  • s (MEMS), also known as microsystems technology in Europe, or micromachines in Japan, are a class of
  • smaller than the diameter of a human hair
  • However, MEMS parts are not machined. Instead, they are created using micro-fabrication technology similar to batch processing for integrated circuits.

  • Likewise, the types of MEMS devices can vary from relatively simple structures having no moving elements, to extremely complex electromechanical systems with multiple moving elements under the control of integrated microelectronics.
  • including temperature, pressure, inertial forces, chemical species, magnetic fields, radiation, etc.

  • conflict between idea of slavery under the grim oligarchy of the Kremlin
  • The implacable purpose of the slave state to eliminate the challenge of freedom has placed the two great powers at opposite poles. It is this fact which gives the present polarization of power the quality of crisis.
  • marvelous diversity, the deep tolerance, the lawfulness of the free society.

NASA Eyeing Nuclear Fusion Rockets for Future Space Exploration | Advanced Propulsion C... - 0 views

  • Nuclear fusion rockets could slash travel times through deep space dramatically, potentially opening up vast swathes of the solar system to human exploration
  • You could get to Saturn in a couple of months
  • Traditional chemical propulsion systems can get humans to destinations in deep space, but with a lot of travel time. For example, a roundtrip manned mission to the vicinity of Mars, which NASA aims to execute by the mid-2030s, would require about 500 days of spaceflight.

  • So NASA and researchers around the world have been investigating advanced propulsion technologies, including space-bending "warp drives," enormous solar sails and matter-antimatter engines. Nuclear fusion is perhaps the most promising of these possibilities, at least in the relatively near term, proponents say.
  • Fusion rockets would harness the energy released when the nuclei of two or more atoms combine. Our sun and other stars are fusion-powered, converting this energy to light; the same principle also gives hydrogen bombs their immense destructive power.
  • NASA has funded several early-stage fusion ideas recently via a program called NIAC (NASA Institute for Advanced Concepts). One of these groups, led by scientists at the University of Washington, recently calculated that a fusion rocket could make it possible to get astronauts to Mars in as little as 30 days.
