铀的放射性很难用在建造方面,军事方面却有关键用途;当然除了作为制造材料,铀棒主要用于能量燃料。
Space Engineers is a science-fiction survival and building game. This voxel-based game resembles Minecraft in its basic structure: players must mine resources and fend off enemies to survive in a hostile world but the real fun is building exciting and elaborate structures including space ships and...
Coming back,KREEP, a new rock found, is named before the initials of potassium (K),rare-earthelements, andphosphorous on the moon’s surface. The near side has regions with items like Uranium, Thorium which is rarely present on the other sides of the moon. These will help to know about...
Space Engineers is a sandbox game about engineering, construction, exploration and survival in space and on planets. Players build space ships, space stations, planetary outposts of various sizes and uses (civil and military), pilot ships and travel...
The current campaign is the second deployment of IMPACTS and is scheduled to wrap up at the end of the month. Engineers at our Stennis Space Center conducted the second RS-25 engine hot fire test of 2022 on February 8. Four RS-25s will help power our Space Launch System rocket on futu...
The measured quantity in a GR log is counts of the gamma rays emitted from three naturally occurring radioactive elements: thorium (Th), uranium (U) and potassium (K). When there is sufficient difference of GR responses among formations, GR is primarily used as the stratigraphic measurement ...
Small heatshield specimens have undergone arc jet evaluation using what NASA engineersdescribe as a "room-size blowtorch". The CEVThermal Protection System, Advanced Development Project at Ames is geared tocreate and test the 16.5-foot (5-meter) diameter, Frisbee-shaped heat shieldthat will be at...
NASA and NNSA engineers lower the wall of the vacuum chamber around the Kilowatt Reactor Using Stirling TechnologY (KRUSTY system). The vacuum chamber is later evacuated to simulate the conditions of space when KRUSTY operates. Credit: Los Alamos National Laboratory ...
To design this new giant telescope, engineers will likely draw from two proposed observatory ideas that have already been sketched out in detail. Before completing the decadal survey, four teams of scientists came up with four different proposals for space telescopes, providing a framework for what...
The space environment is regularly used for experiments addressing astrobiology research goals. The specific conditions prevailing in Earth orbit and beyond, notably the radiative environment (photons and energetic particles) and the possibility to conduct long-duration measurements, have been the main moti...
