摘要

The National Aeronautics and Space Admin. (NASA, Washington, D.C.) announced on July 2 that it recently completed a major space technology development milestone by successfully testing a large, pressurized cryogenic propellant tank made of composite materials. The composite tank will hold fuel for the next generation of rockets and spacecraft needed for space exploration. Cryogenic propellants, which are gas-ses chilled to subfreezing temperatures and condensed to form highly combustible liquids, provide the high-energy propulsion solutions critical to future long-term human exploration missions beyond low-Earth orbit. Liquid oxygen and liquid hydrogen have been the traditional cryogenic propellants used to provide the enormous thrust to launch large rockets and Space Shuttles.
