Problem: how to transport raw materials from whistle-stop asteroid belts in the boondock sectors to the space factories of the UFP? And I'm not talking a freighter or two here. I'm talking about the billions and billions of metric tonnage needed each stardate to feed the Federation's rave...
NASA has an extensive program for studying materials and methods for the shielding of astronauts to reduce the effects of space radiation when on the surfaces of the Moon and Mars, especially in the use of in situ materials native to the... CA Theriot,B Gersey,E Bacon,... 被引量: 4...
Smart materials coating the windows and reflectors prevent fluctuations in solar activity from delivering too much heat. The air inside the cylinder and its metal superstructure provide radiation shielding. The land in most O'Neill cylinders is one-third agricultural (a combination of food vats and...
In order to reduce the overall space craft mass, NASA is looking for the novel, multi-purpose and multi-functional materials that will provide effective shielding of the crew and electronics on board. The Laboratory for Neutronics and Geometry Computation in the School of Nuclear Engineering at ...
The materials discussed include self-healing polymers, fire and thermally resistant materials, materials for thermal management, self-cleaning materials, EMI shielding materials and multifunctional carbon fibre composites. Through this catalogue, we seek to inform and suggest the future direction of ...
The researchers also conducted chemical experiments to ensure the printing materials were compatible with the conductive l ... more NASA CubeSat Finds New Radiation Belts After May 2024 Solar Storm Greenbelt MD (SPX) Feb 12, 2025 The discovery of the new belts, made possible by NASA's Colorado...
Inside the ISS, secondary particles including neutrons are also generated as the primary particles penetrate through the shielding materials of the spacecraft. High energy charged particles, which possess high linear energy transfer (LET) are known to cause more damage in comparison to gamma or X-...
