of the recent test fires at NASA’s Marshall Space Flight Center was to study the interaction between the exhaust from commercial human landing systems and the Moon’s regolith. A 14-inch hybrid rocket motor, developed at Utah State University, was used to generate a powerful stream of exhaust by igniting both solid fuel and gaseous oxygen. By firing the motor into a simulated lunar regolith field in a vacuum chamber, NASA aimed to obtain data that could be scaled up to understand the physics of rocket-surface interaction during actual landings.
**Implications for the Artemis Mission and Future Missions**
The findings from the test fires will play a crucial role in ensuring the safety of astronauts during lunar landings as part of the Artemis mission. By studying the size and shape of the craters created by the rocket exhaust and measuring the speed and direction of regolith particles when they come in contact with the exhaust, NASA can refine its data models and improve the landing process. This knowledge will be particularly crucial as the Artemis landers are larger and more powerful than their Apollo predecessors.
The testing will continue at NASA’s Langley Research Center in Virginia, where the hybrid motor will be fired into simulated lunar regolith. This phase will closely simulate real rocket engine conditions and help researchers gather more accurate data. By characterizing the effects of rocket engines on the lunar surface through ground testing in a large vacuum chamber, NASA aims to reduce risks to the crew, lander, payloads, and other surface assets.
**Future Trends and Predictions**
As NASA continues to gather data and refine its understanding of rocket-surface interaction on the Moon, several future trends and predictions can be made:
1. **Improved Landing Techniques**: The knowledge gained from these tests will inform future landing techniques, enabling precise and controlled descent onto the lunar surface. This will reduce the potential for damage to the surface and enhance safety for astronauts.
2. **Advancements in Material Design**: The data collected during these tests will inform the design and development of materials that can better withstand the impact of rocket exhaust on the Moon’s surface. This could involve the use of innovative coatings or reinforced structures to minimize disruption.
3. **Space Tourism and Lunar Mining**: With the successful development of human landing systems and a better understanding of the effects of rocket exhaust, commercial entities could potentially be allowed to participate in lunar missions. This could pave the way for space tourism and lunar mining operations, opening up new frontiers for exploration and resource utilization.
4. **Preparation for Mars Missions**: As NASA’s Artemis mission lays the groundwork for crewed missions to Mars, the knowledge gained from studying rocket-surface interaction on the Moon will be invaluable. Analogous tests and simulations can be conducted to understand similar phenomena on the Martian surface, ensuring safer landings and better mission outcomes.
**Conclusion**
NASA’s recent test fires of a 3D-printed hybrid rocket motor mark an important step toward understanding the impact of rocket exhaust on the Moon’s surface. By studying the interaction between the landers’ engines and the regolith, NASA can make advancements in landing techniques, material design, and mission preparations for both the Artemis campaign and future Mars missions. The data gathered from these tests will contribute to safer lunar landings and pave the way for commercial involvement in space exploration. As we expand our knowledge of rocket-surface interaction, the possibilities for scientific discovery, economic benefits, and human exploration in the depths of space continue to grow.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Astronauts returning to the Moon as part of NASA’s Artemis campaign will face harsh conditions that require testing and development of next-generation spacesuits. To support this effort, NASA’s Jet Propulsion Laboratory (JPL) in Southern California has built a unique chamber called CITADEL (Cryogenic Ice Testing, Acquisition Development, and Excavation Laboratory). Originally designed for testing potential robotic explorers for ocean worlds like Jupiter’s moon Europa, CITADEL is now being used to evaluate spacesuit gloves and boots in extreme cold.
The glove testing campaign in CITADEL, conducted by the NASA Engineering and Safety Center, took place from October 2023 to March 2024, while the boot testing, led by the Extravehicular Activity and Human Surface Mobility Program at NASA’s Johnson Space Center, was conducted from October 2024 to January 2025. The next step is to adapt CITADEL for testing spacesuit elbow joints and incorporate abrasion testing and lunar regolith simulant for the first time.
The Moon’s South Pole, where the Artemis III mission will take place, is known for its extreme conditions, with temperatures as low as minus 414 degrees Fahrenheit (minus 248 degrees Celsius). The CITADEL chamber approximates these temperatures, making it a valuable tool for testing the limits of spacesuit gloves and boots.
One of the goals of the CITADEL experiments is to identify vulnerabilities in existing spacesuits and develop standardized and repeatable test methods for the next-generation lunar suit being built by Axiom Space, the Axiom Extravehicular Mobility Unit (xEMU). By using CITADEL and modern manikin technology, NASA can test design iterations faster and at a lower cost than traditional human-in-the-loop testing, while still ensuring spacesuit safety.
With the data collected from CITADEL testing, NASA can quantify the capability gap of the current hardware and provide feedback to the Artemis suit vendor. The testing also helps NASA assess future hardware designs and mitigate risks to astronauts on future Moon missions.
The CITADEL chamber, which utilizes compressed helium, is equipped with load locks for quick adjustments during testing, cryocoolers to chill the chamber, and aluminum blocks to simulate tools and the lunar surface. It also features a robotic arm and multiple cameras for recording operations.
The article emphasizes the importance of testing spacesuit gloves and boots, as they make prolonged contact with cold surfaces and tools. Understanding the risks and capabilities of the current hardware is crucial for ensuring the safety of astronauts on future Moon missions.
In conclusion, the use of the CITADEL chamber at NASA’s JPL for testing spacesuit gloves and boots in extreme cold conditions is a significant step towards developing next-generation spacesuits suitable for the harsh environments of the Moon’s South Pole. The data collected from these tests will inform the design and development of the Axiom Extravehicular Mobility Unit and future spacesuit designs. By utilizing modern manikin technology and advanced testing methods, NASA can accelerate the testing process and reduce costs while still ensuring astronaut safety.
