China3D printingNet, January 26, a group of undergraduate students from ten universities and colleges in the United States-all members of NASA’s Artemis Generation-designed 3D printable, reusable launch and landing pads for future lunar missions.
This concept is called “Lunar Down Relief Device” (Lunar PAD), and its design goal is to use lunar remodeling materials found directly on the surface of the moon.3D printing. It focuses on solving the unresolved problems encountered when starting and landing burns. In this case, the force from the engine exhaust may cause the scattered lunar dust to rise and agitate. Its novel mandala-like internal geometric structure can lead lunar dust to the outside in the form of laminar flow, thereby reducing the intensity of the originally very turbulent sandstorm caused by the lunar landing.
The student team even published a research paper on its conceptual landing platform at the 2021 Science and Technology Forum of the American Academy of Aeronautics and Astronautics earlier this month. John Dankanich, chief technician of NASA’s Marshall Space Flight Center, said: “When you browse this publication, the diversity of students and schools is very unique. Working with various teams to develop solutions for NASA Innovative solutions to technological gaps have obvious advantages.”

The design was originally proposed in the NASA proposal writing and evaluation experience in a 12-week training course organized by Dankanich in 2019. This idea was called DUST DEVILS at the time, and its top ranking was funded and supported by a team of subject matter experts within NASA. Then, in June 2020, the research team introduced the final design to Marshall’s experts, and the experts received the funds needed to print and test prototypes on Earth.
Dankanich added: “The proposal solves the technical difficulties because the project can achieve the safe and reusable landing platform required for sustainable lunar exploration. The team worked for hundreds of hours and hired NASA subject matter experts from the concept Developed to the preliminary design. Then, in just a few months, they turned this design and large-scale design into reality.”
The cushion itself consists of two separate layers-the roof where the rocket is located and the internal space, which is filled with channels for redirecting exhaust gas. The roof has slits so that the exhaust can be dispersed throughout the internal passages, and then drawn from the exhaust holes from the vents around the edge of the launch plate. The weight of the rocket is supported by the central cone and divider.
The students built a prototype of an electronic scale in Camp Swift. Filmed via ICON.

To test the feasibility of the design, the students and Marshall’s experts printed a small-scale prototype at Camp Swift, Texas, last year.They used concrete developed by ICON construction company3D printingMachine and special cement-based materials for the project.
Mike Fiske, a space manufacturing engineer in the Jacobs Engineering Group of Marshall Space Technology Development Division, added: “Last year it was a pleasure to work with these students and help advance the latest technological mats in planetary launch and landing.”
Fiske and the students plan to return to Camp Swift in late February to test the prototype pad through real rocket thermal tests and material sample evaluations under high temperature and pressure. In the printing process, the instruments needed to measure parameters such as temperature, strain and exhaust flow are integrated into the backing plate.
In addition to the landing zone, NASA has been working on the idea of space manufacturing for many years.The space agency initially selected the engineering company COSM Advanced Manufacturing Systems to develop an automated electron beam in 20173D printingmachine.The company recently announced that it has begun the final development and construction of DED-based metals3D printingmachine. Meet NASA’s needs for space component maintenance.
Elsewhere, scientists at the Technical University of Braunschweig and the Hannover Laser Center recently performed the first in zero gravity3D printingMoon heavy stone. As part of the “MOONRISE” project, the team installed a custom laser on its “MIRA3D” lunar rover and melted moon dust into a spherical shape, paving the way for a flight-ready model that could enable future aerospace The member creates a long-term structure of the moon on it.
