NASA’s Innovative Imagery of Lunar Lander Plumes: A Leap Toward Future Moon Missions
A groundbreaking development has taken place at NASA’s Langley Research Center in Hampton, Virginia. A dedicated team of scientists and engineers has managed to capture unprecedented images of a lunar lander’s engine plumes interacting with the Moon’s surface. This significant achievement marks a crucial advancement in the understanding of lunar landings as part of NASA’s Artemis campaign, which aims to increase exploration missions to the Moon in the coming years.
The remarkable imagery was acquired by the Stereo Cameras for Lunar-Plume Surface Studies (SCALPSS) 1.1 instrument. These images were taken during the descent and successful soft landing of Firefly Aerospace’s Blue Ghost lunar lander. This event took place on March 2 in the Moon’s Mare Crisium region, under NASA’s Commercial Lunar Payload Services (CLPS) initiative, which collaborates with private companies to deliver scientific and technological payloads to the lunar surface.
The video footage, though compressed and of limited resolution, provides an early sequence of the final descent and landing of the Blue Ghost lander. NASA researchers meticulously stitched together these images captured by SCALPSS 1.1’s four short-focal-length cameras, which were taking photos at a rapid pace of eight frames per second. The sequence starts at an approximate altitude of 91 feet (28 meters) above the lunar surface, offering a visual insight into the interaction between the lunar surface and the lander’s control thruster plumes.
As the Blue Ghost descends, the interaction between its thruster plumes and the Moon’s surface becomes increasingly noticeable. This interaction begins at an altitude of about 49 feet (15 meters). The descent kicks up lunar dust, soil, and rocks — collectively known as regolith — creating a dynamic and complex visual spectacle. Upon the lander’s touchdown, the thrusters cease, allowing the dust to settle, revealing the lunar terrain beneath and around the lander.
Rob Maddock, the SCALPSS project manager, expressed his enthusiasm about the data captured. "Although the data is still preliminary, the more than 3000 images we recorded contain the precise information we sought to better understand plume-surface interaction," Maddock stated. "This knowledge will enable us to accurately model the phenomenon based on the engines’ number, size, thrust, and configuration." He emphasized the importance of this data in minimizing risks in designing and operating future lunar landers and surface infrastructure.
The SCALPSS 1.1 technology comprises a total of six cameras, including four short focal length and two long focal length. The long-focal-length cameras were particularly useful, as they began capturing images at higher altitudes before the plume-surface interaction started. This approach provides a more accurate before-and-after comparison of the lunar surface. By employing stereo photogrammetry, a technique that combines overlapping images to create 3D digital elevation maps, the team aims to deliver a comprehensive topographical analysis of the surface.
The SCALPSS instrument continues to function on the Moon. As the lunar day progresses and light and shadows shift, it will capture more details of the surface beneath and around the lander. The team also hopes to document imagery during the transition to lunar night to observe how dust reacts to these environmental changes.
Michelle Munk, the SCALPSS principal investigator, underscored the significance of SCALPSS’s successful operation in advancing our fundamental understanding of landing and operating on the Moon. "This technology is already providing data that could inform future missions," Munk said, highlighting the potential impact of these findings on upcoming lunar expeditions.
The extensive data from the Blue Ghost landing will take several months to fully process. The team plans to release the raw images from SCALPSS 1.1 to the public through NASA’s Planetary Data System within six months. Meanwhile, preparations are underway for the next SCALPSS flight aboard Blue Origin’s Blue Moon lander, set to launch later this year. Before its deployment, the next version of SCALPSS will undergo rigorous thermal vacuum testing at NASA Langley to ensure its readiness for the mission.
The SCALPSS 1.1 project is generously supported by the Space Technology Mission Directorate’s Game Changing Development program. This initiative is a testament to NASA’s commitment to fostering innovation and collaboration in lunar exploration.
NASA’s CLPS initiative is instrumental in advancing lunar exploration by partnering with various American companies. Selected vendors bid on delivering payloads for NASA, encompassing a range of responsibilities from payload integration and operations to launching from Earth and landing on the Moon’s surface. This collaborative approach not only accelerates technological advancement but also paves the way for more frequent and successful lunar missions.
In summary, the SCALPSS project’s achievements represent a significant leap forward in our understanding of lunar landings. By capturing and analyzing the intricate interactions between lunar lander plumes and the Moon’s surface, NASA is equipping future missions with the data necessary to enhance safety and efficiency. As space exploration continues to evolve, endeavors like these underscore the importance of innovation, collaboration, and scientific curiosity in pushing the boundaries of what is possible.
